Srinivasa Ramanujan was born on 22nd December 1887 in Erode, Tamil Nadu and died on 26th April 1920 at the age of 32 years. He was an Indian mathematician who became the second Indian member in Fellows of the Royal Society.
Ramanujan initially developed his own mathematical research in isolation. In 1913, Ramanujan sent his theories and solutions by post to G.H. Hardy, Cambridge University, England. Their relationship continued by postal department.
Ramanujan sent his extraordinary work as samples. Hardy arranged travel to Cambridge. He is the first Indian to be elected in Fellow of Trinity College, Cambridge. Ramanujan had produced ground breaking new theorems and those are recently proven but highly advanced results.
Ramanujan prime, Ramanujan theta function, partition Formulae and Mock Theta Functions have shown the way for entire new areas of work and inspired for further research. His contributions to mathematical analysis, number theory, infinite series, and continued fractions, including their solutions considered to be unsolvable.
The Number 1729 is the smallest number expressible as the sum of two cubes in two different ways. It is an Interesting number that no number will have that type of characteristics.
The two different ways are,
1729 = 13 + 123
1729 = 93 + 103.
This was proven by Ramanujan Hence, 1729 became as Ramanujan’s Number.
G.H. Hardy gave a quotation for Ramanujan that “Every positive integer was one of Ramanujan’s personal friends”.
