“My father was a very good Boy Scout. He was very skilled with knots, and he showed me how to tie a bow tie.”

“You're dressed in a tuxedo, you wear a bow tie. A bow tie with a tuxedo is more formal than a straight tie with a tuxedo.”

“Evolution is the fundamental idea in all of life science - in all of biology.”

“The more you find out about the world, the more opportunities there are to laugh at it.”

“Unlike science, creationism cannot predict anything, and it cannot provide satisfactory answers about the past.”

“I've got no problem with anybody's religion. But if you go claiming the Earth is only 10,000 years old, that's just wrong.”

“When Rush Limbaugh says I'm not a scientist, I'm charmed - I smirk.”

“Teaching creationism in science class as an alternative to evolution is inappropriate.”

“Burning carbon-based substances like oil, gas, and especially coal, produces billions of tons of extra carbon dioxide each year. Methane gas from cows and pigs and other animals on our large farms ends up in the atmosphere as well, trapping more of the sun's energy as heat.”

“We talk about the Internet. That comes from science. Weather forecasting. That comes from science. The main idea in all of biology is evolution. To not teach it to our young people is wrong.”

“If you're an adult and you choose not to believe in science, fine, but please don't prevent your children from learning about it and letting them draw their own conclusions.”

“Tax dollars intended for science education must not be used to teach creationism as any sort of real explanation of nature, because any observation or process of inference about our origin and the nature of the universe disproves creationism in every respect.”

“If you have this idea that the earth is only 6,000 years old, you are denying, if you will, everything that you can touch and see. You're not paying attention to what's happening in the universe around you.”

“But investment in space stimulates society, it stimulates it economically, it stimulates it intellectually, and it gives us all passion.”

“You can believe what you want religiously. Religion is one thing, but science, provable science, is something else.”

“Evolution is a theory, and it's a theory that you can test. We've tested evolution in many ways. You can't present good evidence that says evolution is not a fact.”

“I like to regard myself as someone who's capable of critical thought, that is to say, who can evaluate claims.”

“I hope climate science becomes the big thing. And then what I want is electrical engineers to solve the world's energy problems, energy distribution problems. I want mechanical engineers to make better transportation systems. I want chemical engineers to develop better solar panels, and so on.”

“If NASA is to reach beyond the Moon and someday reach Mars, it must be relieved of the burden of launching people and cargo to low earth orbit. To do that, we must invest more in commercial spaceflight.”

“Television isn't inherently good or bad. You go to a bookstore, there are how many thousands of books, but how many of those do you want? Five? Television's the same way. If you're going to show people stuff, television is the way to go. Words and pictures show things.”
