“I used to play ultimate Frisbee, and I just got a reputation for making popcorn at parties. I don’t mean to brag on myself, but I make the popcorn in the pot, and it comes out fine every time.”

When we see the shadow on our images, are we seeing the time 11 minutes ago on Mars? Or are we seeing the time on Mars as observed from Earth now? It’s like time travel problems in science fiction. When is now; when was then?

Winter lingered so long in the lap of Spring that it occasioned a great deal of talk.

Our goal in science is to discover universal laws of nature. That pursuit fills me with wonder.

The strange thing about grinding that might surprise many people is that you can grind things and shape them using materials that are generally somewhat softer than the thing you’re grinding and shaping.

The most serious problem facing humankind is climate change. All of these people breathing and burning our atmosphere has led to an extraordinarily dangerous situation.

It fills me with joy to know that we can pursue these answers. It is an astonishing thing that we are — you and I are one of the ways the universe knows itself.

Unlike science, creationism cannot predict anything, and it cannot provide satisfactory answers about the past.

People get a lot out of being religious. They have strong senses of community and mutual support. So, what’s not to love [there]?

Think how fortunate we are to know this much. But think also of all that’s yet to be discovered. Here’s hoping the deep answers to the deep questions-from the nature of consciousness to the origin of life-will be found in not too much more time.

Apparently there is redundancy in memory: You store the same memory in different parts of your brain for accessing at different speeds. That speed would depend on the frequency of use and the importance of the knowledge.

There’s nothing I believe in more strongly than getting young people interested in science and engineering, for a better tomorrow, for all humankind.

Religion is a completely different thing from the claim that the Earth is six thousand years old. That’s just crazy.

Speaking of human computers, there is a guy named Art Benjamin, he’s a human calculator. He says it’s a skill he learned as a kid. Now he’s a math professor at Harvey Mudd. He can find the square root of a six digit number in a few seconds. Practice.

I abandoned my religious teachings after I read the Bible twice – cover to cover. It took me a couple of years.

If the Earth gets hit by an asteroid, it’s game over. It’s control-alt-delete for civilization.

The natural world is a package deal; you don’t get to select which facts you like and which you don’t.

Don’t be discouraged by writer’s block. Writer’s block just means you need to listen to other music.

The late ’90s were a really bad time for people trying to be rock stars, you know what I mean? It seemed like everyone was a one-hit wonder on the radio.

So the prelude to ‘Ghostfacers!’ is the Ghostfacers going, ‘Yeah, those fat-cat writers, we’ve got a show that’s better than that bullshit anyway.’ I mean, that’s pretty cool in the world of metanarrative, which is, I have to admit, one of my abiding passions.

I think most people, even if they say they hate horror movies, there’s that feeling you get inside that you love.

The second time I was there I met Marcel Duchamp, and we immediately fell for each other. Which doesn’t mean a thing because I think anybody who met Marcel fell for him.

It just means that if someone hates you, they still have feelings for you. If they really didn’t care about you, they’d just forget about you. They wouldn’t even waste the time hating you.

In most cases being a good boss means hiring talented people and then getting out of their way.

To have ego means to believe in your own strength. And to also be open to other people’s views. It is to be open, not closed. So, yes, my ego is big, but it’s also very small in some areas. My ego is responsible for my doing what I do – bad or good.
