1887-1920

mathematician

*The number 1729 is known as the Hardy–Ramanujan number after a famous visit by Hardy to see Ramanujan at a hospital. In Hardy’s words:*

* I remember once going to see him when he was ill at Putney. I had ridden in taxi cab number 1729 and remarked that the number seemed to me rather a dull one, and that I hoped it was not an unfavorable omen. “No”, he replied, “it is a very interesting number; it is the smallest number expressible as the sum of two cubes in two different ways.”*

*Immediately before this anecdote, Hardy quoted Littlewood as saying, “Every positive integer was one of Ramanujan’s personal friends.”*
