The Human Hand
Your hand shows Phi and the Fibonacci Series
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! We'll need a few Golden Section / Fibonacci building blocks:
Each line is 1.61804... times longer than the one before it. (Conversely, a section
drawn at 0.61804 (or 61.8%) of each line equals the length of the one before it.)
Let's start with something simple. Take your hand off your keyboard or mouse and look
at the proportions of your index finger.
Hold your hand up to the screen. Don't be shy!
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!
The ratio of your forearm to hand is Phi
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.
