"Nano functional materials and processing technology mainly establish material microstructure and photoelectric conversion, photothermal conversion, etc. through the compounding of different semiconductor materials and the construction of micron or nanostructures."
On August 25, 2018, Jingzhou City, Jingzhou University School of Materials Engineering opened an open class.
Xu Yun was listening to the materials academician's lecture on nanomaterials on the podium, but his eyes fell on the summoned panel.
"The task is almost halfway through, and I finally managed to live up to my expectations of attending lectures and attending professional classes on time these past few days."
Seeing that the cumulative time of the mission had reached more than forty hours, he recalled 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 to obtain brain overclocking time, he is basically no different from the students of the School of Materials Engineering.
Even harder than them.
In addition to taking professional courses every day, I have never missed a single relevant open class.
On average, I have at least five hours of classes every day.
At this rate, it would take up to ten more days for him to meet the mission requirements and receive the reward.
However, his approach caused a lot of psychological pressure on students in other majors.
Let everyone be more convinced that chemical materials belong to the sinkhole.
After all, even Xu Shen, who has extremely high learning talent, needs to work so hard in the field of materials chemistry, and his diligence is far more than when he was in other colleges.
The difficulty can be imagined.
Xu Yun couldn't laugh or cry when he heard this rumor, thinking that attending classes on time would actually have a negative impact.
But even so, the class must continue until the task is completed.
Of course, he gained a lot in a few days. Not only did he have a clear understanding of material chemistry, but he also had a certain idea of the direction of coating materials required for modular robots.
In addition, he was not idle in the advanced tasks, and got Liu Jingying's permission to enter the sub-chemistry laboratory.
It's just that although an experiment was successfully conducted, the results can only be described as horrific.
In addition to wasting materials, not paying attention may also cause great danger and even life safety.
Chemical things are no safer than photovoltaics. If the process goes wrong, it may cause an explosion.
For this reason, he finally decided to wait until the research on coating materials was clear before conducting experiments to try to make this material.
"That's it for today's course. You can continue to sign up next week to attend the lecture."
While Xu Yun was thinking about this, the voice of an academician in the field of materials on the podium suddenly reached his ears.
Seeing that the open class was over, Xu Yun had no intention of staying in the classroom to waste time, and immediately stood up to leave.
As the first day of school for new students every year, Jingzhou University is undoubtedly very lively and cheerful at this time.
Xu Yun is already a doctoral student and there is definitely no need for him to go to welcome new students, but he has to pick up his cousin.
Speaking of which, he was quite surprised that Han Xiaoya was recommended to the Mathematics Department of Peking University and did not take the college entrance examination. After all, in some ways, this start was much better than his original one.
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 the person and make all arrangements properly.
This was also something his mother specifically told him.
When Chen Shihe didn't go to Jingzhou, he met Han Xiaoya several times. When he heard that she was coming to Beijing University to study, he took the initiative to pick her up at the station with Xu Yun.
Xu Yun naturally did not refuse.
Just when he packed his things and was about to get up and leave, he saw the academician standing in front of him.
A kind expression appeared on his face.
"How's it going? Do you understand what I'm teaching?"
Faced with the academician's concern, Xu Yun responded immediately, although he didn't react much in his heart.
"I can understand them all."
Since the news that he wanted to study materials chemistry spread in the college, professors and even academicians in related fields have become particularly interested.
From time to time, I have to care about his study status, as if he is afraid that he will give up halfway.
Fortunately, this idea has not appeared so far.
"That's good."
"Your talent is indeed very strong. I believe that your knowledge of chemical materials will not be a problem for you."
"You are welcome to come to my office at any time to discuss."
After hearing Xu Yun's answer, the academician dropped this sentence with a smile on his face and then turned and left.
When other students nearby saw this scene, they sighed one after another and confided in their friends.
"As you have seen, even Xu Shen has to spend a lot of time and diligence in studying materials chemistry. Even the professors and academicians of the college have to pay attention to Xu Shen at all times for fear that there is something Xu Shen does not understand."
"For ordinary people, if they want to learn well, it will be ten times or a hundred times more difficult."
"The major I have chosen now was based on what I had in mind. It is truly a sinkhole-level major."
"I regret it!"
Faced with the complaints and accusations from his friends, the other party was somewhat suspicious, and even more curious about Xu Yun's choice to study materials chemistry.
"It shouldn't be as outrageous as what you said, but didn't Xu Shen come back from the imperial capital saying that he would write a thesis and not accept interviews? Why did he suddenly come to our college to study materials and chemistry?"
