The passionate years starting from the college entrance examination

Chapter 360, Choice and Meeting (Please subscribe)
May of 1970 was definitely a turbulent month.

In the global electronics market, many stockholders on the New York Stock Exchange cried miserably because of an announcement by the electronics giant China Resources.

There are many people waiting in line at some high-rise buildings on Wall Street.

Because the stock price of Donald Duck Technology Company plummeted, gamblers who used leverage to win a lifetime of wealth were immediately outraged.

If the stock account is liquidated, the position will naturally be forced to be liquidated by the financial company.

Then the stocks in the hands of gamblers become useless paper.

At first, I listened to the analysis of financial companies or financial experts in newspapers, or I believed in relevant professional comments sent by PHS mobile phones and pagers.

As a result, Donald Duck Technology's stock price is now like an avalanche, causing everyone to suffer heavy losses. Who should be responsible for this?
Investment is risky and you need to be cautious when entering the market. This cliché has probably been forgotten by gamblers for a long time, right?
Comrade Tang Dake is no longer the boy he was before. He has grown into a qualified capitalist, so he doesn't care at all about the gamblers lining up in high-rise buildings waiting to jump off the building.

After all, these gamblers definitely know that investment is risky before investing, but no matter how great the risk is, they cannot stop them from increasing leverage.

If that's the case, isn't everything already doomed?
Whether the gamblers succeed or fail, it is their own choice and has nothing to do with Comrade Tang Dake himself.

But now he just wants to be quiet and doesn't want anything else.

With three billion US dollars in hand, he can return to the top no matter what he does next.

Now he has three options. The first is to buy Donald Duck Technology Company at the bottom and lead the company back to the top.

However, Comrade Tang Dake does not have such confidence, just because in the past eight years, he has witnessed the terrifying strength of China Resources' undefeated myth.

He has experienced it firsthand. Starting from the summer of 1962, he was the first agent for electronic products of China Resources Company. He earned more than 2.4 million US dollars in one fell swoop and opened up a new career for the then 16-year-old boy. world.

From 1962 to 1970, eight years have passed.

In the past eight years, China Resources has successively launched Huayue calculators, Huaxin radios, "Ping Pong" game arcades, home version game consoles, Huaxing digital SLR cameras, electronic dictionaries, Huashuo computers, pagers, and PHS mobile phones. and other electronic products.

There is no doubt that these electronic products are all money-making tools that lead the trend of the times.

With such a powerful company, Comrade Tang Dake is not confident in competing with the other party.

Just like this time in the mobile phone competition, he was full of confidence from the beginning. However, after cooperating with IBM, especially after learning about the labor costs on the Bay Island, Comrade Tang Dake's despair began to spread. .

why?
Because their Donald Duck mobile phone was developed by relying on the low-cost Bay Island labor market and North American R&D team. Even so, the cost of each Donald Duck mobile phone is only eighty-nine US dollars.

And what about China Resources’ PHS mobile phone?

The cost is definitely lower than eighty-nine dollars, not to mention that they have been selling it for four years, the cost is absolutely ridiculously low.

Thinking of this, Comrade Tang Dake couldn't help but feel chilled in his heart, but he didn't say it out loud, but he had already planned Jin Chan's escape from this moment.

During a gathering with small capitalists like the Schoolcraft family, Comrade Tang Dake was suddenly inspired and decided to list Donald Duck Technology Company.

Only by going public can he get out of the quagmire.

Therefore, now that he can get rid of the quagmire of Donald Duck Technology Company, whether to save it or not, or whether to turn back is a matter of his own thoughts.

But every time he thought of the terrifying China Resources Company, he hesitated.

The first choice made him unable to make up his mind, while the second choice was that his father had already told him to go back and inherit the family business.

Speaking of which, his major in college was real estate. Unfortunately, he didn't even take a few days of classes.

Therefore, in his opinion, it is better to start his own business than to inherit the family business.

That he was able to turn his own wealth into three billion dollars in cash in just eight years is the best proof of his smart brain and the current good times.

He has proven his worth and no longer needs to take over the family business.

The third option is to start a new business by himself, and he is currently more inclined to this option.

There are still many opportunities in North America, such as the highly competitive retail market.

