Following 2013’s amazing bounded gaps between primes result, mathematician Yitang Zhang has gone from an unknown maths lecturer to a mathematical celebrity. The Mathematical Research Sciences Institute at Berkeley has put together a film telling the story of Zhang’s proof, and his life before and after the announcement.

The film, which was funded by the Simons Foundation, has contributions from a large number of mathematicians, including Daniel Goldston, Kannan Soundararajan, Andrew Granville, Peter Sarnak, Enrico Bombieri, James Maynard (based at Oxford, who did further work to reduce the prime gap following on from Zhang’s), Nicholas Katz, David Eisenbud, Ken Ribet, and Aperiodihero Terry Tao, as well as Zhang himself.
