God of black technology

[Ping An Yucheng: my country's first Abel Prize-winning scholar [Picture] [Picture] is the little brother of Yucheng! 】

[Is the current official time taking advantage of the heat like this?Although the younger brother is from Yucheng, he is still a professor at Princeton? 】

[Pingan Yucheng: But he is from Yucheng! 】

[No problem, I support you!Ha ha ha ha……】

[This person from Yucheng is crying secretly, everyone is also 20 years old, and they are also from Yucheng.Others are Princeton professors, and I'm just an undergraduate salty fish. 】

[I don't know when it started, but this professor seems to have become an Internet celebrity professor.But it can be seen that the professor has not been affected.Ordinary people would have made their debut long ago to make money, but this professor can still appear in front of the public in such a down-to-earth manner, it is very heartfelt. 】

[ummmmm... This professor made his debut before, but later felt that the entertainment industry was not fun, so he went back to continue his studies.Everyone knows what happened afterwards. 】

【Is this... the world of the strong?Can it still be like this? 】

[After searching for this great god, I really can't believe that this great god was an idol before.I think I may be a little mentally confused, and I can't connect this great god with idols at all. 】

【Me too, I'm drunk... He really was an idol, and he also made a TV series, although it's a sand sculpture TV series, and the acting skills of the great god are so exaggerated.But the face is really pretty, I still have a doubt, such a powerful top scholar, why his hair is still so lush? 】

[I'm heartbroken, I'm a scientific research dog and I'm going bald, why is Daniel's hair still so lush.This unscientific……】

[Another crazy one, someone drag it down and bury it! 】

[It's a pity, if such a great master teaches in the United States, if he can return to Huaguo, he might be able to train many talents for Huaguo. 】

[Yeah, I also feel a little pity.However, this is their own choice.Didn't this great god get attacked by fans last year?I guess I am quite disappointed with Huaguo.Although the great god didn't say that, I think he must have thought about these things in his heart.It's quite chilling, people are engaged in scientific research day and night.Isn't it just a popular science program?He was also blackmailed by a group of idiots, and even went to Princeton University to complain. 】

[I know about this, but several people have been sued in court, right?But I think the Great God must have been very disappointed with Huaguo at that time, it was all a bunch of stupid criticisms. 】

Wang Yun, who was popular on the Internet, was resting after eating. Wang Zhenbei and Su Chen had already left the house, and only Shen Cheng and Commissar Lin seemed to be discussing work matters.

Wang Yun didn't know that he had become popular all over the Internet, although it was not like he had never had a sense of presence before.But people will always forget, especially scientists like Wang Yun who don't often appear in the eyes of the public.Maybe when you see it, you will say a few words that you are so handsome, but after a few days, you will completely forget it, and there will be new people to pursue.

But when Wang Yun appears again, the public will still have some impressions.

I remember Wang Yun, plus Wang Yun was originally young, and he was the first to win a very famous international award in the academic circle who seemed very tall.

Naturally, it will cause a carnival on the Internet, which is completely spontaneous.When seeing Wang Yun wearing slippers again, netizens became excited instantly. It turns out that scientific research workers are as down-to-earth as everyone else.It's not like a star, it feels like the whole person is floating in the sky.

What's more, in terms of contribution, the contribution of scientific researchers is much greater than that of stars.

When netizens were carnival, Wang Yun was not idle. It is impossible for him to study the existence and quality gap of Yang-Mills now.But you can also consult more books, especially literature and materials on quantum mechanics.

By the time Commissar Lin left, it was already past one o'clock in the morning, his mother had already gone to bed, and Wang Yun was still looking at the documents.Shen Cheng, who originally wanted to go back to his room to sleep, saw that the lights in Wang Yun's room were still on, and opened the door gently, and he could see Wang Yun looking at the materials from a distance.

Shen Cheng said softly, "Xiaoyun, it's almost time to go to bed."

"Okay, I know." Wang Yun replied, "I'll go to bed later."

Shen Cheng smiled and closed the door gently.He knew that once Wang Yun started serious research, it would be impossible for him to go to bed or rest quickly.

So Shen Cheng didn't try to persuade Wang Yun too much, but just closed the door and went back to his room.

It is not easy to understand quantum physics. The literature Wang Yun is reading now is about vectors. Generally speaking, vectors are basic concepts in many natural sciences such as mathematics, physics, and engineering science. , refers to a geometric object that has both magnitude and direction, and is named because it is often marked with an arrow symbol to distinguish it from other quantities①.

