There are many sayings that Einstein was not clever when he was a child. For example, he didn't speak until he was four, and he didn't start to read until he was seven. In fact, he was good at math and physics since he was a child. When others were still studying elementary mathematics, he mastered calculus (advanced mathematics) at the age of fourteen. Is such a person still stupid? This is obviously a genius, okay?
Einstein seldom spoke when he was a child, and his teacher never liked him very much. Later, he likes to delve into problems and do things that require brains and hard work. But true cleverness and stupidity are not judged by those teachers, but by one's interest and endurance. There is a saying that genius is one percent intelligence and ninety-nine percent perspiration.
During his college years, Einstein began to emerge, and he was able to publish physics papers at the age of 2/kloc-0. It may not be a big deal for many people. After all, there were still many blank fields in physics at that time, which was not as comprehensive as it is now. Actually, it's not. At that time, the traditional physical theory was already perfect, and there was basically no room to drill, which was the bottleneck. Just like our physics today, it looks very prosperous, but everyone who studies physics knows that the current physics theory is very perfect and it is difficult to make a breakthrough. So Einstein was only 2 1 year old and was able to publish his own theoretical papers, which was not easy.
By the age of 26, he had completely fought back. This year, he put forward the special theory of relativity independently and completely, which initiated a new era of physics. Since then, it has been out of control, and various records have been frequently brushed, which shocked the world for a while. Therefore, this year is called "Einstein miracle year".
