	We have all had teachers like that.  Mine found out
	the hard way that some of us knew more about van de
	Graaf generators than he did.

	And many of the best and the brightest SINCE THEN,
	or, rather, the best and the brightest who have chosen to
	practice electrical and electronic engineering, have
	repeated the experiments.  Over and over.  And gotten better
	and better understanding.  Entire books are filled with
	the results of these tests.  The 'uniformed opinions'
	are those of a century of people, who brought us television,
	radio, pictures from Mars, Jupiter, etc.
