Again, what a load of crap! 
"A most *VICIOUS* *EVIL* and *TREASONOUS* lie." This is good, apparantly she is the 
first politician in this country to lie in an election. Jeezzz! Bob Hawke and Paul 
Keating sucker punched people like you for years. And now old Johnie is doing the same. 
She probably believes that she IS fighting for equality, but because you don't happen to 
agree with her she is the Evil Harradan from Hell.
She was elected on primaries. The two major parties have decided to swap preferences to 
ensure that she doesn't get elected again. There are plenty of "experts" who are of the 
opinion that she will be elected again on primary votes alone anyway. 
Her supporters have already stated that if opinion polls in her electorate show that she 
can't get elected, then she may stand for the senate. In this case she WILL be 
re-elected.
She is here, get used to it. She keeps the media salivating and gives good little social 
revolutionaries someone to hate. 
By the way, what do you mean by "fair means or foul"?

Hello,
I've looked everwhere for a translation of Lagrange's masterpiece
MECANIQUE ANALYTIQUE but have had absolutely no luck.  I can't
even find a copy in the original French.  Can someone please
help me out?  
Thank you,

Subject: Momentum and Impulse?
From: "Sam Bergin"

I'm sure that a question such as what is momentum and what is impulse
would seem strange to those Physicists with a string of letters before
your name.  However I wish to know because I have an exam on Monday.  If
anyone can help please write me thanx :-)

   They're easily comprehensible.  The question is, what makes you think
they're relevant?  Are you shaking your finger at Newton's colleagues for
not properly following your "rule of science"?  Or do you believe you're
arguing with me?

   That's an interpretation, although hardly worth the name.  As I've
already pointed out,  "action-at-a-distance" is an explanation of the
workings of the remote control (albeit an empty one).  I ask, "Mati,
how does the remote work?"  You tell me, "It exerts a force."  I say,
"Mysterious forces -- yeah, right.   O.k., how do _they_ work?  You
answer,  "Action-at-a-distance,"  and I reply, "You sound more like
a psychic than a physicist!"  If you really  thought like Joe Friday, 
then  you'd have said, "Well, it just works,  that's all.  Damned  if I 
know  how.  Just don't forget to change the batteries."

   What "fact"?

   Again, your self-evaluation has no relevance here.  And I see you
accept my point, since  you're now claiming to have a philosophy
that's superior to any philosopher's, while before you argued that
physics was ruled by evidence, not "philosophical ideas."
moggin:

   I don't care _what_ your feelings are -- your assertion is false for
the reasons that I've offered.  (I was wondering if you bothered to read 
the posts you replied to -- thanks for supplying the answer.)
Mati:

   You're being duplicitous again.  You cited the religious motivations of
Maupertois or Fermat  (you weren't sure which) in order to deny that
mysticism had a meaningful relationship with physics.  You did poorly.
Not only were you uncertain who you were actually talking about, you
had nothing to say about either their religious beliefs or their work as
physicists.

### Answers to Frequently Asked Questions about Fusion Research
-----------------------------------------------------------------
# Written/Edited by:
     Robert F. Heeter
     
     Princeton Plasma Physics Laboratory
# Last Revised February 26, 1995
-----------------------------------------------------------------
*** A.  Welcome to the Conventional Fusion FAQ!  
-----------------------------------------------------------------
* 1) Contents
  This file is intended to indicate 
     (A) that the Conventional Fusion FAQ exists, 
     (B) what it discusses, 
     (C) how to find it on the Internet, and
     (D) the status of the Fusion FAQ project
* 2) What is the Conventional Fusion FAQ?
  The Conventional Fusion FAQ is a comprehensive, relatively
  nontechnical set of answers to many of the frequently asked
  questions about fusion science, fusion energy, and fusion
  research.  Additionally, there is a Glossary of Frequently
  Used Terms In Plasma Physics and Fusion Energy Research, which 
  explains much of the jargon of the field.  The Conventional 
  Fusion FAQ originated as an attempt to provide 
  answers to many of the typical, basic, or introductory questions 
  about fusion research, and to provide a listing of references and 
  other resources for those interested in learning more.  The
  Glossary section containing Frequently Used Terms (FUT) also
  seeks to facilitate communication regarding fusion by providing
  brief explanations of the language of the field.
* 3) Scope of the Conventional Fusion FAQ:
  Note that this FAQ discusses only the conventional forms of fusion
  (primarily magnetic confinement, but also inertial and 
  muon-catalyzed), and not new/unconventional forms ("cold fusion",
  sonoluminescence-induced fusion, or ball-lightning fusion).  I 
  have tried to make this FAQ as uncontroversial and comprehensive
  as possible, while still covering everything I felt was 
  important / standard fare on the sci.physics.fusion newsgroup.
* 4) How to Use the FAQ:
  This is a rather large FAQ, and to make it easier to find what
  you want, I have outlined each section (including which questions
  are answered) in Section 0, Part 2 (posted separately).  Hopefully it 
  will not be too hard to use.  Part (C) below describes how to find
  the other parts of the FAQ via FTP or the World-Wide Web.
* 5) Claims and Disclaimers:  
  This is an evolving document, not a completed work.  As such, 
  it may not be correct or up-to-date in all respects.  
  This document should not be distributed for profit, especially 
  without my permission.  Individual sections may have additional 
  restrictions.  In no case should my name, the revision date, 
  or this paragraph be removed.

