H h
- H, h
- Enthalpy. From the Greek enthalpein, `to heat.' Under conditions
of constant pressure, the enthalpy of reaction (the enthalpy change in a
reaction) is the heat generated. A lot of enthalpies are known by traditional
names like ``heat of reaction'' (which is, in appropriate cases, the almost
redundant-sounding ``heat of combustion'') and ``latent heat'' (``[latent] heat
of fusion,'' ``[latent] heat of vaporization''). I don't know for certain why
it's represented by a symbol aitch; your guess is as good as mine.
Following common practice in thermodynamics, the upper-case letter H
represents the extensive quantity (enthalpy) and the lower-case letter h
is used to represent one or another intensive quantity (a ``specific''
enthalpy: the enthalpy per particle or unit mass, say, in units of calories per
mole or per gram, or whatever else is needed or convenient).
The enthalpy of any homogeneous system of energy E and volume V
at pressure p is given by
E = H + pV .
Enthalpy is a useful quantity to define theoretically, and one that can be
measured rather directly in experiments, for processes that occur in
constant-pressure environments, if and pretty much only if mechanical
work by volume change is the only kind of work performed on or by a system.
In this case, the differential of energy can be written (with T and
S the temperature and entropy) as
dE = TdS - pdV ,
hence
dH = TdS + Vdp .
Note therefore that since volume is positive, increasing pressure under
adiabatic conditions increases enthalpy. The exact differential for enthalpy
yields some obvious identities in the usual way. (In particular, the equality
of the two cross-partials is called a Maxwell relation.)
For systems in which other kinds of work W can be done, it is generally
possible to represent dW by a sum of products of the form FdQ,
where each F is a generalized force and each Q its conjugate (generalized)
coordinate or displacement. (It is true that these may refer at the
microscopic level to mathematical objects that are not ``real-valued'' in the
relevant sense, but thermodynamics is about macroscopic variables, and them's
real, so get a life.) One can thus define a generalized enthalpy by
adding a product FQ for each force. This isn't a very common practice, but the
obvious applications are magnetic and dielectric systems, and elastic systems
under some constant nonisotropic stress.
Chemists now represent energy fairly uniformly by E, but physicists
often use U. That is a helpful hint that you should be watching out for
a different H, the Hamiltonian, described in an
entry close below. If you see it, you are in the realm of statistical
mechanics, which is basically the concrete microscopic foundation of
thermodynamics. Another symbol-table conflict between thermodynamics and
statistical mechanics is at p. This is less of a problem because stat.
mech. p is the length of a vector p, and vectors have a
distinctive font style, but nevertheless it is often convenient to represent
pressure in stat. mech. by a capital P. (Just don't mistake it for the
magnitude of the dielectric polarization vector, okay?) In statistical
mechanics, the thermodynamic quantities one evaluates most directly are free
energies. Moreover, constant-volume calculations are usually more convenient
than constant-pressure. Hence, enthalpy and Hamiltonian symbols don't bump
into each other very much, even though they describe the same physical systems.
- H
- Hamiltonian. The Hamiltonian is a function (in classical physics) or
operator (in quantum physics) that yields the energy (as value of the function
or expectation value of the operator) when evaluated for a physical system in a
particular state. The Hamiltonian is fundamentally the generator of time
translations. In plain language, the Hamiltonian determines how a system
evolves from moment to moment. It all fits together so wonderfully that it's
too beautiful for words, so you have to use mathematics instead.
What, you want to know more?! Look, it's been a long day. Why don't you see

The idea behind the choice is to have words that the listener will be able
to guess at or reconstruct accurately even through noise (or narrow
bandwidth, like a telephone).
You could try just saying ``aitch.'' It's different from the names of
all the other letters.

- H
- Hypothesis. Much of formal statistical inference consists of tests to
determine whether it is plausible that two samples or measurements are drawn
from a common statistical distribution -- that is, that they measure the same
thing. The null hypothesis is this hypothesis of null difference, often
designated as the proposition H0. Occasionally, the null hypothesis
will be more interesting: if one is testing whether the difference between
two samples is accounted for by some known mechanism, source, cause, etc., then
the null hypothesis may be the proposition that the means differ by a given
constant. Alternative hypotheses may be designated H1,
H2, ...

square hectometer.) A hectare is about 2.4711 acres.
The consensus of sources, once corrected for numerical typos, appears to be
that the Aurelian walls of Rome had a length of 18,837 m (or km, if you

- HACCP
- Hazard Analysis and Critical Control Points.
- hacha
- The spelling of two or three words in
Spanish. One word is a
noun meaning axe, and is borrowed from the
French hache with the same meaning,
derived from a Franconian (i.e. Germanic) root that apparently does not
occur independently in English. The diminutive hachette was borrowed in
English (a hatchet is a small axe). [Another Spanish word hacha, if you
want to count it, is the third-person singular, indicative present-tense form
of the verb hachar, `to hew.']
A completely distinct Spanish hacha, now regional and rare, means
`torch.' This word, like the Galician-Portuguese facha or facho,
is thought to be derived from a variant form, probably fascula, of the
Latin facula, `small torch,' diminutive of
fax, `torch.' (It is less probable that the hard cee of facula
would have evolved directly into a ch, though there are other possibilities.)
The idea is that the -sc- in the presumed fascula would have arisen from
confusion of Latin fax with fascis, `bundle,' since torches often
consisted of bundles lit together at one end. (A similar conflation, or simply
combination of meanings, occurs with the English term for a bundle of twigs or
branches normally intended for fuel: faggot.)
That word fascis, in the sense of bundle, has another association with
axes. In ancient Rome, the power of punishment was symbolized by a bunch of
sticks of uniform length, bundled to form a cylinder surrounding an axe, with
part of the blade protruding. Ceremonially, lictors carried these before
superior magistrates as symbols of the magistrates' power. (In this context
the word usually occurred in the plural, which is fasces in the
nominative case.) The symbol was originally used by the Etruscans, and the
Latin Romans kept the symbol after they booted their Etruscan rulers.
The Latin word fascis gave rise to the word fascio (plural
fasci) in Italian, still in the sense of a bundle of rods or sticks.
The fascio was again (but without the axe) adopted as a political symbol
in late-nineteenth-century Italy, on the strength of the metaphorical notion
that though individual sticks are weak, there is strength in unity. From the
symbol, the political groups themselves came to be called fasci.
The term was eventually monopolized by the party created by Benito Mussolini
during and after WWI. For this rightist party,
which drew some authority from the notion that it continued or restored ancient
Roman tradition, the association with the ceremonial Fascis of Rome was also
valued.
I should probably say something about the word axis, since that word was
used by Germany and Italy to describe their political (from 1936) and military
alliance (from 1939 and the start of WWII). The
idea was that the alliance was a metaphorical common pivot or fulcrum, not that
you could connect the two countries by a straight line. Later, Imperial Japan
was added to the axis, geometry be damned.
It turns out that just as Spanish has two kinds of hacha, with the sense
of axe or hatchet prevailing, so English has had two words
axe (also spelled ax), the same sense now prevailing. The other
sense of ax was of axle or axis, derived from a common Germanic root
(cf. modern German Achse) related through
Indo-European to Greek áxôn and
Latin axis.
- Hackgold
- See Hacksilber.
- Hacksilber
- Randomly shaped pieces of silver, used as
currency in the Near East for thousands of years before the advent and rapid
adoption of coinage. There have been no Hacksilber finds in Greece, but
a hoard of Hackgold, dating to the 8th c. BCE, was excavated in Eretria
in the late 1970's.
(That Erétria
was an Ionian colony on the Aegean island of Euboea, near the Attic coast.
There is also a nearby modern town of a few thousands by the same name, and
another modern Eretria on the Greek mainland, in western Magnesia. The
similarity of the name Eretria to that of the country of Eritrea is very
probably coincidental. The latter is derived from the Latin name of the body of water it has a coast on:
Mare erythraeum, literally `Red Sea.')
But to get back to silver, that English-v/German-b correspondence works
reasonably well for noninitial consonants, incidentally. In addition to
silver/Silber, one can adduce
carve/kerben,
cleave/klieben,
fever/Feber,
give/geben,
have/haben,
heave/heben,
knave/Knabe,
live/leben,
love/lieben,
over/über,
seven/sieben,
and
starve/sterben [follow link for discussion of
a semantic shift here],
etc.
Typically, this works for cognates going back to proto-Germanic. In many
cases one can no longer make the correspondence because a necessary cognate is
missing on one side or the other. For example, leave had cognates in
High Germanic dialects at least up to 1000 AD (some may yet survive in local
dialects), but apparently no straightforward reflex of these survived into
Modern German. A cognate verb bleiben (`stay, remain, be left') did
survive. This is a contracted (``syncopated'') form of a compound that would
otherwise be written beleiben. English had cognates belive and
beleave, but they petered out of use in the fifteenth century.
The same correspondence holds for loans from a third language, if they occurred
early enough. The only such example above is fever, from the Latin
febris.

- hageru
- The standard transliteration (in both Hepburn and Ministry of Education
schemes) of two distinct but homophonous Japanese verbs. One means `go bald'
and the other means `come off, peel off.' I count this an instance of a
situation that is surprisingly frequent in Japanese: homophones with apparently
related meanings, written with evidently unrelated
kanji (and hence presumably based on unrelated
morphemes). Native Japanese speakers don't find these coincidences surprising;
their language has a high frequency of homophones generally, and some fraction
of the time one must expect such coincidences. But look:
sôzô means `creativity.' A different word
sôzô, written with a different pair of kanji, means
`imagination.' This just happened by accident? Sure.
Sometimes there is only a one-kanji difference, but one is still suspicious.
For example, there is a two-kanji word fujin that means `woman, lady.'
With a different first kanji that also happens to be pronounced fu, one
gets a different word fujin that means `wife.' (The common final
element -jin means `person,' as in gaijin.) If the second word
fujin corresponded closely in meaning to the English word wife,
then a famous punchline would go something like ``that was no fujin,
that was my fujin! As it happens, this wouldn't work because
fujin only refers to the wife of the speaker or the writer. The wife of
the speaker is referred to by a sort of first-person version of the word:
kanai. This is not the only instance in Japanese where the choice of
noun carries the sort of person information that
pronouns and verbs carry in European and Semitic languages. Japanese verbs are
not conjugated for person or number, and Japanese personal pronouns are often
omitted. (Also, it is perfectly acceptable in Japanese conversation to use
one's own name instead of a personal pronoun equivalent to I or me [typically
watashi].)
Often you have to suspect neologistic malice. It strikes me as needlessly
inconvenient that the word for comet and the name of the planet Mercury are
both suisei -- a coincidence because the sui morphemes arise from
two unrelated kanji. I suspect that a certain element of mischievous
choice is involved. It's hard not to suspect that
there isn't some coy significance in the fact that fusai is the
pronunciation of totally unrelated words meaning `married couple' and `debt.'
When you go beyond exact homophones to approximate homophones and similar
words, the list of suspicious coincidences grows. Shujin, for example,
has the meanings of `owner, master [or mistress, as the female form of
master], husband.' Don't think too hard about that, but consider that
with a different initial kanji one has shûjin, which means
`prisoner.'
- hagn, HAGN

- hagwon

- HAI
- Health Action International. According to HAIAP's page (visited in 2005) for HAI, it is ``an informal network of
around hundred and sixty member organizations and individuals focusing on
health, development, consumer and other public interests in over seventy
countries.
Founded in Geneva in 1981, HAI's objectives lie on promoting rational use of
drugs and ensuring regular availability of quality healthcare and safe and
effective essential medicines of good quality to all at affordable prices.
With four coordinating offices in Africa,
Europe, Latin
America and the Asia Pacific, HAI carries out its work through advocacy,
research, education, action campaigns and dialogue.''
If HAI is pronounced as ``high'' then it is a homophone of a Hebrew word
meaning `life.' (That word is typically transliterated chai, but in
European languages
different aitch sounds are usually allophones with disjoint distribution.) Hai is also the standard transliteration of a
Japanese word that means `yes.' (A lot of the time it really just means `I'm
listening' -- sort of like ``yes, dear'' but for use in all social situations.)
A more informal version is ihai. And be careful how you answer a
question, if the question states a negative proposition.
- HAI
- Helicopter Association International.
- HAI
- Housing Affordability Index. The best-known HAI in the US is one computed
and reported monthly by the National
Association of Realtors (NAR) and
described here.
At least some state associations of realtors compute similar indices for their
states. Note the word ``similar.''
A HAI is defined in terms of the ``required income to qualify for a
conventional loan'' on a home purchased at the median price of houses being
sold. The ``conventional loan'' is a 30-year (I think) fixed-rate mortgage
with a 20% down payment. The mortgage payment is computed using the
``prevailing mortgage interest rate'' reported by the Federal Housing Finance
Board (FHFB) and by
HSH Associates of Butler, N.J., for loans
closed on existing homes. The ``required income'' is defined as 25% of gross
income. The affordability index is defined as the ratio of median income to
that ``required income'' for a mortgage on the median-price house. If you
prefer, the index is one quarter of the median monthly household income divided
by the monthly mortgage payment on a median-price house.
This is a very sensible measure of affordability, but its downfall is that
people do not, at least collectively, behave very sensibly. If the median
household or future household lived sensibly within its means and only sought a
mortgage once it had saved up the 20% down payment, then it would indeed find
ownership of a median-price home affordable if the HAI were high. (But rather
higher than 1.0, perhaps, if they happen to pay taxes.) Since the savings rate
in the US was negative for much of the housing boom, the median household
probably did not save the necessary down payment.
One may defend the HAI by saying that, of course, it only measures the
affordability of housing for sensible people who save up for a traditional
loan. They may have the median income, even if they are not typical. (Hey:
the median family doesn't buy a new house every month either!) That might be
defending the indefensible, but I would like to go a little further and defend
the fool who went ahead and bought a house he wasn't ready to afford, by taking
out a nontraditional mortgage. Maybe he was a sensible individual living in an
unsensible world.
Our poor fool would have noticed that the down-payment target was moving, and
that his savings were not moving as fast as the target. At that rate, he'd
never be able to own a home; he'd just be stuck on a treadmill paying
increasing rent. Then it came to him: the only way to save up for a home was
to make a high-return investment in... real estate! Would the numbers work?
Well, he wasn't, like, a math whiz or anything, but the loan officer at the
bank seemed eager for his business -- that's not hard to interpret!

- hakwon
- A common variant spelling of hagwon in
English.
Although both /g/ and /k/ sounds occur in Korean, the distinction is not
phonemic. That is, they are allophones. The emic
perspective is probably best understood in terms of Hangul, the featural script
of Korean -- the standard script. Hangul is written in blocks designed to
resemble Chinese Han characters (logographs), but each such syllable block can
be analyzed in terms of component characters called jama, which may be
deformed somewhat to fit the block. (I could have just called the jama
``letters'' and let it go at that, but I figured I'd make trouble instead.)
The system is called featural because the forms of the jama illustrate
schematically (or at least try to) major features in the articulation of the
sounds they represent. Thus, the symbol for g/k is shaped like a capital Greek
gamma (but facing left) not for sentimental xenophilic reasons, but to
represent the shape that the tongue makes, viewed from the side, in the
articulation of a velar consonant. An extra line is added to this symbol to
indicate aspiration and represent the related affricate /kh/, and a
doubled form is used for a tensed or faucal version of the sound.
The velar stop takes voicing by assimilation, and so its sound in hagwon
is indeed /g/. There are a variety of different Romanizations
of Korean, with varying degrees and domains of acceptance de jure or
de facto. Some use g to indicate voicing of the k/g character. Some
use g preferentially for the k/g, even in cases where it is unvoiced, in order
to save k (possibly with kk) for the other velars. In the latter case,
hakwon is the appropriate Romanization.

true of Harry, also a nickname form of Harold. In consequence, Hal, Harry,

thus has the situation of Harry being used as a nickname for someone whose
given name is Hal, which might seem slightly odd to a foreigner named Peggy.

In Clarke's book, it was a 1997 model. The commemorations were held in 1997.
[Clarke came out with a new book, 3001: The Final Odyssey.
Cervantes was thinking of just this when he observed ``Nunca segundas
partes fueron buenas.''
(Loosely: `Never were sequels any good.') However, as Arthur Clarke himself
admits (NYTimes, 1997.04.01, p. B1), he likes
attention. If he hadn't moved
to Sri Lanka, we might have been spared another best seller, although we also
would not have Kubrick's precious remark: ``Arthur Clarke? Isn't he a nut who
lives in a tree in India someplace?'']
There's a pentium

- Halaka
- Language spoken by the Halaka People. This nation has no internationally
recognized, politically independent homeland, and its precise origin is
obscure, but it is dispersed throughout the world, and increasingly
westernized. Indeed, native speakers are extremely rare.
The Halaka language has virtually no productive inflections. Although its
phonology suggests a Slavic influence, Halaka is not an Indo-European (IE) language. Thus, the resemblance of its name to the
Hindi word halka, (`lightweight') is probably accidental. [Note,
however, that the first alphabetic writing system for Sanskrit, believed to
have arisen from an Aramaic alphabet, was
almost a syllabary, with the default that all consonants were followed by a
vowel a : halka --> halaka (a common current pronunciation in the
southern, Dravidian-speaking regions of India).
Hindi is in the Sanskrit subfamily of IE languages.] There is also no apparent
relation with the Hebrew halakha, `the path,' which conventionally
refers to the totality of oral and written Jewish law. As the only extant
member of its language family (Obnac), Halaka may in fact be called a
language isolate.
Today, among an estimated 34 million i speakers worldwide (1990), there is
already 85% literacy in the Romanized (i.e., Latin-character-based)
orthography. A valuable and comprehensive Halaka <-->
English translation dictionary was once available online, but Scott
Bordelon apparently decided that the joke was getting old. It took a while for
the dictionary to fade from search engine indices. Bordelon also submitted
a translation of
``Silent Night, Holy Night'' into Halaka to a site that collects such
things. It seems from the text that the grammar, idioms, and semantic fields
of corresponding words of Halaka are identical to those of English, except that
the word ``the'' is elided in translation. A great convenience, but very hard
to rhyme.
I can't take it anymore! I confess! It's
lies, all lies! But that translation dictionary was pretty good.
I can't remember certainly any more, but I think you could input any English
word or nonword and it would spit out an answer. (The same answer for a given
input each time.) And the output Halaka words looked wordlike -- no
three-consonant clusters, for example. So there must have been some general
translation algorithm, but it was hash-like yet constrained.
There, I feel much better now. Please resume your suspension of disbelief.
You know, the path thing is a widespread pretense of religions. Just as in
Judaism the law is called the way (halakha), so Christianity has John
14:6 (``I am the way, the truth, and the life''). Path imagery has been
popular in Christianity, hence special use of words meaning traveler. (See,
for one example, the book Pilgrim's Progress described at the V.F. entry.) Various actual pilgrimages are optional
elements of Christian devotion, and in Islam a pilgrimage to Mecca is the
obligation of every Muslim who can afford it. The English word Taoism
comes from tao or dao, meaning `way,' which stands for the basic,
eternal principle of the universe
that transcends reality and is the source of being, non-being, and change.
That would appear to about cover it. Buddhism has two major schools; the
extant one is called Mahayana, Sanskrit for `great vehicle.' Followers of
Mahayana dubbed the other school Hinayana, `lesser vehicle.'

It's back! The Halaka-English Global
Translator is the index page of <halaka-dict.appspot.com>. Well,
actually, it seems to have an entirely different vocabulary and phonology, and
now there are inflections and a flag, but to judge from the about page,
it's just as real and authentic as before. Gerpun!
This translator doesn't attempt to translate nonwords or regular plurals of
English, to judge by a few experiments. So
basically it just seems to be a
pseudorandom mapping gated through a large English wordlist.
I think there might be some tweaking of individual translations. I suppose
this is handled by running the map in advance and prestoring -- and tweaking --
the results in a database, but maybe it's done by exception-handling and most
Halaka translations are coined for you by an invertible algorithm in real
time. Of relevance is the fact that the translator tool is not perfectly
invertible. In particular, Halaka
na maps to putative English kil, but English kil is left
untranslated into Halaka (possibly because it's the proper noun for a
Korean car maker).

