Physics is a subject that studies the laws of motion and change of objects. It is the cornerstone of the natural science building and the foundation of the whole science and engineering discipline system. Its purpose is to promote the development of various disciplines based on physics through the study of physical theory, knowledge and experimental methods. Physics is one of the oldest natural disciplines. Because of its foundation and importance, it has maintained a steady development momentum. Especially with the appearance of relativity, the rapid development of quantum mechanics and the understanding of nonlinear science, physics has jumped to a new level.
