NOW A MAJOR MOTION PICTURE STARRING JEREMY IRONS AND DEV PATEL!

In 1913, a young unschooled Indian clerk wrote a letter to G H Hardy, begging the preeminent English mathematician's opinion on several ideas he had about numbers. Realizing the letter was the work of a genius, Hardy arranged for Srinivasa Ramanujan to come to England. Thus began one of the most improbable and productive collaborations ever chronicled. With a passion for rich and evocative detail, Robert Kanigel takes us from the temples and slums of Madras to the courts and chapels of Cambridge University, where the devout Hindu Ramanujan, 'the Prince of Intuition,' tested his brilliant theories alongside the sophisticated and eccentric Hardy, 'the Apostle of Proof.' In time, Ramanujan's creative intensity took its toll: he died at the age of thirty-two and left behind a magical and inspired legacy that is still being plumbed for its secrets today.

Editorial Reviews

From Publishers Weekly

This moving and astonishing biography tells the improbable story of India-born Srinavasa Ramanujan Iyengar, self-taught mathematical prodigy. In 1913 Ramanujan, a 25-year-old clerk who had flunked out of two colleges, wrote a letter filled with startlingly original theorems to eminent English mathematician G. H. Hardy. Struck by the Indian's genius, Hardy, member of the Cambridge Apostles and an obsessive cricket aficionado, brought Ramanujan to England. Over the next five years, the vegetarian Brahmin who claimed his discoveries were revealed to him by a Hindu goddess turned out influential mathematical propositions. Cut off from his young Indian wife left at home and emotionally neglected by fatherly yet aloof Hardy, Ramanujan returned to India in 1919, depressed, sullen and quarrelsome; he died one year later of tuberculosis. Kanigel ( Apprentice to Genius ) gives nontechnical readers the flavor of how Ramanujan arrived at his mathematical ideas, which are used today in cosmology and computer science.

From Library Journal

This biography traces the life of one of the greatest geniuses of the 20th century, Ramanujan. This incredibly brilliant Indian mathematician, working alone in relative obscurity and lacking the usual academic credentials, could easily have passed unnoticed. However, with the help of a handful of friends and the ultimate support of renowned English mathematician G.H. Hardy, his work was brought to the attention of the world. When he died in 1920 at 32 he had become a folk-hero in his own country. He left a rich lode of original mathematics, which is still being mined today. This extremely well-researched and well-written biography is a "must" addition to any library collection.

A book I didn't expect to love

ByWanda A. Adamson September 13, 2016

Format: PaperbackVerified Purchase

This is one of those books that you'd think I'd be the last person in the world to read. I once had a teacher who really liked me write me an award certificate for having achieved a C- in Algebra (I was an A student in all other subjects except, of course, PE). However, this is an example of non-fiction so well-written that the subject takes a back seat to the pleasure of reading, exploring a different world and seeing into a unique mind. Highly recommended. I've yet to see the film but Patel's one of my faves so I'm looking forward to it.

Great supliment to the movie

BySMB.on October 22, 2016

Format: Kindle EditionVerified Purchase

Well documented. An eye opener into the culture of South India. Full of real detail and input from other mathematicians with regard to Ramanushan's contributions. Read it after seeing the film. Filled in many details which could not ever be included in a 2 hour film.

Good story and very interesting subject

ByRobert B.on June 23, 2016

Format: Kindle EditionVerified Purchase

Good story and very interesting subject. Even after being prepared by the preface about how he will go into the history and upbringing of Ramanujans life etc, the writing was ..so so. It read more like a history book than an actual biography. I had no problems with the math portions in the body. I actually enjoyed them.

Not to Be Missed

Bysusan613on October 18, 2016

Format: Perfect PaperbackVerified Purchase

A superb, detailed and insightful treatment of the personalities of three great mathematicians, and of the interesting times
in which they lived. The mathematical information can easily be skipped if the reader is not keen on that sort of thing.
Also, it points out the many falsehoods contained in the visually beautiful film of the same name.

I have been fully attracted and fallen deeply into this book

ByAmazon Customeron April 28, 2017

Format: Kindle EditionVerified Purchase

The life in India and the research in British are two things that I am interested in. This book provides both. I have the chance to know the two great mathematicians and how they created the legend in the Mathematics history.
I am gripped by the author's style of writing and spent around one year to finish the reading in my spare time. I marked the beautiful and the just perfect words and phrases as I am learning the language.
If the reader wants to explore the secret of the life in India and to understand the progress track of the Western research, I recommend this book, especially to those who are not familiar with India and British.

A must read, especially after the movie .

ByAviva Ronon July 2, 2016

Format: Kindle EditionVerified Purchase

An incredible book, with the historical background of Hardy and Ramanujan that makes it all the more interesting, and gives the societal background of Britain and India. Almost made me want to study mathematics again.

Stunning Portrayal of Genius

BySpiritShouton October 2, 2016

Format: PaperbackVerified Purchase

Stunning Portrayal of the Genius Ramanujan. Would Cambridge Mathematics professors be Jealous of a man who could finish up a new mathematical idea they were working on for months, in a matter of minutes ? They certainly would ! and they were jealous of Ramanujan, denying him as a fellow in their august society, until it was so obvious that he was another Euler or Newton, that they had no choice but to accept him. The Mathematician, G.H. Hardy, played brilliantly by Jeremy Irons, was made greater by his assistance of this God touched Math Wizard. Mathematics is very deep thought on the simplest ideas in the world, and it is this depth, this sense of Numerical Order and Lawfulness, that made Ramanujan pour out beautiful equations until almost his last breath. Many of these Equations will not find an application for hundreds of years. Of course in Mathematics, you can't just produce an equation or a nice series without Proving that it is in fact a truth statement. It was learning to do the rigor of proofs that slowed Ramanujan down in his zeal to give Hardy his heady jewels of symmetrical numerical wonder. But in the end, Ramanujan did learn the art of the Proof and was a published contributor to the deepest and most vast field of all...the Queen of the Sciences...Mathematics. I know, that if you have even a smidgen of respect for the Gifted among us, you will love this Film.

ByAmazon Customeron February 2, 2017

Format: Perfect PaperbackVerified Purchase

Arrived as portrayed, well packed. Wonderful background establishing a gradual relationship between the reader and the main characters involved. It is like one would actually want to have a conversation with the characters as the author makes known their genius, temperament and struggles during the particular years they live in.
