First, topology

Topology is a basic language of modern mathematics, and there are thousands of Qian Qian structures in mathematics that cannot be separated from topology. Topology is a very abstract branch of mathematics and a branch of geometry, as long as we study the properties of geometric figures that remain unchanged under continuous deformation.

Second, pharmacology.

Pharmacology is a bridge between basic medicine and clinical medicine, medicine and pharmacy. Clinical practice is conducted under the guidance of pharmacological theory, which is enriched on the basis of experimental research. The key to learn this course well is rote learning, which is different from the relevance and logic before and after some courses are recited. This course has no logic and connection at all.

Third, real variable function

The theory of real variable function is an important branch of mathematics, which is the deepening and popularization of mathematical analysis. Its fundamental significance lies in solving the integral problem. There is a saying in mathematics major: Learn real variable function ten times, and functional analysis will make you chilling. This course is also called quantum mechanics in mathematics.

Fourthly, phonology.

Phonology is a traditional knowledge to study the sound, rhyme and tone system and its development law in various historical periods of ancient Chinese. Phonetics is constantly changing in the process of historical development. In ancient times, there was no scientific voice recording tool. It is quite difficult to learn to combine Chinese character labeling and analyze pronunciation, which is called "Juexue".

Verb (abbreviation of verb) quantum mechanics

Quantum mechanics is a theory that describes microscopic matter, and together with relativity, it is considered as the two basic pillars of modern physics. Many physical theories such as atomic physics, solid state physics, nuclear physics and other related disciplines are based on quantum mechanics.

The quantum mechanics of the university course difficulty top 1 is introduced as follows:

Quantum mechanics, a theory of physics, is a branch of physics, which studies the motion law of microscopic particles in the material world. It mainly studies the basic theories of atoms, molecules and condensed matter, as well as the structure and properties of nuclei and elementary particles.

Together with the theory of relativity, it forms the theoretical basis of modern physics. Quantum mechanics is not only one of the basic theories of modern physics, but also widely used in chemistry and many modern technologies. ?

At the end of 19, people found that the old classical theory could not explain the microscopic system, so through the efforts of physicists, quantum mechanics was established at the beginning of the 20th century to explain these phenomena.

Quantum mechanics has fundamentally changed people's understanding of material structure and its interaction. Except gravity described by general relativity, all basic interactions can be described within the framework of quantum mechanics (quantum field theory).
