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.
1. The meaning of the effect
In the tropical rain forest of the Amazon River basin in South America, a butterfly flapping its wings casually can trigger a catastrophic storm 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. Scientists call this phenomenon "butterfly effect", which means that a seemingly unrelated and very small thing 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.
2. A brief description of the effect
Edward lorenz, an American meteorologist, analyzed this influence in the paper 1963 submitted to the New York Academy of Sciences. "A weather?
Scientists mentioned that if this theory is proved to be correct, a seagull flapping its wings is enough to change the weather forever. In his later speeches and papers, he used more poetic butterflies. The most common explanation for this effect is: "A butterfly flapping its wings in Brazil can trigger a tornado in Texas a month later."
The source of this sentence is that meteorologists have made a computer program that can simulate climate change and display it with images. Finally, he found that the image was chaotic, much like the spread wings of a butterfly. So he explained this figure vividly in the way of "butterflies flapping their wings", so there was the above statement.
Butterfly effect is usually used in weather, stock market and other complex systems that are difficult to predict in a certain period of time. 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.
Butterfly effect is used in sociology to explain a bad micro-mechanism, which will bring great harm to society if it is not guided and adjusted in time, and is dubbed as "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."
The butterfly effect often appears in chaos. Also known as nonlinear.
3. The source of the effect
The Origin of Butterfly Effect
Lorenz curve-knowledge
The concept of "butterfly effect" was put forward by meteorologist Lorenz 1963. In order to forecast the weather, he used a computer to solve the 13 equations that simulated the earth's atmosphere, in order to improve the accuracy of long-term weather forecast by using the high-speed operation of the computer.
Its origin is as follows: in an experiment in 1963, Lorenz, a meteorologist at MIT, solved the 13 equation simulating the earth's atmosphere with a computer. In order to check the results more carefully, Lorenz rounded off the fourth decimal place of the initial input data in a scientific calculation. He took out an intermediate solution of 0.506, improved the accuracy to 0.506 127 and sent it back. He drank a cup of coffee, and when he came back, he was surprised: there was not much difference, but the calculation results before and after deviated from 108 thousand miles! Results the similarity between the two curves disappeared completely. After checking again, I found that there was nothing wrong with the computer. Lorenz found that because the error will increase exponentially, in this case, a small error has caused great consequences as it goes on. Later, Lorenz raised this question in a speech. He believes that in the process of atmospheric movement, even if all kinds of errors and uncertainties are small, it is possible to accumulate the results in the process and gradually enlarge them to form a huge atmospheric movement.
So Lorenz decided that he had discovered a new phenomenon: the result of the development of things was extremely sensitive to the initial conditions. He later identified this as "extreme instability to the initial value", namely "chaos", also known as "butterfly effect". Since then, the so-called "butterfly effect" has spread like wildfire.
4. Effect charm
The butterfly effect has infinite charm.
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.
An important feature of chaotic system is "a tiny difference, a thousand miles away". Butterfly effect is an example of chaos theory. 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 illustrate this point with a folk song circulating in the west. 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.
5. Example of effect
An example of the butterfly effect
The Asian financial crisis of 65438-0998 and the American stock market storm are actually "butterfly effects" in economic operation; The "El Nino" phenomenon in the Pacific Ocean from 65438 to 0998 is the "butterfly effect" caused by atmospheric movement. The "butterfly effect" is the expression of chaotic motion. When we further study life phenomena, they are neither completely periodic nor completely random. They are all "frequency-locked" to natural periodic processes (season, day and night, etc.). ) and maintain the inherent "autonomous" nature.
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 also a concept in chaos theory. It refers to a dependence on the sensitivity of initial conditions: the small difference at the input end will be quickly amplified to the overwhelming difference at the output end, just like a butterfly flapping its wings in Beijing today, which may trigger a series of events in the atmosphere, thus leading to a storm in new york in a month.
