Quote by Leon Lederman

"The effort to understand the universe is one of the very few things that lifts human life a little above the level of farce, and gives it some of the grace of tragedy."

"Science is based on experiment, on a willingness to challenge old dogma."

"Imagination is more important than knowledge. Knowledge is limited; imagination embraces the entire world."

"I believe that every human has a finite number of heartbeats. I don't intend to waste any of mine."

"Education opens doors."

"Education opens doors to endless possibilities."

"I ain't got the education you got, bub."

"You can't put a price on history."
