Introduced by Ron Graham

Ron Graham holds the world record for the highest number ever used in a mathematical proof, known as Graham's number. A former president of the American Mathematical Society, he is currently Chief Scientist at UC San Diego's California Institute for Telecommunication and Information Technology. Graham was a close friend and collaborator of Paul Erdös; his introduction will touch on Erdös's career and the making of N Is a Number.

A man with no home and no job, Paul Erdös was the most prolific mathematician who ever lived. A wandering genius, Erdös, who died in 1996 at the age of eighty–three, spent his life engaged in a cosmic struggle to uncover truths hidden by a stubborn adversary-God. In N Is a Number he describes this metaphysical duel with the same wry humor he applied to politics, relationships, and death. Following Erdös through four countries to discover what makes mathematicians tick, the documentary presents his mathematical quest, its personal and philosophical dimensions, and the tragic historical events that molded his life. Animated sequences help enliven the kind of mathematical problems Erdös pursued, offering further insight into a man once described as "the prince of problem solvers, and the absolute monarch of problem posers."
