There is no example of someone reading their scripture and saying, 'I have a prediction about the world that no one knows yet, because this gave me insight. Let's go test that prediction,' and have the prediction be correct.
All tweets are tasty. Any tweet anybody writes is tasty. So, I try to have each tweet not simply be informative, but have some outlook, some perspective that you might not otherwise had.
If the United States commits to the goal of reaching Mars, it will almost certainly do so in reaction to the progress of other nations - as was the case with NASA, the Apollo program, and the project that became the International Space Station.
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.
People credit me for making the universe interesting when in fact the universe is inherently interesting, and I'm merely revealing that fact. I don't think I'm anything special for this to happen.

For me, I am driven by two main philosophies: know more today about the world than I knew yesterday and lessen the suffering of others. You'd be surprised how far that gets you.
Kids are never the problem. They are born scientists. The problem is always the adults. They beat the curiosity out of kids. They outnumber kids. They vote. They wield resources. That's why my public focus is primarily adults.
I critique market-based medicine not because I haven't seen its heights but because I've seen its depths.
The thing about rights is that in the end you can't prove what should be considered a right.
I would say that, intellectually, Catholicism had no more impact on me than did social theory.
I think that looking forward it's easy to imagine more constructive help for Haiti.
I feel it's part of my job to make the problems of the poor compelling.
Some people talk about Haiti as being the graveyard of development projects.
If you compare NASA's annual budget to explore the heavens, that one year budget would fund NOAA's budget to explore the oceans for 1,600 years.
No man ever looks at the world with pristine eyes. He sees it edited by a definite set of customs and institutions and ways of thinking.
A man's indebtedness is not virtue; his repayment is. Virtue begins when he dedicates himself actively to the job of gratitude.
