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

Chapter 314 Materials Enter the Pit and Steal (Bonus Chapter, Please Vote)
July 2, 1987. Summer vacation was approaching, and the final exam season at Harbin Institute of Technology was about to end.

However, none of this had much to do with Wang Duoyu.

That evening, Wang Duoyu came out of the study of the villa and was greeted by Zheng Baodong, who was frowning.

"Baodong, are you having some kind of trouble?"

Upon hearing the sound, Zheng Baodong looked up and quickly forced a smile, saying:

"Uncle, you're off work? Well, I've run into a problem lately."

Zheng Baodong passed the entrance exam for the Harbin Institute of Technology's gifted program in July 1981 and was admitted to the program.

The gifted program is a six-year program that leads to a master's degree. Zheng Baodong just graduated last month, but he has already applied to a professor in the Department of Materials Science for a doctoral program.

As is well known, doctoral programs are based on an application process.

But there are definitely quotas. Just like Wang Duoyu, he actually has ten doctoral student slots, but he only takes on one or two doctoral students each time, and he is unwilling to take on more than that.

In China, Wang Duoyu is the only one who has received such a prestigious award.

Most professors have two or three spots, academicians have about four or five, and Wang Duoyu has ten spots, or even twenty if he wants.

After graduation, Zheng Baodong devoted himself to materials research, working on research projects with the professor in the materials department.

Sure enough, they recently encountered a major problem in a research project on photosensitive materials.

All the calculations and experimental procedures were perfectly correct, but the experimental results were still incorrect.

"Uncle, we've completed many experiments and calibrated and checked them multiple times, but we just can't find the reason for the failures. It's driving us crazy!"

Upon hearing this, Wang Duoyu comforted him:

"Take it slow. Problems will arise in experiments; that's common. There's a saying: 'Being too close to the situation prevents you from seeing the bigger picture.'"

"Sometimes, you need to step back, observe more closely, eliminate all the impossible possibilities, and the last one left, no matter how unbelievable, is the truth."

The Department of Materials Science and Engineering at Harbin Institute of Technology is one of the largest departments in the university. While it may not be as well-known as the Department of Mathematics, it is definitely number one in terms of student numbers.

The mathematics department is very strong, with many Fields Medal winners, which makes it extremely attractive to top scorers in the college entrance examination.

The Department of Materials Science and Engineering has a large number of majors and therefore a larger student body.

For example, the core major of the Department of Materials Science and Engineering is Materials Science and Engineering, which has four classes at Harbin Institute of Technology, with a very large number of students.

Other related fields include materials physics, metallurgical engineering, materials chemistry, metal materials plants, polymer materials and engineering, composite materials and engineering, welding technology and engineering, functional materials, new energy materials and devices, optoelectronic information materials and engineering, biomaterials, and composite material molding engineering.

Zheng Baodong chose optoelectronic materials as his doctoral research direction, which is also highly related to other directions in the Department of Materials Science.

"Okay, Uncle, I understand." Zheng Baodong was confused, but he still nodded in agreement.

Although he knew his uncle couldn't help him with materials research, and he didn't need such help, his uncle's words of comfort still warmed his heart.

"Let's go eat."

Wang Duoyu smiled. He had already seen his eldest son rush out, shouting, "Dad, dinner's ready! Cousin, dinner's ready!"

During the meal, Wang Meili mentioned their experience of a power outage in Tokyo.

"Our Ice City is still the best; at least we've never had a power outage."

"Yes, brother, you don't know, when my sister and I were in Tokyo, we experienced power outages every few days. They say Tokyo is an international metropolis, but it's because the power plants haven't been repaired after the earthquake, so they can't provide power 24 hours a day."

Japan is an island nation located on a continental seismic belt, so it frequently experiences earthquakes.

Furthermore, there are severe natural conditions such as tsunamis, typhoons, and torrential rains. Although Tokyo is an international metropolis, it is not a livable city.

The two sisters had just returned not long ago, and they would go back to Tokyo in a while.

As time went on, Tokyo real estate and the stock market continued to rise. However, the Japanese stock market will be affected by the US stock market crash, so Maple Leaf Holdings has temporarily taken profits and exited the market.

It's July now, and although the US stock market crash hasn't happened yet, Maple Leaf Holdings has already sold off its entire stake and left the market.

