The train driver in the courtyard

Li Aiguo brought back 2,300 processors from the Guanting Reservoir Chip Base.

Subsequently, researchers from the Red Star Computing Institute developed a special machine for container dispatching based on the principles of special machines for railway networks.

Container dispatch machines are transported to Fenghuo dispatch centers and branches in major ports across the country.

The Red Star Computing Institute was also busy, and developed a general-purpose computer based on the minicomputer.

The memory and operating speed of general-purpose computers are far inferior to those of later computers, and the Windows system cannot run on them.

Li Aiguo settled for the next best thing and created a DOS system. Although the system was simple, it was able to run some small office programs.

With office programs, small games are naturally indispensable.

Inside the institute, Professor Xia Zhongsu looked at the little tank spitting beans on the screen and was a little surprised: "Aiguo, our computer costs at least 5,000 yuan each, and you use it to play games that only children can play?"

"This game is called Tank War." Li Aiguo looked at the game ending screen and started a new game.

He stood up and pushed Professor Xia Zhongsu into a chair: "Come on, play a game and I'll tell you the rules."

"What's so fun about this? I'm an old man, how can I be interested in this kind of thing?" Professor Xia Zhongsu pressed the keyboard reluctantly.

In his opinion, playing with such unreal things is a waste of time.

"Hey, why can't this tank be killed?"

"You're bullying me, right? I, Old Xia, have seen real tanks before. How can I be bullied by your little code?"

"Hahaha, just die! I told you, there's no way you could be my opponent!"

"Fuck, how did I lose?" If Xia Zhongsu hadn't been worried about breaking the keyboard, the slap would have come right down on his face.

"No, no, play another game. Aiguo, what's going on? Play me another game."

Professor Xia Zhongsu looked up at Li Aiguo, and suddenly realized something. He said awkwardly, "I am a computer expert. When I play this game, I am not playing a game, but doing research."

Li Aiguo gave him a thumbs up and said, "That's right, we are not playing games, but doing computer research."

The effect of the tank battle far exceeded expectations, and it became popular in the Red Star Computing Institute in just a few days.

Later, Li Aiguo copied another classic game - Tetris.

The news that general-purpose computers could play games spread quickly.

There are more than 30 general-purpose computers installed in the Ministry of Railways, and long queues always form in front of the computers before the end of get off work.

So much so that Li Aiguo came up with the idea of ​​developing an anti-addiction system.

However, these comrades have been busy all day, so it’s time for them to take a break.

Look, didn’t you see that Minister Teng also specifically called Li Aiguo over?

After playing a game of Tank Wars, he handed Li Aiguo a cigarette and lit one for himself.

"Patriotism, this thing is quite interesting. Is there any possibility of selling it overseas?"

Minister Teng has been in a good mood recently.

With the help of special machines for the railway network, the current operating efficiency of the railway has increased by 49%. By the end of the year, the goal will definitely be achieved.

Computers were also installed in the lake, and the superiors were still concerned about the follow-up promotion work, which led to this conversation.

"Computers are a kind of production tool. They are now all over the country's major cities. It is impossible to hide it." Minister Teng took a puff of cigarette and continued, "Even the Russians know about the railway network and asked us to help them install it. The Iron Alliance also sent someone here."

After saying that, he looked up at Li Aiguo.

Li Aiguo was well prepared and handed over a feasibility document: "Compared with calculators, computers are more complicated, especially processors, which are almost impossible to copy. As long as we can control the processor, then exporting will not be a problem."

"Okay, the Russians are currently spending a lot of money to buy 5,000 railway network minicomputers, and Hungary and Czech have also placed orders for more than 1,000 computers through the Railway Group." After reading the materials, Minister Teng looked up at Li Aiguo and said, "You have a great responsibility to produce so many computers in a short period of time."

What could Li Aiguo do? He could only roll up his sleeves and get to work.

After all, the profit from selling a small machine equipped with a railway network is comparable to the profit of a textile workshop in ten years. This is a truly high-profit product.

