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

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 anything I can imagine.

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

I tried to fit it in with some previous broad conceptual understanding of some part of mathematics that would clarify the particular problem I was thinking about.

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

Fermat said he had a proof.

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 no solutions up to infinity.

Always try the problem that matters most to you.

Well, some mathematics problems look simple, and you try them for a year or so, and then you try them for a hundred years, and it turns out that they're extremely hard to solve.

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

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

Perhaps the methods I needed to complete the proof would not be invented for a hundred years. So even if I was on the right track, I could be living in the wrong century.

I'm sure that some of them will be very hard and I'll have a sense of achievement again, but nothing will mean the same to me - there's no other problem in mathematics that could hold me the way that this one did.

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

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

I realized that anything to do with Fermat's Last Theorem generates too much interest.

The only way I could relax was when I was with my children.

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

I don't believe Fermat had a proof. I think he fooled himself into thinking he had a proof.

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

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

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 math problems, and we just have to find new ones to capture our attention.

There's also a sense of freedom. I was so obsessed by this problem that I was thinking about if all the time - when I woke up in the morning, when I went to sleep at night, and that went on for eight years.

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

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 methods.

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 went on for eight years.

I loved doing problems in school.

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 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.

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

It could be that the methods needed to take the next step may simply be beyond present day mathematics. Perhaps the methods I needed to complete the proof would not be invented for a hundred years.

I loved doing problems in school. I'd take them home and make up new ones of my own. But the best problem I ever found, I found in my local public library. I was just browsing through the section of math books and I found this one book, which was all about one particular problem - Fermat's Last Theorem.

Pure mathematician just love to try unsolved problems they love a challenge.

Socialism proposes no adequate substitute for the motive of enlightened selfishness that today is at the basis of all human labor and effort, enterprise and new activity.

I am tomorrow, or some future day, what I establish today. I am today what I established yesterday or some previous day.

If I had to come up with something that just came to me, I think growing up in a small town, I want knowledge. I still think today, knowledge is one of the keys.

There's more than a few remnants left in German welfare policy today. Many Germans eagerly condemn Hitler's fascism but won't examine the other reasons why the Third Reich succeeded for a season.

Compared to today's salaries, our cut was minuscule but it was very good for the time.

The NFL today has bigger, stronger, bodies than ever, moving faster than ever, hitting a stationary object harder than ever before - so the physics of the hit have changed.

The President of today is just the postage stamp of tomorrow.

I'm so happy because today I found my friends - they're in my head.

I don't know where the stock market is going, but I will say this, that if it continues higher, this will do more to stimulate the economy than anything we've been talking about today or anything anybody else was talking about.

I'm not up on today's television for children, because it's mostly cartoons that don't seem to interest me.

We aim in the domain of politics at republicanism; in the domain of economics at socialism; in the domain of what is today called religion, at atheism.

Today's interpretations of religion are often backward and contradict the needs of civilization.

The most profound, tangible influence in my life has been my wife, Monique. I don't know that I would even be alive were it not for her, and I certainly would not be the person that I am today.

Were you to read the British press today, you would learn that the British Empire never forgets its defeats.

As patients and consumers, we are better informed today about our health care than any previous generation.

A couple of guys won Academy Awards for the things that I turned down. Today, after coming to terms with everything, after being in therapy for a long time-there are areas where I will compromise.
