"Nanofunctional materials and processing technologies are mainly through the composite of different semiconductor materials and the construction of micro-or nano-structures, the establishment of material microstructures, photoelectric conversion, photothermal conversion, etc."

August 25, 2018, Jingzhou City, Jingzhou University, School of Materials Engineering, Open Class.

Xu Yun listened to the course on nanomaterials from the academician of materials on the podium, but his eyes fell on the panel that was called.

"The progress of the task is almost halfway through, and I finally live up to the professional classes on time in the past few days."

Seeing that the cumulative time of the task had reached more than forty hours, he thought back to what he had done in the past ten days, and couldn't help but sigh in his heart.

In order to complete the task as quickly as possible and gain brain overclocking time, he is basically the same as a student in the School of Materials Engineering.

Even harder than they are.

In addition to taking professional courses every day, there has not been a single relevant open class.

On average, I attended at least five hours of classes a day.

At this rate, he has up to ten days before he can meet the requirements of the mission and receive the reward.

However, his approach has caused a lot of psychological pressure on students from other majors.

Let everyone be more convinced that chemical materials belong to sinkholes.

After all, even Xu Shen, who has a very high learning talent, needs to work so hard in the field of materials chemistry, and his diligence is far greater than when he was in other colleges before.

The difficulty can be imagined.

Hearing this rumor, Xu Yun couldn't cry or laugh in his heart, thinking that he had a negative impact on going to class on time.

But even so, until the task is completed, the lesson must be continued.

Of course, in a few days, he has gained a lot, not only has a clear understanding of the relevant knowledge of material chemistry, but also has a certain direction of the coating material required by the module robot.

In addition, he was not idle for advanced tasks, and he entered the sub-chemistry laboratory with Liu Jingying's consent in the middle.

It's just that although an experiment was successfully carried out, the results can only be described as miserable.

In addition to being a waste of materials, carelessness can also lead to great danger and even life safety.

Chemistry is not as safe as photoelectric safety, and if the process goes wrong, it is possible to cause an explosion.

For this reason, he finally decided to wait for the research of the coating material to be clear, and then conduct experiments to try to make this material.

"That's all for today's lesson, you can continue to sign up for the lecture next week."

Just as Xu Yun was thinking about this, the voice of the academician in the field of materials on the podium suddenly came to his ears.

Seeing that this open class was over, Xu Yun had no intention of continuing to stay in the classroom to delay time, and immediately got up and prepared to leave.

As the first day of the new year every year, Gyeongju University is undoubtedly very lively and cheerful at this time.

Xu Yun is already a doctoral student, and he definitely doesn't need him to welcome the new students, but he has to pick up his cousin.

Speaking of which, he was pleasantly surprised that Han Xiaoya was able to be sent to the Department of Mathematics of Beijing University and did not take the college entrance examination, after all, in some respects, this starting point is much stronger than he was at the beginning.

Originally, Han Xiaoya's parents planned to send their daughter to school today, but Han Xiaoya had to choose to take a car to Jingzhou City by herself.

In this case, his cousin must pick up people and arrange everything properly.

This is also something that his mother specially explained.

When Chen Shihe didn't go to Jingzhou, he also met Han Xiaoya a few times, and when he heard that the other party was going to study at Beijing University, he took the initiative to go to the station with Xu Yun to pick up people.

In this regard, Xu Yun naturally did not refuse.

Just as he was packing up his things and getting up to leave, he saw the academician standing in front of him.

A kind expression appeared on his face.

"Well, can I understand what I'm teaching?"

In the face of the academician's concern, although Xu Yun didn't react much in his heart, he immediately replied.

"I can understand it all."

Since the news that he was going to study materials chemistry spread in the college, professors and even academicians in related fields have been particularly concerned.

From time to time, I have to care about his learning, as if I am afraid that he will choose to give up halfway.

Fortunately, so far, this idea has not arisen.

"That's good."

"Your talent is indeed very strong, and it is not difficult for you to believe in the knowledge of chemical materials."

"You are welcome to come to my office at any time to discuss."

After listening to Xu Yun's answer, the academician dropped this sentence with a smile on his face before turning around and leaving.

When the other students next to him saw this scene, they sighed one after another and confided in their friends.

"You have seen it, even Xu Shen has to spend a lot of time studying materials chemistry to be diligent, and even the professors and academicians of the academy have to pay attention to it at any time, for fear that Xu Shen will not understand something."

"Ordinary people want to learn well, but I'm afraid it's ten times more difficult."

"The majors I choose now are all from the water in my head at the beginning, and they really deserve to be a sinkhole-level major."

"Regret it!"

In the face of his friend's complaints and accusations, the other party was suspicious, and he was even more curious that Xu Yun would choose to study material chemistry.

