Physicists are more like avant-garde composers, willing to bend traditional rules... Mathematicians are more like classical composers.

The absolute worst thing that you ever can do, in my opinion, in bringing science to the general public, is be condescending or judgmental. It is so opposite to the way science needs to be brought forth.

When I give this talk to a physics audience, I remove the quotes from my 'Theorem'.

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

Our eyes only see the big dimensions, but beyond those there are others that escape detection because they are so small.

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.

I like 'The Simpsons' quite a lot. I love the irreverent character of the whole show. It's great.
