Question on Berry Phase19 Jul 2009 20:57 GMT6
(This is a revised version of a question posted in 2008.)
I have a question on Berry phase for this simple example:
Define D as the 4X4 diagonal 0-1 matrix
[1000]
The Original Conception of Spin Foams19 Jul 2009 12:16 GMT1
I did some work in 1993 with the help of Arkady Kheyfets and Warner
Miller on a concepion that would be given the name "Spin Foam" a few
years later, the connection of spin networks into paths in a
generalized superspace. The work was based on the work of Panzano and
Deriving Maxwell's equations, the Lorentz force law, and the regularised perturbation expansion from the minimal interaction in qed15 Jul 2009 07:13 GMT3
In http:/papers.rqgravity.net/RQGFoundations.pdf I showed how quantum
mechanics can be formulated as a theory of particles. I use this
formulation to construct qed in

Another look at Newtonian potential10 Jul 2009 08:11 GMT5
Can an alternative measure of Newtonian potential
energy remove the Schwarzschild singularity
(or at least move it to r=0)?
A shell of matter gives rise to a potential which
Physical example for Maxwell-Boltzmann statistics09 Jul 2009 16:50 GMT12
Maxwell-Boltzmann (MB) statistics applies to _ordered_ sets of
distinguishable things. Consider 2 coins and the 4 cases (H = head, N
= number)

Strong Force08 Jul 2009 15:30 GMT1
Hi again.
When I was a young student, I thought that I had a reasonably solid
understanding of what the strong force (aka strong nuclear force) was,
namely, the force that holds nuclei together against the
Electromagnetic equivalent to a black hole08 Jul 2009 07:07 GMT6
Is there any concept in standard physics of an electromagnetic
equivalent to a black hole?
I observe that in a hydrogen atom the electromagnetic force is ~10^40
stronger than the gravitational force. Also, a proton is ~10^40 too
Explaining Schroedinger's equation06 Jul 2009 22:46 GMT29
The well known problems of interpretation of quantum mechanics mean that
physical law lacks a physical basis. I have revised my approach to this
problem and would appreciate the comments of readers.

Primordial Nucleon Synthesis and the next 17 ? minutes05 Jul 2009 20:21 GMT24
I have just been boning up on primordial nucleosynthesis, and the
following statement in Wiki (admittedly not always the most reliable
source),  struck me as incredible:-
"there are about seven protons for every neutron at the beginning of
ATOMIC SIMULATION04 Jul 2009 20:37 GMT4
Is there any research going on the simulation of atoms.
like collisions of two or more atoms of any kind .(not in reality but
on computers)
are there any softwares available for such tasks ?
An explanation of the origin of inertia of a body03 Jul 2009 21:12 GMT6
Inertia is the tendency of a body to resist being accelerated or
decelerated. An accelerated charged particle creates an electrodynamic
field proportional to and in the opposite direction of the acceleration.
The inertia of a particle is explained by considering the electrodynamic

The Classical and/or Non-Relativistic Form of the Haag & Leutweiler02 Jul 2009 03:06 GMT5
The Haag theorem is established within the setting of axiomatic
quantum field theory. Historically, it arose from the consideration of
the relation between vacuum polarization and interacting fields and
the earliest proofs were cast firmly in the language of quantum theory
