Murphy's law has two premises: first, the probability is greater than zero; The other is that the time is long enough (in other words, the sample is large enough).

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 definitely make this choice.

"Murphy's law" (English: Murphy's theorem) has four 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.

The fundamental content of Murphy's Law is that "everything that can go wrong has a high probability of going wrong", that is to say, as long as any event has a probability greater than zero, it cannot be assumed that it will not happen.

Murphy's law exists objectively. Some people regard it as an excuse to be powerless, while others regard it as a wake-up call to remind themselves to be vigilant at any time. In the face of hidden functional defects in software, if we can think more thoughtfully and comprehensively and take various preventive measures, we may be able to minimize the defect rate.

Murphy's law is not terrible. As long as we can understand it scientifically and treat it positively, we will be able to overcome the negative effects brought by Murphy's Law and always maintain a happy and successful attitude. The chance of success may be included in the risk. Learn how to deal with risks and keep learning from them, so that we can grasp success more easily.

Scientific explanation of Murphy's law

Every law can be explained by one or several simple mathematical or physical laws, and the scientific explanation behind Murphy's law is the phenomenon of entropy increase in the universe.

It is generally believed that our universe is currently expanding. In this state, things tend to be transformed into microscopic particles and thermal radiation that are scattered in space in disorder and evenly. This disorder is called entropy increase.

Usually, the purpose of human activities is to establish centralized and orderly things, such as smelting iron ore into steel components and sand into pieces, which is contrary to the natural laws of the whole universe. Therefore, whether it is the punishment of nature or the cost of violating objective laws and destroying the order of things, Murphy's law is the embodiment of the natural laws of the universe.
