"The problem in society is not kids not knowing science. The problem is adults not knowing science. They outnumber kids 5 to 1, they wield power, they write legislation. When you have scientifically illiterate adults, you have undermined the very fabric of what makes a nation wealthy and strong."
"If you get asteroids about a kilometer in size, those are large enough and carry enough energy into our system to disrupt transportation, communication, the food chains, and that can be a really bad day on Earth."

"Dreams about the future are always filled with gadgets."
"The good thing about science is that it's true whether or not you believe in it."
"Claiming there is no other life in the universe is like scooping up some water, looking at the cup and claiming there are no whales in the ocean."
"Knowing how to think empowers you far beyond those who know only what to think."
"The problem, often not discovered until late in life, is that when you look for things like love, meaning, motivation, it implies they are sitting behind a tree or under a rock.

For me, I am driven by two main philosophies, know more today about the world than I knew yesterday. And along the way, lessen the suffering of others. You'd be surprised how far that gets you."
