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."

"Hard work never killed anybody."

"Work with purpose and integrity."

"Hard work pays off in the end."

"A man's gotta do what a man's gotta do."
