What is the metaphor of butterfly effect?

Butterfly effect means that in a dynamic system, small changes in initial conditions can drive a long-term huge chain reaction of the whole system.

This is a chaotic phenomenon.

The development of everything has definite numbers and variables. The development process of things has laws to follow, but there are also unpredictable "variables", which are often counterproductive. A small change can affect the development of things, indicating that the development of things is complex.

Theoretical origin of butterfly effect;

A butterfly in the tropical rain forest of Amazon River basin in South America can trigger a tornado in Texas within two weeks with an occasional flap of its wings.

The reason is that the movement of butterfly flapping its wings changes the surrounding air system and produces a weak airflow, which in turn will cause corresponding changes in the surrounding air or other systems, thus causing a chain reaction.

Eventually, it will lead to great changes in other systems. He called it chaos. Of course, the "butterfly effect" is mainly a metaphor about chaos. It is also the true reaction of the butterfly effect. An insignificant little gesture can cause a series of great reactions.
