Mathematical physics is a mathematical theory and method aimed at studying physical problems.
Mathematical physics is a field of physics, and its purpose is to deduce the results for the established physical theory by mathematical solution under the premise of knowing the basic laws of physics.
2. Theoretical physics.
Theoretical physics is a subject that theoretically explores the basic laws of unknown material structure, interaction and material movement in nature. The research fields of theoretical physics involve particle physics and nuclear physics, statistical physics, condensed matter physics, cosmology and so on. , including almost all basic theoretical problems of physics.
