First, mathematics:
Mathematics is one of the most basic subjects in pure science, which mainly studies the abstract nature of concepts such as quantity and space. Mathematics is widely used in various fields and is a basic tool in natural science, social science and engineering technology. Mathematics involves many branches such as arithmetic, algebra, geometry and calculus, which is of great significance for cultivating students' logical thinking and reasoning ability.
Second, physics:
Physics is a subject that studies the basic properties and laws of motion of matter, mainly including the study of force, heat, sound, light, electricity and magnetism. The development of physics plays an important role in promoting human scientific and technological progress and understanding nature. For example, the formation and application of Newtonian mechanics, electromagnetism and quantum mechanics have greatly promoted the progress and development of human society.
Third, chemistry:
Chemistry is a subject that studies the composition, structure, properties and changes of matter. It mainly involves the study of elements, compounds and chemical reactions. Chemistry is widely used in industrial production, energy development, environmental protection and other fields, such as chemical production, drug synthesis, pollutant treatment and so on. The development of chemistry is of great significance for improving the quality of human life and developing the national economy.
Fourth, biology:
Biology is a subject that studies the structure, function, origin, evolution and distribution of objects, mainly involving zoology, botany, microbiology and molecular biology. The development of biology plays an important role in promoting human understanding of the nature of life and protecting biodiversity.
As a basic discipline of natural science, pure science plays an important role in human understanding of nature and promoting scientific and technological progress. Strengthening pure science education and developing scientific research are of great significance for cultivating innovative talents and improving national scientific and technological strength. The development of pure science needs to be combined with other disciplines and application fields to achieve better transformation and application of scientific and technological achievements.
