Sir Srinivas Ramanujan - The Immortal Genius

The man who made India proud without a formal educational qualification and stunned the world's top scientists, engineers and thinkers during British era is called Ramanujan.
He was born in Erode, Madras Presidency (Now its in Tamil Nadu state) on December 22, 1887. This was misfortune for Mathematics, India and the world that Ramanujan didn't live longer but died at very young age of 32 on 26 April 1920.

Very short life and immense contributions world is proud of.

Contributions in Mathematics earned him Fellowship of Royal Society.

Here is link to his thesis in Mathematics Highly Composite Numbers

He is known for

  • Landau–Ramanujan constant
  • Mock theta functions
  • Ramanujan conjecture
  • Ramanujan prime
  • Ramanujan–Soldner constant
  • Ramanujan theta function
  • Ramanujan's sum
  • Rogers–Ramanujan identities
  • Ramanujan's master theorem
Ramanujan earned his B.Sc degree from Trinity College, Cambridge in 1916.

Ramanujan was influenced by work of British Mathematician GS Carr, Synopsis of Pure Mathematics (1886). He was the coach for the Tripos Mathematics Examination and book was a study guide.
Ramanujan was a young teen boy then and by the time he has already produced many theorems of his own. The work of GS Carr made significant impact in his curious mind.

It was Mathematician GH Hardy in Cambridge who recognized genius in  Ramanujan. In 1913, Ramanujan send some of his mathematical theorems to GH Hardy in Cambridge, UK. Further, recognizing the potential of Ramanujan, GH Hardy arranged for his travel to UK admission in Trinity College Cambridge.

GH Hardy and JE Littlewood was academic advisor to Ramanujan in Cambridge for his research work.
