Science is a process for learning about nature in which competing ideas about how the world works are measured against observations.

We are lucky to live in an age in which we are still making discoveries.

The thing that doesn't fit is the thing that is most interesting.

The shell game that we play ... is technically called 'renormalization'. But no matter how clever the word, it is still what I would call a dippy process! Having to resort to such hocus-pocus has prevented us from proving that the theory of quantum electrodynamics is mathematically self-consistent. It's surprising that the theory still hasn't been proved self-consistent one way or the other by now; I suspect that renormalization is not mathematically legitimate.

Teach principles not formulas.

Turbulence is the most important unsolved problem of classical physics.

The game I play is a very interesting one. It's imagination, in a tight straightjacket.