Li Aiguo had just started the production work of foreign trade orders with Peng Yunyou. A few days later, Minister Teng called Li Aiguo into his office again.

"I just received a call from the Foreign Affairs Department. The Huo family in Gangcheng is very interested in general-purpose minicomputers. They hope that we can allow them to jointly represent the minicomputers with the Yang family."

Minister Teng had a headache when he said this.
According to the plan of the railway, after completing the orders from the big brother and the little brothers, the general-purpose minicomputers produced will be sold through Hextech Technology Company jointly controlled by the Ministry of Railways and the Runhua Yang family.

This is called: even if the meat is rotten, it's rotten in your own pot.

However, the Huo family has a good relationship with this side.

They have supported the work here since before liberation. After liberation, the Huo family's fleet has risked their lives several times to transport equipment and supplies here.

The Huo family is the one that can raise the flag, they are old friends, and they are important supporters.

The superiors felt a little embarrassed and threw the matter to Minister Teng.

Minister Teng then called Li Aiguo.

Li Aiguo smiled and said, "The market size of minicomputers will far exceed any previous product. It is difficult to quickly promote minicomputers to the world by relying solely on Hextech. Since the Huo family is interested in universal minicomputers, we might as well support them."

At present, domestic minicomputers are about five years ahead of Xiaomei’s.

Li Aiguo needs to roll out the minicomputers in Xiaomei's home and around the world in the shortest possible time.

Just like what the Windows system did to those domestic operating systems back then, it caused the minicomputer plans of large capital companies such as IBM to fail in the womb.

Also.

Li Aiguo actually has a very good impression of the Huo family.

If for no other reason, it’s because Mr. Huo is the kind of person who firmly believes that businessmen have a motherland.

Rather than the so-called: "Business is business."

Hong Kong is a well-informed place.

After minicomputers appeared in the mainland, big businessmen immediately realized that this was a hot commodity that could bring in hundreds of millions of profits.

In the past, because of the existence of Hextech Technology Company, whenever there were new products in the mainland, these people had no intention of being interested.

But this time things were different.

Some large foreign companies have begun to purchase minicomputers at high prices, and some have even suggested that they will accept them even if they are smuggled over.

In the past, goods were only smuggled there from abroad.

Now they are smuggling goods from the mainland. Isn't this going against the will of Heaven?

There is profit only when there is demand.

Where there is urgent demand, there are huge profits.

So these big businessmen are eagerly looking for ways to communicate with them, hoping to get a piece of the pie.

It's just that in the past they had to avoid this place in order to follow John Bull, and there was no way out at all.

While they were still trying to build connections all over the world like headless flies, the news that the Huo family had obtained a small computer sales license from the mainland spread throughout the entire Hong Kong city in an instant.

Those big businessmen all felt a little regretful.

Among them is the Li family.

The old man of the Li family scratched his head and said, "Old Huo looks silly, but I didn't expect that he would get lucky this time."

He was still a little unconvinced: "The conditions I offered are much better than those of Lao Huo. The people over there are also stupid. Don't they know that the higher the profit, the higher the profit? Why didn't they consider me and gave the agency rights to Lao Huo?"

The Huo family was very happy.
Mr. Huo personally sent his eldest son, Xiao Huo, to accompany Yang Jizong to discuss the export of minicomputers.

After Xiao Huo and Yang Jizong arrived in Beijing, they were warmly received by the foreign affairs department and the railway department.

Because both parties knew each other well and had the same goal, they did not worry too much about the profit sharing and the agreement was signed quickly.

In the first batch of Red Flag computers exported, the Huo family received a quota of 5,000 units, and Yang Jizong's Hextech Technologies received a quota of 7,000 units.

When Li Aiguo saw the agreement, he scratched his head and said, "Are you kidding? We are going to deliver 12,000 general-purpose computers within two months. Adding the computers that have not yet been delivered to the Russians and our Eastern European brothers, the total number will exceed 15,000."

He felt that he, a technical researcher, had become a workshop director.

How to do?
Just roll up your sleeves and get to work.

