I'm preparing an article for a local radio club magazine about the nature
of
radio and electromagnetic radiation in general. While this is a non
mathematical and general descriptive treatment of the subject it is a
challenge to make it clear and consistent.
I know this group has some expertise on this subject and would appreciate
any constructive comment and suggestions regarding the attached article.

Thank you for your time.

Albert Einstein is frequently quoted saying: "The wireless telegraph
is not difficult to understand. The ordinary telegraph is like a very
long cat. You pull the tail in New York, and it meows in Los Angeles.
Here is the drawing of the cat:

The wireless is the same, only without the cat."
There is a small difference. If instant of the cat (wire) is an insulator
(aether) in it flows the displacement current. The current is strong when
the capacitance and the frequency is big. It is easy to achive the huge
frequency but for this you must use the modulation.
