After the lecture, Lu Zhou spent around ten minutes answering the student's questions. He then put away the textbook and left the classroom.
Perelman, who was sitting at the back of the classroom, stood up and followed Lu Zhou out of the classroom.
He had a pensive look on his face as he suddenly spoke.
"That was a normal lecture."
Lu Zhou smiled and said, "It's only a class for undergraduate students."
Perelman: "Why do you teach undergraduate students?"
Lu Zhou: "Because revisiting what makes the obvious, obvious, can help us understand what makes the complex, complicated… In fact, this is what Fermi thought as well, and I agree with him. Maybe some of my students will become Fields Medalists, that will be very fulfilling."
Perelman's expression didn't change.
His attitude toward mathematics was always a pursuit of purity. Therefore, he did not resonate with Lu Zhou's words at all.
He thought for a while and spoke.
