    A Tragic Genius: Early Life and Mathematical Awakening

    In The Man Who Knew Infinity: Robert Kanigel unveils the life story of Srinivasa Ramanujan, an Indian mathematician who made monumental contributions to the field of theoretical mathematics. Ramanujan, born into a humble family in the town of Kumbakonam, exhibited exceptional mathematical prowess from an early age. Despite severe economic deprivation and absence of formal guidance, Ramanujan's intellectual curiosity drove him to explore the intricacies and complexities of numbers.

    Through self-taught knowledge, he began to re-derive known algebraic theorems and stumbled upon his own theorems as a teenager. His exceptional abilities didn't escape the notice of his teachers and fellow students, propelling him to a scholarship at the Government College in his hometown.

    The Struggles and the Breakthrough Letter

    As much as Ramanujan’s academic journey was marked by astounding mathematical discoveries, it was also beset by financial hardship and the displayer of traditional academic norms. His obsessive concentration on mathematics was to the detriment of other subjects, causing him to lose his scholarship. However, recognizing his extraordinary talent, V. Ramaswamy Iyer, the founder of the Indian Mathematical Society, employed Ramanujan as a clerk and provided him with books and an environment conducive to research.

    Years later, desperate to reach a wider audience and seek validation for his work, Ramanujan wrote a letter to G. H. Hardy, a renowned mathematician at the University of Cambridge. This letter, filled with baffling theorems without detailed proofs, managed to pique the interest of Hardy, who recognised Ramanujan’s latent genius and invited him to Cambridge.

    East Meets West: Collaboration and Contribution to Mathematics

    Despite initial cultural shock and health issues attributed to the English weather and dietary restrictions due to his devout Hindu faith, Ramanujan thrived under Hardy’s mentorship. Their close collaboration led to significant contributions to areas of partitions, q-series, and the approximation of π. Ramanujan's work was characterized by a blend of intuition and complex calculations, which often left Hardy perplexed but enchanted.

    Ramanujan went on to become the first Indian to be elected a Fellow of Trinity College, Cambridge. However, his health dramatically deteriorated, forcing him to return to India in 1919, where he died at the young age of 32. Even in his last days, he continued to embrace his passion, discussing his unpublished results and jotting down enigmatic formulas which continue to be a topic of investigation.

    Eternal Legacy of Ramanujan: Infinity and Beyond

    In Kanigel's bioepic The Man Who Knew Infinity, Ramanujan is presented as a mystic mathematician bridging the world of theoretical mathematics with the spiritual realm. Most of his theorems were results of intuitive leaps, bereft of traditional methods of attaining proofs, often credited to his family deity, Goddess Mahalakshmi of Namakkal.

    In conclusion, Ramanujan’s chronicled journey from a clerk in Madras to a celebrated mathematician in Cambridge is as awe-inspiring as his intriguing mathematical theorems. His remarkable contributions to the field of mathematics, done under challenging circumstances and limited lifespan, reaffirmed the power of raw talent, passion and intuition. His life and work continue to inspire mathematicians today, immortalizing 'The Man Who Knew Infinity' in the annals of history.