Having cash on hand makes it easier to buy at the bottom during a stock market crash.

Shorting US stocks is short selling, which involves two different types of funds than bottom fishing.

Wang Duoyu wouldn't bet all his funds on shorting US stocks; instead, he would diversify his investments.

Moreover, although the US stock market financial crisis had a far-reaching impact, causing stock prices to plummet and a lot of funds to evaporate from the stock market, more than 20 billion US dollars is no small amount.

This is why the Wang sisters often need to travel to Tokyo on business trips to keep an eye on the inflow and outflow of funds.

Hearing the two sisters' complaints, Zheng Baodong chimed in:
"Speaking of which, I just remembered that our lab also had a problem with flickering lights."

Is there any connection between power outages and flickering lights?
"Is it caused by unstable voltage?" Wang Duoyu asked immediately.

"This flickering light is usually caused by unstable voltage. Go back and have someone check the fuse."

Harbin Institute of Technology has ample power plants to ensure sufficient electricity supply.

Around Harbin, there are hundreds of thermal power plants of all sizes, and the Songliao Canal project, which is currently under construction, has also launched many reservoir and hydropower plant construction projects.

It is even less likely that Harbin will experience power shortages in the future.

It's not just the massive Harbin Institute of Technology group, but also Want Want Group and an increasing number of foreign companies; ensuring power supply is the most important task for the Harbin municipal government.

And it's not just industrial electricity; residential electricity supply must also be ensured to be sufficient.

After all, Harbin is developing rapidly, and the relevant supporting measures must keep up; otherwise, those talented people may not be willing to settle in Harbin.

Therefore, within the Harbin Institute of Technology campus, whether in laboratories or ordinary student dormitories, it is highly unlikely that the lights will flicker.

"Of course, besides unstable voltage, other potential problems include reversed live and neutral wires, circuit malfunctions, and poor contact. In short, you should find an electrician to fix this problem."

After a pause, Wang Duoyu continued:

"This might be the reason your experiment failed, especially since your research concerns technical issues related to photosensitive materials; you should definitely consider this factor."

Upon hearing this, Zheng Baodong was stunned for a moment before he came to his senses.

"Thank you, Uncle. I understand. I'll go try it right away!"

He immediately put down his chopsticks and ran away as fast as he could.

Why are you running so fast? Bao Dong, aren't you hungry?

"Auntie, I'm not hungry, I'll go now."

The sound was still loud, but the person had already run far away.

Liu Xiaoli and Wang Meihe both shook their heads. Wang Junhong and the other kids didn't quite understand. They just thought their cousin was crazy and silly. It was just an experiment. How could it be as delicious as food?
Wang Duoyu smiled but didn't say anything.

That's how researchers are. When they get an inspiration or come up with a solution, no matter if they're in a hurry or not, their first priority is always solving the research problem, not anything else.

"Brother, does our school have several supercomputers? Aren't those computers incredibly power-hungry? If Harbin were like Tokyo, wouldn't it be very possible for them to..."

After Zheng Baodong left, Wang Meili suddenly said.

"That's definitely impossible!" Wang Duoyu shook his head.
"Not to mention that Harbin Institute of Technology itself has a sufficient power supply, and we also have backup power supplies and backup generators, so it is impossible for any accidents to happen."

"Alright, stop worrying about electricity. It's not your business."

"Next time you go to Tokyo, keep a close eye on those funds and the stock market fluctuations."

"Just let me know if anything seems amiss."

With the advent of communication networks, Wang Duoyu's connections with the various leaders of Want Want Group have become much closer.

This time, Want Want Group has put up more than 20 billion US dollars to short US stocks, so he has to be cautious.

If he hadn't been unable to travel abroad, and if Liu Xiaoli hadn't been heavily pregnant with her due date in late August or early September, he would definitely have gone to New York to oversee the operation.

Unfortunately, he can't leave!

"Okay, brother. My sister and I will keep a close eye on things, so don't worry."

"Brother, we understand!"

The next day afternoon arrived in the blink of an eye, and Zheng Baodong suddenly ran back excitedly.

At this time, Wang Junhong and his friends were chasing and playing in the yard, with their little desks nearby.

Although it's July now, summer vacation hasn't started yet, so Wang Junhong and his friends are having classes in their own little classroom.

