Xu Yun thought that it might be about joining the research group, and he didn't care about joining Qian Yudong and Zhou Qi to talk about them, so he hurriedly put down his chopsticks, reached out and picked up his mobile phone and pressed the answer button.

Hearing the voice coming from the microphone, I couldn't help but have a little excitement on my face.

Without any hesitation, he replied immediately and decisively.

"Okay, Professor Tang."

He quickly cleaned up the scraps of rice on the table, then turned to the others in the dormitory.

"Professor Tang asked me for something in the past."

After the words fell, he picked up the garbage and walked towards the outside of the dormitory, looking very anxious.

Since the last time he told Tang Yanshan about his desire to join the research group, there had been no news, which made him worry about the advanced task and think about whether he could take other methods. Unexpectedly, Tang Yanshan's call came so timely and brought him this good news.

According to Tang Yanshan's brief description on the phone, there is indeed a topic that suits him very well at the moment.

In this case, it is definitely necessary to pass as soon as possible and decide the matter first.

Qian Yudong looked at Xu Yun's back, and until he completely disappeared from sight, he turned around and continued to look at Zhao Yuefeng and Zhou Qi.

"Have you seen it, how can Xu Yun, a busy person, have time to participate in the school's sports meeting."

"So let's let me, the head of the house, bear it."

"Actually, there is one thing I haven't said, I used to run a lot in high school, and I will never disgrace our dorm room that day." Qian Yudong recalled his demeanor in high school, and did not forget to specially instruct Zhao Yuefeng and Zhou Qi: "And the two of you must be present for me that day, I will first overpower others in momentum." ”

Zhao Yuefeng and Zhou Qi didn't pierce Qian Yudong's Xiao Jiujiu, and when they heard this, they all nodded in agreement with a smile on the corner of their mouths.

It's true that they like the excitement of the Games, but they really don't want to participate in the event.

Whether Qian Yudong really loves sports, or wants to be close to the cheerleaders in other departments, at least he took this matter down.

When several people in the dormitory were discussing the details of the sports meeting, Xu Yun had already come to Tang Yanshan's office.

Seeing the door open, he walked in directly, and said hello to Tang Yanshan, who was sitting on a chair.

"Professor Tang."

"You're here just in time, I'll go to the courtyard to report later, I'll say hello over there."

Professor Tang saw that it was Xu Yun coming over, and immediately opened his mouth to explain.

It's just that this sudden word made Xu Yun a little confused, and it seemed that the way things unfolded was a little different from what he imagined.

Isn't it a research group of the Department of Mathematics?

What am I going to do in the courtyard?

muttered to himself in his heart, and hurriedly asked out loud in the next second.

"Professor Tang."

"Is there something wrong?"

"Wasn't it the research group in our department that let me in?"

"Why do you want to go to the Courtyard?"

Hearing this, Tang Yanshan reacted quickly, and immediately explained with an embarrassed smile on his face.

"I forgot to tell you, at present, there is no suitable topic for you in our department professor or doctor, it just so happens that Lao Yang of the Institute of Physics is studying carbon nanotube electron black body, and someone needs to geometrically model the vertical array of nanotubes, which is more suitable for you and will also be of great help to you to participate in the Higher Education Society Cup in the future."

"That's why I recommended you to Lao Yang."

"It just so happens that this work is not heavy, and it won't affect your ability to study other courses."

Xu Yun listened to Tang Yanshan's words, and then he realized that the other party had thought about so many things for himself.

Although I didn't get into the research group of the Department of Mathematics in the end, I went to the Faculty of Physics by chance, but I got the opportunity to complete the advanced task.

There's nothing to regret.

Thinking about this, he no longer hesitated, and immediately nodded in agreement with this arrangement.

"I understand Professor Tang, I'll go to the Institute of Physics later."

"Lao Yang and I have a good relationship, if there is anything I don't understand, I will go directly to him for advice." Tang Yanshan thought about it and specially instructed: "We are not embarrassed here. ”

"It's nothing else, then you can go over."

"Thank you, Professor Tang." Xu Yun thanked him again from the bottom of his heart, and then turned around and left.

……

Compared with the Department of History, the School of Physics is closer to the Department of Mathematics, Xu Yun went to the School of Physics before to listen to Xu Chongxing's open class, and it didn't take long to come over again.

He knew that the old Yang in Tang Yanshankou was Yang Huaping, a professor at the Academy of Physics, who was in charge of the low-dimensional quantum key laboratory.

is almost the same age as Tang Yanshan.

According to the information, he came to an experimental building in the institute, and soon walked to the door of Yang Huaping's office.

Usually, because Tang Yanshan is already familiar with him, he naturally doesn't feel nervous and restrained, but now when he wants to report to Yang Huaping, the whole person's mood is completely different.

He took a deep breath as he stood in the doorway, then raised his hand and knocked on the door.

"Please come in."

Yang Huaping's voice came from the room, and Xu Yun pushed the door in, and his sight was suddenly occupied by a middle-aged man wearing a navy blue lapel jacket with a ruddy face and a spirit in his eyes.

