Nature, The Golden Ratio and Fibonacci Numbers

example of golden ratio in nature

This gives rise to branches, whose number follow the Fibonacci progression. This implies that, at each branching node, the ratio of new branches to old is 1.618. In geometry, golden ratios appears in many shapes — including rectangles, triangles and squares inside circles, and the pentagon. For example, if you take a square and multiple one side by 1.618 (the golden ratio), you will get a rectangle with perfectly harmonious proportions — called a golden rectangle.

It’s important to note that the spiritual meaning and interpretations of the Fibonacci spiral are not based on scientific evidence, but rather on cultural, philosophical and personal beliefs. As a professional in the design industry, I have always been passionate about recognizing and celebrating excellence in design, and the opportunity to be a part of the awards process was truly a… A person can find the next number in the list by adding the last two numbers together. If a person divides a number in the list by the number that came before it, this ratio comes closer and closer to the golden ratio. However, it’s also seen in largely abstract places, like the point in a black hole where the heat changes from positive to negative. Its consistent presence could signify the Golden Ratio as a fundamental constant of nature — which might explain why our brains seem hard-wired to respond better to visuals that follow the Golden Ratio.

Composers Who Used the Golden Ratio

To make the ratio, we take two consecutive numbers n and n+1 from the Fibonacci Sequence and divide n+1 with n – the bigger number with the smaller number. As with numerological superstitions such as famous people dying in sets of three, sometimes a coincidence is just a coincidence. Thanks to books like Dan Brown’s The Da Vinci Code, the golden ratio has been elevated to almost mystical levels in popular culture. However, some mathematicians have stated that the importance of this ratio is wildly exaggerated. In computer science, the Fibonacci sequence is used to analyze the time complexity of algorithms. The Fibonacci sequence is used to represent the number of recursive calls made by an algorithm, which helps to determine the time complexity of the algorithm.

Each cone consists of pairs of alternating whorls, each oriented in the opposite direction to the other whorl. The ratio of the turn of each pod and the ratio between the number of pods in successive whorls is the golden ratio, i.e., 1.618. The Fibonacci sequence can also be seen in the way tree branches form or split.

Fibonacci Patterns

Researchers have also found evidence of the golden spiral and golden ratio is many other plants, including fiddleheads — the the curled up fronds of a young fern — daisies and spiral aloe vera. Looking at the golden ratio in nature brings mathematics to life  — quite literally — and it is far from boring. It becomes relatively easy to understand this mystical mathematical constant when we break it down.

What are examples of the golden ratio in plants?

For trees, poplar is 34.4°, and peach is 55.6°. These angles (55.6° and 34.4°) are the golden section of 90°. The golden section also exists in some lobed leaves, the lobe angles of Korean arborvitae and cypress are both 34.4°. The ratio between two pine needles is 0.618, as well as the ratio of leaf venation.

This shape, a rectangle in which the ratio of the sides a/b is equal to the golden mean (phi), can result in a nesting process that can be repeated into infinity — and which takes on the form of a spiral. Finally, our favorite example of the golden ratio in nature is among some of our hardest workers on the planet — bees. Many researchers and authors believe that the elliptical honeycomb of a hive is also related to the golden ratio. If bees become extinct, humans and many other examples of the golden ratio in nature will be at serious risk of extinction, too.

Golden Ratio and Art

There are many examples of the golden ratio in nature — yet many people have no idea what it is or how to appreciate the planet’s stunning geometry. This might be because the US as a nation, does not appear to excel in the subject of mathematics. One of the most amazing examples example of golden ratio in nature of Golden Ratio is found within the human DNA structure. This can be seen in a single DNA cross section that reveals the DNA double helix forms a decagon shape. This is a combination of two pentagons, rotated 36 degrees from each other, forms the DNA double helix.

A main trunk will grow until it produces a branch, which creates two growth points. Then, one of the new stems branches into two, while the other one lies dormant. In other situations, the ratio exists because that particular growth pattern evolved as the most effective. In plants, this may mean maximum exposure for light-hungry leaves or maximized seed arrangement. Look at the array of seeds in the center of a sunflower and you’ll notice they look like a golden spiral pattern. Amazingly, if you count these spirals, your total will be a Fibonacci number.

Do all plants follow the golden ratio?

The sequence goes like this: 1, 1, 2, 3, 5, 8, 13, 21, 34, etc. The ratio of two neighboring Fibonacci numbers is an approximation of the golden ratio. Petals and leaves are often found in this distribution, although not every plant behaves like this so we cannot claim that it's a universal property.
