Big ideas, big ambitious projects need to be embedded within culture at a level deeper than the political winds. It needs to be deeper than the economic fluctuations that could turn people against an expensive project because they're on an unemployment line and can't feed their families.

When an industry matures, it means it's not advancing, and of course the jobs go overseas. That's the obligation of the multi-national corporation: to put the factory where it can make the widget as cheap as possible. Don't get angry when a corporation does that; we've all bought into this concept. We live in a capitalistic society.

One of the symptoms of an absence of innovation is the fact that you lose your jobs. Everyone else catches up with you. They can do what you do better than you or cheaper than you. And in a multinational corporate-free market enterprise, it is the company's obligation to take the factory to a place where they can make it more cheaply.

Pluto's orbit is so elongated that it crosses the orbit of another planet. Now that's... you've got no business doing that if you want to call yourself a planet. Come on, now! There's something especially transgressive about that.

The methods and tools of science perennially breach barriers, granting me confidence that our epic march of insight into the operations of nature will continue without end.

Although I'm not actually embarrassed by this, I tend not to read books that have awesome movies made from them, regardless of how well or badly the movie represented the actual written story.

Some asteroids have us in their sights. Be nice to sort of go near them and find out what they're made of, possibly tag their ears so they're always broadcasting to us their location. In case one of their trajectories head straight for us, we'll know well in advance to do something about it.

Typically, when you look for role models, you want someone who has your interests and came from the same background. Well, look how restricting that is. What people should do is take role models a la carte. If there's someone whose character you appreciated, you respect that trait.

We think scientific literacy flows out of how many science facts can you recite rather than how was your brain wired for thinking. And it's the brain wiring that I'm more interested in rather than the facts that come out of the curriculum or the lesson plan that's been proposed.

As an educator, I try to get people to be fundamentally curious and to question ideas that they might have or that are shared by others. In that state of mind, they have earned a kind of inoculation against the fuzzy thinking of these weird ideas floating around out there.

Just think for how long humanity was controlled by mystical, magical thinking - the diseases and suffering that led to. We managed to survive, but just barely. It wasn't pretty.

The universe is hilarious! Like, Venus is 900 degrees. I could tell you it melts lead. But that's not as fun as saying, 'You can cook a pizza on the windowsill in nine seconds.' And next time my fans eat pizza, they're thinking of Venus!
