this narration is wrong

Chapter 303 Laser Weapons

When Guo Yuan got home and was about to take a shower, his cell phone rang first.

Guo Yuan glanced at the caller ID and found that Director Liu opened it.

"Is there something wrong with the computing power concentration module?" Guo Yuan muttered to himself and made you answer the phone immediately.

"Hey~ Director Liu, is there something wrong with the computing power concentration module?" Guo Yuan asked.

"No, no, your computing power module is very useful. I am entrusted to call you."

"Entrusted by someone?"

"Yes, do you know Cao Bin?"

Director Liu said a name that Guo Yuan would never have thought of.

An idea popped up in Guo Yuan's mind: "Isn't it the second uncle, the King of the Sea, who overturned?"

"Director Liu, Cao Bin is my mother's younger brother and my second uncle. What happened to him?"

"Ahem! It's a bit complicated to talk about. It started about two months ago. When your second uncle was drinking in a bar, he met a half-Chinese boy.

After he had an in-depth communication with this woman, they exchanged WeChat messages. Later, the two of them would go to have a room from time to time, and there was a tendency to develop into boyfriend and girlfriend.

But your second uncle doesn't know that this woman is actually a spy from the United States, and she has been targeted for a long time.

Originally, the comrades here wanted to close the net, but she found your second uncle abnormally, which made the people here feel that there was something wrong, so they stared at it for a while.

Then our comrades here discovered that your second uncle has been studying Gaussian optics and Gaussian beams for so many years. Do you know what these two concepts are? "

Just as Guo Yuan was about to say he didn't know, the voice of the narrator sounded in his mind:

[In 1841, Gauss systematically expounded the imaging theory of geometric optics based on the paraxial approximation, and the result was Gaussian optics named after him. This is one of the earliest optical theories we learn.

As for laser propagation, if the radiation is considered, it will exceed the scope of geometric optics, and the formula needs to be modified to meet the application of wave optics.

The new clear lens formulation treats the laser as a Gaussian beam, that is, a beam with a Gaussian distribution of radial intensity.

Since the output of a normal single-mode laser or single-mode fiber is close to a Gaussian beam, the new formula is applicable over a wide range. 】

To be honest, Guo Yuan didn't understand the narration before saying anything, but Guo Yuan was sure that something that he couldn't even understand must be something very high.

Thinking of this, Guo Yuan said: "Director Liu, I have a certain understanding of Gaussian optics and Gaussian beams, please tell me directly!"

"Okay, then I'll just say it directly, your second uncle's research on Gaussian beams is very important, that's why he's being targeted.

Now that female spy has been controlled by us, your second uncle doesn’t know about it, and is still looking for someone. We hope you can help explain this matter to your second uncle, and then ask your second uncle if he would like to join our research on laser weapons. We hope to get some help from your second uncle. "

"laser weapon?"

"Yes, laser weapons, since Guo Yuan, you have some understanding of Gaussian beams, so I won't need to explain the relationship between the two, and I'll get straight to the point.

You should also know that laser has always been the cutting-edge research of weapons in various countries. Since the 80s, many countries have been developing laser weapons. It is powerful, easy to carry, and low in production cost.

In recent years, the demand for laser weapons in various countries has become more and more urgent. Not long ago, the United States conducted its first tactical high-energy weapon test at the White Sands Missile Test Site in southern New Mexico and successfully destroyed a Katyusha rocket in flight.

This is the world's first laser-based anti-missile system, and we are already a little behind in this regard.

There is an urgent need for technical personnel in this area. "

After listening to it, Guo Yuan suddenly realized that what Director Liu said was really not a secret. There are too many countries researching laser weapons.

"According to the information we have, your second uncle has a deep research on Gaussian circles. I have seen some of your second uncle's achievements on Gaussian circles from others. He has deep insights in this regard."

Guo Yuan was dizzy and couldn't help asking: "What is a Gaussian circle? What does it have to do with a Gaussian beam?"

"Didn't you say you knew?"

"Know a little superficial, half-knowledge."

"It turned out that half a bucket of water was swaying around! Let me explain it to you briefly!

The amplitude distribution of the fundamental mode radiation field emitted by the laser resonator follows the Gaussian function in the cross section, which is the Gaussian beam.

If you want to study Gaussian beams, you must have a deep study of Gaussian functions.

