I've spent quality time in the aerospace community, with my service on two presidential commissions, but at heart, I'm an academic. Being an academic means I don't wield power over person, place or thing. I don't command armies; I don't lead labor unions. All I have is the power of thought.
Mars once was wet and fertile. It's now bone dry. Something bad happened on Mars. I want to know what happened on Mars so that we may prevent it from happening here on Earth.
I was an aspiring astrophysicist, and that's how I defined myself, not by my skin color. People didn't treat me as someone with science ambitions. They treated me as someone they thought was going to mug them, or who was a shoplifter.
Darwin's theory of evolution is a framework by which we understand the diversity of life on Earth. But there is no equation sitting there in Darwin's 'Origin of Species' that you apply and say, 'What is this species going to look like in 100 years or 1,000 years?' Biology isn't there yet with that kind of predictive precision.
When you innovate, you create new industries that then boost your economy. And when you create new industries and that becomes part of your culture, your jobs can't go overseas because no one else has figured out how to do it yet.
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.
I claim that space is part of our culture. You've heard complaints that nobody knows the names of the astronauts, that nobody gets excited about launches, that nobody cares anymore except people in the industry. I don't believe that for a minute.
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.
The urge to miniaturize electronics did not exist before the space program. I mean our grandparents had radios that was furniture in the living room. Nobody at the time was saying, 'Gee, I want to carry that in my pocket.' Which is a non-thought.
The very nature of science is discoveries, and the best of those discoveries are the ones you don't expect.
Those who see the cosmic perspective as a depressing outlook, they really need to reassess how they think about the world. Because when I look up in the universe, I know I'm small but I'm also big. I'm big because I'm connected to the universe, and the universe is connected to me.
As an educator, I try to get people to be fundamentally curious and to question ideas that they might have or that are shared by others. In that state of mind, they have earned a kind of inoculation against the fuzzy thinking of these weird ideas floating around out there.
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 you slid Pluto to where Earth is right now, heat from the sun would evaporate that ice, and it would grow a tail. Now that's no kind of behavior for a planet.
When an industry matures, it means it's not advancing, and of course the jobs go overseas. That's the obligation of the multi-national corporation: to put the factory where it can make the widget as cheap as possible. Don't get angry when a corporation does that; we've all bought into this concept. We live in a capitalistic society.
