Poynting vector. Arithmetic mistake28 Feb 2006 22:04 GMT26
It was found that many physicists did not know how to calculate the
Poynting vector. According to Jackson [1] (6.132), a time-average flux
of energy in the z-direction given by the z-component of the real part
of the complex Poynting vector S = (E x B*)/2. But authors of [2 - 6]

Looking for good references on aether models for Maxwell's equations24 Feb 2006 09:12 GMT24
It seems that both Fitzgerald and Reynolds had constructed
mechanical models that describe Maxwell's equations.
It seems that these models where based on a large
number of tiny spheres connected by rubber
Journal of Mathematical Physics and the field theory.24 Feb 2006 07:40 GMT1
I sent five papers to JMP and concluded that editors of the journal are
incompetent to face problems of the field theory.
In a paper "Defects of the general field theory" (05-1075, January 4,
2006 9:17 PM) I show that the standard classical electrodynamics does

Contradiction inside of the electrodynamics22 Feb 2006 19:25 GMT7
I considered absorption of a circularly polarized light beam in a
dielectric in the frame of the standard electrodynamics. I calculated
energy, momentum, and angular momentum that were carried by the beam
and that were absorbed in the dielectric. The energy and momentum were

Moving Dimensions Theory Explains Away Einstein's Block Universe, Accounts for Action At A Distance, Unifies GR & SR With QM, and Renders String Theory Unnecessary http://physicsmathforums.com20 Feb 2006 01:54 GMT7

Hello All,
Please respect that Moving Dimensions Theory is just a theory.
I look forward to feedback and insights regarding its logic.

The Inmates ($tring Theorist$) Are Running The Asylum
$tring theory has done far more damage to physics than just $tring
theory itself.

Generation of Large Electrostatic field18 Feb 2006 16:21 GMT14
I'm trying to figure out a simple way in which to create a large,
static electric field (at least 10^4 V/m, if not 10^5 or even higher)
over a short distance (about, or less than, 1cm). Could I simply hook
some high voltage source up to a parallel plate type configuration and
