From a university student to a chief academician

Chapter 66 Must Be Ye Fei (4000 words)
"Research on laser weapons?" Ye Fei's brows furrowed for a moment, his eyes flickered, showing a hint of hesitation.

His Gaussian circle has just begun to be studied, and the first problem is only halfway through.

If he were to study laser weapons at this time, he would have to suspend the research on the Gaussian circle, and he didn't want to suspend it.

Moreover, I have just become a teacher not long ago, and I still have students to take care of, so I have to leave the students to study laser weapons at this time.

It is irresponsible to the students to leave before the class is finished.

"Is there any problem?" Professor Yang looked at Ye Fei hesitatingly, he pursed his lips tightly, stared straight at Ye Fei, and asked a little nervously: "If you have any problems, you can tell them, and I will solve them for you. If you can't solve it, I will find a way to solve it for you."

Seeing Professor Yang's uneasiness, Ye Fei felt a little sorry. He exhaled lightly and asked, "Professor Yang, is it because I am going to study laser weapons that I am going to leave Zhonghu University and go to Kyoto University of Technology?"

"Yes!" Professor Yang nodded, "You have to go to the laser laboratory of Kyoto Institute of Technology, otherwise you won't be able to conduct research."

Ye Fei shook his head slightly, and regretfully said, "Professor Yang, thank you very much for your invitation, but I can't go."

Professor Yang's heart trembled, and he was about to speak anxiously, but thinking that it would be impolite to do so, he paused for a few seconds, calmed down, and asked in a very calm tone: "Why? It's because your Gaussian circle didn't If the research is successful, you can’t study it in the laser laboratory, you don’t want to suspend the research on Gaussian circles, do you?”

"It doesn't really matter. You can continue to study when you are free from experiments."

"I know that this will slow down your research progress, but laser weapon research is very important to our country."

"I think you are a person who sees the big picture, and I hope you can understand."

Ye Fei said: "I can understand, but what you said is only one of the reasons, but for me, there is another more important reason."

Professor Yang was puzzled, the more important reason?What more important reason?
Is this reason more important than the overall situation?
Ye Fei said: "You should know that I just became a teacher this year."

Professor Yang nodded. He had investigated Ye Fei's basic information before coming here, so he knew that Ye Fei had just become a teacher not long ago.

"I've only been teaching for a month, and I haven't finished teaching. Is it appropriate for you to let me leave my students at this time?"

Professor Yang's expression froze. Indeed, the book is not finished yet, so it is really inappropriate for Ye Fei to leave his students.

"Also, laser weapons should not be as necessary to our country as atomic bombs were decades ago!"

"If it is something that the country needs very much, even if I am sorry for my students, I will follow you to study laser weapons without saying anything."

"Isn't it okay for someone else to substitute for the class?" Professor Yang said with some reluctance.

"No!" Ye Fei shook his head: "The course I take is a bit special. It is a self-built course. All the content of the course is prepared by myself, and other teachers cannot substitute for it."

"I have to stop the class when I leave."

"It's fine if you stop for a few weeks, but it's not okay to stop for a long time."

"I think I will study laser weapons, not just for a few weeks, but at least a few months, or even a year."

"You really can't study laser weapons?"

"Really not!" Ye Fei said.

"All right!"

Professor Yang felt a little bitter in his heart. Although Ye Fei's reason was not a reason for him not to study laser weapons in his own opinion, Ye Fei had his own insistence.

Maybe it's not the reason in my opinion, but in Ye Fei's view, this is the reason.

Professor Yang stood up, let out a long sigh, and said helplessly: "I can't force others to do what they want, if you think about it, you can contact me, let's add a WeChat!"

As he spoke, Professor Yang took out his mobile phone from his trousers pocket.

"Okay!" Ye Fei also stood up, took out his mobile phone from his trousers pocket, and then the two added WeChat to each other.

"Goodbye!" Ye Fei shook hands with Professor Yang, who turned to leave.

Academician Liu patted Ye Fei on the shoulder and said with a smile, "Don't think too much, your idea is right."

After speaking, he shook hands with Ye Fei and left.

Ye Fei watched the two leave, shook his head in his heart, and then turned to leave.

"Professor Yang." Academician Liu caught up with Professor Yang and said, "Would you like to attend the dinner tonight?"

"No." Professor Yang shook his head, and said anxiously, "I'm here this time for Ye Fei. Ye Fei won't participate in the research of laser weapons, and I'm not in the mood to go to the dinner party. I'll go to the next place now and continue to look for opportunities to carry out research on laser weapons." A person who studies laser weapons."

