Chapter 798 My Big Boss Mentorjpg
After all, the two are old classmates, and they haven't seen each other for nearly a year. Therefore, after the serious chat, a routine bragging session is inevitable.
Compared to Chang Haonan, who spends most of his time immersed in projects or experiments, Lao Wu's life is obviously much more exciting and colorful.
Throughout the second half of the meal, Chang Haonan was basically listening to him telling stories alone.
Especially the few months I spent in the Balkans were so exciting that I could almost write a novel.
Wu Yifan prefers drinking.
But when I was abroad, I was worried about making a mistake after drinking, so I always presented myself as a teetotaler.
Now that I'm back in China, I can finally drink freely.
Therefore, although Chang Haonan did not drink, he still got a little drunk by himself.
"Do you still have contact with the local US military?"
When Lao Wu talked about how he wholesaled MRE and other logistical supplies from the US military at low prices, then sold them to Ermao for money, and finally got involved with Eryi Tian, who was in charge of the US military, Chang Haonan finally couldn't hold himself back. .
The US military has more flexible ways of making money, and he knows this.
However, it was a bit beyond his expectation that he would dare to do business with a suspected Russian businessman of unknown origin before he even had time to sit down at the base.
"More than just contact..."
Old Wu took another mouthful of thatch:
"The brigade commander in their camp over there is a... colonel, his name is... what's his name? Martin Dempsey. I talked... and laughed..."
At this time, his tone of voice had become increasingly incoherent.
But even the military rank and name of the other party are mentioned clearly, so it is obviously credible.
And more importantly, Chang Haonan has heard of this name.
"It's not you who wait a moment..."
He quickly stopped the other party from continuing:
"Are you sure your name is Martin Dempsey?"
"Yeah...it seems that he was a group leader before."
Wu Yifan nodded, then suddenly stopped:
"Then...organizational discipline shouldn't...can't control me as a business person...right?"
In fact, it is possible.
However, Lao Wu's business is of a special nature and he really cannot stick to this.
Chang Haonan waved his hand:
"Try to maintain a relationship with him, maybe it will be useful in the future..."
Martin Dempsey, later Chairman of the Joint Chiefs of Staff of the United States.
Of course, this doesn't really matter.
After all, that was almost 20 years later.
The point is that in Chang Haonan's impression, this man seems to have risen to great heights in the Middle East by relying on military exploits after 2003.
Therefore, there is a high probability that this relationship will really come in handy...
……
In this way, the meal between the two of them lasted until late at night.
Fortunately, Chang Haonan was very energetic, and neither the professor nor the chief planner had to check in, so he could still 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 was already a lot of work piled on the table that needed to be handled by him personally.
"Feasibility evaluation of two boil-off gas reliquefaction system design options..."
"Vibration of ultra-large ship's transmission system and its structural risk assessment on the side walls of thin-walled cargo tanks..."
"Fusion diagnosis of early faults of large machinery based on manifold learning algorithm..."
"..."
The top few are project reports or project applications submitted by three other teachers in the laboratory.
Fortunately, the chapters are not too long, and they are all areas that Chang Haonan is relatively familiar with, so it didn't take much time to read them all.
Liu Fangping and Lei Zhixing were indeed capable. After receiving the excessive funding from Chang Haonan, they did not focus all their energy on the feasibility study, but simultaneously carried out the second project mentioned above. Research.
Because according to their inspection, there is indeed a certain gap between the processing and manufacturing capabilities of the Hudong Plant, or the entire Chinese shipbuilding industry, and the world's first-class levels.
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 quickly realized that this research result seemed to be applicable to other fields.
For example, controlling submarine noise and so on...
In short, although the budget allocated previously was not left, others completed double the amount of tasks.
So it's not wasted.
They can be regarded as passing the "test" set by Chang Haonan.
The third item was naturally submitted by Yao Mengna.
She plans to set up a topic on this as a research direction.
Coincidentally.
Yao Mengna has not had direct contact with the LNG ship project.
But this project, which uses manifold learning algorithms for in-situ condition monitoring and fault diagnosis, seems to be able to solve the problems raised by Liu Fangping and Lei Zhixing...
In the end, it was naturally signed and approved.
And below these three contents...
"Laboratory access permission?"
Chang Haonan was stunned when he looked at the list in front of him.
Then I remembered that I had previously accepted a senior student from my school for graduate school.
