Computers have proved to be formidable chess players. In fact, they've beaten our top human chess champions.

It's part of our pop culture to give animals human personalities and talents.

Mars once was wet and fertile. It's now bone dry. Something bad happened on Mars. I want to know what happened on Mars so that we may prevent it from happening here on Earth.
-
There is always a place I can take someone's curiosity and land where they end up enlightened when we're done. That's my challenge as an educator. No one is dumb who is curious. The people who don't ask questions remain clueless throughout their lives.

'Cosmos' wouldn't deserve its place in primetime evening network television were it not a landscape on which compelling stories were told. People, when they watch TV in the evening, want to see stories, and science simply tells the best stories.
-
Space exploration is a force of nature unto itself that no other force in society can rival.
-
No one is dumb who is curious. The people who don't ask questions remain clueless throughout their lives.
-
Adults, who outnumber kids four or five to one, are in charge. We wield the resources, run the world, and completely thwart kids' creativity.
-
I want to know what dark matter and dark energy are comprised of. They remain a mystery, a complete mystery. No one is any closer to solving the problem than when these two things were discovered.
-
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!

As an American, I grew up in an era where we led the world in everything. Everything!

Let's say intelligence is your ability to compose poetry, symphonies, do art, math and science. Chimps can't do any of that, yet we share 99 percent DNA. Everything that we are, that distinguishes us from chimps, emerges from that one-percent difference.

My parents didn't know much science; in fact, they didn't know science at all. But they could recognize a science book when they saw it, and they spent a lot of time at bookstores, combing the remainder tables for science books to buy for me. I had one of the biggest libraries of any kid in school, built on books that cost 50 cents or a dollar.
-
We define ourselves as intelligent. That's odd, because we're doing the definition - We're creating our own definition and saying, 'We are intelligent!'
-
What people are really after is, what is my stance on religion or spirituality or God? And I would say, if I find a word that came closest, it would be agnostic.
-
Half of my library are old books because I like seeing how people thought about their world at their time. So that I don't get bigheaded about something we just discovered and I can be humble about where we might go next. Because you can see who got stuff right and most of the people who got stuff wrong.

I've spent quality time in the aerospace community, with my service on two presidential commissions, but at heart, I'm an academic. Being an academic means I don't wield power over person, place or thing. I don't command armies; I don't lead labor unions. All I have is the power of thought.
-
The problem is not scientifically illiterate kids; it is scientifically illiterate adults. Kids are born curious about the natural world. They are always turning over rocks, jumping with two feet into mud puddles and playing with the tablecloth and fine china.
-
Some of the most productive times in the histories of nations have been when they were badly stressed - economically, politically, culturally or socially. It's possible to be stressed to a point that more creativity is stimulated than would otherwise be the case. I think it is true that necessity is the mother of invention.
-
You don't take a dead cat to the vet. I mean you might, but why?
-
I see all this talk about jobs going overseas as a symptom of the absence of innovation. And the absence of innovation is a symptom of there being no major national priority to advance a frontier.
-
For me, the most fascinating interface is Twitter. I have odd cosmic thoughts every day and I realized I could hold them to myself or share them with people who might be interested.
-
Stephen Hawking's been watching too many Hollywood movies. I think the only kind aliens in Hollywood are the ones created by Steven Spielberg - 'Close Encounters of the Third Kind' and 'E.T.,' for example. All other aliens are trying to suck our brains out.

Most religious people in America fully embrace science. So the argument that religion has some issue with science applies to a small fraction of those who declare that they are religious. They just happen to be a very vocal fraction, so you got the impression that there are more of them than there actually is.
