15 Examples Of Maths Patterns In Nature That Will Stun You (Part 1)

Maths presence is also in nature, though it doesn’t sound relevant at all? The following examples will show you how Maths is beautifully shown in nature.

When we talk about Maths, we all think about numbers, books, computers, etc. But do you know that Maths’ presence is also in nature, though it doesn’t sound relevant at all? The following examples will show you how Maths is shown through wonderful things in the natural world.

Snowflakes

This is one of the most popular examples, which shows symmetry in nature. In particular, they indicate six-fold radical symmetry whose arms have identical, elaborate patterns. It’s already challenging for researchers to find out why there is symmetry in plant life as well as in the animal kingdom, and now the phenomenon’s appearance in inanimate objects just further infuriates them.

Snowflakes form when water molecules solidify and arrange themselves naturally. In this process, there are weak hydrogen bonds formed between water molecules. The bonds align in an order to maximize attractive forces while reducing repulsive ones, hence the distinct hexagonal shape.

Interestingly, while a snowflake is completely symmetrical inside itself, there’re no two snowflakes alike. This is because when snowflakes fall from the sky, each of them undergoes different atmospheric conditions, like humidity and wind, which impact on how the flake’s crystals form. At the same time, each of the flake’s arms experiences the same conditions, so they crystallize in the same way.

Sunflowers

These beautiful flowers show radial symmetry, as well as a kind of numerical symmetry, called the Fibonacci sequence. In this sequence, we determine each number by adding together the two numbers preceding it, for example, 1, 2, 3, 5, 8, 13, 21, 24, 55, and so on.

According to flower enthusiasts and scientists, through their counting, the amount of seed spirals of the sunflower adds up to a Fibonacci number. This can also be seen in a lot of plants’ leaves, seeds, and petals and also the reason why we hardly see four-leaf clovers.

As to why sunflowers abide by mathematical rules, scientists’ theory says it’s due to efficiency. Simply speaking, the flowers can hold the most seeds if each seed is separated by an irrational-numbered angle.

Phi, also known as the golden ratio, is the most irrational number. And by dividing any Fibonacci number by the preceding number in the sequence, we will get a number that’s close to Phi. As a result, when a plant follows the Fibonacci sequence, each of its seeds, leaves, petals, or branches will be in an angle corresponding to Phi with another.

Nautilus shell

A nautilus is a cephalopod mollusk that has a spiral shell along with many shot tentacles around its mouth. Nautiluses also show Fibonacci numbers. The shell of a nautilus is grown in a Fibonacci spiral, which tries to maintain the shell’s proportional shape as it grows.

While the proportion of animals and humans’ bodies change as they grow, the nautilus has a growth pattern that helps it maintain the same shape throughout its life. However, not all nautilus follow this pattern but it will be one logarithmic spiral or another. And they don’t even know how their shells grow, they just simply benefit from an advanced evolutionary design.

Pine cones

The seed pods of pinecones arrange in a spiral pattern. They have two spirals, each of which twists upwards in opposing directions. Most of the time, the step number will match a pair of consecutive Fibonacci numbers.

Honeycombs

Mankind has long been amazed by the honeycombs’ hexagonal figures. Bees can instinctively make this, but humans would have to use a compass and ruler if they want to reproduce the structure.

And honeycombs indicates wallpaper symmetry, in which a pattern is repeated until it fully covers a plane. It is believed by mathematicians that bees choose this structure as this the most efficient to store the most honey possible with the smallest amount of wax.

Tree branches

So far, we have talked about the Fibonacci sequence in several examples in nature, and this is another one. A tree’s main trunk grows till it produces a branch, creating two growth points. Then, one of the new stems branches into two, and the others remain dormant. This process repeats with each of the new stems. This pattern also appears in root systems.

Orb web spiders

Orb web spiders are divided into about 5,000 types. They all make almost perfect circular webs with near-equal-distanced radical supports that come out of the middle as well as a spiral they weave to catch preys.

It remains unclear how orb spiders are geometrically inclined. As shown by tests, orbed webs do not catch prey better than irregularly shaped webs.

As per some scientists’ theories, orb webs are made for strength, and radical symmetry helps evenly distribute the force when a prey makes contact with the web, which means fewer rips caused to the thread.
