'Jurassic Park' has a lot of science in it - and a lot of it is wrong - but if it was all accurate, it would be a documentary.

Almost all of my graduate students say that they got interested in dinosaurs because of 'Jurassic Park.'

Scientists are actually preoccupied with accomplishment. So they are focused on whether they can do something. They never stop to ask if they should do something.

Let's be clear. The planet is not in jeopardy. We are in jeopardy. We haven't got the power to destroy the planet - or to save it. But we might have the power to save ourselves.

What is this place? Jurassic Park?

Comparing science and religion isn't like comparing apples and oranges - it's more like apples and sewing machines.
