A computation is a process that obeys finitely describable rules.

Now, being a science fiction writer, when I see a natural principle, I wonder if it could fail.

All living things are gnarly, in that they inevitably do things that are much more complex than one might have expected.

We're part of the unfolding world, surfing the chaotic waves

One of the nice things about science fiction is that it lets us carry out thought experiments.

I like a book better if I can't predict what's going to happen.

If we suppose that many natural phenomena are in effect computations, the study of computer science can tell us about the kinds of natural phenomena that can occur.
