I tell personal stories associated with aspects of the theory, and I hope they are interesting and compelling. I don't feel you're going to change a grownup's mind in one reading. People have to be exposed to scientific ideas over and over again for years. It's also not a textbook.

I feel that I've often pointed out that there are countless aspects of life and nature that scientists and scientific thinkers cannot explain. Why the universe is accelerating in its expansion and what came before the Big Bang serve as compelling examples. The process of science provides a way to seek answers to those questions.

There's nothing I believe in more strongly than getting young people interested in science and engineering, for a better tomorrow, for all humankind.
