Elliptical Pool Table - Numberphile
A game to play on the elliptical table: http://youtu.be/3WHBlPvK3Ek More links & stuff in full description below ↓↓↓ And more extra footage: http://youtu.be/pulp55gTKGE Alex Bellos'...

Ever since pool or billiards has existed, mathematicians and physicists have had these thought experiments about mathematical pool and mathematical billiards.Because it's great for working out how a particle, or in this case, a pool ball, will rebound against the sides, and where it will go.So I thought "enough of these thought experiments, lets build one!"The shape is an ellipse, and ellipses are an interesting type of shape, because they can come in a infinite number of varieties.The geometrical property of ellipses, which is why I made this table, is the fact that if you place a ball on a focus point......where ever you hit it, in which ever direction I hit it, over there, over there, over there, over there, over here, it will always rebound ...
