He was an Indian mathematician whose contribution to the field of mathematics is immense. He was a self-taught genius who worked on continued fractions, infinite series, and electrical functions. He also worked notably on hypergeometric series. His extraordinary familiarity with numbers can be shown by some incidents. One of those incidents was in a hospital in England. When his Cambridge professor G.H. Hardy visited him and remarked that he had taken taxi number 1729, Ramanujan immediately responded that this number was quite remarkable. He said that it is the smallest integer that can be represented in two ways by the sum of two cubes: 1729= 1³+12³=9³+10³.