- half-integer
- [Dear reader: this entry is a bit of a long-term project under construction,
accidentally published prematurely. Sorry about that. It doesn't appear to
be much less intelligible now than it will eventually be or was before, so I'll
just let it all hang out.]
Half an odd integer. A physicists' term for the quantum numbers of various
angular-momentum-like observables. Obviously, half an even integer is also an
integer. The point is to distinguish the numbers that are half-integers but
not integers. (These are associated with fermions, q.v.)
There are a number of important angular-momentum-like observables, to be
discussed below roughly in order of increasing abstraction. This material
is normally covered at various different stages in a physics curriculum, so
many readers will find that the going gets unfamiliar or tough rather quickly.
A system with a well-defined angular momentum or algebraically similar
observable will have a ``good quantum number'' describing it. The most
commonly discussed observables of this kind (with the usual variable
designation in parenthesis) are
- orbital angular momentum (L)
- This is the ordinary angular momentum defined analogously
with classical angular momentum in terms of position and
momentum operators. The classical angular momentum vector
L for a rigid body points along the instantaneous axis
of rotation (direction according to right-hand rule). The
rotation degree of freedom is bounded (I mean -- what goes
around comes around) and, more or less as a consequence, the
associated observables are discretely quantized. (I.e.
the quantum-mechanical eigenstates of the operator do not take
a continuum of eigenvalues. In fact, the spectrum (the set of
eigenvalues) has a simple form: the possible eigenvalues of
L2 are L(L+1) in the natural units (aitch-bar
squared), where L is a positive integer. (Please attend this
fact: boldface L here represents a vector. In classical
mechanics, italic L its scalar magnitude. In the same
way, p is ordinary momentum and p is its
magnitude. In going from classical to quantum mechanics, one
takes the vectors p and L into vector operators.
Because it is an observable, it is certainly possible to
discuss its magnitude -- we effectively just did so in the
sentence preceding this parenthetical. However, it is
inconvenient to use L in the classical way, because of
confusion with the quantum number L. (In atomic
physics, it is often written with a lower-case l.)
The vector components of L are noncommuting: rotation
about one axis followed by rotation about a different axis is
not equivalent to the same operations taken in the reverse
order. Noncommuting variables cannot be in simultaneous
eigenstates, ... you know, I think I may be losing the people
who forgot what they learned in Quantum 101, sorry ... so
angular
momentum eigenstates are further classified by only a single
component, usually chosen as along the z axis. In natural
units, the allowed values of this angular momentum component
(typically labeled lz or
ml) are the integers between -L and +L
inclusive (loosely: -L, -L+1, ..., L-1, L). Hence, for an
orbital angular-momentum quantum number L, there are 2L+1
states.
This is a good point to return to the idea of ``good''
quantum numbers. Obviously this is a quantum notion, but it is
related to symmetry, and symmetry is a more general notion.
We say that a system is spherically symmetric if the equations
that describe it look the same in any direction. A spherically
symmetric mechanical system can rotate in any direction.
Nothing can slow or speed such a rotation, since that force
would require a description that was not spherically symmetric.
(Believe me, this is a lot easier to say with equations than
words.) Intuitively, something that rotates faster has more
energy. In fact, for simple mechanical systems, [okay, looks
like this part wasn't finished]
- intrinsic spin (S)
- This is always well-defined for any elementary particle.
The original proposal of intrinsic spin was made by two
graduate students, Goudsmit and Uhlenbeck, who proposed that
an internal spin variable for the electron would explain some
degeneracy anomalies (i.e., there seemed to be twice
as many single-electron states as one would expect; kinda
important if you want chemistry to work out). In order for
this idea to work, there would have to be only two
intrinsic-spin states. You can see (correctly) using the
formula for orbital angular momentum that 2-fold degeneracy
requires 2 = 2S+1 or S = 1/2. There is
no way to derive a half-integer value from an angular momentum
that generalizes classical angular momentum (as above).
Goudsmit and Uhlenbeck went back to their advisor and said they
had second thoughts about their idea and preferred not to
publish. He told them it was too late, he'd already sent
their manuscript off. In those days, journal reviewers were
not so nitpicky either, and the paper went to press. Their
advisor (I forget who) consoled them: they were young -- they
had the right to publish something crazy. As soon as the paper
appeared, H. A. Lorentz pointed out that given the known
bounds on the radius of the electron, the proposed value of
spin represented an angular momentum so high that the surface
of the electron would have to be moving faster than the speed
of light (an obvious no-no).
There are other classical-picture objections, and the basic
answer to them all today is: spin is an intrinsically
quantum-mechanical quantity that happens to share numerous
properties (including its general algebraic structure and a
proportionality to magnetic moment) with orbital angular
momentum, but does not arise from particle motion that has a
classical analogue. It is handy to visualize it as the spin of
a particle, but strictly speaking elementary particles have no
geometric extent and don't spin. (I mean: in the underlying
description, elementary particles are points. The real
particles they describe, of course, cannot be perfectly
localized -- this follows from the uncertainty relations. The
picture gets trickier with string theory. String theories are
formulated in more than the usual three space dimensions, but
the excess dimensions are curled up very tight -- the distance
that anything can move in those other directions is
preposterously short, and when you move that far, you've just
circled back to where you started. Anyway, in these theories
fundamental particles are described by strings -- closed loops,
in fact. The particles still have at least a codimensionality
of three in the higher-dimensional space, so on any human scale
it is reasonable to call them point-like.)
There are now many particles (fermions) known with spins (S
values) of 3/2, 5/2, and higher. However, so far these
are all composite particles or excited states of other
lower-mass, more stable particles that have spin 1/2. Spin-S
particles have states of well-defined z-component spin
(labeled sz or ms) with
spin angular momentum values from -S to +S. (I.e.,
-1/2 and +1/2 for spin-1/2; -3/2, -1/2, +1/2, +3/2 for spin-3/2,
etc.) [I ought to talk here about Regge analysis, a great fad
around 1960. On second thought: no I shouldn't.] The term
half-integer normally modifies spin, which is to say
total spin quantum-number rather than a component
(``ess-sub-zee''). Therefore, in practice, the
half-odd integer it refers to is positive.
- Isospin (I)
- Contracted from the older name for this concept: isotopic
spin. As an aside here, I should mention that isospin, like
angular momentum and all the rest
In outline, the idea behind this is simple: protons and
neutrons are particles with similar mass, and since mass is energy, they have the
same energy. Now as noted above, rotation symmetries yield
finite numbers of degenerate states, corresponding to distinct
values of the z component of angular momentum. Introducing a
completely
inventing a new
spin-like algebras yield finite numbers of degenerate The idea had
been around even before relativity, that particles are, as we
would say now, ``excitations of the vacuum.''

- There's more (intrinsic spin of a collection of particles,
total angular momentum, etc.), but that's for another
day.
- halo
- `I breathe' in Latin. The infinitive is
halare. [That's mildly amusing in
Spanish, where halar
(< French haler; I haven't checked
beyond that) means `to pull.']
The Latin verb is source of English words like halo and exhale. The Latin noun
form halitus (`breath') is used medically and is identified as the basis
of the word halitosis. The conversion of the u to o presumably is a
feint in the direction of creating a Greek noun, but I'm not buying it: the
ending `-sis' is Greek and the root is Latin, so halitosis is a
barbarism. I'm sure we all agree.
- halo
- In classical scattering, the differential scattering cross section can be
computed as b db/d(cos(θ)), where b is the impact parameter and θ
is the scattering angle. If b is not a function of θ -- i.e., if
some angles occur for more than one value of impact parameter -- then the
differential cross section is computed from all the relevant derivative
expressions like the above, summed. Since θ is normally a smooth
function of b, when this occurs there will be a turning point -- an angle where
the above derivative expression diverges. That kind of (integrable, of course)
divergence is called rainbow scattering. Another kind of divergence occurs
when the scattering angle crosses zero at finite b. This causes a brilliant
forward scattering called a halo.
- halo
- When an atom or nucleus has nearly saturated its bonding, it often can bind
one or a few last particles extremely weakly, in low-angular-momentum state(s).
These few weakly bound particles are also called a halo.
The trivial nuclear example is deuterium, which can be regarded as a proton
nucleus with a neutron halo
(D = 2H = 1H + n). This
sounds silly on its face: you'd figure that the neutron-proton separation would
determine the only sensible definition of what is `inside' the nucleus, so that
neither nucleon could be outside of it, on average. However, the
rms internucleon distance is an astounding
4.4 fm, so most of the time the nucleons are outside the range of their
interaction. Effectively, one should regard halo nuclei as those with some
nucleons that spend much of their time more than about a
fermi (1 fm) away from any other nucleons. The
large average separation is a natural consequence of the just-bound nature of
the deuteron. [The scattering-length concept makes this extremely explicit.]
A more intuitive example is 11Li, which looks like
9Li + 2n. [The numbers preceding `Li' should be
superscripted. Upgrade your browser or don't complain if they're not. The
number in this position next to the chemical symbol for an element represents
its atomic mass number A -- the number of nucleons
in the nucleus.] The core 9Li has its four protons and five
neutrons in a radius of 2.5 fm. The two-neutron cloud in 11Li has a
radius of 7 fm.
I think that 11Li marked the ``modern discovery'' of halo nuclei by
B. M. Young, et al., reported in Phys. Rev. Lett. vol. 71.
Afterwards, it became clear that the surprisingly large branching ratio for E1
decay of 11Be, reported by D. J. Millener, et al. Phys.
Rev. C 28, 497 (1983), could be explained simply in terms of a
neutron halo.
- HALO
- High-Altitude, Low-Opening. I.e., high-altitude jump (15K feet),
low-altitude chute-opening. Paratrooper strategy for minimizing
vulnerability in jump behind enemy lines.
- HALO
- High-Amount LockOut. A POS term meaning
maximum allowed price. HALO's are defined to prevent the most eye-popping
errors by operators (those who key in POS system data).
- haloid
- A word constructed from the Greek roots hals (`salt') and
-oeidês (`form'). The word was coined by Berzelius to describe
any simple metal halide salt.
The key salt in old black-and-white film was silver iodide, and so one film
manufacturer in Rochester called itself Haloid. It later became Xerox.
Yes, yes, the city of Halle in Germany got its name from salt mines there.
- halogen
- An element in the penultimate column of the periodic table (the seventh
column in the compact form of Mendeleev's original table). This is the group
next to the noble gases. Going down the periodic table, the halogens are
Fluorine (F), Chlorine (Cl),
Bromine (Br), Iodine (I),
and Astatine (At). (As a practical matter that's
about it, but artificial elements created in miniscule quantities are crawling
along the next period with increasing atomic number, so it's foreseeable that
a new and practically irrelevant halogen will be named.
As is common in many element groups, the lightest element is a bit of an
outlier. Hydrofluoric acid, although it is extremely dangerous and corrosive,
is not the strong acid that hydrochloric and hydrobromic acids are at the same
concentrations.
Sometimes hydrogen is given two locations on the periodic table: its usual
place at the beginning (upper left corner) and also the spot just left of
helium, which is to say just above fluorine in the column of halogens. This
makes an obvious sort of ``electronic'' [atomic-level] sense: there is a single
unoccupied state in the highest (and only) occupied level (1s). It also makes
a bit of chemical sense, as there are hydrides -- simple compounds in which
hydrogen has valence -1 like a halogen. Just don't call it a halogen. (And
normally, expect it to have valence +1.)
- halogen lamps
- Halogen lamps are technically better known as halogen-cycle lamps. Quartz,
quartz-iodine, and tungsten-halogen lamps are other names used.
Halogen lamps are incandescent lamps that use a halogen fill gas, usually iodine or bromine, and (as
is essentially universal for incandescent lamps) tungsten filaments. Tungsten
atoms evaporated from the filament react with the fill gas to form tungsten
halide (i.e., tungsten iodide, tungsten bromide, etc.). This compound
does not stick well to glass, but tungsten halide molecules adsorbed on
tungsten metal react to deposit tungsten and evolve halogen gas. These facts
result in the capture and eventual redeposition of tungsten on the filament.
This is called the halogen cycle, and by reducing the effective rate of metal
evaporation, it reduces the principal mechanism of lamp aging. (When a halogen
lamp is operated at low power, tungsten halide accumulates on the bulb surface.
Operation at full power re-evaporates the condensate, clearing the glass and
regenerating the filament.)
During operation, the density of the vapor must be high enough to assure that
the mean free path of a tungsten atom is much less than the distance between
filament and bulb. This can require fill gas that is close to atmospheric
pressure. At atmospheric pressure, the boiling point of bromine is
58.8°C, so bromine fill gas condenses as a fluid when the lamp is
cold. (The Br melting point is -7.27°C.) Iodine has boiling and melting
points of 184.35°C and 113.5°C. In a small quartz lamp I used to
have, a thin brownish film and a hardened droplet or two would be left on the
inside surface of the lamp after it cooled, and would slowly vaporize as it
heated.
(Normally, incandescent bulbs have nitrogen, argon, or a mix as fill gas, at a
low pressure that rises to about one atmosphere at normal operating
temperature. Lamps of less than 40 watts typically are just evacuated.)
A little point that was elided above is that while tungsten halides do not
react and bond to glass, they may simply condense. Hence, halogen lamps must
be operated with the interior of the bulb at 500 degrees C or above. (This is
just one very good reason to avoid touching a halogen lamp with your bare
fingers.) For a long time, halogen lamps used quartz bulbs because quartz
glass was the only kind that had the necessary high-temperature strength.
(Nowadays there are some alternate glasses in use.)
At the high temperatures reached by quartz bulbs, some skin oils can penetrate
and degrade the glass, making it porous, admitting air, and resulting in early
failure. Don't let this happen. If you touch the quartz when it is cold, then
before turning it on, clean it with a solvent such as lighter fluid. (I
love this recommendation. Be sure to dry it off and put anything flammable
away before you turn the lamp back on.) If you touch the quartz when it is
hot, just scream.
- halo orbit
- In astronomy, an orbit ``around'' one of the
Lagrange points formed by two objects,
rather than around a single object. Halo orbits exist around the L1, L2, and
L3 points; like these Lagrange points themselves, they are unstable, but a
space probe can maintain the halo orbit for years with a small expenditure of
fuel. A number of probes, such as SOHO, have
used halo orbits around the Sun-Earth L1 point; at the L1 point itself, they
would be much harder to communicate with due to the Sun being in line.
In the preceding paragraph, the word ``around'' is in scare quotes because the
Lagrange point is not exactly at the middle of a halo orbit. If one switches
to a rotating frame in which the two large-mass objects are stationary, then
the halo orbits do periodically go around the axis connecting the two. And if
the orbit is tight, then it is close to its corresponding Lagrange point. As
the size of the halo orbit increases (as measured, say, by its average radius
about the axis in this frame), its average position along the axis changes.
- HALT
- Highly Accelerated Lift Test.
- HALT
- Hot-Air-Leveled Tin. In electronic interconnect fabrication, HALT refers
to the final step in the process of tin-coating copper strips. The copper
strips are passed through a molten bath of tin (Sn).
The tin wets the surface of the copper (Cu), and as
the strip emerges from the bath the thickness of its tin coating is controlled
by an air knife. The main alternative to HALT is
HTD (hot tin dip). In HTD, the tin thickness is
controlled by a mechanical wiper. HALT was introduced in around 1985; HTD is
the older process, but I'm not sure exactly when it was introduced.
The melting point of tin is 232 °C. This is around the softening
temperature of copper (m.p. 1083 °C), but the tinning is done in a quick
reel-to-reel process, so the copper is hardly deformed. However, a thin layer
of copper-tin intermetallic compound (primarily Cu6Sn5)
forms between the metals.
- ham
- Amateur Radio Operator. The
University of Arkansas at Little Rock's Amateur Radio Club has a
useful Home Page, with a
callsign database server. We (SBF) also offer a
list of Q-signs. The use of ``ham'' for amateur radio operator stems from
the earlier use of ``ham'' for a bad actor.
- ham
- An excessively emotive actor. Or more generally an amateurish or poor
actor. The etymology is in the next entry.
- ham
- The English word ham is descended from a proto-IE root meaning
`crooked.' The earliest recorded senses in Old English, starting around 1000
AD, are for the back of a man's knee, hollow of the knee, etc. In the middle
of the 16th century its sense was drifting upward, to the back of the thigh or
to the thigh and buttock together. [For linguistic thoughts on the buttock,
see fanny.] These senses of the word ham are
not altogether obsolete, but they are now perhaps most often encountered in the
fused compound noun hamstring, for either of
the tendons that forms the back of the knee and attaches to the muscles of the
thigh.
At least by the beginning of the 17th century, ham also referred to the
hock of a quadruped. Now, it is obvious from an evolutionary standpoint, and
even from any coherent anatomical viewpoint, that the hock of a quadruped like
a hog, horse, or dog corresponds to the heel of the human foot. Hence, what is
called the ``hamstring'' in these animals corresponds to the Achilles tendon in
the human. However, these animals walk essentially on what correspond to the
toes of the human foot. (Or on what corresponds to what is left of it.
Although the ur-mammals had five digits at the end of each of their four limbs,
most mammals today -- excepting primates and elephants -- have fewer. The
horse went from three toes to one relatively recently, I think.)
By the middle of the 17th century, ham referred to the thigh of a
slaughtered animal, especially cured hog thigh (salted and smoked, or salted
and just dried), and that is the most common sense of ham now, of
course. ``Ham hocks,'' a feature (or a bug) of soul food, are simply hog
hocks.
Ham as a term for an overacting performer or a poor actor generally evidently
arose as a short form of hamfatter, from a popular minstrel-show song
originally in ``The Ham-fat Man'' (1863). By an association of amateurishness
in acting with ``amateur'' in general (and there is the phonetic similarity),
the word ham came to be used for ``amateur radio operator.''
I've come across a number of jokes that turn on an English-speaker in a
restaurant in France asking for jam and getting ham
(jambon in French). This never happened
to me. Frankly, when I was in southern France I found that a lot of the
restaurant help and shop clerks were Spaniards.
The Spanish word
jamón (also meaning `ham') sounds
closer to the English because the j was devoiced into an aitch sound half a
millennium ago, but the word was obviously (yeah, there's evidence) borrowed
from the French. The etymological trail of these j-words disappears back in
Vulgar Latin, and it might or might not be related to the English word. And on
the subject of vulgar language, Spanish has a slang term jamona that
might be translated loosely as `juicy woman.'
- HAM, Ham
- A common abbreviation for Shakespeare's play Hamlet, Prince of
Denmark. IMHO it's cool that this common abbreviation coincides with the
common term for the kind of character who could chew up the scenery --
especially in the title role. (The etymology of this ham is explained
not far above.)
One piece of evidence put forward by Stratfordians, though not the strongest,
is that William Shakespeare named his son Hamnet (sic). [Stratfordians
are those who hold the view that the plays attributed to William Shakespeare
were written by the man named William Shakespeare, of Stratford-upon-Avon.]
- Ham
- A son of Noah. The other two were Japheth and Shem. They already had
wives before the flood. For a long time, lasting into the nineteenth century,
Christians reasoned that since all humans were descended from the three
brothers, that the races of mankind could be correlated with that descent.

`Islamic Resistance Movement.' (Traditional semitic alphabets are essentially
consonantal. In Hebrew and, I presume, in Arabic too, acronyms are based only
on these consonants, with the vowels usually a sounds or based on a parallel
with another word. One would expect the ``silent'' stop consonants at the
beginning of the definite articles al to be ignored. For what it's
worth, it looks like the alif at the beginning of the word Islamiyyah
was also incorporated.
Hamas was founded in 1987, at the beginning of the first intifada or
`uprising' against Israel. Hamas vows never (see

to accept the existence of a Jewish state in the Middle East, and engages in
terrorism against Israelis essentially anywhere. It won a majority of seats

- Handbook for Scholars, A
- A little volume by Mary-Claire van Leunen. The revised edition, from OUP,
was published in 1992. Van Leunen takes a very unhelpful attitude regarding
the indication of changes in quotations. She insists that ellipses should only
be used ``for omission from the middle of a quotation, not from either end.''
Wrong. The absence of an ellipsis at the end of the preceding quote allows you
the reader to infer, correctly, that I have quoted to the end of one of her
sentences. Conversely, an ellipsis at the end of a quote indicates that more
material remains in the sentence, as in ``omission from the middle of a
quotation....'' A scholar should care about the difference, and it is no fault to be informative.
Similarly, she condemns bracketing case changes. But when I quote her writing
``bracketing such changes looks not punctilious but weird,'' you know that
this is only part of a sentence. Had it been the entire sentence my quotation
of it should have begun ``[b]racketing such changes....''
She concludes, ``[p]roceed blithely.'' Don't.

- It's training to help you increase sexual harassment, but it doesn't work the way
you'd think. Instead of increasing it directly, by teaching you how to do
it, it does so indirectly, by discovering it where you didn't suspect it was.
In fact, by stigmatizing innocent behavior and getting people fired for having
the misfortune to share employment with prickly scolds, it might be thought of
as training in a kind of harassment. That kind of harassment, however, is
not officially a bad thing.

- hardly
- Currently, this adverb is used primarily in senses like `scarcely' or
`almost not' or kaum (in German).
In origin, however, the word (heardlice in Old English) meant `harshly'
or `bravely.' That is, it meant `in a hard manner' with an older sense of
hard: `bold' or `forceful.' (The modern word hard may be said to
preserve the ``passive'' senses of its etymon.) Use of the original sense of
the adverb has been in a long-term decline; a more common expression of the
idea is ``with difficulty.'' This sense still took pride of place in the
hardly entries
of Noah Webster's
American Dictionary of the English Language (1828) and
of
Webster's Revised Unabridged Dictionary (G & C. Merriam Co., 1913, edited
by Noah Porter).
The `with difficulty' sense of hardly is hardly common at all. In fact,
it's not hardly common: it's just plain rare. But it's not unknown,
though I'm not sure if it's hardly unknown. Anyway, here's part of a paragraph
that uses hardly in two different senses. In the second instance the
different senses of the word are almost opposite, and the context is needed to
make clear which sense makes sense.
... In the last quarter of the seventeenth century Cartesian science was
indeed expounded in some of the colleges of France, and less widely
elsewhere, but dissemination of the thought of Galileo, of Bacon, and of
the exponents of the mechanical philosophy owed little to university
courses. Occasional examples of a university teacher having a decided
influence upon a circle of pupils--as was the case with John Wilkins at
Wadham College, Oxford, and Isaac Barrow at Trinity,
Cambridge--hardly vitiate the general conclusion that the activities
of various societies, books, and journals were far more potent vehicles of
proselytization, which is supported by many personal biographies. However
stimulating the exceptional teacher, formal courses were commonly
conservative and pedestrian: it is curious to note that the two greatest
scientists of the age who were also professors, Galileo and Newton, seem to
hav been singularly unremarkable in their public instruction. If the
universities could produce scholars, they were ill-adapted to turning out
scientists; the scientist had to train himself. Many who accomplished this
transition regarded it, indeed, as a revulsion from the ordinary conception
of scholarship. The learning they genuinely prized, in their own
scientific disciplines, they had hardly won for themselves. It
would surely be absurd to argue that Newton was less a self-made
scientist than Huyghens, or Malpighi than Leeuwenhoek, because the former
had attended a university and the latter had not.