In Comrade Tang Dake's view, there is definitely a lot of potential for retail companies, but he is not very familiar with this industry. If he enters rashly, he is afraid that he will have to pay tuition and even lose the three billion US dollars in his hands.

North America is a continent where anything can happen.

Therefore, Comrade Tang Dake will be very cautious when investing.

"Well, Donald Duck Technology Company still has more than two billion US dollars in cash. What should we do with this money?"

Suddenly, Comrade Tang Dake thought of the money again, maybe he should think of a way.

As for the 1.5 billion US dollars he borrowed from shares of Donald Duck Technology Company, to be honest, he had no intention of repaying this money from the beginning.

When the contract was signed, it was already written very clearly in the contract.

When the stock price rises to a certain level, certain procedures will be triggered.

For example, if the stock price rises by 15%, then the loan from First Citibank will automatically become a sales contract.

On the contrary, once it falls to 40%, the loan will be forcibly withdrawn.

First Citibank was taking advantage of the situation, while Comrade Tang Dake was just following the situation.

That's why we were able to reach a cooperative relationship with a 'tacit understanding'.

In fact, not long after the loan ended, Comrade Tang Dake took the initiative to have the sales data of Donald Duck mobile phones released, helping the stock price of Donald Duck Technology Company to rise.

At that time, Donald Duck Technology was at its peak.

Therefore, in a very short period of time, the stock price exceeded the 15% increase in the contract, and the loan contract suddenly turned into a sales contract.

Although this is unreasonable and illegal, for capitalists, even illegal things can be made reasonable and legal through means.

However, even Citibank No. 1 did not expect that the contract would become a hot potato before they even had time to change hands.

Because China Resources Company's reaction was so fast, the announcement was made at once, and then it quickly spread to North America, causing the stock price to halve in a short period of time.

And it didn't take half a day to cut the speed to 40%.

In this way, not long after such a loan contract turned into a sales contract, it immediately turned into waste paper.

Not good!

Even if First Citibank holds 20% of Donald Duck Technologies, so what?
Comrade Tang Dake dared to cheat First Citibank because he was sure of the greed of the other party, and this was an unspoken rule allowed by Wall Street. If First Citibank wanted to cause trouble for Comrade Tang Dake, then things would break out. Come out, I'm afraid it won't be comfortable for anyone.

Anyway, Comrade Tang Dake is just one person, so of course he is not afraid, but First Citibank has to consider the impact.

However, after all, it is 1.5 billion US dollars, which is not a small amount of money.

How Comrade Tang Dake will overcome this difficulty depends on the follow-up.

Chen Guohua didn't know about things in North America. He was still in a meeting at this time.

If Moscow wants to launch a space cannon, the mainland will have to guard against it.

As a result, before the matter was finished, news came back from Washington that North America was also going to do it, and they were even more ruthless.

Particle beams, electromagnetic guns, laser cannons and other futuristic sci-fi weapons have all been approved.

Chen Guohua was speechless when he learned that there were so many things going on in North America.

Vladimir Chelomei's plan to develop a space cannon is already outrageous. Unexpectedly, North America's von Braun, Armour Busroyd, and Bernard Brody were even more unreliable and directly initiated projects such as particle beams and other horrific things. Son.

At that time, Chen Guohua wanted to say, otherwise labor and management would also come up with a two-way foil.

As a fool, if you want to brag, it seems that Chen Guohua can't do it.

Anyway, the nerves in the mainland are tense because of the very frightening weapons that Chelome and others have come up with.

But Chen Guohua couldn't comfort them. After all, he was not sure whether Vladimir Chelomei would build a space cannon in his lifetime.

If it is really built, you will have to guard against these horrible things, which will be quite troublesome.

In the conference room, Chen Guohua didn't say a word, just listened to Qiu Zongyue and other leaders talking.

Anyway, nowadays, intelligence is not so easy to obtain. All we can say is to take our time and pay close attention to the situation in Washington and Moscow.

"Guohua, why haven't you spoken? Have you thought of any solution?"

While Chen Guohua was thinking silently, a leader suddenly turned his attention to him, which immediately attracted the attention of other leaders.

"That's right, Comrade Guohua, why don't you say a few words and give your opinion? We old guys all need to hear the opinion of your expert."

