"We are made of star stuff."

"Science is a way of thinking much more than it is a body of knowledge."

"The most incomprehensible thing about the world is that it is comprehensible."

"The best part of living is knowing you survived."

"The world needs heroes."

"Life is too short to live poorly."

"I'd rather be an optimist and be wrong than a pessimist and be right"
