You cannot teach a man anything, you can only help him find... - Galileo Galilei

"By denying scientific principles, one may maintain any paradox."

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

"I have never met a man so ignorant that I couldn't learn something from him."

"The sun, with all those planets revolving around it and dependent on it, can still ripen a bunch of grapes as if it had nothing else in the universe to do."

"By denying scientific principles, one may maintain any paradox."
