I love the future we might invent for ourselves that I have not yet dreamt of.

I don't have specific television ambitions in the sense that I remain fundamentally and academic, and so, my innermost ambitions are what's the next discovery I can make; that's in my direct center.

The first colony on Mars is not going to be built by a private company. How are you going to make money? You're not.

Today secular philosophers call that kind of divine invocation God of the gaps-which comes in handy, because there has never been a shortage of gaps in people's knowledge.

After your first job, is anyone asking you what your GPA was? No, they don't care. They ask you: Are you a good leader? Do people follow you? Do you have integrity? Are you innovative? Do you solve problems? Somebody's got to do that homework and redesign the educational system so that it can actually train people to be successful in life.

There's nothing a teacher likes better than ten minute videos. It's not the whole class, but it's not too short, it's enough to wrap a lesson plan around.

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.
