A butterfly in a tropical rainforest in the Amazon River Basin, occasionally a few wings, two weeks, may cause a tornado in Texas, USA. This is the "Butterfly Effect" feeling seems to be similar to the domino effect, the butterfly effect, the result of the development of things, the initial conditions have extremely sensitive dependence, and the minimum deviation of the initial conditions will cause great differences. An illustration of a folk rhyme to the butterfly effect, this folk says:
Lost a nail, broken a hoof; broken a hoof, folding a horse; folding a horse, hurting a knight; hurt a knight, lost a battle; lost A battle, killing an empire. It seems a bit incredible but the truth is true, some seemingly very small things may cause very serious consequences, so prevent micro-duplexing should be achieved in anything.