Just when Li Aiguo was busy producing general-purpose computers.

The latest issue of the Annals of Mathematics was also successfully published and was quickly delivered to major cities and universities around the world.

This included the Imperial University in Tokyo.

The Imperial University of these days seemed far away from war and disaster.

Or maybe they never thought that war was a disaster, just that they were defeated accidentally.

There are many cafes of all sizes near the Imperial University.

The cafe is a good place to discuss various academic issues, but the price of coffee is a bit expensive, 50 yen a cup.

In those days, 1 US dollar was equivalent to 360 yen, and Muramasa's monthly salary as an associate professor at the Imperial University would not exceed 65 yen.

Muramasa would spend a full half day in the cafe every day, consume at least two cups of coffee, and go to the Western restaurant next door to order two high-end Western dishes worth 800 yen.

The clothes he wore were also high-end suits from Italy, and he had a famous watch from Switzerland on his wrist.

If someone didn't know Muramasa, they would definitely think he was the son of a wealthy chaebol.

But those who often chatted with him in the cafe knew Muramasa's background - Muramasa's father had once been there as an officer.

Although his father was unable to return in the end, he had taken the opportunity of visiting relatives earlier to bring back a large amount of gold, silver and jewelry.

One can imagine the origin of this batch of jewellery.

Of course, Muramasa never mentioned what his father had done. He often said, "Let the past be the past. We are also victims."

Today, someone brought up the past again. Muramasa drank coffee and said, "In fact, we were just helping them back then, not fighting. We were just misunderstood, and we are the real victims.

Of course, these things have nothing to do with us anymore. Let's solve the Poincare conjecture as soon as possible. We don't want to be like that coward Taniyama Feng, who committed suicide."

When Taniyama Feng was mentioned, the professors felt a sinking feeling in their hearts and glanced at Muramasa with disdain.

Taniyama Yutaka was a lecturer at the Imperial University. He had unique insights into the problem of n-partitions on the field of Abelian functions. He once wrote "Modern Number Theory" and proposed a seemingly useless conjecture with Shimura Goro.

Taniyama Yutaka was considered the most gifted mathematician at the Imperial University, but he suddenly committed suicide in his apartment in 1958. A few months later, Taniyama's fiancée Suzuki Misako committed suicide in the apartment they had planned to use as their new home.

The fall of a genius is always a cause for regret.

Most people felt sorry for Taniyama Yutaka, and naturally felt unhappy when they heard what Muramasa said.

"Muramasa-san, although Taniyama Toyotomi died young, his achievements have surpassed some people." The young lecturer Kudo Shinichi couldn't help but sigh.

The so-called some people naturally refer to Muramasa.

Muramasa is already 35 years old this year. He was promoted to associate professor by accumulating seniority, but he has made no academic achievements.

Muramasa's face turned red as someone hit his soft spot. "I have been studying the Poincare conjecture for years, and I will soon make progress. Once I succeed, I will win the Fields Medal tomorrow."

"Muramasa-san, I heard you say this when I just graduated." Kudo Shinichi has always looked down on mathematicians who just live a lazy life. He said with a smile while drinking coffee.

"Kudo Shinichi, is this how you treat your seniors?" Muramasa was unable to argue with Kudo Shinichi, his face changed, and he started to accuse him.

At this time, there were footsteps outside and a mathematics professor came in with a journal.

"This month's issue of the Mathematical Annals has come out. I wonder if there is any manuscript from our Imperial University in it."

Hearing this, Muramasa perked up: "My teacher submitted a manuscript last month, it must have been published."

The reason why Muramasa was able to survive at the Imperial University and even become an associate professor was because he had a good teacher - Saito.

During the war, Saito cracked the Allied codes for the military and personally optimized the design of naval cannons. He was very famous in the Imperial University.

"Come, let me see!" Muramasa put the coffee cup on the table without saying a word, stood up and grabbed the magazine.

He looked through the whole book but still couldn't find Saito's name. He felt a little embarrassed for a moment: "The teacher's paper must be very difficult and will take a long time to review."

