No.  The limit v/c << 1 is a mathematically rigorous, well-defined

This might be _Powers of Ten_, which was both a book and a short film
showed at science museums; IIRC, though, that started at a human scale,
showing people eating in a park, moved outward by powers of ten, and
finally moved back in again, ending with a proton, I think.
I don't recall the author, since it's probably been a decade since I saw
the book, but you should be able to find it from the title.

Or, the uranium in the soil of your back yard (say, 1000 m^2 x 10 cm x
2 g/cc x 3 ppm U = 600 grams.)
If this bothers you, uranium can be extracted from soil by heap
leaching with sodium carbonate/bicarbonate solution.  They're
planning to do this around the Fernald plant in Ohio, where soil
concentrations in some places are high enough to interfere with plant
growth.

You seem to be laboring under a tiresome presumption that "dumping
like a bag of goat dung" is an intellectually respectable way of
"demystifying" a philosophical argument.  You claim that most 20th
century philosophers are skeptical about personal identity?  Would
you care to conduct an opinion poll?  And while you are at it, would
you care to guess at the standing of postmodern "scholarship" in the
philosophy departments worldwide?

Actually, reading books is one of my favorite pastimes.  What I was
berating you for was an attempt to substitute name-dropping for
dialectics.  As long as you pull your own weight in this discussion,
I will be grateful for any apposite references that you might supply.
As regards the Meditations, I am by far my favorite secondary source.
And instead of a mere transcription, I have so far generously given
you two interpretations of Cartesian arguments.  Let's stick to the
issues at hand.

Once again, this approach is inadequate.  Descartes explicitly states
in his replies to the Objections that "when we become aware that we
are thinking things, this is a primary notion not derived from any
syllogism" (AT VII 140).  Hence to divide the cogito into premisses
and conclusion is inconsistent with its author's account of its
nature.

Has there ever been empirical evidence of mass, or energy, or force,
or spacetime, or the continuum, or any other ahistorical Platonic
universal?  Certainly there has.  The manifest success of scientific
theories that intimately depend on these explanatory concepts is
evidence enough to sustain the inference of their existence.  Can you
conceive of any empirical evidence to the contrary?  I doubt it.
As regards the naivety of totalizing, consider applying your epithets at
home.  What have Gorgias or Heidegger or Derrida given us to compare with
the legacy of Aristotle and Galileo and Descartes and Einstein?  And what
could be more naively, corrosively totalizing than consistent skepticism?

Please explain the process of man-made abstraction.  Wherein consists

Your trend meter is badly in need of calibration.  Strangely enough,
metahistory no longer enjoys the status it had a decade ago.  Blame
it on the fall of the Evil Empire or on the pernicious influence of
Hollywood, but academics are churning out narrative history as they
have not done since the heyday of Michelet and Ranke.  To take one
example, Maurice Lever recently sold his grand biography of Sade to
the studios for over a million dollars.  Does Hayden White stand a
chance of getting a quarter for the movie rights to the _Tropics of
Discourse_?  Face it -- the writings of your ideological brethren
exhibit all the vivacity and charisma of Bob Dole on triple Valium.
In any event, mathematics is of paramount importance to anyone
wishing to understand Platonism.  And I am told that purporting to
refute something you cannot understand is an egregious breach of
etiquette.

Nowhere in particular - the same place as mass or charge or number.
The history of the universals controversy is evidence enough of its
resilience to sophomoric taunts of this sort.

Since the child might as well have asked me for a unicorn or a round
square, the object of his desire is not identifiable with any actual
or even possible concrete particular.  (Though this point is commonly
credited to Brentano, its locus classicus is in the Sophist around
242d.)  To account adequately for the discussion of wants and needs,
universals are indispensable.  Note also that mute or unarticulated
strivings rule out the possibility of reducing these universals to
their verbal expression and vitiate Derrida's charge that "en
dernière instance, la différence entre le signifié et le
signifiant _n'est rien_".  Besides, the argument works just as well
with a proper name of a particular puppy as it does with the common
name of the young canis familiaris.

Actually, it turns out that if your explanation of signification is
to incorporate the logical standard of demonstrative reasoning, its
restriction to signifiers cannot be sustained.  The reason for that
is that any sort of proof theory depends on a criterion of type-
identity between sign-tokens, which cannot be a particular by
definition.  This point came to be recognized in the wake of failure
of the Quine-Goodman program of constructive nominalism in the early
Forties.

You are being silly again.  If meaning is a signifier[-token] that
hasn't happened yet, you have posited a thing that doesn't exist.
That the world could come to an abrupt end after I produce but before

Not at all.  I am INFERRING their existence from their apparent
indispensability in psychological explanation.  If you want to argue
that mass is a social construct, the onus is on you to prove that
mechanical explanation can proceed on the basis of, and reduced to,
contingent and arbitrary social conventions.  Mutatis mutandis, the
same goes for wants and needs, sights and sounds, affects and
beliefs, and other cognitive, conative, and perceptual categories.
Besides, you are the one carrying on "what we are *given*, in the
empirical world."  Here is a newsflash: what we are given are not
"signifiers and mute objects", but the contents of thought and
perception, from whose deliverances the existence and presence of
material objects must be inferred.

