The unparalleled talent of the country started from Harbin Institute of Technology

Chapter 274, Don’t Cry (ask for monthly ticket)

January 10, 1985, the 20th day of the 11th lunar month, was a very ordinary day.

In the Secretary's Office of the Administrative Building of Harbin Institute of Technology.

After Wang Duoyu exchanged greetings with Tong Jianwei, Liu Deben and others, Tong Jianwei did not beat around the bush and went straight to the point.

The reason why Tong Jianwei came to Harbin Institute of Technology this time was that he wanted to discuss and borrow money from Harbin Institute of Technology!

Bingcheng is under a lot of financial pressure this year. They have already applied for funding from higher authorities, but to no avail.

In addition, they still owed funds to the bank and did not embezzle any money at all.

The main problem we are facing now is to prepare for the construction of a high-tech park, renovate the railway station, and build an asphalt road connecting the airport railway station and the high-tech park.

These three projects require a lot of money. We should raise the funds now before the Spring Festival, and start construction after the Spring Festival.

Because foreign companies like Motorola and Nintendo are all talking about this.

They also said that if Bingcheng could successfully complete the construction of the high-tech park in 1985, they would continue to expand their work and introduce other companies to settle in Bingcheng.

For the economic development of Ice City, Tong Jianwei and his team had no other choice, so they set their sights on Harbin Institute of Technology.

"Secretary Tong, if I remember correctly, aren't the roads from the train station and airport to the city already asphalt? Why do we need to build something else? Is the high-tech park located very far away?"

Hearing Wang Duoyu's question, Tong Jianwei smiled bitterly and said:
"That's exactly right. The location of the high-tech park is east of Weizigou. As you know, this place is very close to your Harbin Institute of Technology's new campus. So they also want to get the upper hand."

Airports, train stations and asphalt roads: none of these projects are cheap.

Moreover, they all concern people's livelihood, so Tong Jianwei also knows that they must be confirmed.

So how can he not be anxious?

There is a saying that goes, "Plant a paulownia tree and attract the phoenix."

If the infrastructure of Ice City is not good enough and convenient enough, then foreign companies will definitely not come.

But looking across the country, only Guangzhou, Shanghai and Beijing can surpass Ice City in terms of airports and railway stations. However, in terms of urban infrastructure, Ice City even surpasses Guangzhou, Beijing and Shanghai.

After all, the three cities of Guangzhou have at most cement roads, but the Ice City already has several main roads paved with asphalt, and the roads are very flat and clean.

In this regard, Guangzhou, Shanghai and Beijing cannot compare with Ice City.

Wang Duoyu nodded silently after hearing this, and after thinking for a moment, he said:
"Logically, we should fully support this, but Secretary Tong, you know that Harbin Institute of Technology has basically spent all its money."

"Of course, since you've come here in person, Secretary Tong, it wouldn't be appropriate for us to be completely unwilling to contribute. So, how about we discuss this and then give you an answer when the time comes?"

Delay?

These four words popped up in Tong Jianwei's mind, but there was nothing he could do, because he was the one who came to ask for help.
These days, if you have money, you are the boss!

"Okay, thank you for your patience. I hope you can consider it carefully!"

After Tong Jianwei left, Liu Deben looked at Wang Duoyu and said:
"Duoyu, do we really want to help?"

"Of course!" Wang Duoyu said in a deep voice:
"If we still want to stay in Ice City, we can't just sit back and watch. Besides, the development of Ice City will be of great benefit to us."

“We can borrow money, but we cannot touch the money in the existing account.”

Now it was Liu Deben's turn to be confused. How could he help if he didn't touch the funds in the account?

Wang Duoyu then said that he could directly apply for a loan from the bank and Harbin Institute of Technology would provide the collateral.

The interest should be paid by the Bingcheng Municipal Government.

They can't lend money without paying interest, right?

That’s definitely not possible. If everyone does this, how can this society develop?

Of course, the bank interest rate will not be very high. The specific details will be discussed during the tripartite talks when the time comes.

After hearing Wang Duoyu's method, Liu Deben opened his mouth wide and couldn't say a word for a long time.

Who knew that Wang Duoyu suddenly said at this time:

"In fact, our Lotte Group can also borrow money from banks in Japan and the United States, pay the interest, and then invest the money in the stock market and real estate market."

