In theory, cars are fairly simple. If they don't start, it's either the fuel system or the electrical system. Teach yourself about the path of each in your engine and tracing it is fairly straightforward. But at the beginning, mastering each new system seems like an unreachable shore. The car is effectively a black box.

Back when I was a professional model-maker at Industrial Light & Magic, my specialty was hard-edged construction - spaceships, miniature sets, and architectural stuff. These objects were sometimes just 12 inches across yet needed enough detail to fill a movie screen.

When I finally got up to Industrial Light And Magic to work on the 'Star Wars' movies as a model-maker, it felt like dying and going to heaven.

I find it's too much for me to read endless critiques, even if we're being well-defended, of exactly what we're doing. When someone tells us something we're doing wrong on the boards, we try to respond, we try to be responsive to the fan boards, but yeah, I can't read them.

That was excellent! I mean, it didn't do anything, but it looked really cool!

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.

Gravity. It's not just a good idea; it's the law!
