The story of the Indian mathematician Srinivasa Ramanujan (1887–1920) is improbable. Self-taught, he made many seminal discoveries in number theory and power series — most famously concerning the partition of numbers into a sum of smaller integers — that continue to fascinate mathematicians and intrigue physicists studying black holes and quantum gravity. In The Man Who Knew Infinity, director Matthew Brown dramatizes the purest of mathematics for a general audience, and explores the strange personal life of Ramanujan, who died at 32, at the height of his powers, probably from tuberculosis. Based on the compelling biography of the same name by Robert Kanigel (Scribner, 1991), the film took more than ten years to create. It is worth the wait.
