Chen Shihe has obviously dressed up more carefully than usual today, wearing a square-necked black and white stitched fake two-piece long dress, and the French style looks more temperamental and radiant.

Coupled with the light makeup and lipstick on her face, you can see that she attaches great importance to today's family gathering.

At this moment, I felt the power from the palm of my hand, and I also showed my attitude generously.

"I have no opinion."

"It's okay to be engaged today, and when you two graduate, you can pick a date to hold a wedding." Zhang Wenyan saw that her favorite son-in-law finally got it, and she was so excited that she couldn't wait for the two to get married now.

However, completely piercing this window paper in front of the parents of both sides made the atmosphere of the private room better.

It's just that Xu Yun has encountered a problem at the moment.

Although today's situation surprised him a little, I have to say that it is a good thing.

If the family is stable, there is no need to be emotionally distracted, and academic research can be better conducted.

What's more, he also knows in his heart that although his mother has never urged him emotionally, it doesn't mean that he doesn't want to see him get married.

Now it can be regarded as completely making up for the regret.

But since it's an engagement, but there is no ring or anything like that in his hand, he can't help but feel that something is missing.

The main thing is that he didn't know about it in advance, and he didn't have time to go out to buy gifts when he was so energetic in mathematics abroad.

And just as he was thinking about it, something suddenly came to mind when he quickly took out a box from his bag, handed it to Chen Shihe, and slowly opened it, smiling at the corner of his mouth.

"This one for you as our engagement ring."

"Is this the Fields Medal?" Chen Shihe subconsciously blurted out when he saw the golden medals in the box.

Although she is not a math major, she still knows a lot about the Fields Medal.

It is possible to have a gold medallion representing the highest honor in the field of mathematics as an engagement gift.

I'm afraid there's nothing more romantic than that.

Its value is also far from comparable to that of a diamond ring.

But in the end, Chen Shihe shook his head and did not choose to take it.

"This medal is an honor you have obtained, and even if you want to give it, you should keep it for your aunt."

"I can't ask for it."

After speaking, he didn't forget to look at Wang Chunfang next to him.

"Listen to me, take it quickly, why are you so careful as a family." Wang Chunfang took the medal directly from her son's hand, and couldn't help but stuff it into Chen Shihe's hand.

In this regard, Xu Yun raised his hand and patted Chen Shihe's shoulder, and explained with a smile.

"The value of the medal is given by the mathematician, not to mention the things that the mother-in-law gives and the daughter-in-law can't refuse."

"Then I'll keep it for you first."

After hearing these words, Chen Shihe no longer insisted on it, nodded in response, and solemnly put the medal into his handbag.

……

……

After eating, he returned to the Emgrand Garden community, and Xu Yun sat at the computer desk in the study and skillfully opened the document.

Today, he has told Meng Songyan about the establishment of the foundation to set up the Xu Yun Mathematics Prize, and asked him to be responsible for completing this matter as soon as possible, so as not to affect the selection of the first Xu Yun Mathematics Prize next year.

With Meng Songyan's strength and the support of the Mathematics Society, there is no need to worry about encountering any resistance.

And maybe because he was in a happier mood today, and because it was still early, he planned to start writing his thesis.

In addition, it is worth mentioning that Yuan Chengming mentioned to him about the situation of Professor Ohno Xiong of Tojing University, but for this kind of person, it is not enough for him to invest too much time to care, at most it is a small episode in life, and he will not continue to ask if he knows.

Anyway, the other party's fate is all self-inflicted.

The process of proving Goldbach's conjecture, which he wrote in the report of the International Congress of Mathematicians, is a condensed version.

It's equivalent to writing only the core steps.

Since you want to write a paper, you must be very perfect, which also means that the amount of work will be relatively large.

Fortunately, the whole process was in his head, so he wouldn't waste too much time.

Put your hands on the keyboard and quickly type out the title of your paper.

"The process of proving Goldbach's conjecture based on a new way topological group theory."

It wasn't until almost twelve o'clock in the evening that Xu Yun stopped moving his fingers and wrists.

Looking at the all-English version of the paper on the screen, he muttered a few sentences to himself.

"At this rate, it should be completed in a few days, and then the study of materials and chemistry will begin in earnest."

The deep sleep time I had drawn earlier had long since been used up, and I couldn't stay up too long at night in order to ensure my mental state the next day, so I turned off the computer and went to bed.

——

"I've finally looked forward to you coming back, wait for me to come to the stage to participate in the solid-state lidar project report meeting."

August 6, 2018, Royal Capital University, LiDAR Joint Laboratory.

Pan Wenjun looked at Xu Yun, who Tang Kang had just picked up from the station, and even said what he wanted to do today.

Xu Yun originally planned to finish the paper in the next few days, so that the editor-in-chief of other journals would not have to contact him, but he received a call from Pan Wenjun before the paper was completed.

