This Week’s Theme: Nautilus
Yesterday we saw a living chambered nautilus, today we see the inside of one. It’s a thing of beauty and symmetry. Here’s where math and nature come together to become fascinating: the shell perfectly represents the golden ratio, also known as the golden mean, phi, and Sacred Geometry.
From GeometryCode.com regarding Sacred Geometry:
This spiral generated by a recursive nest of Golden Triangles (triangles with relative side lengths of 1, phi and phi) is the classic shape of the Chambered Nautilus shell. The creature building this shell uses the same proportions for each expanded chamber that is added; growth follows a law which is everywhere the same. The outer triangle is the same as one of the five “arms” of the pentagonal graphic above.
“Geometry has two great treasures: one is the Theorem of Pythagoras; the other, the division of a line into extreme and mean ratio. The first we may compare to a measure of gold; the second we may name a precious jewel.”
~ Johannes Kepler
