God of black technology

The next day, Wang Yun arrived at the agreed place early.Wang Zhenbei came here with Wang Yun. Looking at the scenery outside the window, Wang Zhenbei said with emotion, "Isn't it just an interview? It doesn't need to be so grand, right?"

Wang Yun glared at Wang Zhenbei, "What do you know?"

"Okay." Wang Zhenbei shrugged his shoulders, "I don't know what you scholars are thinking."

Just as he was talking, Lu Cheng walked into the store slowly.Coming to Wang Yun's side, Wang Zhenbei looked at Lu Cheng and said, "This young man looks pretty good."

Wang Yun glared, then said in a low voice, "What nonsense are you talking about, this is my senior."

ummmmmmm...

Isn't it embarrassing that your senior is going to be your graduate student now?

To be honest, the moment Wang Yun saw Lu Cheng, he was indeed a little embarrassed.Anyway, Lu Cheng was his senior before.Now that he is applying for his graduate student, it feels a bit speechless.

"Professor Wang." Lu Cheng spoke first, staring at Wang Yun.In fact, when he chose Princeton professors, he did choose professors of mathematical physics.Professor Weiteng was his first choice, but he always felt that he might not be able to become his graduate student if he chose Professor Weiteng.

When I looked at the official website of Princeton for the last time, I suddenly refreshed the list of professors of mathematical physics.

In the list of professors, he saw a familiar name.And this familiar name ranks very high, he has always thought that his junior is very powerful.But I didn't expect to become a professor at Princeton in just over a year or two.At this speed, the rocket is almost unable to catch up.

He made a decisive decision and directly submitted his application.

So, now Lu Cheng appeared in front of Wang Yun.

Lu Cheng didn't have any burdens, and Wang Yun was indeed his junior. There was nothing wrong with that.But he is capable and can become a professor at Princeton, so there is nothing wrong with calling him a professor.

What's more, if I am lucky enough to be Wang Yun's graduate student, I will always call him a professor.If you can't even pass this level, it's a joke.

"Sit down." Wang Yun pointed to the seat opposite him and said.

After Lu Cheng sat down, Wang Yun looked at him, was silent for a while, and then said, "I won't say much else. I think you are very clear about what to say and what not to say during the interview."

"Besides, I've known you for a long time." Wang Yun paused when he said this, "The rest of the red tape will be skipped, and I'll just ask you a question. What do you think of my theory?"

Lu Cheng was silent for a while, he had imagined many situations.The situation where Wang Yun cut straight to the point was also something he had thought of.So he didn't panic.

As for Wang Yun, he wasn't worried at all that Lu Cheng's physics would be bad.After all, the physics department of Peking University is the best in China, and the best students in the physics department are among the best in the country, so naturally Wang Yun has nothing to worry about.But it is impossible to just talk about the interview, and it is definitely necessary to ask about professional knowledge.

Therefore, Wang Yun directly asked Lu Cheng what he thought of his theory.

【…………

U(xτ)^n=u(δ)

δ=kx+hy+ωt+δ_0

…………

With the help of the homogeneous balance method, let the specific form of the proposed solution be

u(δ)=a_0+a_1φ(δ)

…… 】

Lu Cheng said while gesturing on the table with his hands.Wang Zhenbei couldn't understand and felt a little bored.Wang Yun listened little by little, while thinking, while listening to Lu Cheng continue to explain.

After a while, Lu Cheng finally finished speaking.

Wang Yun raised his head, looked at Lu Cheng and said, "Okay, if there are no accidents, I hope to see you at Princeton University in September."

Speaking of this, Wang Yun paused, "Be sure to ask where my office is, of course, I don't know exactly where my office is now." When he said this, Wang Yun shrugged his shoulders, "You After you go there, you can draw up your own topics, and I can ask you to help you draw up topics.”

"Professor." Lu Cheng looked at Wang Yun and asked with an inquiring gaze, "May I know the subject you need to study in the future?"

"Of course." Wang Yun smiled. "My future subject is Yang-Mills theory. Why are you interested? When you get your Ph.D., maybe I can let you participate in the experiment. No." Wang Yun shook his head, "You still need to settle down. Although your mathematics is not wrong, it is obvious that you still have many deficiencies in mathematics. The same is true for physics. Therefore, Lu Cheng, you still need to work hard."

"Thank you, Professor." Lu Cheng breathed a sigh of relief and stood up, only to realize that his legs were a little weak.

What a joke, facing the top-ranked professors in Princeton, it's strange that he doesn't have weak legs.Touching the cold sweat on his forehead, Lu Cheng took a breath before continuing to walk outside the door.

Wang Zhenbei looked at the back of Lu Cheng leaving, and said with curled lips, "This guy, his mental quality is not very good. He stuttered several times just now, and he almost couldn't continue."

