I hope that seeing the excitement of solving this problem will make young mathematicians realize that there are lots and lots of other problems in mathematics which are going to be just as challenging in the future.

Guided only by their feeling for symmetry simplicity and generality and an indefinable sense of the fitness of things creative mathematicians now as in the past are inspired by the art of mathematics rather than by any prospect of ultimate usefulness.

The way in which mathematicians and physicists and historians talk is quite different and what a physicist means by physical intuition and what a mathematician means by beauty or elegance are things worth thinking about.
