I'm doing a book, 'Chasing Science,' about the pleasures of science as a spectator sport.

That's really what SF is all about, you know: the big reality that pervades the real world we live in: the reality of change. Science fiction is the very literature of change. In fact, it is the only such literature we have.

The science fiction method is dissection and reconstruction.

I'm pretty catholic about what constitutes science fiction.

Advertising reaches out to touch the fantasy part of people's lives. And you know, most people's fantasies are pretty sad.

The big new development in my life is, when I turned 80, I decided I no longer have to do four pages a day. For me, it's like retiring.

On this day I want to tell you about, which will be about a thousand years from now, there were a boy, a girl and a love story.
