Bill Nye

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

Everybody who's a physician, who makes vaccines, who wants to find the cure for cancer. Everybody who wants to do any medical good for humankind got the passion for that before he or she was 10.

What makes the United States great, the reason people wanted to live in the United States, move here still, is because of our ability to innovate.

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.

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.

If the Earth gets hit by an asteroid, it's game over. It's control-alt-delete for civilization.

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.

The Earth is not 6,000 or 10,000 years old. It's not. And if that conflicts with your beliefs, I strongly feel you should question your beliefs.

The Big Bang banged, and for some reason we’re here. And that’s astonishing. And that we can understand that, that’s the most astonishing.

I understand that you take the Bible, as written in English, translated many many times over the last three millennia as to be a more accurate, more reasonable assessment of the natural laws we see around us than what I and everybody in here can observe. That, to me, is unsettling.

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

I say to the grownups, if you want to deny evolution and live in your world, that's completely inconsistent with the world we observe, that's fine. But don't make your kids do it. Because we need them. We need scientifically literate voters and taxpayers for the future. We need engineers that can build stuff and solve problems.

If you want grown-ups to recycle, just tell their kids the importance of recycling, and they'll be all over it.

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?

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.

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

You stop planetary exploration, those people who do that extraordinary work are going to have to go do something else.

To leave the world better than you found it, sometimes you have to pick up other people's trash.

Science is the best idea humans have ever had. The more people who embrace that idea, the better.

Science is the key to our future, and if you don't believe in science, then you're holding everybody back.

Humor is everywhere in that there's irony in just about anything a human does.
