Oscillating (vibrating) molecules is a measure of heat energy.

It apply to the air molecules.

With
that explanation, it would be necessary for antennas to be hot in
order to radiate. Try again please.



But no smaller species than the electrons.

Other than positive electrons, there is only one type of electron.

Tunnig fork transfer its energy to air molecules, air molecules to
electrons
and no next step.

As I previously mention, pneumatic analogies do not work well for
describing RF radiation.

The same is with the electron waves speed and the electron beam (drift)
speed.

Same as what? There is no such thing as an electron wave.

There no such thing as the EM waves.

Nice dodge. Answer my question... same as what? What is the same as
your electron wave?

There are
electron beams, and radio waves, with very little overlap.

Like wind and sound.

Which is like an electron beam? Wind or sound?


Which is like a radio wave? Wind or sound?
How are they like each other?


The wind of course.
Sound is like the electron waves.

If think that electrons fly off the ends of an antenna, there should
be a way to directly detect those electrons. For example, a CRT has a
phosphor screen that lights up when hit by electrons from the electron
gun. If your mythical electrons are really there, you should also be
able to place a phosphor screen near a transmitting antenna, and have
it light up.

Cathode rays were idenified in 1895.

My antennas do not emit cathode rays. If they did, my neighborhood
would be bombarded with electrons, potentially destroying everything
it its path.

The cathode rays travel to the anode.

Please produce a reproducible test, that will demonstrate that charged
electrons are being emitted by an antenna. Your Nobel prize awaits
you.

It was done before the first Nobel prize.

Also, if your electrons are leaving the antenna, and flying off into
the ether, there should be a rather large positive charge left on the
antenna.

You call it "static".

Static electricity? The word "static" means not moving. With static
electricity, surplus electrons (or lack of electrons) are accumulated
on an object, giving it a negative (or positive) charge. The point is
that they are not moving, just sitting there.

They travel into the earth.

Ever try to stop an RF
signal? You can't. You can slow it down through various materials,
but you can't stop it. RF and static are not the same. Try again.

If you then claim that the transmitter is replacing the
electrons as fast as they are radiated, then the positive charge
should reside in the transmitter. If you then claim that the local
electric utility is supplying electrons to the transmitter, then the
utility generating station must have a huge positive charge.

For this reason the all electronic equipment have the
earth/chassis/counterpoise as e remedy.

In case you haven't noticed, power lines are a balance pair. For 3
phase, they are also balanced at 120 degrees apart. The ground
connection is strictly for safety and is not required for proper
operation.

Totally wrong. The power lines and receiver antennas must have ground
connection.
"The wire antennas used with crystal receivers are monopole antennas which
develop their output voltage with respect to ground. They require a return
circuit connected to ground (earth) so that the current from the antenna,
after passing through the receiver, can flow into the ground. The ground
wire is attached to a radiator, a water pipe, or a metal stake driven into
the ground.[4"

It's there for safety, in the event you decide to prove
your theory by discharging the mythical positive accumulated charge to
ground through your body.

It could not be wrong because such Giants as Ampere, Faraday, Stokes,
Lorenz, Tesla and Dirac were "using real world examples and numerical
calculations."

Pick one sample calculation that demonstrates that electrons are being
emitted by transmitting antennas. There are plenty of tests that will
detect electrons. Pick one.

Ampere, Faraday, Stokes, Lorenz, Tesla and Dirac analyzed and explained
everythig.

True, but you haven't explained anything.

Thank you for the history refresher. Unfortunately, I didn't see
anyone claiming that antennas emit electrons. Could you be a little
more specific.

"a small segment of current" = electron.

Segment? So, if I take a conductor, and cut out a segment, I can walk
away with several amps of current contained in that segment? Amazing.

"the Biot-Savart law" = hydraulic analogy.

http://en.wikipedia.org/wiki/Biot-Savart law
I fail to see any mention of hydraulics in the above article. Also,
your analogy was pneumatic, not hydraulic.

"The electronic-hydraulic analogy (derisively referred to as the drain-pipe
theory by Oliver Heaviside) is the most widely used analogy for "electron
fluid" in a metal conductor".

In EM is "electron fluid". In science "electron gas".

Teaching and science are the two different things. In teaching is the
hydraulic analogy in science are electrons.

I'm sure the teachers in this group will be thrilled to know that what
they're teaching is not science.

Jimp is a teacher.

"It is unfortunate that electrodynamics and relativity decide in favor of
Biot and Savart rather than for the much more sophisticated Ampere".

If there's a conflict, simple explanations tend to prevail.

Sophistication is for science fiction.

Here no conflict. The hydraulic analogy is enough for kids.
