Many people had come to Shen Zhijin's lecture this time.
The entire auditorium was full.
Ning Li looked at Shen Zhijin who was standing on the stage.
Looking at his current appearance, it was really difficult for people to associate him with the previous image of him nervously and helplessly coaxing a little girl.
He had devoted his whole life to scientific research and could almost be said to have devoted his entire life to physics.
However, it turned out that in addition to this, he actually still cared about other people and things.
The topic of his lecture today was gravitational wave detection, but it was simple and in-depth. Even many non-related professionals were very engrossed as they listened to it.
The lecture lasted two hours, and the last 15 minutes was the free-question session.
The first two people had asked more professional questions, which Shen Zhijin had then answered in turn.
