897.1 | Is ignorance an epidemic? | SEINE::RAINVILLE | Rest of the future-over the edge! | Sat Oct 29 1988 06:53 | 23 |
| More than 450 years after Copernicus proved the Earth revolves around the
sun, millions of adult Americans seem to think it's the other way around.
A phone survey of 2,041 adults conducted in July asked 75 questions
designed to test knowledge of basic science, margin of error 3%
Asked whether the Earth goes around the sun or the sun around the Earth,
21% replied incorrectly, 7% didn't know. Of the 72% correct, 45% said
it takes one year for the Earth to orbit the sun, 17% said one day, 2%
said one month and 9% didn't know.
Asked (true/false) if lasers, an essential component of SDI, work by
focusing sound waves, 36 % answered correctly, 29% incorrectly, and
35% didn't know.
In an election year, in which candidates are discussing issues like
the Strategic Defense Initiative, acid rain, the greenhouse effect and
the space race, the survey indicates many Americans have little idea
what they are talking about.

WEll, if domination, control, manipulation, better thans,

NO, he isn't harmful. If, on the other hand, you don't

| In my opinion, what Morton does is to rattle people enough that
their TRUE selves will come out. Morton himself, is a show. There
is a definate method to his madness. He's entertainment. The people,
however, are speaking for themselves. He will very willingly give
them enough rope (or force it on them) to either support themselves
or hang themselves. No matter what Mort does, it's usually very
clear at the end of a show who the real people are and who the phonies
are.

I've only seen a small portion of one show (yuck) and choose not

it seems to me that all he does is turn peoples ego's themselves and

897.5 | What Entropy Means to Me (appologies to Piglet). | ERLTC::COOPER | Topher Cooper | Mon Oct 31 1988 13:12 | 68 |
| > Entropy being the observed tendency of nature, two entities seem
> capable of reversing it, intelligence and crystals, are there
> others?
I'm not sure what this question has to do with the rest of the
posting but I'll answer it anyway.
The second law of thermodynamics states, roughly, that in a closed
system which is sufficiently close to kinetic equilibrium entropy
will not decrease.
When one of the two conditions of the law are violated, then it
is commonplace for entropy to decrease. In effect, the degradation
of organization outside the system is "borrowed" against to
create local decreases in entropy (increases in organization).
"Water always flows down-hill", but if one looks at a swiftly flowing
stream one can find eddies where some of the water is flowing
up-hill at any given moment.
The most commonly cited example of an anti-entropic system is
*any* living thing (not just intelligent ones). A plant, for
example, takes the fairly highly entropic carbon dioxide gas
and water and turns them into much more highly structured
sugar molecules. It does this by taking advantage of the large
energy differential between the sun and the plant's leaves.
On a different time scale, one can look at the sweep of evolution,
with the slow development of constantly more and more complex
life forms as the same kind of situation -- powered, ultimately,
by the same disequilibrium between the earths biosphere and the
suns surface.
It is pretty easy to find examples of local decreases in entropy
when you look at situations which are not almost in a state
of equilibrium. A frequently cited, non-biological example is
the development of Raleigh-cells. If you take a fluid, such as
water, and place it between two plates, heat the bottom plate
and cool the top one, and look at the way that the fluid circulates
you will find that it forms nice neat geometric convection cells
-- specifically hexagonal ones, with the fluid rising in the
center of each cell and falling to be reheated at the edges.
Other more "natural" examples would be the formation of planets
stars, galaxies, etc. by accretion and aglomeration (whatever
theory you accept to explain that process of accretion and
agglomeration). The creation of the lighter elements in the
immensly (by Earthly standards) unbalanced conditions of a
stellar interiour, and the creation of the heavier elements in
the immensly more (by ordinary stellar standards) unbalanced
conditions in a supernova, provide some other examples.
I'm going to have to think some more about it (thermodynamics
not being my strongest area) but I rather strongly suspect that
crystals -- despite appearances -- are not particularly anti-entropic.
Rather I would guess that the appearance of regularity in what
we consider important and relatively concrete (the positions of
the atoms) occurs so that the overall entropy of the system including
components which seem less concrete to us (e.g., the energy fields)
increases. Crystals form because the crystallyn form represents
the state of minimum internal energy and systems "roll downhill"
to energy minima. But they "'roll downhill' to energy minima"
as an expression of the second law of thermodynamics. A higher
energy state means internal energy differentials which represent
lower states of entropy. The formation of the crystal represents
a process by which energy differentials are decreased (equals
entropy is increased).