Wang Yun smiled and said nothing, stood up and walked out.Naturally, Wang Zhenbei followed Wang Yun and left the coffee shop, and stayed in the capital for several days.Wang Zhenbei will definitely not be able to go home. This guy has to go to the army for an internship during his vacation.Wang Qiuyang packed up and prepared to go back to Yucheng with Wang Yun.

Sitting on the plane, Wang Qiuyang yawned and said, "I don't think I can continue to be decadent this summer vacation."

"Oh?" Wang Yun raised his eyebrows, "Then what are you going to do?"

"Well..." After thinking for a while, he said, "I will work hard and get a bachelor's degree from Princeton within one year."

"Well..." Wang Yun pondered, "Princeton's bachelor's degree is not so difficult, Qiuyang, you can figure it out."

After returning to Yucheng, the two got into the car quickly because their second uncle picked them up.

The second uncle looked at Wang Yun and said with a smile, "Xiaoyun hasn't returned to China for almost a year, right? How is it going abroad, are you still used to it?"

"It's...not bad." Wang Yun was silent for a while.

"When will you graduate? I heard from Qiuyang that you seem to have already finished your doctorate degree?" The second uncle was also not sure what happened to Wang Yun.Although I often talked on the phone, I just hung up the phone after saying a few words in a hurry.It seems that Wang Yun is a bit busy abroad, and people don't call Wang Yun often when he comes and goes.

After all, the elders thought that Wang Yun was too busy, so they were too embarrassed to disturb him.Coupled with the fact that there was a time difference between that side and this side, contact was even rarer.The only one who has a close relationship with Wang Yun is Wang Qiuyang.

"Already graduated." Wang Yun smiled, "I just graduated in May this year."

"Ah?" The second uncle didn't come to his senses for a while, "Isn't it not long before you got a doctor's degree? Why did you graduate?"

"Just... the doctoral project is finished, and the supervisor allowed me to graduate early." Wang Yun looked at the scenery outside the window, and the second uncle said happily, "So, you won't leave this time when you return to China?"

"No." Wang Yun smiled awkwardly, "Maybe he will have to stay abroad for a few years, and Wang Qiuyang will go there soon."

"???" The second uncle didn't know what happened at all, so he could only ask, "What's the matter, isn't the doctor already graduated? How many years do you have to stay there?"

"Hmm." Wang Yun said shyly, "Princeton sent me an invitation letter to be a professor there, so..."

"What?" The second uncle stared straight, "Professor?"

"Yes, a professor of mathematical physics at Princeton University." Wang Yun scratched his head, but he didn't expect the second uncle's reaction to be so strong. "I thought, I'm also there, I can take care of Qiuyang to some extent, and the learning atmosphere there is not bad, so I want Qiuyang to study there too."

"This is a good thing." The second uncle said with a smile, "I will let Qiuyang study as a graduate student with you in the future..."

"Forget it." Wang Yun shook his head and said, "I'm afraid I won't be able to suppress him. If he works hard enough, he can go to my teacher."

"Second uncle, I told you about my teacher before."

"Yes, yes, yes." The second uncle nodded and said, "That name is Wei Teng, a very famous physicist."

"Edward Witten." Wang Yun said casually, "Professor Witten's physics is very good. It would be a great thing if Qiuyang could study physics under Professor Weiteng's school. Moreover, Professor Witten's Maths is also very proficient.”

"Just like you." Wang Qiuyang sighed.

The second uncle glared at Wang Qiuyang and said, "Why are you sighing? Look at you, and then look at your brother. Your brother is already a professor, and you haven't even graduated from your undergraduate degree. Don't you feel ashamed?"

"Dad." Wang Qiuyang said with a wry smile, "What's there to be ashamed of? How many people can become professors in more than a year? Wang Yun is simply one—" He didn't say the last two. .

He saw Wang Yun looking at him with a half-smile.

Forget it, let's not talk about it.

After returning home, because he did not advance his mother, his mother was not at home.Thinking about it, Wang Yun took out his mobile phone and called Rong Lei.

He and Rong Lei used to communicate by email before, but they have returned to China, so there is no need to be so pretentious, they must contact by email.

I don't know if Rong Lei's mobile phone number has changed, Wang Yun was thinking, and the answer button on the other end of the phone has already been turned on.

"It's Wang Yun?" Rong Lei's voice was pleasantly surprised, "Oh, I forgot, it's Professor Wang now."

"Stop coming." Wang Yun smiled, "I saw the application you handed in."

"Did you see it?" Rong Lei was a little incredulous, "I just tried to submit an application. I think there must be a lot of people who want to study for graduate students with you. Maybe you can't even see my information. You Did you see it?"

"Yes." Wang Yun pondered and said, "You can thank Professor Witten's assistant—Mr. Robert, who passed your information on to me."
