Knowledge is in line with the direction of civilization, and it is the sum total of human exploration achievements in the material world and the spiritual world. So far, there is no unified and clear definition of knowledge. But the criterion for judging the value of knowledge lies in practicality, considering whether human beings can create new substances and gain strength and motivation.

Knowledge is an understanding of a subject, which has the potential to be used for a specific purpose. It means to get familiar with something through experience or association; This fact or state is called knowledge, which includes knowing or understanding a certain science, art or skill.

In addition, it also refers to a set of knowledge or a series of information obtained through research, investigation, observation or experience. The ability to know things is one of the controversial central topics in philosophy, which has its own branch-epistemology. On a more practical level, knowledge is usually enjoyed by some people. In this case, knowledge can be operated and managed in different ways.

Extended data:

Situational knowledge is knowledge about specific situations. Imagine two very similar mushrooms, which grow on different sides of the mountain. One is nutritious and the other is poisonous. The knowledge of edible fungi obtained on this side of the mountain does not apply to the use on the other side of the mountain.

Knowledge produced by trial and error or learned through experience is often situational knowledge. The knowledge produced by scientific method is more objective than that produced by other methods, which is also one of the advantages of scientific method.

Situational knowledge is usually embedded in language, culture or tradition. There is a view that criticizes cultural imperialism and holds that the rise of global monoculture has led to the disappearance of local knowledge.
