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.

You and I are made of stardust. We are the stuff of exploded stars. We are therefore, at least 1 way that the Universe knows itself. That, to me, is astonishing.

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.

Along with the evidence of common sense, researchers have proven scientifically that humans are all one people. We're a lot like dogs in that regard. If a Great Dane interacts (can we say interact?) with a Chihuahua, you get a dog.

If you look back on all the teachers that you liked, I am sure you will find they were very entertaining.

The strange thing about grinding that might surprise many people is that you can grind things and shape them using materials that are generally somewhat softer than the thing you're grinding and shaping.

Science is the best thing humans beings have ever come up with. And if it isn't, science will fix it.
