I'm not hard to find. I'm all over the Internet.

I believe that the manned space program can engage the public by advancing the space frontier. Every next mission takes you farther out in space than you were before, either technologically or in terms of distance.

When you advance a frontier and you do tomorrow what's never been done today, you have to innovate to make that happen. You become an innovation culture. When I grew up, every time I turned around it was, "Oh, here's the longest bridge or the deepest tunnel or the fastest airplane." And I originally thought that was just kind of like a pissing contest with men with too much testosterone. And then I realized that to make the tallest building you have to innovate. To make the fastest train you have to design the train in a way that it's never been designed before.

There are two ways you can receive energy from your environment: One is molecules bumping against you. That's the air. The other is radiative energy. That's what you're feeling from the sun. When they say "Get out of the sun, out of the heat," the air is the same temperature; it's just you're exposed to sunlight.

Nothing is a thing: it's nothing. So I can imagine a place where there's not even nothing.

For centuries, magicians have intuitively taken advantage of the inner workings of our brains.

Climate change has taken on political dimensions. That's odd because I don't see people choosing sides over E=Mc2 or other fundamental facts of science.
