Sounds like a neat project. I'm strictly amateur, but I'd say
you want to prevent heat transfer through convection, conduction,
and radiation. Tape a magnet to the cube and use an opposing magnet
to levitate it, eliminating conduction. Put this assembly inside
a stoppered flask and pump out the air, eliminating convection.
Finally cover the whole thing with fabric opague to light to
eliminate radiation. 
The above should easily stay cold for 5 hours. You might even
be able to skip the vacuum (which can be tricky) and succeed
with just the maglev and light cover.
Good luck

The thing is, though, that it's the good ones who don't get stressed, and
don't get ill. If you are not sitting on a vulnerable position, crapping
yourself about covering your risk, or clawing back last weeks losses,
things aren't too bad.
All the traders I know seem to be pretty laid back about the whole thing.
Of course, they could just be hiding it well, but it doesn't seem to be
that way.

Again, things are not too bad. One of the traders I know runs the five
miles to work every day, a few others go immediately to the gym after
work, and put in an hour before they go home.
Of course, this is not always the case. Just about every member of my old
boxing club has now moved on to the city, and they have certainly changed
shape from their competitive days. The thing is, though, that they are
planning to retire before they get old, and so are willing to put up with
whatever it takes through the ten or twelve years that they are working.
I hope that I am able to avoid getting stressed or losing my shape. It all
depends, of course, on whether I have got what it takes to rise above the
other traders. Only time will tell.

I think F=ma is not so much a law as a definition.
The real laws of newton were that:
1) If  a body is not disturbed, it will stay where it is or move forever 
with constant velocity
2) The conservation of momentum: that every body has a quantity called 
mass, such that in every collision,
m1v1+m2v2 will stay constant throughtout.
From 2) one can define momentum & hence force.

Some of the readers of this newsgroup might be interested in a FAQ
just posted to the rec.arts.startrek.tech newsgroup.  The FAQ is
called "Relativity and FTL Travel".
Basically, it is a straight forward look (written for a non-technical
person to follow) at Special Relativity, General Relativity, and the
problems and "solutions" one finds when considering faster than light
travel.
For more information, read the "Introduction to the FAQ" portion which

Congratulations, C. J. Clark! You have managed to come up with a totally
new theory of harmony, a theory that is totally unrelated to all the
classic treatises of the past.  Moreover, you have employed standard
terms--such as consonance and resonance--in a way no one else does.  I
particularly loved your statement: "Good music bases 99% of its melodies
on major and minor scales, Greek modes and their derivatives, pentatonic
or any formal scheme of scale based on intervals other than seconds." By
the way, on what does bad music base 99% of its melodies?  Did you, by
any chance, study harmony with the great theorist Albert Silverman?

Is it legal to chill the container before use?  I would expect several layers

Or just keep it outside . . . where are you?

I used the newtonian formula for orbits:  r = r0/(1 + e cos theta).
The only difficulty was to calculate the rather complicated expressions
for "r0" and "e" (eccentricity), given only asymptotic speed and perihelion
distance. I made no assumptions about invariant light speed, but the speed
increase in this model is very small anyway.

But the beam of light is really bent, since it's angle is changed.
Consider this thought experiment: space is empty except for the sun,
a powerful laser, and me. Both I and the laser are at very great
distance from the sun, say several hundred thousand light-years.
Without the sun, the laser beam would have a certain incoming
angle in my region of space, but with the sun where it is, the
incoming angle is different. Even in GR, where the path of the
laser beam is at all times and places a geodesic, there is a 
real bending effect as seen from the faraway observer.

Velocity is both magnitude (speed) and direction. Acceleration
can change only one (speed change) or only the other (rotation),
or a little of both. I think Divergent Matter is an attractive
idea, but it needs to explain rotation and not only speed change.
I still can't see how this can be done without introducing some
new element into the theory.

Agreed. Myself, I am only a layman who likes to play with math I

works is deep and serious.

Subject: CRYSTAL polarizabilities

Hello all:  just wondering if anyone is familiar with the
Daresbury/Torino CRYSTAL (periodic Hartree-Fock) package..
I need to know a few things and am having one heck of a time
getting through the manual! ;-)
1. How can one get polarizabilities (alpha) (etc)?
(let's first consider just a simple system: the F- ion
at the origin)
I have naively been trying to create 2 H+/- "point charges"
at a large separation: then use perturbation theory to find:
alpha = (energy(with field) - energy(no field))/field^2
However, I'm not sure of the effect of the H basis functions.
Moreover, I'm too thick to be able to convince myself of
the correct units for the field and so on (in general all the
stuff is in atomic unit - distances in Angstrom).
2. Is there a way to use simple bare point charges or to
"switch on" an E-field ?
Any help much appreciated!
Patrick
The input I've been trying to use is attached.

