I followed the link provided by BurnItUp , "When Obsessions Collide: Golf and Physics", to a lecture given by Dr. Robert Grober, prof. of physics, Yale University, and given at the Aspen Center For Physics. I liked the presentation both for its contents and the way it was given. We have...

Bronco Billy tries constantly in various ways to attract attention - his last post being particularly noteworthy for being stark naked way out in left field. :D Trying to educate Bronco Billy is like trying to lift oneself against gravity pulling on one's socks. :rolleyes: However his post made...

The Web server I used for quite some time to upload images seems to be lost in cyber space hence they are not shown any more in my posts. For now I will use another server just in case it comes back into service. But if not I will try to gradually correct the situation in past posts.

On a TGM forum there is presently a thread on ’heavy hit’. With Christmas on its way it sort of naturally led me leaning a bit towards religion viewing this thread. The Bible first was taken as is, then various interpretations/schisms, and subsequently science came along and clearly said no. As...

Everyone is so busy with serious golf business that it is time to lighten up the atmosphere a bit with a magician's trick which really is no trick but a mismatch between science and intuition. It concerns centrifugal force, this inertial force seemingly not existing for some but really joyfully...

Noticing the pleasure shown by tongzilla looking at one of my diagrams, making him even feel smarter, ;) I decided to make a few more, just for him, as I realize that most aren't really interested. I am surprised by the number of people mentioning snapping their kinetic chain as if it was...

Recently Brian has started to refer to the D-plane and many probably have been wondering what this D-plane is all about. For those interested in geometry related to golf ball trajectory just past impact have a look here.

A golfer striving to swing like a machine has to learn to control each and every element of his swing. This can easily lead to over-control and requiring continuous tuning of his complex “machinery”. :( However simply giving up all control and swinging the club almost only with the little...

Brian, Our civilization is primarily based on name giving, cataloguing and sorting things. Since that very nice notion of ‘matrix’ seemingly is not something you can use, you better come up with something to replace it. I know it is very silly but things having no name don’t really exist. ;)

The sun is slowly but steadily rising less high every day announcing nearby off-season and with Brian’s new signature - putting the emphasis on snapping the kinetic chain - it would be appropriate and interesting to start delving a bit more into this matter from a scientific point of view...

With Brian seemingly getting inspired by the concepts of biomechanic’s expert Dr. Gideon Ariel, I like to point out a serious basic error made in video segment ‘The Basics IV’ being part of ‘The Biomechanics of Power Golf’. A car traveling at high speed and suddenly braking, or perhaps even...

Brian, It appears that you have discovered Ariel Gideon and have his ideas inspire your teaching approach. ;) I do remember discussions of his ideas quite some years ago on another golf forum. Hitting against a solid left side permeates traditional golf instruction but usually without an...

golfspike, When using the expression ‘kinetic chain’ one is referring to the transfer of kinetic energy between linked moving objects. Change in kinetic energy is equal to work done. Work done is due to the presence of both internal and external forces/torques. External torques due to...

Truth seekers, please step inside.

Golfers, teachers and scientists alike have been commonly viewing centrifugal force, acting through the clubhead, as being the cause for release, i.e., the rapid take over of the club re. to the arms. We have seen previously that this explanation of the release action, as it is commonly given...

Release - 1 Release means to let go of some form of restraint - “To set free from confinement, restraint, or bondage”. There are various ways people refer to release but let’s just take above as a general definition. It might be taken as the containment of the golf club close to the body...

It is interesting to observe and speculate on Brian’s progression along the path of better understanding of all matters concerning golf. If we compare with another TGM forum where there is no progression, simply turning around in tight circles, since there is claimed to be no other knowledge...

Some musings on flexible shafts A torsionally very stiff but otherwise very flexible shaft could be a possible answer for those who can’t muscle the ball 300 yards. ;)

There are various ways to go about dosing one’s efforts in a down swing. Sharp and impulsive, slowly building to a climax or perhaps, somewhat in between, just a smooth steady action. Three such cases have been analyzed and the results show here. Note that there is always a slowing down of the...

Ringer’s apparent trouble with the subject matter of acceleration in a golf swing inspired me to put some information together hoping that it will help people easier grasp this rather difficult subject of acceleration in curvilinear motion.
