Scientists in different disciplines don't speak the same language. They publish in different journals. It's like the United Nations: You come together, but no one speaks the same language, so you need some translators.
-
I'm often asked - and occasionally in an accusatory way - 'Are you atheist?' And it's like, 'You know, the only 'ist' I am is a scientist, all right?' I don't associate with movements. I'm not an 'ism.' I just - I think for myself.
-
As history has shown, pure science research ultimately ends up applying to something. We just don't know it at the time.
-
The theory of evolution, like the theory of gravity, is a scientific fact.
-
Physics is the only profession in which prophecy is not only accurate but routine.
-
I'm perennially intrigued how people who lead largely evidence-based lives can, in a belief-based part of their mind, be certain that an invisible, divine entity created an entire universe just for us, or that the government is stockpiling space aliens in a secret desert location.
-
We didn't go to the moon to explore or because it was in our DNA or because we're Americans. We went because we were at war and we felt a threat.
-
All I can say is, the universe is in a good shape, it's earth that has all the problems.
-
Kids should be allowed to break stuff more often. That's a consequence of exploration. Exploration is what you do when you don't know what you're doing.
-
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.
-
The cross pollination of disciplines is fundamental to truly revolutionary advances in our culture.
-
You've never seen me debate anybody. On anything. Ever. My investment of time, as an educator, in my judgment, is best served teaching people how to think about the world around them. Teach them how to pose a question. How to judge whether one thing is true versus another. What the laws of physics say.
-
The first colony on Mars is not going to be built by a private company. How are you going to make money? You're not.
-
The history of exploration across nations and across time is not one where nations said, 'Let's explore because it's fun.' It was, 'Let's explore so that we can claim lands for our country, so that we can open up new trade routes; let's explore so we can become more powerful.'
-
I know that the molecules in my body are traceable to phenomena in the cosmos.
-
The universe is large and old, and the ingredients for life as we know it are everywhere, so there's no reason to think that Earth would be unique in that regard. Whether of not the life became intelligent is a different question, and we'll see if we find that.
-
If Mars formed life, then life on Earth could have been seeded by life on Mars, making every life form on Earth descended from Martians.
-
I always try to get people a different outlook. When you do that, people take ownership of the information. They don't ever have to reference me because, I'd like to believe as an educator, I'm empowering them to have those thoughts themselves.
-
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.
-
Pretty much every plant and animal alive today is the result of eons of natural cross-breeding.
-
That makes me want to grab people on the street and say, 'have you heard this?'
-
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.
-
All the traditional STEM fields, the science, technology, engineering, and math fields, are stoked when you dream big in an agency such as NASA.
-
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.
