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.

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

The science fiction method is dissection and reconstruction.

In terms of stories I would buy for a science fiction magazine, if they take place in the future, that might do it.

You can't really predict the future. All you can do is invent it.

If you don't care about science enough to be interested in it on its own, you shouldn't try to write hard science fiction. You can write like Ray Bradbury and Harlan Ellison as much as you want.

I was thinking of writing a little foreword saying that history is, after all, based on people's recollections, which change with time.