"That's not right. Here is a paper that was published half a month after it was submitted. You see, the editor-in-chief specifically mentioned the submission time in the preface." Kudo Shinichi just turned a page and saw the paper titled "Proof that the Poincare Conjecture is valid under three-dimensional conditions."

When he saw the title of the paper, he was stunned.

"This is the proof of the Poincare conjecture. Although it is only a part, but, but"

At this moment, Kudo Shinichi could no longer express his shock in words.

"This, this is impossible!" Muramasa was even more shocked than Kudo Shinichi.

He has always regarded himself as the future prover of the Poincaré conjecture. Now someone has actually proved the Poincaré conjecture. How incredible!
Muramasa grabbed the journal again.

As time passed, the solemnity in his eyes became more and more obvious.

Seems correct
Maybe correct
Probably correct
It turns out it can still be like this!

The more he read, the depressed Muramasa became. This line of proof was beyond his imagination.

He now felt like he was standing at the foot of a mountain, looking up at a high mountain.

Although he couldn't see the big tree on the mountain clearly because it was too far away, he could still confirm the existence of the tree.

"Who proved it? Professor Lefschetz? Professor Oswald? Professor Whitney?"

Muramasa turned the paper to the front again and frowned when he saw the author's name.

LiAiGuo?
"Which country is this mathematician from? Why have I never heard of him?"

Kudo Shinichi had come to his senses from the shock and didn't bother to argue with him. He pointed to the following words and said, "Contributor Li Aiguo, a student at Tokyo University and a researcher at the Institute of Mathematics and Computing in Beijing."

"Todai? How is this possible?" Muramasa was like hearing a huge joke. "My father has been there, and I know better than any of you. They have no talent for mathematics at all. How could they prove the Poincare conjecture?"

Halfway through his words, Muramasa's eyes suddenly lit up: "Fake! It must be fake! I understand, there is something wrong with this paper. There must be something wrong with the review of the Annals of Mathematics, so it was published. This must be the case!"

When Kudo Shinichi heard this ridiculous statement, he subconsciously wanted to refute it.

Just kidding, this is the "Annals of Mathematics", one of the four most famous mathematics journals in the world. He believed that the editorial office had reviewed the manuscript repeatedly before it was published.

But when he looked around, he found that several professors and associate professors not only did not refute but nodded, and he immediately realized Muramasa's real purpose.

Once a proof is determined to be correct, it is a level of achievement that is enough to earn the prover a Fields Medal.

If it was the Fields Medal in previous years, it wouldn’t matter.

But the next International Congress of Mathematicians may be held at Imperial College.

This is the largest conference in the international mathematics community, held every four years. Being able to host such a conference will bring huge benefits to both the Imperial University and the professors who are affiliated with the Imperial University.

The Imperial University, as the most famous university in Asia, was able to secure this opportunity.

Now that the person next door is about to win the Fields Medal, will it make the International Mathematical Union Committee reconsider the venue of the conference?
You know, the first item of the International Congress of Mathematicians is to award the Fields Medal winners.

Although the big family is divided into east and west sides.

Although the people next door are not of the same kind as here, generally speaking, an important international conference like this one would not be held next door.

The situation in mathematics is rather special.

In the international mathematics family, there are outstanding representatives from both the East and the West.

The Russian school represented by Andrei Kolmogorov and Maltsev had applied to hold the International Congress of Mathematicians in Moscow several years ago.

It's just that they lacked outstanding achievements, so they failed to achieve their goal.

Now a Dongda student has achieved something that could win a Fields Medal.
This is a huge threat to the Imperial University and the entire Tokyo.

That is why these mathematics professors chose to stand on Muramasa's side when they were not sure whether there was a problem with the paper.

Seeing this situation, Kudo Shinichi sighed helplessly.

He knew Muramasa very well. Like his father, he would do anything for profit.

Muramasa's subsequent actions were just as Kudo Shinichi had expected. He took the journal to find his teacher, Professor Saito.

Professor Saito had already seen the paper and was getting angry in his office.

