Data expansion:
Science department refers to formal science and natural science. Science subjects mainly include: mathematics, logic, informatics, computer science, system science, physics, chemistry, biology, earth science and astronomy. The birth and development of science is the result of the development of human wisdom.
It marks that human beings really know how to think about nature, so the development of science is also the key to the development of human science and natural thinking. Well-known universities in science in China include Peking University, Fudan University, Tsinghua University, Nanjing University, University of Science and Technology of China, Beijing Normal University, etc.
Mathematics is a subject that studies concepts such as quantity, structure, change and spatial model. By using abstraction and logical reasoning,
It is produced by counting, calculating, measuring and observing the shape and movement of objects. Mathematicians have extended these concepts in order to express new conjectures with formulas and establish strictly deduced truths from properly selected axioms and definitions.
Mathematics is a general means for human beings to strictly describe the abstract structure and mode of things, and all mathematical objects are artificially defined in essence. In this sense, mathematics belongs to formal science, not natural science.
Physics is a natural science that studies the structure, interaction and movement of natural materials. It is a natural science based on observation and experiment. Its achievements are of positive significance for human beings to understand nature scientifically and get rid of superstition.
The actual physical phenomena and laws are generally complex and involve many factors. Discard the secondary factors and grasp the main factors, thus highlighting the essential characteristics of objective things, which is called establishing a physical model. The essence of physics is to establish a physical model for the research object, study the model through mathematical tools, and then explain and predict the research object.
Physical model (schematic diagram), physical formula (mathematical symbol), physical law (written description), physical image (functional image between two physical quantities) and physical explanation (physical meaning) constitute the basic forms of physical knowledge, and they are all important components of physical language.
