National Mathematics Day:

Topics Covered: Achievements of Indians in science & technology;

Context:

Celebrated every year on December 22.

It is observed to honor the birth anniversary of the famous mathematician Srinivasa Ramanujan who greatly contributed towards mathematical analysis, number theory, infinite series and continued fractions.
2021 marks 134th birth anniversary of Dr Ramanujan.

Highlights of Srinivasa Ramanujan’s life:

In 1911, Ramanujan published the first of his papers in the Journal of the Indian Mathematical Society.
Ramanujan traveled to England in 1914, where Hardy tutored him and collaborated with him in some research.
He worked out the Riemann series, the elliptic integrals, hypergeometric series, the functional equations of the zeta function, and his own theory of divergent series.
The number 1729 is known as the Hardy-Ramanujan number after a famous visit by Hardy to see Ramanujan at a hospital. It is the smallest number which can be expressed as the sum of two different cubes in two different ways.
Hardy observed Ramanujan’s work primarily involved fields less known even amongst other pure mathematicians.
Ramanujan’s home state of Tamil Nadu celebrates 22 December as ‘State IT Day’, memorialising both the man and his achievements, as a native of Tamil Nadu.
Ramanujan compiled around 3,900 results consisting of equations and identities. One of his most treasured findings was his infinite series for

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