What is the butterfly effect?

The butterfly effect was put forward by meteorologist Lorenz 1963.

A butterfly flapping its wings occasionally in the tropical rain forest of Amazon basin in South America may cause a tornado in Texas within two weeks. The reason is that the movement of butterfly wings leads to the change of the surrounding air system, producing weak airflow, which in turn will cause the corresponding change of the surrounding air or other systems, causing a chain reaction, which will eventually lead to great changes in other systems.

This effect shows that the result of the development of things is extremely sensitive to the initial conditions, and the smallest deviation of the initial conditions will cause great differences in the results.

Sociology uses "butterfly effect" to explain a bad tiny mechanism, which will bring great harm to society if it is not guided and adjusted in time, nicknamed "tornado" or "storm"; A good micro-mechanism, as long as it is guided correctly, will have a sensational effect after a period of efforts, or it will be called a "revolution."

Butterfly effect is a metaphor, not a hurricane caused by butterflies, hehe.

What is the butterfly effect theory?

Nonlinear, commonly known as "butterfly effect".

What is the butterfly effect? Let's talk about the discovery of Lorenz, a meteorologist at MIT. In order to forecast the weather, he solved the 13 equation simulating the earth's atmosphere by computer. In order to check the results more carefully, he took out an intermediate solution, improved the accuracy and sent it back. And when he came back to watch it after drinking a cup of coffee, he was surprised: it was a little short, but the result was a hundred thousand miles short! There was nothing wrong with the computer, so Lorenz decided that he had discovered a new phenomenon: "extreme instability to the initial value", namely "chaos", also known as "butterfly effect". The flapping of Asian butterflies will make a tornado worse than strong winds appear in the United States in a few months!

This discovery is so serious that scientists don't understand it, and several scientific journals also refuse to publish his articles, thinking that it is "against common sense": if similar initial values are substituted into some equations, the results should be similar, how can they be far apart!

Linearity refers to the proportion and linear relationship between quantity and quantity, representing regular smooth motion in space and time; Nonlinear refers to the non-proportional and nonlinear relationship, which is characterized by irregular movement and mutation. For example, how many times is the eyesight of two eyes more than that of one eye? It's easy to think it's twice, but it's actually 6- 10! This is nonlinearity: 1+ 1 is not equal to 2.

The generation of laser is nonlinear! When the applied voltage is small, the laser is like an ordinary electric lamp, and the light scatters in all directions; When the applied voltage reaches a certain value, a new phenomenon will suddenly appear: the excited atoms seem to hear the command of "align to the right" and emit monochromatic light in the same phase and direction, that is, laser.

The characteristic of nonlinearity is that it spans all professions and permeates all fields, which can be said to be "everywhere".

For example, there is chaos in celestial motion; The oscillation of electricity, light and sound waves will suddenly fall into chaos; The geomagnetic field changed direction 16 times in 4 million years, also because of chaos. Even human beings are inherently nonlinear: contrary to traditional ideas, the EEG and heartbeat of healthy people are not regular, but chaotic, and chaos is the expression of vitality. Chaotic systems react faster to the outside world than non-chaotic systems.

It can be seen that nonlinearity is around us and can't be hidden.

1979 12, Lorenz pointed out in a speech of the American Association for the Advancement of Science in Washington that a butterfly flapping its wings in Brazil may cause a tornado in Texas. His speech and conclusion left a deep impression on people. Since then, the so-called "butterfly effect" has spread like wildfire, and its reputation has spread far and wide.

The reason why the butterfly effect is fascinating, gripping and thought-provoking lies not only in its bold imagination and charming aesthetic color, but also in its profound scientific connotation and inherent philosophical charm.

Chaos theory holds that in a chaotic system, very small changes in initial conditions, after constant amplification, will cause great differences in its future state. We can use a folk song circulating in the west to illustrate this image. This ballad says:

Drop a nail and break a shoe;

Broke a shoe and a horse;

Fold a horse and hurt a knight;

Wounded a knight and lost a battle;

Lost a battle and lost an empire.

Whether a nail on the horseshoe will be lost is a very small change in the initial conditions, but its "long-term" effect is the fundamental difference between the life and death of an empire. This is the so-called "butterfly effect" in the field of military politics.

It's a little incredible, but it can really cause such bad consequences. A wise leader must prevent procrastination, but seemingly trivial things may lead to disintegration within the collective. Is it too late to regret at that time?

A suspension bridge across a deep valley usually begins with a small stone tied to a thin line. ...

What does the butterfly effect mean?

The source of this word is that a typhoon in the Pacific Ocean may have originated from a butterfly flapping its wings.

By extension, it means that a small action at the beginning may cause a big change in the result.

What does the butterfly effect mean?

