What is the butterfly effect?

The butterfly effect was put forward by meteorologist Lorenz in 1963.

The general idea is that a butterfly flapping its wings occasionally in the tropical rain forest in the Amazon basin of South America may cause a tornado in Texas in two weeks. The reason is that the movement of butterfly wings leads to the change of the air system around it and the generation of weak airflow, which in turn will cause the corresponding changes in the air around it or other systems, which will cause a chain reaction and 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.

The "butterfly effect" is used in sociology to explain that a bad tiny mechanism, if not guided and adjusted in time, will bring great harm to the society, which is called "tornado" or "storm"; A good tiny mechanism, as long as it is guided correctly, will have a sensational effect after a period of hard work, or be called "revolution".

What does the butterfly effect mean?

The butterfly effect is a metaphor, not a hurricane caused by butterflies. Hehe

What is the butterfly effect?

The butterfly effect theory is nonlinear, commonly known as the "butterfly effect".

what is the butterfly effect? Let's start with the discovery of Lorenz, a meteorologist at the Massachusetts Institute of Technology. In order to forecast the weather, he used a computer to solve 13 equations simulating the earth's atmosphere. In order to examine the results more carefully, he took out an intermediate solution, improved the accuracy and sent it back. And when he came back to see it after drinking a cup of coffee, he was surprised: there was a small difference, but the result was a hundred thousand miles away! There was nothing wrong with the computer, so Lorenz decided that he had discovered a new phenomenon: "extreme instability to the initial value", that is, "chaos", also known as "butterfly effect". The flapping of Asian butterflies will make a tornado worse than a strong wind appear in America in a few months!

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

linearity refers to the proportional and linear relationship between quantities, which represents regular and smooth motion in space and time; However, nonlinearity refers to the non-proportional and non-linear relationship, which represents irregular movement and mutation. For example: How many times is the visual acuity of two eyes more than that of one eye? It's easy to think of twice, but it's actually 6-1 times! This is nonlinearity: 1+1 is not equal to 2.

laser generation 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 "aligning to the right" and emit monochromatic light with the same phase and direction, that is, laser.

The characteristic of nonlinearity is that it cuts across all professions and permeates all fields, which can almost be said as "everywhere."

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

it can be seen that nonlinearity is around us and we can't hide it.

in December 1979, Lorenz pointed out in a speech at the American Association for the Advancement of Science in Washington that a butterfly flapping its wings in Brazil might 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, exciting 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, a very small change in initial conditions will make a great difference to its future state after constant amplification. We can use a folk song circulating in the west to illustrate this image. This ballad says:

Lost a nail and broke a shoe;

I broke a shoe and broke a war horse;

I broke a war horse and injured a knight;

wounded a knight and lost a battle;

lost a battle and lost an empire.

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

it's a little incredible, but it can really cause such bad consequences. A wise leader must guard against procrastination, but seemingly trivial things may cause disintegration within the collective. Isn't it too late to regret at that time?

A suspension bridge crossing a deep valley usually starts with a small stone tied to a thin thread. ...

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.

the extended meaning is that a small action at the beginning may cause great changes in the results.

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 in two weeks if it flaps its wings occasionally. The reason is that the movement of butterfly wings leads to the change of the air system around it and the generation of weak airflow, which in turn will cause the corresponding changes in the air around it or other systems, which will cause a chain reaction and eventually lead 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 the 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 196s. One day in the winter of 1961, E.Lorenz calculated the weather forecast on the Royal McBee computer. He has calculated a series of data of climate evolution under the setting of a certain initial value. 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 make the computer run from the beginning. He directly typed in the last intermediate data as the initial value of the calculation, and then calculated it according to the same procedure, hoping to get the same result as the second half of the last series. Then he went downstairs through the hall to have coffee. An hour later, when he came back, something unexpected happened. He found that the weather changed rapidly from the last result, and the similarity disappeared completely in a short time. The problem lies in the data he entered as the initial value this time. The computer originally stored a 16-digit decimal .56127… but he printed out a decimal .56 with only 3 digits, and he entered .56. Further calculation shows that the slight difference of input may soon become the huge difference of output, which is called the sensitive dependence of initial conditions and the' butterfly effect' in weather forecast. Lorenz's speech at the American Association for the Advancement of Science in Washington on December 29, 1979: "Predictability: Will a butterfly flap its wings in Brazil cause a tornado in Texas?"

second, the meaning of butterfly effect

a small butterfly flapping its wings over a certain place stirs up the air, which may lead to a storm in a distant place after a long time, which is a metaphor for the unpredictable and serious consequences caused by a little tiny factor in long-term large-scale weather forecast. Small deviations are inevitable, which makes the long-term weather forecast unpredictable or inaccurate. This is like playing billiards, playing chess and other human activities, which are often "a tiny miss, a thousand miles away" 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 only for weather forecast, but is synonymous with all complex systems that are extremely sensitive to initial values, which means that a slight change or deviation of initial values will lead to great differences in future prospects, which 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 a distant place after a long time. This is a metaphor that long-term large-scale weather forecast often has unpredictable and serious consequences because of a little tiny factor. Small deviation is inevitable, which makes long-term weather forecast unpredictable or inaccurate. This is like playing billiards, playing chess and other human activities, which are often "just a fraction of a mile". "a thousand miles away" and "one careless move will lose the game".

