Extended data
Einstein is great, on the one hand, because he knows some mathematics and has the ability to appreciate the wonderful things in mathematics intuitively; On the other hand, he also has his own understanding of the phenomena in physics.
What makes him different is that he can see both closely and far. It's like there are both close-up and distant views in the movie; It would be great to be able to switch freely from near to far. Most people only have one lens, or they can only watch it at close range, or they can only watch it at a distance, and they will not switch freely.
