## Plus Advent Calendar Door #22: Happy birthday Ramanujan!

Submitted by Marianne on December 22, 2012Today would have been the 125th birthday of the legendary Indian mathematician Srinivasa Ramanujan. This self-taught genius formed a remarkable working relationship with the mathematician G.H. Hardy which served as inspiration for the 2008 play *A disappearing number* by Complicite. Read our article on the play and some of the maths behind it, our interview with an actor/mathematician involved in the play, and an article featuring one of Ramanujan's contribution to number theory.
