  Geez, it does not take long in this newsgroup for the so-called
experts to " shoot oneself in the foot".
  I can see that Matt wants to get the facts straight and clear.
  But I do not know what this   support@forecasts.com  is here for, but
they sure shoot themselves in the foot.
  And the point I want to make with this post is that one of the major
reasons I no longer accept email is because there are thousands of
these so-called experts using the Net and the Web to get at you via
email with their drab, inaccurate sales pitches. Sure it takes but a
second to determine whether a email is a baloney sales pitch but when
you have hundreds of these sales pitches daily the time adds up , not
to mention the *irritation factor*.
  So I just turned off my email account -- it is not worth it in a
climate of free email. At least with postage mail there is the cost to
the sales pitchers of their time and their postage fees.
  I bet anyone who is a regular to misc.invest.stocks will be inundated
with these sales pitches baloney. And I no longer see any of them , ha

How is this different from "underlying assumptions," a phrase
known and understood by everyone from businessfolk to engineers
to musicians?  I am trying to understand why this specialized
terminology has been introduced.  From the subsequent
explanation, it does not seem as if the terminology -- center,
play, etc. -- provides any more rigor than existing and
well-understood terms.
So now we know what Derrida (should have) said: "The Einstein
constant is not an underlying assumption (of physics)."  (I'm
assuming that the context of his comment makes physics the domain
-- er, "game" -- of concern.)  But as with many of Derrida's
passages, once one understands what he is trying to say, two
responses immediately beckon:
  (1) Like, DUH.  
  (2) What is the purpose of the specialized terminology (and 
      elsewhere, of the painfully convoluted prose)?

This all makes perfect sense, *especially* if one replaces the

Translation: once one has a theory of an ur-myth, any actual
myth that doesn't fit the theory poses a challenge to the theory.
(Note the translation is shorter and more clear.  What purpose 
does Silke's terminology serve??)

In other words, they think Propp's theory is poppycock.  
-*--------
There are a variety of reasons for introducing specialized 
terminology.  Some of the good things it achieves are:
  CONCISENESS
    Mathematicians could just say "Assume S is a set with a
    binary, closed, associative operation + that has an identity
    and inverse."  But this gets long to type and tricky to read
    time after time after time, so we define the term "group"
    to mean just this kind of thing, and now when I say 
    "group," Siemon knows exactly what I mean.
  NAMING NEW THINGS
    How else will we refer to that new species, if it doesn't
    have a name?  (This, of course, is a special case of the first,
    since we could always identify a new thing through a definite
    description.)
  CLARITY
    Attaching a name to a commonly used description or set of
    assumptions in a field is a good way to demarcate their 
    ubiquity and provide useful context to one's readers.
But terminology has a cost, and often its bad results are greater
than its good:
  OBSCURITY
    If physicians use Latin abbreviations, patients cannot read
    prescriptions themselves.
  HABIT
    Careless writers become accustomed to creating terminology, 
    and they create far more than is useful.
  TERMINOLOGY ENVY
    "Those folks in the technical fields have all the fun!"
Once upon a time (this is my myth of the academic good old days)
English teachers studied the how and why of terminology.  Perhaps
Silke can explain to me why literary theory needs the term
"center" in this odd sense?  From her example so far, this term
makes it more difficult to say what is more easily and clearly 
said without it.

     Quite.  The term isn't part of Derrida's lexicon -- Hyppolite
used it the question Derrida was replying to, and Derrida quickly
switched it to "center."  (What Hyppolite meant is unclear.  We can
speculate about it, but we can't ask him, since he's been dead low
these many years.)

Well, now it's my turn to question your analogy.  You were talking about
DELIBERATELY PRODUCED gibberish (which is what you claim Derrida utters). 
But your example is of a madman, who has no idea that what he is producing
is gibberish, and certainly isn't trying to "trick" his audience by
"disguising" it as sense.

Fair enough.  But remember that we are talking only about events whose

things.

You have an incredibly impoverished concept of meaning.  "Come here!";
"Yaba daba doo!"; and "What time is it?" are all meaningful utterances,
and none of them has any truth value at all.  To claim that only
utterances which are either true or false are meaningful is just silly. 
Now, you might want to say that Ramus (and Derrida) are PURPORTING to
utter propositions which make truth claims....You may want to, but you
can't, because if the utterances are purporting to do anything, they are
clearly not meaningless, by definition.

