The good thing about science is that it’s true whether or not you believe in it.

There’s no greater sign of the failure of the American educational system than the extent to which Americans are distracted by the possibility that Earth might end on December 21, 2012. It’s a profound absence of awareness of the laws of physics and how nature works. So they’re missing some science classes in their training in high school or in college that would empower [them] to understand and to judge when someone else is basically just full of it. Science is like an inoculation against charlatans who would have you believe whatever it is they tell you.

Let us not fool ourselves into thinking we went to the Moon because we are pioneers, or discoverers, or adventurers. We went to the Moon because it was the militaristically expedient thing to do.
