Chapter 737 Graduation defense with outrageous lineup (page 12)

Chang Haonan's defense meeting was not arranged within Beijing Hang University.

Instead, they directly found a conference room in Torch Group for the meeting.

Because what is going to happen in a while is far more than just a thesis defense.

Defending a doctorate for the general manager of another company on someone else's territory is probably relatively rare even in the degree-granting process around the world.

But compared with Chang Haonan's own situation, it doesn't seem that rare...

"Xiao Chang, long time no see."

Tang Lintian, who had been promoted to acting principal at a speed close to the triple jump, stopped Chang Haonan at the door of the building:

"After today, I won't have the chance to call you that again."

"Principal Tang, I just graduated. There will still be opportunities to meet in the future..."

Chang Haonan turned his head and saw three other people behind him.

Du Yishan and Liu Zhenxiang are naturally among them.

But the person standing at the end is an unfamiliar face. He should be a teacher from a foreign school invited here according to the requirements of the review mechanism.

As for Fang Zhen, who was a review expert during Chang Haonan's undergraduate defense...

Considering that he currently works in the Torch Group and is considered a subordinate of the former, according to the principle of avoidance, it is impossible to participate in any case.

Perhaps seeing Chang Haonan's slightly confused look, Du Yishan motioned to everyone to make room for that person, and then introduced:

"Xiao Chang, this is Professor Yuan Xiangya, the deputy dean of the Institute of Mathematics and Systems Science of the Chinese Academy of Sciences."

Hearing this name, Chang Haonan suddenly understood.

Although the other party's face was relatively unfamiliar, Chang Haonan had heard of Yuan Xiangya's name.

In fact, if you want to study the theory of nonlinear programming algorithms, it is basically impossible to avoid him.

1985年，25岁的袁相垭在攻读博士期间与他人共同证明了截断共轭梯度法的“1/2猜想”，算是整个80年代非线性规划算法理论重要的成果之一。

In addition, he also systematically proposed a series of new algorithms using a combination of trust region methods and traditional line search methods to solve nonlinear planning problems.

Some people have even begun to call this series of results "Yuan's Lemma".

Although this term has not yet been widely accepted, judging from the current momentum, it will be a matter of time.

Although a lemma in a non-explicit field of science is definitely not as influential and status as those famous theorems, there is no doubt that being able to put one's name on it is definitely considered to be a leader in the field of applied mathematics. peak.

In short, he is also a player who is comparable to cheating.

Chang Haonan took two steps forward and shook hands with the other party:

"Professor Yuan, I am honored that you can come to participate in my graduation defense. Your research methods and results have inspired me a lot during my previous research."

Yuan Xiangya is less than forty years old this year. Standing among several people, he is closer to Chang Haonan's age.

“Learn from each other, learn from each other.”

The other party smiled modestly:

"The TORCH Multiphysics software, and of course the algorithms behind the software, can be said to be the greatest achievement in the field of computational mathematics at the application level in recent years."

"If nothing else, those of us who are engaged in applied mathematics can speak very forcefully when we go to meetings now..."

Although this statement is a bit exaggerated, the atmosphere in the corridor became relaxed because of it.

"Actually, if your defense is held in public, I will definitely ask half of my students to come and participate."

"Not all of them?"

Du Yishan, who was standing next to him, interrupted and asked jokingly.

But Yuan Xiangya shook his head very solemnly:

"Not all, because the other half won't understand even if they come over, so there's no need to waste time. It's better to leave the position to those who need it more..."

After saying this, even Chang Haonan himself almost burst out laughing.

But considering that I was still a student today, I finally held back.

After some pleasantries, Chang Haonan was ready to take everyone upstairs.

It was only then that he suddenly realized that there were only four people here.

"Teacher Du, the graduation review should have at least five review members. Are we... still missing one?"

"Don't worry, we're almost there."

Du Yishan raised his wrist and looked at his watch:

"The old man is relatively old, so he was picked up by a special car, so he didn't come with us."

"I'm older..."

You must know that Du Yishan is already 70 years old. The only people he can say are old are those from the early founding generation of the People's Republic of China...

Just when he started to guess who the visitor might be, he saw a minibus slowly driving into the company compound from the direction of the gate, then making a half circle and driving straight from the side vehicle ramp to where he was waiting. in front of several people.

When the car door opened, the first people to get out were naturally a few staff members.

But soon, a gray-haired old man wearing a Chinese tunic suit appeared at the door of the car.

?

Chang Haonan was stunned for a moment.

No introduction is needed at all.

He's been seen countless times on television and in the media.

"Mr. Qian..."

Several people rushed to greet him.

In front of this master of aerodynamics in applied mechanics and the founder of engineering cybernetics, no matter whether he is in his seventies, thirty or twenty, he is still a junior.

After shaking hands one by one, Mr. Qian finally came to Chang Haonan:

"A few years ago, I heard the junior students at the Academy of Sciences talking about you. This time I saw your true form."

Although he is already 90 years old, Mr. Qian still speaks and thinks relatively smoothly, and his physique does not appear too old.

"Xiao Chang, Mr. Qian took the initiative to apply to be the chairman of your defense committee this time."

After Mr. Qian finished speaking, Du Yishan added next to him.

"Thank you Mr. Qian!"

In this situation, Chang Haonan really has nothing else to say:

"It's a bit windy outside, let's go in and chat first..."

In fact, the composition of Chang Haonan's defense committee is already obvious.

The so-called review is mainly to examine whether the research results that match the requirements of a "doctoral degree" have been produced during the degree study.

But this is for ordinary people.

The achievements of Chang Haonan during his Ph.D. studies have been placed in factories or flown to the sky, and there is no need to express them in papers.

Therefore, the focus of this defense committee is not on the defense itself, but on the fact that the members must have enough influence——

Not everyone is qualified to award Chang Haonan a degree.

If an ordinary PhD supervisor came and signed Chang Haonan's review opinion, wouldn't his hands be shaking?

Moreover, the lineup is not enough.

As for the current lineup, Du Yishan and Qian Lao, two academicians of both academies, Liu Zhenxiang, the first academician in the aviation power industry, Tang Lintian, the president of Beijing Airlines, who is probably not far away from being an academician, and one of the top young scholars in the field of applied mathematics in China, who is also not far away from being an academician. Yuan Xiangya, who is barely qualified...
