The Man Who Knew Infinity by Robert Kanigel

"From the remote rural district of Tamil Nadu in South India to the hallowed halls of Cambridge University, 'The Man Who Knew Infinity' charts the incredible journey of Srinivasa Ramanujan, a self-taught mathematician whose groundbreaking contributions to number theory, continued fractions, and infinite series revolutionized the field.

Author Robert Kanigel transports us back to the early 20th century to explore the life and times of the 'divine mathematician' Ramanujan and his friendship with G. H. Hardy, a professor who recognized and nurtured his genius. Defying the severe constraints of his upbringing, poverty, and deteriorating health, Ramanujan's self-belief and love for numbers remain undeterred, leading to a burst of profound mathematical insights, some of which are still being studied and expanded upon today.

In this inspirational biography, Kanigel explores the passionate intellect, indomitable spirit, and extraordinary talent of a man who dared to dream beyond his humble beginnings, transforming the field of mathematics forever. The book was the basis for the film of the same name and is an absolute must-read for those interested in the inspiring tales of scientific genius."
