What is the shape of space? Is it flat, or is it bent? Is it nicely laid out, or is it warped and shrunken? Is it finite, or is it infinite? Which of the following does space resemble more: (a) a sheet of paper, (b) an endless desert, (c) a soap bubble, (d) a doughnut, (e) an Escher drawing, (f) an ice cream cone, (g) the branches of a tree, or (h) a human body?

I think dry nanotechnology is probably a dead-end.

It's a waste to chase the pipe dream of a magical tiny theory that allows us to make quick and detailed calculations about the future. We can't predict and we can't control. To accept this can be a source of liberation and inner peace. We're part of the unfolding world, surfing the chaotic waves.

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.

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

The world is magic. Science is but an insipid style of sorcery.
