1, mathematics
Mathematics is a universal means for human beings to strictly describe and deduce the abstract structure and mode of things, and can be applied to any problem in the real world. All mathematical objects are artificially defined in essence. In this sense, mathematics belongs to formal science, not natural science.
2. Logic
Logic is an undergraduate major in colleges and universities, and it is a major that studies the forms and laws of thinking. Students in this major mainly study the basic theories and knowledge of logic, mathematics, computer science and philosophy, receive the training of axiomatic methods, formal methods and semantic analysis, and have the basic ability of professional research.
3, astronomy and astrophysics
Astronomy and astrophysics are astronomical terms, which come from the Chinese translation of astronomical terms approved and published by China Astronomical Terminology Examination Committee. The copyright of translated entries and Chinese and English explanatory materials belongs to the Astronomical Terminology Committee.
4. Earth science and space science
The research fields of earth science and space science extend from the interior of the earth to interstellar space, including different levels of structure and material composition, material movement and various physical and chemical processes in this vast area.
5. Physics
Physics is a subject that studies the most common laws of motion and the basic structure of matter. 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.
6. Chemistry
Chemistry is a basic natural science that studies the composition, structure, properties, transformation and application of substances at the atomic and molecular levels. It originates from life and production practice, and develops with the progress of human society.
7. Life sciences
Life science is a science to explore life phenomena and the laws of life activities, and it is a basic subject in natural science. Its research object is the structure, function, occurrence and development law of organisms. Its purpose is to clarify and control life activities, transform nature and serve the practice of agriculture, industry and medicine.
