Philosopher Feynman said that no one in the world understands quantum mechanics because we know too little about quantum mechanics. Many of them are superficial cognitions and cannot touch the essence at all. We can only understand quantum mechanics. To describe the phenomenon we see, we cannot use past experience and knowledge to understand its mechanism and principles. We cannot even know why it is like that. This is what Feynman wanted to express.

Feynman was an outstanding physicist. He mainly studied quantum mechanics and had high achievements in quantum mechanics. In addition, he also participated in the Manhattan Project in the United States and received a Nobel Prize. Bell Prize in Physics. The courses he taught at universities during his lifetime were compiled and written into the book "Feynman Lectures on Physics" by later generations, which is very popular in universities around the world.

However, such a famous quantum mechanics researcher said that no one in the world understands quantum mechanics, and Bohr also said that anyone who says he understands quantum mechanics must not understand quantum mechanics. Mechanics?, two big guys in the field of physics are so awe-inspiring and so confused about quantum mechanics, how much confusion has quantum mechanics left to mankind? Physicists are confused about quantum mechanics mainly because the object of quantum mechanics research is the microscopic world. There are many deviant phenomena in that microscopic world, which cannot be explained by theory or experience. Maybe this time we It is found that if this is such a phenomenon, we may not be able to understand it if we repeat it exactly the same next time.

Einstein, the founder of quantum mechanics, studied quantum mechanics throughout his life. He was still confused about it before he died. He believed that quantum mechanics can only be close to the truth, but it is not the truth and it is incomplete. . There is a very elementary experiment in quantum mechanics called the double-slit experiment. A very strange phenomenon occurred in this experiment, that is, the results were different when someone was present and observed when no one was present. Ji Jiang went through repeated experiments. Experiment, the result is still the same. So far, no one knows what the principle of this experimental phenomenon is. All we know is that such strange phenomena exist objectively in the clinic.

Feynman said that no one in the world understands quantum mechanics, just like the double-slit experiment. No one in the world understands its principles.
