| Question on Berry Phase | 19 Jul 2009 20:57 GMT | 6 |
(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 Foams | 19 Jul 2009 12:16 GMT | 1 |
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 qed | 15 Jul 2009 07:13 GMT | 3 |
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 http://papers.rqgravity.net/RQGQED.pdf

| Another look at Newtonian potential | 10 Jul 2009 08:11 GMT | 5 |
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 statistics | 09 Jul 2009 16:50 GMT | 12 |
Maxwell-Boltzmann (MB) statistics applies to _ordered_ sets of distinguishable things. Consider 2 coins and the 4 cases (H = head, N = number) case coin 1 coin 2

| Strong Force | 08 Jul 2009 15:30 GMT | 1 |
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 hole | 08 Jul 2009 07:07 GMT | 6 |
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 equation | 06 Jul 2009 22:46 GMT | 29 |
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. http:/papers.rqgravity.net/RQGFoundations.pdf

| Primordial Nucleon Synthesis and the next 17 ? minutes | 05 Jul 2009 20:21 GMT | 24 |
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 SIMULATION | 04 Jul 2009 20:37 GMT | 4 |
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 body | 03 Jul 2009 21:12 GMT | 6 |
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 & Leutweiler | 02 Jul 2009 03:06 GMT | 5 |
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
