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

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

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.

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

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

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.

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