Technology invades the modern world

Chapter 103 Is this the missing piece of the puzzle? (Monthly vote requested!)
In Yanjing, a Slav came to the building where the Fifth Academy was located.

This Slav is also an old acquaintance of President Qian, the designer of the P-2 missile, Pokrovsky.

"Qian, I have good news for you." Pokrovsky said with a smile, handing over a thick envelope.

Dean Qian doesn't believe that there are good Russians.

The Russians just recently forcibly bought their guidance technology.

"Туполев/Tupolev" Dean Qian took the envelope and looked at the surface carefully, and found that it was printed in Russian.

He didn't understand Russian, so he opened it and took a look. It was also a Russian document. "Sorry, I need to wait for the translation. I can reply to you after the translation."

Pokrovsky waved his hand. "No need to reply. This is a gift that Mr. Korolev had someone pass on to you."

Dean Qian combined the latest reports he saw in the internal news with the idea that Korolev had specially gone to London to meet Lin Ran.

He had some guesses about the document in front of him.

"Xiao Sun, come here quickly. There's a document here that needs your translation."

As soon as Pokrovsky left, Dean Qian rushed out of the office impatiently and went outside to look for Sun Jiadong.

Later, the father of China's satellite worked in the Fifth Academy at that time. In addition to his design work, he was also the best Russian translator in the entire Fifth Academy.

Because he studied at the Zhukovsky Air Force Engineering Academy for a full eight years.

"Dean Qian, what's the matter?" Sun Jiadong quickly came over and asked.

"Here is a document that you need to translate immediately!

It's urgent." Dean Qian handed him the envelope.

He took it and took a look at it: "This is the Tupolev Design Bureau's logo.

Dean, where did you get this document? The Tupolev Design Bureau is quite impressive; it's the Russian design bureau that specializes in bomber development.

Look at the OKB-156 on the lower right corner. This envelope must be quite old.

The predecessor of the Tupolev Design Bureau was called Experimental Design Bureau No. 156, hence the name OKB-156." Although Sun Jiadong had studied in the Soviet Union for eight years, he was only in his early thirties and still had the temperament of a young man.

“You kid, I know you’re an expert on the Soviet Union and Russia.

Okay, hurry up and translate it. This document is very important. You must translate it for me today!
Did you hear that? "

Sun Jiadong stood at attention and said seriously, "I guarantee that the mission will be completed!"

Dean Qian nodded, and then he went to Zhang Kewen, "Xiao Zhang, please prepare a car for me, I need to go to the Student Affairs Office.

Also, please help me and Director Su of the Institute of Mathematics of the Chinese Academy of Sciences organize a meeting with experts at the Academic Committee tomorrow morning."

Since Hua Luogeng was transferred to work in Guangzhou, Su Buqing, who was originally supposed to work at Fudan at that time, was transferred to the Institute of Mathematics of the Chinese Academy of Sciences.

In addition, he is engaged in research in differential geometry, and his mathematics is more suitable for application.

Zhang Guanghou, who works on partial differential equations and mathematical physics, was also protected.

学委
"Leader, Pokrovsky from the Soviet Union suddenly came to me today and said that Korolev wanted to pass on a document to me. After I opened it, I found that it was an academic paper.

He said it was a gift he was delivering for someone else.

Considering that Korolev had just met Bai Ma in London not long ago, I suspected that it was Bai Ma who wanted to pass on the information to us.

I have already arranged for someone to translate it, and after the translation, I hope to transfer colleagues from the Institute of Mathematics of the Chinese Academy of Sciences to translate it.

Considering Bai Ma's current identity and status, he would definitely not pass on academic papers to us for no reason.

Or through Korolev, this paper must be of extraordinary value."

That’s right, Lin Ran’s code name within China is White Horse.

It also takes the allusion of "a white horse is not a horse", and when translated into English, no one would guess that white horse is Fermat.

At the same time, horse and house are similar. White house refers to the White House, and the other party happens to be working in the White House at this time.

This code name has multiple meanings.

"I understand what you mean. The value of the white horse is indeed very great."

No one in China is talking about bringing him back.

But they don't even know the most basic way to connect with each other.

Chen Jingrun, who was sent to America under the pseudonym Chen Dehui, couldn't even see Lin Ran.

One is in New York and the other is in Washington.

Chen Jingrun lived in the world of mathematics and was very happy to communicate with masters in the field of number theory in New York every day.

