One favorite story about Ramanujan
One favorite story about Ramanujan revolves around a visit that Hardy paid to him in hospital. Hardy and Ramanujan had a habit of discussing the properties of different numbers. On this particular visit, Hardy commented to Ramanujan that the number of the taxi that he had just arrived in was 1729 -- a very uninteresting number. Ramanujan quickly replied that it was in fact a very interesting number as it was the smallest number that could be represented as the sum of two cubes in two ways:
1729 = 103 + 93
and
1729 = 123 + 13
Dear Sir,
ReplyDeleteSuch numbers are sometimes also called Taxicab Numbers.
By the way, equations such as c=a3+b3 are called Diophantine Equations, named after Diophantus (sometime in the period 200 BC - 400 AD, probably about 250 AD), when they involve only integers.
It was a good blog keep it up.
