"Doubt is not weakness in science - it is the engine of progress."
"Doubt is not weakness in science - it is the engine of progress."
"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."
