Junxin, who took over the tasks assigned by Professor Wang, has become very busy during this period of time, busy preparing for classes, busy teaching, busy writing textbook outlines, busy organizing afternoon tea salon activities, and also busy communicating and learning with professors.

The days are full, and time slips away unconsciously. Fortunately, what makes Junxin happy is that under the guidance of Junxin, the group of students who have been educated have begun to slowly build up their self-confidence and begin to have a simple communication with Junxin in class.

Before you know it, the Spring Festival is coming, and the first trial run of the afternoon tea salon carefully prepared by Junxin is about to begin. Since the holiday is approaching, the teachers have deliberately slowed down the pace of teaching and let the students start to prepare for this first exchange. Junxin wasted no time in handing over the topic of the first discussion to these students after a class of algebraic topology.

Since Professor Wang announced that he would hold such an exchange meeting, Junxin's actions have attracted the attention of all the students in Hua Luogeng's class. In their eyes, this may be an opportunity for them to complete their gorgeous transformation, be appreciated by the professors, become their graduate students, and then step up to the sky. And being able to get any bit of information is worthy of their attention, not to mention the words revealed by a host like Junxin.

For such a situation, Junxin can't say whether it's good or bad. It is a very good thing to be able to actively participate in the seminar, but at the same time, there is an indescribable meaning in Junxin for the purpose of participating in such a seminar.

However, the current situation of the country is like this, and Junxin can only maintain his own opinion, and try not to echo their ideas. In his eyes, this is not a formal discussion in the first place, but a relatively casual exchange, and there should be no such idea. It's just a few years after the **** just ended, how many people can be serious about learning? Junxin can only turn a blind eye and do his part.

Time flies, and in a blink of an eye, it is time for the first afternoon tea discussion organized by Junxin. Due to the support of Professor Wang and Professor Qiao, the location was placed in the conference room of the mathematics department, which was a little more upscale, although Junxin objected to putting it in that place, he would rather put it in the cafeteria. However, Professor Wang did not take his advice, and put it in the conference room a little stubbornly.

Sure enough, when Junxin entered the conference room, he felt that he seemed to have come to the venue of a more formal meeting, and he couldn't help but sigh, he felt an indescribable depression in his heart, he didn't want to turn the kind of afternoon tea-style discussion that was free to discuss into this kind of meeting-style discussion, because it had lost its original meaning.

"Jun, are you here?" Although Professor Wang said that he would not come to participate, this was the first event after all, and he thought it was necessary for him to come over to help Junxin Town.

Jun Xin looked at Professor Wang a little helplessly, and said, "Professor, are you here too?" ”

"After all, it's the first time, let's take a look!" Professor Wang didn't care about Junxin's eyes, and said with a smile, "What, have you prepared anything?" ”

Junxin shook his head and said, "Everything you prepare is in your own head, I just need to record some of the inspiration that comes from the discussion." ”

"Today is your home field, do it well!" Professor Wang smiled and patted Junxin on the shoulder, he didn't know that Junxin had a lot of opinions about his approach, but the events of the past ten years made a scientist like him who was full of firm belief in the pursuit of truth a little scared. Even if it has passed, it is full of jealousy and caution about such things.

Jun Xin nodded, he could somewhat understand Professor Wang's approach, otherwise, with his temper, Professor Wang's idea would have been vetoed by him on the basis of reason, where would there be any room for compromise?

After saying hello to Professor Wang, Junxin casually came to a position to do it, and next to him, several students were already writing and discussing a few questions left by Junxin.

Junxin has been teaching for three weeks now, during which a total of three questions have been left, each of which involves some cutting-edge issues, which is of great value for discussion. Because even now, none of them have been able to solve these three questions.

"Hehe, how's the discussion going?" Junxin suddenly interjected and asked with a smile.

"Hello teacher!" Several people hurriedly stood up and saluted, and one of them said, "We are discussing the topic that the teacher left over from last week." ”

"Sit!" After motioning for them to sit down, Jun Xin asked, "What's the catch?" ”

A boy dressed in black replied, "I am more interested in the topology problem left by the teacher, and I have consulted a lot of literature and found some achievements of my predecessors, but I still can't find the way." ”

"That question is actually far beyond your knowledge reserves, and it belongs to the cutting-edge problem." Jun Xin sighed first, and then began to answer some of the doubts raised by the student, and gave some suggestions, but he refused to say the idea of solving the problem.

A few people chatted, and the people around them quickly gathered, Professor Wang and several other professors had already left this place after seeing that everything was normal, and Junxin's age was close to them, so they also let go in front of Junxin.

When the discussion was over, the students on one side began to ask another question, and then one after another. Junxin gradually began to get impatient, originally planning to let them communicate, not to come out and give them questions and suggestions himself. Therefore, after answering a question about advanced number theory, Jun Xin decisively ended the question and answer, and asked very seriously: "Let's put the questions aside, there are some questions I want to ask you, what do you think mathematics can do?" Why study math? ”

As soon as Junxin's words came out, the audience was silent, and they didn't know why the teacher they admired so much suddenly asked such a question.

"Xiao Zhao, you talk about it first, don't care about my opinion, I just want to know what you really think." Xiao Zhao was the first to ask questions, and he was also the most potential person in the class that Junxin found.

Others are either interested in number theory or differential equations, and there is very little interest in geometry, which is an extremely abstract branch of the subject, and some are also because of the differential geometry spread by Professor Chern and Professor Su Buqing in China, while others such as fractal geometry, projective geometry, Riemannian geometry, non-Euclidean geometry and even algebraic geometry are not of interest to anyone, let alone topology, which is abstract to the extreme.

The boy named Zhao Zhen in front of him is different, he has an amazing talent for topology, and he himself has a strong interest in topology. However, Zhao Zhen, who was very interested in this, went headlong into it, and asked Junxin for a lot of bibliographies and studied it carefully. Junxin expects more from him than the others.