The Gaussian circle is the study of the Gaussian function. "

"So that's the case, okay! Director Liu, I can try to explain it to you, but my second uncle has a bit of an awkward personality. I'm not 100% sure whether he will participate in your research."

What Guo Yuan said is not to say that mathematicians do not participate in the research of lethal weapons.

Perhaps there would be such an idea many years ago, but now scientists hardly have such an idea.

The reason why Guo Yuan didn't guarantee it was really because of Cao Bin's character.

He has a very good relationship with Cao Bin, and he couldn't understand this second uncle very well.

He is a person who is free and unrestrained, unrestrained.

As far as Guo Yuan knows, when his second uncle graduated with a Ph.D., there were many promising jobs for him to choose from.

He chose thousands of options, and finally chose to become a university teacher in a Shuangfeiyiyi. This choice caused a storm in his family at the time.

Relatives in his family took turns to persuade him, but he ignored them.

Director Liu had expected Guo Yuan's answer. He smiled and said, "We all know this. Because of this, we think you can only help explain this matter, and at the same time explain the situation to him. It's up to him whether your second uncle wants to follow up. We won't force him."

Guo Yuan said "hmm" to show that he knew.

"Then I will trouble you." After speaking, Director Liu hung up the phone.

After Guo Yuan put down his phone, he collected his thoughts and dialed his second uncle's number.

"Drip~ I'm sorry, the number you dialed is busy, please try again later." The other side hung up in seconds.

Guo Yuan frowned. Just now he heard from Director Liu that his second uncle wanted to develop a boyfriend and girlfriend relationship with this mixed-race woman. He wouldn't be really tempted, would he?
Guo Yuan dialed again, but the phone hung up again.

After dialing more than ten times in a row, Cao Bin finally answered the phone.

"Who is it, are you bothering?" Cao Bin's voice was a little annoyed.

"It's such a disappointment. I'll take a shower first, so you should deal with it quickly." A charming female voice faintly came from the other end of the phone.

The corner of Guo Yuan's mouth twitched, he misunderstood, Neptune has no heart.

"Second uncle is me." Guo Yuan hurriedly reported his family name.

"Why are you calling me?" Cao Bin was very upset when his good business was interrupted.

"Second uncle, I have business to see you."

"There is something to say, there is fart."

Guo Yuan thought for a while and felt that he couldn't get straight to the point. He asked tactfully, "Second Uncle, do you have a dream?"

"You idiot!" Cao Bin hung up the phone with a dark face.

The corner of Guo Yuan's mouth twitched, he thought about it and directly transferred 1 yuan to Cao Bin.

Cao Bin received it in seconds.

After 10 seconds, the phone rang.

Guo Yuan picked up the phone.

"Hey, my dear nephew, if you have something to say, how can I give you money!"

"It's nothing, I just want to chat with you, second uncle, why did you give up your high-paying job to become a university teacher?"

"It's very simple. I don't want to take exams with other people. I hate doing exams with others. I was disgusted when I was studying. Why do I need to take exams after graduation? Just find a job that pays more and has less work close to home."

"That's it?"

"That's it!"

"Um, do you usually study mathematics?"

"Yes, I often study stocks and occasionally study number theory."

Hearing Cao Bin's words, Guo Yuan was a little surprised. He knew that Cao Bin studied stocks, but he didn't expect Cao Bin to study number theory.

Guo Yuan has heard a sentence a long time ago: The biggest pitfall in the mathematics world is led by number theory.

The prime numbers in number theory are one of the biggest pitfalls.

Twin primes, Mersenne primes, Orsonian primes, the minimum interval of prime numbers, and the maximum interval of prime numbers all belong to the category of prime numbers and are also difficult problems in the world.

In addition to prime numbers, there are also Goldbach's conjecture and Riemann's conjecture, especially Goldbach's conjecture, known as the world's three major conjectures.

If prime numbers are the biggest pitfalls, then these two problems are god pits.

The prime number is to let you go in and you can't get out, and these two problems are that you want to die when you go in.

Do you want to go in but not get out, or do you want to die when you go in?It's all in your mind.

"Second uncle, why do you want to study scolding? Aren't you afraid of falling into the pit?" Guo Yuan asked.

"Number theory is a pit because it is difficult, but it is also the easiest field to gain status, reputation and awards.

Any conjecture in it can make people famous all over the world. If you can solve Goldbach's conjecture and Riemann's conjecture, either of these two problems, you will definitely win the award, and the Fields Medal will chase you and give you an award.