"As long as we can be more discreet, perhaps we can directly control the market from different places like Wall Street and London, and perhaps we can make a small profit by the end of next year."

After all, this year is 1985, and the Plaza Accord must be signed in September.

As long as the Plaza Accord is signed, countries such as Japan, Germany, and the United Kingdom will sell off US dollars or US dollar assets, causing the US dollar to depreciate, and currencies such as the Japanese yen and the German mark will inevitably appreciate.

Whether the US dollar depreciates or other currencies such as the Japanese yen appreciate, the foreign exchange market is bound to fluctuate violently.

In the financial market, whether it is the foreign exchange market or the stock market, people chase rising prices and sell falling prices. Therefore, the major currencies of several foreign exchange economies: the US dollar, the Japanese yen, the mark, etc., all rise and fall.

Nature is an opportunity.

As for why we are so certain that the Plaza Accord will be signed, we will know after looking at the relevant reports from countries such as Japan, the United States and Germany in a while.

Other things may deceive people, but these report data will never deceive people.

"Duoyu, this won't work. It's too risky!" Liu Deben hurriedly advised upon hearing this.

An aggressive approach is not advisable. This is clearly gambling. How can such behavior be encouraged?

Wang Duoyu shook his head and said:

"You can obviously make a lot of money, why not give it a try?"

No matter what he said, Liu Deben disagreed.

Seeing this, Wang Duoyu was too lazy to say anything more.

Just as he stood up to leave, the phone on Liu Deben's desk rang.

As soon as the phone rang, Wang Duoyu quickened his pace and left.

Unfortunately, he was destined to be busy today, so before he had walked out for long, Liu Deben had already chased him out and took him out.

"The leader is here!"

Who else is coming?
Since he had to go to the door to pick someone up, Wang Duoyu had no choice.

The leader who came from the capital was not Lu Yangui, Fang Lihe, or Li Rui, but someone from the army.

In addition to the leaders, several experts including Qian Xuesen also came along.

This incident seems to be related to the supercomputer at Harbin Institute of Technology.

Wang Duoyu doesn’t know the details yet.

After everyone exchanged pleasantries, the leader expressed his desire to visit the laboratory building where the Dawning supercomputing project was located.

Everyone knew that Harbin Institute of Technology had the Dawning Supercomputing project, but they didn't know the specific situation. They came here without any prior notice.

At the experimental building, Wang Duoyu accompanied the leaders and others to inspect for a while, and then came to the conference room.

Qian Xuesen briefly explained that there was actually a small error in the project he participated in, which was the launch of the geostationary experimental communications satellite.

It is said to be a minor mistake, but in fact it is a major error caused by material problems and other aspects.

It was obvious that before the launch, they had conducted multiple simulations of many situations, and even used the Nebula supercomputer based on 3.2 billion floating-point operations, and used various applications such as computational fluid dynamics simulation software to conduct multiple simulations and mathematical modeling.

In theory, there were no problems with the data and model, and no problems occurred in subsequent simulation tests.

But now after the launch, an accident occurred.

This accident made scientists very anxious.

Therefore, Qian Xuesen personally came to Harbin Institute of Technology to ask if Harbin Institute of Technology could help solve this problem.

Or let Wang Duoyu help solve this problem.

As everyone knows, Wang Duoyu is currently the most comprehensive and powerful mathematician in China, no, in the world.

If there is any mathematician in the world who can solve such a mathematical problem, it must be Wang Duoyu.

Of course, if Wang Duoyu can’t solve it, then there’s really nothing we can do.

"No problem, what's the problem? Let me see what's going on."

Upon hearing this, Wang Duoyu immediately nodded and said.

He has no choice but to take responsibility for this matter.

You know, in his previous life, he respected and admired great scientists like Qian Xuesen.

Although I no longer have that filter after coming into contact with real people in this life, after all, they are flesh and blood people.

But Qian Xuesen has already retired and no longer holds positions such as deputy director of the Commission of Science and Technology. He is just an ordinary old man.

But even after retirement, Qian Xuesen still cared about frontline scientific research and even delved into other industries, such as the sand industry and the grass industry.

Therefore, Wang Duoyu has always admired such a big boss.

However, upon hearing this, Qian Xuesen shook his head and said:

"Not yet, because it involves confidential information, so we can only ask you to go to Beijing to help. In addition, we still hope that Harbin Institute of Technology can help improve the previous Nebula supercomputer first."

