I did play the guitar and sing; I was in a band called The Estrogens: three females and one very brave guy.

I read about eastern philosophy and religion and existentialism. All that introspective thinking got me thinking about the great beyond. That turned my sights from inwards to outwards, and I started becoming interested in the makeup of the universe, and I started reading about astronomy, planets, and galaxies.

The Saturn system is a rich planetary system. It offers mystery, scientific insight, and obviously splendour beyond compare, and the investigation of this system has enormous cosmic reach... just studying the rings alone, we stand to learn a lot about the discs of stars and gas that we call the spiral galaxies.

Every type of ring behavior we have seen around Jupiter, Uranus, or Neptune can be found in orbit around Saturn. And Saturn's ring system offers the greatest promise of understanding processes in operation within all disk systems, not just those found around planets.

I've never been convinced that experience is linear, circular, or even random. It just is. I try to put it in some kind of order to extract meaning from it, to bring meaning to it.

I'm used to the fact that the world views movie actors as personalities. I'm in the extremely fortunate position of making a living at something I'm passionate about. It's all about choices. By the nature of what I do, I make a choice. I invite them in.

There are many differences between medicine and teaching, but they have much in common. Both involve craft and personal expertise, learned through experience; but both can be informed by the experience of others.

Very often I've known people who wouldn't say a word to each other, but they'd go to see movies together and experience life that way.