The "butterfly effect" says that a butterfly in the tropical rain forest near the Amazon River in South America may cause a tornado in Texas within two weeks if it flaps its wings occasionally. The reason is that the movement of butterfly wings leads to the change of the surrounding air system, producing weak airflow, which in turn will cause the corresponding change of the surrounding air or other systems, causing a chain reaction, and finally leading to great changes in other systems. The "butterfly effect" sounds absurd, but it shows that the result of the development of things is extremely sensitive to initial conditions; The smallest deviation of initial conditions will cause great differences in results.

First, the origin of the butterfly effect

The butterfly effect originated from the discovery of American meteorologist Lorenz in the 1960s. 196 1 one day in winter, E.Lorenz calculated the weather forecast on the royal McBee computer. He calculated a series of data of climate evolution under certain initial values. When he turned on the computer again to investigate this series of longer-term evolution, in order to save trouble, he took a shortcut and did not let the computer run at the beginning. He directly typed in the last intermediate data as the initial value of calculation, and then calculated according to the same procedure, hoping to get the same result as the second half of the last series. Then he went downstairs and crossed the hall to have coffee. An hour later, when he came back, something unexpected happened. He found that the weather changed quickly from the last result, and the similarity disappeared completely in a short time. The problem is that the data he entered this time is used as the initial value. The computer originally stored 16 decimal 0.506 127…, but he printed out a decimal 0.506 with only three digits, and he entered 0.506. Further calculation shows that a small difference in input may soon become a huge difference in output, which is the so-called sensitive dependence of initial conditions and the' butterfly effect' in weather forecast. Lorenz 1979 12/29 Speech at the American Association for the Advancement of Science in Washington: "Predictability: Will a butterfly flap its wings in Brazil cause a tornado in Texas?"

Second, the meaning of the butterfly effect

A small butterfly flapping its wings over a certain place and stirring the air may cause a storm in a distant place for a long time, which is a metaphor for the unpredictable and serious consequences caused by a small factor in long-term large-scale weather forecast. Small deviations are inevitable, which makes long-term weather forecast unpredictable or inaccurate. This is like playing billiards, chess and other human activities, which are often "a thousand miles away, a tiny difference" and "one careless move will lose the game." "Today's butterfly effect" or "generalized butterfly effect" is not limited to the original Lorenz butterfly effect, which is only used for weather forecasting, but is synonymous with all complex systems that are extremely sensitive to initial values, which means that small changes or deviations in initial values will lead to great differences in future prospects, and this difference is often unpredictable or random.

A small butterfly flapping its wings over a certain place disturbs the air, which may lead to a storm in the distance for a long time. This is a metaphor. Long-term large-scale weather forecast often leads to unpredictable and serious consequences because of a little tiny factor. Small deviations are inevitable, which makes long-term weather forecast unpredictable or inaccurate. This is like playing billiards, chess and other human activities, which are often "thousands of miles away" and "one careless move, one careless move"

Long-term large-scale weather forecast is the observation, calculation, analysis and judgment of the complex system of the earth's atmosphere, which is influenced and restricted by many factors that change at any time and place. It can be considered that the prediction of its comprehensive effect is difficult to be accurate and the butterfly effect is inevitable. Our human research objects also involve other complex systems (including "natural systems" and "social systems"), and their internal constraints are also complex, and their "butterfly effect" is inevitable.

"Today's butterfly effect" or "generalized butterfly effect" is not limited to the original Lorenz butterfly effect, which is only used for weather forecasting, but is synonymous with all complex systems being extremely sensitive to initial values, which means that for all complex systems, under certain "threshold conditions", their long-term and large-scale future behaviors are extremely sensitive to small changes or deviations of initial conditions, that is, small changes or deviations of initial values will lead to huge future prospects.

What does the butterfly effect mean?

Butterfly effect refers to a very small change in initial conditions, which will have a great impact on its future state after continuous amplification. Some small things can be confused, and some small things are very important to an organization and a country if they are amplified by the system, so we can't confuse them.

What exactly does the movie butterfly effect mean?

In fact, the theme of the film is this: any decision made at an early age may change the life of yourself or others.

First of all, the condition that a hero can cross is that he can recall the situation at that time. So watching that movie is to take him back to the party at that time, and it was at that party that he met the heroine. In the previous situation, no matter how he chooses, he will put the heroine or himself in a very bad position (for example, she has no hands or feet and is with fatty Lanny). Finally, after these endings, he realized that these endings were caused after he met her at that party, so he decided to go back to the party and make a bad impression on his own initiative. Naturally, they will not know each other, and those tragedies will not happen.

So there is an ending. I hope I can analyze it clearly and you can understand it.

What does the butterfly effect mean? Explain it in plain words. 5 points

In other words, a small detail, a small factor, will trigger a series of major changes.

What does the butterfly effect mean?

