Srinivas Ramanujan: The Man Who Knew Infinity and Beyond

We have all had our share of Mathematics’ stories growing up. For 90% population out there in schools and colleges, it’s the biggest source of discouragement in continuing up of studies. I’m a Mathematics graduate myself and can speak of a proud mathematics tradition running in my family. I wasn’t an able torchbearer in the least of senses but I nevertheless tried my best. I never managed to master it, very few can boast of doing that but I was very respectful when it comes to scoring marks in it….always in the vicinity of 70% and never dropping below 60% throughout but this post isn’t about my tryst with Mathematics. It was someone else’s, a man who was said to be knowing ‘infinity’, a man who today is hailed as our national hero, a man who carried the name of Srinivas Ramanujan.

Ramanujan died aged only 32. He lived in Cambridge for 5 years prior to his demise. During his time there, he formed one of the most productive and influential partnerships in recent history of Mathematics with British superstar, G.H. Hardy. Hardy says that it was one’ romantic’ relationship of his life after learning of Ramanujan’s death and calls him the ‘most romantic figure’ of Mathematics development after 16th century. Professor Littlewood, a colleague, friend and supporter of both Hardy and Ramanujan told Hardy that ‘every positive integer is a personal friend of Ramanujan’ and that he should respect and be supportive of his ‘intuitive’ skills. Why and how could Hardy, an atheist and ‘apostle of proof’ get along with Ramanujan, a devout Hindu Tamil Brahmin and ‘prince of intuition’? It wasn’t certainly a cakewalk for either of them to forge this most ‘singular’ of mathematical partnership. Hardy and Ramanujan were both recluse but while Hardy took solace only in things that have real identities and can be proved of their existence (and since God’s can’t be proved, he didn’t believe in Him), for Ramanujan, no mathematical equation held a meaning if it didn’t express a thought of God. Hardy, when first received his letters from his port office of Madras, was in awe of all the startling theorems and identities that they enclosed. These theorems were entirely unproven but Hardy had no doubts that they aren’t real for he opined that if they are not, no one would have the imagination to think of them in first place. He consulted with Littlewood and arranged for Ramanujan to travel to England and meet him. Hardy couldn’t get along with him initially for Ramanujan was led to believe that once he reached England, Hardy would help him in getting his papers, inclusive of these astonishing theorems, published but Hardy needed proofs. One cannot discard the importance of theorems in Mathematics and here we are talking about Mathematics of highest order. One could not blame Hardy either for his ‘suppressed’ indifference toward Ramanujan’s unbelievable intuitive skills. He had no qualms in comparing Ramanujan to either Euler or Jacobi or even Newton in terms of possessing natural mathematical skills but he was the product and a ‘reluctant’ pioneer of an inelastic facilitating system in Cambridge and more precisely, Trinity College. He made Ramanujan to take elementary classes from professors much lesser in Mathematical ability as compared to him simply because he wanted him to be aware of ‘steps’ that could lead to a ‘logical’ conclusion to his theorems. Ramanujan flunked badly, many a times because of his precocious talent and other times, because he was a brown Indian, inhabitant of a British colony and how dare he could exhibit such talent that could only be reserved for white, elite Britishers? Hardy was aware of these socio-political issues himself and thus worked diligently on acquiring proofs for Ramanujan’s theorems. He was the person responsible for getting first ever paper published for Ramanujan from London Mathematical Society which dealt in ‘high composite numbers’. Ramanujan came along slowly but steadily and then went on to contribute heavily in fields of number theory, partitions, tau functions, hyper-geometric series etc. Hardy was right in every regard of Ramanujan. Well over a century later, Ramanujan’s explorations and divine intuition in numbers have found wide usage in fields of computer development, internet, statistical physics and black hole study. Every single theorem of his stood the test of the time and although mathematicians are still having a hard time in finding the proofs of his theorems, they all know they are searching for the ‘truth’ just like Hardy believed them to be. He continues to be an enigmatic figure for Mathematicians all over the world who draw inspiration from his humble beginnings and then his meteoric burst onto the center-stage of world mathematics among the giants of the fields such as Hardy, Bertrand Russell, Littlewood and Major MacMahon.

