In the tropical rain forest of Amazon River basin in South America, a butterfly occasionally flaps its wings, which may trigger a tornado in Texas within two weeks. The reason is that the movement of butterfly wings leads to the change of the surrounding air system, producing weak airflow, which in turn will cause the corresponding change of the surrounding air or other systems, causing a chain reaction, which will eventually lead to great changes in other systems.

This effect shows that the result of the development of things is extremely sensitive to the initial conditions, and the smallest deviation of the initial conditions will cause great differences in the results.

Sociology uses "butterfly effect" to explain a bad tiny mechanism, which will bring great harm to society if it is not guided and adjusted in time, nicknamed "tornado" or "storm"; A good micro-mechanism, as long as it is guided correctly, will have a sensational effect after a period of efforts, or it will be called a "revolution."

The title of the paper is: Effect Butterfly.
