I developed my camera system, called the Medusa, jointly with a colleague down in Australia as a method of exploring the ocean unobtrusively. The critical thing was that we didn't use white light, which I believe has been scaring the animals away.

It's a little-appreciated fact that most of the animals in our ocean make light. I've spent most of my career studying this phenomenon called bioluminescence. I study it because I think understanding it is critical to understanding life in the ocean where most bioluminescence occurs.

Exploration is the engine that drives innovation. Innovation drives economic growth.

Exploration is the engine that drives innovation. Innovation drives economic growth. So let's all go exploring.

Walking is my main method of relaxation. I don't go over my lines or try to solve the world's problems, I just enjoy the scenery and the wildlife.

Ours is a world which feels so unsettled and dangerous in large ways, whether it's terrorism or global financial meltdown or climate change - huge things that affect us deeply, and yet things about which we can do, individually, very little.

I worked as a draftsman for the Department of Environmental Protection, and as a teacher, in N.Y.C.; at a big bank and a small ad agency, a tiny law firm and a few giant ones; as a cashier and a dishwasher; preparing deli sandwiches and stringing tennis racquets and pruning evergreens into conical Christmas-tree shapes.

Developed countries should support developing countries in tackling climate change. This not only is their responsibility, but also serves their long-term interests.
