acceleration of universe19 Apr 2004 09:41 GMT1
If the universe were divided into two mass zones, and one zone
repelled the other,supernovae would not only accelerate away from us
but the zone in which we are living would accelerate away from the
supernovae.Also cosmic rays could be repelled by one zone and pushed
Projected Newtonian Orbit18 Apr 2004 20:32 GMT2
A particle P goes around a focus F of an elliptic orbit E in a plane
EL where FP sweeps out equal areas in equal time intervals.This motion
is projected  onto another plane ELP arbitrarily inclined to EL as
from another observer's viewpoint. The projected particle PP now
The Right Angle Lever Paradox17 Apr 2004 15:29 GMT2
The Right Angle Lever Paradox
    The "Right Angle Lever Paradox" is a classic construct which is taught in
most courses in Special Relativity. As with all paradoxes, it reveals that and
error has been made in our thinking. It may be interesting then to examine this
Basic question on quantum field theory15 Apr 2004 16:50 GMT5
I studied undergraduate physics years ago, so I have an advanced
question for which I am seeking a relatively simple answer.  Hope
someone can help.  I always have wondered how it is, mathematically,
that quantum field theory can unify waves and particles.
Superconductivity from AnisotropicTunnelling?14 Apr 2004 22:16 GMT1
Current flow causes field vortices that impede flow, aka resistance.
But technically speaking, quantum tunnelling doesn't amount to actual
flow of electrons, and no work is required for tunnelling. So can
tunnelling be used to transport electrons in a series of small jumps,
A Look at Quantum "Spookiness"14 Apr 2004 21:34 GMT1
A Look at Quantum "Spookiness"
    The results of quantum theory were described as "spooky" by Drs. Einstein,
Podalsky, and Rosen because quantum theory seemed to reject "objective
reality". They believed that all observed effects must be produced by "local"
Electron Given Planetary Orbit - Vacuum Resonance?13 Apr 2004 17:10 GMT1
What could be done with an invention like this:
http://focus.aps.org/story/v13/st15
Could this be turned into the world's smallest gyroscope? Hmm,
probably too short-lived.
transforming matter to antimatter?12 Apr 2004 15:58 GMT3
according to feynman diagram, antimatter is just matter running
backwards in time. so is it possible to transform matter into
anti-matter? even if this takes a great deal of energy, the
end-product should release a great deal of energy.
What are we really made of?10 Apr 2004 14:01 GMT5
I understand that most of our mass (3599/3600)comes from neutrons and
protons. I also understand that nucleons are made from up and down
quarks. I even understand that only a small percentage of the mass of
the nucleons come from the quarks, while the rest comes from the force
neutrinos and quantum field theory10 Apr 2004 13:30 GMT1
Could a neutron consist of a neutrino and electron orbiting a proton?
Presumably the neutrino would have to affect the electric or
gravitational field so much that the electron would orbit very close
to the proton compared to what it does in the hydrogen atom.
open questions in physics-The Big Question10 Apr 2004 00:38 GMT1
The Big Question is not how to unite GR and QM ( though they might help
answer it) but this:
How do atoms become conscious?
Or What is consciousness?
particle spin and stability08 Apr 2004 22:57 GMT1
Can the stability of a spinning bullet in any way be compared to the
spin of
an orbiting electron -i.e does an electron have some sort of
trajectory which its relativistic spin keeps stable?
Zero Point Energy08 Apr 2004 05:46 GMT2
I want to know if any body has heard or read about condensed charged technology.
if any body has please send me a copy of it on to my email.
it has got something to do with zero point energy.

determination of quark mass06 Apr 2004 18:48 GMT4
EQUATION THAT PREDICTS PARTICLE REST MASSES
The following equation generates the masses, in Gev, associated with
the six quarks:
Down, up, strange, charm, bottom, top and predicts the masses of two
More QM/Dirac Nonsense01 Apr 2004 18:46 GMT1
I was reading Dirac's famous text "The Principles of Quantum Mechanics," 4th
edition, and I ran across something that I simply can't believe QM devotees
can accept as physically true. On p. 262, Dirac makes the statement: "the
theoretical velocity in the above conclusion is the ...
