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."

"The pen is mightier than the sword."

"Literature opens the mind to new worlds"

"The interesting thing about books is that they're made of words."

"Literature captures the essence of what it means to be human."