Craftsman in the Scientific Revolution,'' in Critical Problems in the

- hard water
- Water with a high concentration of dissolved ions that precipitate soap.
Almost always, that's calcium ion. ``High concentration'' means high compared
to whatever one is used to -- you notice the difference immediately in the
shower. In absolute terms, a convenient mark is
100 mg/l CaCO3 (calcium carbonate). It's worth noting
that this description is nominal: one computes the ``dissolved
CaCO3'' from the measured concentration of Ca. What is really in solution is mostly Ca2+
and HCO3- (bicarbonate) in an alkaline
(OH--rich) solution (see pOH entry).
(There's also a relatively small concentration of dissolved
CO3= ion. I actually had a student ask me once what the
superscripted equals sign meant. It's a doubled negative sign. I might have
written CO32- equivalently.)
Detergent and soap molecules all have basically the same structure: NaR, where
R is a long-chain organic molecule. In traditional soap, the long chain is a
fatty acid. (Explanation at the saponification entry. Detergent is usually sodium lauryl sulfate, where lauryl-
is a twelve-carbon carbon chain extracted from plants, and the sulfate group on
the end of the chain bonds to the sodium.
In the presence of nonpolar dirt, the nonpolar end of a soap molecule buries
itself in the dirt and the polar Na+ sticks out where it can
dissolve in water. In soapy water, microscopic droplets of dirt accumulate
a highly polar surface this way, enabling them to dissolve in water and rinse
down the drain.
Calcium ion interferes with this process through the following competing
reaction:
Ca2+ + 2NaR --> 2Na+ + CaR2 .
The causes problems both sterically and through ordinary solubility chemistry:
- Sterically, the carbon chains tend to surround the calcium with nonpolar
dirt in such a way that it has less exposure to the water it's supposed to
dissolve in.
- In any case, calcium ion is less soluble in water.
The upshot is: soap scum. The problem is less bad with detergent than with
ordinary soap. Clothes washed in hard water may develop indelible spots.
Another effect of hard water is to prevent lathering. Lathering is simply the
formation of small soap bubbles, and ``soap bubbles'' are really just water
bubbles. The role of soap is only to reduce the surface tension of water so
the water can form the stable thin-film surface of the bubble. Soap converted
by reaction with calcium just doesn't have the same surfactant effect.
Hard water arises because water supplies often come from underground water
sources -- aquifers. An extremely common aquifer material is limestone,
which consists mostly of calcium carbonate. That's the reason hard water comes
not only with high calcium concentration but high carbonate concentration.
That carbonate is associated with another hard-water problem: precipitation of
calcium carbonate. Nowadays, people notice this first in their teapots: over
time, carbonate rings form around the level where the water boils. It's not
bad for you and you can't taste it (although you can certainly imagine that you
can). It does look bad, though, and many people throw away perfectly good
teapots just because they've accumulated an unsightly ring.
DON'T THROW IT AWAY, YOU IDIOT!!!
What you do is, fill the teapot with water above the ring level, and add lemon
juice or vinegar or some other acid. (I suppose any cola would do too. Those
are acidified by phosphoric acid, but the sour taste of the acid is entirely
masked by the sweetness.) Cook it a little bit and the acid will dissolve out
the carbonate. Throw out that water now and you have a clean teapot. For a
bit more on acid and scale build-up, see the
L.I. entry.
- HARM
- High-speed Anti-Radiation Missile. Often called HARM missiles for short.
- Harmetz
- Aljean Harmetz is an engaging and thorough historian of moviemaking. She
wrote The Making of The Wizard of Oz and many other film-related
books. She gets an entry here because one of her books is a source for
information on Casablanca that's scattered
around the glossary. The book was originally published as Round Up the
Usual Suspects: The Making of Casablanca--Bogart, Bergman, and World War II (NY: Hyperion, 1992). Subsequent
editions (1997, 2002) were published by Hyperion using the original subtitle as
title (The Making ...). Where explicit reference is made to the book, I
have checked the updated edition published for the sixtieth anniversary of the
1942 movie.
- Harol
- How the English name Harold ends up being
rendered (and written) in Spanish. One word
that's a real pain to translate from English to Spanish is manifold, in
any of its scientific or technological senses. I've suggested manifol.
The Spanish congener of English standard is estándar.
- haroset, haroseth
- A sweet sort of chunky paste made of broken and crushed nuts and a bit of
fruit pieces and kosher-l'pesach wine. It's part of the traditional Jewish
Passover meal, the constant components of which all have explicit and standard
symbolic values -- ``signifieds'' to use the pomo
term filched from Ferdinand de Saussure. The signified of haroset is mortar.
(The Hebrew slaves in Egypt were supposedly forced
to use mortar without straw.
This bit is probably true, but it was not a special hardship; Egyptian mortar
never contained straw.) I believe it tastes sweeter than mortar, though not
having tasted moist mortar, I'm not sure (see, however, the granola entry). Matzah is not supposed to
symbolize drywall, but it's not supposed to taste especially good either. It's
the ``bread of affliction.'' Unleavened bread was part of the Spring harvest
festivals of many agrarian societies, way back when.
The Passover seder is somewhat technically demanding and confusing. A frequent
error is confusing haroset with hreyn (Russian name, adopted in Yiddish, for
horseradish, ``bitter herbs'').
Now I finally have the appropriate entry for Craig's ``symbolic disputation''
joke. Later.
- HARPS
- High Accuracy
Radial velocity for Planetary Searcher. There's no hyphen in ``High
Accuracy'' for the same reason that the object of ``for'' is unclear: HARPS
belongs to the European Southern Observatory (ESO)
and is therefore named in Broken English.
HARPS ``is dedicated to the discovery of extrasolar planets,'' and it has
discovered most of the smallest ones. It first went into operation in February
2003.
- Harris Semiconductor
- Once made a computer operating system called
``Vulcan''; yet still in business and even
on the net.
- HART
- Highway-Addressable Remote Transducer.
- Harvard architecture
- One of the non-von Neumann
architectures for general computing machines (computers), in which
instructions are just a kind of data. The term is conventionally used to
refer to any von Neumann-like architecture which differs from a pure von Neumann architecture primarily
in distinguishing instructions and data. In implementation, this means that
data and instructions are stored in different memory regions, and that either
separate buses or separate bits of a parallel bus are used to communicate
instructions and data. The extra communication bandwidth speeds computation
(duh).
Part of the reason for using Harvard architectures is to avoid the endless
loops, file corrupts and other dangers that occur when instructions can modify
themselves. There is a common notion that the von Neumann machine is somehow
more powerful or capable of more general tasks than a Harvard machine. This is
not true, since within any Harvard machine it is always possible to simulate a
von Neumann machine which uses only the data memory. (Of course, it is also
possible to simulate a Harvard architecture within a von Neumann machine.)
This entry is a mess because really, when one is talking Harvard or von Neumann
architectures, one is usually discussing abstract machines, Kolmogorov entropy,
and all that effete stuff about computability. So really the comments about
implementation are otiose. I ought to go back and fix the entry, but I'm lazy.
When (and where) I was in grad school, people going for a Ph.D. in the Computer
Science Department were really just doing an oddball sort of abstract
mathematics. The joke went that the first time they ever used a computer was
to word-process their dissertations. (This was before email.)
- Harvard of the South
- A popular epithet. It is possible to identify four distinct tiers of
Harvards of the South.
In the top tier are old private liberal arts colleges that
- are known nationally although
- they do not have an NCAA
division I football team, and
- are known to be ``known as `the Harvard of the South' '' by
at least one dozen (12) people outside the South who are not either
alumni of that school or their close relatives. (These people believe
that this is the only school bearing that epithet.)
Strictly speaking, the first tier comprises only Duke and Vanderbilt, but
considering that (a) they don't even have a decent basketball team and (b) my
pal Marvin went there, I also include Rice University in the first
tier. I further include the University of Virginia, so that if anybody tries
to thin the ranks of the first tier, there will be another school that
goes before Rice. To be fair, because of Rice's location (Houston) it is
less well-known than Vandy (in Nashville, Tennessee) or UVA. If one were to judge by how freely and
unapologetically the alumni use the epithet, then Rice would rival Duke.
(Nashville, incidentally, is known by its inhabitants as ``the Athens of the
South.'' This is discussed at the Athens entry, naturally.)
The University of Virginia, the only public university in the top HotS tier,
was Thomas Jefferson's last hurrah. Joseph C. Cabell (1778-1856) was
Jefferson's principal strategist and assistant in founding the university. In
a
letter of January 22, 1820, to J.C. Cabell, Jefferson worried that
Virginians educated at Harvard would turn into ``fanatics & tories.''
In the second tier are schools with only a regional HotS reputation: Emory
(discussed at the S.P.D. entry) heads this
list, followed by Tulane and Ole Miss
(University of Mississippi).
Schools of the third tier have a qualified HotS reputation. These are schools
about which it is said that ``it is said that some people call it the
`Harvard of the South'.'' The epithet is usually deployed ironically or in a
way that can be defended as facetious if challenged. This group is rather
ill-defined; since virtually no one is willing to claim baldly that one of
these schools is the HotS, the entire charade is based on rumors of
mis-overheard jokes. Most of these schools have to be identified as Foo
College in Bar City, State_Name_Here. Many of the third-tiers are members of
the Associated Colleges of the South (ACS),
particularly Centre, Millsap, Morehouse, and Sewanee (``University of the
South''), and many of the remaining ACS schools qualify marginally (Davidson,
Furman, Hendrix, Rollins, Trinity (TX)). Non-ACS third-tier HotS schools are
Fisk, Hampton University (Hampton, Va.),
Livingstone College of Salisbury, N.
Car. (main claim to fame: ``W.E.B. DuBois once referred to Livingstone as the
`Harvard of the South' ''), Wofford
College (in Spartanburg, South
Carolina) and SMU. (Also one McNeese State
University -- sports reporting, you know.)
The fourth and lowest tier of schools have bureaucratically mandated HotS
``reputations.'' For example, according
to this linked news item, ``UF [University of Florida, Gainesville]
administrators have designated the school the `Harvard of the South'.''
I must have missed the announcement. UT Austin has also been called a HotS.
Whether this was pursuant to an administrative order I do not know, but (a) I
do know that they have tried to buy a reputation by recruiting top scholars
(nothing wrong with that) and (b) I have been in Austin, and it does not feel
even remotely like Cambridge.
To summarize: one way or another there are two dozen Harvards of the South
distributed among the states that seceded to form the Confederacy. Of those eleven states, only Alabama
does not claim to have a single HotS. If you enjoy devil-may-care honesty (and
I sincerely hope you do) then you'll want to read this 1996
interview of Auburn University history
professor J. Wayne Flynt. My man
Flynt! He delivers a coruscating jeremiad that includes this:
I think the popular culture in Alabama has a perception of a limited future.
In fact, recent polls indicate when Alabamians were asked "what do you
envision for your children?" in terms of their future occupations, the
single largest category of response was to be in fast food. The level of local
support for education is so poor that (the population perceives) there is no
future in this community; there is going to be a steady collapse of community
to the point where it may be too late. This brings the question can it be
collectively too late for a state, and I think the answer is yes.
Then the interviewer had the gonads to ask (reading from a list, I suppose),
``Who is responsible for the success of education in Alabama?'' His answer
appears to be cut off, but it begins ``That's sort of like asking who's to
blame for the problems.'' I think Neil Young was on to something.
Also deserving of mention: Baylor (at Waco, Texas),
the ``Harvard of Southern Baptists.'' The riffs on this idea are endless.
Your next stop on the tour of these riffs is the S.P.D. entry.

- HAT
- Histone AcetylTransferase. HAT enzymes activate genes in the nuclei of
cells by transferring acetyl ``tails'' onto histones. Histones are small proteins around which DNA coils to form structures called nucleosomes.
Compact strings of nucleosomes form chromosomes. An added acetyl-group tail
loosens the DNA coil, enabling its genes to be expressed. Histone deacetylases
remove the acetyl group, reversing the process.
Regarding chromosomes: ordinary human cells have 23 pairs of them. Human germ
cells, as they used to be called, or gametic cells (sperm and egg cells), are
haploid: they have half the usual complement of chromosomes. Cells undergoing
mitosis have double the usual complement just before fission, and red blood
cells have
no nuclei. (Although paired chromosomes are pretty common in the somatic cells
of eukaryotes, there are various organisms which exhibit haploidiploidy: males
develop from unfertilized eggs and have haploid somatic cells. You think
that's weird, just be glad I don't define haploidization. Haploidiploidy
happens with honeybees, but not with chickens. So the egg you had for
breakfast was never going to hatch into a bird, since it wasn't fertilized.)
There are a number of genetic abnormalities in humans that involve unusual
numbers of chromosomes (``aneuploidy''), and a few of these are not immediately
fatal. The best known is Down syndrome (an extra copy, ``trisomy,'' of
chromosome 21), which modern treatment has made quite survivable. (Strictly
speaking, this only accounts for about 95% of Down cases. In the translocation
type of Down syndrome, extra chromosome-21 genes are inherited via DNA that has
translocated onto another chromosome.)
A number of aneuploidies involve the sex chromosomes. This page lists a bunch.
Read it here now. Eventually I'll scatter this stuff to more appropriate

The Mickey Mouse ears atop the "Earffel Tower" (a water tower in the
Disney-MGM Studios addition to Walt Disney World, created by Caldwell
Tanks, Inc.) correspond to a hat size of 342 3/8!
``Hat size'' is also a ready euphemism for intelligence. (E.g., ``they
don't publish chemistry textbooks in your hat size.'')
- Haupt
- What is your problem? Do you need a separate entry for every slightly
different word?! Don't waste my time! Everything you need to know is at the
Hauptwort entry.
- Hauptwort
- German, `noun' (i.e., noun substantive).
The headword of this entry is a compound noun that can be analyzed as `head
word.' Haupt is a cognate of the English word head, and alone
that is what it means. It is approximately synonymous with
Kopf. In compounds, however,
Haupt is widely used in figurative senses like `main, principal,
leading, chief.' Kopf can also be used figuratively or at least
metonymically, but its compounds are less abstract. E.g.:
Kopfarbeit is `brain work,' Phillips-Kopf is `Phillips head.'
Der Kopfbahnhof is `the rail head; der Hauptbahnhof is `the
principal train station.'
Amsterdam Hauptbahnhof is `Amsterdam Central' (Amsterdam Centraal
in Dutch). In June 2005 I was able to google a grand total of three instances
of Penn Hauptbahnhof, all serving as translations to German of `Penn
Central Station.' Journalists, sensibly, generally avoid attempting a direct
translation. Penn Central Station was the name given in various cities to the
train station where the old Penn Central Railroad stopped.
The headword of an entry, in general, is das Stichwort. Der
Stich is a cognate of `the stitch,' but is used for a wide variety of
related penetrations -- `stab, dig, sting, pinprick.' You can think of
Stichwort as `incised word.' German also has die Rubrik, and
`unter der Rubrik ...' does still mean `under the rubric [of] ...,' but the
word's meaning has drifted more decisively in German than in English, and now
Rubrik itself primarily means `category' (figurative sense of
rubric) and `[newspaper] column.' You could use s.v.
A headword, in the technical linguistic sense of a word that may be
modified by an adjunct, is simply called a Nukleus in German.

- have got to
- A compound modal (that takes an infinitive predicate) meaning about the
same as must or have to. Like must, it isn't very
conjugable. If you have got to do something today, then tomorrow you would
probably say that you ``had to do it'' (rather than ``had got to do it'').
One may think of the word got as an intensifier for the compound modal
have to. In fact, one usually encounters the contracted forms (I've
got to rather than I have got to), and these seem to have about the
same force as the no-got forms.
There was a popular BBC program (or programme,
anyway) on the English language, and I think it was in a companion paperback
called The Story of the English Language or something that I read the
claim that the use of ``have got to'' began in Britain and was brought back to
the US by American soldiers after one or another World War. This turns out to
be at least partly incorrect.
The hypothesis of a British origin has the following plausibility: one might
expect a verb following have in a compound construction to be in the
past participle form. The past participle form gotten is preserved in
American English, while got is used (as both past and past participle)
in British English. Hence, ``have got'' in the sense of ``have received'' is
common in Britain and rare in the US. Then again, ``I've got'' in the loose
but common sense of ``have'' is common in the US, so this isn't very
strong evidence.
In fact, however, the have-got-to idiom was in common use in the US at least as
early as shortly after the Civil War, while it was apparently not in common use
in Britain as late as 1909. My evidence for both claims (weak for the second)
is in Sir William Butler: An Autobiography, which Lieut.-General the Rt.
Hon. Sir W. F. Butler, G.C.B. wrote in the year before he died on June 7,
1910. The times he spent in North America included a period in 1866 when he
joined the buffalo hunt in the Nebraska Territory. He describes this toward
the end of chapter 6, and digresses thus:
What impressed me most strangely about the men I now came in
contact with was the uniformity of the type which America was
producing--northern, southern, eastern, western, miner, hotel-keeper,
steamboat-man, railroad-man, soldier, officer, general,--the mould was the
same. `There has got to be' seemed to be the favourite formula of speech among
them all, whether it was the setting up of a saloon, the bridging of a river,
or the creation of a new State. `There has got to be' this railway, this
drinking bar, this city, this State of the Union. Nobody dreamt, except when
he slept; everybody acted while he was awake. They drank a good deal, but you
seldom saw a man drunk, and you never saw anybody dead drunk. They sometimes
shot each other, they never abused each other; they were generous,
open-hearted, full of a dry humour, as manly as men could be; rough, but not
rude; civil, but never servile; proud of their country and boastful of it and
of themselves. That day and evening, and all the other days and evenings I
spent at Fort Kearney, were the same--good fellowship, good stories round the
festive board at night, hard riding and hunting all day over the glorious
prairies.
It's probably worth noting that there is a certain celebratory tone in much of
Butler's writing (particularly in his biography of General Napier), but he is
not uniformly laudatory. The business about story-telling reminds me of some
observations Gertrude Stein had in
Wars I Have Seen (pp. 248-9). This is also an
autobiography, like pretty much all of her
books, and it was written after the liberation of France, and so also in the
year or two before she died.
Gradually as the joy and excitement of really having Americans here really
have them here began to settle a little I began to realise that Americans
converse much more than they did, American men in those other days, the
days before these days did not converse. How well I remember in the last
war seeing four or five of them at a table in a hotel and one man would
sort of drone along monologuing about what he had or had not done and the
others solemnly and quietly eating and drinking and never saying a word.
And seeing the soldiers stand at a corner or be seated somewhere and there
they were and minutes hours passed and they never said a word, and then one
would get up and leave and the others got up and left and that was that.
No this army was not like that, this
army conversed, it talked it listened, and each one of them had something
to say no this army was not like that army. People do not change, no they
don't, when I was in America after almost thirty years of absence they
asked me if I did not find Americans changed and I said no what could they
change to except to be Americans and anyway I could have gone to school with
any of them they were just like the ones I went to school with and now they
are still Americans but they can converse and they are interesting when
they talk. The older Americans always told stories that was about all
there was to their talking but these don't tell stories they converse and
what they say is interesting and what they hear interests them and that
does make them different not really different God bless them but just the
same they are not quite the same.
For more on Stein on Americans telling stories in France, and an indication of
how all her books are autobiographies, sometimes in two different senses, see
the S.O.S. entry. The issue of American cultural
homogeneity is touched upon at the 5-2
defense entry, in a quote from Everybody's Autobiography (by and
about Gertie, of course).
William Butler's use of the word mold is reminiscent of ``the melting-pot''
metaphor of America, popularized by Israel Zangwill's play of that name. (In
Act I: ``A fig for your feuds and vendettas! Germans and Frenchmen, Irishmen
and Englishmen, Jews and Russians--into the Crucible with you all! God is
making the American.'') Zangwill's play was the hit of 1908, the year before
Butler wrote. (The metaphor was used by others, such as Ralph Waldo Emerson, in earlier but much less
well-known instances.)

- HB
- Postal code for Bremen, one of the sixteen states (Länder) of
the German Federal Republic (FRG). [Like most of
the country information in this
glossary, Germany's is at the domain code .de.]
The state of Bremen comprises two urban areas -- Bremen and its seaport city
Bremerhaven. (The aitch might refer to Haven, `port' or to Bremen's
history as a Hanseatic city; I don't know. The German word for port is
Hafen, which would be pronounced the same if it were spelled
Haven, and which is of course a cognate of the English word
haven. Bremerhaven was founded very recently by European standards --
1827, but spelling evolves.)
Bremerhaven is on the North Sea coast, Bremen is thirty-plus kilometers up
the Weser River. All the land borders of the two cities are with the
surrounding state of Lower Saxony (NI).
All together Bremen is the smallest
Land, both in terms of area (404 sq. km.) and population (660,000 in

- HalfBack. An offensive position in American football.

- HB
- Hard Black. A pencil lead of medium hardness. Softer leads run
B, 2B, 3B, etc. (up to about 9B); harder ones are F (presumably Firm),
then H, 2H, 3H, etc. (up to about 10H). Other grading systems have also
been used. See The Pencil by Henry Petroski.
In the same book he also explains that when pencils as we know them were first
invented, they used unprocessed, natural graphite -- and the only known source
of this with decent quality was a single mine at Borrowdale, near Keswick,
England. This monopoly lasted for over 100 years.

- hbar in HTML
- It has been a vexation that hbar, probably the most frequently-occurring
special symbol in quantum mechanics, has been unavailable in any fonts that
one could expect visitors to one's website to have. The symbol finally has a
home in Unicode, at U+210F, but most fonts still
don't contain a glyph for it. (It does occur in the Apple Symbols font and in
various Hiragino fonts for Japanese.)
I recommend using an alphabetic character from Maltese (U+0127; the letter name
is ħe). Barring that, if you'll pardon the expression, there are other
alphabetic characters. The version of Cyrillic alphabet used in Serbian has a
small letter tshe (U+045B) that is similar. Both of these symbols have the
form of a lower-case Roman letter aitch with
horizontal bar through the upper half of the letter, and both are widely
available in italic variants. When italicized, both would pass for ordinary
hbar glyphs but for the fact that bar in hbar is a slanted stroke (upper right
to lower left). Another option is Ogham letter ruis. This is less similar and
less common, which is just as well: it's supposed to be at U+168F, and
apparently is there on Mac fonts, but the Microsoft fonts I've checked have a
grave-accented W there. Another approach is to use strike-through, but that
generally puts a horizontal bar below the middle of the character line, so it
looks pretty bad. Here are the approaches described:
- ℏ: ℏ
- <i>ħ</i>: ħ
- <i>ћ</i>: ћ
- <i>ᚏ</i>: ᚏ
- <i><del>h</del></i>:
h
(I use <del> because <strike> and <s> are deprecated.)
Another approach is to create the page in LaTeX (where one has \hbar) and use one of the standard
conversions that generates gifs for all the
formulae.
- HbA2
- A normal minor (1.5% to 3.5%) component of total hemoglobin (Hb). Levels of HbA2 are elevated in various diseases.
- HbC
- An abnormal component of hemoglobin (Hb), common in
peoples of West Africa. In a certain kind of situation this leads to
sickle-cell trait and sickle-cell anemia. The trait seems to have survived
because HbC also generally confers some protection against at least one
tropical disease.

associated with lengthy estate closing delays, which sometimes can drag on for
years''?

- HBCU
- Historically Black
College or University. (The plural -- HBCU's or HBCUs -- should be
expanded ``... Colleges and Universities.'') HBCU's are schools whose
earliest instructional buildings were constructed of basaltic rock or black
marble, obsidian in a pinch. Pitch is preferred as a roofing material, but I'm

- A provider of health, property, and other
insurance plans now formally known as HBF Health Funds, Inc., and known
from October 1945 as The Hospital Benefit Fund of Western Australia. Western Australia, you will recall, is not just a part of
Australia but a state, with its capital in Perth, which might be considered a
metropolis more or less by default. The
Metropolitan Hospitals Benefit Fund (MHBF) was established there on April
Fools' Day in 1941. In 1944, members' coverage was extended to all hospitals
in WA, which represented an enormous expansion, at least geographically. The
em was dropped in recognition of that fact from October 5, 1945.
- HbF

In 1992, the Greenville (S. Car.) Department of Social Services sent a
termination notice to a former beneficiary. This stated in part:
Your food stamps will be stopped effective March, 1992, because we
received notice that you passed away. May God bless you. You may reapply
if there is a change in your circumstances.
Reportedly, the ``May God bless you'' was inserted at the keyboard by a
sympathetic civil servant. I don't believe this answers all reasonable
questions that might occur, however.
Under proposed welfare reforms now being considered in the House of
Representatives under the Republican regime, the letter would have read
``Your food stamps have been stopped effective March, 1991, because we
figure you'll be dead soon anyway. May the Market have mercy on your
estate. If there is a change in your circumstances, we'll call you.''
Under terms of the 1988 Democratic Party platform (by all accounts, year of
the last admittedly liberal US presidential campaign), the letter would have
read
``Your food stamp allocation will be increased effective March, 1993,
because you haven't been eating well. May a superior rational being,
if you choose to acknowledge one, empower you emotionally. If you have
any material desires, please allow us to fulfil them.''

The strongest acid that any ancient civilization knew about was acetic acid -- the chemical which, as its name
suggests, makes vinegar sour. (Follow the link for etymological details.)
Acetic acid is not a strong acid. Over the course of centuries, mineral acids
were eventually made and discovered. In 1824, the English physician William
Prout demonstrated that the gastric juices of animals contain hydrochloric
acid. (So much effort, and all that time the alchemists were carrying around
little sacs of acid at the ends of their esophagi.) Prout's contemporaries
were incredulous.
Hydrochloric acid was at the center of some confusion at the beginning of the
nineteenth century. For details, see the remarks under

gets killed so early that it's a non-speaking part. In blood
cholesterol (really
lipoprotein), you start out with one
``good'' which (HDL) and one or two bad whiches (LDL, or LDL and VLDL), and
you can count your blood happy if there's only four times as much of the
latter as of the former. There's also
triglycerides, the winged monkeys of blood chemistry. All of this
goes to show that, while in fantasy the odds are two to one in your
favor, and you can expect help from farm workers, unemployed metal workers,
and wild cats, in reality the odds are maybe 4:1 against you, and your
doctor wants insurance identification (ID) in
advance.

- HDT
- Heat Deflection Temperature. One measure of the softening characteristics
of polymers, described in ASTM test method D468-72.
A plastic (i.e. polymer) bar of rectangular cross section is loaded as a
simply supported beam. The load on the bar is adjusted to produce a maximum
fiber stress of either 1.82 MPa (264 psi) or 0.455 MPa (66 psi). The center
deflection of the bar is monitored as the ambient temperature is increased at a
uniform rate of 2°C/min. The temperature at which the bar deflects
0.25 mm (0.01 in.) from its initial room-temperature deflection is
called the heat deflection temperature at the specific fiber stress.
In order to allow rapid characterization (temperature increase between 1.8 and
2.2 °C per min.), the fiber is immersed in an inert liquid medium such as
mineral oil. The buoyancy of the
fiber in liquid is a negligible effect.

