let the author know so he can correct in the next ed.

I like this one! It reminds me of a mechanical engineering book I got from my late father in law, a book he received from someone even more senior. Under radio frequency waves it states that this is a wonderous and strange phenomenon that is yet to be explaineth. And here I am an RF guy...
