A self-taught math whiz from India bamboozles stuffy British professors with numbers that pop into his head, proving that intuition is basically just cheating at math.
🍿 The Man Who Knew Infinity: Detailed Plot Synopsis
Early Life in Madras
Set in the 1910s, the film introduces Srinivasa Ramanujan, a brilliant but impoverished self-taught mathematician living in Madras, India. Despite facing financial hardships, his exceptional intellect shines through as he develops groundbreaking mathematical theories. He marries Janaki, but his dedication to mathematics consumes him.

Invitation to Cambridge
Ramanujan’s work catches the eye of G.H. Hardy, a renowned mathematics professor at Trinity College, Cambridge. Hardy recognizes Ramanujan’s raw genius and invites him to England to further his studies. Reluctantly, Ramanujan leaves his wife and family to pursue this opportunity, embarking on a journey to a foreign land filled with both promise and challenges.

Clash of Cultures and Ideologies
At Cambridge, Ramanujan faces a starkly different academic environment and cultural prejudices. His intuitive approach to mathematics clashes with Hardy’s insistence on rigorous proof. While Hardy champions Ramanujan’s talent, he also pushes him to adapt to the established norms of the British academic world. This creates tension between the two, as Ramanujan struggles to balance his faith, his cultural identity, and his pursuit of mathematical excellence.

World War I and Personal Struggles
The backdrop of World War I adds further strain as resources dwindle and anti-Indian sentiments rise. Ramanujan battles homesickness, struggles with the unfamiliar cuisine, and faces health issues due to the harsh English climate. He is determined to validate his work while coping with increasing personal and professional obstacles. His relationship with Hardy deepens as they navigate these challenges together.
