Chapter 798 My Big Boss Mentor.jpg

After all, the two are old classmates and haven't seen each other for nearly a year. Therefore, after talking about business, they are bound to brag about it.

Compared with Chang Haonan, who spends most of his time immersed in projects or experiments, Lao Wu's life is obviously more exciting and colorful.

The second half of the whole dinner was basically Chang Haonan listening to him telling stories alone.

Especially the few months he spent in the Balkans, the excitement was almost enough to write a novel.

Wu Yifan likes to drink.

But when he was abroad, he was worried about talking nonsense after drinking, so he always showed himself as a teetotaler.

Now that he has returned to China, he can finally drink freely.

So, although Chang Haonan didn't drink, he still got a little drunk by himself.

"Do you have any contact with the local US military?"

When Old Wu talked about how he wholesaled MRE and other logistical supplies from the US military at a low price, then sold them to Ermao for money, and finally made a 50% profit with the US military manager, Chang Haonan finally couldn't hold it anymore.

He knew that the US military was more flexible in making money.

But he had just arrived at the base and hadn't even sat down yet, and he dared to do business with a suspected Russian profiteer who came from an unknown source, which was a bit beyond his expectations.

"More than just contact..."

Old Wu swallowed another mouthful of Mao:

"The brigade commander of their camp is a... colonel, named... Martin Dempsey, and I talked to him... and laughed and laughed..."

At this time, his tone of speech had become increasingly incoherent.

But even the other party's rank and name were mentioned with details, which obviously made it credible.

And more importantly, Chang Haonan had heard of this name.

"No, wait a minute..."

He quickly stopped the other party from continuing:

"Are you sure your name is Martin Dempsey?"

"Yes... I think he was a regiment commander before."

Wu Yifan nodded, then suddenly stopped:

"Well... Organizational discipline should not... apply to a businessman like me... right?"

Actually, it can.

However, the nature of Lao Wu's business is special, and he really can't stick to these.

Chang Haonan waved his hand:

"Try to keep a relationship with him, maybe it will be useful in the future..."

Martin Dempsey, later served as Chairman of the US Joint Chiefs of Staff.

Of course, this is not important.

After all, that was almost 20 years later.

The point is that in Chang Haonan's impression, this man seemed to have risen to prominence in the Middle East after 2003 by relying on military merits.

So, this relationship is likely to come in handy...

...

In this way, the two of them had a meal until late at night.

Fortunately, Chang Haonan was very energetic, and since neither professors nor chief planners had to clock in, he was able to go to work as usual the next day.

Since he had been on a business trip in Shengjing for more than a week, when Chang Haonan returned to his office in Beijing Airlines, he found that there were already a lot of work on his desk that needed to be handled personally.

"Feasibility assessment of two boil-off gas reliquefaction system design schemes..."

"Structural risk assessment of the vibration of the transmission system of a super-large ship and its impact on the side wall of a thin-walled liquid cargo tank..."

"Diagnosis of early failures of large machinery based on the fusion of manifold learning algorithms..."

"..."

The top few were project reports or project applications submitted by three other teachers in the laboratory.

Fortunately, the length of the articles was not long, and they were all areas that Chang Haonan was familiar with, so it didn't take him much time to finish reading them all.

Liu Fangping and Lei Zhixing were indeed capable. After receiving the excessive funds from Chang Haonan, they did not focus all their energy on the feasibility study, but simultaneously carried out the second study mentioned above.

Because according to their investigation, the processing and manufacturing capabilities of Hudong Factory, or the entire Chinese shipbuilding industry, are still somewhat behind the world's first-class level.

And for large ships like LNG ships that work under extreme temperature differences, this gap is likely to bring additional risks...

Furthermore, although they did not mention it, Chang Haonan soon realized that this research result seems to be applicable to other fields.

For example, controlling submarine noise...

In short, although the budget allocated before was not left, others have completed double the task after all.

So it was not wasted.

They also passed the "test" set by Chang Haonan.

And the third item was naturally submitted by Yao Mengna.

She plans to open a topic with this as the research direction.

It's a coincidence.

Yao Mengna has not directly contacted the LNG ship project.

But this project that uses manifold learning algorithms for in-situ state monitoring and fault diagnosis seems to be able to solve the problems raised by Liu Fangping and Lei Zhixing...

In the end, he signed and approved it.

And under these three documents...

"Laboratory access permit?"

Chang Haonan was stunned when he saw the list in front of him.

Then he remembered that he had accepted a senior student from the school for postgraduate study.

And if you calculate the time, the recommended student should enter the laboratory...

Thinking of this, he broke out in a cold sweat.

He was obsessed with the project before and almost forgot about it.

If he came back from Shengjing a few days later, I'm afraid it would delay the student's graduation project...

