The afternoon classes started at two o'clock, and at half past one, the large classroom was already overcrowded.
Many students came to the classroom to reserve seats after lunch. Some even came as early as twelve o'clock, and those who came after 1:30 simply couldn't find a seat.
Some teachers who came in were very surprised when they saw this scene. They cried and laughed when they took a closer look.
It is impossible for so many students to be graduate students or doctoral students in the Department of Mathematics or Physics. Many of them are juniors and seniors.
They came because they heard about Wang Hao's lectures.
After all, it was a formal open class. Students who came to attend the lecture on their own initiative could not be kicked out, and they could not find seats because they arrived late. Later, several teachers simply moved chairs to the nearby office, right in front of the edge aisle, or
I only sat down after adding chairs in the back row.
At the same time, there was a lot of discussion in the classroom, "Professor Wang finally started classes again!"
"I came here specifically to listen to Teacher Wang's lectures. Those of you who haven't heard of it may not know that Teacher Wang's lectures are very good!"
"Mr. Jones was giving the lecture in the morning, and that Amerikan man was not good at all. He couldn't understand anything he was talking about..."
"Me too, I don't understand it at all..."
"His Chinese level is not good yet, but he speaks very fast. How can he listen?"
"It seems that the afternoon class will be connected to the morning class, right? Is it possible for it to be so difficult?"
"I don't know, but I have to listen anyway..."
Paul Phil-Jones walked into the classroom amidst the commotion.
He entered the classroom from the main entrance. Seeing the crowded scene, he immediately stood at the door and rubbed his eyes vigorously, "Why are there so many people?"
Many students left in the morning.
The afternoon classes connected with the morning classes, and normally not many students would come to attend the classes. He thought that few people would be there, and he was still worried about Wang Hao's classes, but he saw a scene like this.
Paul Phil-Jones was stunned for a long time. He didn't know whether to go in because he knew he couldn't find a seat. Fortunately, Zheng Yaojun also came. He sat on the side of the first row and faced the door.
Wave, "Paul, here!"
Paul Phil Jones looked up and simply walked over and sat in the seat reserved by Zheng Yaojun.
After sitting down, he asked in surprise, "Zheng, why are so many students here?"
"What's the big deal?"
Zheng Yaojun said nonchalantly, "Many students still don't know this, otherwise the classroom wouldn't be able to accommodate it."
"Is Wang Hao's course so popular?"
"Of course."
"But the content of his lecture is connected to the morning..." Paul Phil-Jones hesitated for a moment and continued, "There are not many people left in the morning."
Zheng Yaojun pursed his lips hard and didn't know whether he should answer the call. He was also present in the morning, and he couldn't keep up with what Paul Phil Jones said.
He specializes in academic fields. He is a scholar in the field of partial differential equations and naturally has no research on theoretical physics.
But considering that Wang Hao was going to give a lecture, he still came because Wang Hao's lectures were notoriously high and he had attended the lectures several times, so he felt it was necessary to come.
Zheng Yaojun did not answer, and the topic could not continue.
soon.
Wang Hao came to the classroom.
When Wang Hao stood on the podium, the classroom suddenly became quiet. He looked at the number of people in the classroom, and he was not surprised.
One is reputation and the other is teaching level.
As long as he holds open classes, there will never be fewer people coming.
Wang Hao was still a little depressed about the content of the explanation, because it connected with the content of the morning course, and most people did not understand the morning course.
He still thought of a way.
Many teachers and students in the audience also wanted to see how Wang Hao would start the course.
At this time, Wang Hao said with a smile on his face, "This lesson is about connecting
Mr. Wu Jones’s course starts from the four-dimensional space.”
"But before the class, let's review the morning class first."
He officially entered the explanation.
Of course, Wang Hao would not explain the content of the morning again. He just went through the knowledge points and then wrote several conclusions and methods that needed to be used one by one on the whiteboard that was placed.
This process took about half an hour.
Although there was no specific explanation, the conclusions and methods of the morning knowledge points were repeated several times in succession, and time was given for students to record them carefully.
Then we entered into the formal explanation.
At this time, it becomes much smoother to move on to the next step of content explanation.
"Under the premise that the speed of light remains constant, the special theory of relativity's space-time view has reshaped humankind's understanding of the universe."
"Space and time are no longer isolated from each other, but are connected by the movement of matter, forming an inseparable whole..."
"After establishing a new view of time and space, a more elegant mathematical form will inevitably be needed to unify the three-dimensional space and the one-dimensional time under the same framework. This is the concept we have heard of -
Four-dimensional space-time.”
「…………」
After the opening introduction, the course is entering the formal content.
There are a lot of complex mathematical analysis contents in the middle, and Wang Hao will explain in detail the key and difficult issues.
If he encounters content related to the morning course, he will directly quote the conclusions and methods listed on the whiteboard to make students understand better.
With the improvement of understanding in "Feedback from Teaching", most of the graduate students and doctoral students in the classroom can roughly understand it.
Undergraduate students with no basic knowledge can also understand the general content.
When you find that you can understand such profound knowledge, it will undoubtedly arouse students' interest, and they will naturally listen more carefully.
This also allowed Wang Hao to receive a large amount of gifts of knowledge and understanding, even more than he expected, because some knowledge related to the content explained by Paul Phil-Jones was also directly given back to him.
Wang Hao was very surprised. During the break during the course, he thought about it carefully and understood it.
Because everyone did not understand the knowledge explained by Paul Phil-Jones, but he listed the relevant content on the whiteboard and continued to quote it, which naturally stimulated thinking and understanding of relevant knowledge.
Now I feel that after giving a one-hour class, I can always give back more knowledge and understanding.
"That's not bad!"
"It seems that it would be helpful to have Paul give lectures in advance..."
"Although the students didn't understand it, it doesn't prevent me from improving the efficiency of my teaching feedback."
Wang Hao thought a little strangely.
Paul Phil-Jones sat on the side of the first row and listened carefully. He found that Wang Hao's explanation was indeed very good, and he felt that it was very rewarding.
There were some contents that I didn’t understand so deeply before, and I didn’t think about that much, but after Wang Hao explained them, I felt that I understood them more clearly.
Such a small gain is difficult for Paul Phil-Jones to appreciate, because most of the knowledge content is meaningless to him.
What made him depressed was that he didn't see what happened in the morning.
During the break, he looked back carefully and found that not many students left at all, most of them stayed in the classroom, and everyone listened very seriously.
Waiting until the class is over, that is, nearly three hours later, the classroom is still overcrowded, even more than at the beginning, because there are more than 20 students standing in the last row, who obviously walked in later.
People who can't find a seat.
When he thought about the situation in the morning carefully, he suddenly felt restless.
I gave a lecture and all the students left.
When Wang Hao lectured, he continued to connect his own content. Not only did the students not leave, they listened with great interest, and more and more people came.
This gap is also too big.
After the classes were all over, Paul Phil-Jones walked out of the classroom feeling a little depressed.
When Wang Hao saw him looking sad, of course he knew why, but he still felt that he should give him some comfort, "Paul, don't worry about it."
