I never got into 'Star Wars.' Maybe because they made no attempt to portray real physics. At all.

I'm an educator, and I'm a scientist, and I speak what is objectively true. And if that offends you, I can try to have a conversation with you to ask why it offends you, and tell you why objective truth should not offend you because that's how the world works.

I can tell you about the universe, but she feels it; and when you feel the universe, it has a whole other meaning to you. Otherwise, you just put a Wiki page on camera. You can learn something, but it won't mean anything to you later on.

You gotta be a good sport! So when I would lose, I would say, "That guy was better than I was; what do I have to do to be better next time?"

For centuries, magicians have intuitively taken advantage of the inner workings of our brains.

But to carve the Grand Canyon, Earth required millions of years. To excavate Meteor Crater, the universe, using a sixty-thousand-ton asteroid traveling upward of twenty miles per second, required a fraction of a second. No offense to Grand Canyon lovers, but for my money, Meteor Crater is the most amazing natural landmark in the world.

In the end, it's the people who are curious who change the world.