Other leaders also spoke. Chen Guohua forced out a smile and pretended to be relaxed:
"Dear leaders and comrades, in fact, the leaders have already said the same thing, especially Dean Qian. What he said is very reasonable. We don't need to worry. Although we built intercontinental missiles a few years later than them, we We will definitely not be behind them in space cannons and other weapons.”

"Of course, I also want to say one thing here, that is, the leaders seem to have forgotten that our greatest advantage is actually defense."

defense?

These words immediately left many leaders Zhang Er Monk scratching their heads. Some leaders instantly understood what Chen Guohua meant and smiled immediately.

In fact, the air defense system that Chen Guohua had proposed in the past few years has actually been completed a lot during the construction and advancement in these years.

For example, interceptors, etc., such as command and control systems, etc.

Of course, the command and control system still lacks a lot, because there is no corresponding algorithm talent, so there is still a certain gap in achieving very accurate and quick response interception.

In modern society, intercontinental missiles, a major killer, can only have an interception rate of more than 90% in the early stages.

Even if the air defense system established by Chen Guohua, no matter how powerful the algorithm is, it still needs a powerful enough interceptor to intercept the enemy's intercontinental missiles at an early stage.

If the enemy also develops such an intercontinental missile by referring to Qian Xuesen's ballistics, it will also be a huge threat to the mainland.

Therefore, in terms of air defense systems, one is to improve the algorithm program to detect and intercept all enemy missiles as early as possible.

On the other hand, it is to increase the flying speed of the interceptor. For example, if the interceptor can fly at a speed of Mach 20, or even Mach 25 or 30, then there is no doubt that it will be able to successfully destroy all the enemy's missiles. Get intercepted.

But at such a speed, it is too difficult.

After all, being able to achieve such a flying speed also means that the speed of intercontinental missiles will break through to even greater speeds.

In this case, it is definitely a dimensionality reduction blow to the enemy.

When Chen Guohua mentioned the air defense system, the leaders' eyes suddenly lit up, but soon some leaders raised questions:
"But weapons such as space cannons and particle beams are launched from space. Can our air defense system successfully intercept them? And when people directly hit the satellites in our space, won't our air defense system have to change? Becoming blind?"

The air defense system also includes related communication systems such as geostationary satellites, and phased array radars on the ground.

Therefore, the problem mentioned by the leader immediately made other leaders stop smiling and stared at Chen Guohua, hoping that the latter could come up with a better solution.

"Leader, the problem you mentioned is actually based on the fact that the other party has developed a space cannon in advance, and it must be able to successfully hit the cannon shells."

After a pause, Chen Guohua continued:

"The development of space cannons takes time, and we will not stand still. So at this stage, we still need to continue to promote the construction of our air defense system."

"Secondly, they want to develop a space cannon. I think we can also establish such a weapons project. I have several ideas. The theoretical basis at the technical level can also be improved from multiple levels such as physics, mathematics, and materials science."

Hearing this, the leaders present all sat upright, and their originally dim eyes suddenly brightened a lot.

Qian Xuesen and several other weapons experts also cast interested glances. After all, they were all very aware of Chen Guohua's strength, although the latter had nothing commendable in terms of weapons.

However, Chen Guohua's strong mathematical ability and technological innovation ability are enough to defeat everything in an instant.

"We must first understand a concept, what is a space weapon?"

"As weapons used in outer space operations, space weapons specifically refer to weapons that specifically attack enemy aircraft, satellites or ballistic missiles operating in outer space. They can be roughly divided into kinetic energy weapons and directed energy weapons."

As soon as Chen Guohua opened his mouth, he gave a conceptual and concrete definition of space weapons, and even classified them, which immediately shocked the leaders.

It turns out that Chen Guohua’s thinking about space weapons has reached this point?

terrible!
No wonder he proposed the Nantianmen Space Station plan. Perhaps the mainland's technological strength is really not enough to support a moon landing, so he will promote the mainland's aerospace technological strength step by step.

Otherwise, if Chen Guohua directly brings out these extremely advanced technologies, and everyone supports such a plan, wouldn't it drag the mainland into an endless abyss?
After all, you still have to keep your feet on the ground.

Whether it is Moscow or Washington, they may know some of the sketches and designs of space weapons, but at the theoretical level, Chen Guohua thinks further.

"Washington has established a project called a laser cannon. In fact, this can be said to be a laser cannon or a laser gun, because at this point in time, most people in North America only have such an idea."

