Chemistry is a practical subject, which, together with mathematics and physics, has become the basis for the rapid development of natural science. The core knowledge of chemistry has been applied to all fields of natural science, and chemistry is an important pillar of the powerful force to transform nature. Chemists observe and think about social problems from the viewpoint of chemistry, and analyze and solve social problems with chemical knowledge, such as energy problems, food problems, environmental problems, health problems, resources and sustainable development.
The intersection and infiltration of chemistry and other disciplines have produced many marginal disciplines, such as biochemistry, geochemistry, cosmochemistry, marine chemistry, atmospheric chemistry and so on. , make biology, electronics, aerospace, laser, geology, ocean and other technologies develop rapidly.
Cultivate the psychology of continuous progress, discovery, exploration and curiosity, stimulate people's desire to understand nature and enrich people's spiritual world.
Nowadays, chemistry is increasingly permeating all aspects of life, especially important issues closely related to the development of human society. In a word, chemistry is closely related to human clothing, food, housing, transportation, energy, information, materials, national defense, environmental protection, medicine and health, and resource utilization. It is a practical subject urgently needed by society.
