HOT: A Disappearing Number, Barbican

A really imaginative production of a play about mathematics and its impact on two intertwining relationships - the Cambridge mathematician GH Hardy and Indian prodigy Srinivasa Ramanujan, and on the other hand Ruth, a mathematician obsessed with Ramanujan's work and her husband. There was great use of Nitin Sawhney's music, videos and images, moving screens and dance. I really like the Barbican too, with its fountained courtyard and sixties concrete exterior.
