There are just two people entitled to refer to themselves as "we"; one is the editor and the other is the fellow with a tapeworm.

Talk about science with everyone you meet. Especially talk about climate change. It needs to become a part of our everyday conversation (the way it is everywhere else in the world).

Everybody remembers numbers and computers remember numbers. People remember procedures and computers certainly remember procedures. But the other thing that's still important is that your perception as a human is affected subtly by all this stuff that you can't quite articulate. You run your life according to all this stuff that's happened to you. All of your memories affect everything you do whereas with a computer, there's adaptive software and things, but it's more literal.

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.

But investment in space stimulates society, it stimulates it economically, it stimulates it intellectually, and it gives us all passion.