The technical problems in transmission and display are formidable, but some
Japanese receivers, and some program transmission, were already in operation in
Japan in 1990. At about that time in the US, the FCC put out a call for participation, to define the
encoding and transmission schemes that it would make standard for the US. In
the competition (to see whose idea the FCC would essentially adopt whole as the
standard--as happened with NTSC), it became clear
that the way to go was to have digital signal encoding, with substantial
compression of the transmitted signal, often with only an image-modification
signal sent. SECAM (the French color TV system)
has been using storage of a full screen of data for years on traditional
resolution, so by now the approach of storing and updating is not a significant
technical hurdle (vide VRAM).

because it was not known to be a noble gas when it was discovered and named.
The isotopes with one and two neutrons were once called He I and He II,
respectively. They have rather different low temperature properties,
essentially because He I is a composite fermion
and He II is a composite boson.

The proceedings of the International Conference on the Science of
Superconductivity, Hamilton, New York (1963), were
published in Rev. Mod. Phys. vol. 36 (1964). One of the
interesting articles there is K. Mendelssohn's ``Prewar Work on
Superconductivity as Seen from Oxford,'' (pp. 7-12). He writes:
... Nowadays, it is not generally appreciated that one of the main reasons for
making ... miniature liquifiers was the scarcity of helium gas, which had to be
extracted laboriously from Monazite sand. The arrival of the first American
helium from gas wells was an important event, and I went down to the Berlin Customs House to open the crate. But then the
official wanted to open the cylinder too, to see whether it contained liquor.
He only relented when I assured him that I should be most disappointed if it
did.
As I was leaving the library after reading Keesom's paper [W. H. Keesom and
J. N. van den Ende, Comm. Phys. Lab. Univ.
Leiden, no. 219b (1932)], I had to duck a few bullets which were flying
through the streets of Breslau, heralding the
approach of Nazi rule, and it became
clear that the cooling experiment would have to be deferred a little.
... I say `nearly all' laboratories, because the Russian colleagues who had
signified their intention to attend failed to turn up. We were given the glib
explanation that they were too busy to attend meetings. I was particularly
disappointed because Shubnikov's group in Kharkov was carrying out work
[L. V. Shubnikov, V. I. Khotkerich,
J. D. Shepelev, and J. N. Rjabinin,
Physik. ZS. Sowjet
Union, Suppl., p. 39 (1936)] very similar to ours, but communications
had been limited to exchanges of reprints with greetings scribbled on them. As
it happened, Shubnikov was arrested shortly afterwards on charges from which he
was to be posthumously exonerated twenty years later.

- Postal code for Hessen, one of the sixteen states
(Länder) of the German Federal Republic (FRG). [Like most of the country information in this
glossary, Germany's is at the domain code .de.]
The state's area is 21,114 sq. km.
Its population was 5,508,000 by the census of 1987, estimated at 6,031,000 for
1997. Hessen was part of the old West Germany; its capital city is Wiesbaden.
Before the Federal Republic, Darmstadt was the capital of the state.
IIRC, the Electrical Engineering and Physics
Departments at UB have student exchange programs,
each with a University in one of these two Hessian cities.
Hessen is one of those German proper nouns that used to have a slightly
different form in English (Hesse), but whose German name is slowly being
accepted as the standard English name. The best example of the phenomenon
is the German name Frankfurt, which has almost completely displaced the
older English equivalent Frankfort,
q.v. As it happens, Frankfurt am Main is in Hessen State, 17 miles
north of the smaller city of Darmstadt.
Hesse, of course furnished the largest group of mercenaries for the British
effort against its rebellious North American colonies late in the eighteenth
century, and German mercenaries generally came to be known as Hessians. A
fly whose appearance was first noted at the time of the Revolutionary War
came to be known as the Hessian fly in the US, and the American fly in Hesse.
During the Revolutionary War, Continental and state militia forces combined
totalled about 20,000 troops, while British forces numbered about 42,000
regulars plus about 30,000 German mercenaries. US forces lost most of the
major battles they fought, controlled none of the major cities, suffered
disunity, mutinies, treasons, incompetent generals, bad cash flow and military
supply problems and worthless government scrip. The British had some problems
too, and they lost the war. What's this information doing here in the Hesse
entry? Oh well.

His reaction on sampling a particularly distasteful dish is to remark
that it would have sold well in his health food store. (He is also offered
unfiltered cigarettes as an effective tranquilizer by his physician hosts,
who lament that in his day the healthful properties of double fudge and

- hearing
- I read once that in ordinary conversation it's usually necessary to guess
something like 30% of the sounds (more as you age). This morning, December 14,
2003, after spending a few hours offering my five-dollar bill to a refractory
bill changer, I relented and put the five in the soda machine. In an
experiment earlier this year, I had discovered to my horror that the soda
machine returns dollar coins, so naturally I never put in more than a dollar
over the price. But this day I was pleasantly surprised. Walking back into
the library, I shouted at the guards:
Hey! Great news! The soda machine doesn't give those stupid dollar coins any
more!
The older guy replied:
Yeah, they confirmed it!
He referred, of course, to the reported capture of former Iraqi dictator Sodam
Achine.
My accent is also mentioned at the adult education entry. There's another
entry that describes a pattern-recognition failure using the sense of sight,

- heavy holes
- Compound semiconductor people throw around terms like this all the time
without giving it a second thought.
- heavy metal
- In the human health context, heavy metals are transition metal elements
in the sixth and heavier periods, which should be present only in small
quantities. Like lead (Pb) and mercury
(Hg), for instance.
In microelectronics, heavy metals are period-four and -six transition metals
that are troublesome contaminants because of their electrical properties.
Au (see Gold) and Pt are lifetime killers in Si.
Fe, Cu, Ni, and Cr, in period IV, have atomic weights in the range 51 to
63, or about twice that of Si. They're at the top of the famous curve of
(nuclear) binding energy, so they're rather common.
Because the conventional definitions of heavy metals include only transition
metals, they exclude, amusingly, barium (Ba), whose
name means heavy.
Heavy metal is a broad category of rock music characterized by electric-guitar
amplifier distortion in the lots-to-huge range. Lyrics are often deemphasized
but never absent. If they took out the lyrics, it would be a new kind of music
that might be called Doo-Wop Scream. Some scattered other thoughts on heavy
metal at the E.T.I. entry.
It was for an election of student representatives in junior high school that I first used one of those those
walk-in gray, steel-construction voting booths. You know which ones I mean --
those curtained half-booths with flip levers that click clearly and a big
red-handled lever that gives a solid ka-chunk as it registers your vote and
pulls the curtain. If you're not strong enough to pull the lever, you've got
no business voting. I loved those things. The popular model came out in 1960,
based on a design originally by Thomas Edison. I've used a half a dozen
different kinds of voting machine in the years since, and it's never felt as
good. No wonder voter turn-out has declined: there's nothing to look forward
to any more. Bring back the heavy-metal voting machines!
- heavy water
- Water in which the hydrogen atoms are of the deuterium isotope:

If you like to think in exotic terms, and when you consider that water is

to an O= ion.

``fatta la legge, trovato l'inganno.''
- HECS
- Higher Education Contribution Scheme.
The system by which students pay for attending public tertiary education in
Australia. An ICR loan scheme.
(See the ``Going to Uni website'' if
the link above is gone.) It sounds a rather inauspicious name.
HECS was introduced in 1989. Until then, Australian students paid no tuition
fees. John Dawkins, Minister of Education in the Labour government at the
time, argued that this constituted an unfair subsidy to the better-off families
that sent students to college. Under HECS, each student is assessed a tuition
obligation (initially it was AUD 1800 per year of study), and they have
the choice of paying immediately or deferring payment. If payment was
deferred, no interest is ever charged, although the obligation is indexed to
consumer prices. (Actually, there is an effective charge for accepting the
loan, because students who pay immediately receive a discount, but most
students choose to defer.)
Repayment of the loan is keyed to income, and in fact functions as a kind of
income-tax surcharge. Starting after the end of their period of studies,
students are required to repay in amounts (called ``deferred contributions''
to the higher education system) that depended on how much their income exceeds
a threshold of the average industrial wage (about AUD 30,000 in 1989).
Contributions would be collected until the loan was repaid or 25 years had
passed, whichever came sooner.

- Heidelberg United Soccer Club
- An Australian club
founded by immigrants from northern Greece in 1958. Actually, the team has
been through a few names in its history, and the current official name is the
Heidelberg United Warriors. It's also known as ``the Bergers,'' and many of
its fans still call it by its original name Megas Alexandros (or
`Alexander the Great'). Oh how the mighty are fallen. Alexander was one of
the founding members of Australia's National
Soccer League in the 1980's, but it ended its 1994-5 season with the worst
record in the NSL. In the off-season, claiming they were losing a million
dollars a year, NSL cut Heidelberg, the Zebras (another Melbourne club with a
losing record), and most controversially the Parramatta Eagles. They added
Newcastle and the Canberra Cosmos, for a net decrease from 13 teams to 12.
Now, to tell you the truth, I don't give a rat's ass about Australian Soccer.
Nothing personal: it's just that I'm an American, and Americans don't care
about soccer.
It's not unconstitutional for an American to care about soccer -- it's not even
illegal in most states. It is merely impossible. I'm not sure whether it's a
logical impossibility or a biological one, but it can't happen. (I did find
the NSL administrative shenanigans exciting, though.) Yet you know that I
wouldn't drag you this far through a glossary entry just because a Macedonian
Greek soccer club in Australia is called Heidelberg United. (Alexander was in
Fitzroy before it moved to Heidelberg.) That's why you're still reading.
(Hello?!) There's got to be more entertainment value in it than that, and
there is. So keep the faith, and read on.
Since it was dumped by the NSL, Heidelberg has played in the Victorian Soccer
Federation. It won the Victorian Premier League championship in 2001, but the
next year it fell to last place in the VPL and was booted down to the State
League's first division. I don't know what that is, but in everything I've
read so far (including the team's own sugarcoated
history), the sentence that mentions State League 1 always contains the
word ``relegated.'' Anyway, under current (2004) president Elias
Deliyannis, the team has signed a number of former NSL players. It's pushing
to win the State 1 championship in 2004 and bid for promotion back to the VPL
for 2004/2005. (We actually have another VPL
entry.) But it's been hard to find sponsorship. Deliyannis heard that Gotham
City, a local business, had backed motor racing and netball in the past.
(They've also supported kickboxing.) He approached the owner, who committed to
a ``corporate sponsorship package'' of about $20,000. Gotham City is a South
Melbourne ``institution'' (that euphemism comes up a lot) which promotes itself
as Australia's only ``six-star brothel.'' This institution charges ``$240 an
hour and an additional $30 for fantasies.'' (All amounts in Australian
dollars.) Reporter Peter Desira broke the story.
Now you shouldn't worry that young children will be exposed to anything their
parents wouldn't want them to see. ``There definitely won't be signs at the ground or on our shirts,'' according to Deliyannis.
He understands that ``this has to be dealt with in a sensitive way.'' So
what's in it for Gotham? Well, ``the owner believes he will get value by
word of mouth...'' (my italics). Is that what Delyannis meant by saying
that they were ``endeavouring to expose their business in a tasteful way''?
This ``sensitive'' business can get pretty sticky. Wording is subject to
alternative interpretations. ``It's a straight-out cash deal. There are no
additional services offered, or asked for.'' Mm-hmm. The team website expresses great
pleasure at all the attention. In an emailed announcement of the deal, the
team urged fans to ``support the girls who support us.'' Athletic supporters,
sure.
I really want to write about the NSL corporate gamesmanship that happened in
1995, but I haven't sorted it out yet. So instead, I'll explain that Elias is
one of those names with a different form in the vocative. So if you're talking
about Elias, that's what you call him, but if you're talking to
him, it's Elia. Also, Delyannis looks like a Cypriot name (because of
the -is) rather than a mainland name, but you never know.
- heir-head
- Paris Hilton, Nicole Richie, etc. To be fair to Paris, while she may trade

As long ago as 1997, a children's book was published with the title Duh -
Heir Head: And Other Stories That Are Even Dumber than Dumb and Dumber, by
Allen B. Ury.
According to the publisher, it's ``packed with the air-headed action of a
brainless gang of geeks, all the stories in this dud-namic new series serve up
stupid in a very smart way. Characters bungle their way from story to story in
this stupendous series, creating havoc and fun for midgrade readers--even the
quick-witted ones.'' No, I don't understand where the pun comes in.

- HEL
- Header Extension Length. Not mentioned in my spam lately.
- helar
- Spanish verb with the basic sense of `to
freeze,' derived from the Latin gelare. It
has a range of senses that substantially overlaps that of the more common
Spanish verb congelar. I have a sense that in intransitive uses (when
the verb's subject itself freezes) helar is more likely to be used
without a reflexive suffix or pronoun than congelar would be. In other
words, helar is more readily regarded as an intransitive verb. But this
is a quantitative issue, probably subject to regional variations.
In metaphorical senses related to money (price freezes, freezing of assets,
etc.), the usual verb is congelar.
Before the discussion to follow it should be stressed that when helar
and its inflected forms are used nonmetaphorically as verbs, some
solidification is usually implied. Thus, for example, ``esta noche
helará,'' `tonight there will be frost' (not just cold). When fruit
or plants are said to helar they have not just been chilled but gone
hard. The only standard exception I can think of is in describing a person as
freezing (i.e., suffering extreme cold), which may be considered either
dramatic hyperbole or else a way to avoid some of the transferred senses of
enfriar (`to cool, to make cold'). (Here one really must use the
reflexive enfriarse, `to become cool, to get cold.' You probably also
want to know that resfriarse is `to catch cold.')
The word for ice, hielo, is more evidently and straightforwardly related
to helar than to congelar. (Helar is a stem-changing verb
-- see hielo for details -- so the
e/ie distinction is ignorable.) Perhaps that is why English terms related to
ice (rather than freeze) seem preferentially to correspond to
helar words. For example, helado, literally `iced,' means `ice
cream.' (This is closer than it looks now; the original English term was
iced cream.) Likewise, heladera
is `refrigerator,' the technological descendant of an ``ice box.'' A
congelador is a `freezer.' And heladera also means `ice cream
woman.' (One who sells or makes it, not is it.)
A different word altogether, and not very common now, is helear, `to
make bitter.' It's from hiel (`bile'),

- Helen of Troy
- Parent company of Revlon and Vidal Sassoon. According to most reports,
the original Helen had an illicit relationship with Paris. It was more than
a brief fling. Paris, the capital of France (in Europe, a
``continent'') is historically associated with women's fashion. The poet
Siegfried Sassoon made many classical allusions in his work. More about Ziggy

- Hellenistic
- Pertaining to the period, or approximately to the period, from the death of
Alexander the Great (323 BCE) to the end of the Ptolemaic dynasty.
Peter M. Green's widely praised book about the Hellenistic era is entitled
From Alexander to Actium. Actium, now called Akri, is a promontory on
the coast of western Greece. A
naval battle took place there on September 2, 31 BCE, in
which the fleet of Octavius Caesar, commanded by Marcus Agrippa, defeated the
combined fleets of Mark Antony (Marcus Antonius) and Cleopatra (Kleopatra VII).
The lovebirds flew to Egypt. The next year Octavius pursued them there, and
the city of Alexandria surrendered without a fight. Mark Antony and Cleopatra
committed suicide. Cleopatra's death marked the end of her (Ptolemaic)
dynasty, and Rome annexed Egypt. (Although that was the end of the Ptolemaic
dynasty, it wasn't the end of people named Ptolemaeus. The most famous such
was the Alexandrian astronomer and cartographer Ptolemy, who flourished in the
second century CE.)
The ``Hellenistic Age,'' by that or a similar name, is one of the more useful
periodizations. After Alexander died, his
generals competed for the pieces of the empire he had carved out of the western
Asia and Egypt, and politically the region settled into a pattern that
persisted until Rome's expansion overran it. Culturally, the period was marked
by a diffusion of the Greek language, and Greek (Hellenic, as
distinguished from Hellenistic) ideas and culture.
Aristotle died in 322 BCE, so the Hellenistic era begins with the end of the
golden age of Greek philosophers. Although the Greek city-states declined
precipitously in political importance, however, Athens maintained its
preeminence as a center for philosophy.

to put in this entry anyway as a sort of gentle suggestion. What happened was,
I saw an announcement for the South Central Seminar
in the History of Early Modern Philosophy and I was moved by the music of
the two-word modifiers -- South Central Seminar, Early Modern

- hepatitis
- Literally, inflammation or disease of the liver. Hepatitis is also thought
of as a blood disease because of the liver's function in filtering the blood --
so signs of infection are most readily discerned in the blood. If it were
strictly a blood disorder, however, it could be called a hematitis or anemia.
[Cirrhosis is not a specific disease but symptom: liver fibrosis (replacement
of healthy tissue by fibrous tissue with nonfunctional cells), which may result
from any of many conditions, particularly malnutrition and hepatitis infection,
although one tends to think of alcoholism first. Hepatocellular carcinoma is
also associated with chronic hepatitis infections.]
More useful information can be found at the Hepatitis Information Network.
Although nonviral hepatitis occurs (bacterial hepatitis, hepatomas, and
food poisoning that may be referred to as nonviral hepatitis),
in current usage the unqualified term hepatitis usually refers to a viral
liver disease, of which six (A, B, C, D, E and G) are common. (The
corresponding viruses are typically called HAV, HBV, etc.; a namespace
collision looms -- cf. HIV.) Viral
diseases generally do not (except indirectly) respond to antibiotics.
- Hepatitis A, or infectious hepatitis, caused by an RNA virus.
Transmitted in food and water. A vaccine exists.
- Hepatitis B, or serum hepatitis. A DNA
virus primarily transmitted in blood transfusions, although
transmission via other bodily fluids occurs. Generally more acute than
A. A vaccine exists.
- Hepatitis C. Originally called non-A, non-B hepatitis, when
screening for A and B (starting in the 70's) in blood supplies failed
to eliminate all cases of hepatitis linked to blood transfusion.
There are many varieties of these RNA viruses, and some of the
variability in disease progression and responsiveness to treatment
(mostly alpha interferons, right now) seems to be associated with this.
The variability also makes the development of immunity or of a vaccine
more difficult (no vaccine exists at the time this entry is written).
A majority of patients with acute hepatitis C develop chronic HCV
infection.

It is estimated that as much as 2% of the US population is infected
with the virus -- of which number very few are aware of their

appropriately to liberal arts faculty or faculty at elite universities. The
group Rosenberg referred to was generally anti-socialist and pro-American and
knew it, in approximate contrast with the group it is now applied to. (Not to
make any broad generalizations or anything.) Someday we really ought to have
an entry for New York Intellectuals. Right now they only have another mention
at the WWIII entry.

- Hernandarias
- A contraction of the personal name of Hernando Arias de
Saavedra, and the name by which he is commonly known. The reference
information on him that I can find without going to the (nonreference) stacks
is sufficiently contradictory that I'm going to present it without prejudice:
According to R. Andrew Nickson's Historical Dictionary of Paraguay
(Metuchen, N.J. & London: Scarecrow Pr. Inc., 2/e 1993), his years were
1560 to 1643, and he was governor of Paraguay three times: 1592-1599,
1602-1609, and 1615-1621. He was the son of Governor Martín Suarez de
Toledo. [The current system of Spanish surnames did not become common until
the mid-1700's. Arias was probably named after his mother or less probably a
grandparent. The ``de Saavedra'' bit could be geographic or genealogical.]
According to Ione S. Wright and Lisa M. Nekhom's Historical Dictionary of
Argentina (Scarecrow, 1978), his years were 1561 to 1634, and he was born
in Asunción of Spanish parents. He was appointed lieutenant governor in
Asunción in 1592, and then served three times as governor of the
Río de la Plata area: 1597-1598, 1602-1609, 1614-1620.
According to the EUI, he was born in Asunción
and was the first creole to hold [high] public office in [Spanish] America. He
was governor of Argentina in 1591. The EUI doesn't give other dates, but says
he governed the extensive province of the Plata for many years. It also
explains that initially, his merits were not recognized by the Spanish court,
and this caused him to be passed over in favor of Diego Marín
Negrón (of whom I can find no other mention), but that Arias was allowed
to succeed him on his death.

- heroin
- This entry is not about heroin but about heroin (the word). And
it's not about the English word heroin, but about the Japanese borrowing
of that word, which happens to be written heroin in romaji.
English has a word heroine that is currently pronounced identically with
heroin in the major dialects. As it happens, Japanese has borrowed that
word also. (Given the possibilities, it seems clear from the Japanese
pronunciations that both words were borrowed from English rather than another
language.) However, rather than borrow the same pronunciation, the Japanese
simply adjusted the pronunciation of the word for hero that was also borrowed
from English and written hirô. Hence, the English homophones
heroin and heroine correspond to the Japanese heterophones
heroin and hiroin, respectively.
I should add that Japanese is generally very tolerant of homophones. It is
true that in most cases, native homophones are not homographs -- they are
distinguishable in writing because they typically contain at least one
different kanji. When words started to be borrowed from European languages,
they originally had two written forms. One was a ``phonetic'' representation
(which linguists prefer to call ``phonemic'') using the katakana syllabary; the
other form, using kanji, was constructed in the manner of new native coinages.
Eventually, the Japanese stopped constructing kanji versions and used katakana
exclusively for new foreign (i.e., European-language, and eventually
mostly English) loans. Homophones in foreign borrowings, therefore, are
indistinguishable (are homographs), unlike native homophones. Nevertheless, I
don't discern any great effort to avoid homophony. In fact, this entry was
only constructed to support the entry for the Japanese
suchîro, which represents
a Japanese homophone pair borrowed from an English homophone pair.

quantity in square brackets is being raised to the one half power
-- square-rooted.
- herpes
- A term for a variety of chronic viral infections that cause recurrent skin
sores.
The Latin word herpes is derived from the
Greek epsilon-rho-pi-eta-sigma [in beta code: e(/rphs
, genitive
e(/rphtos
masc.] and originally referred only to herpes zoster (vide infra). The Greek
term occurs at least twice in the Corpus Hippocraticum, viz. in the
Prorrheticum (2.11) and in the fun-to-read Aphorisms (5.22). It is derived
from Gk. e(/rphw
, `to creep.'
- Herpes simplex I and II
- Viruses that cause oral, anal, and genital ulcers. It used to be that
herpes simplex virus I (HSV-1) was much more common in oral ulcers, and HSV-2
more common in anal and genital ulcers, but perverted sex has mixed the two
up some.
- Herpes zoster
- The virus that causes that shingles. The New Latin name combines the
Latin word herpes (q.v.) which in origin referred
only to shingles, and the Greek zoster,
meaning `girdle.' You know, Aphrodite had a girdle that made her irresistible.

