     For TIME HAS INERTIA readers  only

Dear Mr. Bhide,
  
I am responding to your very recent posting.

    It is easy to solidify  water vapor.  An ordinary refrigerator would
do the job.

    It is more complicated to solidify  Oxygen  or Nitrogen

    It would be much, much more difficult to solidify A SUNRAY.
    
THE SAME WAY THAT OXYGEN DOES NOT CONVERT BY ITSELF INTO  SOLID OXYGEN,
    
A SUNRAY DOES NOT CONVERT BY ITSELF INTO MASS.

  The machinery to convert a SUNRAY into a mass could be extremely 
complicated requiring temperatures near absolute zero and tremendous
amount of pressure.

    Like water vapor, Oxygen and Hydrogen, A SUNRAY  IS IN A RAREFIED 
STATE, HOWEVER, MUCH, MUCH MORE RAREFIED  that Water vapor, Oxygen  or
Hydrogen.
 
    This is my answer to your first question - and in order to avoid
ridicule, put-down, mockery  etc.,  I am posting it in  TIME HAS 
INERTIA  so that only some special people will read my reply.

    My answer to your second question, i.e.,

   "assuming that the universe consists of one Hydrogen atom and rest
    is space"

 
 According to my (A1) and (A3), The space will not tolerate the
 intruding Hydrogen atom and will DILUTE IT and emaciate it by
 means of its  TERMINATOR  agent  the  TIME , according to

              dE = -A E(t) dt

    I would like to hear your comments.  Please post in 
    subject:  TIME HAS INERTIA., otherwise I may miss reading
    your comments.     Sincerely,    Alexander ABIAN

The misunderstanding of E=mc^2 is one of the most common errors made 
on sci.physics.  Since energy by itself is not Lorentz-invariant,
E=mc^2 is only true in the rest frame of the particle.  In the rest frame
of the particle it has by definition no kinetic energy, just rest-mass energy.

The mass of a particle is lorentz-invariant, and is the same no matter how
it is measured.  You don't increase the mass of the iceberg by melting it.
Plus, whatever energy you add to the iceberg will be subtracted from the 
fuel supply of your bunsen burner.

In the case of electron and positron annihilating to form two photons,
here we have the case that mass is not conserved, but total energy is.

One of my mathematics professors once told me that the reason
there are Nobel prizes in mathematics, even though there are
prizes in physics, chemistry, etc, is that a mathematician had a
love affair with Alfred Nobel's wife.  He swore the story was
true.  It seemed unlikely to me at the time that a mathematician
would have a love life, much less an adulterous one, but I've
since realized they're human too.

My question is, what was the mathematician's name?  I vaguely
remember it being a multiple name.

My first posting was truncated.  Here's how it should have read.

In nightclubs I have recently seen light effects which apparently
use bright red, green, and blue lasers which are modulated with 
mirrors (I think) to do interesting things like project color 
images on a wall.  The red could be a simple He-Ne laser, but what 
about the green and the blue?  I know these light sources can be 
made with expensive and sophisticated lasers, but how could this 
be done as simply and inexpensively as possible?  Is it possible 
that these really weren't "lasers" and were instead some sort of 
collimated and color filtered bright light sources? 

I'm also curious how the light sources are modulated to get fairly
decent resolution at high refresh rates.  Just guessing, in one 
setup I would say the resolution was at least 100 x 100 on the wall,
maybe a lot better, with a refresh of around 60 Hz.  This may be 
implemented with a set of really fast stepper moters, but I'm not 
sure.  Anyone know how these tricks are done?  Thanks in advance.

It's important to remember that SR gives only the correct *kinematics*.
In order to determine the "conditions for mass-energy conversion," you
need a model for the *dynamics* of various relevent reactions, e.g.,
the Standard Model, which embodies all the conservation laws and 
allowed-reaction rates necceary to calculate how quickly (if at all)
matter and EM radiation can interconvert.

For example, why does a light beam not produce massive particles all the 
time?  It has nothing to do with SR (at least directly.)  One important
fact of life is that the subatomic particle spectrum is discrete and bounded
from below.  That is, for a light beam with photons less energetic than
1.012 MeV (twice the electon mass), there are simply no particles into
which the photons can convert.  But take an energetic (x-ray) laser beam
and shine it through some gas, and you will get plenty of electrons and
positrons produced by pair conversion.  (Kinematical restrictions, i.e.,
simultaneous conservation of energy and momentum, prevent this process
from happening in vacuo.)

Again (for those who didn't read my remark in the TIME HAS INERTIA
thread), the thing to do is get a moderated version of sci.physics
going.  I would even be willing to co-moderate such a newsgroup FOR A
LIMITED TIME, if certain worries of mine were quelled.  One, I would
need to be able to quit doing the job when I got sick of it, without
feeling guilty.  This would require the existence of someone willing to
pick up the slack, I suppose.  Two, I would need someone to hand me
whatever software was necessary, and have it work; I don't want to mess
around with software.  Three, I would need to be able to take vacations!
In short, my question is this: could I moderate or co-moderate such a
newsgroup without ruining my life?

There is not going to be moderation of sci.physics.  Nobody has
suggested that.

What has been suggested is that a new newsgroup be created, and that
this new newsgroup should be moderated.  People who prefer a more
uninhibited discussion can continue to read sci.physics.

Could you answer a question that I find to be utterly crucial here?  Is
this a matter of ingeniously evaluating well-defined expressions or is
there actually some freedom of choice involved?  In the
former case, even if ingenuity is required to do the integral, one is
essentially solving a well-posed *math* problem.  In the latter case,
one could imagine actual disagreement over the right answer - in which
case one is really adding extra fine print to the description of the
physical theory, not just calculating within a precisely specified theory.

I thought Feynman said this.  Anyway this doesn't mean it's going

Antimatter has positive mass; I can't remember if the 
experiments to test antimatter's gravitational acceleration by the 
Earth have yet succeeded, but if it had negative inertia it would
(for example) curve the other way than expected in a bubble chamber
in a magnetic field, not to mention that conservation of energy
and momentum in particle reactions would be totally different.

I recommend IDL software package. It's great for image processing.
I work at a petroleum laboratory, and use it alot with our cat-scan.

The software work on all unix platforms, MS Windows and Gameboy!!!

You can receive a free demo or a trial licence for 30 days.
A foating network licence (unix) cost $3000

The software is sold by Research Systems, Inc.

Email support@rsinc.com


Good luck!

The units of frequency are not Hz unless the original signals come
from the time domain.  The output of the DFT is often expressed
in cycles/sample, in which case the range is +- 0.5.
(0.5 c/s is also known as the Nyquist frequency).
For images viewed by humans frequency is also sometimes
expressed as cycles/picture width or cycles/degree of visual angle.