Butterfly effect: life goes round and round, changing an ending five times.

I will read stories before watching movies, or I will waste my time and turn my stomach if I don't like them. However, don't forget that most of the plots are reproduced from each other, and sometimes they are really different from what you see.

Native: It all started with that damn painting. A 7-year-old child actually drew such a bloody picture of stabbing people with a knife, and later said that he couldn't remember why he drew this picture. Can this make mothers and teachers who care about their children suspicious? So, after some inspection, a new habit began to develop-keeping a diary and recording everything that happened. However, after that, he actually held a knife as in the picture. The next second, the knife fell to the ground with a bang, and he suffered from transient amnesia again ... Then the uneasy mother gave little Evan to her neighbor to take care of, and the tragedy officially began. ...

Neighbors (Tommy and Kelly's father) took out their cameras ... Memory loss ... met their father ... Memory loss ... Six years later, Tommy instructed Lenny to play a prank, the bomb exploded ... Memory loss ... Lenny was locked up, and Evan kissed Kelly for the first time in the cinema, which caused resentment from Kelly's brother Tommy. So Tommy trapped Evan's dog and tried to burn it to give him a warning. Lenny can't untie the dog's pocket, and he is threatened by Tommy ... Memory is missing ... The dog is burned to death (what do you think of the crazy brother who loves to burn dogs in the bee trap? Now that we are talking about bee traps, we might as well say a little more. My brother is crazy because maggots eat the brain of the child and breed in his brain until his brother sees it. It's disgusting and shocking. He said, "I'll come back for you." ...

Seven years later. In the past seven years, Evan has been fine, has no memory loss, and went to college to study psychology. The nightmare seems to have left him. Suddenly I read the diary again, but I returned to the scene of burning dogs. Lost memory ... really found it? ! Is it true?/You don't say. /You don't say. Evan asks Lenny for proof, only to find that Lenny has been immersed in his childhood. What made him like this? Rereading the diary, I found the memory of the bomb. It turned out that the bomb killed a woman (Mrs Hepburn) and her child, all because Tommy prevented Lenny from making compensation. ...

Evan got together with his mother, who told Evan that his father could recall some forgotten things at his age ... His mother took Evan to fortune-telling on a whim. The psychic's words made her tell Evan one thing: Before Evan was born, she was pregnant twice, but both were stillbirths (note that this is an important foreshadowing).

Evan wants to recall what his neighbor did with the camera, but his roommate stopped him (if he listened to his roommate and let it go, there might not be any more). He went back to Kelly, but inadvertently uncovered Kelly's scar, which led to Kelly's suicide. Only then did he find himself deeply in love with Kelly. Evan decided to go back and make some changes. ...

The first change: In front of the camera, the neighbors want Evan and Kelly to film the children. Little Evan scolded the old goat and told him to take care of his son and not touch Kelly. Back now, Evan and Kelly have become a couple, which is a good thing, but Tommy, who is haunted by ghosts, is haunting them again. It turned out that Evan's words caused neighbors to fight with their sons and treat their daughters as babies, which made Tommy hate Evan even more. New hatred and old hatred came to mind together, and Evan accidentally killed Tommy. After only a short happy day, Evan fell from heaven to hell-prison. Prison life is not easy (see The Shawshank Redemption and Prison Break, where all the men have strange hobbies like homosexuality). In order to save himself, Evan began a second change (the diary was taken to prison by his mother, which made up for the memory of painting, which was a loophole in the script, and obviously he started writing a diary after painting) ...

The second change: Before going to save the dog, little Evan gave Lenny a sharp weapon so that he could untie his pocket. Then Evan and Tommy confronted PK, Tommy released the dog voluntarily, and then ... Lenny's sharp weapon got stuck in T. ......

What is the butterfly effect? What is Murphy's Law?

Butterfly effect refers to a chaotic phenomenon that small changes in initial conditions can drive the long-term huge chain reaction of the whole system. The "butterfly effect" often appears in chaos.

Butterfly effect is usually used in weather, stock market and other complex systems that are difficult to predict in a certain period of time. If this gap is getting bigger and bigger, it will be very destructive. Why the weather or the stock market will have unpredictable natural disasters and crashes.

The application of butterfly effect in psychology: the butterfly effect refers to a seemingly insignificant and very small thing, but it may bring about great changes. This effect shows that the result of the development of things is extremely sensitive to the initial conditions, and the smallest deviation of the initial conditions will cause great differences in the results.

The specific content of Murphy's theorem is that "everything that can go wrong will go wrong", that is to say, as long as the probability of any event is greater than zero, it cannot be assumed that it will not happen.

Main contents:

First, nothing is as simple as it seems;

Second, everything will take longer than you expected;

Third, things that can go wrong will always go wrong;

If you are worried about something happening, it is more likely to happen.