* 1) Obtaining the Fusion FAQ from Newsgroups
  Those of you reading this on news.answers, sci.answers, 
  sci.energy, sci.physics, or sci.environment will be able to 
  find the numerous sections of the full FAQ by reading 
  sci.physics.fusion periodically.  (Please note that not 
  all sections are completed yet.)  Because the FAQ is quite
  large, most sections are posted only every three months, to avoid
  unnecessary consumption of bandwidth.
  All sections of the FAQ which are ready for "official" 
  distribution are posted to sci.physics.fusion, sci.answers, 
  and news.answers, so you can get them from these groups by 
  waiting long enough. 
* 2) World-Wide-Web (Mosaic, Netscape, Lynx, etc.):
   Several Web versions now exist.
   The "official" one is currently at
     
   We hope to have a version on the actual PPPL Web server 
      () soon.
   There are other sites which have made "unofficial" Web versions 
   from the newsgroup postings.  I haven't hunted all of these down 
   yet, but I know a major one is at this address:
 
 Note that the "official" one will include a number of features
 which cannot be found on the "unofficial" ones created by
 automated software from the newsgroup postings.  In particular
 we hope to have links through the outline directly to questions,
 and between vocabulary words and their entries in the Glossary, 
 so that readers unfamiliar with the terminology can get help fast.
 (Special acknowledgements to John Wright at PPPL, who is handling
  much of the WWW development.)
* 3) FAQ Archives at FTP Sites (Anonymous FTP) - Intro
  All completed sections can also be obtained by anonymous FTP 
  from various FAQ archive sites, such as rtfm.mit.edu.  The

  Please note that sections which are listed above as having
  multiple parts (such as the glossary, and section 2) are 
  stored in subdirectories, where each part has its own
  filename; e.g., /fusion-faq/glossary/part0-intro. 
  Please note also that there are other locations in the rtfm
  filespace where fusion FAQ files are stored, but the reference
  given above is the easiest to use.
  There are a large number of additional FAQ archive sites,
  many of which carry the fusion FAQ.  These are listed below.

   If you do not have direct access by WWW or FTP, the 
   rtfm.mit.edu site supports "ftp by mail": send a message 
   to mail-server@rtfm.mit.edu with the following 3 lines
   in it (cut-and-paste if you like): 
send usenet-by-group/sci.answers/fusion-faq/section0-intro/part1-overview
send usenet-by-group/sci.answers/fusion-faq/section0-intro/part2-outline
quit
   The mail server will send these two introductory 
   files to you.  You can then use the outline (part2)
   to determine which files you want.  You can receive
   any or all of the remaining files by sending another
   message with the same general format, if you substitute
   the file archive names you wish to receive, in place of the 
   part "fusion-faq/section0-intro/part1-overview", etc. used above.
* 6) Additional Note / Disclaimer: 
  Not all sections of the FAQ have been written
  yet, nor have they all been "officially" posted.
  Thus, you may not find what you're looking for right away.
  Sections which are still being drafted are only
  posted to sci.physics.fusion.  If there's a section 
  you can't find, send me email and I'll let you know 
  what's up with it.

