To play billiards well (the sign of a mis-spent youth ?) requires a sharp eye and steady hand, but also a profound physical intuition.
The game is not unlike elementary—particle physics played at giant accelerators, where tiny particles are made to collide, but with two big differences : Billiard balls are bigger than atoms so quantum mechanical uncertainty is irrelevant---we may imagine shots to be set up with arbitrary precision. Billiard balls travel much less swiftly than light so relativistic effects are irrelevant as well---we need not fear a collision of two billiard balls to produce a third. Newton’s laws in action---Can there be a more pleasurable introduction to physics ?