"It's a pity..." Professor Yang sighed, and said with deep regret: "Ye Fei is the youngest among my favorites. He doesn't participate. I don't know if the research on laser weapons will be successful."

"Who else are you optimistic about?" Academician Liu asked doubtfully.

"Professor Ding Zhenyang from Shuimu University, Professor Xue Lifei from Fudan University, and Professor Deng Guangjian from Chang'an Jiaotong University."

"Professor Ding Zhenyang developed a narrow-band mid-infrared laser technology ten years ago."

"Professor Xue Lifei developed the white light laser technology of single nano-semiconductor ten years ago."

"Professor Deng Guangjian developed the space communication technology of sunlight-pumped laser technology five years ago."

Academician Liu asked suspiciously: "These three people are better than Ye Fei in laser technology. Why do you think Ye Fei is more optimistic?"

Professor Yang glanced at Academician Liu and shook his head inwardly.

But he could also understand that Academician Liu didn't study lasers, so he didn't know the truth about it.

Professor Yang said: "These three people are all applied technology, but in fact they all study Gaussian functions."

"Using the Gaussian function as a theory to create technology."

Academician Liu nodded, that's why.

For any technology, there is theory first, and then there is technology.

Theory is the foundation. If there is no theory, technology will not appear.

Generally, the theory is strong, and the technology is not too bad.

Academician Liu said: "So, because of this, do you like Ye Fei?"

"Yes!" Professor Yang nodded: "Ye Fei's theoretical research is not inferior to these three, the difference is only in technology."

"Besides, Ye Fei is still so young, and his thinking is more active than these three."

"So, I am more optimistic about Ye Fei, and I came to Ye Fei first."

"If Ye Fei agrees, the other three don't need to look for it."

Academician Liu nodded slightly: "Professor Yang, why don't you go to the dinner party, maybe there are talents you are satisfied with at the dinner party. After all, there are many well-known mathematicians at home and abroad at the dinner party. If you meet someone you are satisfied with, you don't have to run somewhere else."

"Besides, the dinner will start in a few hours, so don't be in a hurry for a few hours!"

After much hesitation, Professor Yang nodded in agreement and said, "Okay, then let's participate!"

At six o'clock in the evening, in a large private room of a five-star hotel near Zhonghu University.

It was decorated like a cafeteria, with a ten-meter-long table in the middle, covered with white cloth, filled with all kinds of delicious food and drinks.

Many people gathered together to chat with drinks or plates.

The place with the most gatherings was Ye Fei's circle. Ye Fei stood in front of a small whiteboard, writing and drawing on it, surrounded by many people.

Ye Feidao: "Most current sequence recommendation systems assume that predictions are needed..."

He's talking about the Gaussian distribution.

As mentioned earlier, the Gaussian distribution is a normal distribution, which has great influence in the fields of mathematics, physics and engineering.

With so many mathematicians present today, Ye Fei was very excited.

He could harvest another wave of inspiration, so before the dinner started, he thought of discussing his current research with everyone.

This will greatly promote his research progress.

When the explanation of Gaussian distribution was over, someone asked: "Ye Fei, I see that you have a deep research on Gaussian distribution. I am currently studying super-Gaussian beams. Do you know how to make super-Gaussian distribution describe the pump more accurately?" The distribution of light?"

The super-Gaussian distribution, as can be seen from the name, is an upgraded version of the Gaussian distribution.

The biggest difference is that for Gaussian distribution, the distribution state is normal kurtosis, and for super Gaussian distribution, the distribution state is peak kurtosis.

The state of the two is as if the Gaussian distribution is a calm lake, and the super-Gaussian distribution is a turbulent lake.

The pump light is to irradiate the working material of the laser with the light emitted by the external light source to realize the inversion of the particle number.

In layman's terms, we all played with infrared rays when we were young, and the infrared light irradiated in the dark is equivalent to pump light.

Ye Fei frowned in thought, and the people around were also discussing in low voices.

Holding a glass of red wine, Professor Yang walked aimlessly in the hall, listening to this crowd and listening to that crowd.

He's looking for talent.

"Hey..." He sighed in his heart: "Talents are hard to find. Those who are capable are not young, and the young are not capable. Compared with Ye Fei, they are far behind."

There is no harm if there is no comparison. After seeing Ye Fei's ability, he still leans towards Ye Fei.

Unknowingly, he wandered outside of Ye Fei's small circle and looked at Ye Fei who was frowning and thinking inside.

At this time, Ye Fei suddenly raised his head and said, "Everyone, look at what I came up with, I don't know if it's correct."

