how can you say i dont need to know this to play great?Fundamentals have to do with the grip on the cue, stance, head/eyes/body alignment, AIMING and coordination to perform it. Blind people can't play pool because they can't SEE to AIM. It's physical just like all sports.
When pool was first invented and all throughout the depression, men flocked to pool rooms because there was nothing else to do. They knew absolutely zippity do da about physics and never did even though it was present. Knowledge of physics and geometry as taught in books and classrooms had nothing, absolutely nothing to do with the success and caliber of a player all
throughout history from then to now. Some of the best players in the history of pool weren't very bright intellectually to begin with. Actually, quite dense and even drunkards.
Did physics take place? Yes. But totally unnecessary to learn and know from studying science in books and classrooms and then preaching it as you do. You do it to put yourself on a higher pedestal due to your inadequacies in the actual physical performance of it. It's all you have going for you along with a few nut huggers all throughout the last 25 years that echo your babble.
