The boldness of asking deep questions may require unforeseen flexibility if we are to accept the answers.

Time allows change to take place and the very evolution of the universe is what requires some conception of time. Mathematically can we write down a universe that doesn't have time? Sure. Do we think that would be realised in the larger reality that is out there? None of us take that possibility seriously.

If the theory turns out to be right, that will be tremendously thick and tasty icing on the cake.

I think math is a hugely creative field, because there are some very well-defined operations that you have to work within. You are, in a sense, straightjacketed by the rules of the mathematics. But within that constrained environment, it's up to you what you do with the symbols.

I believe we owe our young an education that captures the exhilarating drama of science.

The real question is whether all your pondering and analyses will convince you that life is worth living. That's what it all comes down to.

Physicists have come to realize that mathematics, when used with sufficient care, is a proven pathway to truth.
