Mathematics is not a contemplative but a creative subject.

317 is a prime, not because we think so, or because our minds are shaped in one way rather than another, but because it is so, because mathematical reality is built that way.

I do not know an instance of a major mathematical advance initiated by a man past fifty

There is always more in one of Ramanujan's formulae than meets the eye, as anyone who sets to work to verify those which look the easiest will soon discover. In some the interest lies very deep, in others comparatively near the surface; but there is not one which is not curious and entertaining.

A month's intelligent instruction in the theory of numbes ought to be twice as instructive, twice as useful, and at least 10 times as entertaining as the same amount of 'calculus for engineers'.

Cricket is the only game where you are playing against eleven of the other side and ten of your own.

I am interested in mathematics only as a creative art.
