Chapter 77 Another paper to write

After Xu Chongxing's personal confirmation, no one in the class doubted Xu Yuan's decision to study two majors at the same time. It was only at this time that they realized that it was not that the task was too difficult, but that their strength and talent were too poor.

While I envy Xu Yuan, I also admire his courage to challenge.

If they had such good grades in mathematics, they would definitely not make it more difficult for themselves.

Then go and learn a new professional course.

So after the class, many people took the initiative to run to Xu Yuan's seat to ask for his contact information.

He said that he would ask Xu Yuan for advice on engineering mechanics in the future.

In response to this, Xu Yuan was also enthusiastic and kind, and took the initiative to tell everyone his Penguin ID.

When most of the students in the classroom had left, he prepared to make a phone call to Li Zhenya and others to meet up in the cafeteria for dinner.

Xu Yuan had just taken out his cell phone and hadn't found Li Zhenya's number when he suddenly saw Xu Chongxing walking towards him.

He paused, glanced over and shouted.

"Professor Xu."

"Don't be nervous, I just want to have a brief chat with you." Xu Chongxing said as he stopped half a meter away from Xu Yuan.

Perhaps because he knew that she didn't look very good last time, he deliberately put on a smile in an attempt to build some goodwill.

Seeing the small changes in Xu Chongxing's facial expression, Xu Yuan couldn't help but want to laugh.

When I was a graduate student in my previous life, I had never seen my supervisor act like this.

After controlling his emotions a little, he took over the conversation and said, "Professor Xu, please feel free to say anything you want to say."

"Students, listen."

Upon hearing this, Xu Chongxing did not keep the topic in suspense and started chatting the next second.

"To be honest, I was surprised by your performance in this exam. You were able to get full marks on the test paper I gave you, which shows that you have a solid grasp of the knowledge of engineering mechanics."

"I misunderstood you before."

"Professor Xu, you are too kind. I can only understand the knowledge of engineering mechanics based on my mathematical foundation." Xu Yuan replied to Xu Chongxing very humbly.

"The study of engineering mechanics is indeed inseparable from mathematics." Xu Chongxing nodded in agreement with Xu Yuan's words.

Then, as if he had made a decision, he immediately said, "In that case, you can arrange your own courses from now on."

"I believe you can balance these two majors."

Previously, he only wanted Xu Yuan to focus on engineering mechanics, but now it is obviously not feasible.

After all, with Xu Yuan's mathematical talent, it is impossible for him to give up research.

If this is true, I'm afraid that the group of science professors from the School of Mathematical Sciences will come to him collectively to ask for an explanation.

A fluid mechanics research institute alone may not be able to sustain the economy.

Therefore, it is better for Xu Yuan to arrange his time by himself. At least there is no problem now.

Otherwise, Xu Yuan would not have been able to get full marks on his test paper.

"Thank you, Professor Xu."

Xu Yuan felt a little relieved when he heard that he no longer had to worry about classes.

This way he can make better use of his time in the future.

However, Xu Chongxing obviously had more to say, and he suddenly asked another question the next second.

"You are also very knowledgeable about fluid mechanics and aerodynamics?"

Hearing this, Xu Yuan immediately realized that this was probably because of the last aircraft design question on the test paper. There was no point in keeping it a secret and he admitted it directly.

"I have read the relevant information and documents in the school library. The shape and structure of the aircraft were also designed based on the paper published by Academician Song Wencong in the China Engineering Science."

At the end, Xu Yuan even took the initiative to mention his own design plan and the source of his inspiration.

As the chief designer of the J-10, Song Wencong boldly adopted the canard layout in the fighter's appearance design very early on.

And published a paper entitled Research on Aerodynamic Layout of a High-Lift Aircraft with Small Aspect Ratio.

Xu Yuan has studied this paper both in his past life and now. It was based on this paper that he innovated the aerodynamic layout of the canard, blending the canard with the winglets and lifting body.

Xu Chongxing did not delay any longer and finally told everyone what had been on his mind over the past two days.

"Actually, I didn't expect you to be able to answer this last question, but it turned out to be the biggest surprise for me."

"You know Xu Yuan?"

"Your innovation in the canard aerodynamic layout is likely to make up for the shortcomings of the canard."

"If the simulation data proves this inference is accurate, then it is very likely that the shape and structure layout of our country's latest generation of stealth fighter jets can be officially determined and the project can be approved."

Speaking of this, Xu Chongxing also became very excited.

It seems as if the image of the latest generation of stealth fighter jet successfully taking off for the first time, soaring into the blue sky and shocking the scoundrels has already emerged in my mind.

"So I hope you can write a detailed paper on the aerodynamic layout of the canard, wing slats and lifting body, and then participate in the selection meeting of the latest generation of stealth fighters."

After listening to all of Xu Chongxing's words, Xu Yuan was extremely surprised.

I didn't expect that a design problem I did casually might actually promote the project of the latest generation of stealth fighter jets.

