Just because we can't find a solution it doesn't mean that there isn't one..

But the best problem I ever found, I found in my local public library..

Pure mathematicians just love to try unsolved problems - they love a challenge..

We've lost something that's been with us for so long, and something that drew a lot of us into mathematics. But perhaps that's always the way with ma….

I really believed that I was on the right track, but that did not mean that I would necessarily reach my goal.

Always try the problem that matters most to you..

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

I carried this problem around in my head basically the whole time. I would wake up with it first thing in the morning, I would be thinking about it a….

The definition of a good mathematical problem is the mathematics it generates rather than the problem itself..

Mathematicians aren't satisfied because they know there are no solutions up to four million or four billion, they really want to know that there are ….

Perhaps I could best describe my experience of doing mathematics in terms of entering a dark mansion. You go into the first room and it's dark, compl….

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

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

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

Fermat said he had a proof..

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..

Then when I reached college, I realized that many people had thought about the problem during the 18th and 19th centuries and so I studied those meth….

I was so obsessed by this problem that I was thinking about it all the time - when I woke up in the morning, when I went to sleep at night - and that….

That particular odyssey is now over. My mind is now at rest..

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 c….

I know it's a rare privilege, but if one can really tackle something in adult life that means that much to you, then it's more rewarding than anythin….
