your source, and yet unable or unwilling to confront this single

Apparently that would mean the waves aren't traveling at the speed of
light and it would violate his "waves cannot exist without energy" law
of physics, so therefore the book is wrong. Besides, as a reference,
Hecht is far more maleable. ;-)

Hi Jim,

It is far more reminiscent of his proof of total cancellation, if you
accept that total allows for several percent of non-totality.

Such vague indifference is like building the Golden Gate and finding a
gap of 40 or 50 feet in the middle. "Who's gonna' mind a couple of
percent? It spans the total bay, and THAT'S what counts!"
We have a bridge builder that wouldn't cross that bridge if he came to
it.