Note that you are not evaluating Collingwood's claim above, since you are
using words like "understand" and "express" in senses which are completely
different from those in which he uses them.  So, all you are saying is
"when I say understand, I don't mean what he means."  That's your right,
of course, but it constitutes neither evaluation nor argument.
But, leaving that aside for the moment, haven't you just disproven your
larger point?  You just as much as said that it is perfectly possible for
a snake oil salesman (say, Derrida, in your account) to actually be saying
meaningful stuff, despite himself.

Okay, look, this seems to me to be the crux of the matter.  I am not
claiming for a second that a speaker cannot bamboozle a hearer.  But, what
on earth leads you to believe that the speaker is uttering things which
are utterly devoid of meaning, rather than things which mean in misleading
ways?  Here's the question I want to ask:
How can something be intentionally made to appear meaningful, without
bearing any meaning?  Isn't meaning unavoidably generated by the
appearance of meaning?

The formula for the area of a circle is known to predate the discovery of
calculus by at least 3600 years.  It is very likely Imhotep, the man who
supervised the building of the pyramids, used the formula for the area of
a circle even earlier, say 3000 B.C.  The formula was probably handed down
to Imhotep by some eccentric mathematician who could not be trusted to
socialize with the pyramid workers.

As I said before, explanation ("why") is a rhetorical
process.  By the time of Kepler, we already have a
rhetoricization of planetary movement; it is an ellipse,
that is, a particular geometrical form which we have a good
bit of text about, and in addition Kepler observes that a
line drawn from one body to the other sweeps out an equal
area in equal time.  Probably from that time forward it
would not be possible to separate intuitive ideas of form,
shape, and movement, from the language which had begun to
be attached to these particular cases.  Could a person
_feel_ a planetary orbit?  I don't know.  Maybe if there
were athletic beings floating in space, they could catch 
planets as cleverly as my dog catches a thrown ball.
I don't see why the detailed mechanics of computation are 
so important to your understanding of understanding, but we
keep coming back to it ("explain").  Why can't people take
them on faith, since they seem to work?

  That was the Vietnam War and such silly putty ideas by US

  Likewise, silly putty idea that to think that the elliptic curves
allied with Axiom of Choice allied with p-adics would crack Fermat's
Last Theorem.
  The silly buzzards of mathematics do not yet realize that if in
mathematics you require these awfully long proofs means not that you
are so clever, but that your whole entire notion of what you are trying
to prove was a falsehood, a delusion, a Burk and Wills inland sea when
there was no inland sea. And the more monsterous of a mathematical
falsehood the more pages of abstruse , abstract and goofy ideas one has
to muster in order to convince other fellow birdbrain math people. They
say they are convinced not because they are convinced but because it is
so long and they do not understand it and others around them say they
are convinced, hence they give in, they cave in and say they beleive
it, yet they do not even understand it.
  How could anyone convince Newton or a Newton follower that "time
dilates" or "space contracts". Likewise, how in the world could I
convince Andy Wiles, Barry Mazur, John Conway, Ken Ribet that their
"Finite Integers" lacks precision. Lacks mathematical precision and
that the reason their FLT proof is so long, cumbersome, arcane and uses
every kitchen sink of mathematics, is because whenever you have a foggy
statement using foggy numbers, then you must build up this huge
delusional edifice.
  P-adic = Infinite Integer proof of FLT is easy. FLT is false because
counterexamples exist. You see, a P-adic proof of FLT requires one

Okay, I'm coming in very late to this discussion, and I have no interest
in reading up on what's gone before, so I have no clue what Einstein is
doing here.  However, if we leave him out for a moment, I can give a few
more general answers to Russell's question about the use of the term
"center" in Derrida.
1) Derrida is a post-structuralist.  This is often taken to mean that he
is a critic of structuralism (which he is), but it equally means that he
is building upon structuralism.  In one of his first papers (and the first
one to be given in the U.S.), "Structure, Sign, and Play in the Discourse
of the Human Sciences," Derrida basically deconstructs Levi-Strauss's
system, which is a structural analysis of myth.  "Center" is one of the
first terms he uses in this paper, for very specific reasons which I will
address in a moment.  The point of this paragraph is merely that he
introduced the term initially in a context which made a lot of sense. 
Whether it makes sense in the context you are currently discussing, I
can't judge, 'cause I don't know what it is.
2) So, why "center?"  Well, Derrida asserts that the concept of structure
(which Levi-Strauss relies upon) necessarily implies a center.  Without a
center, there is no structure, he says.  Why is this claim useful? 
Essentially, because Derrida decided that he wanted to develop a SPATIAL
METAPHOR.  As soon as he has asserted that all structures have a center,
he immediately further asserts that a structure has its center elsewhere. 
This, I would assert, is a useful rhetorical move: the effect is to
defamiliarize the concepts of structure and center, by positing a spatial
relationship between the two which is counter-intuitive.  Lacan had
already engaged in an extremely similar project, positing a "topology of
the subject" which suggested, for example, not only that that the self
exceeds the "I," but that the unconscious is located outside the self
("The unconscious is the discourse of the Other").  At base, then, the
choice of "center" is meant to allow a "topological" discussion of things
like meaning and subjectivity, one in which metaphors of space and
position are constantly deployed.

