So I have this PhD in physics, you see, but never became a physicist. So I can't really muster either an awe or a deep collegial appreciation for the science, one of which you'd have to have to really appreciate this book fully. Instead, I just wonder why he didn't apply his torque argument to the horizontal component of the swing plane. Still, I have to appreciate a data-based approach to the swing and found some satisfaction in the author's dissatisfaction with verbal, feel-based, analogous descriptions of the golf downswing. And I took away a couple of things to try, which is always good. ( )
