Neil deGrasse Tyson — "My brain is too big for my head. I have to wear a special hat."

"The universe is a symphony of strings, and the mind is an instrument that can play them."

"The universe is full of mysteries. And that's a good thing."

"There's no law that says you have to like science to be a scientist. Some people just want to make money."

"Imagine a world where people are judged not by the color of their skin, but by the content of their character, and where the content of their character is measured by how much science they know."

"I'm not saying that science has all the answers. I'm saying that science is the only way we're going to get answers."
