1 1 years later, Einstein focused on his higher goal-general relativity, and finally gave the basic framework of general relativity at the age of 37. Since then, he has been perfecting this theory for many years, making concrete calculations (the nonlinear partial differential equation of general relativity is extremely difficult to solve, and until today, many physicists and even mathematicians are still studying its solution) and applying it to the whole universe. Cosmology in the modern sense was initiated by Einstein.
Although Einstein was disgusted with the basic characteristics of quantum mechanics, he made important contributions to the establishment and development of quantum mechanics. He himself once said, "I have been thinking about quantum mechanics for a hundred times longer than general relativity ...".
From putting forward light quantum in the early years, applying quantum theory to the study of specific heat for the first time, putting forward the theory of laser with quantum theory for the first time (laser technology was born more than 40 years after the theory was put forward), to strongly supporting De Broglie's material wave hypothesis (which laid the wave form of quantum mechanics and was inspired by light quantum hypothesis and relativity) in the 1920s, to strongly supporting Bose in the 1930s, and putting forward the famous bose-einstein statistics with him.
In the 1920s and 1930s, he had several far-reaching debates with the camp headed by Bohr on the nature of quantum mechanics. Although almost every argument ended in Einstein's failure, every argument gave scientists a deeper understanding of quantum mechanics. Today, it is still the core of quantum computer, quantum communication and quantum cryptography-entangled state was formally introduced into physics when Einstein put forward EPR paradox.
In the last thirty or forty years of Einstein's life, he devoted his main energy to the study of unified field theory, which was far from the mainstream of physics at that time (but basically the mainstream of physics at present and for a long time to come). In the words of born, who proposed the probability explanation of quantum mechanics, "this is a tragedy for both of us: he lost most of his companions and we lost our leader." His attempt also failed, but it was not meaningless. It at least points out that Einstein's method of focusing on the field theory of differential equations is not feasible, which will make it unnecessary for future generations to take this detour.
Einstein also published a large number of articles on society, politics, education, war and peace, many of which are profound (for example, in his article Why Socialism, he pointed out that the greatest danger of the socialist system is that it is easy to slide to autocracy), and his writing style is beautiful (the Chinese translation of the Collection of Einstein's Later Years calls him a master of using German).
..... Einstein is the pride of mankind, so I suggest spending some time reading his biography and even his own articles. He died of illness at the age of 76, so I suggest not to use the unpleasant word death. )
As for the rumors that Einstein participated in the research of secret weapons, psychics and aliens. It's almost certain that it's just a fabrication by film writers or people with ulterior motives. Because, first of all, Einstein himself was obsessed with studying things related to the nature of the universe. Although the above things are mysterious, they are all so-called "details", and Einstein will not be too interested in them; Secondly, for western governments, Einstein is a "thorn in the side", his color is red (he once praised Lenin and his October Revolution), and things like weapons research are afraid of Einstein's participation. For example, the Manhattan project, although Einstein's famous letter to Roosevelt played a certain role in promoting the project, was completely excluded. McCarthyism, the anti-* * frenzy in the United States in the forties and fifties, is a criticism of Einstein. In this case, let alone what secret things the government will ask him to cooperate in, even the relevant research that the people may have will be used as a handle to attack Einstein. He once publicly appealed to American intellectuals to keep their conscience, not to succumb to pressure and commit perjury (the darkness in the United States is a bit like during the Cultural Revolution), and to be prepared to go to jail for it. ...
