[Natural] philosophy is written in that great book which ever lies
before our eyes I mean the universe but we cannot
understand it if we do not first learn the language and grasp
the symbols in which it is written. It is written in the
language of mathematics, . . . without whose help it is impossible
to comprehend even a single word of it, and without which
one wanders in vain as through a dark labyrinth.
Galileo
