The idea of an ordered and elegant universe is a lovely one. One worth clinging to. But you don't need religion to appreciate the ordered existence. It's not just an idea, it's reality. We're discovering the hidden orders of the universe every day.

These are people from everywhere, from Lawrence Livermore and JPL and Sandia National Labs, the FBI, all over the place, real scientists who see what we're doing, and they consistently thank us. "I agree your results aren't always right," they'll say, "but your methods are clearly showing that science is a re-creative process, and it's an interesting process because it's messy, and no other shows show that."

Let's get on our knees and pray. I don't know to whom. Is there a patron saint of ballistics gel?

I have concluded through careful empirical analysis and much thought that somebody is looking out for me, keeping track of what I think about things, forgiving me when I do less than I ought. Giving me strength to shoot for more than I think I’m capable of. I believe they know everything that I do and think, and they still love me, and I’ve concluded, after careful consideration, that this person keeping score is me.

Audiences of critical thinkers are my favorite kinds of audiences. There are jokes I tell in the show that don't get laughs unless I am in front of an audience of critical thinkers. Put me in front of a crowd of science teachers or astronauts! The guileless aren't our audience - it's the critical thinkers we love.

I'm not a sculptor; I'm a hard-edged model maker. You give me a drawing, you give me a prop to replicate, you give me a crane, scaffolding, parts from 'Star Wars' - especially parts from 'Star Wars' - I can do this stuff all day long. It's exactly how I made my living for 15 years.

Am I about to feel really, really stupid?