According to the content on the phone, the final report of the solid-state lidar project has been approved.

This means that the project has been successfully concluded.

Solid-state lidar technology has always been in a backward position in China, and it is an important technology that has been stuck.

Now that there is finally a major breakthrough, we must announce this good news to the outside world to show our strength.

That brings us to today's meeting.

The main content is to report the actual effect data of this domestic solid-state lidar.

At first, Xu Yun didn't plan to come, thinking that Academician Pan and the two professors would be there.

The result was unanimously vetoed.

According to everyone's intentions, he, as the designer of this solid-state lidar, will definitely attend the meeting.

Faced with this situation, he had to take the nearest high-speed train to rush over.

Following Pan Wenjun into the venue, he immediately felt that the eyes of those reporters were all gathered.

For reporters, they only knew that this was a project of the LiDAR Joint Laboratory of Imperial Capital University, and they didn't know that it was related to Xu Yun before, but now when they saw Xu Yun suddenly appear here, they suddenly felt that there was major news in it out of the sensitivity of news people.

As a key project, LiDAR technology was previously publicized when the project was established.

It was surprising that it could be completed in such a short time, but it might not be the same if Xu Yun joined.

In the face of this situation, although Xu Yun expected it when he came, after meeting reporters and other domestic scholars and experts in this field, his expression was somewhat unnatural.

After winning the Fields Medal, he has already turned down a lot of interviews, just to be able to complete his thesis with peace of mind.

Unexpectedly, because of the lidar project I participated in before, I still couldn't avoid contact with reporters.

Especially after seeing Pan Wenjun arrange his seat in the middle, he had to hurriedly excuse himself.

"Academician Pan."

"It's not appropriate, or I won't be on stage."

"How can that work?"

"You have the most credit for being able to complete this project ahead of schedule, and of course you have to be present on this occasion." Pan Wenjun grabbed Xu Yun and replied in a deep voice, obviously not planning to let him step down.

Faced with this situation, Xu Yun was full of helplessness, so he had to follow Pan Wenjun's arrangement and sit beside him.

And although the report meeting has not officially begun, many reporters in the audience are already discussing.

"Why did Dr. Xu appear here, didn't Jingzhou University announce that it would not accept interviews in the near future?"

"This is indeed a project of Imperial Capital University, and it stands to reason that even if he is invited to attend the report meeting, he should not sit in that position."

"Could it be that Xu Yun also participated in this project?"

"It is really surprising that this project has not even taken a year from the announcement of the project to the completion, and it seems reasonable to say that the project is progressing so fast because of Xu Yun's participation."

"At present, there is no interview with Xu Yun on the whole network, and today is a good opportunity."

……

Soon with the official start of the report meeting, Pan Wenjun talked about the measured data and practical application effect of FT300 solid-state lidar, and made it clear that this technology has led the international level.

Of course, Pan Wenjun did not forget to highlight Xu Yun's contribution to this project.

"The reason why the domestic solid-state lidar project can be completed in a short period of time and lead the international level mainly depends on the design scheme provided by Dr. Xu Yun, a full member of the project team."

"Dr. Yun Xu has been involved in research in our joint laboratory before attending the International Congress of Mathematicians."

"I would like to thank Jingzhou University and Dr. Yun Xu for their help in our project."

As Pan Wenjun's voice fell, he entered the reporter's question session, and the scene suddenly became very lively.

The reporters in the audience rushed to ask questions.

"I'm Wang Ying, a reporter from the main station, how did Dr. Xu join the LiDAR project and provide the design plan?"

"Does Dr. Xu also have a lot of research in the field of lidar?"

"Can you tell us how you felt about winning the Fields Medal?"

When Xu Yun heard the reporter's question, he was in a posture of going off, so he had to move the microphone to organize the verbal answer.

"For the questions that journalists and friends are concerned about, I joined the LiDAR project because of the recommendation of Dean Tang of the Department of Mathematics of Imperial Capital University, and I was originally only responsible for mathematical problems."

"Because I was interested in the field of lidar, I learned about it on my own and conducted research."

"I am also very happy that my design can be adopted by the project team and successfully develop a domestic solid-state lidar."

"As for the feeling of winning the Fields Medal, I think this should be the greatest pursuit of mathematicians."

Although Xu Yun didn't say it in too much detail, the reporters in the audience immediately caught the keyword.

Self-learning relevant knowledge in the field of lidar, and setting up a plan adopted by the project team to lead the international level in one fell swoop, these things will cause the whole network to be shocked by any one of these things, but Xu Yun seems reasonable.

However, after the report meeting, related news also sprung up on the whole network like mushrooms after a rain.

Netizens were surprised to find that Xu Yun, who had just occupied the hot search list for a few days, slaughtered the list again before he calmed down for two days.

At the same time, the combination of domestic solid-state lidar and Xu Yun is also destined to attract the attention of the whole network and even the world.
