Chapter 7: Cubes and Cube Roots
There is a story about one of India’s great mathematical geniuses, S. Ramanujan. Once another famous mathematician Prof. G.H. Hardy came to visit him in a taxi whose number was 1729. While talking to Ramanujan, Hardy described this number as “a dull number”. Ramanujan quickly pointed out that 1729 was indeed interesting. The interesting part about the number Ramanujan was talking about was it can be represented as a sum of a cube of numbers in many ways.