Every day, I either practice writing, do exercises, or memorize texts.

Of course, Wang Jun'an, Li Rongrong, and Lu Yuening are the three younger children, so they are learning to read and write, and they have quite a lot of homework.

"Baodong, why are you back again? Don't you need to do the experiments anymore?"

Liu Xiaoli, heavily pregnant, was exercising by walking around the doorway when she saw Zheng Baodong and asked him with a smile.

Wang Meili and the others also came out of the house in surprise, only to hear Zheng Baodong say the following:

"Auntie, Auntie, I'm here to report to Uncle that our experiment was a success. It turns out that a faulty fuse connection caused voltage fluctuations, resulting in a 15% fluctuation in light intensity and disrupting the light absorption stability of the photosensitive material."

Zheng Baodong said a lot of things, but Liu Xiaoli and the others only understood that the experiment was successful; they didn't understand anything else.

"My uncle is really amazing. He deduced the reason for the experiment's failure based on just one sentence from me, while my colleagues and I went in and out of the lab every day without ever thinking of that reason."

The laboratory's lighting switch fuse is malfunctioning, causing the lights to flicker intermittently.

Zheng Baodong and his team were busy with their experiments and didn't pay any attention to these trivial matters.

In their view, experimental failures are related to calculations, experimental procedures, materials, or experimental direction.

To everyone's surprise, it turned out to be due to a faulty fuse connection.

Wang Duoyu is still in the study at the villa and hasn't come out.

Lately, he has been busy with the phonon conjecture, a problem he has been studying for more than half a year, and he is completely absorbed in it.

This also shows that the difficulty of the functor conjecture far exceeds that of the mathematical conjectures he completed before.

"It's almost finished! It's been so difficult!"

Inside the study, Wang Duoyu looked at the math draft paper in front of him and said softly with a smile.

He was immersed in the problem of the functor conjecture for such a long time, an experience he had never had before.

If he still hasn't proven it by October, then it will have been more than a year.

This is absolutely unforgivable to him.

He has now solved the main problem in what he considered the toughest challenge.

There are still some less important but still important points left for him to complete.

Once completed, the problem of the functor conjecture will be completely solved.

As is well known, the functor conjecture is the key to building a 'grand unified theory of mathematics', and its geometric version, the geometric Langlands conjecture, has been proven by Wang Duoyu.

Therefore, once Wang Duoyu has thoroughly proven the functor conjecture, the most important key in the Langlands program will be completely proven, and then it will be linked with the geometric Langlands conjecture, laying the foundation for this 'grand unified theory of mathematics'.

If Wang Duoyu were to publish all of his proofs of the functor conjecture, it would be a groundbreaking scientific achievement that would shock the global mathematical community.

A math report meeting will be necessary in advance.

However, there's no rush right now, because Wang Duoyu hasn't finished yet and needs more time to mature.

In the evening, Wang Duoyu came out of the study and learned from Liu Xiaoli and the others that Zheng Baodong had found the reason for the experiment's failure and successfully completed the experiment.

"That's great, it's good that it can help him."

Wang Duoyu smiled and nodded, "Baodong is a genius, he has a great talent in materials science. I support his willingness to study scientific problems in this area and hope he can go even further."

The Department of Materials Science and Engineering at Harbin Institute of Technology is undoubtedly one of the strongest departments in China. In many fields of materials science, the Department of Materials Science and Engineering at Harbin Institute of Technology has been at the forefront of the country and even the world.

Materials are a crucial discipline in many modern industrial applications.

Take the timing belt, a seemingly insignificant component of a car, as an example. The timing belt is an indispensable part of the car engine, and its role is crucial.

It can precisely coordinate the opening and closing timing of the engine's exhaust valves, thereby ensuring that the engine can operate smoothly and efficiently.

The material requirements for timing belts are higher than you can imagine.

First, timing belts need to continuously mesh and rotate with gears at high speeds for extended periods. This requires timing belts to have excellent wear resistance and fatigue resistance, both on the tooth surface and the back side.

Secondly, the timing belt must be kept in place and operate normally under high load conditions; otherwise, it will cause timing deviation of the engine and damage the engine.

Therefore, timing belts are required to have excellent tensile strength and dimensional stability.

