Do you agree with Heaviside and Poynting. Father of the famous vector
wrote
in 1884 (before the Hertz experiment):

""Energy is transferred through empty space outside the wires".
"The whole of the energy then enters in through the external surface of
the
wire, and by the general theorem the amount entering in must just account
for the heat developed owing to the resistance,"

Nope; proved incorrect or incomplete, depending on how you want to look
at it.

As you should see the energy from the transmitter enters in through the
external surface of the
wire (antenna) and next is radiated as the heat.

Nope, not a chance.

It amuses me. And what about you?

Your babbling?

Yes, it is amusing how you are always wrong.

Do you know that antennas radiate very,very lower frequences than heat?

If by "heat" you mean infrared, then yes, standard radio frequencies are
much lower than the frequency of infrared light, but you only got that
correct by accident.

"'How does energy really flow in electric circuits?'. The answer is
fairly
standard university-level physics but is rarely mentioned in secondary
school text books".

Of course not; lots of detail in every field is ommited at the secondary
school level.

In the secondary school level are electrons.
In university level are the all theories including "proved incorrect or
incomplete".
Students should know all of them.

Babbling gibberish.

A secondary school education provides an overview of a subject.

A university education provides the fine details of a subject.

What textbooks you have?

Lots; all university level and all read.

So try to pick up the theorirs which are "proved incorrect or incomplete".

The first should be Heaviside's and Poynting's.
S*

More babbling gibberish.

A textbook will rarely mention obsoleted theories.
