Initial stage (16th century to17th century). A "scientific revolution" broke out mainly in the fields of astronomy and mechanics, and Newtonian mechanics was born. Digestion and gradual stage (18th century). Analytical mechanics has been established, and great progress has been made in optics, thermodynamics and electrostatics. The heyday (19th century).

Physics (physics)

It is a subject that studies the most general laws of motion and the basic structure of matter. Physics, as the leading discipline of natural science, studies the most basic motion forms and laws of all substances from the universe to elementary particles, so it has become the research basis of other natural science disciplines.

Physics began in the era of Galileo and Newton, and now it has become a basic science with many branches. Physics is an experimental science, and it is also a science that advocates rationality and attaches importance to logical reasoning. Physics, which makes full use of mathematics as its working language, is the most accurate natural science subject today. 202 1, China's physical natural index ranks first in the world.

Physics is a natural science.

Attach importance to the study of matter, energy, space and time, especially their respective properties and their relationships. Physics is knowledge about the laws of nature; More broadly, physics explores and analyzes what happens in nature to understand its laws. Research objects of physics: physical phenomena, material structure, material interaction, and laws of material movement.

Condensed state physics-the study of the macroscopic properties of substances, which contain a large number of components and have strong interaction between them. The most familiar condensed phases are solids and liquids, which are formed by bonds between atoms and electromagnetic forces. More condensed phases include superfluids and Bose-Einstein condensed states (found in some atomic systems with very low temperatures).

Superconducting phases of conducting electrons in some materials: ferromagnetic and antiferromagnetic phases in atomic lattice. Condensed matter physics has always been the biggest research field. Historically, it originated from solid state physics. 1967 was first put forward by philip anderson and adopted this name.
