"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 letters
in which it is composed.
It is written in the language of mathematics,
and its characters are triangles, circles, and other
without which it is humanly impossible
to understand a single word of it.”
Galileo Galilei, 1623
These words come from a poster in the Galileo Museum in Florence, Italy -- a place I had the good fortune to visit recently. Here are two photos from that visit.
