The more I examine the universe and study the details of its architecture, the more evidence I find that the universe in some sense must have known that we were coming.

Boiled down to one sentence, my message is the unboundedness of life and the unboundedness of human destiny.

We won't really understand the brain until we can make models of it which are analog rather than digital, which nobody seems to be trying very much.

It's as great a part of the human adventure to invent things as to understand them. John Randall wasn't a great scientist, but he was a great inventor. There's been lots more like him, and it's a shame they don't get Nobel Prizes.

For me, science is just a bunch of tools - it's like playing the violin.

There is no way to find the best design except to try out as many designs as possible and discard the failures.

There is a great satisfaction in building good tools for other people to use.
