Watterson fans will recognize the rules for propagating power waves as
closely resembling those of Calvinball.

Hopefully some of those here will get that. I would be surprised if
it's more than one in four.

The rules for propagating waves of EM energy have been
nailed down for generations. Optical physicists don't
have the luxury of measuring voltage and current. They
must necessarily measure average power density. They
are quite good at it and their average power density
equations are quite accurate and mature. They obviously
know a lot more about EM waves than most of the posters
here.
