Once Ramanujan, who was in London, was sick.
Hardy came to visit him in a Taxi.
This was the conversation
That’s a very dull number
From then on,
number 1729 is known as Hardy-Ramanujan Numbers
1729 can be expressed as
1729 = 1 + 1728 = 1 3 + 12 3
Or
1729 = 729 + 1000 = 9 3 + 10 3
Thus,
1729 is the smallest number that can be represented as sum of two cubes in two different ways