Light has its largest velocity in vacuum, but the speed decreases in more
solid material (for example glass or water) 
So it's possible that an electron can move faster than light (observe that
in this case it's the speed of light in the solider material we talk about)
in solider materials, i've read that neutrinodetecors consists of large
tanks filled with some fluid 
(which, of course, are solider than vacuum :), therefore we can assume that
an electron which have been hit by an neutrino can travel faster than the
lights speed in the actual material.
Study your science magazine and check if they didn't mean "Faster than the
light speed in the fluid",

No, no, no. This may get me into an argument. but--
F = ma  is -not- a definition of force.  It is -not- an identtity, it
is a -law of motion-.  It is a second-order differential equation that
relates the motion (i.e., kinematics) of a particle to the force
(i.e., dynamics) acting on the particle.
In fact, force is, from the standpoint of logic-and-axiomatics, an
undefined concept in classical mechanics.  This is not to say that we
don't know what force is; there are a variety of classical 'force
laws' such as the elementary laws of gravitational force and the
electromagnetic Lorentz force,  the not-so-elementary force laws for
frictional, pressure, and viscous forces, as well as (my favorite) the
fictional coriolis force.

This has probably been said many times before, but are you aware that
quantum mechanics and cosmology _demand_ that astrology, meaning the
effects of the planets on the lives of humans, is a genuine effect?
Viz: the Copenhagen interpretation states that once two quantum
mechanical particles have interacted, they form a single quantum
system for ever after, with (apparent) FTL signalling and so on (cf.
woolly EPR explanations by bewildered QM exponents) which includes
instantaneous effects on parts of the system by other parts which may
be physically separated by large distances. 
(Hands up if you can see where this is leading yet...)
Furthermore, as matter/energy cannot be created nor destroyed (barring
uncertainty relations, pair production and the like), only changed in
its state, all matter currently in existence must have been present in
the Big Bang and subsequent expansion. As all matter in the universe
was once crammed into a space smaller than the Planck length, all
matter in the universe has interacted quantum mechanically with all
other matter in the universe and so the whole shebang is one large
interacting quantum system.
Which means that the collections of atoms that form the planets have a
very definite quantum mechanical effect on the collections of atoms
that form people.
Food for thought... hope you don't choke on it!

Yeah, whatever.  
Absorption of a neutron by U-238 leads to two beta decays to form 
Pu-239.  One particle in, two particles out.  Hmmmm....sounds like 
entropy is increasing.
BTW the neutron could come from the spontaneous fission of U-238 (a

	I think that much of the new wealth in current growth areas
of the economy wouldn't exist were it now for PhDs, the academic system
and govermental support of R&D.; Technologies like OOP, The Internet,
and GUI interfacing would not have existed if they were to be developed
solely on the short-term thinking of the average businessman in a large
or small company. All of these technologies had to be pioneered first
by eggheads in research environments protected from the whims of the
market, quarterly reports or investors. Much of what is successful
business is on the heels of proven technologies. The U.S. needs to be
a leader in new technology development to remain competative in
world markets. This absolutely depends on a strong academic and govermnet
funded R&D; institutions. We cannot depend on private companies to take
the risks associated with long-term technology development for which
they are risk adverse.

	Yes, I get the picture, companies have discovered a way to
push risk out the door in the guize of "opportunity" for outsourced
skills. Individuals are being turned into entrapaneurs whether they
want to or not. This is the main impact of computers and high-tech on
the labor market. It allows large organizations to slim down, reap
the benefits of their position while reducing labor costs and risk.
This is a revolutionary change that will have grave political and
social consequences, I think. People are discovering that the
private sector not only doesn't make promises, or can't keep
any that it may have made in the past, but that it depreciates
their skills and worth. They will react badly when the realization
hits of who really benefited from the massive changes taking place.
It wasn't the majority of people. The income distribution changes
in the U.S. in the past 20 years is evidance that so-called
free market economics benefited a small minority and that it leads
to winner-take-all processes that disadvantage many more then it
benefits. It is the power of timly access to information and the
flow of information that causes this.

