Answer:
Srinivasa Ramanujan is one of the greatest mathematicians in the world, and he is known for the great work that he did in his field. He made a lot of his theories very popular in the world, and that is why his theories still get used in lots of countries.
He was born on 22nd December 1887 in Erode, and he gets known by a number of contributions he made in the theory of numbers. It is very shocking for a lot of people, but initially, Ramanujan never studied mathematics. He studied mathematics in the latter half of his education and became an expert of it.
He studied a few books written by international mathematicians, and after a few years, he made his own several theories on mathematics.
He was very poor, and he did various researches in poor circumstances only, but he later got supported by Ramachandra Rao and his clerical job due to which he became able to learn more and invent several new studies on mathematics.
In 1914, he won a scholarship to England and studied under Godfrey hardy. He did not only studied hard but invented various other theories which made Hardy his fan as well. He surprised every teacher with the knowledge of mathematics that he had because he never knew the modern techniques of the maths, but he still did better than a lot of professors and researchers at that time.
He invented a lot of theories, and the most famous ones are as followed: Ramanujan constant, Mock theta functions, Ramanujan conjecture, Ramanujan prime, Ramanujan theta function, Ramanujan’s sum, Ramanujan’s seta series, etc. He also won the award of fellow of the royal society.
He worked for a very short period as he died at the age of 32 only, but his theories are still alive in a lot of people’s brains and textbooks. So, this was all about the best mathematician in the country Srinivasa Ramanujan.
His exceptional genius in mathematics had already been acknowledged while in Cambridge, and his work still lives on to make every Indian proud.
Contribution:
In 1904 Ramanujan provided a method to calculate Bernoulli numbers and calculated the Euler–Mascheroni constant up to 15 decimal places.
He was also awarded by the K. Ranganatha Rao prize from school Headmaster.
Founded The Indian Mathematical Society.
He solved the problems to find the values of differential
Hardy–Ramanujan number 1729 is also his famous work.