"As a directed energy weapon, whether it is a laser gun or a laser cannon, although its speed is the speed of light and does not need to be used in advance, the laser is easily affected by the weather, so it has great limitations."

"If it is used in outer space, there will naturally be no restrictions in these aspects, but there is a big problem, that is, to develop such a laser weapon, the technology and talents required are absolutely unimaginable. Astronomical numbers”

With Chen Guohua's science popularization, everyone in the office held their breath, and no one dared to disturb Chen Guohua.

"The technology of laser weapons is actually very simple. That is superconducting technology. Only by creating superconducting energy storage devices and storing super-intensity current can we produce high-intensity lasers. Only in this way can we destroy enemy satellites or missiles. .”

"We at Zhenhua Research Institute have also had ideas about superconducting memory technology that can store ultra-high currents, but we have not put it into action."

Hearing this, Qiu Zongyue couldn't help but interject:

"Guohua, why didn't you tell me earlier? You said, at least we can discuss it. It shouldn't be too late now, right?"

Except for Qiu Zongyue, Qian Xuesen also spoke up and expressed his curiosity:

"Yes, Director Chen, if I remember correctly, does your Zhenhua Research Institute have a laboratory that specializes in laser research? Can such a laser weapon be built?"

hiss!
Following Qiu Zongyue and Qian Xuesen's questions, everyone in the office took a deep breath. They were shocked, but also had happy expressions on their faces.

Because this shows one thing: Zhenhua Research Institute definitely has relevant technical reserves, but it’s just that it’s not time for technological breakthroughs yet.

In the lithography machine project in the early years, Zhenhua Research Institute has developed lasers such as aluminum gallium arsenide semiconductor lasers and excimer lasers.

Although everyone does not know much about technology, and may not know the difference between these lasers and the laser weapons Chen Guohua just mentioned, but everyone can have a clear understanding:

That is, Zhenhua Research Institute has conducted a lot of research on lasers in the early years.

Especially the extreme ultraviolet lithography machine project that has been approved a few years ago. This project is also a gold-eating beast. Many leaders here are deeply impressed by this project.

Leaders are very concerned about money-burning projects.

Because before the project was established, Chen Guohua had already said how these projects would help the mainland, and what changes the final scientific research results of these projects could bring.

This is why leaders approved the project.

Although Chen Guohua is the number one person in the domestic scientific community, he cannot cover the sky with one hand. He does not need to tell his superiors about anything and can do whatever he wants. This is definitely not the case.

It's like a company, with the chairman, president, vice president, financial director and other senior executives. When these people work together, they can't always do whatever the chairman wants, right?

Always ask the president and other management if this can be done, if there are any difficulties, etc.

It's impossible for the chairman to say that he wants to turn the company into a Fortune 500 company. People like the president can already do it, right?

"Leader, do you still need me to answer this? It's like I told everyone back then that the moon landing plan is not advisable and the space station project is the most suitable for us. What's the result?"

Chen Guohua's words immediately made Qiu Zongyue hide his face in shame and immediately shut himself up.

Even other leaders and scientific researchers like Qian Xuesen are equally ashamed.

Several leaders even glared at Qiu Zongyue, seeming to blame him for asking such irrelevant questions when he had nothing to do.

Fortunately, Chen Guohua quickly looked towards Qian Xuesen and said with a smile:

"Dean Qian, the lasers created by our Zhenhua Research Institute are the laser guns I just mentioned. They are not very lethal. As for being used as space weapons, to be honest, it is even more impossible."

There is really not much to say about the related laser accessories that were extended by the lithography machine project led by Chen Guohua.

"As I said before, laser weapons have many advantages. They don't need to be advanced. They shoot in a straight line at the speed of light. The delay is completely negligible. There are no curved trajectories. In addition, there is no recoil. They can quickly move to attack targets, and they can also perform single-shot attacks. shot, multiple shots or continuous fire”

"But the difficulty of developing laser weapons is really too high. Otherwise, I would have established the project long ago."

"Our Zhenhua Research Institute has a generator set and power transmission equipment laboratory. This laboratory has a subdivided laboratory called the UAV Battery Research Laboratory."

When Chen Guohua mentioned this battery research laboratory, everyone looked curious.

Chen Guohua will never suddenly mention this matter. The battery is definitely related to laser weapons. It should be the superconducting energy storage device that Chen Guohua just mentioned.