*** D. Status of the Conventional Fusion FAQ Project
-----------------------------------------------------------------------
* 1) Written FAQ Sections:
  Most sections have been at least drafted, but many sections are still
  being written.  Sections 2.3, 2.4, 2.5, 3.1, 3.2, 3.3, 4.1, 4.2, and 9
  remain to be completed.
  Those sections which have been written could use revising and improving.
  I am trying to obtain more information, especially on devices and 
  confinement approaches; I'm also looking for more information on 
  international fusion research, especially in Japan & Russia.
   *** I'd love any help you might be able to provide!! ***
* 2) Building a Web Version
  A "primitive" version (which has all the posted data, but isn't
  especially aesthetic) exists now.  Would like to add graphics and 
  cross-references to the Glossary, between FAQ sections, and 
  to other internet resources (like laboratory Web pages).  
* 3) Nuts & Bolts - 
  I'm looking for ways to enhance the distribution of the FAQ, and
  to get additional volunteer help for maintenance and updates.
  We are in the process of switching to automated posting via the 
  rtfm.mit.edu faq posting daemon.
* 4) Status of the Glossary:
 # Contains roughly 1000 entries, including acronyms, math terms, jargon, etc.
 # Just finished incorporating terms from the "Glossary of Fusion Energy"
   published in 1985 by the Dept. of Energy's Office of Scientific and
   Technical Information.
 # Also working to improve technical quality of entries (more formal.)
 # World Wide Web version exists, hope to cross-reference to FAQ.
 # Hope to have the Glossary "officially" added to PPPL Web pages.
 # Hope to distribute to students, policymakers, journalists, 
   scientists, i.e., to anyone who needs a quick reference to figure out 
   what we're really trying to say, or to decipher all the "alphabet 
   soup."  Scientists need to remember that not everyone knows those 
   "trivial" words we use every day.  The glossary and FAQ should be 
   useful in preparing for talks to lay audiences.  Students will 
   also find it useful to be able to look up unfamiliar technical jargon.

   As I recall, you didn't hesitate to rewrite my posts when you found
yourself in some tight spots.  So I'd stay away from any conversations
on ethics, if I were you  -- then again, maybe you're not troubled by
hypocricy.  I wouldn't know.
   Anyway, Russell, Michael, Jeff and others claimed that my point was
obvious,  called it a cliche, dismissed it as  trivial, etc. -- curiously,
that didn't stop them from disputing it or calling me all sorts of names.
   I don't offhand remember you calling it obvious, but you certainly
agreed with it -- at least three separate times.  Yet for some reason
you keep changing your mind.  I think you ought to figure out what you
believe and get back to me after you have it sorted out.  This is getting
silly.

   They're easily comprehensible.  The question is, what makes you think

not properly following your "rule of science"?  Or do you believe you're

   That's an interpretation, although hardly worth the name.  As I've
already pointed out,  "action-at-a-distance" is an explanation of the
workings of the remote control (albeit an empty one).  I ask, "Mati,
how does the remote work?"  You tell me, "It exerts a force."  I say,
"Mysterious forces -- yeah, right.   O.k., how do _they_ work?  You
answer,  "Action-at-a-distance,"  and I reply, "You sound more like

   Again, your self-evaluation has no relevance here.  And I see you
accept my point, since  you're now claiming to have a philosophy
that's superior to any philosopher's, while before you argued that
physics was ruled by evidence, not "philosophical ideas."

   You're being duplicitous again.  You cited the religious motivations of
Maupertois or Fermat  (you weren't sure which) in order to deny that
mysticism had a meaningful relationship with physics.  You did poorly.
Not only were you uncertain who you were actually talking about, you

physicists.

The Moran (tm)  is, as far as I can determine, an anti-Semite engaged in

Imho,

except what is described in evolution itself.  Evolution boils down to 
many other theories that all boil down to a premise that can't be

I wrote to the author of the article, Paul Kwiat. He was kind enough
to describe a very clever method for dramatically raising the 
probability of having a single photon present in the test. It involves
a parametric conversion via an ultraviolet fluorescence interaction.
This interaction creates a pair of lower frequency photons, one of 
which is detected by a trigger.  At this point you can safely assume
that the other is in the apparatus.
A very nice trick!

  I'm not quite sure what you're getting at.  As others have pointed
out, the space shuttle bay in your example is not an inertial frame.
  Are you trying to show how gravity affects things?  If so, then a
better example would be something like an elevator in free fall, i.e.
a frame in which accleration exactly cancels out the effects of
gravity.  But in this case, you do have a (local) inertial frame -- it
would pass all the tests.  The presence of gravity may screw up your
transformations (i.e. how to describe one reference frame in terms of
another), but it would not affect the existence of inertial frames.
In fact, GR is constructed using the existence of (local) Newtonian
inertial frames as one of its starting points.

