Around an isolated charge, there is no force and so no force field.
Electric field is a mathematical concept, evolved for the ease of
calculations. But E field is fictitious.
                  Since E is a representative of charge, every effect

POSTULATES OF A MODIFIED CLASSICAL PHYSICS
Inertia law:
Mass is a scalar velocity field:
Scalar form: m(v) = m0 + int(0,v) (dm/dv) . dv

I am studying superconductivity. If the beginner whom the foundation
can teach also has the book of intelligible superconductivity, please
let me know.
A homepage is sufficient.

It was pointed out in the article (10) that the electrons moving with
a steady drift velocity in the conductor A do not notice the presence
of the charge in the conductor B, with zero current and placed
parallel to it. There is no reason to believe that the situation of

I am doing a research project and a portion of it involves magnetic fields,
which
I have very little experience in.
I need to find analytical techniques for calculating the actuation force

Following paradox was included in my last message, but a poster
advised me to post it separately. He also told me that Dirk Van de
moortel is expert in pin-pointing errors in such things, therefore he
is specially invited.

I'm newbie here, so please excuse... generally my English
From the very beginnig:
I'm trying create the model of energy levels in fiber ZBLAN:Ho3+.
My model is almost done, but I want to do special case:

There is a special spot in my house where, if a person stands, seven
feet away the radio picks up a formerly static-filled station very
clearly.  Are the radio waves diffracting around the person's body and
converging on the antenna?

The electric field of a moving point particle (point current) is given
by (Lienard-Wiechert form, gaussian units):
E = q*((n-v/c)*(1-(|v|/c)^2)/(s^3*R^2) + n x ((n-v/c) x
(dv/dt)/c)/(c*s^3*r^2))

Here's the problem:
Nearshore processes research (e.g., sediment transport, coastal erosion)
is in desperate need of a new method for measuring the bathymetry of
the surf zone during storms.   Vessel-borne methods, which generally

I did not see this reply to my article before, and I am sorry it has
taken me this long time to further comment.

Bill Bryson's best-selling science book
"A Short History of Nearly Everything" is very well written.
An informative review of the book can be found at

In the threads of my last article (10), relativity of two current
carrying conductors had been brilliantly expounded by Richard Perry.
I would like to rake up this subject again to discuss some logical
points.

Basically, after wearing the watches on my wrist or even in a pocket,
after a while (a few hours, I estimate,) the various watches stop
ticking.  When I stop wearing them, after a while, they start ticking
again.  I have tried numerous watches and replaced their batteries for

I considered absorption of a circularly polarized light beam without
an azimuthal phase structure in a dielectric in the frame of the
classical electrodynamics. I calculate transferring of angular
momentum and energy to the dielectric. My result differs from the
