"Everyone should try to find a place to sit down first. If you really don't have a place, you can wait until the next opportunity to sign up. If you want to take photos and sign autographs, please come to me after the open class is over."
Xu Yun seemed a little surprised. He did not expect that his first public class would attract so many students to sign up.
Stand on the podium to reassure everyone and maintain order, and then insert the courseware disk into the multimedia.
Fortunately, he has a relatively high prestige among his classmates, and the noisy classroom immediately became quiet as soon as he finished speaking.
However, no one chose to leave. Even if they stood for two hours, they still wanted to finish the lecture.
Seeing that his classmates persisted, he didn't feel like saying anything, so he had to let them listen to the class like this.
Seeing that the official class time was about to arrive, several figures appeared at the door of the classroom again.
Qin Xiangxin, dean of the Department of Mathematics, led the team and led two professors, Tang Yanshan and He Antai.
"It's quite lively."
"Your open classes are now the most popular among students." Qin Xiangxin walked in first, glanced over his head and looked at the attendance rate in the classroom, then faced Xu Yun again and suggested with a smile: "How do you feel? Do you have any plans every week?" How many more events will be held in the department?”
"this……"
Xu Yun was speechless when he heard this and did not give a clear response.
Today's open textbook is the dean's suggestion. If he really agrees to come every week, he will be no different from a lecturer.
As a student who is about to graduate from an undergraduate degree, learning should still be the goal.
Qin Xiangxin apparently said that casually, and then did not continue to ask any further questions.
Without waiting for Xu Yun to answer, he walked towards the back row with a smile on his face.
Tang Yanshan and He Antai just nodded slightly and followed Qin Xiangxin.
The smart students in the back row quickly gave up their seats when they saw the dean and two professors approaching.
"Dean."
"You guys sit here."
"OK."
Qin Xiangxin and the others did not refuse. They cast admiring glances at these students and then sat down.
As the open classes officially started, the classroom with little space left became very quiet again.
It is no exaggeration to say that you can hear a needle drop.
Everyone is paying full attention to this lecture, for fear of missing any important link.
Facts have proved that Xu Yun did not disappoint everyone. Following the courseware, he talked about the origin of abstract algebra and its extension.
and the various branches included.
Group theory.
Ring theory.
Garava theory.
Linear algebra.
In addition, he also uses practical examples to explain, presenting an abstract algebra that is no longer abstract.
And soon everyone in the classroom was surprised to find that there seemed to be a kind of magic in what Xu Yun was talking about, making people involuntarily immersed in it without feeling bored.
This is a state that is not found in normal classes.
Abstract algebra is a difficult subject in undergraduate mathematics courses, and it makes many people feel overwhelmed.
But now after listening to this open class, I feel a sudden enlightenment.
It seems that abstract algebra is not that abstract either.
Even the examples given in class were not difficult.
Originally, most people signed up to attend this open class because of Xu Yun's fame.
While admiring the prowess of the world's math problem provers, you can take a group photo and get an autograph or something, and maybe you can protect yourself from failing the exam and getting into college smoothly.
But after really listening to it, I later realized that Xu Yun was not only capable of proving difficult problems.
He is also very good at teaching.
He even had an idea in his mind that it would be great if Xu Yun could be his lecturer.
The more immersed you are in something, the faster time usually passes. Before you know it, the two-hour open class is coming to an end.
During this period, several professors, including Qin Xiangxin, frequently nodded in affirmation of what Xu Yun said.
Among them, Tang Yanshan was even more secretly frightened.
I remember that when Xu Yun first entered the school, he asked him to explain the monthly exam questions to his classmates.
At that time, he discovered Xu Yun's special talent, being able to simplify complex problems and get to the core.
Help others quickly understand the problem.
He is simply a born teacher.
Now that so much time has passed, he can clearly feel that Xu Yun's talent in this area has improved a lot.
Tang Yanshan himself is a professor and graduate tutor. In his opinion, this talent is more valuable than personal ability.
After all, cultivating a group of outstanding mathematical talents is completely different from reaching a certain level yourself.
"Abstract algebra has become the universal language of most contemporary mathematics after the foundation and development of successive mathematicians."
“I hope everyone will be able to master this subject and learn its various branches.”
"The above is the entire content of today's open class. Thank you for your careful listening and cooperation."
Almost the second after Xu Yun finished his final summary, the bell rang to announce the end of the open class.
It can be said that the connection is very perfect.
Although everyone still had some unfinished thoughts, they had no choice but to gradually get up and leave the classroom with regret.
However, some bold students rushed directly to the podium and actively asked for autographs and photos.
"Classmate Xu Yun, can you sign your name for me?"
"I want to take a picture."
"When will there be another open class? The abstract algebra lecture today was really good."
"It's really strange to say that I heard other professors teach abstract algebra but couldn't understand it, but today I actually feel like I understand it."
"As expected of Xu Shen, what you said is really good."
