The Butterfly Effect life rule ----

20 century and the early 60s, meteorologist Edward? Lorenz (EdwardLorenz, Massachusetts Institute of Technology professor, to create a Chaos one) the use of computer "numerical weather prediction" test. He found that, as long as there is little input data, calculate the results will appear very different from "bad tackled solely to a thousand miles" is to describe this situation. This shows, "Numerical Weather Prediction" to some extent also of unpredictability.
Based on this discovery and extensive research, Lorenz December 29, 1972 in Washington, the American Institute of Scientific Development published a speech entitled "Predictability: a butterfly dancing in Brazil could cause a tornado in Texas? . "
speech to the effect: a tropical rain forest in the Amazon River Basin butterfly, occasionally flapping its wings a few, two weeks, may cause a Texas tornado. The reason is, butterfly wings of the movement, leading to changes in air system around, and cause a weak flow generation, while a weak flow generation, it will lead to ambient air or other system to produce changes in the resulting chain of reflection eventually lead to great changes in the weather system.
Lorentz speech and conclusions to the people left a profound impression. From then on, the so-called "butterfly effect" is said to spread rapidly, famously had.
butterfly effect shows the results of development of things, extremely sensitive to initial conditions dependent, the initial conditions of the very small error will cause the results of a great difference.
we can use a widespread folk image of the butterfly effect to make clear that the first folk say:
lost a nail, a shoe bad;
broken a shoe, folded a horse;
folded a horse, hurt a knight;
hurt a knight, lost a battle;
lost a battle, death of an empire.
horseshoe on a nail is lost, this is a very small change, but its "long term" effect is an empire of survival and death. This is the "butterfly effect" in the military and political application.
is not it amazing? But the fact is the case, there are a number of seemingly insignificant things can cause very serious consequences, so things should be done in any preventive measure.
Interestingly, in a landmark paper published after Lorentz, the media is full on the "butterfly effect" a wide variety of reports, they seem to have simply declared that "weather is impossible." But Lorentz is not so simple, I thought he meant that weather can not be entirely accurate.
When the weather is rapidly changing, it did not accurately reflect the forecast, we naturally think of "Accidents will happen\Is there any scientific basis for these words? Weather is often not accurate enough, this is the calculation problem, or there is insufficient scientific

be?
Although the emergence of the twentieth century scientific theory of relativity and quantum mechanics, and other new theory, but Newton's mechanics in normal daily life, including weather, construction design, aircraft engineering, are still applicable. In recent years, as information technology, the rapid development of the basis of Newton mechanics to simulate the weather changes generally Chen Wei "numerical weather prediction" have become a mainstream weather forecasting.
order to make more accurate numerical weather prediction, scientists in two senses: in-depth study of the complex and delicate atmospheric changes, such as the internal structure of typhoons, thunderstorm formation processes disappear, the pursuit of excellence; the other hand strengthen the meteorological observation, such as increasing observation point, the development of satellite and radar technology to get more weather information.
In fact, because climate change is very complex, so the weather forecast, enter the initial conditions can not contain all of the influencing factors (usually simplified method is to ignore secondary factors of the principal factors), while those ignore secondary factors are likely to have a major impact on the forecast results, leading to wrong conclusions.
a result, Lorenz found that despite having high-speed computers and accurate measurement data (temperature, pressure, satellite Fengyun information, etc.), but also difficult to obtain accurate long-term weather forecasts.
Lorentz with superhuman perseverance will affect the weather of the 5 million variable compression to the three variables. Vision and style of the mathematician, tangible proof of a simple third-order nonlinear system will appear "chaotic" (Chaos), so convincingly that the weather system is chaotic.
