Not only did I not intend it, but I don't know what you're talking
about.  Am I losing my mind, is my server going haywire?  I'm missing
Harter's jokes, and reading responses everywhere to stuff I never even
dreamed, at least not memorably.  How about just explaining what
"intent" is.  Is it just whatever one has in mind prior to sitting down
to write?  Or is it whatever of that ends up getting written?  Or is it
anything that consciously comes to mind before and/or while writing? 
Or can it include later consciousness of what one's done?  Or what? 
And how trustworthy should we take authors to be on whichever of these
it is?  In a nearby thread, in rec.arts.books, called "philosophy,"
Richard Harter suggested that one might write a story with a particular
theme.  I took this idea, and sat down to write a story.  I wanted it
to be a story - to pick just one point - about a philosopher talking to
his mother about her housekeeping and ridiculing her for it and about
her meekly accepting this ridicule.  The reader, meanwhile, would be
aware that the ridicule could equally apply to the philospher.  But
when I'd written the thing I noticed that the mother came out with a
remark returning the ridicule to the son.  What's more, she seemed to
know more than most readers would on a first reading.  Now, what's the
authorial intention on this point?  And, who's the author?  I mean, it
could be Harter, couldn't it?

This is a very common attitude.  In addition, it used to be very expensive
to store data.  Shaving 2 characters off a piece of data which occurs
often was an easy trade-off to make....back in 1970.  I plan to have 3
months worth of cash on hand, not make any airplane flights, and identify
the other things that may make life miserable due to bad data,
programming, etc.  Unfortunately, I can't do a damn thing about income
taxes; my assumption is that if I get affected, everyone else will, too.

In the current "debates" (as they're generously called) there are the
following two sides.  One dismisses anything new as "gibberish."  The
other attempts to appreciate anything new, and see whether it looks
like a good new way to start talking or not.  Those of us in this
second group sometimes like to say that WHENEVER anything new comes
along, the footdraggers will scream "gibberish!"  But is this so? 
What's the history of this phenomenon?  And what would explain its
newness, should we find that it is new?  Is it possible that Heidegger,
to take the most obvious example, thought in a more radically new way
than had other thinkers since Plato?  (It is documented that Socrates
was accused of gibbering.)  Or is it possible that he could have taken
the time to write more clearly?  Is it possible that some pomo writers
present us with both new ideas and unneccessary obscurantism (I think
of Foucault here, but hesitate because most people will quite wrongly
think of Derrida)?
My question is not whether the "Gibberish!" party is right.  My firm
opinion is that they're a bunch of anti-intellectual clods.  But I want
to know whether or not they have forerunners in other eras, and if not,
why not.
Yes, the stuff quoted up at the top is recognized as sarcasm.

So let's just have the spatiotemporal discontinuities differ
NUMERICALLY as well, and we're set, no?  I mean, as long as the

