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."

"A good man treats his wife with respect."

"Kindness always comes back around."

"The power of a smile can change everything."

"Kindness is weakness to some. Not to me."
