A mathematician named Alex Bellos demonstrates his custom-built elliptical pool table in which everyone wins. The explanation of this is that it can be used to demonstrate elliptical focus points. When the ball is shot from the complementary focus point from the hole it should always go in, regardless of the direction of the shot.
Because a traditional game of pool would be impossible to play on the table, Bellos also invented a game called “loop” which uses the table and four balls to make the most out of the table’s unique properties. Numberphile videos presents the full demonstration by this creative matematician you can see it below.