"My colleagues and I have roughly calculated that if we use a supercomputer with a floating-point speed of 20 or 30 exabytes, there might be a chance of success. Of course, it's not that we don't trust you, but this time, we've actually conducted repeated calculations and experiments for more than half a year, and the results are still very unsatisfactory."

The technical issues involved in the project of launching a geostationary experimental communications satellite are too many and too complex.

As we all know, common mathematical problems in aerospace mainly include mechanics, astrophysics, orbital mechanics, etc.

For example, very typical orbital mechanics problems, such as orbital velocity, orbital period calculation, orbital transfer calculation, etc.

Take orbital velocity as an example. Given the radius of the Earth, orbital altitude, gravitational constant, etc., how to calculate the speed of a satellite orbiting the Earth? Isn’t this kind of question very simple?
Haha, this is a math problem, but in reality, it doesn’t mean that everything will be fine once you calculate the speed.

When a satellite moves from a low orbit to a high orbit, it needs to consider not only the required speed increment, but also the spacecraft attitude control, orbital maneuvering, etc.

Among them, the more common time series analysis requires analyzing the trends and patterns of spacecraft operation data.

All of the above will involve a large number of mathematical tools and methods, such as matrix operations, vector analysis, gravitational calculations, etc., which are quite complicated.

And this is just the most basic part. When using computers to simulate various data, various problems may still arise.

In the history of the original time and space, why did Lao Yang never go up again after returning from space?
In addition to the need for his protection, not all subsequent spacecraft will be able to return safely after launch.

Therefore, any astronaut is worthy of admiration, because they are risking their lives to blaze a new trail for those who come after them.

Wang Duoyu's face darkened when he heard this, and he nodded.
"Okay, no problem. We'll try our best to cooperate and hope it can be completed smoothly."

"Well, in that case, let's eat first and then return to the capital after lunch. Is that okay?"

The leader has spoken, so of course Wang Duoyu and the others have no problem with it.

So everyone had lunch in the Harbin Institute of Technology cafeteria. The leaders had heard that the Harbin Institute of Technology cafeteria had a wide variety of dishes, so they did not go to the private rooms to eat. Instead, they lined up with student trays to get food.

To be honest, this is indeed rare, but since the leader has such a "refined taste", everyone has no choice but to go along with him.

It is now the middle and late part of lunch, but it can also be said to be the peak dining time.

Although Harbin Institute of Technology has more than one cafeteria, the one that Wang Duoyu and his friends came to is the largest one and the one with the most chefs.

Students also prefer to eat in this cafeteria, so there are many people waiting in line at this moment.

Currently, Harbin Institute of Technology has an annual undergraduate enrollment of more than 8,000 students, and this number will continue to increase in the future.

Including teachers, masters and doctors recruited from outside, the number of new staff added each year is at least over 10,000.

In addition, there are many researchers on various projects on the HIT campus, so the permanent population on the entire campus is at least over 50,000.

A population of this size is almost like a small town.

So there definitely isn't just one cafeteria, but the one Wang Duoyu and his friends came to is the first cafeteria, which is also the largest cafeteria in Harbin Institute of Technology.

Seeing the school leaders queuing up for meals, and the famous Wang Duoyu also holding a menu to get meals, the students queuing next to them all looked at them in surprise.

Wang Duoyu greeted and talked with the students with a smile, while the leaders and Qian Xuesen watched with a smile.

After everyone had gotten their food and sat down at their seats, the leader asked about this matter.

"Professor Wang, it seems you are very popular in school. The students like you very much."

After Wang Duoyu said a few humble words, the leader pointed at the food on the plate and said with a smile:

"Secretary Liu, Harbin Institute of Technology has done a great job on this. The meals the students eat look very appetizing, with a variety of flavors and a reasonable price."

Nowadays, the food coupon system has not been abolished throughout the country, but at Harbin Institute of Technology, food coupons have long been gone.

Due to the development of technology, all teachers and students of Harbin Institute of Technology have started using the so-called meal cards.

In fact, this kind of meal card is not high-tech, it is just a contactless IC card technology. However, the meal card of Harbin Institute of Technology canteen is different from the IC cards outside because it has added a lot of encryption technology, so it is impossible to steal it.

Each meal card has a student's identity card on it. When swiping the card, the cafeteria aunt can see the student or teacher's photo on the display screen.

