"Laser weapons research?" Ye Fei's eyebrows instantly clustered slightly, his eyes flickered, and his eyes showed a hint of hesitation.

His Gaussian circle had just begun to be studied, and he was only halfway through the first puzzle.

If he went to study laser weapons at this time, he would have to suspend the research of Gauss Circle, and he did not want to postpone it.

Moreover, not long after I became a teacher, I still have students to bring, and when I go to study laser weapons, I have to leave the students.

Leaving before the class is finished is irresponsible to the student.

"Any questions?" Professor Yang looked at Ye Fei hesitantly, his lips were pursed, he stared straight at Ye Fei, and asked with some apprehension: "If you have any problems, you can say anything, you can solve what can be solved, and if you can't solve it, you will find a way to solve it." ”

Ye Fei looked at Professor Yang worriedly, and felt a little reluctant in his heart, exhaled lightly, and asked, "Professor Yang, is it that if I go to research laser weapons, I will leave Zhonghu University and go to Kyoto University of Technology?" ”

"Yes!" Professor Yang nodded: "You have to go to the laser laboratory of Kyoto University of Technology, otherwise you will not be able to conduct research." ”

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

Professor Yang's heart froze, and he was about to speak anxiously, but thinking that it was rude to do so, he paused for a few seconds, eased his mood, and asked in a very calm tone, "Why?" It's because your Gaussian circle has not been successfully studied, and you can't study it when you go to the laser lab, and you don't want to put a hold on to the Gaussian circle, do you? ”

"It's okay, you can continue to research when you're experimenting."

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

"I think you're a big-picture person, and I hope you understand."

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

Professor Yang wondered in his heart, a more important reason? What could be more important?

Is this more important than the big picture?

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, so he knew that Ye Fei had just become a teacher.

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

Professor Yang's expression froze, indeed, the book has not been taught yet, and it is indeed inappropriate to let Ye Fei leave his students.

"Moreover, laser weapons should not be as needed in our country as the atomic bomb of a few decades ago!"

"If it's something that the country needs very much, even if I'm sorry for my students, I won't say a word, and I will follow you to research laser weapons."

"Isn't it okay for someone else to substitute for a teacher?" Professor Yang was still a little unwilling.

"No way!" Ye Fei shook his head: "The course I took was a little special, it was a self-built course, and all the course content was prepared by me, and other teachers couldn't substitute for it." ”

"If I leave, I have to stop the class."

"It's okay if you stop for a few weeks, but you can't stop classes for a long time."

"I think I'm going to work on laser weapons, not just for a few weeks, at least a few months, or even a year."

"You really can't study laser weapons?"

"Not really!" Ye Feidao.

"Okay!"

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

Maybe it's not a reason in his own opinion, but in Ye Fei's opinion, it's a reason.

Professor Yang stood up, sighed, and said helplessly: "I can't make it difficult for others, if you want to do it, you can contact me, let's add a WeChat!" ”

As he spoke, Professor Yang took out his 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 added WeChat to each other.

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

"Professor Yang." Academician Liu caught up with Professor Yang and said, "Do you want to attend the dinner tonight?" ”

"Nope." Professor Yang shook his head and said a little anxiously: "I'm here for Ye Fei this time, Ye Fei doesn't participate in laser weapon research, and I'm not in the mood to attend the dinner, I'll go to the next place now and continue to look for people who can conduct laser weapon research." ”

"It's a pity......" Professor Yang sighed and said with deep regret: "Ye Fei is the youngest among my most optimistic people, he doesn't participate, I don't know if the laser weapon research can be successful." ”

"Who else do you like?" Academician Liu said suspiciously.

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

"Professor Ding Zhenyang developed the narrow-spectrum and wide-spectrum mid-infrared laser technology ten years ago."

"Professor Xue Lifei researched the white light laser technology of monomer nanosemiconductors ten years ago."

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

Academician Liu said suspiciously: "The abilities of these three people are stronger than Ye Fei in laser technology, why are you more optimistic about Ye Fei?" ”

Professor Yang glanced at Academician Liu and shook his head in his heart.

But he can also understand that Academician Liu is not a researcher of lasers, so he doesn't know the Tao here.

Professor Yang said: "All three of them are applied to technology, but they are actually studying Gaussian functions. ”

"Using the Gaussian function as a theory, we created the technology."

Academician Liu nodded, I see.

Any technology has a theory first, and then there is a technology.

Theory is the foundation, and if there are no theories, technology will not appear.