You have to know that the latest fifth-generation stealth fighter project in the previous life was not approved until several years later. Although the development of the entire fighter includes many aspects, various parameter structures need to be discussed and decided many times, and it is impossible to do it with personal ability alone, but he still has the confidence to design the aerodynamic layout of the fighter.

He didn't have the chance to participate in it in his previous life, so how could he just watch it slip away from his hands now?

So without much hesitation, he agreed.

"I understand, Professor Xu. I will find time to complete the detailed layout plan later."

Hearing the answer he wanted, Xu Chongxing's face suddenly lit up, and he subconsciously blurted out:
"How long do you want?"

"I can't predict this for now." Xu Yuan said with a smile.

He could naturally understand Xu Chongxing's feelings. He wanted to see this innovative paper on the duck-style layout as soon as possible, but the amount of content in such a design paper was very astonishing.

It would definitely take him a long time to write it alone.

Besides, he also had things to do in mathematics and it was impossible for him to spend the whole day writing design plans.

Fortunately, he can easily enter the deep learning state, which can greatly improve his efficiency.

"I have to give a presentation at a number theory conference next week, but I will perfect this aerodynamic layout as soon as possible."

Xu Chongxing finally realized Xu Yuan's mathematical talent. He had just solved the problem of the intervals between Carmichael numbers, so it was indeed difficult for him to rest for a short period of time.

His thoughts stayed here, and his emotions quickly calmed down a lot.

"I was just too anxious about this matter. Anyway, if you have any questions, you can come to my office at any time."

Finally, Xu Chongxing left these words and did not delay Xu Yuan's meal any longer.

……

After Xu Yuan and Xu Chongxing separated, they hurried to the cafeteria entrance and reunited with Li Zhenya and others.

"Did the teacher keep the class late, Brother Yuan? You were really slow to finish the get out of class today?"

Wang Haitao looked at Xu Yuan, who was still a little out of breath when he rushed over, and asked curiously, because he had never met a teacher in college who would keep the class so long.

Logically speaking, it should only exist in junior high and high schools.

"No."

"Professor Xu from the Institute of Fluid Mechanics wanted to talk to me about something, so I came back a little late."

When asked, Xu Yuan didn't hide anything. He talked as he walked into the cafeteria with everyone.

"Tell me what good news is going on?" Li Zhenya became interested when he heard that.

As an undergraduate student of the School of Mathematical Sciences, he did not know who Professor Xu mentioned by Xu Yuan was, but based on his subjective judgment, he judged that there must be something going on that made the professor stay alone.

"It's not a good thing, after all, the workload this time is not small." Xu Yuan suddenly stopped and turned around and said, "It's just that writing a paper involving engineering mechanics will not be too smooth."

As soon as these words were spoken, the people around them suddenly widened their eyes and subconsciously couldn't help but exclaimed.

"Brother Yuan, are you going to write a paper again?"

"Do you want to publish your paper on engineering mechanics in two different journals? Which international journal are you going to publish it in this time?"

"I am completely convinced by Brother Yuan."

They all knew that Xu Yuan had just published a paper in the annual journal not long ago, but they didn't expect that the heat of this matter had not yet completely died down, and he was going to make a big splash in the field of engineering mechanics.

There is really no way out for ordinary students like them. As their roommate, it is really difficult.

Xu Yuan was quite helpless facing these funny guys in his dormitory. Fortunately, the noise in the cafeteria was quite loud and did not attract other people's attention, otherwise it would be a complete social disarray.

He rolled his eyes at them and said unhappily, "This paper will not be published in an overseas journal."

And after he finished speaking, he forced himself to change the subject.

"Let's think about what to eat for lunch today?"

Li Zhenya and others, who were originally in amazement, suddenly came to their senses and started a heated discussion when they heard about the meal.

"How about ramen? The one in the east window has a lot of beef."

"I'm having potato and beef brisket rice bowl today."

"Chicken soup and shredded pork noodles with a portion of stir-fried pork." Liu Yang finally took over the conversation and added with great enjoyment.

Just as they started to eat with relish, in the afternoon the Chinese Mathematical Society and Qinghua University and Yenching University jointly issued several announcements regarding a two-day academic conference on number theory to be held over the weekend.

We sincerely invite mathematics professors and number theory scholars from universities at home and abroad to participate in the exchange.

For domestic scholars, no matter who gives the report, they will attend just because of the reputation of the Mathematical Society and Yenching University.

On the contrary, overseas parties, relying on their authority in the international mathematics community, are often reluctant to come and communicate.

The situation would have been even more serious if Yenching University had not hosted the International Congress of Mathematicians last year.

All I can say is that China still has a long way to go in academic research in the field of mathematics.

However, as the founder of the Annals of Mathematics, Princeton University must have sent someone to show its support since it included Xu Yuan's paper. Another person is Professor Pomerance from Dartmouth College.
