The story of Ramanujan, a young Indian mathematician, and his Cambridge University teacher, G.H. Hardy, in the years prior to World War I. The reader is taken on a tour of number theory through their eyes. Ramanujan would frequently condense 12 steps of reasoning into two; this is said to have the effect of placing Dr. Watson in the middle of a Sherlock Holmes argument. For the general reader, the language of symbols and the infinitely large (and small) areas of mathematics should be rendered clearly.