Generally speaking, it is rare to borrow someone else's meal card to make fraudulent purchases.

If you lose your meal card, you can immediately contact the canteen to help you lock the card.

Even if the money has been swiped, you can still get it back because there are cameras in both the cafeteria and the convenience store.

With so many CCTVs, credit card thieves have no way to escape.

On the other hand, the meal card for the Harbin Institute of Technology canteen can only be used on campus and cannot be used outside the campus.

It is no longer big news that Harbin Institute of Technology does not use food coupons, but the key point is that in the cold winter, the food in the Harbin Institute of Technology cafeteria is still no different from usual.

There are a lot of off-season vegetables, such as eggplant, beans, peppers, cucumbers, water spinach, etc. These vegetables are summer vegetables, but they are common dishes in the Harbin Institute of Technology cafeteria.

There are also seafood, pork, beef, mutton, chicken, duck, goose and other meats.

In terms of nutrition, Harbin Institute of Technology is definitely ranked first.

"Well, our school does subsidize a lot of food every year, so whether it's students or teachers, they don't spend much on each meal."

Liu Deben said with a smile:

"For example, this fried prawn dish uses fresh river prawns shipped from the south. It's hard to find such prawns in the north now. Many students and teachers like this dish very much, so we need to purchase a large amount of river prawns from the south every day. Sometimes we can get them, but sometimes we really can't."

It’s just a dish of fried prawns, but there are many things to it.

Upon hearing this, the leader couldn't help but ask curiously:

“Where did you get those prawns from?”

"Guangzhou!"

"So far? I'm afraid they'd be dead by the time they were transported here."

"Yes, they used to be transported via the Beijing-Guangzhou railway. Even though they were equipped with oxygen generators, most of the shrimp were dead when they arrived at Harbin Institute of Technology."

Liu Deben nodded immediately and said:
"It's okay in the winter, but in the summer, the dead shrimp are not so good."

"Later, someone started breeding river shrimp near Bingcheng. We visited the breeding base and found it was doing very well. The only drawback was that it was a bit expensive."

"However, compared to river shrimp shipped from the south, buying them directly from the surrounding area not only guarantees freshness, but also costs less."

"Air China has already bought the planes. By the middle of the year, they'll be able to open a route from Bingcheng to Guangzhou. By then, fresh river shrimp from there can be flown in."

The leaders, Qian Xuesen, and others were stunned. One of the experts couldn't help but tremble and asked, "Secretary Liu, is this really necessary? Transporting canal shrimp from Guangzhou to Bingcheng? What a waste."

Guangzhou is China's southern gateway and the starting point of the ancient Maritime Silk Road. The Ice City is China's northernmost provincial capital, a vast distance of over 3,000 kilometers. To enjoy this deep-fried prawn dish, they had to airlift the prawns from Guangzhou, a significant expense and time-consuming task.

Liu Deben glanced at Wang Duoyu, then smiled and said to everyone:
"It's not a waste, and it's very necessary. Firstly, our students really like to eat river shrimp, especially the river shrimp from the south, which are very plump and different from farmed river shrimp."

"Secondly, Air China doesn't have many passengers right now, so we're supporting their work."

At this moment, Wang Duoyu suddenly interrupted:

"In fact, we are already building a river shrimp breeding base near Bingcheng, simulating river shrimp breeding in a natural environment and introducing mountain spring water."

The Songhua River runs through the middle of the Ice City, and there are abundant water resources nearby, so there is no shortage of water.

Of course, river shrimp farming requires a lot of water resources.

It is indeed difficult to raise animals in winter, but there are always more solutions than difficulties. When encountering problems, we should face them directly instead of avoiding them.

Therefore, we also need to follow up on the area of ​​river shrimp farming.

Shuanghe County has become a breeding county and a model economic representative of the province.

Perhaps after the beginning of spring this year, many nearby counties will also begin to imitate it.

Once everyone starts to imitate, there is a high probability that there will be oversupply in the market, which will inevitably lead to price fluctuations.

Of course, these are the points that Bingcheng and other relevant leaders should consider in advance, not things that Wang Duoyu and others should consider.

The topic of fried shrimp was discussed in depth at the dinner table.

It started with transportation, moved on to Northern Airlines operations, and then mentioned pioneering technology.

