Everything you need to understand or teach The Man Who Knew Infinity by Robert Kanigel.
The Man Who Knew Infinity is a book about two important mathematicians, their relationship, and how it shaped their lived and the world around them. One of these men, Ramanujan was a genius of unusual strength who would go on to develop some of the most interesting mathematical conjectures and theorems of the century, if not of all time. Yet he had only the most bare education in backwaters of South India. The other man, G. H. Hardy, was the most respected English mathematician of his day and the product of the best schools in England. Ramanujan was a genius, but it took Hardy to recognize and bring the young man to England. For several years, their collaborations at Cambridge produced mathematical research that is still be mined today for interesting results.
The book begins in South India where Ramanujan was born and lived most of his life...
