National Mathematics Day-Top 10 facts about S Ramanujan

 22 December - National Mathematics Day

National Mathematics Day is celebrated on 22 December annually to commemorate the birth anniversary of the famous mathematician Srinivasa Ramanujan. He had made remarkable contributions in various fields of mathematics and its branches. He was born on 22 December 1887 in Erode (today in the city of Tamil Nadu).

S Ramanujan: Srinivasa Ramanujan was a self-taught mathematician who contributed to the theory of numbers. Born in Erode, Tamil Nadu, in 1887, Ramanujan grew up in poverty, his father working as an accounting clerk, while his mother earning a small amount as a temple singer. The mathematician died on April 26, 1920.

Ramanujan had contracted tuberculosis in 1919 and died of the diseases in 1920.

Here are 10 facts about the mathematics genius.

Top 10 facts about S Ramanujan

1. At the age of 15, Srinivasa Ramanujan obtained a copy of Synopsis on Elementary Results in Pure and Applied Mathematics, which contained 5,000 theorems but had either brief proofs or did not have any. C Ramanujan then took to solving each of the theorems, eventually succeeding.
   Ramanujan had obtained a scholarship for the University of Madras, but he ended up losing it because he neglected his studies in other subjects in favour of mathematics.
2. Srinivasa was in such poverty that he often sustained on minimal foods and did not even have enough money to obtain paper for his studies. As a result, he used slates for his mathematics and cleaned them with his elbow, leading to bruises and marks.
3. Even with little formal training in mathematics, Ramanujan published his first paper in the Journal of Indian Mathematical Society in 1911.
4. In 1913, Ramanujan started communicating with Godfrey H Hardy, a British mathematician. This led him to obtain a scholarship from the University of Madras and a grant from Trinity College in Cambridge, after which he travelled to England and started to work on some research with Hardy.
5. Even as Ramanujan did not have much knowledge about modern mathematics due to no formal guidance, no living mathematician equalled in his knowledge of continued fractions.
6. After his advances, especially in the field of the partition of numbers, and the publication of his papers in several English as well as European journals, he was elected to the Royal Society of London in 1918.
7. Ramanujan was a sensitive person. He had once invited a friend and the friend’s fiancee to dinner while he was in Cambridge. However, when his friend and fiancee, full from eating Rasam, declined the next serving, Ramanujan vanished from the house without informing his friends.
8. When he returned four days later, he admitted to his friends that his feelings were hurt when his friends denied the serving.
9. After contracting tuberculosis, the mathematician recovered enough in 1919 to return to India, but died the following year, without much recognition. However, the mathematics community recognised him as a genius without peer.
10. The genius mathematician left as his legacy three notebooks and a huge bundle of pages, which contained unpublished result which was being verified by mathematicians many years after his death.