And if we calculate the time, it is indeed time for recommended students to enter the laboratory...
Thinking of this, he suddenly broke into a cold sweat.
I was so obsessed with the project that I almost forgot about it.
If I come back from Shengjing a few days later, I'm afraid it will delay the students' graduation projects...
So while reprimanding myself a few words in my heart, I quickly contacted Li Yabo's counselor and asked the other party to inform him that I could come to his office.
"Ugh……"
Chang Hao hung up the phone and sighed softly:
"I still can't get used to it... I'm going to be a teacher now..."
As he spoke, he pressed the power button of the computer, waited for a few minutes, and then entered the mailbox as usual.
By this time in 1999, many foreign companies had begun to send advertisements to mailboxes.
In particular, Chang Haonan had previously registered accounts for many publishing houses in order to upload papers, so the top ones were almost all filled with content that was not nutritious.
Just when Chang Haonan was about to frame them together and delete them all, a slightly inconspicuous email hidden in the middle came into his sight.
Judging from the sender's suffix, it seems to be the email address of a research institution.
This stopped him from reaching for the delete key on the keyboard with his right hand.
Then opened this email.
The content is written in English.
The sentence structure is a bit strange.
But fortunately, I can still understand it.
[Dear Professor Chang Haonan, today I happened to see your paper published in the Annals of Mathematics on the mathematical tools of Ricci flow, 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...]
It is preceded by a routine brief greeting.
However, what Chang Haonan never expected was.
Then we went directly to 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 on (-∞, T] (T>0), there is a non-negative curvature operator and bounded curvature, and it is k-noncollapsed on all scales?]
The jumping content of the email made it difficult for Chang Haonan to keep up.
But I finally understood it.
The other party proposed a volume reduction algorithm based on Ricci flow, and tried to use this algorithm to prove two non-local collapse theorems, which are used to estimate the local injective radius of compact manifolds.
As for the identity of the sender…
In fact, it’s almost ready to come out.
There are only a few people in the world who would send such top-level results directly via email for communication.
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 ПepeльmahГpnгopnnrkoвлeвnч.
Perelman Grigory Yakovlevich.
That is, the super master who turned the Poincaré conjecture into the Poincaré-Perelman theorem in the previous timeline.
Moreover, after reading this email, Chang Haonan finally understood why it took three years for his proof process to be widely recognized by the mathematics community——
What a jump.
Even if the other party's starting point is Chang's Lemma proved by Chang Haonan, even if what is mentioned in the email is still only a small step in the process of proving the Poincaré Conjecture, even if the length of the email is already quite long...
But it still took Chang Haonan almost a whole morning to fully understand it.
One can imagine how confused the mathematicians in the previous life were when they directly saw the proof process thrown out by the other party without any preparation...
After sorting out his thoughts for a while, 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 is connected to the Internet, and it is impossible to process confidential information on it, so there is no reason why he cannot see people.
"Please come in!"
The person who came was none other than Li Yabo who he had just called over.
"Teacher Chang, I heard the counselor said you were looking for me."
"Yes, it's about your completion."
Chang Haonan raised his hand and motioned for the other person to sit on the chair opposite.
"Uh……"
Li Yabo pursed his lips, seeming really hesitant to speak.
But in the end he said:
"I looked at the list of topics provided by the college before. Teacher Chang, it seems that you didn't submit a final topic?"
awkward.
Very embarrassing.
In fact, Chang Haonan had indeed forgotten.
In other words, as a new professor, he didn't even know that there was such a thing as "submitting a graduation project."
Of course, it was impossible to admit such an embarrassing thing in front of his own students.
And considering the relationship between him and Tang Lintian, this may not be a big deal.
So, Chang Haonan replied without changing his expression or heartbeat:
"Yes, because I'm going to let you think about the specific direction and field of research you want to do, and then apply for it."
This time it was Li Yabo's turn to be confused:
"what?"
"I...but..."
"You should at least give me a basic range, right?"
Chang Haonan smiled slightly:
"No, as long as you are interested, have relevant basic knowledge, and have the ability to proceed, you can do it."
"Even if I don't have it on hand, I can still find a topic for you!"
Li Yabo was just a tactical supporter. Is this the benefit of following a big boss mentor?
However, after being briefly surprised, he quickly gave his answer:
"Teacher Chang, I want to study the mechanical analysis and design of large-diameter thin-walled box structures made of composite materials!"