I think it depends on how you define "time", or rather how you
define the rate of time flow.
My favourite example is a clock made out of a flashlight, a mirror,
and a photodetector:
                   /                          |
       Flashlight |                           |
                   \                          |
                                              |  Mirror
                  ]                           |
    Photodetector ]                           |
                  ]                           |
                  <------- distance "d" ------>
The flashlight sends out a light pulse, and a clock tick is defined by
when the light comes back to the photodetector. The clock period is 2d/c
since 2d is the distance travelled by the light. (d is much larger than
the distance between flashlight and detector)
If we watch another similar clock that is moving with speed "v" in a
direction perpendicular to the line that defines the distance "d",
we will see the light pulse moving in a zig-zag fashion. In that clock
the total distance travelled by the light pulse will be longer than 2d.
Therefore the clock period will be longer too.
Using Pythagoras theorem and simplifying, we get (2d/c)/sqrt(1-v^2/c^2).
If all physical processes are affected by motion the same way as this
simple clock, then time itself will seem to have slowed down as seen
from an outside observer. But within the rest frame of the clock, no
slowing down of anything or any other special effects are noticed.
This is the "transversal" relativity effect. The "longitudinal" effect
can be shown in the same way, but with motion in the direction of the
beam of light. The longitudinal effect causes length contraction and
disagreement on the synchronization of clocks along the longitudinal
axis. To see how the original clock slows down as observed from the
second clock, we need to take both the transversal and the longitudinal
effects into account. Then the whole situation becomes symmetric, and
this is why it is impossible to claim that one observer's definition of
time or space is more "real" than another's.
Well, that's my view of things. Followups to sci.physics.relativity.

Not true at all!  The opportunities for the non-degreed person are 
greater today than they ever were.  When we were mostly farmers, generally we 
had to stay farmers, because opportunities for education or intellectual 
broadening were limited.
There are countless examples of people with minimal or intermediate education 
doing very well in business.  Pursuing a PhD and becoming a businessperson are 
two different life tracks, with many failures and a few successes in each.  
They're not mutually exclusive, either.  Some heavily-degreed types do well in 
business.  A businessman is unlikely to cross over and become a scientist, 
mostly because science is more structured.  You have to have that degree and 
put in your time before you can 'make it' in science.  The business world is 
wide open, and anyone with native intelligence and guts (and a little luck) 
can succeed.

The acceleration field produced by the rocket's turnaround is not a
physical explanation of the twin paradox. The acceleration field, as
seen from the rocket, will produce lots of strange effects including
the effect of immediately changing the velocities of large galaxies
far away, by just turning a knob in the rocket's control panel.
A better explanation is found by analyzing the rocket's motion from
an inertial frame. It doesn't matter which inertial frame. If we look
at both twins as they move from event "1" to event "2", where event
"1" is where they take separate paths, and event "2" is where they
meet again, it can be shown that for the twin in the rocket, some part
of his path between the events will always be time-dilated to a
greater extent than any time dilation for the other twin.
That acceleration in itself does not explain the twin paradox can be
understood if we let the "earth" twin sit in another rocket ship which
accelerates back and forth between the earth and moon all the time,
without ever reaching a speed of more than 100 km/s or so. The twin
in the starship on the other hand, may spend only a fraction of the
trip in accelerated motion, and he will still be the one that has
aged the lesser amount when the twins meet again.
The only explanation that acceleration provides is that acceleration
is what causes both the velocity increase and change in the direction
of motion that lets the twins meet again. But we get exactly the
same effects by using three inertial frames that synchronize their
clocks pairwise at three different events (departure, turnaround,
and return), with no acceleration occurring anywhere.

Interestingly enough, while the US was busy getting bogged down in
Vietnam, the UK was engaged in fighting in Borneo, in remarkably similar
political situations. The UK military position wasn't as good as that of
the US; the Borneo border was massively longer than that which the
Americans had to deal with, and the terrain very much harder.
Nonetheless, the UK was successful.
One can debate why this should be; however, there was no great "anti-
war" debate in the UK. I suspect that this was in part because of
different attitudes.

