From university academician to chief academician

"Laser weapon research?" Ye Fei's eyebrows suddenly furrowed, his eyes flickered, and there was a hint of hesitation in his eyes.

He had just started studying the Gaussian circle and was only halfway through the first difficult problem.

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

Moreover, I had just become a teacher and had students to take care of. At this time, if I wanted to study laser weapons, I would have to leave the students.

Leaving before the class is over is irresponsible to the students.

"Is there any problem?" Professor Yang looked at Ye Fei's hesitation. He pursed his lips tightly and stared at Ye Fei. He asked with some anxiety: "If you have any problems, you can tell me and I will solve them for you. If we can’t solve it, I’ll find a way to solve it for you.”

Seeing Professor Yang's anxiety, Ye Fei felt a little regretful. He exhaled softly and asked, "Professor Yang, does it mean that if I go to study laser weapons, I have to leave Zhonghu University and go to Kyoto Institute 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 said regretfully: "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? Is it because your Gaussian circle is not there?" If the research is successful, you can no longer study it in the laser laboratory. You don’t want to postpone the research on the Gaussian circle, do you?”

"It actually doesn't matter. You can continue researching when you have free time while doing experiments."

"I know 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 Feidao: "I can understand, but what you said is only one of the reasons, but for me, there is a more important reason."

Professor Yang was confused, what's the more important reason? Is there any more important reason?

Is this reason more important than the overall situation?

Ye Feidao: "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.

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

Professor Yang's expression froze. Indeed, it was inappropriate for Ye Fei to leave his students before the book was finished.

"Besides, laser weapons should not be as needed in our country as the atomic bombs were decades ago!"

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

"Isn't it okay if someone else takes over the class?" Professor Yang still said unwillingly.

"No!" Ye Fei shook his head: "The courses I take are somewhat special. They are self-constructed courses. All course content is prepared by myself. Other teachers cannot teach on my behalf."

"I have to stop class when I leave."

"It's okay if it's a few weeks, but it's not okay if we stop school for a long time."

"I think it won't be just a few weeks if I study laser weapons, at least a few months, or even a year."

"You really can't study laser weapons?"

"It really can't be done!" Ye Feidao said.

"All right!"

Professor Yang felt a little bitter in his heart. Although Ye Fei's reasons did not seem to him to be his reason for not studying laser weapons, Ye Fei had his own persistence.

Maybe it wasn't a reason in his own eyes, but in Ye Fei's eyes, this was the reason.

Professor Yang stood up, sighed, and said helplessly: "I can't force others to do anything. If you think about it, you can contact me and let's add WeChat!"

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

"Okay!" Ye Fei also stood up and took out his mobile phone from his pants pocket, and then the two of them texted each other on WeChat.

"Goodbye!" Ye Fei shook hands with Professor Yang, and Professor Yang turned and left.

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

After saying that, he shook hands with Ye Fei and left.

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

"Professor Yang." Academician Liu caught up with Professor Yang and said, "Are you attending the dinner tonight?"

"No." Professor Yang shook his head and said anxiously: "I came here this time just for Ye Fei. Ye Fei is not participating in laser weapon research, and I am not in the mood to attend the dinner. I will go to the next place now and continue to look for candidates. People who work on laser weapons.”

"What a pity..." Professor Yang sighed and said with deep regret: "Ye Fei is the youngest among the people I am most optimistic about. If he doesn't participate, I don't know if the laser weapon research can 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 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 doubtfully: "These three people are better than Ye Fei in laser technology. Why do you think more highly of Ye Fei?"

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 behind it.

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

"Using Gaussian function as theory to create technology."

Academician Liu nodded, that’s it.

Any technology must first have theory and then technology.

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

Generally, they are strong in theory and not too bad in technique.

Academician Liu said: "So, because of this, you are optimistic about Ye Fei?"

"Yes!" Professor Yang nodded: "Ye Fei's theoretical research is as good as these three, the only difference is his technology."

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

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

"If Ye Fei agrees, there is no need for the other three to find him."

Academician Liu nodded slightly: "Professor Yang, why don't you go to the dinner party? Maybe there will be 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 there. Somewhere else.”

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

After much hesitation, Professor Yang nodded and agreed: "Okay, let's participate!"

