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

Always remember, believe in today, believe in tomorrow, believe in yourself, and whatever happens, don’t jump.

We need scientifically literate voters and taxpayers for the future. We need engineers that can build stuff and solve problems.

The Earth is not 6,000 or 10,000 years old. It’s not. And if that conflicts with your beliefs, I strongly feel you should question your beliefs.

Also, we have a strange situation where we have malnourished fat people. It’s not that we need more food. It’s that we need to manage our food system better.

Evolution is the fundamental idea in all of life science, in all of biology. The key to our being here now is time, 4.54 billion (Earth) years of time.

I meet so many people who are intimidated by arithmetic.

I hope climate science becomes the big thing. And then what I want is electrical engineers to solve the world’s energy problems, energy distribution problems.

If you decide to become a dancer on Broadway, never say who your favorite dance partner is, because members of the media will presume you never want to dance with anybody else.

In another couple centuries I’m sure that worldview won’t even exist. There’s no evidence for it.

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.

The more you find out about the world, the more opportunities there are to laugh at it.

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.

Teaching creationism in science class as an alternative to evolution is inappropriate.

I say to the grown-ups, ‘If you want to deny evolution and live in your world that’s completely inconsistent with everything we’ve observed in the universe that’s fine. But don’t make your kids do it.’

Hard to find anything lovelier than a tree. They grow at right angles to a tangent of the nominal sphere of the Earth.
