Nothing is boring if you look at carefully.

Plasma seems to have the kinds of properties one would like for life. It's somewhat like liquid water--unpredictable and thus able to behave in an enormously complex fashion. It could probably carry as much information as DNA does. It has at least the potential for organizing itself in interesting ways.

That's the beautiful thing about science - that it's all about things we don't understand, not just the things we do understand.

Some things go better than you expected, other things go worse, so I'm... I think the only sensible thing is just to wait and see and what I'm doing when I'm writing books - I'm not doing science so much anymore.

The fact that the climate is getting warmer doesn't scare me at all. There's no reason why one should be scared.

It has become part of the accepted wisdom to say that the twentieth century was the century of physics and the twenty-first century will be the century of biology.

I think it's much better to have your eyes open, but on the other hand, of course it can do harm if you tell people look, there's all these terrible things you can do and then some idiot may go ahead and do it.