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

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

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

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

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

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

Academician Liu nodded slightly: "Professor Yang, why don't you attend the dinner, maybe there are talents you are satisfied with at the dinner, after all, there are many well-known mathematicians at home and abroad at the dinner, and you don't have to go to other places when you meet someone who is satisfied." ”

"Besides, the dinner party starts in a few hours, so you don't have to rush these hours!"

After hesitating, Professor Yang nodded in agreement, "Okay, then let's participate!" ”

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

It is decorated like a cafeteria, with a ten-metre-long table in the middle covered with a white cloth filled with delicious food and drink.

Many people gather together to chat with drinks or plates.

Among them, the place where the most gathered is Ye Fei's circle, Ye Fei is standing in front of a small whiteboard, writing and drawing on it, and there are many people around him.

Ye Feidao: "Most of the current sequence recommendation systems assume that they need to predict ......"

He's talking about Gaussian distributions.

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

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

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

This will greatly facilitate the progress of his research.

When the Gaussian distribution was explained, someone asked: "Ye Fei, I see that you have a deep study of Gaussian distribution, I have been studying ultra-Gaussian beams recently, do you know how to make ultra-Gaussian distribution more accurately describe the distribution of pump light?" ”

The ultra-Gaussian distribution, as the name suggests, is an upgraded version of the Gaussian distribution.

The biggest difference is that the Gaussian distribution, the distribution state is constant kurtosis, and the ultra-Gaussian distribution, the distribution state is spike.

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

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

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

Ye Fei frowned and pondered, and the people around him were also discussing in whispers.

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

He's looking for talent.

"Hey......" he sighed in his heart: "It's hard to find talents, the capable ones here are not young, the young ones are not capable, and they are far behind Ye Fei." ”

There is no harm if there is no comparison, after seeing Ye Fei's ability, he is still inclined to Ye Fei.

Unconsciously, he walked outside Ye Fei's small circle and looked at Ye Fei, who was frowning and contemplating 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 had been written with a black carbon pen on it.

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

Ye Fei said as he wrote down the formula on the small whiteboard.

Everyone nodded their heads again and again, and the person who asked the question widened his eyes and looked like he had suddenly realized.

He said in his heart: "So that's the case, why can't I think of it, it's really stupid." ”

At the same time, I was also surprised by Ye Fei's talent, which was really quick-witted.

And many others said in their hearts: "So that's it, it's so simple, I should have thought of it!" ”

Everyone regrets and is surprised!

In fact, the solution is very simple, and many people seem to think of it, but they don't think of it.

When I saw Ye Fei's solution, I seemed to be saying in my heart, so that's the case, I thought of it a long time ago!

It's like an exam, where the questions look simple, but when you do it, you're wrong.

That's what they're in at this point.

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

"It has to be him, it has to be Ye Fei."

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

He has also studied the Gaussian function of three other professors.

He thought that Ye Fei's Gaussian function research should be half a pound and two with these three professors.

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

Instead, Ye Feidu is much stronger than them.

In fact, Ye Fei's understanding of Gaussian functions is also a month's learning.

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

As a result, Ye Fei gained countless inspirations about Gaussian functions.

Professor Yang was distressed in his heart: "But Ye Fei won't join!" ”

Torre, a professor of mathematics at Cambridge University and an internationally renowned mathematician, 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 reach the same height as us in the near future." ”

Berry also looked at the small whiteboard and nodded: "Yes, you see that his solution ideas are very novel, not at all like the solution ideas that people in their twenties can give." ”

"It's like immersing yourself in mathematics for twenty or thirty years before you can think of it."

Torre shook his head and said with emotion: "Xia Country is really a magical country, it has experienced war and decline, but also prosperity and glory, up and down for five thousand years, no matter at any time, there are always many talents. ”

"Hmm!" Berry nodded: "Look, in the next twenty years, there will definitely be many Nobel Prize 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 was about to end, but he still didn't think of how to get Ye Fei to join the laser experiment.

"Professor Yang, have you found a talent?" Academician Liu walked 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 that I'm more optimistic about Ye Fei than before attending the dinner. ”

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

He shook his head and smiled: "Although you are optimistic about Ye Fei, Ye Fei will not go!" ”

"That's why I'm distressed!" Professor Yang said with a bitter face: "Do you have any way to let Ye Fei study laser weapons?" ”

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

Professor Yang instantly 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 research laser weapons." ”

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

Professor Yang was puzzled, not knowing how to achieve both at the same time.

Ye Fei does not leave Zhonghu University, and the research of 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 instantly, and then he said in surprise: "I couldn't have imagined it. ”

"Oops......" Professor Yang patted his head and said with a smile: "I'm trapped by my thinking, and I always want to say, let Ye Fei go to the laser laboratory." ”

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

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

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

Academician Liu smiled: "Hehe...... No. ”