Psychology is an inchoative discipline.  But the practice of inference
to the best explanation exemplified by the above is the very model of
scientific reasoning.  Newton took a collection of effects handed down
by Copernicus and Kepler, and inferred their source in the force of
gravity.  If you know of a better way to advance knowledge, please
share it.

I am not sure what you intended the anaphoric pronoun to stand for.
My claim is that the existence of mental states is equally well
certified by observing human behavior as the existence of electrical
activities by direct measurement.  In each case the underlying cause
is inferred by abduction.  In each case this inference is
indispensable for further explanation.

We posit any number of entities on the basis of observation.  My
latest practical posit is that of one Brian Artese, a rational animal
to whom I impute the ability to grasp the meaning of the theses you
are advancing.  Am I jumping to conclusions?  You tell me.

This claim, found in Kant's First Critique, is as far as I can tell
not grounded in reason or experience.  As far as reason is concerned,
the order of temporal succession makes no difference in the validity
of an argument.  As far as empirical data goes, there is plenty of
evidence that the textual units of expressed meaning can be more or
less arbitrarily expanded or constricted according to the receiver's
cognitive and perceptual abilities, as happens e.g. during speed
reading.  So neither the order of signifiers nor their succession
appear to be germane to comprehension.

I do write more carefully; try reading on the same level.  I meant the 
faculty of understanding that is not essentially temporal.  The key point 
here is that your implicit presupposition of essential dependence requires
proof, since the logical content of understanding is not so dependent.

I am telling you that your profession of faith is logically inconsistent 
with belief in a standard of truth.  If you are incapable of telling the 
difference between logic and religion, so much the worse for you.

It seems reasonable to assume that material gratification would
supplant truth-telling in those who implicitly or explicitly reject
the possibility of aiming at telling the truth.  One of the things
that came out most clearly in the Sokal controversy is the concern of
the social constructionists for their shrinking budgets.

Padding and inflation implies superfluity.  I welcome any suggestions

  OK.  You may or may not have a point.  Let's say, for the sake of
argument, that what you say is true and that accelerations makes a
difference.  It seems to me that what we have here is two
accelerations and two decelerations.  If accelerations matter as you
say, aren't they evenly canceled by the equal and opposite
decelerations.  That seems symmetrical to me.  Why do we still have a
time dilation.  BTW I've seen nothing in the math that says that time
dilation is velocity dependent.  Speed yes.  Velocity no.  The dreaded
"absolutivity" keeps on creeping in.  :-)
  The most sensible solution to this conundrum that I can see is that
the earth-bound twin is moving *absolutely* much slower than the
absolute speed of light than the traveling twin.  OK.  Calm down now,
guys and gals.  :-)  It's just a partially baked idea I've been
thinking about recently.  I haven't thought it through completely.
I'm working on it.  Be cool.

Hi Jeff. I'm a little confused here... Are you working in the ring of
formal power series (R[[x]]) or is y some function of x? Apparently the
latter, but then something would appear to be missing from your
commentary. You might tighten up terminology around ``looks very close
to x=0'', too -- sounds a bit subjective when you put it like that.
I can't really address the point you were trying to establish, because I

I stated this badly. What I meant, and should have said, is the trivial 
statement that in the laboratory frame, in which it is most convenient to do 
the analysis, there is, obviously, no Coriolis force on the light. In the 
laboratory frame the light propagates rectilinearly between reflections by the 
mirrors that guide the light’s path and move with the disk. Under these 
circumstances the light’s interaction with the rotating disk consists in the 
light’s reflection from the mirrors. This can be considered an impulsive 
interaction-the light reflecting off of moving mirrors whose instantaneous 
velocities in the laboratory frame are determined by the rotational speed of 
the disk and their instantaneous positions on that disk. The reflection of 
light off of moving mirrors is well-understood. One can calculate the path of 
the light around the disk as a function of the disk’s angular velocity 
entirely in the laboratory frame of reference. One doesn’t need even to think 
about Coriolis acceleration.
Of course one could attempt the calculation in the rotating frame of reference 
of the disk. In that frame of reference one must consider the Coriolis 
acceleration of the light. In the rotating frame the light follows a curved 
path. Of course the analysis ultimately has to produce the same interference 
pattern as that based upon the laboratory frame. It might even be necessary if 
the light travels through some refractive medium which rotates with the disk 
rather than through vacuum, to do the calculation primarily in the comoving 
frame.

