“Never change a winning game; always change a losing one.”

But as the cerebellum degrades with age, so does the quality of memories. The memories are there, but they’re not as good.

The world’s going to change climatically. We just want to control the change. We want to have a high quality of life for billions of people as we pass through this era.

The US Navy has several people on every ship that can navigate by the stars. They don’t fool with that.

I stand by my assertions that although you can know what happens to any individual species that you modify, you cannot be certain what will happen to the ecosystem.

NASA is an engine of innovation and inspiration as well as the world’s premier space exploration agency, and we are well served by politicians working to keep it that way, instead of turning it into a mere jobs program, or worse, cutting its budget.

Without an end to the burning of fossil fuels, coal especially, most of us will live shorter lives. I’m hopeful, but very, very concerned.

Tax dollars intended for science education must not be used to teach creationism as any sort of real explanation of nature, because any observation or process of inference about our origin and the nature of the universe disproves creationism in every respect.

My father was a very good Boy Scout. He was very skilled with knots, and he showed me how to tie a bow tie.

If you just take a single human and put him or her in the forest he or she might not do very well without some sort of education which he got or she got from some tribe.

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.

We know about the Detroit offense with Calvin Johnson, the best receiver in the game. If this defense continues to play at this pace, they may have something to say about the NFC North.

Why talk now when so many things have been said without ever giving me a chance to talk?

I’ve never predicted anything. All I have ever said is, that we will do the very best we can.

The trouble with referees is that they know the rules, but they do not know the game.

But here’s the deal: If I were smart, I could figure out curling. If I were even smarter, I could figure out why people would actually watch other people doing it. I have tried. I can’t. I can’t even figure out the object of the game. Is it like darts? I just don’t get it.

The Olympic Games of the Modern Era began in 1896 in the city of Athens.

Every day is a new opportunity. You can build on yesterday’s success or put its failures behind and start over again. That’s the way life is, with a new game every day, and that’s the way baseball is.

My favorite board game is a board game I’m working on right now. It’s a game of Napoleonic era naval warfare, and it’s going to be fun.
