In recent days, the institute's doctors have been discussing Song Zimo's words.
After several days of pondering, everyone seemed to understand a bit; classical mechanics has encountered a crisis, and it's time for relativity to take the stage.
"Did everyone understand what I said?" Song Zimo asked everybody again in the afternoon.
Someone shook their head: "Didn't understand it at all."
Another graduate student was a bit puzzled: "Isn't this very simple? Why say so much? I, for one, find it simple; I understood it all."
Song Zimo said: "Actually, those who didn't understand might end up understanding, while those who said they did probably understood nothing, and it will be very difficult for them to understand in the future."