Initially, everyone subconsciously wanted to call Xu Yun "teacher" when they first came up, but then they thought about the fact that the other person was an undergraduate like themselves, so they quickly changed it to "Classmate Xu Yun".
Faced with such enthusiastic classmates, Xu Yun didn't mind anything and basically complied with everyone's requests.
Qian Yudong, who was standing at the bottom, looked at Xu Yun who was surrounded by everyone on the podium and his face was filled with relief.
"As expected of someone who came out of our dormitory, he did not embarrass the dormitory and me, the dormitory leader."
After saying that, he didn't forget to turn around and look at Zhou Qi and Zhao Yuefeng behind him.
"You two should also learn from Xu Yun, but you must not hold us back in the dormitory."
"Strive for three kings."
Hearing that there were only three kings, Zhao Yuefeng looked suspicious and asked Qian Yudong casually.
"What about you?"
"Of course I can be a bronze with peace of mind. The three kings can take me flying no matter what." Qian Yudong raised his head and answered openly.
Immediately, Zhao Yuefeng and Zhou Qi rolled their eyes.
"We despise you."
Qin Xiangxin, Tang Yanshan and He Antai seemed to have something else to say to Xu Yun. After the open class, they did not leave immediately. Instead, they continued to sit in their original positions and wait until there were not many people on the podium. Just got up.
"This open class was really great. I wonder if you have any plans to stay in school in the future?"
Qin Xiangxin stopped next to Xu Yun. While highly praising his performance in class, he asked another question.
After listening to this open class, he had new plans for Xu Yun.
Since Xu Yun wants to continue studying and does not have time to teach regularly, let him be tied to the school first, and he can stay in the school to teach directly after he graduates.
Xu Yun had not thought about his plans after graduation for the time being, but suddenly heard Qin Xiangxin's words and did not answer immediately.
While he was thinking, He Antai's voice suddenly sounded in his ears.
"Dean Qin, you can consider this proposal carefully. Maybe he will become the youngest professor at Beijing University in the future."
"I will consider it carefully." Xu Yun nodded and answered.
"You don't need to feel any psychological pressure. Anyway, if you study for a Ph.D., it's still early for graduation." Qin Xiangxin noticed Xu Yun's expression, raised his hand, explained with a smile, and added: "Whenever you decide, come to me directly. That’s it.”
At this time, Tang Yanshan, who was next to him, couldn't help but couldn't help but couldn't help but take the initiative to join in the conversation.
"Xu Yun."
"Your lecturing talent is getting stronger and stronger."
"To be honest, even I am a little envious."
What he said is indeed correct. For a teacher, students can easily understand and grasp what he is talking about. This is the greatest affirmation of his teaching level.
Xu Yun naturally understands what Tang Yanshan means. As his abilities have greatly improved, he can analyze the problem very simply to get its core essence and summarize the rules. Once students know this rule, it will naturally become easier for them to learn. easy.
I can imagine that after he completes his graduation thesis, he will receive advanced task rewards, which will improve his abilities again.
This capability advantage will further increase.
If you look at it this way, if you become a professor in the future, it would be a waste not to have a few students.
"Maybe it's because my understanding of mathematics has deepened that I know better how to talk about a certain problem."
"That should be the reason." Tang Yanshan agreed with Xu Yun's answer, nodded and changed the topic to another matter: "How is your undergraduate thesis going?"
"We have a direction now. I will ask Professor Tang for advice after I finish the first draft." Xu Yun answered truthfully.
But as soon as he finished speaking, he saw Tang Yanshan waving his hands quickly.
"You can just set a date for the defense after the thesis is completed. I'm not necessarily higher than you in terms of the level of the thesis."
Naturally, Tang Yanshan would not supervise Xu Yun's thesis. In his opinion, Xu Yun's graduation thesis must be related to the Hodge conjecture. After all, as a world mathematical problem, it can be published to core journals if it is extended to any extent. He probably wouldn't even have supervised it, let alone supervised it. You may not be able to fully understand it.
Therefore, in order to avoid this embarrassing situation, it is the best way to let Xu Yun write his graduation thesis.
When Qin Xiangxin heard about the graduation defense, a mysterious smile suddenly appeared on his face.
I specifically reminded Xu Yun.
"In order to allow you to successfully complete your defense, I have already said hello to the Mathematical Society."
"Ten well-known domestic mathematics professors will be organized at that time to form the most authoritative defense committee. You must perform well and make sure you don't fail to graduate in the end."
Hearing this, Xu Yun's expression froze, and he felt confused about whether to laugh or cry.
"Dean."
"Isn't this lineup a bit too high?"
"It's just my undergraduate graduation defense."
"How else can we show that Peking University attaches great importance to you? Our country's mathematics development will still count on you in the future." Qin Xiangxin reached out and patted Xu Yun's shoulder and said sincerely.
Thanks to Qiankunju for the 100-point reward!
