1, advanced mathematics
Advanced mathematics is a basic subject formed by calculus, algebra, geometry and their intersection.
The main contents include: series, limit, calculus, spatial analytic geometry and linear algebra, series, ordinary differential equations.
2. Electrodynamics
Electromagnetic phenomena's classical dynamics theory of electrodynamics. Also known as classical electrodynamics, electrodynamics is its abbreviation. It studies the basic properties and motion laws of electromagnetic field and the interaction between electromagnetic field and charged matter.
Up to now, electromagnetic interaction is the most complete, in-depth and widely used knowledge in nature, so it is of special significance to study electrodynamics, the basic theory of electromagnetic interaction that permeates all branches of physics. It has a higher foothold than electromagnetism, and it is more difficult to apply the foundation of mathematics, which is more theoretical, deeper and more popular.
3. Quantum mechanics
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.
4. Solid state physics
Solid state physics is a subject that studies the physical properties, microstructure, motion patterns and laws of various particles in solids and their relationships. It is an important branch of physics, involving mechanics, heat, acoustics, electricity, magnetism and optics.
5. optics
Optics is an important branch of physics. It is also a discipline related to optical engineering technology. In a narrow sense, optics is a science about light and vision. In the early days, optics was only used for things related to eyes and vision.
Today, optics is a science that studies the generation, propagation, reception and display of electromagnetic radiation and the interaction with matter in a wide range from microwave, infrared, visible light and ultraviolet to X-ray and γ-ray, focusing on the range from infrared to ultraviolet. It is an important part of physics.