"How would I know? Maybe I like materials chemistry." The classmate shook his head and muttered.
Perhaps because he was really surprised, and because Xu Yun was usually approachable and easy to communicate with, the other party finally chose to speed up and catch up.
After lining up with Xu Yun again, he took the initiative to ask.
"Hello, senior."
"Can I ask, senior, why you put aside your thesis to study because you like materials chemistry?"
After Xu Yun replied to the academician in the field of materials, he was about to meet up with Chen Shihe and drive to the station. Suddenly he saw a gentle junior next to him and asked him a question. Although he was a little surprised, he still responded in order not to waste time. Finished sentence.
"I am indeed interested in materials chemistry. As for the paper you mentioned, it should be the proof of Goldbach's conjecture. As expected, you should be able to retrieve this paper now."
After saying that, without waiting for the other party to respond, he continued to walk away quickly.
After hearing the answer, the junior froze on the spot, with a look of shock on his face.
"The paper has actually been published?"
"so fast."
In any case, he never imagined that the paper could be written and published so quickly.
I recall the experience of publishing my paper for the first time and waiting for half a year to be called back for revision.
Suddenly I felt like crying.
He shouldn't have asked the question in the first place.
In the eyes of ordinary people, this may be something that cannot be accomplished in a short time, but to the god of learning, it will only appear easy.
But he figured it out a little late.
Looking at Xu Yun's figure quickly disappearing from sight, he suddenly thought of something and hurried towards the dormitory.
For this kind of world-class paper, even if you don't do much mathematics research, you must take a look.
Xu Yun is not surprised at all that the paper on the proof of Goldbach's conjecture can be published so quickly. On the contrary, it will be even more strange if the delay is too long.
So after receiving the email from Hofer, he took a casual look and put it there.
According to Hofer's explanation, after receiving the paper, the Annual Journal of Mathematics immediately organized experts in the field of number theory to review and demonstrate it, and tried to publish it in the journal as quickly as possible while ensuring rigor.
In addition, since this paper additionally talks about topological group theory, 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 research on number theory by mathematicians and people around the world.
…
Compared to the calm on the Peking University campus, the mathematics community is now in a state of carnival because of the publication of Xu Yun’s paper.
Many mathematicians gave extremely high evaluations after reading the paper.
It may also be that some of the steps in the paper have already been written down at a conference of mathematicians, coupled with the explanation of topological group theory, which makes the voices questioning the proof process very small.
Much better than when Hodge's conjecture was proven.
This is equivalent to the mathematical community recognizing his proof process, and at the same time, it means that the famous problem in number theory, Goldbach's conjecture, has been completely solved.
At the same time, in a study room in a certain community, Zhang Yitang, who had returned to China, was carefully studying the latest issue of the Mathematics Annual that he had just received, hoping to find his own inspiration from Xu Yun's paper.
After having a simple exchange with Xu Yun, he always felt that the topological group theory proposed by Xu Yun was also the key to his proof of twin prime numbers.
Now that topological group theory has been successfully perfected and has been actually applied to Goldbach's conjecture, he is more hopeful that perhaps the twin prime numbers he has studied for so long will finally have results. Because of this matter, he even turned down the mathematicians conference and spent most of the time shutting himself in his room to study it carefully.
Not knowing how much time had passed, he slowly put down the journal and stretched out his hand to rub his eyes and temples.
Although he looked a little tired, his eyes were shining, and his whole body seemed to be extremely energetic.
"This direction is indeed the right one. As long as I continue to study along the lines of topological group theory, I will definitely be able to thoroughly prove twin prime numbers."
"It's really awesome and admirable that he can create such a wonderful and novel theory."
While muttering in a deep voice, he immediately took out the draft paper on the table, picked up the pen and continued to calculate.
The same situation has happened to other mathematicians. It is conceivable that it will not be long before a large number of number theory problems have been solved and proven, which will bring the development of mathematics into the best era.
It is also worth mentioning that after the paper was officially published, many well-known mathematical institutes of universities in the world publicly extended invitations to Xu Yun, hoping to have academic exchanges or even join them.
On the contrary, the Institute for Advanced Study in Princeton seemed very low-key this time. It was obvious that they knew Xu Yun's choice through the last exchange.
Unfortunately, Xu Yun, who was driving to the station with Chen Shihe at the moment, did not 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 returned from overseas after participating in the conference, the most important thing for him right now is to complete the task and get the reward.
Strive to produce an automated intelligent modular robot as soon as possible, so that you will not waste time running around.