In mathematics, a vector is also often called a vector, that is, a quantity with a direction.And use a more abstract vector space (also known as linear space) to define, and define the vector concept with physical magnitude and direction, you need to introduce the Euclidean space with norm and inner product②.

That is, if you want to understand the vector concept in the physical sense, you must learn to use norms, inner products, and Euclidean spaces at the same time.

Wang Yun has been in contact with these fields before, so it is very easy to understand.

After reading the information for a while, he put down the book in his hand, stretched his waist and prepared to sleep.

The computer was turned on, Wang Yun opened the email and found that Lu Cheng had sent him an email.At this time, why did Lu Cheng send him a message?Wang Yun curiously opened the email, and found that Lu Cheng had asked for leave for him. Because of some family matters, he had to return to China for a few days, which may lead to a delay in research.

Lu Cheng had shown him some formula calculations on Hilbert space before, but on Banach space, Rong Lei's research progress was much slower than Lu Cheng's research, resulting in a slower overall speed. Some.It is precisely for this reason that the research on Hilbert space may not necessarily be completed this year.

Originally, Wang Yun's plan was for the two of them to graduate with a master's degree within this year, and a Ph.D. degree in at most two years.With full play and full calculation, when he solved the existence and quality gap of Yang-Mills, he was able to bring the two back home.However, the specific situation may not be as optimistic as estimated.

After reading Lu Cheng's letter, Wang Yun directly sent an email to Lu Cheng allowing him to go home, and asked him if he needed his help.But Lu Cheng didn't reply to Wang Yun, probably because of some unspeakable things.Is it a family matter?Wang Yun was sitting in front of the computer pondering, the door of the room was gently pushed open again.

Turning his head to look at Shen Chengcheng standing by the door, before Shen Cheng could speak, Wang Yun said first, "I have something to ask you."

Shen Cheng was taken aback, then nodded, walked into the room and asked, "What's the matter?"

"I just received an email from my student." Wang Yun said earnestly, "He said he had something to do at home, and he seemed a little anxious to read the content of the email, but his parents are in the United States, but he said he would go home."

"Does he have no relatives in China?" Shen Cheng first thought of being kidnapped, but then something went wrong.Wang Yun has not yet returned to China, even if he is kidnapped, there is probably nothing he can do.And being able to become a graduate student at Princeton University, I am afraid that I am not so stupid as to ask for help from such a distant mentor.

"Of course there are relatives in China." Wang Yun spread his hands and said in a deep voice, "I want to say, if there is really something at home, it is not convenient for us to help him? Or, instead of going to Princeton University, I will go to Princeton University first. Do something for him or something?"

"That depends on what it is." Shen Cheng smiled. Wang Yun's interests are almost all in scientific research. Although he is not bad in dealing with people, he can't be said to be good either.It's not his fault that he can't make up his mind about these things, after all, he's only 20 years old.Most of the time is spent dealing with numbers.

Wang Yun rubbed his brows, he should have received my reply by now.

"Where was he before?" Shen Cheng said in a deep voice, "in Princeton?"

"It must be in Princeton."

"I guess I sent you a message in such a hurry, I'm afraid it was on the plane." Shen Cheng patted Wang Yun's shoulder, and said comfortingly, "It should be something happened to the relatives in China, I think I should tell you later Make it clear."

"Wait a little longer. By the way, you have two graduate students. Why don't you ask if the other one knows what's going on?" Wang Yun is a little confused now. Hearing what Shen Cheng said, it's okay I really remembered that I still have a graduate student, Rong Lei.This guy should know about Lu Cheng.

He nodded, "Then I'll call Rong Lei first."

"Rest early." Shen Cheng was in a good mood. This was the first time Wang Yun asked him about these things a few months ago.This was a good start. After closing the door, Shen Cheng returned to his room.

Wang Yun picked up the phone and called Rong Lei.

After a while, Rong Lei's voice rang on the other end of the phone.

"Hello, Professor Wang. Are you going back to Princeton?"

"No." Wang Yun asked, "What's the matter with Lu Cheng? He sent me an email to ask for leave. You live with him. You should know what's going on, right?"

"This..." Rong Lei recalled carefully, "I don't know the specific situation, but today he suddenly received a call, which seemed to be from China. Then he said something happened at home, so... …Anyway, I didn’t make it clear to me, saying that I will send you an email when I arrive at the airport.”

"He should be on the plane back home by now."

"Okay, I see." After Wang Yun hung up the phone, he was still a little uneasy.But there is no other way, Lu Cheng is already on the plane, so we can't call him now.

He could only wait for Lu Cheng to arrive in China before contacting him.