Well, here, Derrida is explicitly following the lead of his object text. 
You might say he is engaging in a bit of critical parasitism, taking L-S's
term and having a field day with it.

Derrida would emphasize that the center is the only thing which allows
there to be any "play" at all.  Without a center, there would be no
structure, no rules to play with, only chaos.  The claim, then, would be
not only that actual myths challenge the theory, but that without an
actual structure of some sort (which is the object Propp and Levi-Strauss
are trying to get a handle on) there could be no multiplicity designatable
by the term "myths."  I don't know if that answer's your question or
not...

Yes, but in this specific case (ie, Silke's last sentence compared to your
last sentence), it is clearly the case that Silke's description is more
useful than yours.  It provides important detail, which you lack, since
there are many different kinds of poppycock in the world.

You leave out something like "RESONANCE" or "TROPOLOGY."  The ability to
set up a whole system of terms, revolving around a central trope (in this
case, spatial metaphors), which is more than the sum of its parts. 
Obviously, "center" would be a superfluous term in the example we're
looking at, if it were the only term of its kind being used.  When
combined with other terms, they create a set of analogies which operate an
several levels at once.  On some levels, they make the argument more
intuitively graspable (hence, helping out conciseness and clarity), on
other levels, they are meant to function NON-intuitively, which is to say,
for rhetorical effect (which actually also renders Derrida's writing more
concise, since it requires fewer words to have the same effect).

Actually, this is an old Hindu story.  I am amazed at how many times it
gets recycled.  It also seems funny that, in the original story, the lecturer
was postulating that the fundamental "stuff" of creation was nothing, something
which some QM theorists believe.  I once had a quantum physicist tell me that
quarks (or the particles that make them up if any) were really "nothing, 
but that nothing is spinning."  I don't know if its science, but I like it.

     The paraphrase Silke offered you was "ground."  And I'm very
doubtful about your interpretation.  But let's press on.

     If you want to claim that's true for much of what Derrida has
to say, your job is to show it.  But you've got a back-log of such
comments to support, and you show no signs of getting to it, so I
won't expect you to do any better here.  With that out of the way,
let's look at Derrida's remark.  He doesn't claim to be making any
revolutionary comments about physics -- he's answering a question 
from Hyppolite about the paper which he just gave.  The question
asks him to relate certain of the ideas he presented to Hyppolite's
thoughts about relativity.  Most of Derrida's reply goes off in a
different direction -- it's plain that physics interests Hyppolite
more than Derrida.  But in the end Derrida makes a brief comment
about Einstein -- the one that's attracted so much attention. 
>   (2) What is the purpose of the specialized terminology (and

I'm no expert on this stuff, obviously, but let me note...
Richard Borcherds, writes "In spite of several 
statements to the contrary in the mathematical literature, the 
original proof of the no-ghost theorem by Goddard and Thorn is 
mathematically rigorous".  This is from his paper "Automorphic 
forms and Lie algebras", available at 
http://www.pmms.cam.ac.uk/Staff/R.E.Borcherds.html
And he had better be right, for his own sake, because he uses
this theorem in his proof of Conway and Norton's "monstrous 
moonshine conjectures" --- see "Monstrous moonshine and 
monstrous Lie superalgebras", also available above.  More precisely,
he uses it to construct some generalized Kac-Moody superalgebras;
he says that the idea of using the no-ghost theorem to prove 
results about Kac-Moody algebras goes back to Frenkel's paper, 
"Representations of Kac-Moody algebras and dual resonance
models", Lect. Appl. Math. 21, AMS (1985) pp. 325-353, and he
says this paper also contains a proof of the result.
Probably your point that these calculations are "formal" is 
understood and regarded as acceptable within this body of 
mathematics literature.  Work on vertex operator algebras typically 
uses formal power series to the hilt, and while an analytically
minded mathematical physicist might properly regard this with disdain, it
is perfectly rigorous as pure algebra, and the algebraists love it.
(In fact, it lets them do a lot of this stuff over an arbitrary field.)  
Of course, a theorem can be rigorous and still not properly understood!

