Śrīnivāsa Rāmānujan

Srinivasa Ramanujan (1887-1920) was one of the great geniuses of our times. He made significant contributions to the analytical theory of numbers, elliptic functions, continued fractions and infinite series, etc. Besides his published works. Ramanujan left behind several notebooks filled with great number of highly intriguing results that mathematicians have continued to work on in the 21st century also. Even during his last days when he was seriously ill, Ramanujan was doing profound discoveries in mathematics. There is an interesting anecdote associated with the number 1729. It is known as Ramanujan number. It is the smallest number which can be expressed as the sum of two cubes in two different ways.

1729 = 13+ 123= 93+ 103