897.6 | "Entropy", as a concept, doesn't make sense everywhere. | CTHULU::YERAZUNIS | Gordian Knot Lock Co. | Mon Oct 31 1988 14:29 | 48 |
| re .5 (Topher)
The trick is that thermodynamics is a statistical model of the
universe, and for the cases where statistics works well (large numbers
of sample points, continuous or nearly continuous linear interactions,
nothing relativistically large or quantum-small) the thermodynamic
model of the universe works perfectly. Locally, entropy
can decrease, but over the ENTIRE SYSTEM (which might be as
big as a county, a planet, or a solar system) entropy continues
to increase.
For example: plants grow, volcanoes erupt, fires burn,
steam expands. The common things we see every day.
Classical thermodynamics breaks down in those circumstances where
it's basic assumtions break down; in the case of masses that are
relativistically large or fast, or in the case of interactions which
involve such small quantities that Planck's constant (and the other
gruesome parts of quantum mechanics) become apparent.
For example: recoilless absorption of gamma rays in
isotopically pure cobalt, the direct conversion of
mass to energy as the mass falls into a rotating
black hole, superfluidity of flow in liquid helium II.
Not the most common things in the world...
-----
The bottom line is that entropy is subject to an uncertainty like
that of distance. As the system becomes more and more askew from
the original (statistical) model, the entire concept of "entropy"
suffers a Heisenberg-like uncertainty effect.
What does "entropy" mean in a system of one electron and one proton?
Energy is still defined, volume is still defined, temperature is still
defined, but the entropy of such a system (although still defined)
doesn't have any real meaning.
It's like saying "this electron is here"; the statement of an electron
"being" anywhere isn't just wrong, in the quantum-mechanical universe,
the statement itself is meaningless. Electrons aren't anywhere
in particular... nor can one discern any particular electron from
any other electron... nor does the word "here" mean anything like
what humans mean when they say the word "here".

The social purpose is entertainment, pure ans simple. For some,

Who ways lasers are _essential_ in an SDI systyem? I can think
of several SDI techniqies that don't require lasers at all. The
point? Whoever did the report should bone up on his or her science
and/or technology.

I think, Steve, that you are demanding a bit too much precision.
The original SDI concept -- the impenetrable "peace shield" --
consisted of multiple different technologies working in perfect
concert. The supposed practicality of the system as a whole relied
on almost all of the different component systems working (almost,
because there were a few alternatives proposed). Several of those
systems involved laser systems -- big or bigger. Lasers were
without question an essential part of the original SDI system
(which is what most people, including Reagan, seem to think the
military is still talking about). Indeed, there is very good
reasons to believe that the whole SDI concept was cooked up by
Teller to assure large amounts of cash would be available for
his pet development projects -- most of which involved big lasers.
A second reasonable -- though loose -- interpretation, given the
context is that an understanding of lasers, their capabilities
and limitiations is essential in making informed decisions about
election issues.

Point is, the clause was a throwaway. One might well say, "...
lasers, essential in bar-code-scanning cash registers ..." which,
given the current state of the art, is accurate.
My problem with such throwaways is that _in the context of trying
to show the ignorance of the general public_, the reporter makes
his or her own technical gaffe.
The point the reporter was trying to make was that if the voting
public didn't know whether sound waves, light waves, or whatever,
was central to a laser's operation, _and_ that lasers were essential
to an SDI system, the poor, unwashed voter was operating in total
ignorance as to the practicability of any proposed SDI system.
The suggestion was that the questioner, who _of course_ we assume
knows the mechanism, we also assume _of course_ is better informed
about the voting issues than the poor slob who doesn't understand
the lasing function.
