Complicite's A Disappearing Number is about the unbearable brightness of romancing the infinite and how it burns everything else in one's life to a crisp. It is also about the unrealish encounter between two great mathematicians of the twentieth century, Srinivasa Ramanujan, a poor Brahmin from South India, and Cambridge University don G.H. Hardy. Most of all, it is about Mathematics as a muse – dark and alluring to a few and a total turn-off for most. Until they have been to the play, that is.
