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."

"Some battles are worth fighting."

"Sometimes you have to become the monster to stop the monsters."

"Skynet sent me back through time to kill you."

"War teaches us the value of peace."
