I always liked show biz and got to make a few training films at Boeing.

Our goal in science is to discover universal laws of nature. That pursuit fills me with wonder.

The oncoming trouble I speak of is climate change. It's going to affect all of you in the same way the Second World War consumed people of my parent's generation.

When we sit down to draw or paint the sun's rays, we generally use yellow because in the morning and the evening with the blue light scattered away so strongly you're left with a little bit of red and it comes out yellowish.

There are two questions that get to us all: Are we alone in the Universe? And, where did we come from? For me, science provides a much more satisfactory way to seek answers than does any religion I've come across. With that said, the universe is mysterious and wonderful. It fills me with reverence for nature and our place among the stars; our place in space.

Along with the evidence of common sense, researchers have proven scientifically that humans are all one people. We're a lot like dogs in that regard. If a Great Dane interacts (can we say interact?) with a Chihuahua, you get a dog.

From an evolutionary standpoint you can't just wipe everything out and start over, and I don't think you can do it in the school system either.
