There are many examples of the Divine Proportion found throughout the design of the universe and everything in it, but let’s take a look at one of the most important things first: You! The human body is based on Phi and 5.
Take your hand and look at the proportions of your index finger. Each section of your index finger, from the tip to the base of the wrist, is larger than the preceding one by about the Fibonacci ratio of 1.618, also fitting the Fibonacci numbers 2, 3, 5 and 8. By this scale, your fingernail is 1 unit in length.
Curiously enough, you also have 2 hands, each with 5 digits, and your 8 fingers are each comprised of 3 sections. All Fibonacci numbers!
Your hand creates a golden section in relation to your arm, as the ratio of your forearm to your hand is also 1.618, the Divine Proportion.
Even your feet show phi The foot has several proportions based on phi lines, including: The middle of the arch of the foot, the widest part of the foot, the base of the toe line and big toe the top of the toe line and base of the “index” toe.
The DNA molecule, the program for all life, is based on the golden section. It measures 34 angstroms long by 21 angstroms wide for each full cycle of its double helix spiral. 34 and 21, of course, are numbers in the Fibonacci series and their ratio, 1.6190476 closely approximates phi, 1.6180339.
B-DNA has spirals in phi proportions. DNA in the cell appears as a double-stranded helix referred to as B-DNA.This form of DNA has a two groove in its spirals, with a ratio of phi in the proportion of the major groove to the minor groove, or roughly 21 angstroms to 13 angstroms.
