Physics is different from other sciences. Constantly thinking, while separating the necessary from the unnecessary. If mathematics is an exact science and we always get the right result. In physics, it is necessary to choose important factors from the set, and not important ones, to determine the influence of one factors on others, their interaction. It is important for physics to understand how it works and how it works. With the help of physics, people seek to understand various phenomena in nature and in society, and even an individual.

Therefore, the work of a physicist will always be. It can be said that it is still only the beginning of the development of science, although it seems that we know almost everything and everything is described. The modern world has stepped very deep into matter, which in turn has drawn a string of new discoveries and phenomena that were not previously known to man. Nevertheless, you should not treat science as something special. It is only a science and it is based on the personal observation of a person, and is in no way connected with reality. This is a side view. Yes, as a description of the phenomenon, it is true, but as a cause of what is happening, then there is no answer ... But probably a person will be destined to understand the meaning or method of organizing the material world. So far, all science is a theory, but it works, rockets fly into space, wells are drilled deep into the earth, cities are built, and so on.

**[Physics (from Ancient Greek: φυσική (ἐπιστήμη), translit. physikḗ (epistḗmē), lit. 'knowledge of nature', from φύσις phýsis "nature") is the natural science that studies matter and its motion and behavior through space and time and that studies the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behaves.](https://en.wikipedia.org/wiki/Physics)**
