**HISTORY**

National Mathematics Day is celebrated on 22 December every year to mark the birth anniversary of legendary Indian mathematician, Srinivasa Ramanujan and his contributions in the field of mathematics.

On 22 December 2012, the former Prime Minister of India, Dr. Manmohan Singh, paid tribute to Srinivasa Ramanujan at a function organised on the occasion of the 125th birth anniversary of the great mathematician Srinivasa Iyengar Ramanujan in Chennai. 22 December was declared as National Mathematics Day. Thus, on 22 December 2012, National Mathematics Day was celebrated across the country for the first time.

**Contributions of Ramanujan in Mathematics**

Ramanujan’s genius has been regarded by mathematicians to be at par with Euler and Jacobi from the 18th and 19th centuries, respectively. His work in the number theory is especially regarded, and he made advances in the partition function. Ramanujan was recognised for his mastery of continued fractions, and had worked out the Riemann series, elliptic integrals, hypergeometric series, and the functional equations of the zeta function. After his death, Ramanujan left behind three notebooks and some pages containing unpublished results, on which mathematicians continued to work on for many years.

The Dev Patel-starrer ‘The Man Who Knew Infinity’ (2015) was a biopic on the mathematician.
