A. Length of arrows is constant. cos^2+sin^2 = 1. Energy is conserved.
It flips from moving mass to compressed/stretched spring and back again,
from E-field to B-field and back again.

S. There is no energy to conserve 'till you intercept the wave
with some matter. The structure of that matter will determine the
near-field E/H ratios. AE didn't mention, (or didn't know) that his
moving *observers* have an aperture of about 1/2 wavelength.

S.Nope. This way:

A. Definitely and emphatically NOT. Energy zero, created from nothing?
Sorry, you can NOT have a null B-field and a null E-field at the same
time, which is what that diagram shows.

S. It happens on the far end of any dipole and you can measure it
with a single terminal ammeter.

A. Where's the spring?  Where's the moving mass? If the spring is not
stretched or compressed, how is it going to reverse the momentum of the
mass?

S. The electron mass and the Coulomb force are the spring and mass.

A. Aether was the "spring" and "mass" of the old clockwork models that
Maxwell thought in terms of, and a very bad analogy. Nor can you have
fairy dust to make it work either. What works for sound doesn't work for
light or radio, they are different
models even though both are sine waves.

S. Indeed. JC Maxwell did seem to think in those terms but you
might look at some of his discussion with Weber and find he had
little if any concept of electrons. He could only model a fluid
like medium.

The wave is sinuosoidal usually because a mass is oscillating at
resonance. That is not always the case in many EM structures.
(They aren't very efficient tho )

S. Look at Two Dimensional Waves and Radiation Pattern of a Quarter Wave
Antenna (interactive) and you can imagine why the CP is hard to
illustrate for both E and H planes.

A. READ CAREFULLY and acknowledge:
Look, all I want is for you to accept is a 90 degree phase shift between
the E and B fields.

S. No... you are misinterpreting the illustration with the spiral
arrows.
A.
That's all that is necessary and sufficent, you can
have all the other diagrams, I'm not arguing about them.

S. Are you sure H plane energy is even necessary?
(I think one of Tesla's MisExperiments tried
to show something like this but AFAIK he didn't actually
balance out the return currents.

A. Once you do,
the complex plane with "real" and "imaginary" numbers becomes a simple
way to describe AC electrodynamics.

S. Simple is not always correct.

A. Math is a tool, that's all. It's
shorthand. I've assisted in building analogue computers for Concorde
with it, and they worked for 30 years. All that is required is that we
speak the same language.
If you can just accept that the old money that sends kids to MIT and
Princeton
are not the best brains in the world of physics... Didn't GW Bush go to
MIT?
Nah...Yale. same difference, old money. Is he an engineer physicist? Is
he even a lowly can't do anything physicist like Roberts or Andersen? Of
course not. He's a loud mouth.

S. LOL

AFAIK the magentic and electric force has be quite sucessfully
unified, without use of magnetic monopoles or luminerous corpuscles
hurtling through space. What you are tying to do is UN-unifiy them
so you can expolit effects that never existed anyway except semantically.

Compton effect: Matter interacting with light is going to adjust
the speed of the light to c wrt the interacting matter.

The mass and tension of the interacting charges establish c.
Weber observed that on the surface of a wire.
