Give me an example to explain the butterfly effect, thank you!

From the perspective of the "butterfly effect", Wu Song's personal behavior may have affected the Song Dynasty and even world history.

This is just like in butterfly effect economics, the economy and society do not operate like machines, but more like living organisms.

In November 1059 AD, Wu Erlang, who killed a tiger on Jingyang Gang, was promoted exceptionally.

Wu Dutou was playing on the street and met his long-lost brother Wu Dalang.

Pan Jinlian, a sister-in-law, has a crush on her eight-foot-tall brother-in-law who has the status of a "cadre".

A few days later, when Wu Dalang went out to sell sesame cakes, a temptation spread at home, but he failed. Wu Dutou, a righteous man, sternly rejected him and moved back to the county government to show his determination.

Next, Pan Jinlian hooked up with Ximen Qing and poisoned Wu Dalang.

In Wudu, blood spattered Yuanyang Tower and Jiang Menshen was drunk.

Then he walked to Centipede Ridge at night and met Song Gongming in Time, and decided to rebel together.

If Wu Song followed Pan Jinlian, what would the history of the Song Dynasty be like?

Let us spread the wings of our imagination: First of all, it is difficult for Song Jiang to be recruited without Wu Song; Liangshan heroes would not conquer Fangla, and even if they conquered, there would be no one-armed Wu Song to capture Fangla.

If Fang La had not died, the Song Dynasty might not have attacked the Liao Dynasty, the Jin Dynasty would not have risen, Mongolia would not have destroyed the Jin Dynasty, and the Song Dynasty would not have perished... The moment Wu Song pushed Pan Jinlian away, he opened Pandora's box.

Tear down the dominoes that rewrote the history of the Song Dynasty!

However, the discovery of the chaos effect in 1963 posed a huge challenge to traditional economics: scientist Lorenz published an article in the magazine "Atmospheric Science" and pointed out that there must be a gap between the inability of climate to accurately reproduce and the inability of long-term weather forecasters.

This is the connection between non-cyclicality and unpredictability.

He also discovered the "extreme sensitivity of chaos to initial conditions."

This can be vividly compared to the "butterfly effect": in theory, if a butterfly in Brazil flaps its wings, this disturbance will cause a very large difference in another place far away, which will make long-term predictions

It was impossible to carry out, and was even amplified by the system into a storm thousands of kilometers away in Africa.

Extended information: The "butterfly effect" on the tip of the Chinese tongue: British media said that the Chinese middle class is keen to buy American pork, causing residents next to the pig farm in North Carolina to complain because the increase in pigs has brought about the smell of pig manure.

question.

It is also reported by the British media: China has significantly reduced its milk imports, creating a global milk surplus and international milk prices falling to a six-year low.

If you browse casually, there are countless such news: such as "Chinese demand pushes up the price of fruit in Japan", "Chinese demand pushes up the price of Malaysian bird's nest".

The "storm" caused by the tip of the tongue is just the tip of the iceberg.

Gold prices tumbled as the Chinese market unexpectedly sold tons of gold bars.

Some American media complained bitterly: "The slowdown in China's demand has made the U.S. coal industry even worse." In a word, China's demand has as much power as the "butterfly effect" in the global market.
