Please realize that it's not the definitions of fundamental
principles that are different. It is the definitions of the
random grouping of letters called words that are different.
The same word represents different valid fundamental principles
in different disciplines. "A rose by any other name ..."

Physics simply does NOT have a monopoly on the word "power".
There are 32+ definitions of power in my dictionary.

P-O-W-E-R has a different definition in RF engineering than
it does in physics. It doesn't mean that there's anything
wrong with anyone's fundamental principles. After all, the
Russians and Japanese don't even use the word "power" for
any of their fundamental principles which are just as valid
as yours.
