There is an underlying timelessness in the basic conversation that is mathematics.

Mathematical objects are determined by - and understood by - the network of relationships they enjoy with all the other objects of their species.

The proof of Fermat's Last Theorem underscores how stable mathematics is through the centuries - how mathematics is one of humanity's long continuous conversations with itself.

In the history of the concept of number has been adjective (three cows, three monads) and noun (three, pure and simple), and now ... number seems to be more like a verb (to triple).

Sometimes a line of mathematical research extending through decades can be thought of as one long conversation in which many mathematicians take part. This is fortunately true at present.

Once you make a decision, the universe conspires to make it happen.

Be together, in the moment of, enjoy each other, love each other, support each other, until the next time...Life is too short.

But some things are more important than being happy. Like being free to think for yourself.

We stand now at the turning point between two eras. Behind us is a past to which we can never return...

I've had great success in everything I've done.

Whitewashing the pump won't make the water pure.

As beautiful as the chance encounter of a sewing machine and an umbrella on an operating table.

I always want objects in my home that have a connection to me or something I've loved. It's still stuff, but it's stuff that has meaning.

What has made me most proud - the things that I've done that I feel the most pride about - is helping people care about making the world better.

Meaning is man-created. And because you constantly look for meaning, you start to feel meaninglessness.