 "school" is kind of vague.  
 I put top priority on code that can be related to real experiments which 
 are done in class or by the students.  I will give an example at the end. 
 Failure to connect the 'theory' of physics classes to the real world is 
 a major problem -- identified in the Feynman story about his experience 
 in Brazil but there is nothing unique about that sort of problem -- and 
 needs to be addressed at all levels. 
 At the middle school level, it is hard to do better than the CD-ROM 
 based on the book "The Way Things Work".  Even a PhD who knows all 
 about gear ratios may not know how a gearbox works.  The mammoth stuff 
 is a little silly for adults, but the content is excellent. 
 There is a set of programs called CUPS developed for PCs (turbo pascal 
 with a decent interface, developed with an NSF grant based at Maryland) 
 that is available in conjunction with some workbooks.  I have not used 
 (or even seen) the books, but some of the programs work really well. 
 I especially like the electrostatics calculations since it models 
 something easily done in lab/lecture.  They are of varying sophistication 
 with some scattering problems out of nuclear physics, relativity examples, 
 and simple mechanics demos.  They are targeted at upper division 
 undergraduate for the most case, although some are useful as numerical 
 demos at the grad level. 
 Finally, there is a growing collection of JAVA applets, some very 
 sophisticated.  We used some in our Saturday Morning Physics program 
 last weekend with a lot of success.  I have a page with links to some 
 of them as well as the index pages at Gamelan and TIPTOP (and some of 
 sites ranging from the sublime to the ridiculous that we also used) 
 at 
      http://www.scri.fsu.edu/~jac/smp-sites.html
                                                  for your browsing 
 pleasure.  I have not got around to annotating it with the ones that 
 we actually used.  I found the optics one from Taiwan to be the best 
 way get a sense of ray tracing I have ever seen.  There is a really 
 nice one for the Schroedinger wave equation with time dependence 
 and different well choices.  
 One that worked exceptionally well was the cannon from Oregon.  We 
 have a spring launcher that is very well calibrated and reproducible. 
 We set it at 45 degrees at full power and launched a ball toward a 
 small (10x20 cm) box target (foam inside so ball will not bounce out)
 about 6 or 7 meters away.  [The distance of about 20' matched the 
 20 units between cannon and target in the JAVA applet really well.] 
 At this setting, it went over the target by about a meter.  We repeated 
 it with my partner catching the ball at about that height over the box. 
 Then he fired up the applet and, with student suggestions, altered the 
 firing speed at 45 degrees until the shot went over the simulated 
 target by the same amount (about 3 units).  OK, now we have a working 
 model of our gun-target system.  THEN, again with student help, we 
 adjust the angle of the model cannon until the target is destroyed. 
 Then we set the launcher to that angle, shoot, and the ball plops 
 nicely into the box.  At a 60 degree launch angle, this is quite 
 impressive since it goes almost to the ceiling of the lecture hall. 
 Experiment --> model --> solve new problem --> test answer.

 The National Academy of Sciences sponsors a study periodically on the 
 ranking of physics departments that are classified as graduate research 
 doctoral institutions.  You would have to buy the book to get all the 
 details, but the requirement is for a threshold number of PhDs on the 
 order of 1/year over the 5-year reporting period.  The report includes 
 some objective measures, but the ranking was based on purely subjective 
 evaluation of the quality of the research and the effectiveness of the 
 graduate education.  The list I have is ordered by research quality, 
 that is, a measure of past reputation of the faculty and their work. 
 They are: Harvard, Princeton, MIT, UC Berkeley, Cal Tech, Cornell, Chicago, 
 Illinois (at U-C), Stanford, UC Santa Barbara; Texas (at Austin), Columbia, 
 Yale, Washington, UCLA, UCSD, Penn, Maryland, Michigan, Rutgers. 
 I do not think USNews ranked physics, or if there are objective ranks. 
 For example, based on citations/faculty, UCSB should be #1.

 An amusing thought.  Who do we trade with?  The American Institute of 
 Physics (aip.org) has lots of statistics but does not do rankings AFAIK.

That reminds me--one of the runners in the Olympics (it may have been

 The original question was just an example of vector addition, but, as 
 noted in this reply, aircraft do compensate for cross winds.
 If you want some data, contact your favorite airline for their flight 
 schedule and compare the E-W and W-E flying times for non-stop 
 transcontinental or transoceanic routes.  After correcting for time 
 zones, you will see dramatic differences due to the jet stream. 
 Since the jet stream moves day-to-day and seasonally, there are some 
 fudge factors built in.  I have had ATL-SFO flights arrive almost an 
 hour earlier than scheduled when the jet stream location and the 
 available flight corridors were favorable.

But the probability that he will respond to my arguments is probably
no greater than the probability that the religious authorities will

The two are the same phenomenon, so if you know what causes

Going back to the original question, a relative angle causes geometers

No, but it does imply that he has doubt about the message received, and
thus an implicit recognition that the same text/words can convey multiple
messages (substitute the word "meaning" if you prefer) -- and thus
that there is a functional and logical difference between the words
and the intended message.

