The good thing about science is that it's true whether or not you believe in it.

Cutting PBS support (0.012% of budget) to help balance the Federal budget is like deleting text files to make room on your 500Gig hard drive

How many times have you heard a person in a workplace say, "I wasn't trained for this!" That's an impossible reaction from a physicist, who would say, instead, "Cool. A problem I've never seen before. Let's see how I can figure out how to solve it!"

We spend the first year of a child's life teaching it to walk and talk and the rest of its life to shut up and sit down. There's something wrong there.

To view space as, "Well, let's go to Mars now," or "Let's do this now," maybe we should rethink of space as our backyard and have a suite of launch vehicles that can enable any ambition a person has regarding space. It's the same way you can go to buy a car: I want to go offroading, I'll buy this model. I'm a city driver, that's this model. I want to use less fuel, well, that's this model. They're not selling you one car, you have options. So when I think of space, I think of having options.
