“Philosophy is written in this great book, which is continuously open in front of us (I am talking about Universe), but it cannot be understood if before we do not learn to understand the language and to know the letters in which it is written. It is written in mathematical language and the letters are triangles, circles and other geometrical figures: without such means it is impossible to understand a word of it; without them we would go around in vain as in a dark labyrinth.”
