Considering the overall volume of postings here and the fraction of
world population that the Poles are, I don't think it is statistically
surprising that you see only a single Pole here.


Makes me think back to an old joke from EE at college involving Poles,
zeros and the right half of the (air)plane.

And I am Polish so I can make fun of my heritage. Our last name was
quite different when my grandfather moved to the US.

Hello Szczepan.

Actually, yes, you are the poster. You copy and paste and post. The
problem
is that you often don't understand the meaning / import of the text which
you are copying and pasting and posting nor do you learn from the postings
made in reply to you.


So we have the three teams of posters:
1. Faraday, Stokes, Lorenz, Marconi, Tesla and Dirac,
2. Heaviside and Poynting,
3. You, Tom, Rob and Jimp.

From whom should I learn?

Do you know:
""Poynting and the Nobel prizewinner J. J. Thomson co-authored a
multi-volume
undergraduate physics textbook, which was in print for about 50 years and
was in widespread use during the first third of the 20th century.[5]
Poynting wrote most of it.[6""

For example in the textbooks the water waves are "transversal" and the space
is empty.
In the above link you can see that the water waves are longitudinal.
Have the stars the atmosphere?

Hello Szczepan. Teams 1 and 2 do not exist, do they? Faraday and the others
aren't sitting at computers and making posts, are they?
You're making posts with text that you seem not to understand. This confuses
you even more and amuses us.

From modern sources that have corrected the errors in the theories of over
a hundred years ago.

Do you know:

multi-volume

Yeah, so what?

is empty.


Gibberish.

So what?

This is an antenna group not a boating group.

Unfortunately one is in the left half of the plane and the other in the right
half of the plane so we are a bit lacking in stability.

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,"

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.

It amuses me. And what about you?
Do you know that antennas radiate very,very lower frequences than heat?


"'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".

What textbooks you have?

The coherent RF energy flows near the surface of the conductor at the speed of light in clouds of photons. Given the magnitude of the Poynting vector, we can calculate the number of photons passing through that area in unit time. Those coherent photons that extend into the inner surface effect area have the highest probability of their energy being converted into infrared higher energy photons, i.e. heat radiation. After all, RF photons cannot exist for long deep inside a real-world conductor and they cannot exist at all inside a zero resistance conductor. Here's a question for you: How many 10 MHz photons does it take to generate one infrared photon?

Only steady-state DC doesn't involve photons. All AC, RF, and transient DC functions involve photons and that has been accepted as scientific fact for about a century. Unfortunately, the physicists being quoted by you were completely ignorant of the existence of photons.

Hello Szczepan.
I am a licensed radio amateur and I am concerned with matching my aerial to
my transceiver. I'm personally not at all concerned about any heating
effect, theoretical or actual. Sounds like a topic for one of the physics
newsgroups.
As for textbooks, I have a shelf of them. You'll remember the
recommendations I made in other posts.
Regards, Ian.

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

Nope, not a chance.

Yes, it is amusing how you are always wrong.

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.

So what.

What textbooks you have?


Lots; all university level and all read.
