Once Dr. BR Ambedkar said, “Life should be Great rather than long,” and this quote fits for a great Mathematician personality Srinivas Ramanujan. Born in a Brhaman family of British ruled South India’s Madras Presidency, Ramanujan became the pride of India by proving his extraordinary Mathematical capabilities at time when the country was considered as uncivilized and static. Ramanuijan died at a very young age of 32 but mathematics is still keeping him alive through his work.According to Ramanujan’s biographer,when he was in 7th class, he started teaching maths to students pursuing graduation and even his teachers did not have the answers for his queries. The mathematician used to say that Discovering Math is similar to discovering God.
Ramanujan got adimission in high school in 1898 and this was also the time when he got to study mathematician GS Car’s book called, “A synopsis of elemenatry results in pure and applied Mathematics”, the book consisted 5000 formulas of higher Mathematics and Ramanujan solved all of them. After high school Ramanujan got scholarship but just because he was only interested in Mathematics and failed in other except english and maths his scholarship was taken away from him. After that in 1909 Ramanujan got married and started looking for a job. Finally he got a job in Indian Mathematical Society where he used to Create questions and there answer for the Journal, the salary paid to him was 25 Rs. per month. His job at Indian Mathematical society became the trajectory for his upcoming life as it was the place where he met all the important personalities of Mathematics.
His work got appreciation in 1911 after publication of his academic work on Burnolie numbers. In 1912 with the help of Ramachandra Rao he got another job as clerk in Madras Port Trust. Meanwhile he continued his work on Mathematics. In 1913 along with a list of his Formulas, Ramanujan sent a letter to Cambridge University professor GH Hardy. Initially professor took all the formulas and his letter as a big lie, but when he briefly examined them, he found them new and unimaginary. He called Ramanujan to Cambridge which can be considered as a start of new era for the study of Mathematics. Ramanujan has learnt Mathematics on his own which has made him unaware about developments by other mathematicians, GH Hardy taught him everything that Ramanujan was unaware of, but at last GH Hardy said,”What I teach Ramanujan is nothing in comparison of what Ramanujan taught me.” In 1916 when Ramanujan got degree in BSC his work with Hardy started acknowledgement throughout the world.
The number 1729 is known as the Hardy–Ramanujan number after a famous visit by Hardy to see Ramanujan at a hospital. In Hardy’s words:
I remember once going to see him when he was ill at Putney. I had ridden in taxi cab number 1729 and remarked that the number seemed to me rather a dull one, and that I hoped it was not an unfavorable omen. “No”, he replied, “it is a very interesting number; it is the smallest number expressible as the sum of two cubes in two different ways.”
Ramanujan proposed an abundance of formulae that could be investigated later in depth. G. H. Hardy said that Ramanujan’s discoveries are unusually rich and that there is often more to them than initially meets the eye. As a byproduct of his work, new directions of research were opened up. Examples of the most interesting of these formulae include the intriguing infinite series for π.
Throughout his life, Ramanujan was plagued by health problems. His health worsened in England; possibly he was also less resilient due to the difficulty of keeping to the strict dietary requirements of his religion in England and wartime rationing during 1914–1918. He was diagnosed with tuberculosis and a severe vitamin deficiency at the time, and was confined to a sanatorium. In 1919 he returned to Kumbakonam, Madras Presidency, and soon thereafter, in 1920, died at the age of 32.
