How hardy discovered ramanujan?

Answer 1

C.H.Hardy was a British mathematician. Srinivasa Ramanujan was an Indian mathematician. Hardy visited Ramanujan in 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." Hence the Hardy-Ramanjuran number which is 1729.
