Pi

David is asked by a member of the public to try and understand Pi, and what it means for its digits to continue infinitely. He starts out with a mathematician and the biggest circle he can find, and then tracks down a philosopher. But can he understand it well enough to explain it himself - to one particularly demanding member of the public?Producer: Giles Edwards.