6. And chaos
Butterfly effect and chaos theory
Butterfly effect is a concept in chaos theory. It refers to a dependence on the sensitivity of initial conditions: small differences at the input end will be quickly amplified to the output end, and the butterfly effect can be seen everywhere in economic life.
Butterfly effect, also known as billiards effect, is a figurative term that chaotic systems are extremely sensitive to initial values, and it is also the direct cause of chaotic phenomena in nonlinear systems under certain conditions (which can be called critical conditions or threshold conditions).
7. Affect life
The butterfly effect affects life.
What factors affect our future? Does everyone have a "butterfly effect" in life?
People always feel that in their own lives, it is not a specific event that ultimately affects their lives. The fact is, what is the general trend of all your decisions in this countless incident? In other words, how positive was your decision? Or more decadent? It doesn't matter which decision you make, what matters is the direction in which you make all decisions, big or small. This is what the so-called "opportunity favors those who are prepared" means, because those who are prepared make most of their life decisions in a positive direction.
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."
At first, the butterfly effect is chaotic, which is produced by imprecision or precision, so anything can happen. As a result, because accident also produces necessity, there is accident in necessity, and that's the way it is.
Chaos is nonlinear. Linearity refers to the proportion and linear relationship between quantity and quantity, representing regular smooth motion in space and time; Non-linearity refers to the relationship between proportion and linearity, which represents irregular movement and mutation. For example, how many times is the eyesight of two eyes more than that of one eye? It is easy to think that it is twice, but it is actually 6~ 10 times! 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 light source seems to hear the command of "align to the right" and emit uniform monochromatic light, that is, laser.
For example, there is chaos in celestial motion; The oscillation of electricity, light and sound waves will suddenly appear 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 thinking, the EEG and heartbeat of healthy people are not regular, but chaotic, and chaos is the expression of vitality. Chaotic systems respond faster to external stimuli than non-chaotic systems. It can be seen that nonlinearity is around us and can't be hidden.
The butterfly effect, a complex chain effect, may happen to us every day. We can't go back to the past to change our past and change our future. What we need is to correctly grasp our present. Perhaps, the future results will be better. You may not find the wrong step for a short time, but what may be destroyed in a few decades is not your future, but more.
It is no exaggeration that a trivial action may change a person's life. Examples that can be used as evidence are easy to find. Ford Company of the United States is famous in the world, which not only makes the American automobile industry in the forefront of the world, but also changes the national economic situation of the whole United States. Who would have thought that Ford, the creator of this miracle, was actually just a simple action of "picking up waste paper" when he entered the company.
At that time, Ford had just graduated from college, and he applied for a job in a car company. Several people who applied together have higher academic qualifications than him. Ford felt hopeless when others interviewed him. When he knocked at the door and walked into the chairman's office, he found a piece of paper on the floor at the door. Naturally, he bent down and picked it up. Looking at it, it turned out to be a piece of waste paper and threw it into the garbage basket. The chairman sees all this in his eyes. Ford just said, "I'm here to apply for Ford." The chairman issued an invitation: "Very good, very good, Mr. Ford, you are hired by us." This decision that surprised Ford actually came from one of his casual actions. From then on, Ford began his brilliant road until he changed his name to the company and made Ford famous all over the world.
Ford's harvest seems accidental, but it is inevitable. Their subconscious actions come from a habit, and the formation of habits comes from their positive attitude, just like the famous psychologist and philosopher William? James said: "sow the next action and you will get a habit;" Sow a habit and you will gain a character; Sow a character and you will reap a fate. "
In fact, the "butterfly effect" used by scientists to vividly illustrate chaos theory also exists in our lives: a bold attempt, a bright smile, a habitual action, a positive attitude and a sincere service can all start from an unexpected starting point in life, which can bring far more than a little joy and superficial return.
Knowing the "butterfly effect", do we understand that people should live actively and start from every little thing?
