THE MAN WHO KNEW INFINITY: A Life of the Genius Ramanujan

In 1913, a twenty-five-year-old Indian clerk with no formal education wrote a letter to G.H. Hardy, then widely acknowledged as the premier English mathematician of his time. Srinivasa Ramanujan begged Hardy's opinion regarding several ideas he had about numbers. Hardy realized that the letter was a work of genius.

Thus began one of the most productive and unusual scientific collaborations in history, that of an English don and an impoverished Hindu genius whose like has never been seen again. Hardy arranged for Ramanujan to sail for England, leaving behind his wife and mother in Madras. Ramanujan's isolation from his family and the intensity of his work eventually took their toll, and within seven years of leaving India he was dead. For Hardy the collaboration with Ramanujan was "the one truly romantic incident of my life."

Robert Kanigel's achievement is not simply to make Ramanujan's science accessible, but to show the pleasure, the excitement, and the love of numbers that inspired it. Here is a life and a life's work that resound a century later, a testimonia to the truth that genius can flower in the most unlikely places, and a biography with all the drama, the richness, and the cultural sweep of a fine historical novel.
