Philosophy is written in this grand book, the universe, which stands continually open to our gaze.
But the book cannot be understood unless one first learns to comprehend the language and read the characters in which it is written.
It is written in the language of mathematics, and its characters are triangles, circles, and other geometric figures without which it is humanly impossible to understand a single word of it;
without these one is wandering in a dark labyrinth.
