Science Quotes by Srinivasa Ramanujan (2 quotes)
Replying to G. H. Hardy's suggestion that the number of a taxi (1729) was dull: No, it is a very interesting number; it is the smallest number expressible as a sum of two cubes in two different ways, the two ways being 13 + 123 and 93 + 103.
— Srinivasa Ramanujan
An equation means nothing to me unless it expresses a thought of God.
— Srinivasa Ramanujan
Quotes by others about Srinivasa Ramanujan (8)
I remember once going to see him 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.
No mathematician should ever allow him to forget that mathematics, more than any other art or science, is a young man's game.
Galois died at twentyone, Abel at twentyseven, Ramanujan at thirtythree, Riemann at forty. There have been men who have done great work later;
[but] I do not know of a single instance of a major mathematical advance initiated by a man past fifty.
A mathematician may still be competent enough at sixty, but it is useless to expect him to have original ideas.
Plenty of mathematicians, Hardy knew, could follow a stepbystep discursus unflaggingly—yet counted for nothing beside Ramanujan. Years later, he would contrive an informal scale of natural mathematical ability on which he assigned himself a 25 and Littlewood a 30. To David Hilbert, the most eminent mathematician of the day, he assigned an 80. To Ramanujan he gave 100.
Srinivasa Ramanujan was the strangest man in all of mathematics, probably in the entire history of science. He has been compared to a bursting supernova, illuminating the darkest, most profound corners of mathematics, before being tragically struck down by tuberculosis at the age of
33... Working in total isolation from the main currents of his field, he was able to rederive 100 years worth of Western mathematics on his own. The tragedy of his life is that much of his work was wasted rediscovering known mathematics.
The seeds from Ramanujan's garden have been blowing on the wind and have been sprouting all over the landscape.

In the simplest array of digits [Ramanujan] detected wonderful properties: congruences, symmetries and relationships which had escaped the notice of even the outstandingly gifted theoreticians.
There is great exhilaration in breaking one of these things.
Ramanujan gives no hints, no proof of his formulas, so everything you do you feel is your own.[About verifying Ramanujan's equations in a newly found manuscript.]
The manuscript looks chaotic, even by mathematics standards.
