Phi

Phi is a FUNCTION—the primordial algorithm.

The ratio of a : a+b can be written as 1 : 1.618. Phi (Φ) recurs infinitely and is also known as dynamic, because in a sense it’s alive. Unlike the Fibonacci spiral, you will NEVER see a golden mean spiral, nor can you graph it. Like a vibration or a fractal it may be felt or experienced, but because it is an infinite spiral it is not bound by finite mathematics.

There are many ways to construct the golden ratio geometrically. The figure above is rather special however, because it reveals the golden ratio within the vesica piscis.

It may help to think of Φ as the divine drummer, pulsing out the base beat of the universe like a sacred heart.
