Butterfly Effect Butterfly Effect is that Meteorologist Lorenz is raised in 1963. It is worth: A butterfly in a tropical rainforest in the South America Amazon River Basin, occasionally a few wings, may cause a tornado in two weeks later. The reason is that the movement of the butterfly wings leads to changes in the air system around them, and causes weak airflow production, while the production of weak airflows will cause corresponding changes in air or other systems, thereby causing a chain to reflect, Eventually lead to great changes in other systems. This effect illustrates that the results of the development of things have extremely sensitive dependence on the initial conditions, and the extremely small deviation of the initial conditions will cause great differences in the results. "Butterfly Effect" is used in the sociological community to explain: a bad minor mechanism, if not in time to guide, adjust, will bring a very harm to society, and the drama is called "tornado" or "storm"; a good Tiny mechanism, as long as the correct guidance, after a period of efforts, will have a sensational effect, or called "revolution".