Harbin Institute of Technology has many subordinate units. Pioneer Technology, a company that researches domestic passenger aircraft, has been low-profile since its establishment in December 1983, but it has invested a lot of money.

But there is still no movement at the moment.

Of course, it’s only been a year, what could happen?

Since we are talking about cutting-edge technology, we have to talk about the topic of aircraft.

But the meal time was not very long, so we didn't talk for long before the topic came to an abrupt end because we were done with the meal.

Everyone got up and left the cafeteria, then took a car to Yanjiagang Airport.

During this period, Wang Duoyu called Liu Xiaoli and told her about this.

Wang Junhong, who was standing nearby, heard the call and started mumbling about wanting to go to Beijing with his father, but was rejected.

"Don't cry. If you dare cry, I won't take you on a plane next time."

"Don't cry, don't cry, Dad. When I grow up, I want to be a pilot and fly a plane every day."

"Sure, I support your goal, but you have to study hard. Being a pilot isn't easy."

After chatting with his son for a few words, Wang Duoyu hung up the phone.

At this time, there were also many equipment going to the airport with them. These equipment were the hardware and software that would be used to upgrade the Nebula supercomputer. The technical team also had more than 20 people, and was led by Ci Yungui himself.

Hu Shouqiu, Bao Yuhang, Zhou Yukun and others also boarded the plane.

The flight mission this time was carried out by an Airbus A300, and it was also Wang Duoyu's first time on an Airbus plane. Well, whether it was in this life or the previous life, it was his first time.

In the previous life, the A300 passenger aircraft had been retired and was no longer seen on the market. Well, of course, such old aircraft might be seen in backward places such as Africa and South America.

But Wang Duoyu had not visited many countries in his previous life. He had been to Africa, but he did not happen to have taken an A300 passenger plane.

On the contrary, when he went on a business trip to Africa, because it was a short flight, he took a military transport plane.

Wow, it’s even noisier than ordinary civil airliners, it’s incredibly noisy.

Even within an hour or two after getting off the plane, my ears were buzzing.

After taking a flight like this, he never dared to take such a flight again. It was too scary.

The Airbus A300 took off from the runway of Yanjiagang Airport. When the pilot pulled up the joystick, the plane lifted its head and soared into the sky, and the journey officially began.

On the plane, the leader brought the noise-canceling headphones prepared by Wang Duoyu and others. After putting them on, his face was full of surprise.

"Professor Wang, is this a product developed by your Pioneer Technology? This is amazing."

Seeing the leader giving a thumbs up and praising him endlessly, Wang Duoyu just smiled and said a few humble words.

Because the noise is so loud, you need to speak quite loudly when communicating.

Civil airliners from the 1980s still had a lot of room for improvement in terms of noise reduction.

It will take a lot of effort to reduce the noise to 70 or 80 decibels, or even lower.

Pioneer Technology's current main focus is aviation engines and noise reduction technology. Although relevant departments have been established for other components of civil aircraft, there are not many people.

If there are not many technicians, it will be very difficult to develop good technology.

A towering building rises from the ground, and you can only rely on yourself to achieve glory.

Given Pioneer Technology’s current situation, it is just the beginning of a long journey, and there is still a very long way to go.

More than an hour later, the plane landed safely at Nanyuan Airport and all equipment functioned smoothly.

The flight was exceptionally stable, and even the air currents encountered in the air were not very strong.

Very comfortable!
It was already around three o'clock in the afternoon. Wang Duoyu and his team did not delay. After arriving at the Fifth Hospital compound by car, they started to get busy.

Fang Lihe actually came over to show some concern at this time, but he didn't know why he didn't lead the team to Harbin Institute of Technology this time, but instead gave it to another leader of the army.

Wang Duoyu doesn't care about this. His current idea is to upgrade the Nebula supercomputer.

It hasn’t been that long since the Sugon supercomputing project was launched, only two or three months.

In other words, the current Nebula supercomputer is actually the most powerful supercomputer in the world. But even so, Qian Xuesen and others still think it is not enough.

"Professor Wang, let me handle the upgrade. You go look at the information. Director Qian may need you more."

Ci Yungui suggested this, and Wang Duoyu shook his head:
"No rush, let's upgrade the Nebula Supercomputer first. I'll first determine the general idea."