- There ought to be a word like this meaning different spellings of the same

spelling.) Cf. heteronyms.
- heterointerface
- An interface between materials of different bulk composition. A
heterointerface and a heterojunction
are the same thing, but if you talk or write of a heterojunction you imply that
you're interested in its electronic transport properties, whereas using the
word heterointerface suggests that you are concerned with other
properties (mechanical, or electronic structure properties, say).
- heteroclite
- In its original sense, in both Greek and Engish, it was a grammatical term
meaning `irregularly inflected.' I guess that's not such a useful word in
ordinary English discourse. Instead, it is now mostly used in the figurative
sense of abnormal or anomalous.
- heterojunction
- An electronic junction between materials of different bulk composition.
Typically used to refer to semiconductor-semiconductor interfaces such as
AlAs/GaAs, and to distinguish them from homojunctions. See also heterointerface.
- heterological
- A word that does not describe itself. Examples: monosyllabic, Spanish. Is ``heterological''
heterological or homological? Professor
Gilbert Ryle, in an article entitled ``Heterologicality'' [first published in
Analysis vol. 11, #3 in 1951; reprinted in Philosophy and
Analysis (Oxford: Blackwell, 1954)], argued that we cannot rightly ask
whether heterological is heterological. Hah! I just did it!
- heteronyms
- Words with identical spellings but differing in meaning and probably
in pronunciation. If they differ only in pronunciation, they're likely just
different pronunciations of the same word. If they differ in meaning only,
then you'll probably get your meaning across more clearly if you call them
homographs, it being assumed (unreasonably, to be sure) that different words
with the same spelling are pronounced identically. If they do have
different meanings and the same spelling and pronunciation, of course, they
might not be homographs but simply different meanings of one word. How to tell
the difference? We'll be examining that question eventually.

- HF
- Hardwood Floor[ing|s]. An abbreviation used in the real estate business.
Some people really like it, and some people figure they'll only cover it with
rugs or carpeting.
The shine on a hardwood floor can get scuffed away over time, or foam may get
stuck to it from years under a carpet. Typically it's not so bad that you
can't hire someone to come in and refinish it to look like new.
Do not mistake laminate for hardwood. Laminate is a kind of plywood sponge. A
few hours under standing water, and the stuff begins to look like the Pillsbury

- HFC
- Hybrid Fiber/Coax. The standard HFC
architecture uses fiber to carry video from the headend or central office
(CO) to the optical node serving a
particular neighborhood, where it is converted to an electrical signal
sent downstream via one of the (typically four) coax lines served by that
fiber line. Each coax is multiplexed, so multiple individual customers
have drops for packets. Multiple services (phone, video) are carried on
the same coax and separated by a service unit at the customer site.

(1983), Steve Martin plays Dr. Michael Hfuhruhurr, the world's greatest brain
surgeon. Steve Martin, who co-wrote the script, seems to have a thing about
brains that are absent (The
Absent-Minded Waiter, 1977; The
Jerk, 1979) or misembodied (All

In Roxanne (1987) he plays
C.D. Bales, the Cyrano de Bergerac character
whose eloquence is borrowed by Chris McConnell, a pretty face in front of an
empty skull, played by Rick Rossovich.
A number of Martin's routines have to do with

The Roman god Mercury, typically depicted with winged feet (depictions do often
include toes, though), was the god of thieves and translators, so hermeneutics
was named after him (his Greek name is Hermes), as
have a number of newspapers, including the San Jose Mercury.
Hatters once used mercuric nitrate to soften and shape felt, poisoning
themselves in the process. Hence the term ``mad as a hatter,'' immortalized by
Lewis Carroll:

- HH
- Postal code for Hamburg. The second aitch in the code probably refers to
the fact that it was a Hanseatic city, though in principle it might refer to
the fact that it's a port (see HB entry for Bremen).
Like Berlin (BE), Hamburg is both a single urban
district (including, in Hamburg's case, two nearby islands) as well as one of
the sixteen states (Länder) of the German Federal Republic (FRG). [Like most of the country information in this
glossary, Germany's is at the domain code .de.]
Hamburg is the second-largest city of Germany (after Berlin) and the
second-smallest state (before Bremen). Its area is 755.3 sq. km. and its
population (1,593,000 in the national census of 1987; 1,704,700 as of January
1, 1998).
Hamburg, Germany's largest port, is fifty-plus kilometers up the Elbe River
from the coast, and traditionally benefitted from traffic along the Elbe in
parts of northern Germany. During the period of the two Germanies, Hamburg
in West Germany lost trade from those regions, which lay mostly in East Germany
(GDR), and compensated to some extent by cultivating
business with Scandinavia.

- HHI
- Herfindahl-Hirschman Index. A measure of market concentration, defined
as the sum of the squares of the market shares (in percent).
Thus, perfect monopoly or monopsony has an HHI of 10,000 and a market
shared equally by n competitors has an HHI of 10,000/n. The HHI has the
natural property of increasing with any binary change in market share that is
intuitively regarded as concentration:
Any binary transfer of market share--i.e., any transfer of market share
involving only two market participants, increases (decreases) the HHI value
when market share shifts from the smaller to larger (larger to smaller)
market participant. Moreover, any (general) change of market share can be
decomposed into a sum of such binary transfers. However, more complex
redistributions of market share are valuated by the HHI in ways that may not
coincide with intuitive expectation. For example, a market dominated by four
equal competitors has an HHI of 2500. If three of those competitors lose
market share to a very large number of small businesses as well as to the
remaining large competitor, the HHI may remain at 2500 with one large business
holding almost half the market share.
In deciding whether to challenge a horizontal business merger (under section 7
of the Clayton Act), the DOJ and FTC consider various factors, including ease of entry
and concentration trends in the relevant market, financial condition of firms
(an unmerged company that soon fails will not prevent market concentration),
etc.
Nevertheless, the starting point for analysis is the HHI. Under DOJ-FTC
guidelines, a market with pre-merger HHI below 1,000 is regarded as
unconcentrated, and the merger is unchallenged. Note that
HHI < 1000 means that there are at least ten companies, and that
no single company can have a market share exceeding 31.62%; if the pre-merger
market is dominated by two companies (with market shares near 23.6%), their
merger can double the HHI to near 2000.
If pre-merger HHI is between 1000 and 1800, the industry is considered
moderately concentrated and will usually be challenged only if it is expected
to increase HHI by 100 points or more.
A market with HHI exceeding 1800 is considered highly concentrated; mergers
that increase HHI by 50 to 100 then ``raise significant competitive concerns.''
In any case where a leading firm has market share exceeding 35%, merger with
a firm having as little as 1% share may be challenged.
All that said, since the 1980's there's been substantial shift in legal
thinking on what constitutes monopoly power, with a deemphasis of raw size
concerns and a greater concern with how markets work, and in particular on
whether customers are deprived in some way relative to the prices and choices
that would be available in a less concentrated market. Still, all those
what-ifs are harder to measure than market share.
The formulation of the HHI implies that square of market share is a proper
measure of market power. According to
Metcalfe's Law, the value of a network varies similarly.

- Higher Heating Value. The total energy released by combustion of a fuel.
This includes the ``latent heat of vaporization'' of the water, which goes not
into heating but into changing the state of water in the fuel. This is quite
significant for wood fuel. The ``lower heating value'' excludes the latent
heat, and is often a more appropriate measure of heating value for good reasons
to be explained at the LHV entry.
For wood and natural gas, latent heat of vaporization is the most important
component of the difference
between energy released by a combustion and heating done by it. Of course, the
thing most effectively heated by combustion is the exhaust gas, and the
efficiency of a furnace is mainly a measure of how effectively the exhaust gas
is cooled -- i.e., how much of the ``heating value'' is saved from
direct loss to the environment in exhaust. (Some of the heating value is
emitted as radiation during the reaction, and may never go into the reaction
products.)

- hidalgo
- Spanish, `of noble descent.' (It also has
the usual transferred senses of `noble' in the modern sense.) The only reason
I mention it is because of the cool etymology. It's a contraction of hijo
de algo, `son of something.'
Rev. Jesse Jackson used to go around (still does, for all I know) getting
schoolchildren to repeat ``I am somebody.''
The word hijo (`son') comes from the Latin
filius with the same meaning (source of the English word filial).
(Interesting, and not really surprising, that filius is one of those
words with a distinctive vocative form differing from the nominative:
fili. For more on that, see the entry for Brute.) In Latin, a filius terrae,
literally `a son of the earth,' is an expression meaning `a nobody' or `an
unknown person.' A similar Latin word, filum (`thread,' compare
English filament) became hilo in Spanish. For more on the
f --> h sound shift, see the
Spanish entry.
- hidden layer
- In a layered neural-net structure, any layer

- hiel
- Spanish noun meaning `bile,' from the
Latin fel (gen. fellis). Spanish also
uses the Latin word bilis in its unmodified form, which yielded
French, then English, bile. Strictly
speaking, fel was a gall bladder, and bilis in Latin was the
bitter fluid (bile) excreted by the liver and stored in the gall bladder. So
say Lewis and Short at their bilis entry but
not at their fel entry. It seems that at a very early point, the
meanings became confused, and fel at least was widely used metonymically
or just loosely for bile. Spanish preserves both terms in the common sense of
`bile.' Before you panic that Spanish vocabulary has stolen a march on
English, recall that English has the Germanic word gall (why isn't this
a French word?). In fact, gall is cognate with Latin fel and
Greek cholê, chólos. (The latter is
the source of yet another English term, choler, which was popular into
the eighteenth century and can still be found in classic literature. There,
heave a sigh of vocable relief.) It might be that gall (Galle in
Modern German) is cognate with yellow (gelb in Modern German).
If so then gall is related to Latin helvus, Greek
chlôrós, and the gall bladder was named for its choler,
errr, color.
Okay, let's do some more on the Spanish words. There's a tendency for
bilis to be used as a technical or physiological term. Thus, a gall
bladder is una vesícula de bilis. Conversely, hiel is
used in nontechnical Spanish usage, where it can mean `bile' in the narrow
sense, or something bitter. The latter sense is implied by the verb
helear, which means `to make bitter,' normally in the fairly literal
sense of `adding a bitter ingredient.' It's not a very useful word, except
possibly for Spanish-speaking karela-eaters (living in Kerala, I imagine). The
common verb amargar (related to amargo, `bitter-tasting') means
`to make bitter, to embitter' and is frequently used in metaphorical senses.
Hiel is also used simply in the sense of `bitterness.' This is
particularly common in belles lettres (or is that lettres
bilieuses?).
There's a common proverb no hay miel sin hiel, literally `there's no
honey without bitterness.' This can be compared with the English proverb,
``too many cooks spoil the broth.'' Well, I said it could be compared -- I
didn't say it was comparable. Another one is ``No bees, no honey; no work, no
money.'' The one I learned was ``el que quiere celeste, que le cueste,''
literally `he who wants light blue [the sky], let it cost him [work].'
Miscellaneous paragraphs follow. Sometimes you want to mention
something, but you don't want to interrupt the flow, you know? And then it's
too late.
Spanish nouns derived from Latin neuters generally become masculine. (There is
no neuter gender in Spanish. The Inquisition, you know. And Opus Dei.) Quite
interestingly, although fel is neuter, the derived noun hiel is
feminine. These things befall in the best of families, but more often in
linguistics than zoology. Perhaps the
gender change was due to the
influence of female bilis, or maybe el hiel (`the gall') just
sounded too sing-songy.
There's an idiom sin hiel. If the
phrase makes no sense in context, you can understand it as `excellent.'
- hielo
- Spanish noun meaning `ice,' from the
Latin gelu. It's related to the verb
helar, q.v. That verb
undergoes a stem change (someday we'll have an ablaut entry, but today
ain't someday), on the same pattern as pensar (`to think'). Compactly
stated, all present indicative, present subjunctive, and imperative forms,
except for first- and second-person plural conjugations, substitute -ie- for
-e-. (Otherwise -- which is to say in first- and second-person plural forms,
in periphrastic tenses, and in the rest of the synthetic ones -- there's no
stem change.) Hence, hielo also means `I freeze.'

- Hi-Fi
- HIgh FIdelity. Describes sound reproduction; ``high-fidelity'' sound has
high fidelity to the original. Back in the 1950's and 60's, the days when
vinyl and open-reel ruled, ``Hi-Fi'' was used as a
noun for a record or tape player or a combined unit, maybe with a radio. We
had a Grundig with three or four short-wave bands. Because it was an expensive
piece of high-tech equipment, and most people weren't yet accustomed to paying
more for less, it had to come in a monstrously large piece of wooden furniture
that was mostly hollow.
``Hi-Fi'' as an adjective for sound equipment is almost as superfluous as
``electronic'' to describe a computer. The term was used by our parents to
describe their status-competition toys. In the 1970's when we started buying
decent equipment of our own, we discarded (i.e., the marketing people
decided that we would discard) the now old-fashioned term Hi-Fi. The radio
lost its speaker and output stage (amplifier) and became a tuner. The record
player lost its amplifier and speaker(s) and became a turntable. You combined
one or more of these items with an amplifier and a couple of loudspeakers and
you had a ``component system.'' The components had different brand names on
them. They started to come from Japan; soon they all came from Japan. A
turntable that came in a single box with an amplifier (what an innovative
concept!) was a stereo. Often the stereo came bundled with a radio tuner. In
the seventies you could get an old-style combination: a stereo with radio tuner,
plus eight-track or cassette or (rarer) both, in a ``compact'' unit.
In the late 90's or so, the old-fashionedness of the term now bleached out by
three decades' lying in the cold sun of the linguistic scrap heap, ``Hi-Fi''
has been dusted off and pasted onto some CD players.
Since the download of high-fidelity audio data requires high bandwidth or
patience, webpages now often offer a Lo-Fi option.
- HIGFET
- Heterostructure-Insulated Gate Field Effect
Transistor. This seems to be a Honeywell specialty. About halfway
between a MESFET and a
MODFET.
- high-concept
- High-nonsense.
- high rate of speed
- This is highly technical police language. I'm afraid you wouldn't be able
to grasp it. You'd probably think it means something like `high speed' or
`fast.' Yeah, right. Let me lay it on ya': it's traversing a given quantity
of distance during a short interval of time, relatively speaking. You'll
probably want to retreat to your cage and think it over a while.
- high-ratio mortgage
- A mortgage loan on a large fraction of the value of a property (i.e.,
a mortgage loan with a high L.T.V. ratio). In
Canadian practice, where
high-ratio mortgages are required to be insured, that is defined as a loan
exceeding 75% of the lending value of the
property.
- highside
- To have your bike fall over to the outside of a curve. Noun and verb and
unpleasant.
- hight
- A neglected useful word with the meaning of ``is called by the name
of.'' So instead of saying ``I am Red'' (which might be interpreted as ``I am
red'') or ``I am called Red'' or ``you can call me Red'' (with even greater
ambiguity) or ``my name is Red'' (a bit too formal), you can say directly, and
without leaning on the passive voice: ``I hight Red,'' which has just the right
tone (plus a bit of mystery right now). Obviously, it's a cognate of German
heißen.
Chaucer made use of the verb substantially, Shakespeare rarely. Twain embraced it in his Tale of a Connecticut
Yankee in King Arthur's Court (1889). [The action in that story is set
mostly in the sixth century, but the language is Modern English colored with
bits of Elizabethan (Early Modern English) archaisms.]
Over the centuries, there has been considerable confusion regarding the
conjugation of this verb, with the vowel wobbling about and the parts of the
verb interchanging. For this reason, it is clear that the verb should now be
regularized: hight, highted, (have) highted, highting. See also contemn and clepe.
C.R. Haines uses hight in his translation, for the Loeb Classical
Library, of the correspondence of Fronto. Specifically, in the third paragraph
of the first letter -- a somewhat chastising letter from Fronto to his former
student Marcus Aurelius, designated successor to Caesar Pius. (In this
connection, it's amusing to read the so-called Meditations of Marcus
Aurelius. The first section is a list of acknowledgments, and around the
middle of the list, Fronto has his paragraph and a carefully measured-out
teaspoon of praise.) Haines uses the construction is hight
[sic], so we may take the publication year of that volume (1919) as a
convenient date marking the death of this verb, before its resurrection in this
entry.
Very possibly, it is not accidental that the word occurs in this particular
paragraph. The paragraph is about word choice -- beginning with Cicero's and
going on to critique that of his correspondent Aurelius. According to Fronto
(in Haines's English): ``Wherefore I commend you greatly for the care and
diligence you shew [sic] in digging deep for your word and fitting it to
your meaning. But, as I said at first, there lies a great danger in the
enterprize [sic] lest the word be applied unsuitably [pause here and
reflect] or with a want of clearness or a lack of refinement, as by a man of
half-knowledge, for it is much better to use common and everyday words
[volgaribus et usitatis] than unusual and far-fetched ones [remotis
et requisitis], if there is little difference in real meaning.'' I am in
perfect concord with this sentiment. The early Loebs are notorious for their
archaic English. To judge by his 1889 work
Christianity and Islam in
Spain (756-1031), Haines was not normally quite so old-fashioned. (He
did use shew and show verb forms in about equal numbers in the
1889 work, however, and by that time shew was distinctly a minority
usage even among British writers. Then again, even in 2007 I know a Latin
teacher in England who still writes shew.)
In the particular case of Fronto, however, the archaizing is probably
appropriate, since he was deeply conservative regarding language and
literature. Though born around 90 CE, he hated the modernism of people like
Seneca, and only cared for the old republican writers. One even gets the
impression that his praise of Cicero was grudging. Fronto's use of the variant
volgaribus (see above) instead of the now-standard vulgaribus is
probably an instance of his preference for old usages. (In the original
manuscripts, of course, there was no graphical u/v distinction, so these words
were written uolgaribus and uulgaribus.) At least, -uus
nominatives could be and usually were written with -uos until the Golden Age
(70 BCE-18 CE).
One thing obvious from Fronto's letters is that he liked to pile on the words,
apparently to show off that he knew them. The reason that one obtains that
impression is that, quite frankly, the supernumerary words often added little
of significance and just reduced precision, accuracy, and overall correctness,
so to speak.

- higo
- Spanish for `fig.' Pronounced like
ego in English, except that the e is of shorter duration, the g is
articulated at the epiglottis rather than the palate, and the o isn't rounded,
but other than that it's all the same sounds.
The English word fig and the Spanish word higo are both derived
from Latin ficus, and both show the revoicing
of the cee. (The letter c in Latin is essentially a gamma that lost its
voicing. If you think I'm gonna explain that one again, you gotta'nother thing comin'.) The eff and aitch sounds are closely
related. This can be seen in Japanese, where the syllables associated with
ha are hi, fu, he, and ho. (Note, though,
that the eff there is bilabial, represented in the IPA by the character phi.) The eff/aitch similarity
can be seen in English, where the original aitch-like /x/ or /ç/ sound
still found in Scottish loch evolved into eff (rough, tough) or
disappeared (high, nigh). In Spanish, a number of Latin initial eff's became
aitches, and aitch is now silent. Other examples: hacer, `make, do,'
from Latin facere; herir, `injure,' from ferire;
hierro, `iron,' from ferrum; hijo, `son,' (cf.
hidalgo) from filum; horno,
`oven,' from furnus; humo, `smoke,' from fumus.
The word higo is used figuratively in Spanish to suggest something
small, somewhat as in the English expression ``I don't care a fig.'' However,
in Spanish it is used more, uh, figuratively, if you catch my drift.
- HIH
- {His|Her} Imperial Highness. Abbreviates the title used in English for
members of the Japanese royal family.
- Hi -- it's me!
- Just consider the alternatives.
- HILAC
- Heavy Ion Linear ACcelerator.
- Hi-Lo
- A genre of writing that comprises both fiction and nonfiction works. The
name stands for HIgh interest and LOw difficulty. Hi-Lo writing is aimed
adult-like readers with child-like reading ability. The ``high interest''
subjects of this genre are chosen to appeal to people who are beyond normal
elementary-school age and likely to be bored by the sort of Dick-and-Jane
narratives found in introductory readers. To be perfectly fair, a teenager
who only reads at an elementary-school level is nevertheless likely to be more
sophisticated than the average younger reader.
The lives of professional athletes are popular subjects of Hi-Lo. This strikes
me as ironically appropriate, though there are, uh, many exceptions.
Cf. El-Hi.
- HIM
- Health Information Management.
- Himmel
- This is a German noun, and it can be translated into just about any
European language by a single word, but for English you need two words: `sky'
and `heaven.'
- Himmelgucker
- A German fish name roughly roughly translatable as `sky watcher.' It's the
name of the family Uranoscopidae. The English common name is
star-gazer, and German also uses a parallel name as a synonym:
Sternseher.
- HIMEZ
- High-altitude Missile Engagement Zone. Surface-to-Air missiles.
See differential definition at the weapon
engagement zone entry of the DOD's online Dictionary of Military

- HIMI
- Heard Island and the McDonald Islands. See .hm.
- HINA
- Hindus In North America. A pun on the Hindi word hiina, `lost,
abandoned.' There seems to be a penchant for irony in the construction of
these initialisms.
Cf. ABCD, NRI.
- hindcast
- A forecast of past events or conditions based on events or conditions in
the more remote past. The term is used primarily in weather and climate
research, as a way to test predictive models. (Hence the alternate term
backtest, although this term is preferred by econometric and market modelers.)
- hindcasting
- The making of hindcasts, q.v.
- hindi
- The Turkish word for `turkey.' Wonders never cease.
Babahindi is a `turkey cock,' and baba is one of the words
meaning `father.' (Internationally, of course, ata is better known.
Both words, along with cet [`grandfather'], have a scattering of
generalized senses like `ancestor, forefather, elder.') There are many
compounds beginning in baba, including babaanne (`paternal grandmother'
-- so that's what the Beach Boys were singing about!), but a similar
construction for any other bird does not seem to be common. For example, the
peafowl is tavus, and the peacock and peahen are tavus kusu and
disi tavus, respectively. (Please mark your screen with a cedilla under
the s in kusu and in disi.) A drake is an erkek
ördek (literally a `duck cock') and a gander is an erkek kaz.
A turkey buzzard (more commonly called ``turkey vulture'' outside the US) is a
``hindi akbabasι.'' I assume this is a loan translation rather
than a coincidence; akbaba means `vulture.'

- Health Insurance Portability and Accountability Act. Passed by the US
Congress in 1996. Administrative reforms phased in 2000-2003. Also known as
the Kennedy-Kassebaum bill, it was originally introduced with the intent of
assuring some continuing health insurance coverage for employees immediately
after they leave a job. In a concession to the insurance industry, an
``Administrative Simplification'' section was added, intended to save money by
requiring standardized identification, diagnosis, and treatment codes, and
standard electronic formats for records and transactions.

Precision PARallax COllecting Satellite. (Ordinarily, I might insist on a
hyphen between High and Precision, but I'll let it go this time
because (a) the satellite was also high and (b) it's a cool
backronym honoring a great ancient astronomer
instead of some odd mythical character.) Hipparcos, an
ESA mission, was launched in August 1989 and
charted stars until March 1993. Its ``main instrument generated the Hipparcos
Catalogue of 118,218 stars charted with the highest precision. An auxiliary
star mapper pinpointed many more stars with lesser but still unprecedented
accuracy, in the Tycho Catalogue of 1,058,332 stars. The Tycho 2 Catalogue
[based on a reanalysis of the original data
using
improved reduction techniques], completed in 2000, brings the total to
2,539,913 stars, and includes 99% of all stars down to [apparent] magnitude
11.''
That's almost 100,000 times fainter than Sirius, the radio satellite, errr,

acetic acid), 2-benzamidoacetic acid, and phenylcarbonylaminoacetic acid.
Various of those are official. Maybe it's easiest just to remember the
Chemical Abstracts registry number (CAS 495-69-2). Okay, maybe not.
In German, it's Hippursäure, Benzoylglycin, or
Benzoylglykokoll. The interesting name comes from the Greek
hippos (`horse') and ouron (urine). (The German word
Säure, cognate with English sour, means `acid.')
Spanish and French
also have ácido hipúrico and acide hippurique,
resp.
It's commonly found in the urine of herbivores and, as you can probably guess,
it was first identified in the urine of horses. It's formed in the kidneys by
reaction of benzoic acid with the amino acid glycine, and it's a way that
herbivores get rid of excess benzoic acid in some plants. Hippuric acid
normally occurs only in trace amounts in humans and carnivores.

