For practical engineers the math theory is useless.
But for real engineers math is everything. If you can't back it up with
figures, you're only guessing.
The figures are also in empiric equations. Engineers use only such.

you have obviously never been an engineer... except maybe the type that
drives a train.
In this book:

no equations, no terms like transversal and so on. Sometimes the Authors
include a math theory. Each math theory has some simplifications. In nature
not separate transverse and longitudinal waves. The math is separate.
Maxwell was the genius. He made the ether model as a solid body. For Him it
was very easy. He also wrote 60 pages of equations for the Saturn rings. He
was also able to write a math for liquid or gas ether. But he lived too
short.
I wanted to know if radio people observe the frequency doubling when
receiving signals from a dipole. It should be easy to check it.
For me is enough to know (from this Group) that such was observed and is
known as the Luxembourg effect.