He picked up the black cloth hanging on the small whiteboard and erased what was written with black carbon pen on it.

Ye Feidao: "It is assumed here that the pump light is injected into the center of the end face of the laser medium along the axis of the laser medium (z=0)..."

Ye Fei wrote down the formula on the small whiteboard while talking.

Everyone nodded repeatedly, and the person who asked the question widened his eyes, as if suddenly enlightened.

He thought to himself: "So that's the case, why didn't I think of it, I'm so stupid."

At the same time, I was also amazed at Ye Fei's talent, really quick thinking.

And many others said: "It turns out that it is so simple, I should have thought of it!"

Everyone is sorry and surprised!
In fact, the solution is very simple. Many people seem to think of it, but they didn't think of it.

When I saw Ye Fei's solution, I seemed to be saying in my heart, so this is the case, I have thought of it a long time ago!
This is like an exam. The questions look simple, but you make mistakes as soon as you do it.

They are in this state at this time.

After seeing Ye Fei's solution, Professor Yang's eyes widened in surprise: "It turns out that he has such a deep understanding of Gaussian functions."

"It must be him, it must be Ye Fei."

There seemed to be a voice in his heart saying: "With Ye Fei joining, the laser experiment will definitely be successful."

He also studied the research of Gaussian functions by three other professors.

He thought that Ye Fei's Gaussian function research should be on par with these three professors.

But looking at it now, that's not the case.

Rather, Ye Fei is much stronger than them.

In fact, Ye Fei's understanding of the Gaussian function is also a month's study.

In addition to this dinner, many well-known mathematicians thought about Gaussian functions together.

This led Ye Fei to gain countless inspirations about Gaussian functions.

Professor Yang was troubled again: "But Ye Fei won't join!"

Torrey is a professor of mathematics at the University of Cambridge and an internationally renowned mathematician. He looked at what Ye Fei wrote on the small whiteboard, and said to his friend next to him: "Berry, believe it or not, Ye Fei will be in the near future. to reach the same heights as ours."

Berry also looked at the small whiteboard, nodded and said: "Yes, you can see that his problem-solving ideas are very novel, not at all like the problem-solving ideas that people in their 20s can give."

"It's as if you have been immersed in mathematics for 30 to [-] years before you can think of ideas."

Torre shook his head and said with emotion: "Xia Kingdom is really a magical country. It has experienced wars and declines, as well as prosperity and glory. For 5000 years, no matter what time it is, there are always talented people."

"Yeah!" Berry nodded, "Look, in the next 20 years, there will definitely be many Nobel Prize winners and Fields Medal winners in Xia Kingdom."

"Yes." Torre said: "Academics need precipitation, and Xia Guo's precipitation is enough."

Professor Yang saw that the dinner party was coming to an end soon, and he still had no idea how to get Ye Fei to join the laser experiment.

"Professor Yang, have you found a talent?" Academician Liu came over and asked with a smile.

Professor Yang shook his head and sighed, "Hey... I'm still optimistic about Ye Fei, no, I should say I'm more optimistic about Ye Fei than before the dinner."

Academician Liu was stunned, why is this even more optimistic?

He shook his head and laughed, "Although you are optimistic about Ye Fei, Ye Fei won't go!"

"That's why I'm very distressed!" Professor Yang said bitterly, "Can you get Ye Fei to study laser weapons?"

Academician Liu said: "It's not impossible to let Ye Fei only study laser weapons. I just thought of this method."

Professor Yang looked at Academician Liu expectantly for a moment, and urged, "Quickly tell me, what can I do?"

Academician Liu said: "Ye Fei just doesn't want to leave Zhonghu University, but you want Ye Fei to study laser weapons."

"Actually, the two do not conflict and can be achieved at the same time."

Professor Yang is puzzled, not knowing how to achieve the two at the same time.

Ye Fei will not leave Zhonghu University, but research on laser weapons must leave Zhonghu University.

The two are in conflict!

Academician Liu said: "Your school can move the laboratory to the sand dunes!"

Professor Yang's eyes widened for a moment, and then he said in surprise: "Why didn't I think of it."

"Oh..." Professor Yang patted his forehead and said with a smile, "I'm stuck in my mind, I've always wanted to tell Ye Fei to go to the laser laboratory."

"But Ye Fei won't go, Ye Fei won't go to the laser lab, I can let the laser lab go to Ye Fei!"

"If he doesn't go, we will come."

"Hahaha..." Professor Yang shook Academician Liu's hand excitedly, and said, "Thank you, Academician Liu."

Academician Liu smiled and said, "Hehe...no need."
