"Philosophy is written in this vast book, which continuously lies open before our eyes. But it cannot be understood unless we understand the language and recognize the characters in which it is written. It is written in the language of triangles circles, geometrical figures. Without such means, it is impossible for us humans to understand a word of it, and to be without them is to wonder around in vain through a dark labyrinth."
— Galileo Galilei
Italian physicist, astronomer, and philosopher, died January 8, 1642
