Not enough books focus on how a culture responds to radically new ideas or discovery. Especially in the biography genre, they tend to focus on all the sordid details in the life of the person who made the discovery. I find this path to be voyeuristic but not enlightening.
Venus has a runaway greenhouse effect. I kind of want to know what happened there because we're twirling knobs here on Earth without knowing the consequences of it. Mars once had running water. It's bone dry today. Something bad happened there as well.
I'm on a crusade to get movie directors to get their science right because, more often than they believe, the science is more extraordinary than anything they can invent.
'Cosmos' is an occasion to bring everything that I have, all of my capacity to communicate. We may go to the edge of the universe, but we're going to land right on you: in your heart, in your soul, in your mind. My goal is to have people know that they are participants in this great unfolding cosmic story.
If you're going to lead a space frontier, it has to be government; it'll never be private enterprise. Because the space frontier is dangerous, and it's expensive, and it has unquantified risks. And under those conditions, you cannot establish a capital-market evaluation of that enterprise. You can't get investors.
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.
Keep in mind that if you take a tour through a hospital and look at every machine with on and off switch that is brought into the service of diagnosing the human condition, that machine is based on principles of physics discovered by a physicist in a machine designed by an engineer.
There are a lot of things you can do in space, and space essentially is unlimited resources. We are climbing over ourselves here looking for the next source of energy. The universe has an unlimited source of energy.
I was transformed by picking up a pair of binoculars and looking up, and that's hard to do for a city kid because when you look up you just see buildings - and really, your first thought is to look in people's windows. So to look out of the space - out of living space - and look up to the sky, binoculars go far, literally and figuratively.
It turns out our brain is sensitive, maybe too sensitive, to motion. It's a survival mechanism.
In the animal kingdom, one of the keys to survival is to outwit your enemies. And when you're surrounded by carnivores, one of the best strategies is to fade into the background and disappear.
It's actually the minority of religious people who rejects science or feel threatened by it or want to sort of undo or restrict the... where science can go. The rest, you know, are just fine with science. And it has been that way ever since the beginning.
So the history of discovery, particularly cosmic discovery, but discovery in general, scientific discovery, is one where at any given moment, there's a frontier. And there tends to be an urge for people, especially religious people, to assert that across that boundary, into the unknown, lies the handiwork of God. This shows up a lot.
The history of exploration has never been driven by exploration. But Columbus himself was a discoverer. So was Magellan. But the people who wrote checks were not. They had other motivations.
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.
The cross pollination of disciplines is fundamental to truly revolutionary advances in our culture.
I can't tell you how many people say they were turned off from science because of a science teacher that completely sucked out all the inspiration and enthusiasm they had for the course.
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's a lot to do in space. I want to learn more about the greenhouse effect on Venus, about whether there was life on Mars, about the environment in which Earth and the Sun is immersed, the behavior of the Sun.
