Are you guys serious with this stuff? No disrespect intended, but this sort of thinking will ruin my game. I am gone.

murf, of course we are serious about this stuff. This board welcomes exploring just about any facet of the game, whether it be the thought of 'keeping your head down' at impact to whether or not the conservation of angular momentum exists.

Members are encouraged to make it as simple or as complex as they wish. Just try to back up your thoughts with facts and/or somewhat reasonable logic and respect each other's opinions whether or not you agree with them.

The problem I believe with popular golf instruction is that it's woefully incomplete and horribly afraid of getting into detail. Of course, the end user needs to be able to understand the topic at hand, but they always have the choice to opt out of trying to understand it. I don't think Fred Couples would know D-Plane from Dee Snyder, but I believe for the majority of golfers it would be extremely helpful to understand exactly how the golf ball flies.

The problem I have with popular instruction, particularly in golf magazines, is that they assume that everybody is Fred Couples. I'm sure most of the golfing world would love to be Fred Couples and not have to worry about it and just crush the ball every day of their life. But I believe that most people sort of need to know what they are doing so when a shot goes awry, they are now on the correct path to fix it.

So again, I greatly encourage this exploration because I believe that's how great things are discovered, by an open mindedness and daringness to explore things we never considered before.

Jeff,

Out of curiosity. Can you tell me what the e-mails to Dr. Gracovetsky were about with spine mechanics? Does he really believe in the spine engine theory in Kelvin's articles?

Dr. Gracovetsky is the originator of the "spine engine" theory. Kelvin summarised his theory on his website. I wrote to Kelvin about one month ago and he sent me a 18-page pdf file that he had written on Dr. Gracovetsky's "spine engine" theory. When I questioned certain aspects of the "spine engine" theory, Kelvin sent my "contrary opinions" to Dr. Gracovetsky, who then sent me another paper to read (via Kelvin). I never personally communicated with Dr. Gracovetsky. I only communicated with Kelvin. After reading that additional paper, I stated that I found the "spine engine" theory incompatible with my understanding of human spinal anatomy/biomechanics. Kelvin and I have not communicated about this topic since that last e-mail communication - except that Kelvin helpfully told me how he created his animated gifs (and I now also love to create animated gifs to demonstrate certain golf swing motions in slow motion).

Jeff,

I thought you said you were a retired physician and its obvious you have a great anatomical understanding, was the back your area of specialty?

Greg,

My medical speciality was Emergency Medicine. I also happen to have a BSc degree in anatomy and physiology and I spent two years dissecting cadavers.

I only studied the anatomy/pathophysiology of the spine in depth when I had surgery for a herniated disc about 13 years ago.

I did evolutionary anatomy. I could tell you about it in a gibbon, a number of other extant primates and our various hominid ancestors over the past eight million years. Not a huge amount of use for this discussion... or anything else, for that matter.

[cloran]

I studied Co-Ed anatomy in College... not much use in this discussion either
