Examples of natural patterns include waves, cracks, or lightning. Man-made patterns are often used in design and can be abstract, such as those used in mathematics, science, and language. In architecture and art, patterns can be used to create visual effects on the observer.

What are examples of patterns?

Patterns in nature are visible regularities of form found in the natural world. These patterns recur in different contexts and can sometimes be modelled mathematically. Natural patterns include symmetries, trees, spirals, meanders, waves, foams, tessellations, cracks and stripes.

What is a code pattern?

In software engineering, a design pattern is a general repeatable solution to a commonly occurring problem in software design. A design pattern isn’t a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations.
