The seven undergraduate majors in science are ranked as follows:

1, Mathematics and Applied Mathematics: 7th place.

Mathematics and applied mathematics: Mathematics and applied mathematics mainly focus on the theoretical research of mathematical application, including arithmetic, algebra, geometry and so on. They mainly use mathematical knowledge to analyze and solve some problems in life, such as data analysis behind stock ups and downs, predicting the probability of an event, and using computers, MATLAB and other software to deal with some complex operations that the human brain can't solve, such as pi.

2. Information and Computing Science: 7th place.

Information and Computing Science: It is a major combining mathematics with computer. While cultivating mathematical foundation and mathematical thinking ability, I can skillfully use computers to calculate complex mathematical problems with the fastest algorithm, such as using computer programming to simulate complex function images, calculating high-order matrices, and calculating pi. It is more convenient to solve mathematical problems through computer processing. ?

3. Physics: 6th place.

Physics mainly studies the laws of motion and the basic structure of matter, and it is knowledge about the laws of nature. It explores and analyzes the phenomena that occur in nature, so as to understand their causes and processes, such as the formation and process of lightning and rain, the running laws of planets in the universe, and the reasons for short circuits in life. ?

4. Applied physics: second place.

Applied physics mainly studies the basic theories and methods of physics, including the applied basic knowledge, basic experimental methods and technologies of electronic technology, computer technology and optical fiber communication technology. Most of the optical sensing instruments in life, such as infrared detectors, induction recognition doors and laser pens, come from this major.

5. Chemistry: 10.

Chemistry mainly studies the basic theoretical knowledge of chemistry and the basic operation skills of chemical experiments, including chemical reactions and changes within a single substance and between various substances, and understands the mechanism and process of their changes, such as burning goods, rusting steel, food decay, food brewing and other processes, all of which are chemical changes. By studying the process of these changes, we can understand the reasons and mechanisms of their changes.

6. Biological Sciences: 3rd place.

Biological science involves a wide range of fields, including botany, zoology, microbiology, neurology, physiology, histology, anatomy and so on. , mainly studies the structure, physiological behavior, origin, evolution and genetic development of organisms, such as human tissue structure, human heredity, bacterial culture and genetic engineering.

7. Biotechnology: 2nd place.

Biotechnology mainly studies the basic theories, knowledge and skills of modern biology and biotechnology, including molecular biology, microbiology, genetic engineering, fermentation engineering and cell engineering. Mainly use biological substances to improve products, improve animals and plants, or cultivate microorganisms for special purposes. Common cloning, gene recombination technology and biological vaccine cultivation all belong to this.
