Science and engineering is a broad field, including physics, chemistry, biology, engineering, astronomy, mathematics and the first six categories of various disciplines. It is actually the general name of nature, science and technology.

1 astronomy

It studies 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.

2. Engineering

Engineering is the application of science and mathematics. Through this application, we can make the characteristics of natural matter and energy through various structures, machines, products, systems and processes, and make efficient, reliable and useful things for human beings in the shortest time and with the least manpower and material resources. The general name of all disciplines formed by applying the theory of natural science to specific industrial and agricultural production departments.

3. Biology

Modern biology is a huge and eclectic field, which consists of many branches and disciplines. However, despite the wide range of biology, there are some universal and unified concepts that dominate all learning and research and integrate it into a single and coherent field. Generally speaking, organisms recognize that cells are the basic unit of life, genes are the basic unit of heredity, and evolution is the engine to promote the synthesis and creation of new species.

4. Chemistry

Chemistry is a natural science, which studies the composition, properties, structure and changing laws of matter at molecular and atomic levels. The science of creating new substances. The content of chemistry is generally divided into seven categories, including biochemistry, organic chemistry, polymer chemistry, applied chemistry and chemical engineering, physical chemistry and inorganic chemistry, with seven branches.

5. Physics

Physics is a subject that studies the most general laws of material movement and the basic structure of material. The main courses of general physics are: advanced mathematics, mechanics, heat, optics, electromagnetism, atomic physics, solid state physics, structure and physical properties. The main courses of theoretical physics include: mathematical physics methods, theoretical mechanics, thermodynamics and statistical physics, electrodynamics, quantum mechanics, introduction to computational physics, etc.
