The turning point in Ramanujan's life came when he sent a letter to Cambridge professor G.H. Hardy, accompanied by a set of his mathematical results. Hardy's initial skepticism gave way to amazement as he realized the depth and originality of Ramanujan's work. Recognizing the genius of the young Indian mathematician, Hardy invited Ramanujan to Cambridge, where he would collaborate with some of the greatest minds in mathematics.
Born in 1887 in a small town in Tamil Nadu, India, Ramanujan was a prodigy whose talent emerged despite extreme poverty and a lack of formal higher education.
Ramanujan suffered terribly in cold, wartime England. He was homesick, struggled with the strict European diet, and eventually contracted tuberculosis and severe vitamin deficiencies. He returned to India in 1919 and died the following year at age 32 . the man who knew infinity
Here’s a helpful, concise breakdown of what makes the book (and Ramanujan’s story) so remarkable:
Their relationship drives the emotional core of the film. It begins as a clash of epistemologies: Hardy demands rigorous, linear proof for every assertion, while Ramanujan operates on intuition, presenting results that he cannot always explain but knows to be true. The tension is palpable—Hardy represents the Western tradition of logic and structure, while Ramanujan represents an Eastern, holistic approach where faith and mathematics are intertwined. Over time, however, this tension evolves into a symbiotic respect. Hardy becomes not just a mentor, but a savior, protecting Ramanujan from the virulent racism of the British establishment and the isolation of a country at war. The turning point in Ramanujan's life came when
His "lost notebook" (discovered in 1976) contained formulas later used to study black holes and particle physics. His work continues to inspire new mathematics today.
Perhaps the film’s most poignant theme is the tragic cost of discovery. Ramanujan’s time in England is a slow deterioration. The cold climate, the scarcity of food due to the war, and the stress of constant scrutiny ravage his health. The film does not shy away from the reality that great leaps in human understanding often require great personal sacrifice. There is a heartbreaking irony in the fact that while Ramanujan is unlocking the secrets of the infinite, his own physical existence is fading away. The visuals reflect this duality; the mathematics displayed on screen—complex partitions and mock theta functions—are beautiful and eternal, while the man writing them is fragile and mortal. Recognizing the genius of the young Indian mathematician,

"An equation for me has no meaning unless it expresses a thought of God." — Ramanujan (as portrayed by Kanigel)
The 2015 biographical drama The Man Who Knew Infinity , based on Robert Kanigel’s 1991 biography, is far more than a standard depiction of a mathematical prodigy. It is a profound meditation on the nature of genius, the collision of cultures, and the redemptive power of friendship. Through the life of Srinivasa Ramanujan, the film explores a central, haunting question: does talent belong to the individual, or is it a universal force that transcends race, class, and education?