The message is what is received in the mind of the hearer.  The words
uttered are, well, the words uttered.  See above.
If you want an example -- I could say "So-and-so is a bastard" with
intent to convey merely that his/her parent's weren't married at the

Right.  Isn't it ironic that from this (self-evident) claim,
deconstructionists seem to jump to the conclusion that the text is
primary over the inferred intent, and that any interpretation that can
be screwed out of the text is valid -- and equally valid with any other

So the common usage of terms such as "amorphous solid" in published

You clearly care about this stuff more than I do.  Arguing semantics with

Care to offer an opinion on "liquid crystal"?
Unfortunely I am nowhere near a science or engineering library right now,
so I don't have access to all the books on amorphous solids that I used
back when I was active in publishing research in this area.  So to obtain 
a definition of solid, I only have my old undergraduate solid state text
book to refer to:
 "Elementary Solid State Physics" - M. Ali Omar p. 2: "The atoms in some
solids appear to be randomly arranged, i.e., the crystalline structure is
absent.  Such noncrystalline - or amorphous - solids will also be
described briefly."
This reference is quite typical of what I remember a large number of books
saying.  In essence, most of what we know and can easily explain about
solids has to do with crystalline properties (Bloch states etc).
Amorphous solids are less understood, harder to understand, and considered
an advanced topic.  Like it or not though, any rigorous definition of
solid I've ever seen refers to viscosity, not molecular order.  Glass
passes the test at hundreds of degrees, let alone room temperature. 
The point someone else made about the prestigeous Journal of
Non-Crystalline Solids is another good example of how the word solid is
actually used by scientists who work in this area.  Incidently, there are
a lot of papers, in fact conference proceedings, on glass in this journal.
A simple test of what is the usage of the word among scientists: go to
your favorite index (INSPEC, Current Contents, Uncover, Physics Abstracts
..), look up "glass" or "amorphous", and see how many papers appear in
solid state journals compared with liquid of general physics journals.
As far as I can recal the discussions here, the opinion of everyone who
has indicated that they have published in the area of amorphous materials
has been that the usage of the word solid in technical writing includes
amorphous materials.  Perhaps you gave your qualifications for disputing
this before I entered the thread.
> I bet you think that quarks really do have color and
> charm, too.
Now what did I say I would do to people practising bifurcation and/or
straw man argumentation?  Oh yeah, I don't make threats!
Actually, this is a particularly bad illustration of your point.  No
physicist believes quarks to have color in the sense of interaction with
your eye to appear red - but the usage of the word in the quark context
would probably lead many physicists to say that color is a homonym.  You
are arguing as though I had said something like a "solid campaign
platform" must have a certain viscosity.  The boundaries of the definition
of solid are what we are talking about, not alternate meanings.  Now I see
why you put the smiley face after accusing me of sophistry.

Yes; in general relativity, more eccentric, smaller orbits have greater
perihelion precession.  In Autodynamics, supposedly, precession is
independent of eccentricity; it only depends on the Sun's mass and the
"orbital radius."  Whether or not the orbits are assumed to be circular or
whether or not "orbital radius" is another name for semimajor axis is
questionable.

The problem is that, supposedly (I keep saying supposedly since I have as
yet seen no derivation) in Autodynamics there is a proportionality law
(which was posted) relating the perihelion precession of a planet to the
"orbital radius" of a planet.  However, the constant of proprtionality
apparently is not calculable but instead must be gotten empirically.  In
other words, given that Mercury's perihelion precession is 43 arcsec/100 y,
they can then find their constant of proportionality is and tell you what
the predicted precessions are for Venus, Earth, and so on.
However, general relativity can tell you Mercury's perihelion precession
_from first principles_.  You don't need to plug in the perihelion
precession for another planet to "calibrate" the equation; general
relativity just tells you what it is (and what it is for the other
planets).
Furthermore, Autodynamics' supposed predictions of the perihelion
precession rates for the other planets are so high that I should think that
these would have been observed by now.  Have there been any dedicated
efforts to measuring the precession rates for non-Mercury planets?
> I make high school students show their work.
I guess they didn't learn that in the Autodynamics school.  (Amusingly
enough, there answers aren't even write.)

