How many wings can a butterfly flap its wings cause a tornado?
Do you know what the butterfly effect is?
The butterfly effect is one of the important theories summarized in the process of human understanding of nature, and it is also the main means of describing uncertain phenomena.

The most common illustration of the butterfly effect is: "A butterfly in the Amazon rainforest of South America, occasionally flapping its wings a few times, can cause a tornado in Texas two weeks later." "The reason for this is that the movement of the butterfly flapping its wings causes the air system around it to change and produce a weak airflow, and the weak airflow will cause corresponding changes in the surrounding air or other systems, which will cause a chain reaction, which eventually leads to great changes in other systems."
The butterfly effect was first proposed and elaborated by the American meteorologist Edward Lorentz, who called it chaos science.
The real reaction of the butterfly effect refers to the fact that a small, inconspicuous action can cause a series of huge reactions. A small error has huge consequences over time. In a dynamical system, small changes in initial conditions can drive a long-term huge chain reaction of the entire system.
For example, the bankruptcy of a bank in the United States - wall street financial storm - the global economic crisis.
There is also an American movie called "The Butterfly Effect", which tells that the protagonist has damaged his original perfect life because of his childhood memories.
The butterfly effect is called a chaotic phenomenon, because it shows that there are fixed numbers and variables in the development of any thing, and the development trajectory of things in the process of development has a regularity to follow, and there are also unpredictable "variables", which often backfire, and a small change can affect the development of things, confirming that the development of things is complex.
The word "chaos" is a mythical term that is widely used around the world, and its meaning varies greatly around the world, and in Greek mythology, chaos is the god who gave birth to the world.
In many myths, the world originated from chaos, and at first the heavens and the earth were joined together, that is, in a state of chaos, until the Creator God separated them.