So while condemning himself in his heart, he quickly contacted Li Yabo's counselor and asked him to notify him that he could come to his office.

"Alas..."

Chang Haonan hung up the phone and sighed softly:

"I'm still not used to it... I'm going to be a teacher..."

He pressed the power button of the computer, waited for a few minutes, and entered the mailbox as usual.

By 1999, many foreign companies had begun to send advertisements to the mailbox.

Especially since Chang Haonan had registered accounts with many publishers in order to upload papers, the top of the list was almost all filled with these meaningless contents.

Just when Chang Haonan was about to delete them all, a slightly inconspicuous email hidden in the middle caught his eye.

Judging from the sender's suffix, it seemed to be an email from a research institute.

This stopped his right hand from reaching for the delete key on the keyboard.

Then he opened the email.

The content was written in English.

The sentence structure was a bit strange.

But fortunately, it was still understandable.

[Dear Professor Chang Haonan, I accidentally saw your paper on Ricci flow surgery tools published in the Annals of Mathematics today, which inspired me a lot. Your research results have important driving significance for the entire field of differential geometry, especially the proof of the Poincare conjecture under low-dimensional conditions...]

The first part was a routine short greeting.

However, what Chang Haonan never expected was that.

The second part went straight into the hardcore part.

【Based on the results of your paper, I came to the following conclusion: Let g(ij) be a complete manifold on M, and satisfy g(ij)/γ=2R(ij), and M has bounded curvature...】

【……】

【I would like to ask, based on the above proof process, can we deduce that there is a non-negative curvature operator and bounded curvature on (-∞, T] (T>0), and it is k-noncollapsed on all scales?】

The jumps in the content of the email made it difficult for Chang Haonan to follow the train of thought.

But I finally understood it.

The other party proposed a reduced volume algorithm on Ricci flow and tried to use this algorithm to prove Two non-local collapse theorems are used to estimate the local injection radius of compact manifolds.

As for the identity of the sender...

In fact, it is almost obvious.

There are only a few people in the world who would directly send such top-level results to communicate via email.

And then limit it to the field of differential geometry...

Chang Haonan gently rolled the mouse wheel.

It was just as he expected.

The signature at the bottom of the email is Перельман Григорий Яковлевич.

Perelman Grigory Yakovlevich.

That is, the super-human who turned the Poincaré conjecture into the Poincaré-Perelman theorem in the previous timeline. Great guy.

Moreover, after reading this email, Chang Haonan finally understood why it took three years for his proof to be widely recognized by the mathematics community.

Too much jump.

Even though the other party's starting point was Chang's lemma proved by Chang Haonan, even though the email mentioned only a small step in the proof of the Poincare conjecture, even though the email was already quite long...

But Chang Haonan still spent almost a whole morning to fully understand it.

It is conceivable that the mathematicians in the previous life were so confused when they saw the proof process thrown out by the other party without any prior preparation...

Slightly sorted out his thoughts After that, Chang Haonan clicked the "Reply" option and prepared to write a reply to the other party.

At this moment, there was a knock on the door outside the office.

Chang Haonan stopped.

The computer in his office was connected to the external network, and it was impossible to process confidential information on it, so there was no saying that he could not see anyone.

"Please come in!"

The person who came was Li Yabo, whom he had just called over.

"Teacher Chang, I heard from the counselor that you were looking for me."

"Yes, it's about your graduation project."

Chang Haonan raised his hand to signal the other party to sit on the chair opposite.

"Uh..."

Li Yabo pursed his lips, as if he was really hesitant about whether to speak.

But in the end he said:

"I looked at the list of topics provided by the college before, and it seems that you didn't submit your graduation project, Professor Chang?"

Awkward.

Very embarrassing.

In fact, Chang Haonan did forget.

Or, as a new professor, he didn't even know there was such a thing as "submitting graduation project".

Of course, it was impossible to admit such a shameful thing in front of his students.

And considering the relationship between him and Tang Lintian, this was not necessarily a big deal.

So, Chang Haonan replied calmly:

"Yes, because I'm going to let you think about it yourself, which specific direction and field you want to do research related to, and then apply for it."

Now it was Li Yabo's turn to be confused:

"Ah?"

"I...but..."

"You should at least give me a basic range, right?"

Chang Haonan smiled slightly:

"No, as long as you are interested, have the relevant basic knowledge, and are able to proceed, it's all right."

"Even if I don't have it on hand, I can find a topic for you!"

Li Yabo directly retreated tactically, thinking that this is the benefit of following a big mentor?

However, after a brief surprise, he quickly gave his answer:

"Teacher Chang, I want to study the mechanical analysis and design of large-diameter thin-walled box structures of composite materials!"
