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."

"A man's home is his castle."

"Family is everything to me."

"Life's greatest treasure is the love of family."

"A woman's place is in the home... making it a happy one."
