For me it's been very exciting to contribute to the public's understanding of how rich and wondrous science is.

Intelligence is the ability to take in information from the world and to find patterns in that information that allow you to organize your perceptions and understand the external world.

Einstein comes along and says, space and time can warp and curve, that's what gravity is. Now string theory comes along and says, yes, gravity, quantum mechanics, electromagnetism - all together in one package, but only if the universe has more dimensions than the ones that we see.

When you drive your car, E = mc2 is at work. As the engine burns gasoline to produce energy in the form of motion, it does so by converting some of the gasoline's mass into energy, in accord with Einstein's formula.

My best teachers were not the ones who knew all the answers, but those who were deeply excited by questions they couldn't answer.

I can't stand clutter. I can't stand piles of stuff. And whenever I see it, I basically just throw the stuff away.

I believe we owe our young an education that captures the exhilarating drama of science.
