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."

"The most important thing is to be curious."

"Life is meant to be lived with passion."

"Life is what happens when you're busy making other plans."

"Life is a journey, not a destination."

"Life's too short for regrets."
