“In mathematics you don't understand things. You just get used to them.”

John von Neumann

“Pure mathematics is, in its way, the poetry of logical ideas.”

Albert Einstein

“The mathematical sciences particularly exhibit order, symmetry, and limitation; and these are the greatest forms of the beautiful.”

Aristotle

“But there is another reason for the high repute of mathematics: it is mathematics that offers the exact natural sciences a certain measure of security which, without mathematics, they could not attain.”

“University President: Why is it that you physicists always require so much expensive equipment? Now the Department of Mathematics requires nothing but money for paper, pencils, and erasers...and the Department of Philosophy is better still. It doesn't even ask for erasers.”

Isaac Asimov

“Mathematics would certainly have not come into existence if one had known from the beginning that there was in nature no exactly straight line, no actual circle, no absolute magnitude.”

Friedrich Nietzsche

“There are things which seem incredible to most men who have not studied mathematics.”
