What I can't completely understand is most other people's fascination with what the famous among us do with their lips and the rest of their bodies.

You know what my earliest memories are? Going from one burlesque town to another. My father was in burlesque.

If scientists can't communicate with the public, with policy makers, with one another, the future is going to be held back. We're not going to have the future that we could have.

For me, I find that even though I've accomplished a few things in my life, looking back on accomplishments doesn't give me a sense of satisfaction.

I have a funny mental framework when I do physics. I create an imaginary audience in my head to explain things to - it is part of the way I think. For me, teaching and explaining, even to my imaginary audience, is part of the process.

A drawing is an autobiographical record of one's discovery of an event - either seen, remembered or imagined. A 'finished' work is an attempt to construct an event in itself.

The disturbing truth about science communication is that we have theories and ways of delivering messages that really are like putting a candle to the dark, as Carl Sagan would say. We aren't sure what will work, when, or how much. But for all that uncertainty, that doesn't mean we shouldn't try.

I enjoyed mathematics from a very young age. At the beginning of college, I had this illusion, which was kind of silly in retrospect, that if I just understood math and physics and philosophy, I could figure out everything else from first principles.
