In India, the National Mathematics Day is observed on December 22 every year. It is celebrated in order to honor the birth anniversary of the famous mathematician Sir Srinivasa Ramanujan. He was a world-famous mathematician who made remarkable contributions in different fields and branches of the subject of mathematics.
Who was Srinivasa Ramanujan?
Srinivasa Ramanujan was born on 22 December, 1887, in a Tamil Brahmin family in the city of Erode. He was known as ‘The Man Who Knew Infinity’ because of his infinite love for and contribution to mathematics. Initially, he read mathematics voraciously and started developing his own research in isolation in the beginning. Srinivasa was an autodidact; he was a self-taught person and never had any formal training in mathematics. He first solved the formal and regular mathematics when he was 10 years old. When he was at the school, he received several merit certificates and academic awards.

The mathematical genius could easily solve algebra and trigonometric problem which his fellow mates found difficult to crack. Ramanujan has greatly contributed towards mathematical analysis, number theory, infinite series and continued fractions. In the year 1913, Srinivasa Ramanujan came in contact with the European mathematicians for further developing his knowledge and interest towards mathematics. He was also elected to various societies organized for the debate and discussion on mathematics. He started exchanging letters with the world famous mathematician G. H. Hardy and ultimately moved to England in the year 1914. He spent around 5 years at Cambridge and issued a number of papers during his stay there.
Significance of National Mathematics Day:
For his memorable and great contributions towards mathematics, the birth anniversary of Srinivasa Ramanujan was declared as the National Mathematics Day in the year 2012 by the then Prime Minister of India Dr. Manmohan Singh. The year 2012 was celebrated as the National Mathematics Year across the country India for the first time.
National Mathematics Day is celebrated in India for paying tribute to the great mathematicians of India. The great Indian mathematicians such as Brahmagupta, Aryabhata, and Srinivasa Ramanujan have played a significant role in developing different formulas, theorems and theories on mathematics in India. And thus, it is important to promote and cultivate the magnificent tradition of Indian mathematics by celebrating National Mathematics Day.