A Nebula supercomputer with a floating-point operation capacity of 100 exaflops is still not enough, but 200 exaflops or 300 exaflops requires higher technical skills, which may not be achieved by Ci Yungui and others with their capabilities.

So Wang Duoyu will first help complete the design of the overall framework, and it will not be too late to leave later.

For the next day and a half, Wang Duoyu stayed in the office in the compound, busy upgrading the Nebula supercomputer.

It was not until the morning of the 12th that Wang Duoyu saw the problems that Qian Xuesen and others had mentioned.

There was a lot of information, including mathematics-related materials, drawings, etc., which filled more than five large boxes.

Wang Duoyu listened to Qian Xuesen's team's explanation while looking through the materials. After a while, he said:
"Hearing what you said, I really can't calculate accurately. Let me read all the information and then help you solve this problem."

Everyone was stunned, and Qian Xuesen frowned and said:

"Professor Wang, if that's the case, it would take at least half a month or even a month to finish reading all this information. Wouldn't that take up too much of your time?"

Everyone knows that Wang Duoyu's time is very precious, and it is naturally not a good idea to waste half a month or a month here.

Although their project is important, Wang Duoyu's work is also very critical.

"Oh, these materials won't take up much of my time. One day should be enough. Let's leave it at that for now. I'll read the book first, and you guys can go about your business."

Hearing this, everyone was stunned again.

Can I finish reading all this information in one day?

Isn't it too scary?
What kind of person can do this?
Several experts couldn't help but frown, but didn't say it out loud.

After all, the information in the five boxes is the result of their research over the past three years, and it is all cutting-edge technology.

Even if they did it themselves, it would take at least half a month to finish reading all the information.

Moreover, I just glanced through it, swallowing it whole, and there was no way I could digest it quickly.

What's more, Wang Duoyu is a mathematical researcher, not an expert in aerospace research. How can he finish reading it in one day?

Even bragging like this is not allowed, right?
Qian Xuesen didn't say anything. He also wanted to know whether Wang Duoyu could create a miracle.

Although it was highly unlikely to be completed, he saw Wang Duoyu carefully looking through the information, but it was really just a cursory glance.

The legendary photographic memory isn't that exaggerated, is it?
At lunch time, Qian Xuesen and his colleagues were eating in the canteen of the compound, while Wang Duoyu was still looking through documents in the office. He asked his secretary Su Zhenghuai to help him get the food and take it home.

"Director Qian, do you think Professor Wang can help solve this problem?"

"Yes, after reading all that information in one day, I really wanted to refute him, but I saw that Professor Wang was so serious."

Listening to the idle chatter of several colleagues, Qian Xuesen frowned and said:

"Don't talk about this behind my back. You're not gossipers. Why are you discussing this?"

They say they won’t discuss it, but besides being experts, they are also human beings.

As long as one is a human being, he or she will inevitably have curiosity and a competitive spirit.

These experts would need more than half a month to read through the information, but Wang Duoyu finished it in just one day. Who would believe that?

You can't say that Wang Duoyu has read this information in advance, right?

That is definitely impossible, because their project is top-level confidential. It is impossible for people who are not involved in this project to see this information.

Even Qian Xuesen would not reveal this information to Wang Duoyu in advance.

So the current situation is that we have to wait until tomorrow to see whether Wang Duoyu is just bragging or he is really powerful.

In the blink of an eye, it was the next day.

Wang Duoyu did not stay up all night. He got up early in the morning, washed up, and started calculating.

He did not leave the compound last night, but instead put a small bed in the compound's office and made do with it for the night.

As long as the problems of their project are solved, Wang Duoyu can return to Ice City.

So he felt a little regretful. If he had known earlier, he should not have helped Ci Yungui, but came to the Fifth Academy first.

However, this little thought only stayed in his mind for a while, and the emotion soon faded away.

When Qian Xuesen and others came to work, they saw a lot of manuscript paper in front of Wang Duoyu, which was filled with a large number of mathematical symbols.

Everyone stared at the scene in front of them with wide eyes, almost unable to believe their eyes.

Have you finished reading all the information?

And now the calculation is being carried out?

Qian Xuesen and his colleagues did not dare to ask, but returned to their workstations and worked silently.

At this time, Wang Duoyu had entered a state of oblivion of himself and the world, and he was busy all the time, with his brain running even faster than before.

The neurons in his brain were extremely sensitive because he was busy calculating the strong solution to the Navier-Stokes equations.

