Chapter 39 I, a junior, give lectures to the whole college!

That afternoon, we were in a small conference room on the top floor of the aircraft department building.

A total of more than a dozen teachers and students from Academician Du Yishan's research group were sitting around the oval conference table, watching Yao Mengna drawing pictures on the blackboard while talking about her research content this semester.

Regardless of whether you have a master's degree or a doctorate, one thing that every graduate student cannot escape is——

Group meeting.

Because scientific research has a long cycle and there is no regular standardized evaluation like exams, the instructor needs to keep track of the progress of his graduate students through regular reports.

Of course, this also means giving some pressure, asking graduate students to come up with something every once in a while, and not to overdo it, otherwise it will be difficult to end up not being able to graduate.

But in the final analysis, group meetings are still informal communication within the research group, and the frequency and form depend on the instructor.

Du Yishan's research group, or Du Yishan himself, does not like to hold group meetings. He usually prefers to let each student report individually.

In addition, the postgraduate students in the group generally have a more proactive attitude toward scientific research, so the frequency of group meetings is basically only once at the end of each semester.

According to past habits, after this group meeting, graduate students who have no important projects during the summer vacation can go home for the holidays.

So the atmosphere in the conference room is generally relatively relaxed and cheerful now.

"...The above is the main work I have done this semester. I would also like to thank Dr. Fang Zhen and Junior Brother Chang Haonan who helped me during the research process..."

As Yao Mengna's report was completed, there was a burst of warm applause in the conference room.

Generally speaking, undergraduate students and first-year master's students who are completing their projects do not need to speak in group meetings.

So as usual, the group meeting would basically end here.

But this time, there's a second half.

"Cough-cough-"

Du Yishan cleared his throat:

"Well, students, the first half of our group meeting is over. You can take a break for fifteen minutes. When you come back, let Chang Haonan demonstrate how to carry out efficient and accurate computer simulation and auxiliary design through practical examples. .”

As his words fell, everyone in the conference room stood up one after another, preparing to move their bodies, or go out to use the toilet or something.

But when Xia Tian opened the door first, the scene outside was so frightening that she subconsciously took two steps back and almost fell to the ground——

There was a large group of people darkly surrounding the door, roughly estimated to be twenty or thirty people, and some of them were very old, and they were obviously teachers.

"This is……"

Others in the conference room also noticed something strange outside.

At this time, a familiar figure from Chang Haonan quickly entered the conference room from outside.

It's Liu Hongbo.

"Xiao Liu? You...what's going on outside?"

Du Yishan was a little confused about the situation for a while.

"Uh...Teacher Du, that's it."

Liu Hongbo raised his arm to wipe the sweat from his forehead, and then explained:

"I heard from Junior Brother Fang Zhen yesterday that there will be a small lecture on computer simulation in the second half of your group meeting today, so I thought about bringing a few students over to listen together. But while waiting outside, I met a few other teachers, and when they found out about it, they all went back and called a few of their students, and just like that... it spread."

At this time, another teacher from outside the door also poked his head in:

"Academician Du, we..."

But he stopped mid-sentence, because the small classroom in front of him obviously couldn't accommodate the large group of people outside.

But if I were to say that I was just going back, I would still be a bit unwilling to do so.

After all, it was Academician Du who hired him, so his level must not be bad.

"Forget it, Xiao Liu, you go contact the dean and tell him that I want to organize a temporary meeting of several research groups from the Department of Aircraft and borrow the newly built multimedia classroom."

Du Yishan didn't mean to hide anything, but the current scale has indeed far exceeded his initial expectations.

……

About twenty minutes later, the group moved to the multimedia classroom in the next building.

Mainly because there is an LCD projector that was not very common in 1996, the kind that can be directly connected to a computer.

And the huge crowd attracted more teachers along the way.

Among them was even Tang Lintian, the dean of the School of Aeronautical Science and Engineering. After personally delivering the key, he did not go back directly, but followed him to find a seat to sit down.

In short, when Chang Haonan sat on the podium with his laptop in his arms, the classroom in front of him, which could accommodate almost 200 people, was already more than half full.

When Du Yishan agreed to give a demonstration the afternoon before yesterday, his mentality was still "it's just a group meeting, what kind of scene have I not seen before?".

but now……

I have never seen this scene before.

Although he had led many interns before his rebirth, he had never given lectures on such a large occasion. There were quite a few professors in the college below.

So to say I'm not nervous at all would be a lie.

But Chang Haonan also knew that he would have to face this kind of situation sooner or later in the future.

And the level will be even higher.

So there’s nothing wrong with exercising in advance.

Thinking of this, he felt a lot calmer.

Du Yishan, standing next to the podium, noticed Chang Haonan's nervousness at the beginning.

But just as he was about to go up and comfort him, he found that the latter had already adjusted himself, so he just sighed secretly in his heart, and then picked up the microphone next to him.

"Everyone who is here to listen, please find your seat as soon as possible. The second half of our group meeting will begin soon."

The academician spoke, and the effect was immediate, and the whispers below quickly disappeared.

But most people still looked at Chang Haonan with curiosity or suspicion.

Although most people had guessed before arriving that it was impossible for Du Yishan himself to give the lecture, the general estimate was that he had invited experts from outside.

And Chang Haonan's face...

Too young.

He even looks younger than most of the graduate students here.

"Good afternoon, teachers, and fellow seniors. According to Teacher Du's arrangement, I will briefly share with you some knowledge of computational fluid dynamics and its application in solving engineering problems."

This first sentence clearly confirmed his status as a student, and since everyone is called senior brother and senior sister, they must not be senior graduate students.

Tang Lintian, who had just opened his notebook, frowned slightly for a moment, and then showed a dumb smile.

Du Yishan would definitely not make a joke casually, so he judged that there were some deviations in the spread of the news by word of mouth.

"It should just be a study progress report, but it was misrepresented as a lecture..."

Thinking of this, Tang Lintian closed the notebook in front of him again.

Of course, the academician's face still had to be given, so he didn't leave midway and was still prepared to listen carefully.

"Before talking about practical applications, I have to talk about some basic theories..."

Contrary to most people's expectations, Chang Haonan did not directly start demonstrating the modeling and calculation process on the computer. Instead, he picked up a piece of chalk and walked to the blackboard.
