Physics is a subject that studies the most general laws of material movement and the basic structure of material. Physics, as the leading discipline of natural science, studies the most basic motion forms and laws of all substances from the universe to elementary particles, so it has become the research basis of other natural science disciplines.

Its theoretical structure takes mathematics as the working language and experiment as the only criterion to test the correctness of the theory. It is the most accurate natural science discipline today.
