Ramanujam FRS Mathematician

Sam (Chennai, India) on 22 December 2012 in People & Portrait and Portfolio.

Srinivasan Ramanujam FRS (22 December 1887 – 26 April 1920) was an Indian Mathematician and autodidact who, with almost no formal training in pure mathematics, made extraordinary contributions to mathematical analysis, number theory, infinite series, and continued fractions. Ramanujan was said to be a natural genius by the English mathematician G.H. Hardy, in the same league as mathematicians like Euler and Gauss.

Born in a poor family, Ramanujan's introduction to formal mathematics began at age 10. He demonstrated a natural ability, and was given books on advanced trigonometry written by S. L. Loney that he mastered by the age of 12; he even discovered theorems of his own, and re-discovered Euler's identity independently. He demonstrated unusual mathematical skills at school, winning accolades and awards. By 17, Ramanujan had conducted his own mathematical research on Bernoulli numbers and the Euler–Mascheroni constant.

G. H. Hardy, recognizing the brilliance of his work, invited Ramanujan to visit and work with him at Cambridge. He became a Fellow of the Royal Society and a Fellow of Trinity College, Cambridge. Ramanujan died of illness, in 1920 at the age of 32.

During his short lifetime, Ramanujan independently compiled nearly 3900 results (mostly identities and equations). Nearly all his claims have now been proven correct, although a small number of these results were already known. He stated results that were both original and highly unconventional, such as the Ramanujan prime and the Ramanujan theta function, and these have inspired a vast amount of further research. However, the mathematical mainstream has been rather slow in absorbing some of his major discoveries. The Ramanujan Journal, an international publication, was launched to publish work in all areas of mathematics influenced by his work.

In December 2011, in recognition of his contribution to mathematics, the Government of India declared that Ramanujan's birthday should be celebrated every year as National Mathematics Day, and also declared 2012 the National Mathematical Year.

We are proud and happy to remember the contribution of Ramanujam the great Mathematician and genius and pay our tributes to this Genius on this National Mathematics Day.

A wonderful tribute to this genius who alas had to leave the world so soon.
You have posted a lot of information here for those who may not have heard about him.I have read somewhere that he was very spiritual and that Lord Narasimha Himself would aid him in his mathematical doubts!!!
Thank you Sam for posting this wonderful portrait and all about him.
