"Humor is everywhere in that there's irony in just about anything a human does."
"The more you find out about the world, the more opportunities there are to laugh at it."
"I've always loved airplanes and flight. The space program was really important to me as a kid. I still have a photo of Armstrong and Aldrin on the moon in my living room."
"When we see the shadow on our images, are we seeing the time 11 minutes ago on Mars? Or are we seeing the time on Mars as observed from Earth now? It's like time travel problems in science fiction. When is now; when was then?"
"Winter lingered so long in the lap of Spring that it occasioned a great deal of talk."
"A two-and-a-half-year-old is pretty experienced at making a mess, anyway."
"As you may know, I am a mechanical engineer."
"If you look back on all the teachers that you liked, I am sure you will find they were very entertaining."
"Science rules!"
"I always liked show biz and got to make a few training films at Boeing."
"Climate change is happening, humans are causing it, and I think this is perhaps the most serious environmental issue facing us."
"NASA is an engine of innovation and inspiration as well as the world's premier space exploration agency, and we are well served by politicians working to keep it that way, instead of turning it into a mere jobs program, or worse, cutting its budget."
"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."
"But investment in space stimulates society, it stimulates it economically, it stimulates it intellectually, and it gives us all passion."
"Everyone, red state, blue state, everyone supports space exploration."
"You stop planetary exploration, those people who do that extraordinary work are going to have to go do something else."

"Evolution is the fundamental idea in all of life science - in all of biology."
"It's important that our children are raised to be educated, well-rounded tax-paying citizens that understand the importance of technology and science."
"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."
"Teaching creationism in science class as an alternative to evolution is inappropriate."
"Unlike science, creationism cannot predict anything, and it cannot provide satisfactory answers about the past."
"I change my socks often, because I had bad bouts of athlete's foot fungus infections as a kid. I may be able to change socks less frequently and not get the fungus. But, I'd rather not run the test to determine just how infrequently I could change socks. I don't feel superstitious about it."
"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."
"My father was a very good Boy Scout. He was very skilled with knots, and he showed me how to tie a bow tie."
