Why did Yang Zhenning, who talked with Einstein for an hour and a half, admit afterwards that he got nothing?

Because Yang Zhenning was not particularly famous at that time, and his theoretical research was not very strong, it was understandable that he could not understand Einstein, who was already called the God Man at that time, because his knowledge level at that time might not be enough for him to understand Einstein's meaning. In addition, because Einstein was born in Germany and suffered from senile diseases in his later years, his language began to be a little defective, and he occasionally spoke a few words of his hometown dialect, which made Yang Zhenning completely incomprehensible.

On the other hand, Yang Zhenning visited Einstein's office, sitting opposite an idol-level master. He is a little strange and nervous about Einstein, and his brain is buzzing, and he can't remember what he said. Summing up two objective reasons, I realized that Yang Zhenning didn't lie to us, just because he was too straight to be accepted. But when you think about it, it's not unreasonable. If you don't understand, what can you talk about getting wisdom? Therefore, it is understandable that Yang Zhenning got nothing.

We are all the greatest physicists in the 20th century, Einstein, who undoubtedly ranks first with Newton in the whole history of physics. Besides Einstein, the greatest physicists in the 20th century are mainly the founders of quantum mechanics, including Planck, Bohr, Heisenberg, Schrodinger, Dirac, Pauli, Born, Wei Gena and others in the early days of the establishment of quantum mechanics. Yang Zhenning called this era the gold mine era and his post-World War II era the silver mine era. However, Yang Zhenning was the leader of the silver mining era, and his contribution was equal to Feynman and Landau. Among the living physicists, only gherman, Weinberg and others can compete with Yang Zhenning. The rest, in Yang Zhenning's view, are people from the copper mine era.

So the gap between Yang Zhenning and Einstein is the founder of quantum mechanics. Among the greatest physicists in history, Yang Zhenning is definitely not in the top ten, but it is still possible to enter the top twenty. Of course, ordinary people cannot understand physics. I think Yang Zhenning should be a myth and legend. So although Yang Zhenning didn't understand Einstein at that time, it didn't prevent him from becoming a great man of science.
