Stalin had the science writers purge their texts of those qualities
that you miss and that we enjoy here in the west (they were condemned
as bourgeois inspired perversions with counter-revolution tendencies).
Hence you find decrepit pensioners sneering at elitist propaganda
(western science) that dismisses the party-approved water models of RF
transmission. In the historical perspective, we have to remember this
state inspired instruction was learned in an era of RF transmission
jammers located in every neighborhood so that trying to hear the VOA
or the BBC made things sound like you were listening through the
breakers of the surf. Hence the "experience" of the water model was
very pervasive and arguing its falsity comes up against the resistance
of the old guard.

It is the photons that move at the speed of light.


Photons are the math joke.
Electric waves in a medium made of electrons move at the speed of light.

Always are the two descriptions. Physical (dynamic) and geometric (kinetic).

"Geometric algebra in the sense used in this article was not developed,
however, until 1844, when it was used in a systematic way to describe the
geometrical properties and transformations of a space
"Nevertheless, another revolutionary development of the 19th-century would
completely overshadow the geometric algebras: that of vector analysis,
developed independently by Josiah Willard Gibbs and Oliver Heaviside. Vector
analysis was motivated by James Clerk Maxwell's studies of electromagnetism,
" From: http://en.wikipedia.org/wiki/Geometric_algebra


Tesla's longitudinal radio waves are also described.

For us is enough to know that the transversal are rotational. The geometric
desription of the rotational oscillations is very impressive. It must be in
the school program.

Stokes drift is also impressive. Do you know that the ink printer use it?

Movements in 2D are described on the imaginary plane, in 3D by vector
calculus, in more D by tensors.
You need not know that to analise the radio waves.
But you should know that no pure transversal waves. Always are the two
components.
Heaviside did not know that.

The Old Guard is often found trying to commemorate the past in
relation to their old heroes:
"In Paris, on August 28, 1844, at the Café de la Régence on the Place
du Palais he met Friedrich Engels, who would become his most important
friend and life-long companion. Engels had met Marx only once before
(and briefly) at the office of the Rheinische Zeitung in 1842;[28] he
went to Paris to show Marx his recently published book, The Condition
of the Working Class in England in 1844.[29] This book convinced Marx
that the working class would be the agent and instrument of the final
revolution in history."

The faded political trash that is now used as decoupage for today's
arguments is carnival in spirit but is as nutritionally substantial as
cotton candy.

As you know I am collecting the evidences. Could you tell me something about
the cristal radio?
There is the diode. The electrons flow in the one direction. The questions
a

1. Electron must flow from the antenna to the ground,
2. In the opposite direction.
3. Radio works in the both arrangement.

arguments is carnival in spirit but is as nutritionally substantial as
cotton candy.


It would be easy to collect the information from the own laboratory. But
asking is the substantial.

Nope, RF electrons don't actually flow. They essentially vibrate in
place. "For a copper wire of radius 1 mm carrying a steady current of
10 amps, the DC drift velocity is only about 0.24 nanometer per
microsecond." At 10 MHz, the electrons would vibrate back and forth at
about 0.01 nanometer per 0.1 microsecond. Consider how large 0.01
nanometer really is so for all practical purposes, electrons don't
flow at all at HF frequencies. Electrons at HF are just a bucket
brigade for the photons that deliver the RF energy to the diode
detector. Unless a circuit is at DC steady-state, photons are
involved, i.e. RF involves photons which constitute the RF fields and
RF waves.

The same is with the all AC. If between the live line and the ground is the
diode "Electron must flow from the line to the ground".

"For a copper wire of radius 1 mm carrying a steady current of

10 amps, the DC drift velocity is only about 0.24 nanometer per

about 0.01 nanometer per 0.1 microsecond. Consider how large 0.01

No matter how big the back and forth are. If is a diode electrons must flow
in one direction.
Do not be lazy and measure it.
