selbstähnlichen
Selbstähnlich is a German word that translates to "self-similar" in English. It describes a property of an object or a set where parts of the object are similar to the whole object, but at different scales. This means that if you zoom in on a self-similar object, you will see smaller versions of the entire object repeated. This characteristic is a fundamental concept in fractal geometry.
Fractals are often self-similar. A classic example is the Koch snowflake. Each side of the Koch snowflake
Self-similarity can be exact or statistical. Exact self-similarity means that the smaller parts are perfect replicas