- Mes de la herencia hispana. I figured I'd mention it because of the
novelty of its running from September 15 to October 15, instead of coinciding
with a calendar month. Examples of the latter are collected at the awareness months entry.
Here's something geographically
numb-brained from the US Census Bureau:
In September 1968, Congress authorized President Lyndon B.
Johnson to proclaim National Hispanic Heritage Week. The observance was
expanded in 1988 to a monthlong celebration (Sept. 15 -- Oct. 15). America
celebrates the culture and traditions of U.S. residents who trace their roots
to Spain, Mexico and the Spanish-speaking nations of Central America, South
America and the Caribbean. Sept. 15 was chosen as the starting point for the
celebration because it is the anniversary of independence of five Latin
American countries: Costa Rica, El Salvador, Guatemala, Honduras and Nicaragua.
In addition, Mexico and Chile celebrate their independence days on Sept. 16 and
Sept. 18, respectively.
There used to be a Smithsonian
Heritage Months page where, at least during Hispanic Heritage Month, you
could find a link for ``evento calendarios,'' which was apparently intended to
be Spanish. In Spanish, it means `calendars
event' -- i.e., the event having to do with calendars.
They've
fixed that, but their bilingual stuff is still basically in English and
translated English.
In passing, I should note that the homepage of ``Smithsonian Education'' is now
set up with links based on who you are rather than on the information you want.
The who-you-are approach works reasonably well for toilets, but the only thing
it does well for information is insult. It's like the old ``Women's Section''
of the newspaper: tell us who you are, and we'll tell you what you want to
know, dear. University homepages make the same offensive assumption. You want
the Chemistry Department? Please tell us if you are staff, student, or

The term natural history ought to give you a hint of that. It comes
from the Latin historia naturalis. That was
the title of a sort of compendium of universal knowledge compiled by Pliny the
Elder, and for him natura was a little more inclusive than our
nature, which deserves its own entry, eventually. For now I'll just
mention that like Linneaus in the eighteenth century, Pliny dealt not just with
the animal and vegetable but also the mineral kingdom, both wild (as found `in
nature') and domesticated (dyes and other technology), and also the weather,
and other stuff. He really wanted to cram all knowledge into his encyclopedia,
and at 37 books it is believed to be nearly complete, but curiosity killed that
cat. He died in A.D. 79 when he went to investigate the volcanism of Mount
Vesuvius, which erupted and covered Pompeii and Herculaneum. (He succumbed to
toxic gases on the shore of the Bay of Naples.)
Histôria was a term borrowed from Greek, meaning `investigation,'
so natural history is the investigation of nature.
It was only gradually that the sense of the word historia (apart from
special contexts like historia naturalis) became specialized to the
investigation only of past human events.
The Greek histôria was based on the verb histôrein,
`to inquire,' related to the noun
histôr, `learned man.' No, no, his doesn't mean `man'
here. (If anything, *-tor does; it's an element in archaic Greek men's
names, such as Nestor, Hector, and Mentor in Homer, and in
no women's names that I can think of. That would make story, derived
from history, the more purely gendered term. Make of this what you
will, but leave me out of it.)
Histôr is generally agreed to be a suffixed form *wid-tor
of the common Indo-European root *weid-,
meaning `to see.' The same root also led to the Greek words eidos
(`form') and idea (`form,' `appearance,' and `idea'). (Hence Plato's
``idealism'' was his
``theory of the forms.'')
The University of Kansas serves a number of history resources such as
the Virtual Library page for History and a linked Index of Resources for Historians.
(That means that if you're not a licensed historian, you're not allowed to
use them. Stay AWAY!)

referred to as ``HIT.'' A thrombocytopenia mediated by an immune response to

is HIT, and warrants immediate discontinuation of heparin therapy.

- HLN
- HeadLine News. The sister-station of CNN. I was going to write that HLN
is now a ``sealed acronym,'' but I
realize now that it's actually a subtle XARA. (A
XARA is A Recursive Acronym.) It's 2013, and since at least September of 2010,
whenever I've read an expansion of HLN, it has been ``HLN, formerly known as
Headline News.''
Properly, that should be written ``Hln, formerly known as headLine News.''
It's a wasted opportunity, of course. They should have called it
TCNNFKAHLN (The Cable News Network Formerly Known
As HeadLine News). And maybe they will. It seems to get some kind of
rebranding every few years. It was launched as CNN2 in 1982, was Headline News
1983-1989, HN 1989-1992, Headline News again 1992-1997, CNN Headline News
1997-2007, and HLN since then. During the HN era and the first year or so of
the HLN era, ``Headline News'' was regularly used appositively. Therefore,
while it is fair to identify it as ``HLN, formerly known as Headline News,'' it
is preferable, because ridiculous and accurate, to write ``HLN, formerly known
as HLN, Headline News.''
For most of its existence, it has provided what ``headline'' implies: a
condensed version of the news, repeated on a 30-minute loop. It was like the
old WINS 1010 AM radio station in New York, which used to repeat, frequently:
``you give us twenty-two minutes, we give you the news.'' (Well it
sounded like a comma splice.) The loop actually
repeated exactly three times per hour, but they wanted you to show up early and
hear the final two minutes of ads from the previous cycle. I would foil them
by rehearing the weather report instead.
Since 2005, the once and future Headline News has shifted toward another kind
of content strongly associated with headlines: tabloid programming. I believe
they're now featuring two hours of Nancy Grace (``television's only justice
themed/interview/debate show for those interested in the breaking news of
the day'') twelve times daily. Notice that they say ``for those interested
in the breaking news.'' Even they aren't claiming that it's always
breaking.

- Horace Mann School. According to
the homepage, ``Horace Mann is a co-educational college preparatory day school
enrolling students in Nursery through Twelfth Grade. Among the top independent
day schools in the country, Horace Mann is best known for a superb academic
program that draws talented young people from three states and as far away as
50 miles.''
Horace Mann, as you probably realize, is also the name of a person. Horace
Mann (1796-1859) was an early advocate of free universal public education. He
was known as the ``father of the American public school,'' but that's a lot of
syllables; his friends probably called him ``Horace.'' (Even though ``Horace''
is disyllabic, it's practically as atomic as ``Paul.'') He was elected the
first secretary of the Board of Education of Massachusetts when that was
founded in 1837. The Horace Mann School traces its history back to the Horace
Mann Lincoln School, founded in 1887 and described today at our HML entry.

- Horace Mann-Lincoln School. A private New York City coeducational school
founded in 1887 as an adjunct of Teachers College
(TC). The official name was ``Horace Mann Lincoln
Institute for School Experimentation'' (HMLI), although making anything
official or regular is probably anathema. (I assume you know who Lincoln was.
Horace Mann is described a little bit at the entry
HM, the initialism preferred by the school in its
current incarnation.)
HML was a progressive school, and after
John Dewey joined the TC faculty in 1904,
it only got more progressive. The school was also politically ``progressive.''
It may have had a limousine-liberal period, but eventually the student body
came to be mostly red-diaper babies. The philosopher John Searle, who attended
HML in the 40's, recalled in
this
1999 interview that, as a mere socialist, he ``was sort of the class
right-winger of the ninth grade.''
``The Horace Mann
School for Boys moved to Riverdale in 1912, and during the 1940's, severed
formal ties with Teachers College and became Horace Mann School. The HM School
for Girls remained at Teachers College through the 1940's.'' I read somewhere
that that closed in 1948, and that its old building is now
New York's P.S. 125.

native city, Stockholm. Perhaps the reason for the resemblance between that
city's Latin name and

in the thirteenth century. On the other hand, for a long time the place was

complexes, the highest occupied state (a/k/a orbital) is (centered) on the
donor complex and the lowest unoccupied state (the LUMO, if you've done that
kind of calculation) is on the acceptor complex, so it's the lowest empty
acceptor orbital (the LEAO). So HODO and LEAO are special cases, for
donor-acceptor complexes, of HOMO and LUMO, respectively.

- HoF, HOF
- Hall Of Fame. What, you were expecting maybe ``House of Flatcakes''?
Henry Mitchell MacCracken, a chancellor of New York
University, conceived the idea of a pantheon of great Americans, and coined
the name ``Hall of Fame'' for it. It was founded in 1900 and built on what was
then the uptown campus of NYU. It opened in 1901
with 29 inductees.
A surprisingly uninquisitive Dave Blevins did not even address the question of
priority in his nevertheless interesting book Halls of Fame (2004).
It's subtitled An International Directory, and in addition to a few he
found in the US, he gamely listed HoF's in Canada and 17 other countries. (He
counted ``more than fifteen countries.'' Maybe he was running out of toes, or
maybe he just had a nagging suspicion that possibly the Irish Music Hall of
Fame in Dublin, Ireland, is not in the UK.)
According to the back cover, more than 450 HoF's are listed. I'm not going to
check, but here are some numbers I can compute easily:
HOF page counts
- US: 229
- Canada: 45 (!)
- RoW: 17
Are there disturbing signs that America's famous lead in the HoF race is
shrinking?

- hog
- An animal that ignorant city-slickers are apt to call by the technically
incorrect word pig, or a different animal altogether: a
Harley-Davidson motorcycle. The
latter is also called a hawg or hogg. Regarding the latter of the latter, see
the hogg entry. And speaking of entries...
In July 1995, a stray Vietnamese potbellied pig named Chi-Chi discovered a
shiny black hog belonging to Walter Wyatt, in the yard of Wyatt's home in Key
West, Florida. Excited, Chi-Chi mounted the
brand-new hog's front tire and tried to mate with it. Okay, perhaps it
succeeded in mating with it. Who's to say? Walter's wife Patricia witnessed
the whole thing from her kitchen and called police. The 50-pound animal did at
least $100 of damage to the object of his affections, scratching the paint and
tearing the bike's fabric cover. It must've been hot.
According to animal control officers, state law requires all unclaimed strays
to be neutered, and the owner, not identified in news reports, declined to
claim him. Many locals, including the assault victim's owner, felt that the
punishment was too harsh. I say the punishment fit the crime better than the
victim did, but Walter Wyatt said, ``His crime is an alleged sex act against a
Harley. We don't even know if that's a felony!'' A ``Spring Chi-Chi'' defense
fund raised $300, and Wayne Smith, president of the Monroe County Bar
Association, handled the case on a pro bono basis. ``The punishment
could be death or what some males may consider a fate worse than death,'' said
Smith.
What were the alternatives? A local motorcycle dealer said he might let
Chi-Chi go hog-wild in his showroom, just to get it out of his system. ``Just
a night's stay.'' One man offering to adopt Chi-Chi sent a letter to the
Chamber of Commerce. It ended ``P.S. I have a broken scooter. It's his.''
Chi-Chi was fixed and retired to a local petting zoo.
Florida seems to produce a disproportionate share of animal-related weird news.
For another example, read about the trouser snake at
CREAMER.
For more about potbellied pigs see NAPPA. Many
NAPA distributors also carry motorcycle parts.
I'd like to mention that Key Lime pie was invented in Key West, but I can't
think of a good excuse to do so. One of the factors in the creation of that
confection was the widespread use of canned condensed milk there, at a time
when it was less common elsewhere in the country. This must have been due to
Key West's isolation. Isolation was probably a factor in the siting of the
Agriculture Department's Animal Import Center at nearby Fleming Key. On July
26, 1989, six years to the day before Chi-Chi's case was heard in Key West, the
Ag department officially admitted a herd of Chinese hogs after four months of
tests at the center. The herd of 140 animals included three breeds: Meishan,
Ming and Feng-Jing. They had been purchased by the University of Illinois and
Iowa State University for breeding experiments. The breeds were described as
``unusually prolific''; their twice-yearly litters average 16 to 20 newborn,
with a record of 33. They must suckle in shifts. Most U.S. breeds have
litters of 10 to 12. (I couldn't bring myself to write ``only 10 to 12.'') I
should probably also mention the nearby Bay of Pigs. Done.

- HOH
- Hard Of Hearing. Deaf or hearing-impaired. You have to be a little bit
careful or sensitive in using these terms: there is an emotional disagreement
about the best way to educate children who are profoundly deaf: immersion in a

``Signing Exact English (SEE, q.v.), etc.].
Some terms to indicate partial hearing impairment are interpreted by those
favoring a signing focus as indications of destructive wishfulness on the part
of mainstreamers.

No, not the entire glossary.)
Also -- you know those double burgers with the pre-positioned cheese slice
between the patties? Take it out or start over.
Also, when I say ``Taco Salad, hold the lettuce,'' yes, that means I want no
cheese with it. Obviously, I meant ``hold the cheese'' and misspoke. ``It
comes with cheese'' is not an acceptable response.
BTW, it's not necessary literally to hold the cheese, just don't put it
on the food item.
- Hold the onions.
- This was a code phrase used in movies during the most severely repressive
era of sexual-content censorship (after institution of the Production Code in
1934; the onion code was popular in the 40's). The idea was that a man would
remember not to put anything on his breath that was unpleasant, or deleterious
to romance, if he planned to do any heavy breathing in the near future. It was
so well understood that it was a common joke on the radio. (More about leeks
and legalities at the PTD entry.)
Time passed, and people forgot. In Waiting
(chapter 9 -- see LBI entry), social scientist Debra
Ginsberg actually went to the trouble of explaining, as if to a child, that ``a
couple on a date early in their relationship will either both have garlic in their meals or request that it be entirely
removed from their dishes.'' At least she realized that it could go without
saying, that the latter group experiences
less satisfaction.

- HOLZ

- Holz
- German, `wood.' A common surname. Surnames tend to preserve older

Holtz was the Notre Dame football coach until the
end of
1996, when he resigned ``because it was the right thing to do.'' It was the
right thing to do because the AD wanted him out.
Wood seems somehow to be prototypical
stuff. When you try to conjure up an image
of nonspecific stuff, likely as not the image you conjure will be of wood or
clay. That's my theory, anyway. I mean, if someone says ``a fish''
out of the blue, the mental image evoked is not likely to be of a barracuda or
a zebra fish or even a mature flounder. You're more likely to imagine
something that looks roughly like a cod. It's like that. For supporting
evidence, see the HYLE entry. Another bit of
evidence is in the fact that the German word Klotz, meaning `block,' is
understood to mean a block of wood if the material is not otherwise specified.
More about that word is now at the klutz entry.

- Huron, Ontario, Michigan, Erie, and Superior. Mnemonic for the ``Great

Ontario, like the rest, is shared between Ontario and the US. It
probably seems unfair, but as it happens, Michigan isn't really a whole lake.
Michigan and Huron are two lobes of a single body of fresh water connected by
``Mackinac Strait,'' which is 3.6 miles across at its narrowest. Water flows
through the strait in both directions. The areas of L. Huron
(59,596 sq. km = 23,010 sq. mi.) and L. Michigan
(58,016 sq. km = 22,400 sq. mi.) are computed by allocating
some of the strait to each; their combined area far exceeds that of L. Superior
(82,414 sq. km = 31,820 sq. mi.), which is popularly
considered to be the world's largest fresh-water lake.
Lakes Erie and Ontario have areas
25,719 sq. km (9,930 sq. mi.) and

- homograph
- Two words are homographs if they are written the same way. Since English
spelling is not especially phonetic, there exist homographs with different
pronunciations. Here's a list of heterophonic homographs that I can come up
with offhand, plus some I added later:
- affect
- agape (adjective meaning ``wide open'' or the Greek word for a kind
of `love,' adopted in certain specialized senses in Christianity)
- aged
- are (metric area unit or second-person form of the verb to
be)
- axes (plural of axe or of axis)
- bases (plural of base or of bases)
- bass (low pitch, or fish)
- bow (part of a crossbow or part of a ship)
- buffet (verb or noun)
- chile
- cleanly (adjective [short vowel] or adverb [long vowel])
- close (verb or adverb)
- coax (two syllables as short form of co-axial connector; one
syllable as verb meaning persuade)
- commune (noun or verb)
- content (noun or adjective)
- converse (noun related to conversion or verb related to
conversation)
- convert (noun or verb)
- conjugate (verb or adjective)
- defect (initial syllable stressed in noun; second stressed in verb)
- defense (stress usually on second syllable of noun, except in
sports; in team sports, stress is initial in
both noun and verbed noun)
- delegate (verb or noun)
- deserts
- does (third-person singular of do, or plural of doe)
- dove (the bird, or the preterite of dive)
- dying (present participle of die or dye)
- effect (verb has long initial e in some pronunciations)
- entrance (verb and noun)
- Espy (the surname, pronounced ``ESS-pea'' or the verb, pronounced
``ess-PIE,'' appearing capitalized at the beginning of an imperative
sentence)
- Evelyn (two syllables as a male name,
three syllables as female; also, although the distinction is not
reliable in British English, the first e is long for a male name, short
for female)
- house
- import
- lead (metal whose name rhymes with led, or verb with the past tense
led)
- live
- lives
- minute (noun and adjective)
- mobile (noun and adjective)
- multiply (verb and adverb)
- periodic (short e and long i in the
chemical name)
- precipitate (verb or adjective)
- predicate (verb or noun)
- primer
- putter
- putting
- read (past tense or present tense form of read; rhymes with lead)
- recall (initial syllable stressed in either sense of noun; second
stressed in either sense of verb)
- refuse (the noun, with short e and accent on first syllable, and
final sibilant voice, and the verb, with none of these)
- reject (initial syllable stressed in noun; second stressed in verb)
- resent (sent again, or be resentful)
- resort (voiced or unvoiced s)
- row
- secreted (past of secrete and of secret, a transitive verb meaning
hide)
- sewer (sewage conduit or seamster)
- severer (comparative of severe and agentive noun of sever)
- singer (one who sings or singes)
- sliver (short i in most senses, long i in
textile sense)
- supposed (verb or adj.)
- tarry (delay or tarred)
- taxes (plural of tax or of taxis)
- taxis (plural of taxi, or the medical manipulation of a body part
back into normal position after an injury)
- tear
- unionized (organized into a union,
or not ionized)
- tower
- use (and abuse, reuse, ...; verb or noun)
- wicked
- wind
- winged
- wound
The pronunciation of the suffix -ate stressed or unstressed,
or with a long or short vowel, seems (when the distinction occurs) typically to
differentiate a verb (long or stressed a) from its homographic adjective or
noun. In cases like celibate or differentiate, the pattern holds
despite the absence of the verb or the rarity of an alternate form.
- homojunction
- A junction between regions of the same bulk material which differ in the
concentration of dopants. The paradigmatic example is the np diode, but a
junction between As-doped and P-doped n-Si is technically also a homojunction.
Cf. heterojunction.
- homological
- A word that describes itself. Examples: polysyllabic, English. In this
specific sense, homological has the synonym
autological (entry under construction). In
that sense, perhaps, autological may be preferrable, since
homological is also a synonym of homologous.
- HOMO/LUMO gap
- The energy difference between the Highest Occupied Molecular Orbital (HOMO) and the Lowest Unoccupied Molecular Orbital (LUMO).
- HOMO-1
- Highest Occupied Molecular Orbital, minus one. The orbital immediately
below HOMO and immediately above HOMO-2. Parallel nomenclature in LUMO+1, etc.
- HOMO-2
- Highest Occupied Molecular Orbital, minus two. Often when, in systems
with an even number of electrons, you say ``HOMO minus one,'' you really mean HOMO-2. That's
because in most approximations that use molecular orbitals, and to a very high
degree of accuracy, orbitals come in degenerate spin pairs, and by ``minus
one'' you mean down one level in energy. In the naming of orbitals this is
just a book-keeping or nomenclatural convention problem, but in Hartree-Fock calculations, it's an issue! See
the symmetry dilemma entry for moral guidance.

- History Of Philosophy Of Science. Distinguished from HPS, q.v.
HOPOS also referred to
``[t]he History of

social sciences, logic, philosophy, and mathematics. We interpret this
statement of shared interest broadly, meaning to include all historical periods
and diverse methodologies. We aim to promote historical work in a variety of
ways, including the sponsorship of meetings and conference sessions, the
publication of books and special issues of journals, maintaining an email
discussion group, and the dissemination of information about libraries,
archives and collections, and bibliographic information.''
The biennial meetings of HOPOS are also called HOPOS, or more specifically
HOPOS '98, HOPOS 2000, HOPOS 2002, HOPOS 2004 (San Francisco), etc.
Between the time when I first put this entry in (around 2002) and today (2004),

1760. It has an extremely discursive style, even for its era. The book begins
at the very beginning, with Tristram's conception, and a clock plays a pivotal
role in that beginning.
Tristram's father made a very regular habit, the first Sunday night of each
month, of personally winding a large house-clock that stood at the head of the
back stairs. The book is written as a first person narrative, and it includes
this delicately phrased report:
...it so fell out at length, that my
poor mother could never hear the said
clock wound up, -- but the thoughts of
some other things unavoidably popp'd
into her head, -- & vice versâ : -- which
strange combination of ideas, the sagacious
Locke, who certainly understood
the nature of these things better than
most men, affirms to have produced
more wry actions than all other sources
of prejudice whatsoever.
Shandy was conceived ``betwixt the first
Sunday and the first Monday in the month
of March, in the year of our Lord one
thousand seven hundred and eighteen....'' By the workings of his mother's
vice versa clause above, as they were doing the deed, she quoth, ``Pray,
my dear, have you not forgot to wind up the clock?'' This untimely question
disturbed his father, and in so doing it ``scattered and dispersed the animal
spirits, whose business it was to have escorted and gone hand-in-hand with the
HOMUNCULUS, and conducted him safe to the place destined for his reception''
thus damaging him for life.
In mid-June 2004, Blind River, Ontario, a town of 4,000 on the northern shore
of Lake Huron, had a related experience: all the electric clocks gained about
ten minutes per day against the eastern time kept in surrounding areas and by
computers and VCR's in the same town. It eventually
turned out that, in order to do some maintenance work, engineers of Hydro One
(the power utility) had taken Blind River off the Ontario power grid and
supplied the town from a local generator. That generator's frequency was
slightly higher than the usual 60 Hz.
What, you were expecting some connection with Tristram Shandy? No. This story
is only connected -- and that most tenuously -- with the
dueling time zones entry.
- Hörspiel
- German for `radio drama.' Literally, it is a compound noun correponding
to English `hear play.'
- HOS
- Higher-Order Statistics.
- HOS
- History Of Science. An academic discipline not unrelated to
HPS or HST. There's a
link to useful stuff at HSTM.
Okay, a thumbnail description: history of science is historical inquiry (now
``interrogation,'' in the pomo term) designed to
demonstrate that scientists are fundamentally self-deluded and irrational.
Because the majority of in-fashion historians of science like science
as much as they like scientists, HOS is increasingly externalist.
One of the interesting emerging research problems in this careful field of
scholarship is ``the Science Wars.'' The circumstances of the Science Wars are
the following: Working scientists (natural scientists, I mean) mostly ignore
philosophy of science because it is of no use, and ignore history of science,
as written by historians rather than scientists, because it is no good.
Time-out for an opposing opinion: Scientists dislike philosophy of science
because it exposes their unthinking prejudices, and ignore history of science,
as written by historians rather than scientists, because it is not Whiggish
and so does not flatter scientists' triumphalist fantasy. We now return you
to the regularly-scheduled rant.
People in HPS have difficulty understanding scientists' POV, because they think
that what they're doing is useful (philosophers) or competent (historians).
Occasionally, a scientist will notice the spew from HOS, point out that it's
garbage, and possibly even trouble to explain why, even though the fact is
essentially self-evident. The HOSers will respond by psychoanalyzing the
offending scientist. Occasionally the story makes it into the newspapers.
This is the Science Wars.
Okay, time for another fit of conscience. Philosophy is useful, though
not usually in a practical way, because it attempts to answer the most
fundamental questions thinking people have tried to make sense of.
Unfortunately, science deals only in approximations. Often excellent
approximations, but still not certain enough to hang a heavy philosophical
argument on. For example, Newtonian mechanics is an excellent approximation
for the reality the eighteenth century could understand, but the qualitative
aspects of that theory bore only a partial formal resemblance to the quantum
mechanics that replaced it in the twentieth century. So while Newtonian
mechanics might be highly accurate in physical terms, in metaphysical terms
it wasn't in the same universe, never mind close. Today's physical theories
are much more accurate than Newton's and explain a much broader range of
phenomena, but there is no reason to suppose that these accurate theories are
anything but sand foundations for a metaphysical edifice.
As to HOS, well, a lot of it is garbage, and a lot of it is excellent.
Because HOS is not itself a science -- that is, because it does not as a
discipline integrate regular tests of theory against experiment, there is no
very good way to cast off the ballast, and various ships in the HOS fleet are
sinking under the weight of too much pomo freight.
Taking cognizance of the preceding information, you may or not be interested
in the discipline's professional society HSS and the
fact that the largest, oldest, and probably the best respected (within-field)
HOS department in the US is the one at the University of
Wisconsin-Madison (UW), q.v.

