Answer: (A) S. Ramanujan

Answer: (a) S. Ramanujan

'The Man Who Knew Infinity' is a 2015 biographical film based on the book by Robert Kanigel about the legendary Indian mathematician Srinivasa Ramanujan (1887-1920).

About Ramanujan:

  • Self-taught genius from Tamil Nadu
  • Made extraordinary contributions to number theory and infinite series
  • Went to Cambridge to work with mathematician G.H. Hardy
  • Produced nearly 3,900 results
  • Died young at 32

The film starred Dev Patel as Ramanujan and was screened at the 46th IFFI.

Why not the others? (b) S. Chandrasekhar - Nobel laureate in Physics; no movie by this name.
(c) S.N. Bose - Famous for Bose-Einstein statistics; no such movie.
(d) C.V. Raman - Nobel laureate for Raman Effect; no such movie.

Why this was asked

The Man Who Knew Infinity is a 2015 biographical film about mathematician Srinivasa Ramanujan, released around the time of this 2016 UPSC exam.

Ramanujan was a self-taught mathematical genius from Tamil Nadu who made groundbreaking contributions to number theory despite having no formal training in pure mathematics.

Srinivasa Ramanujan: The Self-Taught Mathematical Genius

Must know

Self-taught mathematician from Tamil Nadu who made extraordinary contributions to number theory and infinite series

Collaborated with G.H. Hardy at Cambridge University and produced nearly 3,900 mathematical results

Subject of the 2015 biographical film 'The Man Who Knew Infinity' starring Dev Patel

Good to know

Lived from 1887-1920, died young at age 32

Mathematical Legacy

Srinivasa Ramanujan (1887-1920) was a self-taught mathematical prodigy from Erode, Tamil Nadu. Despite having no formal training in pure mathematics, he independently rediscovered centuries of Western mathematics and made groundbreaking contributions to number theory, infinite series, and continued fractions.

• His work on partition functions and mock theta functions opened entirely new areas of research
• Developed the Hardy-Ramanujan asymptotic formula for partition numbers
• His notebooks contained thousands of theorems, many proven decades later

Cambridge Period & Recognition

Invited to Cambridge University in 1914 by mathematician G.H. Hardy after correspondence

Became a Fellow of the Royal Society in 1918 - second Indian to receive this honor

Produced nearly 3,900 results during his brief career, most without rigorous proofs

His intuitive approach to mathematics amazed Western mathematicians of his time

Returned to India in 1919 due to poor health and died within a year

Exam traps

Don't confuse with S. Chandrasekhar (Nobel Prize Physics, black hole theory) or C.V. Raman (Nobel Prize Physics, Raman Effect)

The film title 'The Man Who Knew Infinity' refers to his work on infinite series, not general knowledge

Ramanujan worked on pure mathematics (number theory), not applied physics like the other options

He was self-taught - never had formal mathematical education unlike university-trained scientists

Collaborated with Albert Einstein on quantum mechanics of particles

Bosons (fundamental particles) are named after him

Never won Nobel Prize despite groundbreaking contributions to quantum physics

His work laid foundation for Bose-Einstein condensate research

Exam traps

Chandrasekhar vs Chandrashekar - mind the spelling in options

Don't assume all famous Indian scientists won Nobel Prizes - S.N. Bose never did

Raman Effect (C.V. Raman) vs Rayleigh scattering - different light scattering phenomena

Chandrasekhar worked on stars and black holes, not mathematics like Ramanujan

'The Man Who Knew Infinity' (2015) - biographical film on S. Ramanujan starring Dev Patel

Good to know

Based on the book by Robert Kanigel about Ramanujan's life and work at Cambridge

Screened at 46th International Film Festival of India (IFFI)

Film Details & Cultural Impact

'The Man Who Knew Infinity' brought the story of India's mathematical genius to global audiences. The film depicts Ramanujan's journey from poverty in colonial India to Cambridge University, highlighting both his mathematical brilliance and the cultural challenges he faced.

• Starred Dev Patel as Ramanujan and Jeremy Irons as G.H. Hardy
• Focused on the mentor-student relationship between Hardy and Ramanujan
• Showcased the clash between intuitive Eastern and rigorous Western approaches to mathematics

Other Science Biopics in Indian Context

Mission Mangal (2019) - dramatized account of India's Mars Orbiter Mission

Rocket Boys (2022 web series) - biographical series on Homi Bhabha and Vikram Sarabhai

The Theory of Everything (2014) - Stephen Hawking biopic, relevant for physics awareness

Growing trend of STEM-focused cinema highlighting scientific achievements

Such films help popularize science and inspire young students toward research

Exam traps

Film title references 'infinity' because of Ramanujan's work on infinite series, not general knowledge

Don't confuse with other mathematician biopics like 'A Beautiful Mind' (John Nash)

The film was made in 2015 but may appear in questions about recent cultural productions

IFFI screening connects the film to Indian cultural institutions, making it UPSC-relevant
