**National Mathematics Day 2021: This day is celebrated annually in India to mark the birth anniversary of the talented mathematician Srinivasa Ramanujan. In 2012, former Prime Minister Manmohan Singh declared 22 December as National Mathematics Day to honor the talented mathematician.**

The main objective of celebrating this day as National Mathematics Day is to create awareness among the people about the importance of Mathematics. He had already given 3500 mathematical formulas to the world before he died at the age of 32.

Srinivasa Ramanujan, also known as ‘the man of infinity’, did not receive any formal training in mathematics. However, nevertheless, he made substantial contributions to mathematical analysis, number theory, infinite series and continued fractions, including solutions to mathematical problems.

According to Hans Eysenck, “he tried to get leading professional mathematicians interested in his work but was unsuccessful for the most part. What he had to show was too novel, too unfamiliar, and additionally presented in unusual ways.” they could not be disturbed”.

Several programs are organized in schools and colleges to commemorate his birth anniversary. As the day approaches, here we bring you some interesting facts about Srinivasa Ramanujan.

After a funny incident, the number ‘Hardy-Ramanujam’ was coined in his honor in 1729, and such numbers are called taxicab numbers.

At the age of thirteen, he did Loni’s trigonometry exercise without any help.

Ramanujan wrote 17 ways to represent 1/pi as an infinite series. Esper Britannica, in his notebook, he elaborated something a bit more than 1/pi became faster: 1/pi = (sqrt(8)/9801) * (1103 + 659832/24591257856 +…).

He was the second Indian in 1918 to be inducted as a Fellow of the Royal Society, a fellowship of some of the world’s most distinguished scientists.

He is the first Indian Fellow of Trinity College, Cambridge.