But he never wore white clothes for a single day.

That’s right, there was a restaurant run by overseas Chinese outside the City University of New York, and Chen Jingrun would go there for breakfast every morning.

If he was wearing white clothes, it would mean that he had met Lin Ran the day before.

Then Chen Jingrun had to write a report on the content of the meeting and send it back.

And if he is not wearing it, it means nothing happened.

Chen Jingrun went to New York for half a year and only met Lin Ran once.

What's even worse is Section Chief Zhang, whose daily work is either sailing or unloading cargo at the dock. He finally gets to see his "son", but has no information. The two look at each other in silence in the restaurant because they are not real father and son.

Even Section Chief Zhang, whose skin was rough and several shades darker, felt like crying but had no tears when he looked at the fair and plump Chen Jingrun.

So for China, Lin Ran is a true X factor.

But they don't need to worry too much, because with the promotion of the hotline, opportunities will soon appear.

“But White Horse will pass it on to us through Korolev, which means Korolev will also read it.

So how can we ensure that what Korolev conveys to us is the original intention of the White Horse?

And after passing through Korolev's hands, is its value really that great?" The leader raised his doubts.

Dean Qian said: "In any case, we will know tomorrow."

"This is a paper related to cybernetics. It abstracts space problems into a mathematical model to solve them."

After Su Buqing finished his brief speech, he stood on the podium and continued:
“It’s a completely new approach, and I haven’t seen anything like it in academic papers.

The person who could write this paper must be a master.” Su Buqing said, “He must be much better than me.”

Dean Qian, who was listening in the audience, thought to himself that he was not only a master, but a master among masters.

After listening to it, he guessed where it could be used, but he still waited for Su Buqing to speak first.

"It can transform non-convex optimization problems into convex optimization, which is the most important breakthrough."

After Su Buqing finished speaking, President Qian continued:
“Simply put, traditional non-convex optimization methods may fall into local optimal solutions when dealing with complex constraints, while lossless convexification methods can transform these problems into convex problems, thereby obtaining global optimal solutions.

For example, the DF-2 we are going to develop, its flight trajectory and control system design.

The solutions we obtained in the past may only be optimal in a certain section in the middle, and may not be optimal when connected together.

Now we can transform it into a convex problem and find the optimal solution after combining the whole process.

Of course, the ability to convert does not mean that the global solution can be calculated.

But this method can be used for both the thrust distribution and flight path of the rocket."

After the meeting, Su Buqing said to Dean Qian in private, "Dean Qian, I didn't expect that there is someone in your team who is so knowledgeable about applied mathematics.

You guys at the Fifth Academy are full of talented people. This paper not only innovates at the intersection of optimal control theory and convex optimization, but also demonstrates computational feasibility through numerical analysis and provides theoretical support through geometric methods.

There are such people in applied mathematics in China. How come I haven’t heard of them before?”

Su Buqing is also a master figure, although you can say that his research scope is limited to projective geometry, which is just traditional differential geometry. He does not involve topology and has not participated in the construction of modern mathematics. He cannot be compared with people like Shiing-Shen Chern and Shing-Tung Yau.

But you also have to look at the conditions.

The contribution he made in the 1930s can definitely be regarded as one of the important advances in the field of differential geometry in the 1930s.

It also doesn't prevent him from having a sharp eye.

Dean Qian smiled bitterly and said, "Okay, stop asking."

Then he whispered, "I got this paper from Maozi with great difficulty."

Su Buqing immediately understood: "No wonder, the Maozi are really strong in this aspect.

The launch of satellites one after another made the Americans nervous.

We still have too few talented people in the field of mathematics, and we need to work harder."

Dean Qian sighed and said, "Yes, it would be great if the overseas Chinese mathematics masters could come back."

This time it was Su Buqing's turn to smile bitterly: "Are you talking about Chen Shengshen or Lin Ran?
Lin Ran has become a powerful figure in the White House. Even if he comes back, who would dare to use him?

All the Chinese math masters are in America, so forget it, let’s train them ourselves.”

Dean Qian shook his head: "Yes."

It's all about money, so Su Buqing dared to say that.

If it were someone else, he would definitely not mention it.

When reporting back to the Student Council that afternoon, Dean Qian said:
“The paper is very beautiful and a very impressive academic achievement. It is also very helpful to us.

It can play a certain role in improving missile accuracy and reliability, and can also play a role in the development of launch vehicles.