Third, in places like Harbin, the winter temperature is very low, while the engine compartment temperature is very high after the engine has been running for a long time. The belt needs to remain stable and operate normally regardless of whether the temperature is low or high.

Therefore, the timing belt needs to have excellent high and low temperature resistance.

Fourth, timing belts inevitably come into contact with corrosive or aging liquids such as engine oil and coolant inside the engine, which also requires the belt to have very good oil resistance and chemical corrosion resistance.

Finally, the engine operates under various conditions, such as starting, idling, and rapid acceleration, which place different loads on the timing belt.

Therefore, to ensure that the timing belt can operate stably under any working conditions, the belt must have very strict dynamic load adaptability.

These performance requirements necessitate extremely stringent research and development standards for the main material of the timing belt. Why?
The reason is simple: the engine timing belt is not a wear part or an aftermarket part. Its design life is matched with the engine to achieve long-term durability.

In other words, they are all designed with a minimum lifespan of ten years or 240,000 kilometers.

Besides the difficulty in developing the main material of the timing belt, another challenge is to change the quality and performance of the material by adding different additives, such as antioxidants, plasticizers, anti-aging agents, modifiers, etc.

The selection and proportion of these additives constitute the technological barriers established by major car brands.

Even something as simple as a timing belt has so many technical requirements.

Moreover, the engine timing system is a complex and precise device, which includes multiple components such as idler pulleys, tensioner pulleys or tensioners, pulleys, belt guide brackets, camshaft pulleys and sprockets.

These components work in coordination to ensure the engine operates properly.

Therefore, there is no shortcut to industrial development; it is a massive system.

The timing system of a car engine alone involves so many complex and precise technical processes, not even counting the machine tools and other auxiliary equipment needed to develop this system.

China has a long way to go to catch up with Europe and the United States.

"Dad, I want to be like my cousin and become the most amazing materials science PhD in the future!"

Just then, Wang Junhong suddenly spoke up.

"Junhong, you're not going to be a pilot anymore?" Wang Meili teased with a smile.

The little guy loves flying, especially this year. He hasn't flown for almost a year and often talks about it with his father.

Unfortunately, his father wasn't on a business trip, so he couldn't go on the plane with him.

Therefore, the little guy set a goal: to become a pilot when he grows up, so that he can fly every day.

"I definitely want to be a pilot! After I become a pilot, I'll become a materials science PhD!" Wang Junhong's voice was young, but firm and powerful.

Liu Xiaoli jokingly added:
"Why don't we become pilots together? You can be a pilot or a materials science PhD in the future!"

Wang Duoyu quickly said:

"Alright, stop setting a bad example for the children!"

"If you want to be a pilot, you need to enlist in the army first. Not only do you need to be good at math, physics, and chemistry, but you also need to learn aerodynamics and other subjects. At the same time, you need to have a very strong body, and most importantly, you can't be nearsighted."

Upon hearing this, the little guy nodded seriously, indicating that he would definitely do it.

A child who is over six years old has a strong sense of self-esteem and whose values ​​are still being formed.

The environment in which Wang Junhong was situated was exactly like that, with an incredibly strong academic atmosphere.

Although he often lived with Liu Xiaoli and the others, he was more influenced by his father.

Whether it's mathematics professors like Shing-Tung Yau, John Milnor, and Charles Fefman, or people like Liu Deben, or other professors from Harbin Institute of Technology, they all frequently visit this island in the middle of the lake. He used to often accompany his father to Beijing or other places, and saw far too many of them.

Even when he was young, he had already set his sights on becoming a pilot, and from then on, he lived a life of flying planes every day.

Now he even wants to become a PhD in materials science, a goal he set because of his environment.

"Dad (Uncle), I want to be a pilot and a materials science PhD too!"

As soon as the little guy finished speaking, Li Rongrong, Lu Yuening, and Wang Junan, the three little ones, also chimed in, saying that they were just there for the fun of it.

Even Wang Junkang, a little kid who is only one year and three months old, started babbling along.

Haha!

The adults were all laughing heartily. The little kids didn't understand, but seeing the adults laughing, they laughed along, and the atmosphere in the room became very lively.

The Barbus clock on the wall ticked away, and time quietly slipped by.

In the blink of an eye, a few more days passed.

Summer vacation has officially arrived, and Harbin has finally ushered in the dog days of summer.

"it is finally over!"