One of the modern mathematical giants, Ken Ono, an American-Japanese mathematician is a devotee of Ramanujan and has dedicated his life in deducing the proofs of Ramanujan’s theorems. His father, Takashi Ono is a distinguished professor of mathematics himself and wanted the young Ono to emulate him. Ken was a child prodigy but high cooker pressure environment of his growing up years compelled him to drop out of college and trod a path on his own. He somehow stumbled upon Ramanujan’s biography, the person whom his father adored and admired, and became so inspired that he not only decided to reconcile with his mathematician father but became a celebrated mathematician in his own regard. This year, he wrote his maiden book titled ‘My Search for Ramanujan: How I learned to Count’ where he has woven his life story with one of Ramanujan and the lessons he learned, the most important of them being ‘humanity’. Robert Kanigel, a mathematical engineer livening in America, has written the most authoritative biography of Ramanujan titled, ‘The Man Who Knew Infinity: A Life of the Genius Ramanujan’. It’s a seminal work of great science writing and one which became the basis of Matthew Brown’s 2015 film, The Man Who Knew Infinity starring Jeremy Irons as G.H. Hardy and Dev Patel as Srinivas Ramanujan. Many literary and mathematical associations including both American and English termed it as ‘arguably the best film about Mathematics ever made’ and I shall ask all of you to watch it if you care about this legendary mathematician and the subject interests you. It’s as good as ‘A Beautiful Mind’ and certainly well better than ‘The Imitation Game’ and ‘Good Will Hunting’ and I’m saying this not because of my growing reverence for Ramanujan which is obviously one of the reasons but also as it stands as a very fine motion picture on basis of cinematic standards alone.

Hardy, many years later when he grew acquaintance and a personal friend to Ramanujan, asked him, how he could possibly think of all these incredibly complex theorems out of nowhere and Ramanujan, knowing that Hardy is an atheist, resisted answering him. But when he was pressed beyond control, he told Hardy that his Goddess, Namagiri tells him everything when he is praying to her or in sleep. Hardy scarcely believed as expected of him but he knew as he always knew that Ramanujan was telling truth. Now the world believes him and his ‘divine intuitions’ are testaments to time. He surely knew ‘infinity’!!!

The Leftovers: A Very 'Special' HBO Production

Three things that have occupied my mind for last three days in descending order of importance are: Justin Trudeau, Heinrich Klassen and The Leftovers. I am going to write here about the least important entity for I am likely to forget about it most urgently. The Leftovers is an HBO production and like the most HBO productions, it makes for a great television experience. I chose to watch it for two reasons: First, it was only three season long with 28 episodes in total and secondly, for two years running, it was the best TV show in American Landscape. There was a third reason as well and it was in the name of its creator's promise. Damon Lindelof is one of the brightest American minds and he gave us 'Lost' all those years back. I have been a huge fan of 'Lost' and till this time, gush about its fantastical and mythical elements. People still find it very hard to crack the mysteries of Lost and when a show leaves you with more questions than the answers after its 8

Book Review: Unanswered

'Unanswered' is a book penned by Mr. Kunal Uniyal and it's his third book. I am calling it a book, using a common noun to describe it and I have a good enough reason for doing so. It's a book that consists off both poems and prose and I was in real dilemma picturing its prognosis in my mind. It started with a poem named 'You and I' and beautiful it was, all poised and lyrical. And then came a snippet of a prose by the name 'Life of a Yogi'. They were really not connected and I was perplexed. Then I allowed myself some comfort and decided to dig up some more. Some more beautiful poems and accompanying yet again not quite related passages of prose followed but now they looked more in shape and very much in order. Now I was beginning to realize that there was more to this book than met my eyes earlier and it's scope is much wider that what I originally thought. You are required to engage yourself with this book and once you do that, you will know you ar

Phillip Seymour Hoffman : An Obituary

Phillip Seymour Hoffman was one of the modern acting greats. You can always identify and isolate him in an ensemble cast. Give him just two-three lines in a 150-180 minutes long feature film and still he would enthrall the audience with his magic and aura and come out on top. People and critics alike bestowed countless superlatives upon him in a career spanning over more than two decades but whether any one of those adjectives ever managed to justify his cinematic craft, I seriously doubted. He was unprecedented and unsurpassed in the practice of cinematic artistry and thus emerged as America’s greatest character actor ever, period. Paul Giamatti is his worthy successor and hopefully he would calm and soothe our nerves with his finest performances in times to come in Phillip’s absence. Phillip ultimately was a show-stealer, a rabble-rouser, an aloof but a sympathizing marvelous human being who marveled in Hollywood though always residing at its sidelines. I first saw him playing a y
