“The essence of mathematics is not to make simple things complicated, but to make complicated things simple.”

S. Gudder

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

Albert Einstein

“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.”

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

Aristotle

“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

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

John von Neumann

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