Something that bothered people about 'Dawson's Creek' but as a writer, I kind of dug: writing those kids as though they were college grad students. It was fun and liberating and made for a true sort of writer's show. It was a fun year for me, because I got to get out of debt with my first TV job, and I learned a ton.

On 'Dawson's Creek,' those kids were supposed to be outsider kids - you know, wrong-side-of-the-track kids, weirdo kids. And I just felt like there's no universe out there where Katie Holmes isn't the prom queen, hottest girl in school.

'Freaks and Geeks' was my favorite show when it was on, by a wide measure. And that's the show I wanted to do. I noodled with the idea of doing a show about teenagers that told small stories, small moments of personal growth.

Supplying fuel for a Mars expedition from the lunar surface is often suggested, but it's hard to make it pay off - Moon bases are expensive, and just buying more rockets to launch fuel from Earth is relatively cheap.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