Inside the study villa on the island in the lake, Wang Duoyu smiled easily.

All the problems of the functor conjecture have been solved, and he can finally relax.

"However, I will need to spend some time revising the paper next."

This mathematical conjecture includes the Artin conjecture, the Ramanujan conjecture, and the Sato-Tate conjecture, resulting in Wang Duoyu ultimately compiling a total of seven papers.

Furthermore, among these seven papers, the minimum is 227 pages, and the longest is 562 pages.

This gives an idea of ​​just how difficult the fuzzy conjecture is.

After more than a week, Wang Duoyu finally finished organizing his last paper.

Then, using a printer, I printed out the paper.

He didn't just print one copy; he printed out five copies of the paper and placed them in different locations.

Although he can still save his papers on his computer's external hard drive, he still prefers to print them out and store them in separate alloy boxes in different locations.

Currently, the research results inside the alloy box are two: infinite-dimensional partial differential equations and the functor conjecture.

The Kauraz conjecture was published last year, and the Banach hyperplane problem was published in the first half of this year.

In that case, let's publish the infinite-dimensional partial differential equation in the second half of the year.

There are as many as seven papers proving the functor conjecture, which can be published gradually.

Next year is 1988, which isn't a particularly crucial year. The International Congress of Mathematicians will be held in 1990, so there's no rush.

After clarifying his next plan, Wang Duoyu put away his thesis and prepared to take a few days off.

Last year, his way of relaxing was to travel and see the sights in many places.

But not this year. He needs to stay with Liu Xiaoli because she can't go around. After all, she's almost due and could be in the delivery room at any time.

So his current way of relaxing is fishing.

And it's located right next to the fishing spot on the island in the middle of the lake, something that was considered when the island was built.

Wang Duoyu came fishing with a fishing rod and hook, which immediately attracted the attention of the little kids.

"Dad (Uncle), are you going fishing?"

"Yes, do you guys want to go fishing together?"

Of course we have to go together! How could a little kid not want to join in the fun?

For the next few days, Wang Duoyu fished on the island in the middle of the lake.

This unusual behavior aroused Liu Xiaoli's curiosity.

However, after Wang Duoyu casually explained, she understood.

Anyway, she wouldn't understand anything about scientific research.

However, Wang Duoyu's leisure time was less than five days before news of his fishing trip somehow spread, and Smail was the first to rush over.

"Wang, why didn't you call me when you wanted to take a vacation and relax?"

Smail is already fifty-seven years old, and his hair has started to turn gray; he is aging very quickly.

However, this guy looks very old, but he has a great attitude.

Especially after moving to Harbin Institute of Technology, his life has become significantly better than before.

Sure enough, this old fellow walks with light and quick steps, much younger and more energetic than John Milnor and the others.

"I remember you don't like fishing, so I didn't call you."

Wang Duoyu chuckled, but then heard the other person mutter an explanation:
"How could that be? Of course I love fishing. You must have misunderstood me before."

Not long after sitting down, Smail began mysteriously asking Wang Duoyu for information:
"By the way, have you finished any research? Where's the paper? Can I take a look at it first?"

"See, I knew you didn't like fishing, wasn't I right?" Wang Duoyu immediately rolled his eyes.

Smelton was a little embarrassed. It was fine for him to sit by the lake for a while, but he certainly wouldn't be happy to just sit there and daydream.

Everyone has different preferences. Fishing may seem like a very boring "sport", but many people get hooked on it and become deeply addicted.

After being exposed, Smail stopped pretending and urged Wang Duoyu again to tell him where the paper was located.
"What's the hurry?"

After rolling his eyes at the other person, Wang Duoyu pointed to the fishing gear next to him: "Fishing with me for a while, if you can catch three fish, no matter what weight they are, I'll let you read my thesis, how about it?"

"A gentleman's word!"

"It's hard to chase a horse!"

And so, Smail fell into the trap.

Before Smail could even catch a fish, Shing-Tung Yau, David Bryant Manford, Jean Burgundy, and others had already rushed over.

More than ten minutes later, on the shore of the island in the middle of the lake, Wang Duoyu and his group lined up and were all fishing. The scene was quite interesting.

This large lake is stocked with many kinds of fish, including sturgeon. It would be extremely difficult for these fish to eat up all the other fish in the lake.

