About science:

Science 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, which indicates 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. Peking University, Fudan University, Tsinghua University, Nanjing University, China University of Science and Technology, Beijing Normal University, etc.

In a narrow sense, science is a subject chosen by liberal arts and sciences in senior high schools.

Physics in 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. An eternal theme of physics is to find all kinds of order, symmetry and symmetry breaking, conservation laws or invariance.

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 the physics of destruction and virtual demolition 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.

Biology in science:

Biology is a branch of natural science, which studies the structure, function, occurrence and development of organisms and the relationship between organisms and their surrounding environment. Biology originated from natural history, experienced experimental biology and molecular biology, and entered the period of systematic biology.

The main branches of high school biology are biochemistry, molecular biology, cell biology, genetics, embryology, neurobiology, immunology, morphology, ecology, modern biotechnology and so on.
