Srinivasa Iyengar Ramanujan, popularly known as S. Ramanujan, was amongst the most renowned and respected mathematicians in India
. He is credited with making numerous significant contributions to various fields of mathematics. This great mathematician was a self-taught learner and had no formal education
in pure mathematics. He had made astonishing contributions to number theory, continued fractions, mathematical analysis and infinite series. Ramanujan is generally considered as one of the soaring geniuses in mathematics.
Early Life of Srinivasa Ramanujan
Srinivasa Iyengar Ramanujan was born on 22nd of December, 1887 in Erode
, Tamil Nadu
. He struggled with poverty during his childhood days. However he was talented in mathematics. Ramanujan failed to complete his formal studies after Matriculation, due to his lack of attendance to the subjects other than mathematics. He failed twice in the Fine Arts
degree exam. Once his formal education was over, he had to face a lot of difficulties in earning his livelihood. He actively started searching for jobs, after his marriage
with Janaki. However, he had to wait for 5 long years before getting a job, as he did not have any formal educational certificate with him.
Career of Srinivasa Ramanujan
While pursuing for job, Srinivasa Iyengar Ramanujan travelled extensively to Chennai
and the neighbouring towns and during this course; he met several mathematicians who became his friends. R. Ramchandra Rao, the Collector of Nellore
soon granted S. Ramanujan a good scholarship of Rs 25 per month from his personal funds so that Ramanujan could pursue his passion for mathematics without even having a job. He also arranged a job for him and Ramanujan soon joined in a clerical post in the Madras Port Trust. He was a Class III-Grade-IV Clerk. Apart from studying mathematics, Ramanujan also started contributing research papers in the newly started Journal of the Indian Mathematical Society.
The turning point in Ramanujans life occurred when he got the chance to go to England and pursue systematic studies in higher mathematics. Apart from that, Srinivasa Iyengar Ramanujan also got a fellowship in the University of Madras
for pursuing research in mathematics, in spite of lacking formal education.
Achievements of Srinivasa Ramanujan
Srinivasa Iyengar Ramanujan was awarded a B.A. degree in March 1916 for his job on highly composite numbers that was published as a paper in the Journal of the London Mathematical Society. He was elected to the London Mathematical Society on 6th December 1917. He was also elected a Fellow of the Royal Society in 1918 for his investigation in Elliptic Functions and the Theory of Numbers. He was the second Indian to become a Fellow and also one of the youngest Fellows in the entire history of the Royal Society. Ramanujan also became the first Indian to be elected a Fellow of Trinity College, Cambridge for his contribution in developing the Number Theory, on 13th of October, 1918.
Contributions of Srinivasa Ramanujan
The chief contribution of Ramanujan in mathematics lies mainly in analysis, game theory and infinite series. He made in depth analysis in order to solve various mathematical problems by bringing to light new and novel ideas that gave impetus to progress of game theory.
Ramanujan was diagnosed with tuberculosis
and a severe vitamin deficiency and was confined to a hospital. After suffering from various diseases for some months, Srinivasa Iyengar Ramanujan eventually came back to India but unfortunately, he died at the young age of 32 years on 26th of April, 1920.
The Government of India
has issued a commemorative stamp to pay tribute and honour the 75th Birth Anniversary of Srinivasa Iyengar Ramanujan in 1962. Tamil Nadu celebrates his birthday as the State IT Day. The Ramanujan Journal was launched as an international publication, which included his work in areas of mathematics.