The lake is not a dead lake; it has fresh water flowing in, specifically from the Songhua River, which then flows downstream into the Songhua River.

Therefore, it is possible that some fish from the upper reaches of the Songhua River may enter this large lake through the water flow.

Although the lake is full of fish, the fishing skills of Wang Duoyu and his fellow math professors are, to put it mildly, lacking.

Moreover, fishing is primarily for entertainment; they spend most of their time chatting.

That evening, Yau Shing-Tung and his colleagues left satisfied, each with their papers in hand.

Wang Duoyu didn't make things difficult for them; he just asked them to keep him company and chat, nothing more.

It was casual conversation, not an academic discussion.

The proof of the infinite-dimensional partial differential equation has been submitted to Shing-Tung Yau and his team for review, and will be published once the results are available.

After submitting the paper, Wang Duoyu went to the Yuanchang Large Wind Tunnel Laboratory to find Xu Yimin and the others to learn about the current research and development progress.

Xu Yimin had approached Wang Duoyu before, but he was busy at the time.

He has now completed the functor conjecture problem in one go, and after a few days of rest, he finally has time to deal with these tasks.

"Professor Wang, you've finally arrived."

Xu Yimin and the others were very happy to see Wang Duoyu arrive.

The turbo-based combined cycle engine is currently the most cutting-edge technology. Although Xu Yimin and his team were not responsible for designing it, turning it from blueprints into a real product took them a lot of time and effort.

Materials are the core issue they need to solve.

Although the project has no shortage of money or manpower, it lacks a core leader, and Wang Duoyu is the soul of the project.

Therefore, they urgently need Wang Duoyu to come to the scene to take charge.

"Well, everyone sit down and tell us about the current progress," Wang Duoyu said with a gentle smile, waving his hand.

Suppressing his excitement, Xu Yimin said loudly:

"Yes, Professor, we previously designed the air intake profile based on your design for a variable geometry intake for an internally parallel turbine-based combined cycle engine, and conducted numerical simulations of its two-dimensional flow field."

As he spoke, Xu Yimin manipulated the remote control, then pointed to the display screen and continued:
"These are the flow field characteristics of the air intake under various typical operating conditions. Without using boundary layer suction, the air intake can maintain normal operation at all typical flight Mach numbers."

"Taking design cruise and overload conditions as examples, we analyzed the impact of back pressure changes on inlet performance."

"The results show that the back pressure at the intake outlet has a significant impact on the intake performance, especially during the transition operation of the intake, where there is an aerodynamic coupling effect between the two flow channels."

As Xu Yimin explained, Wang Duoyu stared at the characteristic curves on the display screen showing how the aerodynamic parameters of the air intake changed with flight conditions.

There are many technical projects that need to be developed for turbine-based combined cycle systems, among which intake design is one of the most important directions.

Wang Duoyu had already provided the air intake design drawings before, and in addition to the parallel air intake we are currently discussing, there are several other types.

After Xu Yimin finished explaining, Wang Duoyu also learned about the problems they were currently facing.

He immediately made technical adjustments to address this issue.

Throughout July and into early August, Wang Duoyu spent the entire month of July at the Yuanchang Large Wind Tunnel Laboratory, guiding Xu Yimin and his team in completing numerous technological research and development tasks.

After August 10th, Dawning Supercomputing called, and Wang Duoyu had to go to the old campus experimental building.

The Dawning supercomputing project team has grown increasingly large.

The entire experimental building is the site of the Dawning supercomputing project, and the number of R&D personnel has exceeded one thousand, making it a large-scale project.

In fact, when Wang Duoyu founded Dawning Supercomputing, he was given 8 billion RMB, which was of course a huge investment project.

It started on November 1, 1984, and now it's August 1987, which is almost three years.

The first version of the Dawning supercomputer, which achieved a computing speed of hundreds of billions of floating-point operations, was developed at the end of last year.

The current research and development of supercomputers aiming for a speed of 200 billion floating-point operations per second faces numerous technical challenges.

While it may seem like just an increase of one hundred billion floating-point operations, the technical challenges involved are beyond imagination.

And the most crucial point is the cost!
The Dawning supercomputer, with a speed of hundreds of billions of floating-point operations, costs as much as 80 million RMB just for materials, which is simply unaffordable for most research institutions.