What I have seen is an unsupported assertion that a) you
understand Newtonian mechanics with recourse to mathe-
matical machinery, b) that you 'understand' the machinery,
specifically, calculus, and c) that 'understanding' calculus
did not significantly improve your understanding of Newt-
onian mechanics.
Your refusal to demonstrate such on the grounds that I am
engaging in a 'domination ritual' (whatever that means; more
in a moment in re this and other misuse of terminology) is
an argument that has neither force nor merit; I assure you
that I am not intending my objections as such, but let us
assume for the moment that you are spot on.  Does this negate
in any way your rhetorical (the burden of proof is always
upon the one who advances the proposition) or logical obli-
gations?  Of course not.
Allow me to demonstrate with a small fable:  suppose I am a
nineteenth century archeologist who for purely personal
grubby reasons despises a professional colleague and who wishes
to humiliate him via the agency of destroying his professional
reputation.  Now, I know that he has built it through a series
of ingenious proofs that the lost city of Troy is a construct
of myth, and so in my malice I deliberately set out to find
and unearth this supposedly fabulous city . . . which I suc-
ceed in doing.  Can my rival, who we may suppose knows my
desires, cry foul, remonstrate with his fellows to ignore the
overwhelming evidence that Troy exists, purely on the basis
of the pettiness of the motivations which caused it to be
found?  Of course not - the city exists irrespective of the
ambitions of the discoverer.
And that is the position you find yourself in now - your
characterization of my motivations, true or not, in no
way excuses you from demonstrating the validity of your
claims.
Quite frankly, I think you're well aware of the weakness of
your position and I find the manner in which you choose to
defend it disgusting.  You have absolutely no proof to back
up your feeble attempt at character assassination, nor can
even _define_ what you mean by 'academic procedures of dom-
ination,' rather lazily preferring to believe the pejorative
denotations invoked by that murky phrase are enough to deflect
my entirely legitimate request for validation of your claims.
In fact, you seem to specialize in muddying, rather than
clarifying definitions.  For example, in answer to my initial
post you claimed:
----begin----
Intuition doesn't explain things; explanation is a textual
or rhetorical act.
----end----
but in a later post went on to say:
----begin----
Let's suppose, however, we want to teach a child how the Moon
moves around the Earth.  We find an apple tree out in the
fields of England, and there's conveniently a pale moon hanging
in the late afternoon sky.  There are several apples scattered
on the ground.  We pick one up and encourage the child to notice
that, in certain positions, the shadow on the apple is similar
to the shadow on the moon.  Now we throw the apple a short
distance.  It moves in a curve and strikes the ground.  Then
we throw another one a bit harder, and of course it strikes the
ground further out.  Now, the child knows that the Earth is a
ball; so when we ask her what would happen if we could throw the
apples as hard as we wanted, and kept throwing them harder and
harder, she will correctly guess that eventually one will either
circle the earth or fly off into space . . .
This child now intuits something about the motion of the Moon
around the Earth, which can be generalized to the whole Solar
System . . .
----end----
In one post, you are so bold as to say that intuition does not
explain things, yet less than a week later you follow up with
another to show that you clearly think it does; you're picking at
whim the definitions which best supports your arguments of the
moment, not even making the effort to check that they are
consistent.  This has been and always will be the mark of an
inept or dishonest argument.
Nor do you make any effort to spare more reputable sources than
yourself insult; already you have claimed that it is not well
known that Feynman is mediocre at best and that Scientific
American has been 'thoroughly discredited,' whatever that means
in your personal lexicon.  This too is a signature of sorts, the
hallmark of those reviled creatures collectively known as trolls,
the profile of which you fit remarkably well.
So much for the digression to personal motivations.  Now that
we've got all that off our chests, if you're really interested
in defending the thesis that one needs no knowledge of math-
ematics to understand Newtonian mechanics, would you please
present some evidence a) that you understand Newtonian mech-
anics without resort to mathematics (such as a nonmathematical
argument that explains why the cube of a satellites radius
is proportional to the square of its period), and b) that you
understand calculus.  If you can show a) and b) I'll take
your word that your b) didn't augment your a) :-)
Please be very sure that I am _not_ asking for any rigor, and
as proof of the bona fides of my intentions, I'll be more than
satisfied if someone else pronounces judgement on whether or
not you have demonstrated either of your above propositions.
>What proposition was it I was supposed to have advanced

You then went on to state that knowing elementary calculus in no
way informed your premathematical understanding of Newtonian mech-
anics.  I'm asking you to demonstrate the accuracy of your state-
ments, no more, no less, and personalities do not enter into this
request at all.

