Quote by Galileo Galilei

"In questions of science, the authority of a thousand is not worth the humble reasoning of a single individual."

"All truths are easy to understand once they are discovered; the point is to discover them."

"We cannot teach people anything; we can only help them discover it within themselves."

"Mathematics is the language in which God has written the universe."

"Never underestimate the power of a good laugh."

"Laughter is the best medicine."

"A good laugh is the best medicine."

"Laughter is contagious and wonderful."
