Mathematics is a discipline that studies the concepts of quantity, structure, change, space and information, and belongs to a formal science from a certain point of view. Mathematics plays an irreplaceable role in the development of human history and social life, and it is also an indispensable basic tool for studying and studying modern science and technology.
Physics is a science that studies the most common laws of motion and interaction in nature, as well as the basic existing state and structural level of matter. This is a natural science based on experiments. An eternal theme of physics is to find all kinds of order, symmetry and symmetry breaking, conservation laws or invariance. All natural phenomena will not violate the laws of physics, so physics is the foundation of other natural sciences and all modern science and technology.
Chemistry: It is a science that studies the composition, structure, properties and changing laws of matter. The world is made of matter, and chemistry is one of the main ways and means for human beings to understand and transform the material world. From the primitive society in which fire was used to the modern society in which various artificial substances were used, human beings are enjoying the fruits of chemistry. Human life can be continuously improved and improved, and the contribution of chemistry plays an important role in it. Chemistry is closely related to human progress and social development, and its achievement is an important symbol of social material civilization. Therefore, chemistry is "the foundation, core and backing of material science", and it is a discipline with a long history and full of vitality.
Biology: Also known as biological science, it is a science that studies the essence, characteristics, occurrence and development of life phenomena and activities. It can be used to effectively control life activities, actively transform the biological world and benefit mankind. Biology is closely related to human survival, people's health, economic construction and social development, and it is the most concerned basic natural science in the world today.
Astronomy: It is the study of the structure and development of celestial bodies and the universe in space. The contents include the structure, properties and operating rules of celestial bodies. By observing the radiation emitted by celestial bodies to the earth, we can find and measure their positions, explore their motion laws, and study their physical properties, chemical composition, internal structure, energy sources and their evolution laws.
Earth science: It is a basic discipline to study the process, change and interaction of the earth system (including the atmosphere, hydrosphere, lithosphere, biosphere and the space between the sun and the earth). It mainly includes geography (including soil science and remote sensing), geology, geophysics, geochemistry, atmospheric science, marine science and space physics, as well as emerging interdisciplinary subjects (earth system science and geo-information science).