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

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

Many people gathered together to chat, holding drinks or plates.

The most crowded place 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 of the current sequence recommendation systems assume that prediction is needed..."

He is discussing Gaussian distribution with everyone.

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

Ye Fei was very excited to have so many mathematicians present today.

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 done in-depth research on Gaussian distribution. I have been studying super-Gaussian beams recently. Do you know how to make super-Gaussian distribution describe the pump more accurately?" The distribution of light?”

Super Gaussian distribution, as you can tell from the name, is an upgraded version of Gaussian distribution.

The biggest difference is that for Gaussian distribution, the distribution state is constant kurtosis, and for super-Gaussian distribution, the distribution state is kurtosis.

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

Pump light uses light emitted by an external light source to irradiate the laser working material to achieve particle number inversion.

To put it in layman's terms, we all played with infrared rays when we were children. The infrared light irradiated in the dark is equivalent to pump light.

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

Professor Yang held a glass of red wine and walked aimlessly in the hall, listening to this group of people and then listening to that group of people.

He's looking for talent.

"Hey..." He sighed in his heart: "Talents are hard to find. Those who are capable here are not young, and those who are young are incompetent. They are far behind Ye Fei."

There is no harm without comparison. After seeing Ye Fei's ability, he still preferred Ye Fei.

Unknowingly, he wandered outside 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 is correct."

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

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

Ye Fei wrote the formula on the small whiteboard as he spoke.

Everyone nodded as they watched, and the person who asked the question widened his eyes, as if he suddenly understood.

He thought to himself: "So that's how it is. Why didn't I think of it? I'm so stupid."

At the same time, I was also surprised by Ye Fei's talent and his quick thinking.

And many others thought: "So that's it, it's so simple, I should have thought of it!"

Everyone was sorry and surprised!

In fact, the solution is very simple. Many people seem to have thought of it, but never thought of it.

When I saw Ye Fei's solution, I seemed to be saying, "So that's it, I've thought of it a long time ago!"

This is like an exam. The questions may look simple, but you will make mistakes as soon as you do them.

This is their current state.

After Professor Yang saw Ye Fei's solution, his eyes widened in surprise: "It turns out he has such a deep understanding of the Gaussian function."

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

There seemed to be a voice in his heart saying: "With Ye Fei's participation, the laser experiment will definitely succeed."

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

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

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

Instead, Ye Fei was much stronger than them.

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

In addition to this dinner, many well-known mathematicians were thinking about the Gaussian function together.

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

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

Torre 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 a mathematician in the near future." Reach our same heights.”

Berry also looked at the small whiteboard, nodded and said, "Yes, look at his problem-solving ideas. They are very novel. They are completely unlike the problem-solving ideas that people in their twenties can give."

"It's like being immersed in mathematics for twenty or thirty years before you can come up with an idea."

Torre shook his head and said with emotion: "The Xia Kingdom is really a magical country. It has experienced wars and decline, as well as prosperity and glory. For five thousand years, there are always talents emerging in large numbers at any time."

"Yeah!" Berry nodded: "Let's see, in the next twenty years, there will be many Nobel Prize and Fields Medal winners in Xia Country."

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

Professor Yang saw that the dinner was coming to an end soon, but he still didn't think of how to get Ye Fei to join the laser experiment.

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

Professor Yang shook his head and sighed: "Hey... I am still optimistic about Ye Fei. No, I should say I am more optimistic about Ye Fei than before attending the dinner."

Academician Liu was stunned, how could he be more optimistic about this?

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

"So I'm very troubled!" Professor Yang said with a bitter look on his face: "Is there any way you can make Ye Fei study laser weapons?"

Academician Liu said: "If it is not impossible to just let Ye Fei research laser weapons, I just thought of this method."

Professor Yang looked at Academician Liu expectantly and urged: "Tell me quickly, what can you do?"

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

"In fact, the two are not in conflict and can be achieved at the same time."

Professor Yang was confused and didn’t know how to achieve both at the same time.

Ye Fei did not want to leave Zhonghu University, but he must leave Zhonghu University to study laser weapons.

These 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: "I never thought of it."

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

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

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

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

Academician Liu smiled and said: "Haha... no need."