  It should be pointed out that mathematics has never had a revolution
with its Number Theory. We have taken for granted that "finite" for
Finite Integers makes sense. And noone has asked the question can you
have a number that was completely, 100% finite? Or do all numbers need
a component, and ingredient of infinity in order to be born a full
fledged number. That is why I say "finite numbers" are merely a foggy
notion, a misconception that appears to work but in the world of
mathematics that begs of 100% precision, "finite" is fools gold or an
optical illusion, or a mirage.
  The Finite Integers were the 1993 "walking dead". It is only a matter
of time that physicists find a region of physics where P-adics are
necessary and essential and where finite integers simply do not work.
Once this is found, then mathematics will be henceforth forever changed
for the better. On that day, no longer will exist Finite Integers and
all Integers, all Counting Numbers will be Infinite Integers or
p-adics. We will still use finite integers for common everyday
discourse just as most of us use Newtonian Mechanics for rough
approximations. But when we want to do real, 100% truthful mathematics
we have to use the p-adics or Infinite Integers, just as we have to use
Quantum Mechanics and not Newtonian Mechanics when we want to do 100%
physics.
  That was quite a good movie THE WALKING DEAD. But I am partial to all
Vietnam movies and make a habit of watching all Vietnam Movies. The
complex social milieu of the Vietnam War is an excellent genre of
movies. The portrayal of individualism in the Western genre is another
artform. Anyone know where this movie THE WALKING DEAD was filmed,
looked like southern California with those palm trees?
  Keep the Vietnam movies a-coming. And please, film them in a real
jungle, not some California florist adaption. I think one of those
Vietnam movies -- 300 Spartans was filmed in Arizona even, (sic ? ) it
is a hard stretch of imagination to picture Vietnam as the flora of the

The always changing speed of the antenna do influence 
the received signal. The most prominent effect is a doppler 
shift of the signal. However, as the movement of the earth is well
known, these effects can be compensated for to a high precision. 
The astronomers looking for planets are measuring changes in the 
radial velocities of stars with a resolution of 5 m/s, very
much less than speed of earth. 
To detect the doppler shift in the CBR due to the 370 km/s speed 
of the solar system would be no match, if the signal was not so noisy.

A gyroscope can be used for stabilizing the instrument platform
to make it possible to aim the antenna. But it obviously cannot
cancel the changing speed of the plane. The plane obviously
has to follow earth in its movement, or it would became a 
spaceship or submarine.

Right. The surface of earth is under constantly changing acceleration.

I suppose the "instruments" in this case are microwave 
antennas. Are you saying they are not directional sensitive?
You can't be serious! You _do_ know that radio astronomers
are using the directional sensitivity of these antennas all
the time, do you not? You do know that you can lock such

I advise you to think a bit about your "relative standards" ... 
shiny Farriaris and similar vehicles in Geneva are hardly rare at 
all .... most either driven by those of old money, politicians, 
or pimps (the new standard there for the kids of the rich seems 
to be brand new Harleys ... which they ride poorly). In any case
mediocrity in physics is miles above those elite drivers ... if 
measured in intellegence.
Stick with the physics ... and a new Opel will serve your driving 
needs with a few dollars left over to have a weekend or two in

The "action" is the integral of a Lagrangian over a path.  In your case,
you've got something like the action for electromagnetism.

As far as I can tell, it means "guess".  Instead of saying "we've got
this big equation, so we guessed that f(x) was a solution and hey, it
worked!", scientists will say "using f(x) as an ansatz solution to the
equation..."  Or something like that.  It literally means "beginning" in
German, so maybe it's more closely used to mean a trial solution.

 Key concept: simple cases.  Did you visualize accurately what happens

 If you did not go any more deeply into mechanics than you did 
 without calculus, I can understand this viewpoint.  For example, 
 I doubt if you did anything with a driven damped non-linear 
 oscillator in your earlier study of mechanics.

