Quote by Joseph-Louis Lagrange

"The true system of the world has been recognised, last, in the masterly work of Newton on the Mathematical Principles of Natural Philosophy."

"I have turned my mind to the great problems of mathematics."

"The study of mathematics is like climbing a high mountain."

"Nature laughs at the difficulties of calculus."

"Success comes to those who never give up."

"Success is measured by happiness, not money."

"You make your own luck in this world."

"You have to be organized to be successful in anything."
