mandrin, your's is an exercise in futility. Attempting a peer review of TGM when the author is deceased is about as useful as passing gas in the breeze, you just stink things all up.
Homer was not an engineer nor a scientist, only an aircraft technician who equated the golfswing in hydraulic terms, eg accumulator. He proclaimed his Science by only quoting Newton's Laws of Motion and then used poetic licence to invent convenient terminology to get his idea's across while contradicting Newtonian Physics.
Please understand that in the 1960's when Homer came out with TGM, there was absolutely no scientific analysis of the golfswing that linked the science to the golfswing. SPS was just a compendium of interesting informational facts, but did not provide any linkage to executing a golfswing, as Homer bravely attempted. The most scientific treatise at the time was Hogan's 5 Lessons and the concept of the illusory "swing plane". Even Hogan got confused between "feel" and "real", but that was irrelevant because he won tournaments and that's what counts.
There were, and are, no great minds in golf; only great golfswing teachers, some of whom have gleaned the essence of TGM and incorporated it into their fine teaching methods. Even they cannot fully understand TGM because it is so poorly written and badly organized. If TGM was an aircraft instructional manual, the plane would crash before it took off. Nevertheless, Homer did make some interesting contributions to the art of golf with his "pressure points" definitions. However his badly done hand sketches seemingly contradict his explanations to further deepen the mystery surrounding the masochistic aura of his writings.
Truthfully, if Homer were an engineer he would have been declared incompetent because TGM is replete with outright error, eg page 80 where he proclaims:
6-C-2-B ANGULAR ACCELERATION The Clubhead "overtaking" speed is governed by the Law of Conservation of Angular Momentum whereby the increasing Mass resulting from any extension of the Swing Radius decelerates the Hands ....
Perhaps Homer misspoke himself when he refers to "increasing Mass" because the Mass is constant whereas the Moment of Inertia increases when the Swing Radius increases. Homer should have caught this error unless he was oblivious to the Newtonian science he depended on. If a graduate engineer had published such an explanation under his name, his book would have quickly been relegated to the fireplace!
Another gaff occurs at page 15, where Homer gets twisted up explaining force vectors at:
2-C-O LINEAR FORCE The ball will respond to non-linear (angular) force exactly the same as to linear forces ......
All forces are linear, but it appears that Homer perceives torque as a "non-linear" force. How unfortunate and how revealing of Homers abject ignorance of the Newtonian science he proclaims that validates his golfswing theory. Homer ain't no engineer nohow.
What is even more disconcerting than the potpourri merry-go-round of references in TGM, is the total lack of calculated proofs behind Homer's science. He uses scientific words such as momentum, force, mass, inertia, energy, power, velocity, acceleration, etc. but does not provide any numerically calculated proof behind his assertions and proclamations - not one. Doesn't that raise any suspicions amongst his advocates? Probably not because the only number that counts is how far can you hit the ball apparently using TGM.
Other engineering blunders such as the Endless Belt Effect and Line of Compression are too devastating to present to the faithful here. It is interesting to note that nobody scientific refers to TGM as an authoritative work. Wonder why?
Nevertheless, Homer's monumental effort to define the golfswing is like a wake up call for the scientific world to rescue golf from the brave efforts of laymen such as Homer. We now have interesting books such as by Jorgensen and others, and the presentation of scientific papers on golf at the World Scientific Congress of Golf held every 4 years at St. Andrews University preceding The Open. But still we do not have one Grand Unifying Theory to connect the sciences to the golfswing of the struggling golfer.
Keep up the good work Big Chief Brian M to help all the Indians with their Arrows .... while doing the TGM swing dance !
Perhaps it was best put by H. Penick when he observed in his Little Red Book - "The golfing area of the brain is a fragile thing that is terribly susceptible to suggestion. Golfers are gullible." Yes ignorance is bliss when accompanied by a 280 yard drive straight down the pipe.
