If friends are really good at physics, they should not only be interested in physics experiments. Because physics experiment is a systematic process related to mathematical calculation, chemical experiment, logical reasoning and other disciplines, which promote each other and are mutually causal. Without the support of comprehensive and complete basic knowledge of physical chemistry and mathematics, there is no way to complete or realize physical experiments. Therefore, it is necessary to persuade friends to study and master basic courses such as physical chemistry and mathematics seriously, so as to better complete or innovate new realization methods and achieve excellent career achievements.