But it didn't meet my expectations.

I wonder if you understand?
I always feel that Bai Ma is putting so much effort into it.

This should be a once-in-a-lifetime opportunity for Korolev to meet him.

Next time, America would definitely raise security to the highest level, and it would be impossible for the Soviet Union to find another chance to get close to him.

So for such a rare opportunity, Baima only sent back such a paper.

It’s already very precious, but it’s not enough. I always feel like something is missing.

Maybe it was just like the time when Chen Jingrun gained a lot, but the last piece of the puzzle was what Bai Ma told him, all of which were related to missile trajectory optimization.

I always feel that this time must be the same as last time, or even more important.

However, because there is no way to contact Bai Ma directly, there is no way to obtain the crucial puzzle piece from Bai Ma.

That’s why there’s always a feeling of being almost there.”

Dean Qian paced around the secret office impatiently.

Trying to find the remaining pieces of the puzzle on my own.

"Okay, don't worry. If it's really important, we will think of it sooner or later." The other party persuaded.

Dean Qian patted his head and said, "No, this kind of thing must be done sooner rather than later.

I need to think about it.”

“Have you ever thought that there is another possibility, that he gave the puzzle piece.

He gave it to Korolev, but Korolev didn’t pass the puzzle on to us?”

Dean Qian said: "Of course I have thought about it, and it is very possible.

After all, our relationship is very tense, so it's normal for them to play tricks.

But I am sure that since Bai Ma dared to pass the news to us through Korolev, he must be sure that we can accurately understand his meaning. "

Dean Qian’s guess was correct, but it would be a long wait.

It was not until the success of America and the Soviet Union's reusable rockets that he found the last piece of the puzzle, combined with Lin Ran's interview with the New York Times.

"Mr. Xu, I'm sorry, the Americans are only willing to give us a seat on the International Shipping Standards Committee and a seat on the board of directors of the International Maritime Standards Company to be established later.

And all they can give me is that I failed to fulfill my promise to you.

But this does not affect me. I work at NASA and I don't have time to attend these occasions. When the time comes, I will authorize you or other Hong Kong shipowners to represent me.

Responsible for safeguarding the interests of Hong Kong shipping in these two areas."

After agreeing on a time via telegram, Lin Ran made a transatlantic call to Xu Aizhou.

Lin Ran’s calls to foreign countries will be recorded by a certain BI.

Lin Ran has been informed of this.

Although FISA did not exist at that time, there were communications laws and wartime legacy policies, so such recordings were allowed.

Because international long-distance calls need to be transmitted through submarine cables, they will be intercepted by dedicated personnel.

Feng Brian received similar treatment back then.

But not when calling someone in the US.

At least America told Lin Ran openly that she wouldn't do that.

"Okay, don't worry, I will do it properly.

I personally suggest that you give this position to Tung Chao-Yen and Pao Yue-Kong respectively.

You have met Dong Haoyun, and you understand the Dong family. He will definitely be able to do this job well.

The latter, Pao Yue-kong, was the only small merchant who survived the squeeze from Jardine Matheson this time, under the coercion and inducement of Ho Sin-hang, the founder of Hang Seng Bank.

He made the bold statement, "I want to be an upright Chinese, not a Chinese who serves as a dog for white people!"

He's trustworthy, younger, more motivated, and better at fighting for the interests of the Chinese," Xu Aizhou said slowly.

Both he and Tung Chao-Yen admired Pao Yue-Kong very much after this incident. In addition, the story of Ho Sin-Heng's humiliation was also widely spread.

After all, at that time, besides the two of them, there were also Pao Yue-kong's family and servants in Pao Yue-kong's home.

This matter soon spread to everyone in the Hong Kong business community.

An old hand like He Shanheng was called a dog by the younger generation.

Many Chinese businessmen who identified themselves with the above mentioned people did not give Bao Yugang a good look.

Of course, where there are those who oppose, there are those who support.

As the only small boat merchants who could hold on, Xu Aizhou and Tung Chao-Yen supported Pao Yue-Kong with all their heart and soul.

Even the committee's representative, Lin Ran, recommended Pao Yue-kong.

"Doesn't the Xu family need to send someone?" Lin Ran asked.

Xu Aizhou said: "What needs to be considered in these two positions is the interests of the Chinese people.

I'm old and don't have the energy to react. As for my son, he doesn't know how to do anything except rely on his father."
