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."

"Perseverance is the key to success."

"Don't give up on what you believe in."

"I've been through worse."

"You learn to live with the pain."