I thought that if I could research something, wouldn't it be possible to get fame and fortune and just lie flat, without having to work hard at all? "

Guo Yuan was a little helpless when he heard the words, which really fit Cao Bin's character.

"Then second uncle, have you researched anything?" Guo Yuan continued to ask.

"No, I have tried a lot, such as Kakutani conjecture, ABC conjecture, Zhou's conjecture, Beal conjecture, and list coloring conjecture. I have tried all of these, but nothing has been researched."

Guo Yuan heard the words and thought: "It seems that the second uncle still has a B number, and he didn't start with the eight conjectures."

Although Guo Yuan is a layman in mathematics, he has heard of the eight conjectures. If anyone can challenge the eight conjectures alone and prove one of them, then Guo Yuan will definitely not believe it.

Because the mathematics world has the most geniuses in the world, and they all want to prove the eight conjectures.

But for hundreds of years, only one conjecture has been proven successful.

That is, the British mathematician Andrew Wiles proved Fermat's last theorem in 93, and it is said that the process was also very tortuous.

It can be seen from this that the difficulty of the eight conjectures,

Few people in the mathematics world spend a lot of energy on researching these.

After talking so much, Guo Yuan has a certain understanding of the general mentality of his second uncle and the direction of academic research.

He changed the subject and said, "Ahem! Second Uncle, I was actually entrusted to call you today."

"I knew that you would go to the Three Treasures Hall if you have nothing to do. If you have something to say, hurry up, I still have something to do here!"

"Did you often have sex with a half-race beauty a while ago?"

"Nothing! Don't you know me yet? Me. Ding Dong!" Before Cao Bin finished speaking, he received the "evidence" found by 01 on WeChat.

With the evidence in front of him, Cao Bin cleared his throat and said, "Ahem, ahem! Well, there is indeed such a thing, but she said she wanted my house a few days ago, and I have already dumped her. You know my rules, anyone who wants to contact my family will be cut off immediately."

"Do you know that the purpose of this woman approaching you is not pure?"

"I know! She's greedy for me."

"Wrong, people are not greedy for your body, they are greedy for your other things. I have received news from here." Guo Yuan told Cao Bin what Director Liu told him.

Cao Bin was dumbfounded after hearing this.

"Guo Yuan, are you serious?" Cao Bin asked after a long silence.

"I don't joke about this kind of thing."

"I'll wipe it!" Cao Bin hung up the phone after an exclamation.

He put on his clothes and ran straight from the hotel room.

After half an hour, Cao Bin, who had locked the door at home, called Guo Yuan.

"Guo Yuan, who told you these things?" Cao Bin asked seriously.

"Second uncle, can't you think of it yourself?"

"In that case, the higher-ups have taken a fancy to my research on Gaussian beams, right?"

"Yes." Guo Yuan affirmed Cao Bin's guess.

"They want me to help?"

"Well, they want you to help research laser weapons, but I didn't directly agree to help you."

Cao Bin pondered for a long time and said, "Will it be beneficial if I help?"

"Sure! Your superiors won't let you work in vain."

"I want a senior title?"

"This shouldn't be a big problem, why don't I give you the phone number and you go get in touch?"

"Wait! Guo Yuan, tell me the truth, how is your relationship with the boss?" Cao Bin asked.

"Very good, we have cooperated on many projects." Guo Yuan replied.

"That's it! Then give me your phone number! I might pull your tiger skin as a banner at that time, don't you mind?"

"I don't mind if you use my name as you like."

"Okay! Then I'll talk to them." After finishing speaking, Cao Bin hung up the phone.

It was the second day that Guo Yuan got news from Cao Bin again.

Cao Bin sent him an email, saying that he had been transferred overnight, and his superiors promised him that he would be given a deputy senior title after helping to develop laser weapons this time, and a senior title in five years.

Cao Bin needs to sign a related confidentiality agreement and cannot disclose the content of the experiment.

This research may last for about a year, and Cao Bin entrusts Guo Yuan with the task of comforting his parents, that is, Guo Yuan's grandfather and grandmother.

Guo Yuan's expression was a little helpless, Cao Bin left him a mess before leaving.

Guo Yuan speculates that the reason why Cao Bin is willing to continue this job is most likely because he has the idea of ​​working hard for a year and completely lying down for the rest of his life.

After a year of hard work, he will become an associate professor, and after 5 years he will become a professor. He really doesn't need to work hard anymore, which fits Cao Bin's personality very well.
