The real question is whether all your pondering and analyses will convince you that life is worth living. That's what it all comes down to.

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.

The number of e-mails and letters that I get from choreographers, from sculptors, from composers who are being inspired by science is huge.
