There is a widely circulated myth that Einstein was slow to respond when he was a child, and even said that he was mentally ill. However, a more comprehensive study of his early life, such as Brian's viewpoint in the biography of Einstein published in 1996, has questioned this legend. Einstein was very good at mathematics when he was a child. At the age of 10, he can discuss mathematical problems with a Polish medical life named Talme. Talme goes to his house for lunch once a week. In order to satisfy Einstein who was full of curiosity, Talme showed him some books, especially Bernstein's works. Bernstein is a popular science writer. In his book, he mentioned that there is a unified force in various natural phenomena and discussed this view.

Not all the stories circulated are nonsense. It is said that when Einstein was studying at Ritter Polder Middle School in Munich, his Greek class was poor, and the teacher looked down on him and said that he knew nothing in front of the whole class.

However, in the process of Einstein's personality maturity, there is no doubt that Einstein is full of enthusiasm like fire. "He is a passionate young man," said biographer Brian. "On one occasion, he was walking in the street with his violin on his back, when he suddenly heard someone playing the piano in a roadside room. So he rushed in. When he ran upstairs following the sound of the piano, the woman who played the piano was dumbfounded by him, but he ignored it and said,' Keep playing, keep playing'. He also said that he took out his piano to accompany her. He has an unusually natural nature. "