So your model of good music consists of harmonies that are derived

While I would be the first to argue that there are serious problems with
what passes for a democratic system of government in the US, I would have
to point out that while it is true that the entire government in the UK
changes on a fairly regular basis, much of the UK's foriegn policy is
dictated by career diplomats. Unlike the US system where, as I understand
it, the President can appoint anybody to be an ambassador, all diplomats 
in the UK are
civil servants, who have actually received training for the job that they
do. Ambassadors especially would have had many years of experience before
reaching their posts. Although the government has some influence in who
gets promoted and who doesn't, there are no such things as political 
appointees. John Major (or Tony Blair if you are reading this a week or
two from now ;)  ) cannot say that he wants X random person from outside
the service to be ambassador to Mongolia. He can choose one person from a
list of suitable people, but thats about it.
The point I'm trying to make is that the civil service is far more
powerful in the UK than in the US, and this leads to a certain amount of
stability/stagnation from government to government, particularly in
foreign affairs and trade relations (if indeed there is a distinction
between the two), and this compensates for the more frequent change at
the helm, so to speak.
In a parlimentry democracy, there seems to be a need for a conservative
civil service to keep the whole show on the road from year to year; the
politicians do all the talking and the civil servants really run the
country. Although it can be argued that the Vietnam conflict was prolonged
by bad advice, where did this advice come from. Was it from ambassadors
and civil servants, or was it from the military/industrial complex as
Mr. Stone would argue? If the later is the case would a parlimentry system
really have made a difference?
As for comparing the two systems, the US is not a true democracy. Because
of the Electoral College system, the President is not actually elected
by the citizens themselves. The electoral college of a state votes
for the President based on the recomendations of the people of the state,
but that can by no means be called one person, one vote. A citizen votes
to mandate a representative to vote a certain way, but that citizen
doesn't directly vote to put the president in the White House. CNN also
has alot to answer for, while people in the West Coast and Alaska and
Hawaii are still voting, CNN was announcing results from the East Coast
and declaring an outcome, which obviously discouraged voters in the West
from going to the poles. In the UK and here in Ireland, no results can
be announced until all polling stations have closed (yes even though we
are very small, outlying islands vote on different days). Yes there are
exit polls conducted, but these only give an indication, not a result.
But I digress, 'cause CNN wouldn't have been a major factor in the
Vietnam conflict. 
The UK system of Parlimentry Democracy isn't all that democratic either,
based on a 'first past the post' system. Each constituancy has but one
represntative, and the person with the most votes wins. This means that 
even if the majority of voters voted against a candidate, they can still
be elected if they get more votes than anyone else individually. It is
therefore almost impossible for candidates from the smaler parties, the
Greens, the Liberals, Natural Law or Monster Raving Looney Party, to
ever get anyone elected. It also has a detrimental effect on candidates
running as individuals, rather than on a party ticket.
Here in Ireland, as in other true democracies ;) we operate on a
Proportional Representation system. This works by having more than one
Representative per constituancy, usually between 3 and 5. The total
valid poll is calculated and a quota is tallied, I think its 50% +1,
but I'm not sure. When voting, people vote for the candidates in order
of prefernce, for example, Bill Clinton first, Ross Perot second and
Bob Dole third. They then tally all the first prefernces. If anybody
has reached the magical 50%+1 quota on the first count, they are elected.
What happens then is the distribution of their surplus. All their second
preferences are given a certain value, and added onto the results from
the first round of those who still remain. This goes on until all the
vacancies have been filled. If no-one reaches the quota during any given
round, they eliminate the person with the lowest tally, and distribute
their other prefrences between the remaining candidates. Yes, it is
a complicated system, and counts usually go on well into the night and
next day, particularly if, as they usually do, an eliminated candidate
asks for a recount. What this does mean, however, is that there are a
wide range of people elecetd from many different parties, or none at all,
and the Dail, our parliment, is actually representative of the way people
actually voted. Yes this means that Coalition Governments are the norm,
but this means that the views of the majority of the population are
actually reprented in Government. At the moment our Government is a
coalition of three parties, centre-right, centre-left, and left, the
last government was right and centre-left. Mix and match is the name
of the game.
But back to the point, a UK style parlimentry government would not, in
my opinion, have finished in Vietnam any earlier than the US did in OTL,
however, a parlimentry government based upon a PR electoral system would
have, as it would have been more representative of the views of the people
and would have represented the strong anti-war movement prevelant at the
time, rather than the intrests of the military/industrial complex.

I would suggest you try a milk bottle and some nice chemical process to evacuate it, creating a 
vacuum flask. The ice cube could keep nicely inside a modest vacuum if it is wrapped so it can't 
evaporate. I assume that you will need to displace the air with something first. I know that you 
can get a pretty good vacuum with steam, but obviously you would then have to let it cool before 
you could store the ice in it. I think a good epoxy glue would seal OK for a few hours. You don't 
really need a hard vacuum to get the insulation value up where you need it. Oh, BTW, you could just 
cheat up a storm. Put it in some styrafoam inside a bottle inside a container of ice and salt. This 
would tend to freeze it up. Could also pull a vacuum on water untill it starts to freeze, then your 
ice will keep nicely. Also, as I recall, there are a couple of chemicals that are strongly 
endothermic and could be mixed to make a freezing mixture for you.

I think that either music or speach is an equally good signal.
However, I seem to recall an "explanation" of this experiment to
the effect that the receiver is actually extrapolating the signal
in some way, thus giving the impression of faster than light travel.
Given the tiny time delay, the music still sounds reasonable.