- Nickname of character Eric Cartwright played by Dan Blocker (see IMDB entry) on the TV
series Bonanza (1959-73).
Middle son of Ben Cartwright (Lorne Greene) and brother of
Adam Cartwright (Pernell
Roberts, only until 1965) and Little Joe (Michael Landon, who later
starred as father on the treacly Little House on the Prairie;
see the IMDB entry, if you must).
The name ``Hoss'' suggested build or strength. Dan Blocker died of a pulmonary
embolism following surgery at age 43 (1928.12.10-1972.5.13).
- hot, HoT, HOT!
- Helen Of Troy. A legendary person and a forgettable 2003 TV
mini-series that uses the names of some characters from Homer's
Iliad. Some plot elements also appear to
have been inspired by that book. Helen of Troy is also the title of
a 1956 movie. In this one,
Brigitte Bardot (not yet a star) plays Andraste, a handmaiden to Helen. You
know the joke about the millihelen, right?
Incidentally, if you're ever in the land of Heinrich Schliemann or anywhere
else that German is spoken, you should be careful to distinguish phrases about
the weather or environment, such as ``es ist heiß'' (`it is hot')
or ``mir ist heiß'' (`it seems hot to me'), from statements about
internal conditions like ``ich bin heiß'' (`I am sexually excited,
I am in rut'). You wouldn't want your partner to get up and turn on the
air conditioner -- it might get very cold in the
room (das Zimmer), very fast.
- HOT
- History Of Technology, not. This cool acronym is avoided by
professional historians of technology. Instead, they use
STS and HST, always
sticking science in there, as if some technologies were not in fact
completely independent of or at least prior to science. Not serious enough, I
guess. Have a little fun! At least the professional society is
SHOT.
If you only have space in your library for one so-bad-it's-good book, please
consider A Short History of Technology, copyright 1954 (details at
self-published). It's not by
professional historians of technology either; it's by Vice Admiral Harold G.
Bowen and Charles F. Kettering. I have two bits of advice about reading it:
- Don't drink and read.
- Vacuum the carpet first. (You'll thank me when you're ROTFL.)
For a sample, read the first two paragraphs of Kettering's foreword:
This booklet is a short history of discovery and invention. It also is an
explanation of how our country became the leading industrial nation of the
world with the highest standard of living ever attained.
It tells how the nameless people of Western Europe by their own
inventions, plus those acquired from the Arabs, improved the existing practical
arts. The improvement continued until suddenly the mind of man became
emancipated from most of the century-old ideas which had been holding him back
and he became creative.

the Twentieth-Century United States. ``In June 2007 around 30 British
historians of the US gathered at the Institute for the Study of the Americas

how are they going to define ``twentieth century''? (Cf. BrANCH.)

- Hottentot
- Remember, you can't spell Hottentot without tent. Actually,
you might as well forget it, because the approved term is Khoikhoi, that
group's own name for itself, and the former term -- based on European settlers'
efforts to imitate the click sounds of their language -- is deprecated (in the
computing sense) as deprecatory.
Also, they apparently didn't use tents historically,
but more permanent structures, despite practicing transhumance (moving their
herds between winter and summer pastures). A west African friend told me (in
1982 or so) that people would ask him things like ``do Africans still live in
trees?'' But he was still kind of hung up on the colonialism/neocolonialism
thing, and it wasn't unknown for him to exaggerate. Also, he claimed that they
don't live in trees. I could be more precise with the details, but I'd rather
point out that he is now his country's UN ambassador [temporary ``permanent
representative to the UN''] and leave his and his country's identities vague.
Once upon a time, there was an African King who kept several thrones hanging
around in his grass hut palace. Then one day they all came crashing down. The
moral: ``People who live in grass houses shouldn't stow thrones.'' br>

- hot tip
- The business end of a soldering iron. Be careful.
- house
- The pronunciation of this English word is interesting: the verb has a
voiced ess (i.e., a zee sound). Voicing of
the final sibilant distinguishes noun and verb in some other instances.
(This is sometimes marked by a spelling difference, as in advice (n.)
and advise (v.), and sometimes not, as in use and use,
similarly excuse.) The other words I can come up with that look like
house and have common noun and verb uses, are grouse,
louse, mouse, and souse. All have a consistent unvoiced
final sibilant. (Touse, with voiced ess, seems pretty archaic to me,
but it tended to be a verb...) There is, on the other hand, a tendency for
-ouse words that function almost exclusively as nouns
(lobscouse, spouse, titmouse) or verbs (bouse, espouse, (a)rouse,
carouse), to have unvoiced and voiced ess at the end, respectively. But
there's an exception, if you count the verb chouse, which may not be
obsolete. Douse or dowse is
trickier, since the voiced and unvoiced verbs, spelled either way, refer to
different actions.
It is dangerous to try to draw conclusions in English based on spelling alone.
The sound-spelling correspondences, er, correlations, depend very much on the
origin. The etymologies of -ouse words, as it happens, are a bit varied and
occasionally unknown. However, I think it is useful to consider all -ouse
words as a group, because they tend to look Germanic and be interpreted
as such. (Just as deacon, from Greek via Church Latin, is pronounced
like Germanic beacon.) Anyway, I think that the pattern of voicing may
have to do with assimilation of voicing in the final consonant of the verb
inflected forms. That is, rouse, say, even if it have started with an
unvoiced ess, could have gotten a voiced ess first in the frequent form
roused. Later, the voicing would have jumped the vowel in rouses
and also appeared in rouse, in an instance of psycholinguistic reasoning
(in Sapir's sense). Nouns, and words that may be verbs but usually are nouns,
would not have been affected. House is then exceptional in a consistent way:
unlike most -ouse nouns, its plural has voicing in the root. That is, the
first ess in the plural noun houses has a zee sound, just like the
second and final ess. So it all pretty much hangs together, if one can explain
why the first ess in houses is voiced, even though it's not voiced in
similar collocations elsewhere. Probably has something to do with archaic
plurals. Uh, yes, um... we'll leave this as an exercise for the reader.
Comments above about current pronunciations tend to reflect my own (typical
mid-Atlantic) dialect. Pronunciations vary. AHD4
claims that blouse is somewhere pronounced with a voiced final ess. A
regional variation related to house is in the name(s)
Houston, q.v.
- Housman, A. E. (Alfred Edward) (1859-1936)
- In the introduction to his critical edition of Manilius, book v (1930),
the famous poet and classicist wrote:
The first volume of the edition of Manilius now completed was
published in 1903, the second in 1912, the third in 1916, and the
fourth in 1920. All were produced at my own expense and offered
to the public at much less than cost price; but this unscrupulous
artifice did not overcome the natural disrelish of mankind for the
combination of a tedious author with an odious editor. Of each
volume there were printed 400 copies: only the first is yet sold
out, and that took 23 years; and the reason why it took no longer
is that it found purchasers among the unlearned, who had heard
that it contained a scurrilous preface and hoped to extract from
it a low enjoyment.
More at the A. E. entry.
- Houston
- A city in Texas whose name is pronounced about
like ``YOU stun'' or ``HUGH stun.'' (I.e., as /'ju:st.n/ or
/'hju:st.n/, where I've represented a short-duration shwa by a
period.) There's a Houston Street in New York City;
that ``Houston'' is pronounced essentially as ``house-ton'' (/'haust.n/). As I mention at
the SoHo entry, I've heard that mispronouncing the
New York name led to the exposure of a German spy in WWII, but I've never been able to track the story down.
- HOV
- High-Occupancy Vehicle. Term used for what is really better described as a
vehicle that is somewhat highly occupied -- with more than one, maybe
more than two riders. (Unless it's a motorcycle, I think.) Less-clogged HOV
lanes are used by traffic-choked municipalities as an incentive to get
commuters to buy life-size passenger dolls. In some movie I heard about, a guy
desperate to use HOV lanes hired a prostitute off the street to ride with him.
So the streetwalker became a passenger, a ho' fo' de HOV. Sounds perfectly
natural.
There are proposals floating around to allow LEV's
in HOV lanes.

- How Many Children Had Lady Macbeth?
- A famous 1933 essay by Lionel Charles Knights, published in his

an Early Modern English phrasing of ``How many children did Lady Macbeth

Also the title of a (probably justifiably) unknown monologue (by Don Nigro,
1966) in which a woman describes how her ambition to play the role of Lady
Macbeth has led to some funny and some sad consequences.

- Most people know how to crack their knuckles but not their backs.
I discovered accidentally how easy it is:
- Sit to one side (i.e. next to the middle) of an old sofa. Ideally,
the sofa should be dusty or have loose dry dirt on top, or have threadbare
cushions filled with hardened, disintegrating old urea foam.
- Slap the middle of the sofa repeatedly.
- Without moving your legs/lap, twist your upper body sideways to lean down
to face the center of the sofa.
- Sneeze involuntarily, surprising yourself.
This method may not be very repeatable, but you won't mind.
- HO3
- HomeOwners 3 Special Form. Industry-standard homeowners insurance.
As far as I know, the absent apostrophe is standard too. The 3 refers
to the three basic kinds of protection:
- Physical damage coverage. This pays repair/replacement costs for
house, unattached buildings on the property, and personal property, and
incidental expenses for temporary alternate housing.
- Liability coverage. Pays for liability you or your household or pet(s)
may incur for someone else's bodily injury or property damage, or to defend
in court against a claim of such liability, or both.
- Medical coverage. Covers the same group as liability, but pays medical
expenses. The idea behind this is, say some knucklehead visits and walks into
your door. The medical coverage part of your homeowners insurance is a kind
of no-fault coverage that pays for an MRI scan
to see if his brain cell was damaged. It's hoped that this will take care
of sincere nuisances, up to a kilobuck or so. If that won't do, and
knucklehead wants you to pay for an intelligence transplant or for mental
anguish (oh! the embarrassment!), then he's going to have to sue or settle,
and that's where liability coverage for bodily injury kicks in. He'll
need to convince a court that it was negligent on your part to have a
door, or demonstrate that he was not already stupid before the brain trauma
suffered on your property. (And no, it's not hard to find donors for an
intelligence transplant. Plenty of people have it and never use it.)
- HP
- Helicobacter Pylori. A bacterium discovered to be extremely common
in human stomachs, which promotes gastric ulcers. Until the mid-90's,
when this was discovered, it was thought that stress and diet were the
principal etiologic factors in gastric ulcer. One clue otherwise was the
observation that ulcer symptoms decreased in some patients taking heavy
antibiotic doses. Surprisingly, in the initial stage of HP infection,
there is a temporary hypoacidity.

- HP
- Home Plate. (Baseball designation.)
- HP
- Homosexual Panic. The secret fear that one may be homosexual. Also
HD. Today's politically correct position is that
any objection to homosexuality is irrational and yet also dishonest. The idea
that those expressing such objection are reacting to the secret fear that they
are homosexual was a rhetorically useful pose (and probably also sincere; many
people easily believe sincerely in whatever they see it as in their interest,
however slight, to believe). Hence, HP was a convenient label for anyone
opposing homosexuality. This ``opposing'' phrase is vague only today. In the
1950's, and perhaps largely until Stonewall, the ``opposition'' was general --
homosexuality being widely deemed immoral, illegal, disgusting, and sick. The
label ``HP'' was applied primarily to the more vociferously or actively
intolerant.
With the liberalization of attitudes that began in the 1970's, it became
possible to stigmatize increasingly mild or circumscribed opposition to
homosexuality. In this context, a term like HP implies an implausibly
exaggerated emotion. Perhaps that contributed to the displacement of HP and HD
by the term homophobia, which has the undeniable added advantage of
sounding a bit like a clinical diagnosis.
- HP
- HorsePower. One HP is approximately 745.7 watts, and exactly 33000
foot-pounds per minute or 550 foot-pounds per second. Also 9000 mile-pounds
per day, or mile-stones per fortnight, in equally
sensible units. Here you can see some of the genius and convenience of the
English system of units: you can divide by 11 or
14 and still come out with a whole number of something. The horsepower unit
was defined by James Watt (a bit on him at the W
entry for watt).
A typical horse can do work at a rate (i.e., a power) greater than one
horsepower for short periods of time, but not for long. Astro Boy has a strength of 100,000 horsepower!
- hp
- Hot Pudding. In England, pudding is served hot. Isn't that
weird? Okay, I admit it; I made it up (the acronym
being ``hp''). I should probably also mention that pudding originally referred
to minced meat stuffed and cooked in an animal's stomach or entrails --
sausage, in other words. Hence the euphemism pud.
``If you don't eat your meat you can't have any pudding!
How can you have any pudding if you don't eat your meat?''
Another food word whose meaning has drifted is sherbet. In the
UK it still seems to be a fruit drink (now possibly
from Kool-Aid-like powder) cooled with crushed ice (historically also with
snow). In North America it refers to a frozen refreshment made from sweetened
fruit juice, milk, and an agglutinant (egg white or gelatin). Like ice cream,
it is churned while freezing, so the water crystals are small and the bulk
opaque. In Australia, sherbet still refers to a beverage, but an alcoholic one
-- mostly beer. There's a logic to this: like an iced drink, beer cools you
off fast on a hot day.

approximate an ideal HPF, which would absorb perfectly all signals below a
cut-off frequency and transmit without loss all signals above it. A low-pass

Service-learning [sic] is an innovative form of community-based
education. The word innovative in this and many other contexts
describes any old idea and means `promoted by earnest do-gooders constituted as
a foundation.' These organizations have a superior understanding of the best
ways to perform various activities that they are not directly engaged in,
because they have control over the money of a philanthropist who is spinning in
his grave. As the saying goes, ``everything is easier for the man who doesn't
have to do it himself.'' It's quite amazing that professionals could continue
for decades doing their work in the same old ineffective ways, when simple
changes, relatively inexpensive once they are funded by the federal government,
are so clearly superior. This should not be interpreted, however, as an
indication of incompetence on the part of those professionals. Rather, it is
only what one would expect from organizations that seemed to function for so
long despite the absence of strategic guidance from
suits.
Foundation-like thinking also occurs in the private sector, where it is known
as the Harvard Business School Syndrome -- the idea that a firm understanding
of general business principles is sufficient preparation to run any industry or
commerce. Extensive, detailed knowledge of a particular business is recognized
as not merely superfluous but detrimental, because it leads to small-picture

- HR
- Hertzsprung-Russell? You probably want to see the entry for the
H-R diagram.
But as long as you're here, why don't you have some tea and we can have a chat
about the name Hertzsprung. The German word Herz (the t is just
old-fashioned or variant spelling) means (and is cognate with the English word)
`heart.' The meaning of sprung is a little less clear. It can mean
leap, but it sometimes refers to a watch spring. The latter sense makes it fit
right in with the preceding entry, but I think the proper interpretation is
`sprung from the heart' or `leap of the heart.'
There are a lot of odder Herz- names that are common. Herzbach is
`heart brook.' Herzberger or Herzberg is `someone from heart
hill' or (what is implicitly the same) `heart hill.' Herzweig is
written as a bit of a blend, constructed from Herz and Zweig.
Hanks and Hodges offer `heart twig'
as a translation, but I think this is slightly, unintentionally misleading.
Zweig is indeed cognate with the English word twig, but German
does not have a common term for anything larger, like the English word
branch. Hence, Zweig covers the entire semantic and quantitative
range from twig to branch. If anything, Reis and the diminutives
Zweiglein and (rarer) Zweigchen edge in semantically from
sprig towards twig (but don't hold me to that; translators must have
license). So I would go with `heart branch.' Don't tell me this makes no
sense; what is a Harzfeld? (I mean, what does `heart field' mean?) Oh
yes, Herz can also mean strong or brave or hardy (from a cognate with
the last) or deer (think hart), but these senses are not usually adduced
to interpret compound names.
Here's an interesting biographical bit from Hanks and Hodges, s.v. Herz:
The Russian philosopher Alexander Herzen (1812-70) was given this
surname because he was technically an illegitimate child, one born of the heart
(vom Herzen). His father was Ivan Yakovlev, a Russian nobleman from a
minor branch of the Romanovs, and he had married Alexander's mother only
according to the Lutheran rite, which was not officially accepted.
Again we see how childhood trauma leads to adult pathologies like philosophy.

concerned about 460 employment-related grants awarded over the course of two
years, and the main problem found was poor record-keeping. The value of the
programs affected ran to about a billion dollars, but it was only a billion
dollars Canadian, so there's no need to lose one's head over the matter.
There's a bit more about this at the HRSDC entry
and this SEDERI entry.
This HRDC entry is a Canadian-government-related stub. If you want to help
improve this entry, you're out of luck, because this isn't Wikipedia. But I'll

High school is the last few years of secondary education. In most of the US,
it is either the last four or the last three years. The latter is often called
senior high school, to distinguish it from junior high school (JHS). Further discussion at the MS entry.
In Canada, all or many of the provinces used to offer secondary education
through grade 13, and high school would typically be the last four or five
years of secondary education -- grades 9-12 (culminating in what was called, in
Ontario, SSGD), or 9-13 (SSHGD) for those continuing to university. (In at
least one district, grades 7-8 were called ``senior public school.'')
Ontario, the last province to switch over to graduation at grade 12, did so at
the end of the school year in Spring 2003. The students graduating from grades
12 and 13 in the high school class of 2003 were called the double cohort.
Amazingly, based on original college entrance projections, this was not
expected to be a logistical nightmare. Double the number of freshmen the first
year? No problem! Twenty-five percent increase in enrollments and housing
requirements one year, then a twenty percent decrease four years later? Sure!

- HSD
- Honestly Significant Difference. The HSD is used in pairwise comparisons
of statistical samples taken under conditions to be compared. The HSD value
is a bound to be compared to the standardized range statistic. (The
standardized range statistic is just the difference of two sample means divided
by the best estimate of the sample standard deviation. Confusingly, writers
sometimes also call this figure of merit the HSD, whether it is significant or
not.)
This simple test of significance was first defined -- as a formal test -- only
by Tukey, (of FFT fame) in the 1950's. When the
HSD value is exceeded, then the assumption that two samples are drawn from a
common distribution can be rejected (at a stated significance level). When
careless writers HSD for both HSD and standardized range statistic (ideally
to be labelled Z), you can sometimes tell the real HSD from the use
of a subscript indicating the significance level (typically HSD.05
or HSD.01).
The HSD bound depends on the number of degrees of freedom, the number of levels
of the independent variable (essentially the number of different samples
available to be compared), and the significance level (alpha, the acceptable
level of type-I errors).
HSD values are computed without making any assumption about the form of the
underlying distributions. Thus, Tukey's HSD test is more general than the
widely used F test, which assumes normal distributions.

- According to this
page on official the website of the City of Toronto, ``[t]he name
HTO represents the fundamental changes that will take
place in the relationship between Toronto and its waterfront.
HTO was created by a design team led by Janet Rosenberg
+ Associates Landscape Architects (Toronto) and Claude Cormier Architectes
Paysagistes Inc. (Montreal), in partnership with the City of Toronto's Parks,
Forestry & Recreation Division. The design is based on six elements or layers:
ground planes, water, islands, expressive
horticulture [that's where your plants talk back to you, no doubt], lighting,
and beach furniture.''
Here is a relevant excerpt from The Profit of Kehlog Albran (1933-1927):
woman stepped forward and asked,
What is the strangest day?
Tuesday, the Master explained.
Further down the aforementioned webpage, there is the following explanation of
the symbol HTO: ``The winning design team for Phase I
consists of Janet Rosenberg & Associates Landscape Architects of Toronto
and Claude Cormier Architectes Paysagistes Inc. of Montreal. Together they
have created a design known as HTO. The name represents
the fundamental changes that will take place in the relationship between
Toronto and the waterfront.''
There is a relevant quote from some fourth-century desert monks, but I don't
have it handy right now. I think that HTO might be
expanded Harbourfront Toronto, Ontario, but that it normally isn't because mere
words aren't pretentious enough.
TO is a widely used abbreviation for Toronto.
Presumably the official form of the symbol is the one with the T subscripted
rather than in a smaller font, and is intended to suggest water
(H2O). Subscripts and small-caps are usually at least a little bit
inconvenient, and sometimes difficult or impossible, to insert in a printed
document, and one sometimes sees the symbol written HtO.