Raising his eyes and looking carefully, it can be clearly seen that Yang Huaping is younger than Tang Yanshan in appearance.

Coupled with Junlang's eyebrows and tall posture, it is conceivable that the other party should also be a handsome guy when he was young.

However, after looking at it, Xu Yun did not forget to take the initiative to introduce his identity.

"Hello Professor Yang."

"My name is Xu Yun, and Professor Tang asked me to come to you."

Yang Huaping saw that Xu Yun was still thinking about his identity, and after hearing this name and Tang Yanshan's relationship, he immediately reacted, and his face was full of enthusiasm.

"You're that Xu Yun, sit down first."

Facing Yang Huaping's greeting, Xu Yun no longer twisted at this time, and immediately sat down in front of the other party.

As soon as his butt was next to the chair, Yang Huaping's voice sounded in his ears again.

"I always heard from your Dean Qin that the Department of Mathematics of Beijing University recruited a good seedling this year, and today I finally saw it with my own eyes."

Originally, Xu Yun maintained a modest face, but when he heard this sentence again, he suddenly showed a little embarrassment.

I really didn't expect to hear Dean Qin's name everywhere I went.

It's really a top chatterbox.

I can't help but talk to anyone else about anything.

It's just that in this way, if you don't win the trophy by then, it's not just a shame in the department.

I'm afraid the whole school will talk about it.

didn't want Yang Huaping to talk too much about this matter, so Xu Yun simply took the initiative to divert the topic.

"Professor Yang, I have now registered, when can I officially start participating in the research of the project?"

"Don't rush this first, I'll have someone take you to the lab later, and understand our project and what you have to do clearly." Yang Huaping was very satisfied with Xu Yun's fighting spirit, and the smile on his face never disappeared when he took over the conversation and explained.

As soon as he finished speaking, he seemed to think of something, and spoke again.

"Old Tang has told me about your situation, and this time it should be regarded as familiarizing yourself with the process of subject research."

"Gain some practical experience in mathematical modeling."

"As for the research project, you don't have to worry, you just need to complete the tasks assigned to you on time, anyway, the difficulty is not very high, and your level is enough to be competent."

"I'll work hard, Professor Yang."

Xu Yun listened to all of Yang Huaping's words, although he answered sincerely on the surface, he was actually a little bitter in his heart.

According to the requirements of the advanced task, the magnitude of the improvement of new abilities is directly proportional to the contribution made to the research of the topic.

In other words, the greater his contribution to this research, the greater the improvement in ability at the end of the project.

Listening to the meaning of Professor Yang's words now, he should not be assigned too many tasks.

In this way, I am afraid that it may be difficult to substantially improve the new ability by waiting for the project to be completed.

I really became familiar with the process and accumulated experience.

But now I have finally waited for such an opportunity to participate in the research project.

You certainly can't just give up.

What's more, it was the opportunity for him to take the initiative to apply for Tang Yanshan, and if he quit halfway, he would definitely not be able to explain.

Thinking about these things clearly, he decided to stabilize first, and then see if there were other ways to improve his contribution.

In the following time, Yang Huaping did not keep Xu Yun, and called one of his graduate students to take Xu Yun to the laboratory.

……

The low-dimensional quantum key laboratory of the Institute of Physics is located in a humble building in the northwest corner, but there are hundreds of millions of equipment in it, which is incomparable to other colleges.

"The optical blackbody is an ideal optical absorber, with an absorption rate of nearly 100% for incident photons, and the most ideal is the carbon nanotube vertical array blackbody."

Outside the building where the laboratory is located, Jiang Yunxu, a graduate student of Yang Huaping, is introducing the content of his research topic to Xu Yun.

"We found that the vertical array of carbon nanotubes is not only an ideal optical absorber, but also may have an absorption coefficient of nearly 100% for the incident electrons."

"We are currently working on the ideal planar electron blackbody that would prove this idea."

"As long as the calculation formula of electron radiation is successfully derived and verified by electron spectroscopy, then the paper can be officially concluded and published."

The two talked along the way, and it didn't take long for them to enter the laboratory.

It was the first time for Xu Yun to see a laboratory of this level, and while listening to Jiang Yunxu's explanation, his eyes were also curiously looking at the surrounding environment.

The interior of the laboratory is essentially the same as that of the teaching building, except that the classrooms have been eliminated and turned into departments with various signs, and researchers in white coats can be seen coming and going from time to time.

At this time, when the two of them walked to the door of a department, they saw Jiang Yunxu stop and said with a smile: "We have arrived, this is where the members of our research group work." ”

Following Jiang Yunxu pushing the door and walking in, many special analytical instruments suddenly came into view.

Some of them resemble printers.

But in terms of value alone, it must be incomparable to any number of printers.

After getting acquainted with Jiang Yunxu, Xu Yun was no longer restrained, and immediately asked him about the most important thing to him.

"That Senior Brother Jiang, I don't know what my specific work is, you better tell me about it first."
