I'm revealing information to people. I'm not creating it. And to the extent that people embrace it, I think they're empowered by it, because any time you have a bigger perspective today than you did yesterday, it's got to be only for the good of your mind, your body, your soul.

Scientific truth is not what any one scientist puts forth. It can be that, but it is generally not. It is the sum of multiple studies that all lean in the same direction in their results conducted by different people at different times of different nationalities with different competitive urges who all end up getting the same result. Then you have an emerging scientific truth, and then you put that in the textbooks, and that will never be shown to be wrong later on.

I know of no time in human history where ignorance was better than knowledge.

While I'm a big fan of science fiction, especially as rendered in expensive Hollywood blockbusters, it's the real universe that calls to me. To fall into a black hole, that is more amazing than anything I've ever read in a science-fiction story.

I try to write in a way where you care deeply what the next paragraph will be. I hear the rhythm of prose and that, to me, distinguishes great writing from ordinary writing. By the way, I don't even claim that I'm good. I claim that I value it.

When you innovate, the jobs can't go overseas because other countries haven't figured out how to do it yet.

There is no greater education than one that is self-driven.
