Good point.  The risk depends very much on how it gets into the body. 
Breathing dust produces a lung cancer risk.  The epidemiology shows a 
huge amplification of the risk with cigarette smoking, which may be 
due to damage to the lung's normal cleaning mechanisms.  Lots of alphas 
in a small area translates into a cancer risk. 
Uptake in the GI track is pretty poor if I remember the BEIR results (and 
we now know how the AEC got that data), but once it is in the body it 
messes with the biochemistry like any heavy metal.

 I am sure it is a magnetic monopole.  A very hungry monopole. 
 My recollection is that it was created in a regular old experiment 
 after something was bombarded with X MeV deuterons for N hours. 
 Pion condensates were being muttered about at the time, with a 
 local columnist wondering if the new heavy ion machine might 
 destroy the city if it made one (how he got his hands on the 
 proposal we will never know), so it was semi-plausible.

 Doesn't it want all of that energy during a short time when it 
 does its doubling thing?  Once they reach the capacity of the 
 north american grid, they *know* they are in trouble.  And how 
 do they know?  Here is the good part: theoretical calculations 
 on the MANIAC at Los Alamos!  
>So is this absolutely impossible, or not?
 Absurdly funny, yes.  The film of the sparkler run in reverse does 
 suggest a little entropy problem, but they left enough details vague 
 that it could work out OK globally.

Subject: Spin-Statistics Theorem
From: coolhand@Glue.umd.edu (Kevin Anthony Scaldeferri)
Date: 23 Oct 1996 21:19:21 -0400
I recall that some months ago there was some dicussion of whether an
explaination of the Spin-Statistics theorem existed that didn't reply
on relativistic QM.  Unfortunately, at the time I didn't pay much
attention to the thread, but now it's something I'm interested in.
So, did anyone save any of those postings, or does anyone remember
whether someone came up with a good explanation?
Thanks

On top of that, American english has continued to absorb words from 
other languages because of the continuing influx and assimilation of 
immigrants from all sorts of places.  This is made quite easy by the 
lack of a rigid grammar for the reasons noted above.  Even more 
interesting is the evolution of a Physics english for international 
publications and conferences with such weird things as eigenstate, 
where 'english' now uses a german word first introduced as a 
translation of an english term.

Not by Newton on any account :
	Absolute space, in its own nature, without relation
	to anything external, remains always similar and immovable.
	Relative space is some movable dimension or measure
	of the absolute spaces; ...
My opinion is that the "Galilean transformation" was formulated
by way of contradistinction to the Lorentz transformation. Note
that late nineteenth century physicists were certain of the
reality of a luminiferous aether, which one would think would
have been identified with Newton's absolute space.
Also, don't forget that in the ninteenth century "the universe"
was thought to be comprised of our galaxy alone. This provided
a natural absolute frame.
So, I don't know if anybody circa 1800 or so achieved a
philsophy of Newtonian relativism, but I doubt it.

A chemist plugs in a centrufuge.  He turns it on.  He watches it spin.
He repeats this process many times a day for many years.  Why is it
so hard for you to understand that he should know what it does?
I do not work with fusion.  I don't boil anything other than water.

Subject: Trajectory of a bowling ball
From: Mo
Date: Wed, 23 Oct 1996 22:46:53 -0700
I was bowling the other night and I left the same split three times in a
row. ( 3-10 ) Leaving it wasn't so bad but when I went to convert the
spare the ball hooked at just the right point and angle to pass between
the two pins. It got us to thinking of what the odds were of passing the
ball through the two pins 3 times in a row. Basically the math of
computing the angles and trajectories got way out of hand. So now I'm
here. 
Anyone someone can get me a reasonable answer I would extremely
greatful. 
Here should be most if not all the info to solve the problem.
Here is a graphical of the Pins as viewed from above.
   <---- 42 In ---->

   |       1       |
   |               |
   -----------------
The distance from each pin is 12 inches on center
ie. from 1 to 3 is 12 inches from the center of each pin
    from 1 to 2 is 12 inches from the center of each pin
    from 2 to 3 is 12 inches from the center of each pin
This for the most part makes the pin deck a bunch of equal latteral
triangles. ( Hope thats right its been a few years since Geometry) 
The diameter of the Pins are 4.766 inches at their widest point
which is 4.5 inches from the bottom. The width of the lane is 42 inches.
from gutter edge to gutter edge
A bowling ball is 8.6 inches in diameter.
Essentially looking at diagram above the ball must pass through the 3
and 0 
without touching them. 
The answer I am looking for is the area and angles at which the ball
will pass 
between the two pins. Just for the purposes of getting a good range
consider 
it a given that the ball can hook from 0 to 80 degrees. actually a hook
angle
greater then 70 degrees is not very common. although not impossible.
Hopefully I have provided all the information received. If I can get an
explanation 
of the solution that would be excellent. If there is other needed
information or if 
you wish to E-Mail the solution send a  mailto:moo@ix.netcom.com
Thanks for any help.

