I think a very big curiosity. I’m very curious and I like to understand things and not only science but also other things where I just try to find out why things work or how things work. Science and nature caught my attention as a small child already. I was growing up in a city but we had a garden and I loved the garden and then often on vacation I was at a farm and I loved these animals and plants and so on, so I was attracted very early on and then we had a very good teaching actually at my … I don’t know whether my teachers really had much of a role because I was determined very early, but then I also did music and I did languages and Literature and so on. I have broad interests actually other than science, but this is really true, this curiosity.

I always think about things, and if something puzzles me… Well, that of course was one of Darwin’s secrets. Whenever something puzzled him, he tried find a theory. He made a conjecture, as (Karl) Popper would call it, and see if it worked out and that’s true even today.

I have also benefited from teaching; as I try to explain my views to students with critical and open minds, I find myself continually being challenged to go back and rethink ideas. I now see teaching and research as complementary, mutually reinforcing activities.

The questions of the students are often the source of new research.  They often ask profound questions that I’ve thought about at times and then given up on, so to speak, for a while.  It wouldn’t do me any harm to think about them again and see if I can go any further now.  The students may not be able to see the thing I want to answer, or the subtleties I want to think about, but they remind me of a problem by asking questions in the neighborhood of that problem.  It’s not so easy to remind yourself of these things.

I was jealous as hell.

The End Of The Affair by Graham Greene.

One day you write nothing, the next you write eight pages. It’s not in your hands.

There is an awful lot of pious theatre at the moment, where you go to have what you already believed reinforced.

I get to airports ridiculously early. It’s an uncontrollable urge.

I’m much much closer to my children than my father was to me, and I would hope that the quality of love I’ve given them is different from the quality my father gave me.
