Enter the Immortal Cultivation

All the students under Landau were like dishes in a tragedy, because Landau's IQ was too high and his students couldn't understand what he said. When Landau was teaching, he simply hung a picture on the blackboard, a shepherd was playing a flute, and a group of sheep were eating grass next to him. The students were puzzled and had to ask questions to Landau at the risk of being scolded. In fact, what Landau meant was "playing the lute to a cow".

After Landau found that his students couldn't understand what he was saying, he raised the threshold for his students to go out to an abnormal level. If you were born in the Soviet Union and heard that Landau's graduate school was extremely difficult to pass, and you are ready to challenge yourself, first of all, you need mathematics, secondly physics, and thirdly mathematics.

All students under Landau had to prepare a thick notebook and do thousands of questions. In the end, Landau would personally give you questions, involving all aspects of theoretical physics, and the mathematics part alone was enough to make people run away. The emotions of students who saw the test paper for the first time might be like this: why is it so thick? I hit the wall - why can't I look up the book? I hit the wall again - why are the physics concepts so difficult? I hit the wall - I can't solve the mathematics, I might as well die.

In the Soviet generation, only more than 40 people successfully passed the test, and later all became the backbone of the Soviet theoretical physics community.

Landau's idea was probably like this: since there was no way to help them with low IQ, he had to help them lay a good foundation. It's just that the foundation in his standard is not quite the same as others.
