PI : Mathematics is the language of nature.
The story of the movie PI, a mathematical number involves Max Cohen, a paranoid and reclusive New York math genius, confined to his messy apartment behind a door with three locks, and who talks to his homemade supercomputer, Euclid, trying to detect a pattern in the chaos of the universe-in the digits & pi, in the rise and fall of the stock market, and in the letters of Torah. Cohen is also affected by a rare brain malaise, which causes him to have wild uncontrollable fits and hallucinations.
Well the tale is bit weired, but guess what, most of the genius behaves the odd way so did max cohen.
