relativity
Theory of relativity is the theory of time and space, which is mainly founded by Einstein. According to the different objects of study, it can be divided into special relativity and general relativity. The theory of relativity and quantum mechanics has revolutionized physics, and they have laid the foundations of modern physics. Relativity greatly changed the human concept of "common sense" of the universe and nature, and put forward the new concept of "simultaneous relativity", "four dimensions" and "time of bending". But in recent years, there has been a new understanding of the classification of physical theory - whether its theory is deterministic to classify classical and nonclassical physics, that is, "nonclassical = quantum". In this sense, relativity is still a classic theory. ...