"If our battery technology can make a qualitative leap, then we can develop an energy storage device for our laser weapons."

"Whether it's a drone, a laser weapon, or other equipment, we all hope to develop a device with high energy density, small size, light weight, fast charging, long life, and no waste gas or waste. battery."

As long as there are such batteries, mainland drones can achieve decisive victory in ground wars.

And with such a battery, laser weapons, or many technological equipment can be applied.

For example, electric motorcycles, mobile phones, electric fans, new energy vehicles, etc., among many modern technological equipment, almost all are related to electricity.

Therefore, at this time, if the mainland can develop such a battery, it is really invincible.

After hearing Chen Guohua mention this, the leaders realized that the Zhenhua Research Institute turned out to be so excellent, it was really a crouching tiger, hidden dragon.

That's it. Chen Guohua had been shouting slogans such as "no one" and "poor" before. He was really 'shameless'!
Qian Xuesen and others all cast resentful looks at Chen Guohua: Your Zhenhua Research Institute is already so outrageous, why are you still so humble? And you always compete with other scientific research institutions for people?
Excessive!

Chen Guohua pretended not to see such a look.

Many resources, if you don’t take the initiative to fight for them, will definitely be taken away.

To be honest, if possible, Chen Guohua would also like to be a salted fish, but many times, people cannot help themselves in the world.

Since you are in the game, you must consider the actual situation.

"In fact, whether it is a laser weapon, an electromagnetic weapon, or an electromagnetic catapult, their energy storage device can be said to be a battery."

Chen Guohua went into detail this time. It can be said that he explained many surreal weapons very thoroughly.

Starting from laser weapons, to electromagnetic guns, and then mentioned electromagnetic catapults and so on.

The leaders were all shocked. It turned out that there were so many opinions on space weapons, or weapons of the future.

For example, the femtosecond-level super-powerful laser device mentioned by Chen Guohua uses a low-power laser blinding weapon.

It can be equipped on tanks, etc. to develop a laser suppression and sighting system. This system consists of a main control computer, a laser transmitter, a thermal imager and a jammer, and is directly installed on the rotating platform at the left rear of the tank turret.

This kind of equipment can continuously emit blue-green lasers with a power of about one hundred megajoules, which is powerful enough to burn the retinas of enemy soldiers two kilometers away, or directly cause damage to the opponent's optoelectronic equipment.

"We can even make technological improvements and develop eight kilometers, or about five hundred kilometers."

Hearing Chen Guohua mention this equipment, it seemed that the technology had been developed, which immediately made the leaders' breathing quicken.

"Guohua, if the project is approved now, how long will it take for you to develop it?"

An impatient leader couldn't wait to ask, but he saw Chen Guohua spreading his hands with a very helpless expression:

"Leader, the best I can do is to improve the theoretical level first, and then slowly derive the technology. But as for when it will be developed, I don't know. I still need to be responsible for the Nantianmen Space Station project."

The leaders in the office immediately sighed.

Chen Guohua has too much burden on his shoulders, and many projects cannot do without him.

At this point, the leaders were worried that he would be exhausted.

If it weren't for Chen Guohua's frequent physical examinations by several doctors from the Health Bureau, and Chen Guohua himself is not yet thirty years old, he has always been in good health and has no disease at all.

Even if he has symptoms such as cold and fever, Chen Guohua has very few symptoms.

The few times his daughter-in-law Yu Moli cured her, no one else was needed.

Not to mention that there is a small hospital within the Zhenhua Research Institute, which also has many doctors with excellent medical skills. Even doctors from the Health Bureau come to the small hospital from time to time for consultation or study.

Perhaps even Chen Guohua himself knew that he was responsible for too many tasks, so he didn't mention these things.

However, for these projects, even if other people were asked to come, they would probably just look at them with indifference.

"Okay, let's not mention the project establishment for now. Let me tell you a brief introduction."

Seeing that the atmosphere in the office was a bit dull, Chen Guohua smiled and said.

"Essentially speaking, laser weapons actually use beams to deliver huge capabilities, interact with the target's materials, and produce different killing and damaging effects, such as ablation effects, shock wave effects, radiation effects, etc., so relying on these With miraculous abilities, laser weapons are extremely ideal space weapons.”