Here's an FAQ.
Here's the Hungarian
page of an X.500 directory.
Enrico Fermi did an estimate of the density of planets with life and
intelligent civilizations, and came up with a sufficiently high humber that
afterwards he became known for the question, ``where are they? Where is the
evidence of alien intelligence?'' [Paradigmatic form of the quote, so far as I
can remember right now.] I suppose I should mention that at the SETI entry. Anyway, in the 1940's and 1950's when he
was active in the US, there were also a lot of prominent emigre physicists --
refugees -- from Hungary. Very intelligent people like John von Neumann and
Leo Szilard and Eugen Wigner. (For others, see Hungarians In America.
There I learned that Joseph Pulitzer of Pulitzer Prize fame was born in Makó,
Hungary, and that Béla Bartók died in New York City, September
26, 1945.) So somebody answered Fermi's SETI
question: ``they are among us, but they call themselves Hungarians.''
Actually, the somebody who gave this answer was Leo Szilard. See Is Anyone
Out There?: the scientific search for extraterrestrial intelligence, by
Frank Drake and Dava Sobel (Delacorte Pr., 1992), p. 130. I should probably
have mentioned this at the France entry. Skits
involving the Coneheads were a popular feature during the early years of
Saturday Night Live, back when SNL was funny. The
Coneheads were a family of aliens trying to fit in as an ordinary family in
suburban America. To explain away any oddities
that might raise the suspicions of their neighbors (but not their
two-foot-tall, minuteman-missile-shaped bald heads, which everyone accepted as
unexceptional), they claimed that they were from France. (At the time, this
was considered so improbable as to be funny.)
One of the Coneheads' oddities was their use of stilted, unnecessarily
technical language, which sounded like a bad translation from Latin.
Consume mass quantities!
(For something similar, if imagination and memory both fail, check the ISO 9000 Certification entry.)
Another example was ``fried chicken embryos'' for fried eggs. This term was
technically inaccurate. Hens lay eggs, fertilized or not. The eggs you buy in
the store are from hens not serviced by roosters. They can't develop into
embryos, and it's pretty obvious that they haven't. We also have an
eggs entry.
Microsoft used to promote something called
Hungarian notation, which is just as relevant to this entry as anything in the
preceding few paragraphs. All Microsoft API's,
interfaces, technical articles and excuses used these conventions, which were
developed by Charles Simonyi. Basically, it's a convention governing the
initial parts of the names of variables, functions, types and constants,
classes, objects, and parameters. Here is where I'm going to place a table of
the basic prefixes, if I happen to get around to it:
...
- HUAC
- House Un-American Activities Committee.
I suppose they investigated people who didn't orient the pie slices to point at
their stomachs before eating them. And people who play soccer.
- HUAM
- Harvard University Art
Museums.
- HUB
- Historically Underutilized Business. Federalese for minority- and
women-owned firms. Come think of it, most large corporations are controlled by
minority shareholders, but not in that sense.
- HUB
- Humboldt-Universität zu
Berlin. Also HU.
- Hubba-hubba!
- Vavavoom!
How do they come up with this stuff?
- HUBNET
-
Hospitals and University at Buffalo Library Resource NETwork.
- HUC
- Hebrew Union College. ``The Academic,
Spiritual and Professional Development Center for Reform Judaism.'' Graduated
its first class of Reform rabbis in 1883. They were fêted with an
aggressively treif banquet (including clams, crab,
shrimp, and frog legs). Most of the new rabbis succumbed to food poisoning.
(Just kidding about the food poisoning. I mean, it coulda happened, but I
don't know that it did.)
- HUC-JIR
- Hebrew Union College - Jewish Institute of Religion. Longer version of the
name also abbreviated HUC. The appositive is useful
clarification; without it, I'd probably have guessed it was a school of Jewish
architecture. (They have a program in cantorial studies also.) There seems to
have been a vogue in this sort of hyphenated name within the movement:
cf. LBC-CJE.
- HUD
- Heads-Up Display. (As in displays for drivers of motor vehicles. That's
`drivers' in the sense of human operators, not drivers in the sense of
machines directly generating electronic signals to activate servos and such.
Also, I mean `motor vehicles' in the sense of self-propelled conveyors of
passenger(s), cargo, or both, and not animate
carriers of a motor disease. And by `operators' I mean ....) The term is also
used in computer games to indicate that status information (available
ammunition, scores, etc.) is continuously visible on screen
- HUD
- (US Dept. of) Housing and Urban
Development.
HUDG
- History in Universities Defence Group. A UK
group. I believe the group conceives itself to be defending history against
the shade of Margaret Thatcher. This is appropriate, since she is a historical
figure, even a historic one.
- HUF
- Highway Users Federation. A dependency support group?
- huge chocoholic
- Okay, maybe not the best choice of words.
- Huge, Victor
- A writer best known for The Halfback of Notre Dame. Something like
that, anyway.
Above the main doorway exiting the computer cluster in Notre Dame's main
library, a sign says ``LOG OFF LIKE A CHAMPION TODAY.'' You're supposed to get
that joke too. What are you, stupid or sumpin'?
- hugging
- Vide promiscuous hugging.
- Hum.
- HUMidity. It's not the heat.
I've asked around, and in Japanese there doesn't seem to be a common phrase
that would translate ``It's not the heat, it's the humidity.'' That's a
defect, because the (English) phrase is very appropriate to Japan.
- human scale
- The emblem of the 2004 Olympics in Athens was an olive wreath, called
kotinos in Greek. This was the prize in those earlier olympics. (There
were no second prizes, only winners and losers.) Officially, the wreath
represented the four values of the 2004 Games: heritage, participation,
celebration, and human scale. If those were answers on a multiple-choice test,
the question would be: ``Which of the following does not belong?''
There is much confusion about the meaning of the term human scale. It
is widely used to mean the dimension or length of a hand or a few feet. This
is incorrect. Those are the scales of monkeys and horses. The human scale is
interstellar; we just haven't arrived yet.
- humane vents
- Huh? Oh! Human Events -- the journal. ``Leading the Conservative Movement * Since
1944.'' So what is the late WFB's National
Review, chopped liver?
- humble physicist, I'm just a
- Now there's a phrase you don't hear much.
Laura Fermi recalled that the physicist Leo Szilard said to Dr. Luria of the
University of Indiana, who didn't know at what level to pitch an explanation
of his work,
You may assume infinite ignorance and unlimited intelligence.
Laura once asked her husband Enrico (see FGR,
fermi entries) why physicists were so arrogant,
but I forget his answer. It's somewhere in her biography of him,
Atoms in the Family.
- Humboldt-Stiftung
- Swedish site.
Main site in Germany.
- Hume
- David Hume was a ``British Imperialist'' who died in 1776, the year of
the US Declaration of Independence. Something like that, anyway. In his
portrait you can see he's wearing a rug more fake than a duck decoy in
mating season. Naturally, he made contributions to the
philosophy of science (no, not in specie but in kind).
- Hume-Rothery
- William Hume-Rothery (1899-1968) was a ``British Metallurgist,'' who did
science, instead of just talking about it. The eponymous Hume-Rothery rules
are an empirical guide to when two metals are sufficiently similar to be
completely miscible (form a single phase at all relative concentrations).
The rules are:
- Atomic radii no more than about 15% different.
- Pure metals have the same crystal structure.
- Atoms have similar electronegativities.
- Atoms have the same valence.
- HUMEVAC
- HUManitarian Emergency eVACuation.
- HUMINT
- HUMan-sourced INTelligence. ``Intelligence'' here is meant in the
espionage sense; HUMINT is knowledge of an enemy (or opponent, or potential
enemy, for that matter an ally that is not perfectly transparent) that is
obtained by interviewing someone who knows. Cf.
HI.
- Hummer
- Originally one nickname for a military vehicle officially designated HMMWV. Eventually, Hummer became the official name
of the civilian versions of that vehicle. In 2000, after
GM bought the right to use the name,
Hummer became the marque
name, and the earlier class of civilian Hummers became the
H1 model. In 2002, the H2 model went on sale, rather more
affordable and nearly as rugged as the H1.
The other common nickname, now used exclusively for the military vehicle
(HMMWV), is Humvee. Interestingly, a military
version of the H2 is being considered by the US
Army. The Humvee was originally intended as a combat vehicle, but has been
used for noncombat missions.
- humor, humour
- One way to classify humor is into the categories of unintentional humor
(e.g., amusing errors) and intentional humor (jokes). Behind the scenes
here at The Glossary, we are working constantly to increase the
intentional:unintentional humor quotient. Also, we're looking out for errors.
Of course, since it's surprising and amusing that we would make any errors at
all, these are instances of category I humor. We constantly check and
double-check for any mistakes. We don't want any unintentional humor to go to
waste, so what we do when we find mistakes is carefully mark them with a mental
checkmark, so they become jokes. We've been doign [sic: intentional,
ha-ha!] very well, take my word for it.
For slightly substantive thoughts on humor, see the
kill the frog entry.
- HUMRRO
- HUMan Resources Research Organization.
- Humvee
- Onomatopoeia of what happens when someone tries to pronounce HMMWV, the US military's original official
abbreviation of the vehicle which succeeded the Jeep
(another modified initials sequence). Also informally called Hummer, but that name was later made the official
name of the civilian versions. Built by AM General of South Bend,
Indiana. (Plants in Mishawaka -- one town east.)
- Hunter College
- Well, really this is about Rose Hamburger, but there is as much on Hunter
College as there is on any other topic other than Rose Hamburger. The daughter
of a department store executive, Rose was born in Manhattan on December 29,
1890. Her maiden name was Rosenbaum, so I suspected that Rose was not her
original given name, but a leaf a couple of branches further out along the
family tree informs that it was.
Normal College had been established in 1869 as the Female Normal and High
School, and held its first classes on Valentine's Day in 1870, regarded as the
official founding date of the institution and its successors. Its name was
changed to Normal College of the City of New York later that same year, but it
was still a girls' school. (A normal school, incidentally, is a school that
prepares students to become teachers. As secondary education became common,
normal schools evolved into normal colleges, and in the middle of the twentieth
century the term ``normal college'' was abandoned in favor of ``teachers'
college.'')
In 1879, the length of the program of studies was expanded from three years to
four. In 1888, the minimum age for admission, which had been raised to 14 in
1872, was raised again to 15, and Normal College was authorized to grant
baccalaureate degrees. [The first B.A. was granted only in 1892. Possibly
this is because students in the ``normal'' program were still earning teaching
certificates. The ``classical'' (i.e., nonteaching) program of studies
was only created in 1888.] Only later did the Normal College receive Regents
accreditation and state recognition of its degrees (provisional in 1902, full
recognition in 1908). Miss Rosenbaum graduated from Normal College in 1910 at
the age of 19, with degrees in mathematics and music.
(This implies that she finished in less than four years or was admitted before
reaching age 15, or simply that graduation took place earlier in the year than
admission. According to an article based on a 1995 interview, she enrolled in
1907. Then again, she explained that she never fulfilled her dream of becoming
a concert pianist because her memorization skills weren't too good. (You're
probably wondering why I'm providing this
information. It's not for you. It's because someone else out there
wants to know. Everyone has to wait his turn.) The first president of Normal
College, Thomas Hunter, finally retired in September 1906. In the same
interview she remembered his words from a speech he gave to an assembly there.
That's another reason I distrust the 1907 enrollment date. In April 1914, the
NY State legislature authorized changing the name of Normal College to Hunter
College of The City of New York.
According to her obituary in the New York Times,
Mrs. Hamburger was at that time the youngest graduate in the college's history.
She was too young to obtain a teacher's license, so she accompanied her father
and uncle to Germany. There she went to her first horse race (according to one
news article, and contrary to another) and became hooked
on playing the horses. Back in the US, she attended every Preakness Stakes
from 1915 to 1988, or only 73 between 1915 and 1992, depending on which news
report you want to believe. (Well, okay, the facts don't really depend on your
beliefs. You can believe one story or the other, if you trust one of
the reports. An obviously error-riddled transcript of a brief Bloomberg
broadcast claims she attended every Preakness from 1918-1988, which could of
course be true.)
Even after she became the first woman licensed in Baltimore to sell real estate
(at age 47, in 1938), she still managed her schedule so she
could make it to the track (Pimlico) almost every day. In 1975 she moved to
New York to be near her adult children, and gave up selling real estate to
become a rental agent for a Manhattan building, but eventually returned to
selling real estate. She became a regular at Aqueduct (she also went to
Belmont). She liked
her work apparently only a bit less than her hobby; she finally retired in
1990. ``The market had been absurdly bad,'' was her comment on real estate,
reported from her 100th birthday celebration at the end of that year, ``I miss
it -- life is without a challenge.'' She focused on the track.
(Incidentally, Rose Hamburger's 100th birthday celebration was organized by her
daughter Nancy Sureck. Mrs. Sureck is the founder of Centennial Celebrations,
and has organized them for such institutions as the Statue of Liberty, the
Metropolitan Opera and Carnegie Hall.)
She began to get a lot of attention after she
turned 100. As part of the centennial celebration, Nancy arranged for a
congratulatory letter from the Hunter College president. After that, she was
the guest of honor at several college functions. A letter she wrote to the
Daily Racing Form led to a wave of publicity when she was 100. Aqueduct held a
race in her honor on December 28, 1992 -- the ``Happy 102d Rose'' purse, which
she went to the winner's circle to present.
She came out of retirement to be a racing handicapper (``Gambling Rose'') for
the New York Post, beginning work on her 105th birthday, and she later
appeared on ``Late Night With David Letterman'' and other television programs.
She died the following August.
(In those days, the New York Post was also looking pretty terminal.)

- hurricane
- A extreme low-pressure (i.e., ``warm'') air mass whose structure is a
single convection cell with a calm central ``eye.'' The ones that approach
the east coast of North America form as tropical depressions in the
mid-Atlantic, typically drifting first west across the Atlantic and then
northward. (``Depression'' refers to the pressure.) They are typically
categorized on a five-point
Saffir-Simpson scale. In contrast to tornadoes, which last minutes and
wreak destruction along a narrow path (funnel diameter at the ground on a
scale as small as a hundred feet), hurricanes cause damage over a swath
tens of miles (~ tens of kilometers) wide, and create heavy showers across
a couple of thousand miles of seacoast. You can figure out a bit more about
how hurricanes work by reading the entry on Buys Ballot's Law.
For a long time, hurricanes were given women's names (on the basis of a
scrap of Shakespeare that I forget), but in the seventies it was discovered
that this was sexist, and since then men's and women's names have alternated.
Each successive tropical depression gets a name beginning with the next
letter of the alphabet, and a typical hurricane season has half a dozen
hurricanes. More on hurricane naming at the WMO
entry.
- husfriend
- A semantic and orthographic blend of husband and boyfriend.
I guess boyband might've been less clear. It's not a very common word.
Just now I had ``about 17,000'' ghits for hemidemisemiquaver and only
``about 494'' ghits for husfriend. Who knows? Maybe I'm misspelling
it.
When I showed Mary the glossary entry for
namorido (an equivalent but much more common
Portuguese term), the best English translation she could come up with was
``rentee.'' The word she had in mind, of course, was Leo. Her
nonce word for tenant points up an
interesting problem with the word renter, which is that it refers both
to the person who rents, and to the person who rents: lessor and lessee.
Famous husfriends include Kurt Russell (husfriend of Goldie Hawn),
Steadman Graham (Oprah Winfrey) and Tim Robbins (Susan Sarandon). I've seen
the complementary term gwife (for Goldie, Oprah, etc.). The word, or at
least the five-letter string, appears to be common. However, it seems to be
some kind of Welsh variable name (also gWife), and anyway someday it will be
short for Google Wife.

- Hot-Water Oil heating. That is, home heating by radiators, which in turn
are heated by hot water, which in turn is heated by oil. Part of an
abbreviation system that was in use in the Toronto area in the early 1980's.
I have no idea how widely this system was used, but with the exception of two
abbreviations (FAE and FAG, attested mostly in Ontario) it seems to be quite
obsolete today. So what better reason do we need to explain the system here?
The abbreviations were three letters long. The first two letters were FA, GA,
and HW, for forced air, gravity air, and hot water, respectively. ``Gravity
air heating'' is convective heating. The third letter was G, E, or O, for
natural gas, electric, or oil, respectively.

explained:
``In order to steer the boat, you must be going faster than the river.''
In Casablanca, Claude Rains (as
Captain Louis Renault) asks Bogie (playing Rick Blaine) why he came to
Casablanca.
Blaine: ``My health ... I came to Casablanca for the waters.''
Renault: ``Waters? What waters? We are in the desert.''
Blaine: ``I was misinformed.''
Find equally useful intertextuality at the positive buoyancy entry. Actually,
Casablanca is on the Atlantic coast. Also, the statement about relative
velocities is poorly phrased. It is just that if your speed relative to the
current is less than the speed of the current, then there are directions you
can't go.

- HYLE
- International Journal for Philosophy of
Chemistry. ISSN 1433-5158.
The ancient Greek word hylê
originally meant `woodland' and `[cut down] wood.' Even Homer used it in an
extended sense to refer to the material or stuff
out of which an object was made. Aristotle was apparently the first
philosopher to recruit the word to mean `matter' in a more general sense.
It may be that at some point, the journal name HYLE was a
backronym -- that is, they may have cooked up an
expansion to coincide with the word. That's the only excuse I can think of for
the fact that they always write the title in all-caps, but I haven't
encountered any such expansion.
You can read the journal online for free, or you can pay money and receive a
paper copy.
According to their
statistics, since 1999 their website has had about 1000 visits a month.
Since 1999, the website you're visiting now has looked just as unsexy as it
does now and has had about 500 visits a day. They should consider adding some
llama humor. And canned beans.
(Time flies when you're having fun. During 2005, the HYLE website had between
10,000 and 20,000 visitors per month. I haven't been preserving a systematic
record of SBF traffic, but 3000 daily visits was typical for 2006, so they're
clearly gaining on us.)
- hypermail
- A tool for managing mailing list

- hypernucleus
- A nucleus containing at least one hyperon
in addition to an ordinary nucleon. No hypernucleus is known to be or expected
to be stable.
- hyperon
- Any baryon that is not a nucleon. The only nucleons are the proton and the
neutron, and all other baryons are more massive (yeah, we say ``heavier'') and
unstable. (The free neutron is also unstable, but it's stable in stable
nuclei.) So hyperons are all baryons heavier than the neutron, and all
hyperons are unstable.
To review: fundamental particles that contain quarks are hadrons, and hadrons
are of two types: mesons, which consist of quark-antiquark pairs, and baryons,
which consist of three quarks. (Particles consisting of three antiquarks may
be called antibaryons, since they're the antiparticles of baryons, or they
may be called baryons, because one doesn't want to complicate the discussion
of baryons with the sometimes extraneous distinction between particles and
antiparticles.) Anyway, the only baryons one can make with only up and down
quarks are the nucleons, so the hyperons are baryons with at least one quark
other than these. Hence, one speaks of strange hyperons, which include a
strange quark.

- hyponym
- In taxonomy, a name invalidated by inadequate description. In linguistics,
a word whose meaning implies another inequivalent term, as scarlet implies red
(but red does not imply scarlet, so the terms are not equivalent). Hyponymy is
a kind of containment or partial ordering relation in semantics.
- HYP
- Harvard, Yale, Princeton.
- hyphen
- The remarkable text in the block quote below is taken from the third
edition of Watts' Dictionary of Chemistry (London: Longmans, Green and
Co., 1893). Henry Watts, B.A., F.R.S., died in the saddle, 63 pages into a
work of about 3000, and the third edition was completed by M. M. Pattison Muir
and H. Forester Morley (with help from an army of contributors). The two
editors dealt with the inorganic and organic chemistry portions of the work,
respectively. In his introduction, Morley necessarily dwelt on nomenclature
issues. One paragraph reads thus:
Hyphens
Hyphens are placed between each significant part of a name; absence of
the hyphen usually indicates close connection between two groups of atoms:
e.g., phenylethyl-urea is
C6H5.C2H4.NH.CO.NH2
while phenyl-ethyl-urea is
C6H5NH.CO.NHC2H5.
In the current IUPAC nomenclature, these
are N-(2-phenylethyl)-urea
and N-(2-ethylphenyl)-urea. Some things do improve.

- HYPS
- Harvard, Yale, Princeton, Stanford. Not a consortium, but a term used by
high-school guidance counselors.
- hysteron proteron
- A figure of speech, or perhaps better said a class of figures of speech:
any expression involving reversal of expected order. (The head term is Ancient
Greek for `later earlier.' That is, the cart before the horse.) Spoonerisms
and some syntax errors used to be considered part of this class of figures, but
as well many grammatical and even logical expressions. Now hysteron
proteron refers primarily to the interchange of two words in a sentence or
two phrases in a construction.
The classical example of hysteron proteron is Virgil's moriamur et in
media arma ruamus, `let us die and charge into the thick of the fight'
(Aeneid bk. ii., l. 358). The unnatural order is here supposed to lend
emphasis, but maybe it just helps the line scan. The English expressions
``head over heels'' (meaning ``heels over head'') and ``have your cake and eat
it too'' (meaning ``eat your cake and still have it'') are examples frozen by
convention. In French and Spanish one has main d'œuvre [main
d'oeuvre if the special character doesn't appear in your browser window]
and mano de obra, respectively. These literally mean something like
`hand of work' and really mean something like `manpower,' in other words `work
of hands.'
In The Merry Wives of Windsor, ``All his successors (gone before
him) hath done't: and all his ancestors (that come after him) may.''
I.A. Richards (q.v.) was a
hysteron proteron repeat offender; he made a habit of presenting various
claims about subjects before stating what the subjects were. Languages like
Japanese and Classical Latin, in which the verb in a
simple sentence normally follows not only the subject but the object and most
other sentence elements, can seem like prodigies of hysteron proteron
to an English-speaker. I keep repeating the phrase hysteron proteron
instead of using, say, a demonstrative pronoun for the term hysteron
proteron, in an effort to assure that if you do remember the term
hysteron proteron, you won't misremember the second word as the name of
a common subatomic particle.
- hysteron proteron
- A logical fallacy: assuming as true, and using as a premise in argument, a
proposition yet to be proved. This fallacy is obviously closely related to
petitio principii, the original sense of `begging the question.'
- HYTELNET
- HYpertext browser for TELNET-accessible
sites. Also available in Spanish.
- Hyvää syntymäpäivää
- Finnish: `happy birthday!' English: `I can't stop gnawing my tongue!'
Vowel harmony only gets you so much.
- Hz
- HertZ. One inverse second. The SI unit of
frequency. Usually implies circular frequency rather than angular frequency.
When I was a kid people resented the intrusion of this new name for what
everyone had always called cycles per second (cps),
but it caught on. According to current SI rules, when the unit is spelled out
rather than abbreviated the name is in lower case: hertz.
Herz is the modern German word meaning `heart.' Hertz is an
older spelling of the same word, still common as a surname and a rental car
company. The person honored by the SI unit is Heinrich
Rudolph Hertz. He was the first person to succeed in generating and
detecting the electromagnetic waves predicted by the electromagnetic theory of
James Clerk Maxwell. In the process of doing this work, he observed that his
detector was more sensitive to electromagnetic waves if it was exposed to
UV light. This was the first observation of what is now called the
photoelectric effect.
- HZ
- Historische Zeitschrift. A German journal that might have been
named `Historical Journal' in English. See Stuart Jenks's
page of Tables of Contents of Historical Journals and Monographic Series in
German for a complete table of contents (deutsche Seite:
Zeitschriftenfreihandmagazin Inhaltsverzeichnisse
geschichtswissenschaftlicher Zeitschriften in deutscher Sprache).
- HZ
- Short for HanZi. A 7-bit data format for arbitrarily mixed
ASCII and Chinese characters encoded in
GuoBiao. The point of using seven bits instead of
the standard eight is that this encodes within the printable-character
part of ASCII codes, making email transmission possible. This is the same
thing that's achieved by BinHex on Macintosh and Uuencode on
Unix. See RFC
1843
of 9/95.
- H1
- The civilian version of the Humvee. The
vehicle that first bore Hummer as its official
name. As of Summer 2002, it went for about $112,000.
- H1
- First Half.
- H2
- Second Half.
- H2
- A version of the Chevy Suburban (1/2-ton and 3/4-ton trucks) with a body
resembling the H1, manufactured by AM General and marketed as another Hummer model. As of roll-out in July 2002, it cost
a mere $48,800 stripped, $55,000 loaded.
- H2SO4
- Hydrogen sulphate, ``vitriol.'' Dissolved in water,
it dissociates and forms sulfuric acid. Also an oxidant.
- H3P
- Phosphine. [Pron. /fasfi:n/.]
- H8
- A common abbreviation of Shakespeare's play The Life of Henry the
Eighth.
