NOW A MAJOR MOTION PICTURE STARRING JEREMY IRONS AND DEV PATEL

A moving and enlightening look at the unbelievable true story of how gifted prodigy Ramanujan stunned the scholars of Cambridge University and revolutionized mathematics.

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...

An Extraordinary Biography

This is a captivating, illuminating, and deeply moving biography of the Indian mathematical genius S. Ramanujan. Genius is always enigmatic, and mathematical genius doubly so to the general reader for whom math will always be a closed book. One of the extraordinary things about this biography is Kanigel's gift for mathematical exposition at the layman level. As a mathematician myself, I can only say I've never seen its equal. Although to some extent he is helped by the "elementary" nature of much of R.'s work -- its gist can be grasped with only a basic understanding of calculus -- the task is still daunting. Yet everything is clearly and correctly explained, freshly, succinctly, memorably. Kanigel's book is equally rich in human terms, too. His portrait of R. shows not only a genius but also a simple, spontaneous, likeable man. R. must have been the world's worst math tutor -- one shudders at the thought -- yet people liked him. This was a crucial factor in R.'s getting the opportunity to bring his gifts to full flower, for heaven and earth had to be moved. It's sad to think of the other Ramanujans in India and elsewhere who, crushed by life's hardships, were never able to develop or perhaps even recognize their gifts. I take issue with the previous reviewer concerning Kanigel's treatment of Hardy. Hardy is a complex and fascinating figure in his own right and his personality needs to be explored in the context of his relationship with R. His homosexuality was a part of the constellation and a factor in his championing of the underdog (including women in mathematics), his openness to the unorthodox, and his willingness to take risks. Although bound by their common love for mathematics, the two men were otherwise poles apart both temperamentally and culturally. This contrast adds further interest and poignancy to the already romantic, Cinderella-like story of R.'s brief life in this world, and Mr. Kanigel makes the most of it. Urgently recommended!

Inspirational account of the life of a Mathematical genius

An Inspirational account of the life of a Mathematical geniusSrinivasa Ramanujan is rightly a member of the Mathematicians' Hall of Fame. From humble beginnings in the small town of Kumbhakaon in Tamil Nadu to the hallowed cloisters of Trinity College, Cambridge, this magnificent book narrates the story of Ramanujan's trails, tribulations and triumphs.Central to the story are the powerful influences of Ramanujan's mother and the great English Mathematician, Godfrey Harold Hardy. If his mother, Komala shaped the first part of Ramanujan's life, then surely Hardy must take full credit for bringing Ramanujan's prodigious talents to the attention of the world Mathematical community. Other prominent characters also figure in the story - notably Ramanujan's many friends, Narayana Aiyer, Gopalachari, leading lights in the Indian Mathematical establishment, members of the ruling British classes, Sir Francis Spring, the Governor of Madras Presidency, and Cambridge Mathematicians, Neville and Littlewood.The book presents a touching portrait of Ramanujan the man: an orthodox Vaishav Bhraman, steeped in Hindu culture with all the attendant characteristics of a deeply spiritual outlook, a calm self-assurance about his abilities, and most of all, an obsession with Mathematics. Hardy, his mentor, is also biographed as the passionately atheist, Winchester educated son of a middle class schoolmaster who went up to Cambridge, and at the turn of the 20th century, almost single handed masterminded the rise of English Pure Mathematics.

A touching biography

Im not too fond of biographies, but I would give this book an exception.The life of Ramanujan is amazing and one is pushed to only awe the limits of mind. Being an Indian, I can see Robert Kanigel has given a comprehensive treatment to all facets of the life of Ramanujan - his boyhood days in small town of Kumbakonam, his obsession with Maths, his seperation from Mother and his wife, his relationship with Hardy and others, his stay in London, and his final days. Kanigel has really done a wonderful job in depicting the Brahmin house-hold of the early 1900s. One could really imagine Ramanujan with a tuft and a religious symbol on forehead, but his mind calculating 10,000 th decimal of pi.His purely professional relations with Hardy has also been very deftly depicted. How hard the days must have been! Being a Ramanujan's biography its hard to avoid mathematical formulas - and the author justifiably includes them when necessary. But even if you do not understand them - you can just wonder at the string of symbols joined together to purport some meaning.The narration is truly captivating. It sends an horripulating feeling to the mind, when Hardy describes the first letter of formulas as "These must be true. If they are not, nobody would have the audacity to invent it."The final days of Ramanujan are indeed sad and emotional and also beautifuly captured in the book. Typical is the life of geniuses - the world has hard time understanding them. This book is really worth in my library.

An excellent book for people who love Science and History

In each field of science there are many unsung heroes whose stories are all but forgotten. Nevertheless some of these stories are astonishing and in the hands of a good author makes fscinating reading. One such story is that of Ramanujan, who was to Math what Mozart was to music. His genius was almost mystical. This book deals with his life, how came to the attention of Hardy, went to England and became one of the well known mathematicians of his time. But this book also deals with the "mystical" aspects of his genius. Strange, almost unbelievable anecdotes of how from the esoteric shadows of the east came an almost uneducated man who, isolated from the scientific world, rediscovered many of the great mathematical theorems that had been dsicovered over centuries in Europe. The book is written in a superb style. I really enjoyed reading it, and I urge everyone to read it for its sheer entertainment value
