The greatest problem for mathematicians now is probably the Riemann Hypothesis.

However impenetrable it seems, if you don't try it, then you can never do it.

I grew up in Cambridge in England, and my love of mathematics dates from those early childhood days.

There are proofs that date back to the Greeks that are still valid today.

Mathematics... is a bit like discovering oil. ... But mathematics has one great advantage over oil, in that no one has yet ... found a way that you can keep using the same oil forever.

It's fine to work on any problem, so long as it generates interesting mathematics along the way - even if you don't solve it at the end of the day.

I had this rare privilege of being able to pursue in my adult life, what had been my childhood dream.
