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."

"Every day is a new opportunity."

"Hope is what gets us through difficult times."

"I'm not your enemy, kid. I'm trying to save you."

"Redemption is a long road."