   That's right, Lew -- I made it out of whole cloth, merely to annoy you.
Looks like  it worked.  But you can rest easy -- Newton never studied
religion, and even if he did, he wasn't paying much attention at the time. 
And he certainly wasn't influenced by anything he didn't notice when he 
wasn't studying.
Cajori says:

   Uh-huh.  So Cajori is correcting an idea that I invented.  Glad to see
he's reading my posts.  But you may have something interesting to
contribute.  It's possible that all the attacks on Newton were actually
misdirected -- what have you read?

   Right; that's from the first edition of the _Opticks_.  And as I've said
no more than four separate times, at the max, it's true that Newton was,
especially at that time, committed to the philosophy of mechanism --
which did nothing to prevent him from holding other views, as well.  As
I shouldn't have to point out, introducing the notion of gravitas in  the
_Principia_ would be enough, by itself, to commit him to action-at-a-
distance, even in the absence of any other considerations, since it's a
force that exerts itself  across space without any mechanism to account
for its workings.  As his contemporaries didn't hesitate to object.

Let's look at this from a subjectivist perspective. If someone says
something new you either understand what he's talking about, being
sufficiently privy to his conceptual framework or you don't. If you don't
understand the person, his statements will sound like gibberish even if it
is a profound new revelation. Then we've got all sorts of options such as
asking for an explanation, acknowledging one's own deficiency on the
subject, assuming the complexity is over one's head, engage the person in
an illuminating conversation, maintaining noble silence lest we reveal our
stupidity or ignorance, try to fathom the other's frame of reference, or
even try to learn and perceive something new. Those options are of course
only open to us if we have a fair amount of self-reflective capacity and
_want_ to understand the other person. However most often that doesn't
seem to be the case and the preferred course of action is to denigrate the
other's statement as gibberish, or even attack them personally, their
"gibberish" being considered an affront to one's own intelligence. In
other words the objective is no longer (if ever it was) to express, learn
or understand, but rather to triumph over an "adversary". On Usenat that
seems to be something akin to standard procedure. Then again, I just can't
help but get the impression that much of the stuff really IS just
gibberish. But who knows, maybe I'm just revealing my own ignorance.

"calculus" and things like "airplanes" and "microwaves" is not all that
intimate; it's just a foundational item for later technology.
With a similar strength of foundational connection, for the want of
special relativity, QED would be lost, for the want of QED, lasers and
transistors would be lost, for the want of lasers and transistors, the
internet (and usenet) would be lost, for the want of the internet, the
original question would be lost. 
Thus I find the question somewhat ironic.
Mind you, GPS is a good example.  Just doesn't adequately illustrate how
pervasive the butterfly effect on technology from relativity, IMHO.

I'm fairly sure that was a ramjet, rather than a scramjet (i.e. the

the flow or burnt.)

Subject: ? group theory and classical mechanics?
From: cbloom@mail.utexas.edu (Charles Bloom)
Date: 14 Nov 1996 17:13:44 GMT
Having just learned some group theory, I am impressed
by the derivation of degeneracies and quantizations using
only group-theoretical arguments.  However, it seems to
me that the same methods should be applicable to classical
mechanics.  i.e. in quantum we have :
dx/dt =  [x,H]
dp/dt = -[p,H]
as our laws of motion; while in classical we have:
dx/dt =  (d/dp)H
dp/pt = -(d/dx)H
these seem very similar as far as invariance-of-H under
symmetry groups go.  In fact, if you take H as the classical
electron orbit problem (or the gravitational orbit, if you
prefer) then you will have the same 3-D rotation group as in
the archetypal quantum problem, which would imply spherical
harmonics and quantized motion.
Where is the mathematical difference that makes this reasoning
wrong?

