About Ramanujan

 

                            The Hardy-Ramanujan number = 1729

 Sir Srinivasa Ramanujam
 (1887 – 1920):
Great Indian Mathematician, whose interest from academics at Trinity, College, Cambridge, led him to collaborate there and postulate and prove well over 3,542 theorems

Ramanujan was among greatest mathematical geniuses. He made substantial contributions to the analytical theory of numbers and worked on elliptic functions, continued fractions, and infinite series. 

Born in poor family in pre-independent India, Ramanujan discovers the power of number theory. He gave many theorems & proofs, some of  them are still problem to present mathematicians. 

Srīnivāsa Aiyangār Rāmānujan FRS, known as Srinivasa Iyengar Ramanujan (22 December 1887  – 26 April 1920) was an Indian mathematician who, with almost no formal training in pure mathematics, made substantial contributions to mathematical analysis, number theory, infinite series and continued fractions.

Born and raised in Erode, Tamil Nadu, India, Ramanujan first encountered formal mathematics at age 10. He demonstrated a natural ability, and was given books on advanced trigonometry written by S L Loney. He had mastered them by age 12, and even discovered theorems of his own. He demonstrated unusual mathematical skills at school, winning accolades and awards. By 17, Ramanujan conducted his own mathematical research on Bernoulli numbers and the Euler–Mascheroni constant.

He received a scholarship to study at Government College in Kumbakonam, but lost it when he failed his non-mathematical coursework. He joined another college to pursue independent mathematical research, working as a clerk in the Accountant-General's office at the Madras Port Trust Office to support himself.

In 1912–1913, he sent samples of his theorems to three academics at the University of Cambridge. Only G. H. Hardy recognized the brilliance of his work, subsequently inviting Ramanujan to visit and work with him at Cambridge. He became a Fellow of the Royal Society and a Fellow of Trinity College, Cambridge, dying of illness, malnutrition and possibly liver infection in 1920 at the age of 32.
