On repeating Einstein's rotating disk experiment, I find redshift of rim = sqrt(1 - ^2) = sqrt(1 - ^2) = sqrt(1 - integraldr/^2) = sqrt(1 - 2delphi/c]^2) where w = angular...

By what, if any, methods other than by means of the Lienard-Wiechert potentials can the electric and magnetic fields of a moving point-like charge be derived? Any references...

A few simple questions: 1) Whats the exact value of Hydrogen line? 2) And under what condition(s) is this value holds true? Regards, Jay Bala.

The following takes up the December/January discussion from the thread ''EM field of photon''. Based on the details given in the entry S2g. Particle positions and the...

Schrödinger's Universe One of the very best books, that has recently come out, is Dr. Milo Wolff's brand new book: Schrödinger's Universe. I've just now finished reading...

Hi there, I am looking for any reference (article, textbook, etc.) that explains the transition from classical continuum mechanics to classical point mechanics (i.e....

In response to a fair amount of recent discussion about Foldy-Wouthuysen on sci.physics.foundations, someone suggested that a Wiki article be started on this topic because...

I once did a calculation for a NG, sci.military.moderated IIRC, concerning the lethality of the hypothetical weapon given a beam pulse energy comparable to the muzzle...

To all: With some good advice along the way from Nuropulp in some recent threads over at sci.physics.foundations, I have been studying Foldy-Wouthuysen transformations and...

In reading a paper I came across an expression that, while simple, I didn't really understand the interpretation of: out|A|in/out|in Where |in and |out are just two...

Hi folks After a long time of research and many e-mails to the powers that be a new version of the relativity FAQ "Does mass increase with speed?" was written and is now...

Adam is standing at the edge of a large disc rotating clockwise. Eve is suspended upside down on a large disc rotating counterclockwise. The relative velocity of the...

The twin paradox has been analyzed many times, and many answers are given. Dr. Parker has pointed to the multiplicity of the answers as proof of its underlying error. The...

Dear All, After several attempts, I finally succeeded to compare my proposal with the Lambda-CDM model. This essay can be downloaded at http://www.e-kr.org/ . Thank you...

I would like to consult in private with with young talented physicists on a variety of topics. Including, but not limited to: quantum electrodynamics, solid-state physics,...

I have noticed that Einstein stresses in various places that, whereas the speed/velocity of light is constant in SR, it is not in GR. The reason for my current source of...

If I take 3 playing cards and arrange them in front of my eye, so that a very small triangular aperture is created by the cards, and I adjust this aperture so that it is...

If two electrodes are sandwitching two dielectric materials with very different dielectric constants (but the same thickness), say, water and glass. Would the new dielectric...