Even if it were necessary or desirable  to consider Coriolis accelerations in 
the rotating frame of reverence in the analysis, it would say nothing about 
the mass of the photon. The Coriolis acceleration is a purely kinematic effect 
relating the motion of objects in two different coordinate systems. The 
Coriolis acceleration does not depend upon the mass of the object being 
accelerated.
It is true that sometimes one needs to associate a Coriolis force with objects 
undergoing Coriolis acceleration in a rotating frame of reference. The 
Coriolis force is then defined as the product of the mass of the object and 
its Coriolis acceleration. This fictitious "force" is defined so that Newton’s 
second law of motion formally holds in the rotating frame of reference. 
When considering the motion of massless objects in a rotating frame of 
reference, however, (such as the motion of an abstract point) one can still 
speak of its Coriolis acceleration without reference to any corresponding 
Coriolis force. 
In looking at your post again, I think I see where your most serious 
misapprehension lies. You write above:
> >>As the effect is produced on all particles, photons, neutrons,
> >>electrons etc, and since it is mass that acceleration operates on, one
> >>questions the alleged zero rest mass of the photon.
The phrase, "since it is mass that acceleration operates on", is wrong. 
Acceleration is simply the second derivative of position with respect to time. 
It matters not what, if anything, has the position being differentiated. One 
can reasonably speak of the acceleration of the midpoint joining the earth and 
moon, although there is no mass associated with that point, although, if one 
cannot meaningfully associate a mass with that point, one cannot define a 
force acting upon it in accordance with Newton’s second law. 
In conclusion, even if it were useful or necessary to speak of a Coriolis 
acceleration of the light in analyzing the Sagnac effect, there would be no 
basis for introducing a Coriolis force unless it had been previously 
established that there was a mass to be associated with the light. 
(Your remarks on the Coriolis effect below are Okl. They are just irrelevant 
to the Sagnac effect.)

Maegan,
This is an interesting guestion.  There is a simple solution if you
attach the string overhead instead of attaching it to the ground.
You can plot all the (ideal) answers very simply.  
First drop the wooden ball straight down and record the location the it
gets to 
after a unit of time which is convenient. Now find the point halfway
between the 
origin and the result and using this point as your center, draw a circle
which crosses the upper point and the lower point. Stretch the string
from the
origin and try out different angles. For every angle of descent the ball
should 
just reach the line. You can figure out the acceleration from this. It
should
be possible to even come up with a formula.

Come on, Lloyd, VSEPR and VB theories are taught in the first semester

  Ken even though I agree with you that time dilation is a direct
consequence of making the speed of light constant mathematically, I
don't think that Einstein just decided to do that our of the blue.  I
would bet money that somehow Einstein got wind of the MM null result
before submitting his paper for review.  Does anyone here know whether
or not the SRT paper was submitted before of after the MM experiment?

  I tend to disagree here and side with Brian Jones that the measured
c is absolute.  [Am I stating your position correctly Brian? If not,
please correct me.]  I think the speed of light is the only absolute
value that can be measured, for the time being at least.  I think the
absolute (oops) speeds of ordinary particles are always less than c.
We are just having trouble finding a way to measure them.

  There is a slight problem with this logic.  Suppose you have a
standard inertial frame moving at an unspecified absolute speed.  I
understand that if you keep the same standard second you will get a
different calculated speed in another frame.  So far so good.  But
even if you always use the same standard second within your inertial
frame, how do you explain the fact that you always measure the speed
of light to be constant regardless of the direction of the beam of
light in the frame?  How does using the same standard clock explain
this weird result?  That's the question I should have asked.  I
realize now that using two frames is unnecessarily complicated for the
purpose at hand.  The question should have been:  What causes the
speed of light to be constant in the same "moving" frame in all
directions?

There is a theory running around that, in the early years of planet Earth, a 
Mars-sized object struck it, seriously rearranging the crust, mantle ,and 
even the core, and splashing a lot of mantle rock up into high orbit,  Thos 
rock eventually cooled and solidified into the Moon.  I've even seen video 
of a computer simulation of this.  Didn't get out of the gravity well, 
however.

Ionized is more likely; the solar wind is a plasma of H+, He+, and a few 
other ions and a lot of electrons.  These charged particles get into the 
magnetosphere and get trapped by the interactions of moving charges and 
magnetic field lines, bouncing from pole to pole like a reiterative Michael 
Palin until they get neutralized by interactions in the ionosphere and join 
thet atmosphere.

The real question we should be after is HOW life got started from non-living

I have a question (my first on this thread) related to tired light...
Special relativity correctly predicts the displacement of light passing 
through a gravity well.  Even if the photon - gravity interaction is totally 
elastic (all energy and momentum involved in the particles 'before' 
interaction can be found 'after' the interaction, with no frictional heating 
or other losses), the photon loses energy and momentum to the massive 
object.  Even in Newtonian physics, when there is an elastic interaction 
between two objects, there is transfer of momentum and energy between the 
objects, if they do not have exactly the same mass.  (This is a freshman 
physics problem.)  Since the photon must move at C, any loss of energy by a 
photon passing through a gravity well must be apparent as a change in 
wavelength (red-shift).  
Question:  How is the red shift due to transitions across gravity wells 
(presumably a roughly linear function of distance for intergalactic photons)
distinguishable from doppler red-shift?

Naw, screw that vector crap... That guy sounds like a nightmare physics

applied at 90degrees(Perpendicular) to the axis of rotation X distance
from axis. Torque only applies to rotation. Work can be applied to a
wheel turning, but you have to be very specific to get an accurate
result. But as you can see, they have the same dimensions, but when you
work with rotation, it saves you a lot of time if you use torque.
