A Disappearing Number

A Disappearing Number weaves together the story of two love affairs, separated by a century and a continent. The first happens now. The second is set in 1914. It tells of the heartbreaking collaboration between the greatest natural mathematician of the 20th century, Srinivasa Ramanujan, a penniless Brahmin from Madras in South India, and his British counterpart, the brilliant Cambridge don GH Hardy.