He had previously completed several related theories, such as the singularity energy gradient theory and several other tools, and verified and demonstrated these theories or tools on the Mach 5 fighter project.

As we all know, if the strong solution of the Navier-Stokes equations can be successfully derived and proved, it means that the flow state at any time point can be accurately predicted from the initial state.

It is naturally very difficult to achieve this.

However, today's Wang Duoyu has created two major mathematical tools, one is the theoretical model of the time axis, and the other is the mathematical formula of the space axis.

Combining these two mathematical tools, Wang Duoyu used mathematical tools such as the singularity energy gradient theory he had derived previously to derive and calculate the problems encountered in the current geostationary orbit experimental communications satellite project.

Wang Duoyu had previously derived the weighted essentially non-oscillatory algorithm, a high-order precision numerical calculation method mainly used to solve convection terms in partial differential equations, especially when dealing with problems with discontinuous or sharp gradients.

After using so many tools, Wang Duoyu believed that he could definitely solve the project problems.

When he was looking through the materials yesterday, his brain was constantly organizing the information and thinking of other solutions.

For him, doing three or five things at once is no problem.

Of course, it is best not to do this when performing calculations or reasoning.

After all, even the best mathematicians make mistakes.

This is because some mathematical problems involve not just simple spatial points and surfaces, but also calculations at other levels such as time orders.

Near noon, Qian Xuesen and his friends were about to go to lunch. At this time, Wang Duoyu suddenly put down the pen in his hand and said to Qian Xuesen happily:
"Professor Qian, I've figured it out, haha."

Is it really solved?

Everyone was stunned for a moment, and then the next moment they all came to Wang Duoyu excitedly.

Qian Xuesen was also a little excited. Although he was not the main person in charge of this project, there was no doubt that this project was also related to the domestic aerospace industry and was very important.

The United States and the Polar Bear Empire have already come very far in the field of aerospace, but our country has not done very well in the field of aerospace so far.

The four words "slow and steady wins the race" are not so easy to achieve.

After all, you have to accumulate experience, but it’s a pity that you have wasted a lot of time before.

After looking at Wang Duoyu's calculation results, Qian Xuesen and others frowned because they seemed to not understand the results given by Wang Duoyu.

Simply put, the mathematical symbols written by Wang Duoyu are not the symbols they recognize.

What’s going on?

Wang Duoyu explained to them with a smile, because he used new mathematical tools and theories, including the singularity energy gradient theory, the weighted essential non-oscillation algorithm, the discontinuous Kallior-Kin method calculation method, etc., which are all very novel.

Although these mathematical tools have been created by Wang Duoyu, basically only people with a certain level of mathematical ability can understand them, and only researchers involved in domestic aerospace-related projects can access these papers.

Just because these papers are not open to the public, the confidentiality level is also very high.

On the other hand, only a small number of people like Wang Duoyu can understand and learn these mathematical tools, while others simply cannot understand them.

In addition, these mathematical tools are also being argued, so even fewer people know about them.

"I used new mathematical tools. You can learn the specific methods, but it may take more than half a year, so I won't explain them in detail. However, you can use these results to conduct simulations and demonstrations."

Everyone was stunned when they heard Wang Duoyu's words.

Qian Xuesen nodded and said that it was no problem and they would discuss it clearly in the next period of time.

Just like quantum mechanics, many scientists only know what it is but not why it is. However, this does not prevent everyone from using these theories and then using them for our benefit.

For example, the energy band structure and conductivity characteristics of semiconductor materials are explained by quantum mechanics, which provides a theoretical basis for the design of electronic components such as transistors and integrated circuits.

So Wang Duoyu did not explain these mathematical theories to them clearly, and was too lazy to explain them to them.

As for tools, just know how to use them. Why delve into so much detail?
But the most important thing now is eating!
Nothing else matters, eating is the most important thing.

After all, he didn't eat much for breakfast today.

Just at this moment, Fang Li and several of their leaders walked in from the office door.

"I heard your movements from a long distance away. Have you figured out the result?"

The arrival of the leaders forced Wang Duoyu to pause for a moment. After a brief explanation, he directly said that he was hungry and needed to eat.

"Let's go, let's go eat now. We can't let our great scientist go hungry."

Fang Lihe immediately said, Qian Xuesen and the others did not delve into the calculation results any further, let's eat first.
