i love it when i see srinivasa ramanujan name.

no one ever mentions him or even has a clue to his existence,

let alone his work.

Interesting anecdote regarding Ramanujan:

"The number 1729 is known as the Hardy–Ramanujan number after a famous anecdote of the British mathematician G. H. Hardy regarding a visit to the hospital to see Ramanujan. 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." ”

The two different ways are

1729 = 1 to the 3 + 12 to the 3 = 9 to the 3 + 10 to the 3.

Generalizations of this idea have created the notion of "taxicab numbers". Coincidentally, 1729 is also a Carmichael number."---http://en.wikipedia.org/wiki/Srinivasa_Ramanujan
