A detailed explanation of Murphy's law? (full version)

1949, an air force captain engineer named Murphy thought one of his colleagues was unlucky and made a casual joke:' If something is likely to be screwed up, let him do it, and things will be screwed up.'

This sentence spread quickly and spread all over the world. In the process of communication, this joke gradually lost its original limitations and evolved into various forms. The most popular form is: "If a bad thing is possible, no matter how likely it is, it will always happen and cause the greatest possible loss." This is the famous Murphy's Law.

The following are some variations or inferences of Murphy's law.

Don't quarrel with fools, or others will be confused. Who is a fool?

Don't feel important, because without you, the sun will still rise in the east tomorrow.

Smile, tomorrow is not necessarily better than today.

It depends on whether you are squatting in the toilet or waiting outside.

The western "Murphy's Law" says: Anything that may go wrong will go wrong. "Anything that can go wrong is bound to go wrong."

The original words of Murphy's law are as follows: if there are two or more ways to do something, and one of them will lead to disaster, then someone will do it. If there are two choices, one of which will lead to disaster, someone will definitely make this choice. According to Murphy's law, first of all, 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; Fourth, if you are worried about something happening, it is more likely to happen.

Do you know who discovered this law? Can you believe that it was not created by philosophers, priests, writers or scientists, but by an engineer's improvisation?

Edward a Murphy is an engineer. He participated in 1949 MX98 1 experiment conducted by the United States Air Force. The purpose of this experiment is to determine the tolerance limit of human beings to acceleration. One of the experimental projects is to hang the 16 rocket accelerometer above the subject. At that time, there were two ways to fix the accelerometer on the bracket, but incredibly, someone methodically installed all the 16 accelerometers in the wrong position. So Murphy made this famous assertion, which was quoted by the subject at the press conference a few days later. A few months later, this "Murphy's Law" was widely used in aerospace machinery related fields. After many years, this "law" has gradually entered the category of idioms, and its connotation has been endowed with infinite creativity, and many variants have appeared, among which the most famous one is also called Finagle law, and its specific content is: if anything can go wrong, it will go wrong. You will make mistakes in the end. )。 This law is considered to be the best imitation and elaboration of Murphy's law.

After reading the above story, you may ask, what is the significance of this law to our real life? In fact, "Murphy's Law" is just a concept, which has different meanings for different people and under different circumstances. For example, for computer users, the implication of this law is that anything that can go wrong will go wrong. Therefore, computers are not gods and omnipotent. Even the best computers sometimes have problems and bring trouble. So important information must be backed up, just in case.

Another example is:

Stock trading, you are afraid of falling, it just falls on your head; You expect to go up, but you can't go up; You can't help selling it, it has already started to rise; You watch five stocks and buy one of them. As a result, except for this one in your hand, all the other four stocks rose very well.

When buying lottery tickets, the easiest number to win is the number you chose but didn't bet on. The lottery ticket you lost is the one you won. If you win the lottery and don't lose it, the winner must be the smallest prize.

In the queue, the other row always moves faster. You moved to another row, the row where you were standing, and you started to speed up. The longer you stand, the more likely you are to stand in the wrong row.

If you don't take a taxi, there will be lanterns all over the street. If you are in a hurry and don't have an empty car for a long time, you will definitely refuse to carry it.

If many people are waiting at the bus stop, they are waiting for the same bus as you. The tighter your time is, the less the bus will come. Here comes the bus. It's definitely not what you want to take. If you can't wait, you can call a taxi. As soon as you leave, your bus will come.

There are two attitudes towards Murphy's law: the weak regard it as an excuse for helplessness, and the strong regard it as an alarm to remind themselves to be vigilant at any time.

It should be noted that Murphy's law, which seems absurd but incisive, is not an idealistic theory, but a serious philosophical proposition. They cover every corner of life, life, love, work and study. It has its positive significance. Just think of everything from the worst, don't take chances, try your best, so that when you get it, you will be surprised.

This is actually that probability is at work, and people are not as good as the sky. As the old saying goes, "Nothing is difficult in the world, and nothing is impossible to a willing mind." And "it never rains but it pours". For example, if you don't win the lottery in several issues, you will definitely win the million-dollar prize in the end. Although the probability of disaster is very small, it will break out from the weakest link when it accumulates to a certain extent. Therefore, the key is to clean up the dead angle at ordinary times, eliminate unsafe hidden dangers and reduce the accident probability.

In the face of God's unfathomable and human's own defects, we'd better consider it more carefully and comprehensively, and take various insurance measures to prevent accidents and losses caused by human error. We should feel some kind of goodwill hidden behind Murphy's law and understand its positive significance through its exaggerated expression.

Come whatever you are afraid of, and the good state is: just think about the technical essentials and forget yourself.

murphy's theorem

1. Nothing is as simple as it looks.

Second, everything will take longer than you expected.

Third, things that may go wrong will always go wrong.

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

Murphy, a test engineer at Edward Air Force Base in the United States, invented a famous theorem. People named this theorem after the master of pessimism, and this theorem, which is widely known in engineering construction and enterprise management, is called Murphy theorem. Murphy's theorem is expressed as follows:

If a thing is likely to develop in a bad direction, it will certainly develop in the worst direction.

For example, a toolbox is not taken away in time after work, but left at a certain height. According to Murphy's theorem, the toolbox is bound to fall from a height, and the toolbox will not only break into pieces on the ground. According to Murphy's theorem, the toolbox should fall on someone's head. Of course, the victim will not be a casual person. Murphy's theorem points out that the victims will be politicians who come to inspect. Followed by the difficult widow of the deceased, capable lawyers, angry colleagues and mean journalists. Finally, due to an amendment to the law made by people thousands of miles away in the capital a week ago, the people concerned have to face charges from second-degree murder while paying huge compensation.

Murphy's theorem was later extended to fields other than engineering construction and enterprise management. Because people find that Murphy's theorem is also applicable elsewhere.

Occasionally, people are lucky not to use condoms. Murphy's theorem will give him a positive test report. The test report does not mean that the subject is pregnant, because the subject is male and the report is not issued by a gynecologist. In addition, Murphy's theorem favors other possibilities. The National Center for Disease Control and Prevention sadly announced that the tested person was confirmed as an HIV carrier. It's not over. This person's wife and their respective friends will also be confirmed to be infected with HIV. But sometimes Murphy's theorem can do nothing, and the unpleasant scene that should have appeared did not appear, because no one cares about adultery exposed in broad daylight anymore.

The reason why I want to talk about Murphy's theorem in hot spots is because I found that Murphy's theorem is also an irrefutable truth in China.
