When Professor Lu Shenjian saw that Lu Zhou stopped writing, he smiled and asked, "You answered the previous two questions, why can't you answer this one?"
Lu Zhou raised his head and said, "Professor, have you researched string theory before?"
Professor Lu Shenjian smiled and answered, "I'm asking for your opinion, why does it matter if I have researched it before? Just write what you want."
Lu Zhou smiled and said, "Then can I just say it out loud?"
The professor smiled and said, "Yeah, go ahead."
Lu Zhou thought for a bit before he decided to tackle this question from two perspectives.
"This is just my personal opinion. I agree with Mr. Yang's point of view for the development of string theory. Physics is an experiment-based science, and theories cannot be confirmed only by mathematical representations."