	Nope, that's still not it.  One more time: the words you
quoted after saying, "Thus spake Jacques Derrida" aren't his.  The
passage above ain't Derrida spaking, either in reply to Hyppolite or
anyone else.  It's Hyppolite.  And there's the trouble: you quoted
Hyppolite, but attributed his comments to Derrida.  Lengthening the
attribution to read "Thus spake Derrida in response..." wouldn't be
any help, for the simple reason that you weren't quoting Derrida.

	You're slow to catch on.  Writing "Thus spake Jacques Derrida"
made it seem as if you were quoting Derrida.  However, you weren't --
instead, you were quoting Hyppolite.  That's one mistake, and the most
blatant.  You also committed another by quoting remarks Derrida made
following a lecture and citing them as if they were part of the essay,
"Structure, Sign, and Play in the Discourse of the Human Sciences."
Then you passed this display of brilliant scholarship on to the world.
	(Incidentally, I miscounted, or rather I didn't notice that
talk.philosophy.misc had been added -- so make that six newsgroups.)

	Now that you mention it, I do recall your discussion with
Silke -- it may have slipped my mind because your references to the
text were so few and far between.  As I remember, you spent most of
the time asking Silke to summarize the relevant essay for you, which
should hardly have been necessary if you had it on hand (not that I
doubt your word).

Zeleny:

	This isn't a question about format.  You set out to attack
Derrida, but right off the bat you wrote, "Thus spake Jacques Derrida"
and immediately proceeded to quote the wrong guy -- not an auspicious
beginning.  Then you quoted comments Derrida made in discussion and
made them seem part of the famous essay, "Structure, Sign, and Play."
(Reading it in your copy of _L'ecriture et la difference_ might have
prevented that error, assuming your mistake was unintentional.)
	In short, your claims to rigor are hollow.  You can't figure
out who you're quoting and you misidentify basic texts, apparently due
to a lack of familiarity with their contents.  None of which has any
visible importance to you.  So while it was worth my time and trouble
to correct your errors, there's little else here for me to do.

I guess from this we can roughly calculate the speed of light in
furlongs per fortnight:
1 furlong = 10 chains = 200.12 metres.
Number of seconds in fortnight = 60 x 60 x 24 x 14
                               = 1.2096 x 10^6 
Distance light travels in fortnight = 2.98 x 10^8 x 1.2096 X 10^6
                                    = 3.605 x 10^14 metres
Hence, speed of light = 3.605 x 10^14 / 200.12
                      = 1.8012 x 10^12 furlongs per fortnight
I hope someone finds this useful!

Judging by the quote, this a book I should read.  Anyway, there is a 
lot here that I can identify with, especially regarding the broader 
rhytms at the deepest levels.  And I would apply the same thinking to 
the history of ideas.  Concepts indeed evolve over time and their context 
may change and broaden.  To the uninformed observer many of the 
changes may apperar as discontinuities.  But, this is very rarely the 
case.  Looking deeper underneath the surface one discovers the deep 
currents which keep pressing till, at some point, the dam bursts and 
the hitherto arid land becomes inundated.
Not recognizing the continuity means missing a big part of the 
picture.  Of course contemporary accounts tend to stress the change, 
not the continuity.  That's just human nature, we tend to tune out the 
slow, gradual build up and recognize only the rapid changes.  Viewed 
from some perspective, though, things look different.

        In at least one case, anyhow.  And of course there have been
hoaxes in the sciences.  Are they any basis for broad generalizations?
Do they show that all other work is bad, in either the sciences or the
humanities?  Of course not -- but that's what Sokal's hoax is supposed
to demonstrate about the latter.

You must realize (difficult as it may be) that what Newton though of 
the subject has nothing to do with the issue, only what's in his 
physics is relevant.  And there is no absolute space in F= ma, this 
equation remains the same in all frames moving at constant velocity 
one to another.

Actually, the aether got into physics as an attempt to solve the 
crisis brought up by the electromagnetic theory. Maxwell's equations 
aren't invariant under Galilean transformations, thus creating the 
impression that there may be an absolute frame after all, namely the 
frame in which they are valid.  This is the same crisis that 
eventually got resolved throughtheintroduction of relativity.

Depends on the context.  One can be "faced" on the basketball court, as
well as in a bar.  In the former case, the word seems (in my experience)
to derive from the exclamation "In your face!"

