If people are prepared to eat locally and seasonally, then they probably do pretty well in terms of environmental impact.

Google has withdrawn from China, arguing that it is no longer willing to design its search engine to block information that the Chinese government does not wish its citizens to have. In liberal democracies around the world, this decision has generally been greeted with enthusiasm.

Most of the robots being developed for home use are functional in design - Gecko's homecare robot looks rather like the Star Wars robot R2-D2. Honda and Sony are designing robots that look more like the same movie's 'android' C-3PO.

The essence of true friendship is to make allowance for another's little lapses.

There is no cure for the pride of a virtuous nation but pure religion.

Forgiveness is the final form of love.

The sad duty of politics is to establish justice in a sinful world.

God grant me the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference.

God, give us grace to accept with serenity the things that cannot be changed, courage to change the things which should be changed and the wisdom to distinguish the one from the other.

The final wisdom of life requires not the annulment of incongruity but the achievement of serenity within and above it.

Goodness, armed with power, is corrupted; and pure love without power is destroyed.

Nothing we do, however virtuous, can be accomplished alone; therefore we are saved by love.

Nothing that is worth doing can be achieved in a lifetime; therefore we must be saved by hope.

If we survive danger it steels our courage more than anything else.

Life is a battle between faith and reason in which each feeds upon the other, drawing sustenance from it and destroying it.

Nothing which is true or beautiful or good makes complete sense in any immediate context of history; therefore we must be saved by faith.

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.

In science, if you don't do it, somebody else will. Whereas in art, if Beethoven didn't compose the 'Ninth Symphony,' no one else before or after is going to compose the 'Ninth Symphony' that he composed; no one else is going to paint 'Starry Night' by van Gogh.

If you get asteroids about a kilometer in size, those are large enough and carry enough energy into our system to disrupt transportation, communication, the food chains, and that can be a really bad day on Earth.

I'm not as famous as Stephen Hawking, but certainly in the U.S., I have a very high profile for a scientist. It is an awesome responsibility, one that I don't shoulder lightly.

The caricature of science is that we hold tight to the theories we have, and shun challenges to them. That's just not true. In fact, we hold our highest rewards for those scientists who can prove others wrong. And by the way, they are famous in their own lifetimes. We don't wait until they're dead.

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

Humans aren't as good as we should be in our capacity to empathize with feelings and thoughts of others, be they humans or other animals on Earth. So maybe part of our formal education should be training in empathy. Imagine how different the world would be if, in fact, that were 'reading, writing, arithmetic, empathy.'

There is no greater education than one that is self-driven.

One of my great laments is that education today seems to have... be less about passion and more about process, more about tactic or technique.

Any time scientists disagree, it's because we have insufficient data. Then we can agree on what kind of data to get; we get the data; and the data solves the problem. Either I'm right, or you're right, or we're both wrong. And we move on. That kind of conflict resolution does not exist in politics or religion.

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.

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.

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.

If your ego starts out, 'I am important, I am big, I am special,' you're in for some disappointments when you look around at what we've discovered about the universe. No, you're not big. No, you're not. You're small in time and in space. And you have this frail vessel called the human body that's limited on Earth.

Once you have an innovation culture, even those who are not scientists or engineers - poets, actors, journalists - they, as communities, embrace the meaning of what it is to be scientifically literate. They embrace the concept of an innovation culture. They vote in ways that promote it. They don't fight science and they don't fight technology.

Science literacy is the artery through which the solutions of tomorrow's problems flow.

The very nature of science is discoveries, and the best of those discoveries are the ones you don't expect.

Science is basically an inoculation against charlatans.

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.

There is no science in this world like physics. Nothing comes close to the precision with which physics enables you to understand the world around you. It's the laws of physics that allow us to say exactly what time the sun is going to rise. What time the eclipse is going to begin. What time the eclipse is going to end.

Part of what it is to be scientifically-literate, it's not simply, 'Do you know what DNA is? Or what the Big Bang is?' That's an aspect of science literacy. The biggest part of it is do you know how to think about information that's presented in front of you.

Science is an enterprise that should be cherished as an activity of the free human mind. Because it transforms who we are, how we live, and it gives us an understanding of our place in the universe.

One of the greatest features of science is that it doesn't matter where you were born, and it doesn't matter what the belief systems of your parents might have been: If you perform the same experiment that someone else did, at a different time and place, you'll get the same result.

You can't train kids in a world where adults have no concept of what science literacy is. The adults are gonna squash the creativity that would manifest itself, because they're clueless about what it and why it matters. But science can always benefit from the more brains there are that are thinking about it - but that's true for any field.

What are we promoting in society? Well-behaved automatons that spew back what they learned in a book. That's not science. You can get a parrot to do that.

Carl Sagan spoke fluently between biology and geology and astrophysics and physics. If you move fluently across those boundaries, you realize that science is everywhere; science is not something you can step around or sweep under the rug.

Innovations in science and technology are the engines of the 21st-century economy; if you care about the wealth and health of your nation tomorrow, then you'd better rethink how you allocate taxes to fund science. The federal budget needs to recognize this.

Asteroids have us in our sight. The dinosaurs didn't have a space program, so they're not here to talk about this problem. We are, and we have the power to do something about it. I don't want to be the embarrassment of the galaxy, to have had the power to deflect an asteroid, and then not, and end up going extinct.

Ever since the Industrial Revolution, investments in science and technology have proved to be reliable engines of economic growth. If homegrown interest in those fields is not regenerated soon, the comfortable lifestyle to which Americans have become accustomed will draw to a rapid close.

It was unthinkable not long ago that a biologist or paleontologist would be at the same conference as an astrophysicist. Now we have accumulated so much data in each of these branches of science as it relates to origins that we have learned that no one discipline can answer questions of origins alone.

If God is the mystery of the universe, these mysteries, we're tackling these mysteries one by one. If you're going to stay religious at the end of the conversation, God has to mean more to you than just where science has yet to tread.

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.

In nature, when you conduct science, it is the natural world that is the ultimate decider in what is true and what is not.

The partisanship surrounding space exploration and the retrenching of U.S. space policy are part of a more general trend: the decline of science in the United States. As its interest in science wanes, the country loses ground to the rest of the industrialized world in every measure of technological proficiency.
