Turbulence is the most important unsolved problem of classical physics.

If you don't like it, go somewhere else, to another universe where the rules are simpler.

A very great deal more truth can become known than can be proven.

If it disagrees with experiment, it's wrong.

It is in the admission of ignorance and the admission of uncertainty that there is a hope for the continuous motion of human beings in some direction that doesn't get confined, permanently blocked, as it has so many times before in various periods in the history of man.

I'm going to play with physics, whenever I want to, without worrying about any importance whatsoever.

I'd hate to die twice. It's so boring.
