I am interested in how cells know what they are and how they should behave in their proper place in the body.

Winning a Nobel Prize isn't about being clever at all. It's about making... at least in physiology or medicine, it's about making discoveries, and you don't have to be clever to make a discovery, I don't think; it just comes up and punches you on the nose.

It's terribly important that you can criticise people's ideas without criticising them, and if they burst into tears, it means that you tend to hold back from getting at the absolute truth.

You don't want to inhibit cell division. You want to inhibit cell division in the cancer cells, and even that is not really where you want to do it. You actually want to destroy the cancer cells, which is a different matter altogether. Just stopping them isn't enough - you really want to kill them.

I am trying to write stuff that is different. I am a big science fan. I read a lot of science, and 'Wonderland' has a lot of science in it. I don't know. They are hard to describe... We are living in a wonderland age of science.

What I love about comedy is that it's unquestionably working. There are varying degrees of that, where there's something that makes you smile and is funny versus something that makes you hysterically laugh.

You must keep people happy backstage because that affects what's onstage. During a run, the playwright feels like the mayor of a small town filled with noble creatures who have to get out there and make it brand new every night. When a production works, it's unlike any other joy in the world.

I have arrived at the conviction that the neglect by economists to discuss seriously what is really the crucial problem of our time is due to a certain timidity about soiling their hands by going from purely scientific questions into value questions.