He is responsible for the specific application work for the next International Congress of Mathematicians.

If the application fails, his status in the Imperial University will be affected.

Although the capital city currently has no interest in hosting the International Congress of Mathematicians, the people here are like this; once they are sure that you can pose a threat to them, they will act without hesitation.

There are two results of this action.

One is to knock you down, then he will despise you and treat you like a dog.

The other one is defeated by you, then he will admire you and act like your dog.

The reason why the people here refused to admit defeat was because they believed that they were defeated by the big mushroom and did not fail on the battlefield.

"Teacher, you worry too much. I have thought of a good idea."

Seeing Muramasa's smirk, Professor Saito frowned and said, "Muramasa, this paper was published in the Annals of Mathematics and was reviewed by Professor Lefschetz himself. Professor Lefschetz is the most prestigious expert in topology, so there can't be any problems."

"Teacher, you are so honest. We can..." Muramasa leaned close to his ear and whispered for a while.

Professor Saito's expression gradually changed, and he looked at Muramasa in surprise: "Muramasa, such a vicious idea, no no, such a clever idea, only you can come up with it."

"It's a good idea indeed, but who should come up with it? This person must have a certain reputation."

Muramasa puffed out his chest and said, "Teacher, for the sake of the Imperial University, I am willing to become a soldier charging into battle like my father."

Professor Saito was very pleased after hearing this and patted Muramasa on the shoulder: "Muramasa, when the war is over, I will recommend you to be a professor."

"Yes!" Muramasa was overjoyed.

****
In the Beijing Institute of Mathematical Computing, Professor Hua had just returned from a field trip and had not yet had time to return to his office.

Secretary Chen, who was in charge of overseas journal procurement in the foreign affairs department, walked towards him with a journal in his hand, his face beaming.

"Director Hua, congratulations." As soon as they met, Secretary Chen shook Professor Hua's hand tightly and shook it repeatedly: "Congratulations, congratulations."

Professor Hua was a little confused at this moment.

"What happened to Lao Chen? Why are you congratulating me for no reason?"

Secretary Chen handed the journal to Professor Hua: "Your student, yes, Li Aiguo, his paper has been published."

"Really? That's great." After learning the news, Professor Hua immediately informed Li Aiguo by phone.

Li Aiguo did not expect that the paper could be published so quickly. He put down his screwdriver, changed into clean clothes, and rode his bicycle to the Beijing Institute of Mathematical Computing.

It was already dark at this time, but the lights in the office of the Institute of Mathematics and Computing were still brightly lit.

Li Aiguo walked to the office door and knocked. After hearing a response, he pushed the door open.

As soon as he entered the door, Professor Hua put down the pen in his hand and looked at Chen Zizai who was writing and drawing on the draft paper next to him.

"Xiao Chen, go get your junior brother a glass of water."

Chen Zilan felt a little confused. How did Li Aiguo become his junior fellow apprentice?

Li Aiguo quickly said: "No, I can do it myself."

"No, no, no, please let me come." Chen Ziran came to his senses, picked up the thermos without hesitation, poured a enamel pot of tea, and handed it over respectfully: "Junior brother, please have some tea."

"Thank you."

Li Aiguo was at a loss for words and could only take the enamel pot.

Sitting down on the chair, Li Aiguo saw the magazine on the table, which was the latest issue of "Annals of Mathematics". When he saw the third page, Li Aiguo recognized it at a glance. This was the paper he had written.

"Aiguo, this time you launched a large satellite for our Institute of Mathematics and Computing." Professor Hua said with a smile while sitting behind his desk.

"This is what I should do." Li Aiguo said modestly.

Li Aiguo's calmness made Professor Hua at a loss for words.

To be honest, if he had achieved this result, he would have called a few old friends to have a good meal at Donglaishun.

"Your achievements in topology are beyond my imagination. If possible, I hope you can continue along this path." Professor Hua looked at Li Aiguo and said.

Before Li Aiguo could answer, a voice was heard outside.

"Lao Hua, did you see it? Did you see it?"
