# National Mathematics Day: From Infinity to beyond, Counting 130 years of 'Ramanujanism'

These five books have been penned by reputed personalities documenting the life, work and inspiration of Srinivasa Ramanujan whose love for Maths changed the course of the subject in India

From Kumbakonam to Cambridge this Erode-born Math wizard mastered Trigonometry at an age of 12 and in another 20 years, this self-educated Mathematician's significant contribution to the subject created the history. Srinivasa Ramanujan, born in an orthodox Tamil Brahmin family, ran out of house to pursue his study in Mathematics.

**#1 The Man who knew Infinity: A life of the Genius Ramanujan**

Biography of the Indian mathematician Srinivasa Ramanujan, written in 1991 by Robert Kanigel and published by Washington Square Press. The book gives a detailed account of his upbringing in India, his mathematical achievements, and his mathematical collaboration with English mathematician G. H. Hardy

**#2 The Indian Clerk**

The novel is framed from the perspective of mentor and collaborator, through a series of lectures that Hardy gave on the subject of Ramanujan's life and mathematics at New Lecture School at Harvard in the summer of 1936 and the narrative switches between Hardy's recollections and the events of the 1910s when Ramanujan was in England.

**#3 My search for Ramanujan: How I learned to count**

Ken Ono is the Asa Griggs Candler Professor of Mathematics at Emory University and a Fellow of the American Mathematical Society. This version is one that brims with inspiration, a personal experience woven to portray and the life of a mathematician (Ono) who followed the footsteps of the Indian genius.

**#4 Ramanujan: The Man and the mathematician (Great thinkers of India)**

A collection of memories reminiscent of Ramanujan by several surviving contemporaries, this book brings to the fore the man's simplicity and "penetrating intuition". Considered a 'seer' in mathematics though agnostic in arguments, he was a believer in the immanence of God.

**#5 Ramanujan's Lost Notebook: Part I **

A posthumous discovery, a manuscript which had recorded mathematical discoveries during his last years. All but a few mathematicians knew about its existence until it was rediscovered by George Andrews in 1976. The notebook consists of 100 pages written on 138 sides in Ramanujan's trademark handwriting. The treasure? Over 600 mathematical formulas listed consecutively without proof.
