Wouldn’t it be strange if the same exact pattern was found in different lifeforms throughout the universe? Well, that pattern does exist, and it’s called the Golden Ratio. Also known as the Fibonacci Sequence, the ratio is represented by the Greek letter phi as equalling 1.6180339….it goes on forever. So, who cares? Well, when this ratio is found in architecture, taking the form of a “golden rectangle,” or in nature, on a plant’s spiral or even on a human face, it is supposed to be very aesthetically pleasing. Some even claim that the golden rectangle can be found on the famous painting of Mona Lisa. But, whether Leonardo da Vinci did that intentionally (he was a mathematician), who knows. Sure, it seems wise for painters and architects to include the ratio in their designs. But there’s one artist that used this in their work long before humans—Nature.
Flower petals in nature are often found to be placed at 0.618034 per turn around the stem. This is Nature’s most efficient way of packing the petals on the flower, which allows for the most absorbable sunlight.
The Golden Ratio can also be seen on tree branches, as they form or split off the trunk. When a new branch is formed, it creates two growth points, with one branching off into two more stems and the other remaining dormant. This creates a Fibonacci sequence, where each number is the sum of the two numbers that precede it (0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55).
Even spiral galaxies throughout the universe follow this ratio. The Milky Way has multiple coiled arms, with each being about 12 degree spirals.
A logarithmic spiral, the result of many Golden Rectangles placed within each other, can be repeated into infinity. Snails, nautilus, and even the human cochlea (inside your ear) use the shape of this spiral.
