Why did I love this book?
I think the life and the work of Ramanujan is the most astonishing story of any mathematician. Everybody knows that 1/2 + 1/4 + 1/8 + ... adds to 1. Ramanujan wrote down infinite series like that but of amazing complexity. He was a self-taught and unknown genius in India, who found his way to England. His ideas are still being explored and developed— they go to the heart of mathematics. This book and the movie are simply inspiring.