On September 30, 1996, the California Department of Transportation has
completed its transition to the metric system.  As all plans for new
highways are now drawn in metric units, it only makes sense to give
metric distances on road signs.  You'll probably see soon many more
metric road signs, not only in California, as most other departments of
transportations have already converted, too.  The U.S. government is
clearly going metric.

No, it's the universe itself which hands out the prizes. General

From: patd20@aol.com

gravity is not a force, or at least if it is I've heard it often described
as a fictitious one. It is more accurate to describe gravity as a quality
or property of matter- with direct proportionality between density/mass,
and gravitational warpage of spacetime. By density I mean that as objects
are denser, the local region is more affected (i.e. black
hole/singularity, galactic cores, the sun).
gravity- a manifestation of the tendency for mass to warp the space around
it causing an illusion of attraction.

Maybe a hundredweight is always the same (what about wet silk?), but
if you are putting your weight from a freighter (measuring your silk
in some big unit, for instance 1.5 standard freighter fillings), put
it on several lorries (each carrying several hundredweights), selling
it by the ounce (the special dry american silk ounce of course) and
use it by the grain, a lot of people have to do a lot of odd
calculations.
With the SI-System you do nothing but shifting the decimal point or
do an occasional change of the prefix.

Of course, but when I fill something from the stovetop pot into
the fridge pot I don't want to calculate stovetop-hogsheads into
fridgepot-hogsheads, just because they are made with different materials
or from different companies.

Depends on the dough and on the size of the holes in the basket.

There is no difference. A container has some volume, because
it takes space (in a freighter). Whatever is in the container
has a volume, because it fills all space in the container.
And the freighter itself has several volumes, according what you
want to measure.
It is impractical to measure the "capacity" of a container in one
set of units but measuring the "volume" of the things you want to put
into
the container in a completely different set of units.

No problem. Call your container a con.
Define:
	One con is the inner volume of the international con-prototype
	in Hinterschlumpfsdorf. The inner volume of the international 
	con-prototype forms a perfect cube in the geometrical (euklidean)
	sense. One con of platinum forms the mass-prototype. The third
	root of a con forms the length prototype.
	So lengths are measures in con^(1/3). Use the time
	it takes the platinum prototype to fall from the clock tower
	of Hinterschlumpfsdorf to its base (in vacuum) as the basic time
	unit.
	Then define your prefixes as powers of 10 and you've got a unit
	system that is almost as good as the SI one.

You are talking about medieval farmers, and predeccors of the SI-System.
I don't want the US to change to the earliest unit system that uses the
meter,
and I don't want it to change to some old cgs-System. We are talking
about
the SI-System.

A liter doesn't have mass. You measure volume in liters.

Funny thing about the obvious: it's often wrong.
1. Propellants are the cheapest single item in launching
   anything to orbit. Liquid oxygen in bulk is cheaper 
   than beer. Development costs, capital, handling,
   everything else is more expensive. Spending billions to
   make the cheapest component cheaper still is senseless,
   unless the goal is to run a welfare program for aerospace 
   industry managers and engineers. To build a commercially
   successful launch system instead of a research vehicle or
   a curiosity, one must focus on (a) economy, (b) economy, 
   and (c) economy. Not performance.
2. One gets useful thrust from any variety of jet engine
   by throwing the combustion products out the back end faster
   than they entered at the front. When the incoming air is
   moving more than Mach 4 or so it's extremely difficult to
   heat it enough during the short time it's inside your
   engine so that it leaves at a noticeably higher speed.
   And when screaming along at Mach 4 you have a whopping 3%
   of the energy required for orbit, so you still need
   rockets for the other 97%.
3. Tearing along at Mach 4 you'd better be above 99% of the
   atmosphere lest you become a meteor. Precious little 
   oxidizer available up there.