"It shouldn't be as outrageous as you said, but didn't Xu Shen come back from the imperial capital and say that he wanted to write a paper and not accept an interview, why did he suddenly come to our college to study materials and chemistry?"

"I don't know, maybe I like materials chemistry." The classmate shook his head and muttered.

It may be that it is really strange, and Xu Yun is usually more approachable and good at communicating, so in the end the other party chose to speed up the pace and catch up.

After being side by side with Xu Yun again, he took the initiative to ask.

"Hello senior."

"Can you ask the seniors because they like materials chemistry that they put aside their papers to study?"

Xu Yun replied to the academician in the field of materials, and was about to meet Chen Shihe and then drove to the station, when he suddenly saw a polite junior next to him and asked him a question.

"I'm really interested in materials chemistry, and as for the paper you said, it should be the Goldbach conjecture proof, and if nothing else, you should be able to retrieve this paper by now."

After speaking, without waiting for the other party to respond, he continued to take steps and left quickly.

After hearing the answer, the junior was stunned, his face full of shock.

"The paper has already been published?"

"So fast."

In any case, he could not have imagined that the writing and publication of papers could be so fast.

I recall the experience of publishing a paper for the first time and waiting for half a year to be sent back for revision.

I suddenly wanted to cry.

He shouldn't have asked that question in the first place.

In the eyes of ordinary people, this may be something that cannot be accomplished in a short period of time, but for the study of God, it will only seem easy.

However, he figured it out a little too late.

Looking at Xu Yun's figure that quickly disappeared from view, he suddenly thought of something and hurried in the direction of the dormitory.

For this kind of world-class paper, even if you don't have much research on mathematics, you have to take a look.

Xu Yun was not surprised that Goldbach's conjecture could be published so quickly, but it would be even more strange if it was delayed for too long.

So after receiving the email from Hofer, he took a casual look at it and put it there.

According to Hofer's instructions, after receiving the paper, the Annals of Mathematics immediately organized experts in the field of number theory to review and demonstrate, and published it in the journal as soon as possible under the condition of ensuring rigor.

In addition, because of the additional description of topological group theory in this paper, it is conceivable that it will be cited a lot in the future.

After all, the emergence of topological group theory has greatly stimulated the study of number theory by mathematicians and people around the world.

……

Compared with the calm on the campus of Beijing University, the mathematics community is in a carnival at this moment because of the publication of Xu Yun's paper.

Many mathematicians gave very high marks after reading the paper.

It may also be that some of the steps in the paper have been written at the mathematicians' conference, and the explanation of the topological group theory theory in it makes the questioning of the proof process very quiet.

Much better than when Hodge's conjecture was proved.

This is equivalent to the recognition of his proof process by the mathematical community, and at the same time, it represents the complete solution of the famous Goldbach conjecture of number theory.

At the same time, in the study room of a community, Zhang Yitang, who has returned to China, is seriously studying the latest issue of the mathematics yearbook he just got his hands on, trying to find his inspiration from Xu Yun's paper.

Since a brief exchange with Xu Yun, he always feels that the topological group theory proposed by Xu Yun is also the key to his proof of twin primes.

Now that topological group theory has been successfully perfected and applied to the conjecture of Goldbach's conjecture, he is even more hopeful that perhaps the long-term study of twin primes will finally come to fruition. Because of this incident, he even pushed off the assembly of mathematicians, and spent most of his time in his room and studied it carefully.

I don't know how long it took, but he slowly put down the journal and reached out to rub his eyes and temples.

Although he looked a little tired, his eyes showed a fine light, and the whole person seemed to be extremely excited.

"This direction is really right, as long as I continue to study along the lines of topological group theory, I will definitely be able to prove the twin primes thoroughly."

"It's really terrifying and admirable to be able to create such a subtle and novel theory."

While muttering in a deep voice, he immediately pulled out the scratch paper on the desktop in the next second, picked up the pen and continued to calculate.

The same situation is happening among other mathematicians, and it is conceivable that it will not be long before a large number of number theory problems will be solved, which will bring the development of mathematics into the best era.

In addition, it is worth mentioning that after the paper was officially published, many mathematics research institutes of well-known universities in the world publicly invited Xu Yun, hoping to conduct academic exchanges or even join them.

However, the Institute for Advanced Study in Princeton was very low-key this time, and it was obvious that they were very clear about Xu Yun's choice through the last exchange.

It's a pity that Xu Yun, who was driving to the station with Chen Shihe at the moment, didn't have time to pay attention to online information and check emails, but even if he saw it, he would definitely not choose to agree.

Not to mention that he just came back from overseas after attending the conference, the most important thing for him at the moment is to complete the task and get the reward.

Strive to make an automated intelligent module robot as soon as possible, where will waste time running around.