Long-term and large-scale weather forecast is to observe, calculate, analyze and judge the complex system of the earth's atmosphere, which is influenced and restricted by many factors such as temperature, humidity and pressure of the earth's atmosphere that change at any time and place. It can be thought that the prediction of its comprehensive effect is difficult to be accurate, and the butterfly effect is inevitable. The objects of our human research also involve other complex systems (including "natural system" and "social system"), and there are many complicated internal factors, so its "corresponding butterfly effect" is inevitable.

"Today's butterfly effect" or "generalized butterfly effect" is not limited to the original Lorentz. It is a synonym or synonym for all complex systems that are extremely sensitive to initial values, which means that for all complex systems, under certain "threshold conditions", their long-term and large-scale future behavior is extremely sensitive to small changes or deviations in the initial conditions, that is, a slight change or deviation in the initial values will lead to great differences in the future prospects, which is often unpredictable or random.

the butterfly effect means that a very small change in the initial conditions will make a great difference to its future state after constant amplification. Some small things can be confused, and some small things, if amplified by the system, are very important to an organization and a country, so we can't be confused.

what exactly does the movie butterfly effect mean?

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

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

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

butterfly effect means. Explain it in plain words. 5 points

That is to say, a little detail and a little factor will trigger a series of major changes

What does the butterfly effect mean?

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

Before watching a movie, you will read the story introduction first, otherwise it will be a waste of time and turn your stomach if you see something you don't like. However, don't forget that most of the plots are reproduced from each other, and sometimes they are really different from what you see.

Original life: It all started with that damn painting. A 7-year-old child actually drew a bloody painting of stabbing people with a knife, and later said that he didn't remember why he drew this painting. Can this make all concerned mothers and teachers suspicious? So, after some inspection, a new habit began to be cultivated-keeping a diary and recording everything that happened. However, afterwards, he was holding a knife as in the painting. The next second, the knife thumped to the ground, and once again he suffered from transient amnesia ... Then his worried mother gave little Evan to her neighbor's care, and the tragedy officially began ... < P > The neighbor (Tommy and Kayleigh's dad) took out his camera ... amnesia ... met his father ... amnesia ... Six years later, Tommy instigated ……Lenny to play a prank and the bomb exploded. So, Tommy trapped Evan's dog and tried to burn it, giving him a warning. Lenny couldn't untie the dog's pocket and was threatened by Tommy again ... amnesia ... The dog was burned to death (how do you think of the crazy brother who loves to burn dogs in the bee trap? Since we talk about the bee trap, we might as well talk a little more. My brother is crazy because maggots eat the brain marrow of children and multiply in his brain until his brother sees it. It's disgusting and shocking. After moving "I'll e back for you" ...

7 years later. In the past seven years, Evan has been all right, has no amnesia, and has gone to college to study psychology. The nightmare seems to have left him. Suddenly I read my diary again, but I returned to the scene of burning the dog. That lost memory … was actually found? ! Is it true?/You don't say. Evan asked Lenny for confirmation, only to find that Lenny had been immersed in childhood. What made him like this? Rereading the diary, the memory of the bomb was retrieved. It turned out that the bomb killed a woman (Mrs. Hepburn) and her child, all because Tommy prevented Lenny from making amends ... < P > Evan met his mother, and her mother told Evan that his father was his age and said that he could recall some forgotten things ... On a whim, her mother took Evan to fortune telling. The psychic's words made his mother tell Evan one thing: before Evan was born, she was pregnant twice, but both of them were stillborn (note that this is an extremely important foreshadowing)

Evan wanted to recall what his neighbor did with the camera, but he was blocked by his roommate's friends (if he listened to his roommate and didn't pursue it again, it might not happen). He went back to find Kayleigh, but inadvertently uncovered Kayleigh. Evan decided to go back to the past and make a change ...

The first change: in front of the camera, the neighbor wanted Evan and Kayleigh to film children * * *, and little Evan scolded the old goat and asked him to take care of his son and not touch Ka.