"There are probably only so many laser weapons. Next, let's briefly popularize particle beam weapons."

Particle beam weapons are a concept weapon manufactured using the principle of particle accelerators. There is no need to say more about this thing, because there are accessories such as electron linear accelerators in the manufacturing process of atomic bombs.

The electron linear accelerator is actually a charged particle accelerator, so this principle is simple, and everyone in Moscow and Washington knows it.

Even countries like Great Britain, Tokyo, and Gallic Chicken know this stuff.

Of course, knowing it does not mean that they will definitely be able to think of this, let alone build such a particle beam weapon.

Therefore, when Chen Guohua mentioned particle beam weapons, Qian Xuesen and Qian Sanqiang both showed thoughtful expressions.

The principle is very simple. After the charged particles enter the accelerator, they will be accelerated to the required speed under the action of the strong electric field force. At this time, the particle beam will be emitted, which will produce huge lethality.

The high-energy particles emitted by particle beam weapons travel at a speed close to the speed of light and are used to intercept various spacecrafts. They can hit the target in a very short time, and generally there is no need to consider the shooting advance.

Therefore, a particle beam weapon highly concentrates huge energy into a small area in the form of a narrow beam. It is a weapon that kills point targets. Its high-energy particles violently collide with the molecules of the target material, generating high temperature and heat. Stress causes the target material to melt and damage.

Therefore, there is nothing good to say about particle beam weapons.

But this thing is also one of the weapons that leaders want to develop, and several leaders have even recorded it.

Given their status as leaders, they took the initiative to record these weapons. This was not because they were diligent and studious, but because they were really shocked.

They need to write it down so they don’t forget.

"There are also microwave weapons, let alone weapons like this."

"Guohua, slow down a little, the microwave weapon you are talking about is"

One leader didn't react for a while because he was busy recording the particle beam weapon, so he didn't hear clearly.

Chen Guohua had to reiterate that microwave weapons are actually composed of an energy system, a high-power microwave system and a transmitting antenna. They mainly use high-power microwave beams with directional radiation to kill and destroy targets.

Microwave beam weapons have strong all-weather combat capability, long effective range, and can kill several targets at the same time.

In particular, it is entirely possible for microwave beam weapons to be compatible with radars to form an integrated system, which can first detect and track targets, and then increase the power to kill targets to achieve the best combat effectiveness.

"So microwave beam weapons are like invisible divine whips. They can not only cause comprehensive damage and sweep across enemy electronic equipment, but also carry out precise strikes and directly hit the enemy's information center."

After a pause, Chen Guohua continued:

"It can be said that microwave weapons are indispensable basic weapons for modern electronic warfare, electromagnetic warfare, and information warfare."

In the following time, Chen Guohua talked a lot about space weapons.

Including anti-satellite kinetic energy weapons, orbital guns, quantum radars, air-to-ground missiles, space station cannons, nanosatellites, etc., the popular science of each weapon has left leaders stunned.

They didn't expect that there were so many different types of space weapons, which simply refreshed everyone's understanding.

What everyone didn't expect was that Chen Guohua knew so much about this so-called space weapon.

After Chen Guohua finished speaking, the leaders asked him which weapon he had planned?

Sometimes, having too many choices is not a good thing. It is called difficulty in choosing.

If possible, of course the leaders hope that they can all launch the project together, but this is impossible because Chen Guohua is only one person and he is now too busy, let alone leading this space weapons project.

In addition, the current financial situation in the Mainland is not abundant, and it can even be said that it is stretched.

According to Chen Guohua's suggestion, laser weapons are the best choice, and other projects such as quantum radar and air-to-surface missiles can be established first and studied slowly.

Radars and missiles are both readily available, but to specifically turn them into quantum radars and air-to-surface missiles, further research is needed.

For example, quantum radar is bound to have something to do with quantum mechanics, and like the quantum entanglement transmission technology mentioned by Chen Guohua before, it is still necessary to improve the relevant theory before we can conduct technical research.

Of course, Chen Guohua can take it out directly, but the problem is the shortage of talents.

In short, there are many things I want to do, but due to various reasons, I have to focus on the most important things at the moment, and other things can be taken slowly.

"Director Chen, can you talk to me about quantum radar?"

After the meeting, what Chen Guohua didn't expect was that Li Zhengdao actually followed him and called him.

