This is what GH Hardy, the famous mathematician
observed, and it is the most famous anecdote related to
Ramanujan and we all remember him for 1729.


I remember once going to see [Ramanujan] when
he was lying 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.'


Distinct property of 1729

1729 = 1^3 +12^3 = 9^3 + 10 ^3
