Why does a Brazilian butterfly flapping its wings trigger a hurricane in the United States?

The main reason is that the power of this butterfly effect is very great, and a small fan can cause a lot of wind.

Because the United States is more prone to hurricanes, and then the Brazilian butterflies will vibrate when they flap their wings.

Because this is the butterfly effect, there is a certain causal and inevitable connection.

I think because of their geographical location, nature works differently.

No, it should be a metaphor, if it is really possible, the wind brought by the walking, the effect of talking and sneezing will not destroy the earth.

The discipline of chaos arose in the sixties and seventies of the last century and is still popular today. In 1987, American writer Greg wrote a best-selling book, Chaos: Creating a New Science, which won the Pulitzer Prize.

The first chapter of the book is called the Butterfly Effect. The so-called "butterfly effect" is an important feature of chaos theory. It is believed that a butterfly in Brazil could flapp its wings, causing a hurricane in Texas.

The name "butterfly effect" is now considered the result of a misunderstanding. It was proposed by Lawrence, an early researcher of chaos theory, and American meteorologists. Lawrence himself never used the term in ** or in research reports.

He used to use the analogy of a seagull. The appearance of "butterflies" was a small thing that he attended at the conference in 1972. In this case, he did not provide the title of the report in time, and the chairman of the meeting drafted a paper "Will the wings of Brazilian butterflies cause hurricanes in Texas?"

Lorenz's findings were that there was a curve that looked like a butterfly pattern with an outstretched wing. Since then, the little butterfly has become the "image" of chaos theory.

Is there really a butterfly flapping its wings in the world? Is it possible to cause a hurricane thousands of miles away? According to chaos theory, the answer is yes.

In fact, it's just a phenomenon that has been in the spotlight for a long time: subtle factors can sometimes have a huge impact. This phenomenon is reflected in some part in idioms such as "different errors, false errors, and wholes", but in the past, no one has elevated it to the theoretical level or built its theoretical model.

Since the end of the 19th century, scientists have noticed that in some nonlinear complex systems, the state of the system depends on the initial conditions, and the phenomenon is extremely sensitive to the evolution of time.

That is, if there is a small change in the initial conditions (the wings of the butterfly's wings), it can also evolve into a very large difference (hurricane) after a period of time. This phenomenon is known as the "butterfly effect".

This is known as the butterfly wing effect!
