What is a Pattern?
Definition
A pattern is some kind of repeated or regular way something is done.
The Cambridge Dictionary tells us: "a particular way in which something is done, is organized, or happens". https://dictionary.cambridge.org/de/worterbuch/englisch/pattern
You can often see patterns in nature in different contexts. They can include all kinds of forms that can be described mathematically such as symmetries, spirals, tesselations, stripes, or even cracks.
Examples of patterns
Patterns can be observed in nature as if they were designed in a specific way. Many plants and animals follow rules creating certain patterns.
Examples are honeycombs created by bees or the structure of a fern.
Also, objects that are not created by living organisms can follow patterns such as certain rock formations or crystals.
Even behaviour or movement can follow a pattern. This can lead to patterns in the design of a city or dancing patterns.
