What does quantum mechanics calligraphy mean?

Quantum mechanics is difficult. Because quantum mechanics is a very difficult science, the calculated formulas and data are as difficult to understand as the words in calligraphy. As a theory of physics, quantum mechanics is a branch of physics, which studies the motion law of microscopic particles in the material world. It mainly studies the basic theory of the structure and properties of atoms, molecules, condensed matter, nuclei and elementary particles. Together with the theory of relativity, it forms the theoretical basis of modern physics.