You've been reading too much moggin lately :-)  I suggest you stop 
relying on his musing, go back to my posts and read for yourself.  
The above is exactly the sense in which I'm using generalization.  The 
modifications introduced by Einstein, for example, extended the 
applicability of then existing scientific theories to a wider realm, 
without infringing on their applicability to the realms which were 
previously covered.  Where is the supposed semantic problem here?
This business of "two different meanings of generalization" is a 
mythos invented by moggin as a smoke screen, to cover his retreat.  I 
didn't bother to comment on it when he brought it up, assuming that in
view of previously posted material the laughability of this excuse 
should be obvious even to a casual reader.

Hardly.  If I ask you "what time it is now" you'll say "quarter to 11" 
or, if you've already been brought up on digital watches, you may say 
"it is ten forty four".  I rather doubt that you'll mention seconds 
and I'm sure that you won't get into fractions of seconds.  But this 
is not a scientific exchange, that's standard usage.  So, according to 
the view you seem to champion, you answer is "wrong".  Similarly, if I 
ask for your height you'll give an answer rounded to the nearest half 
inch (or the nearest centimeter, being an European).  Again, knowing 
that it takes infinite number of digits to get absolute accuracy, this 
answer is "wrong".  And, again, this is not a scientific exchange.  
So, you see, this concept of "wrong" as used by moggin is not only mot 
in use in science, it is also not accepted in general usage.  So, 
where is it valid?

No doubt. We are still looking at the analogy. Newtonian mechanics was

Moggin was mobbed for practicing sophistry.  The subject matter
was tangential, except like all good sophists, he had to choose a
subject that would attract interest.  Moggin worked the
differences in vocabulary into his sophistry, but even these were
tangential to the issues.  (Sophistry is partly a guiding of
discourse that keeps the tangential center stage.)  Look at my
signature.  Yes, it is literally true for some meanings of
'wrong,' but it is purposely crafted to suggest a different (and
false) reading.
Perhaps Silke may not recognize sophistry, or perhaps she finds
nothing wrong in it.

The speed of light in vacuum is fixed for all observers.  This limitation 
on the speed of information transit remains in materials, but light is 
slowed down by an interaction with the material through which it is passing.

Um, why?  I am giving you the benefit of the doubt, and assuming that by
"to question and revise the devine nature of christ" you mean "to accept
that christ has a devine nature, but to question and revise what that IS
and what it MEANS."  Otherwise, of course, your analogy is just plain
wrong, since it is NOT possible for physicists (or anyone else) to decide
that space and time don't exist in any sense.  So, why can't a christian
question the meaning or nature of christ's divinity, in the same way that
a physicist might question or revise the best way to model "space" or
"time"??
  To

How so?  I am about as far from an expert on christianity as you are
likely to find anywhere, but it seems to me that one of the central tenets
of the faith is "Thou shalt love the Lord your God with all your heart,
all your mind, and all your soul." (Probably misquoted.)  That is a
statement of the form "it is good to behave...".  It is also a statement
open to wide interpretation, since it's not at all clear what precisely it
entails in practice, as a guiding commandment for living one's life.
I don't see any sort of behavioural recommendation in the phrase "the
nature of space and time."

No. What a silly thing to suggest. I cannot think of any philosopher 
whose sentences cannot be made to look silly by taking them out of 
context; when it comes to sentences spoken off the record, as it were, in 
a matter outside their field, it's so easy that only someone rather

I trust you won't find much of an attack in the above, be it personal 
or institutional.  We simply get sidetracked so much in this 
discussion that .  The original thread already gave birth to half a 
dozen subthreads anf tracking the issues becomes complicated.  So I tried 
to abort the "Fuel pumps and transmissions in the engine of physics" 
subthread, before it is too late.

The water vapor in the atmosphere is filtering out almost all the other
radiation; only the region where water does not or only minimally absorb

I'm not Silke, but I'll take a stab at the question.  There are those who
would say that for aesthetics to BE aesthetics, it must take "The
Aesthetic" to be a privileged realm, which in this context simply means a
realm which is not reducible to, say, normative psychology, neurological
mapping, or ideology critique.  There is an investment, empirically
observable but difficult fully to account for, in preserving the
(illusory?) belief that Art is special in some sense, and that scientific
and/or ideological accounts of it are missing something crucial.  Perhaps
the simplest way to put it is just to say that aesthetics takes Art to be
its object of study, whereas both science and ideology critique take art
to be their object.  The latter believe that the capital A obscures clear
perception of the object, whereas the former sees it as integral to the
object.
Thus, anyone who accounts for aesthetic reactions either scientifically or
ideologically is by definition killing aesthetics.