 I don't think so, I think they have a bigger view of what Newtonian 
 mechanics consists of than you do.  That is, they use the words 
 "Newtonian mechanics" differently -- perhaps more like Newton 
 would have used them given that he invented the calculus and 
 related numerical tools in order to develop and use his mechanics.

 Or perhaps studied enough, to go beyond the superficial.  
 Certainly, in my experience, that is when I obtained a deeper 
 insight into what any particular subject is and how it is related 
 to other material.  As an example, I am currently reading Derrida's 
 Introduction to Geometry and some Autodynamics pages, alternately. 
 Very interesting exercise, that.  I recommend it.

S is a "functional"; that is, the integral of a known 
function of an *undetermined* function g.  The general form 
of what you wrote is 
                   /
                   |  4
            S[g] = | d x L[g(x),g'(x)]
                   |
                   /
where L is the Lagrange density.  Taking the functional 
derivative (the specific form of which depends upon what 
derivatives of g L depends on) gives the Euler-Lagrange 
equations for the field g.  The field g that minimizes
S[g] is the solution.
So, here, the "action" is the functional integral of the 
Lagrange density, which in your case is the density for 
the electromagnetic field, and f is some "interaction" 
term (such as with a charged particle: f = j_u A^u).

This is the way it is.  Most objects in QM are mathematical

picture of the these objects which replaces (in most cases) 
the physical intuition one has for, say, macroscopic systems.

The macroscopic interpretation, that is.  In fact, some 
systems in the Heisenberg picture (matrix mechanics) are 
so simple that you can play "games" with them without 
ever seriously considering that they correspond to the 
statistics of real objects.

You've got to realize Patrick, that we all get a little punch drunk here, 
dealing with every kind of imaginable thing day after day!  A lack of 
responsive answers not only means we lack a good answer, but want to let 
off a little steam as well!  For example, I've been making high-energy 
capacitor storage banks lately, but your requirements just didn't 
match the parts I was familiar with so I had no ready answer, but was 
still curious about a right answer (but in this case not enough to go look 
it up....) if in fact there was one....  On the other hand, a silly 
reponse to Uncle Al, well that was more available from my fingertips.  
Anyway, Steve started it.
Having sobered up, I'll mention that the energy storage obtained with a 
wide variety of real voltage and capacitance combinations always seems to 
work out to about the same energy/volume ratio, as you'd expect from 
simple physics.  Also, your energy and space constraints (300-500J ... 
3x4x7") don't look out of line to me for the best electrolytic technology. 
But your sample values (40 uF / 5KV) yeild 1000J, not 500J.  I do hope you 
find a solution and tell us about it.

 What you just wrote is a pretty good physical reason.  Notice something 
 not talked about on the Autodynamics pages: there are quite a few other 
 decay processes where the conservation laws work just fine, the problem 
 is only with those mediated by the weak interaction (beta decay).  Further, 
 even in beta decay you observe some electrons coming out that do conserve

 However, the AD equations will not conserve energy and momentum for

 Those are words signifying nothing since there is no explanation of the 
 spectrum, that is, the rate at which you see particles with a given 
 energy.  But, if we take them at face value and apply them to alpha 
 decay as well, we would expect to find a similar spectrum -- and we 
 do not.  AD is wrong.

 That is correct.  I made that point elsewhere in my comments.  We 
 are, as you say below, talking about depleted Uranium, which is the 
 isotope U-238 (technically, it can still have a low percentage of 
 U-235, but very much less than found in nature).  Nothing you wrote 
 changes this fact, or the fact that U-238 is radioactive.

 Those facts do not change the fact that U-238 is radioactive and has 
 a specific activity only about a factor of 5 or 6 less than U-235.  
 The radioactivity of natural U is hardly changed by removing some 
 of the U-235 during the enrichment process.  It may be below 
 regulatory concern when handled properly, but it is *not* Lead. 
 I think you are confused by the fact that U-235 is a nuclear explosive 
 and carefully controlled for that reason.  That fact is completely 
 independent of the fact that both isotopes alpha decay and produce 
 a documented health hazard if present as dust in the air.  My other 
 article explained the elementary ways one can protect workers from 
 exposure by even a thin coating.  However, if a worker ignorant of 
 the low-level radiation hazard and, worse, ignorant of the pyrophoric 
 properties of U metal, were to cut into the counter weight, bad things 
 would happen and the NRC guys would come trooping in with their yellow 
 booties and lengthy forms and fines.