   In my home town there has to be a guy named Stefan who looks
exactly like me. He also wears the same type of clothes. I have never
seen him, but several people told me they saw me in a place I never
were. My best friend almost put a hand onto his shoulder before
noticing it was not me. What a pity he didn't speak to him. I'd like
to meet him. Sometimes his friends approach me like: 'Hi, Stefan, how
are you? I didn't know you wore glasses.'
   And now for the funny part. When somebody asks me for my name (in
the disco, in my taxi cab) and I don't want him/her to know, I used to
call me Stefan, and that was before I knew this guy existed. Gives you
headache.

How one copes is not the issue. The real issue is that in doing
science you are mostly required to restrict your attention to exactly
those sort of situations where, as you put it, `mostly one of them is
overwhelmingly more likely than the other'.
I hope you realise that there are many decisions which people have to
confront where such a qualification does not apply. And I would also
hope you realise that any scientist who refuses to make judgements in
any circumstances other than those where of all the available choices
`mostly one of them is overwhelmingly more likely than the other' -
such a scientist would, as a consequence, be intellectually and
morally inadequate.

Perfect example! Both are correct, but Copernicus is less complex, and
consequently preferred.

Of course, but that's not the issue right now.

I don't see how. But even if, for the sake of the argument, we assume
this possibility, the invariant time is orthogonal to SRT, i.e. it makes
no difference whether it exists or not, because SRT yields correct
predictions as it is.

Yes, and I will do that as long as it stands, i.e. as long as it is not
falsified.

Science progresses by falsifying theories, but as long as a theory gives
right predictions, and is not falsified, I don't see what's wrong with
accepting it.
On the other hand, if you have an equally 'strong' alternative, feel
free to believe it. Only, if it's equally strong, there will be no
conflict. The present discussion could be an indication that the
two viewpoints pro and contra are not equivalent.

Unfortunately, the limited circumstances are all we have. It is possible
to make all kinds of assumptions about what's outside, but we will never
know one way or the other. Discussing such assumptions might be a
comfortable passtime, but will always remain purely speculative.

All predictions of SRT have been correct so far. Nobody claims eventual
further predictions will all be correct. As long as this is so, why not
be content with a satisfactory theory?

Subject: Re: When will the U.S. finally go metric?
From: d005794c@dcfreenet.seflin.lib.fl.us (James Wentworth)
Date: 15 Nov 1996 23:14:19 GMT
This is a most interesting thread.  However, no one gave an answer to the 
question, "When will the U.S. finally go metric?"  My answer is, "never."
A more meaningful question would be, "Why should the U.S. go metric at 
all?"  There are no doubt many answers to this question, but my response 
would be that there is _no_ compelling reason for the U.S. to do so.  The 
global economy and interdependence arguments are mere bogies.  Up until 
about 1965, the U.S. was capable of manufacturing all of the goods 
needed/wanted by industry and the citizenry, respectively.  In other 
words, an American could purchase a toaster, radio, automobile, or 
anything else he/she needed that was designed and manufactured in the 
U.S. using domestic labor and materials.  I don't know what the U.S. 
population was in 1965, but it certainly provided a large enough market 
to sustain our industry.  Our population is considerably larger today, so 
it would surely provide a more than adequate market for U.S. goods and 
services.  The fact that this is not the case today is due to corporate 
greed and greed and shortsighted thinking on the part of politicians.
If we wished, we could once again be a self-contained economy and 
society.  The backlash against NAFTA and GATT are the first signs of our 
possible return to our former economic state of affairs.  In such a 
situation, we can and will use whatever system of weights and measures we 
choose with impunity.  If other nations don't like it, so be it.
However, there is a more immediate reason the U.S. shouldn't go metric.  
Why should we use an inherently inferior measurement system?  The 
American Standards Association (ASA) units are more practical than their 
metri