After all, based on the current USD/CNY exchange rate of 3.7, 80 million CNY is equivalent to 21.62 million USD.

Of course it's very expensive.

The RMB exchange rate did not continue to depreciate. In addition to the depreciation of the US dollar, the more important reason is that the foreign exchange department has more foreign exchange reserves and does not need to print more RMB.

In other words, in this current time and space, the domestic export share is barely enough.

With the help of people like Yuan Youlan, Qi Xingbang, and Qiu Xianzhang, companies such as Shanghai Chengtou, Yuexiu Company, and CITIC Securities earned a lot of foreign exchange overseas.

These foreign exchange reserves can be exchanged for oil, minerals, food, technology, equipment, etc., so there is no need to desperately devalue the RMB as in the original timeline to reduce the production costs of domestic export products and increase their competitiveness in the international market.

"Okay, I know the problem. Give me half a day to calculate it."

After Ci Yungui and the others finished explaining their problems, Wang Duoyu said the following.

Inside the meeting room, Lü Xuemin, Hu Shouqiu, Zhou Yukun, Shen Qingxiang, Bao Yuhang, and others all stared wide-eyed.

Although they had been involved in the Dawning supercomputing project for more than two years, they had only met Wang Duoyu a handful of times.

The reason is that Wang Duoyu usually contacts the main project leaders, such as Pang Dianchen, Ci Yungui, and Song Xinwen, and rarely holds a large meeting like today.

Because they didn't have much contact with him, they didn't know much about Wang Duoyu.

Wang Duoyu solved so many technical problems in half a day; he truly deserves to be called an encyclopedic all-rounder. He's amazing!

It's one thing to be a top math whiz, but how come he's also so knowledgeable about other technical challenges?
In reality, Wang Duoyu has said more than once that his technical research and development capabilities in materials are very poor.

At most, he can provide guidance on the technical direction of materials research and development, but if you ask him to develop materials himself, that would definitely not work.

At the very least, he doesn't have the patience to verify each experimental step one by one; that would be too troublesome.

Starting from August 10th, Wang Duoyu was unable to leave the Dawning supercomputing project for five consecutive days.

It wasn't until the 23rd that Wang Duoyu finally finished.

That afternoon, Liu Deben and his group came looking for him, so Wang Duoyu took the opportunity to rest for half a day.

At Harbin Institute of Technology, in the old campus, in the former secretary's office in the administration building, Wang Duoyu and his two companions sat down.

"Duoyu, this is a message from Professor Shang: Goldman Sachs on Wall Street and Sequoia Capital in Los Angeles both want to invest in our Excellence Technology Company."

Upon hearing this, Wang Duoyu's eyes widened in surprise.

"Are they trying to rob us?"

Excellence Technology now offers two products: Powerbook laptops and MP3 players. In particular, the MP3 music player was snapped up by consumers as soon as it was launched.

From May 1st to August, in just over three months, MP3 players have spread to every corner of the United States.

After selling 9.83 million units in May, several million more were sold in June and July, making this product the best-selling product in the North American market this summer, bar none.

In just a few months, it sold 20 million MP3 players, and that was only in the North American market. The amazingness of this product is beyond words.

As a result, Goldman Sachs and Sequoia Capital, two financial giants, immediately became envious.

"It's not robbery; it's just normal business activity."

Liu Deben said:

"I specifically contacted Professor Shang, and he said that while Wall Street capital and Silicon Valley giants currently harbor ill will towards Excellent Technology Company, it is limited to commercial competition."

Upon hearing this, Wang Duoyu looked at Lü Gongliang and asked, "Old Lü, do you think so too?"

Whether it's Goldman Sachs or Sequoia Capital, these two giants are not ordinary capital firms at all.

The former represents Wall Street, and the latter represents Silicon Valley in Los Angeles.

Silicon Valley in the United States is an emerging force in the technology industry, and Sequoia Capital is an outstanding representative of it.

Wall Street needs no introduction; in short, they're not good people.

Lü Gongliang shook his head and said:

"We don't accept investment in the first place because we don't lack funds at all, and we won't go public, so we can simply reject them."

Upon hearing Lü Gongliang's words, Wang Duoyu nodded and said:

"Yes, we do need to turn down these wolves, but with our MP3 players selling so well, these wolves might not be willing to do it willingly."
