Abstract: The Solvay Conference on physics，which began in 1911，was one of the earliest internationally renowned series of academic conferences，which had an important place in the history of physics because of the important impact on the development of physics. This paper divides the 26th Solvay physics，which is held on more than 100 years，into four core themes for a more systematic and in-depth discussion，sketched out the development of more than 100 years of physical characteristics，which also enriched the educational function of the history of physics.

Key words: Solvay conference on physics, quantum theory, particle physics, astrophysics, applied physics
