✡ *About Srinivasa Ramanujan and his contributions in Mathematics*

◆Srinivasa Ramanujan was born on 22 December, 1887, Erode, India and died on 26 April, 1920 at Kumbakonam.At the age of 12, he had gained knowledge in Trignometry and without anyone's help, he had developed his own theorems and ideas.

◆He had spent his childhood days in great difficulty in poverty. He used to borrow books and read books from friends in school.

◆When he was young, he took up the job of clerk to meet the economic needs of the house, and when he gets the time he used to solve mathematics questions and worked on various types of theorems.

◆Once, an Englishman saw those pages,he was impressed and took a personal interest. He sends Srinivasa Ramanujan to the Hardy, the Professor of Oxford University.

◆He then recognized the talent hidden in him and thereafter he got fame worldwide.

◆His papers were published in the Journal of the Indian Mathematical society in 1911.

◆He had compiled about 3900 results mainly identities and equations that too on his own without anyone's assistance. Several results out of them are original and novel like the Ramanujan prime, The Ramanujan theta function, partition formulae and mock theta functions. These results further inspired several other research and opened new fields of work.

◆He discovered his own theory of divergent series, worked out the Riemann series, the elliptic integrals, hyper geometric series and the functional equations of the zeta function.

●Let us tell you that the number 1729 is known as the Hardy-Ramanujan number.

●So now we come to know that National Mathematics Day is celebrated on 22 December every year to spread awareness about the importance of mathematics and the contributions made by the scholar of mathematics Srinivasa Ramanujan.

◆The government of India decided in 2012 to celebrate National Mathematics Day on 22 December on the birth anniversary of Srinivasa Ramanujan.

◆Since then it was celebrated on 22 December every year.
