Physics versus Mathematics (or, Physicists versus Mathematicians)
|
| |
I have not had any time for physics recently and expect this unfortunate state of affairs will persist for awhile longer, but I did want to bring forth a recent "behind the scenes" discussion between one individual poster, and the moderators. That individual made the statement, which which I could not agree more, that:... more »

'Three-Dimensional-String' Theory
|
| |
The 0-dimensional 'building block' , point, theory of the Standard Model has had problems. And the 1-dimensional 'building block' String Theory also seems to have challenges. Has anyone attempted a 3-dimensional 'building block' String Theory? That is, a theory in which the elemental, extended object, String, is 3-dimensional instead of 1-dimensional.... more »

The Principle of Relativity: Invariance and Covariance (Barut 1964, I.6)
|
| |
I have found the following sentences in A. O. Barut, Electrodynamics and Classical Theory of Fields and Particles, New York: MacMillan 1964, which may be helpful for clarifying the relationship between the form of an equation and its relativistic (non-)invariance. "As a generalization of ordinary vector calculus (which expresses the fact... more »

theory of "superpoints"
|
| |
Hi I would like to present an idea of space structure. It's a draght now not a full theory I understand but maybe someone who is an expert could look at the idea. It's 20 p long. I would like to ask somebody who is an expert to look at it and say an opinion. I believe it can be interestring. I chose three chapters that would give a look at the basics.... more »
