I think that all here has heard of that Gary Wiren, as the Director of Education, Learning and Research for PGA in the past, sent the book to MIT and to the University of Nebraska for a test.
The feedback was that the science was basically sound.
The interesting thing is that one of the scientists that examined the book was..........
Theodore Jorgensen
who btw was involved in the manhattan project in his early days.
