I've taken a philosophical position on e-mail. Although I think it's a wonderful communication technology, and it has a lot of good uses, it is abused quite a lot.

As both a scientist and a humanist myself, I have struggled to understand different claims to knowledge, and I have eventually come to a formulation of the kind of religious belief that would, in my view, be compatible with science.

Children grow rapidly, forget the centuries-long embrace from their parents, which to them lasted but seconds. Children become adults, live far from their parents, live their own houses, learn ways of their own, suffer pain, grow old. Children curse their parents for their wrinkled skin and hoarse voices. Those now old children also want to stop time, but at another time. They want to freeze their own children at the center of time.

Suppose time is a circle, bending back on itself. The world repeats itself, precisely, endlessly.

One day I'm going to write a book about osprey. It has really gotten deep into my bloodstream. So when you ask what else I do, I feel like this is part of what I do....is to watch these birds.

I re-read a lot of books that I like a lot. There are some books that I try to reread every couple of years. A good book changes for you every few years because you are in a different place in your own life.

I spend a lot of time just listening to the ospreys. I watch them go through their life cycle. They spend the winter in South America. The mother and father osprey stay together. It's a monogamous relationship. And every summer they raise a new brood of children. They came back to the nest in the middle of April. They take separate vacations in the winter - the mother and father.