Since the latter returned to the mainland, he has been doing scientific research at the Institute of Physics of the Beijing Advanced Institute of Science.

As one of the top leaders in the world of physics, Li Zhengdao's research results at the physics level are very impressive.

In fact, he has been interested in the subject of quantum mechanics for a long time, but because of his own identity, he has always been cautious.

However, the leaders have great trust in him.

For example, in this meeting, I asked him to come and participate together.

Li Zhengdao has participated in several such meetings, and gradually understood why the mainland's scientific research results have advanced so rapidly in recent years.

In addition to Qian Xuesen and other returned overseas students and professors studying abroad, the most important thing in the mainland is Chen Guohua, the number one person in the mainland's scientific community.

It can even be said that if it were not for Chen Guohua, the mainland's scientific research results may have been set back ten or twenty years.

"No problem, Professor Li. I'm going back to Zhenhua Research Institute. Let's talk in the car?"

"Okay!"

As soon as Li Zhengdao finished speaking, another voice came from behind him.

Without even looking back, Li Zhengdao knew that it was Yang Zhenning's voice.

Regarding the latter, Li Zhengdao has very complicated feelings. Anyway, he should try not to cooperate with the other party as much as possible.

Otherwise, every time you argue about the order of signing papers, it will affect your mood.

"Director Chen, do you mind adding me?"

Seeing Yang Zhenning joining in the fun, Chen Guohua couldn't help but smile and nodded in agreement.

Anyway, he doesn't mind, and even if he does, he won't say it to his face.

You know, he originally persuaded Yang Zhenning and Li Zhengdao to return to the mainland, but now he refuses to communicate with them. This is very hurtful.

So, in the car, Long Kanghou drove himself and drove Yan Shouchun to other cars. Two cars in front of him and one behind him sandwiched Chen Guohua's car in the middle.

Chen Guohua took the initiative to sit on the co-pilot and turned around to chat with Yang Zhenning and Li Zhengdao about quantum radar.

In fact, the two of them have quite a lot of theoretical research on quantum mechanics, but they are still very different from the idiot Chen Guohua.

"Quantum radar is mainly divided into three categories. First, quantum radar emits entangled quantum state electromagnetic waves. Its detection process is to use pump photons to pass through the crystal through parametric down conversion to generate a large number of entangled photon pairs. The polarization between each entangled photon pair The states are orthogonal to each other, dividing the entangled photon pairs into detection photons and imaging photons."

"The imaging photons are retained in the quantum memory. The detection photons are emitted by the transmitter and reflected by the target, and then received by the quantum radar. The entangled correlation between the detection photons and the imaging photons can improve the detection performance of the radar."

"The second is that quantum radar emits non-entangled quantum state electromagnetic waves. The transmitter emits the signal photon in the entangled photon pair, and the 'backup' photon remains in the receiver. If the target reflects the signal photon back, then by pairing the signal photon and Entanglement measurement of 'backup' photons enables target detection."

Listening to Chen Guohua's introduction, Yang Zhenning and Li Zhengdao nodded from time to time, and they couldn't help but admire the former in their hearts.

Obviously Chen Guohua is a world-famous mathematician. He can be said to be the current emperor of mathematics in the world, and even the number one person in the world of mathematics.

But no one expected that Chen Guohua's research on the physics level would be so in-depth, which is simply terrifying to the extreme.

In the past, Chen Ning Yang and the others had also come into contact with von Neumann, who was also a very awesome mathematician, computer scientist, physicist and chemist, as well as a very versatile super scientific researcher.

At the same time, von Neumann's research on the mathematical level is comparable to that of Kolmogorov in Moscow, but his research results in the fields of computers, physics and other fields are also very impressive.

Unexpectedly, Chen Guohua was much more powerful than von Neumann.

This is probably the difference between genius and super genius, right?

Although Yang Zhenning and Li Zhengdao are usually very humble, they know that their scientific research results are great.

However, after comparing Chen Guohua, it is inevitable to feel helpless that people are more irritating than others.

"Third, the classical electromagnetic waves emitted by radar."

While Chen Guohua and Yang Zhenning were talking about quantum radar, far away in New York, North America, PHS mobile phones began to kill everyone. At the same time, Big Brother and Big Mobile phones also had to deal with this wave of price wars.
