From top stream to scholar

The next day, Princeton University.

Yu Wanzhou's graduation ceremony, this is the most special doctoral graduation ceremony held by Princeton University.Only Yu Wanzhou's family and dozens of professors participated.There are also some professors who have left after defending their graduation thesis yesterday, and they have other things to do.Including Professor Chen Yuan, because Hua Guo still has a lot of things waiting for him.

Instead, Xie Qing stayed to watch his brother's graduation ceremony.

When Ms. Zhang presented the graduation certificate to Yu Wanzhou, she said with a smile, "Dr. Yu, congratulations. From now on, you are the real Dr. Yu."

"Thank you for your teaching, Ms. Zhang."

"Dr. Yu, would you like to be a professor of mathematics at Princeton University?" Ms. Zhang took out the letter of appointment with a serious face and said, "This is a letter of appointment from Princeton University. Dr. Yu is invited to be a full professor of the Department of Mathematics at Princeton University. Letter of Appointment for a Student Instructor."

Yu Wanzhou solemnly announced the letter of appointment, "I am very happy to be a professor in the Department of Mathematics of Princeton University. There is no place more suitable for me than Princeton University. If there is one - then it must be my motherland!"

Ms. Zhang said with a smile, "Then congratulations, Dr. Yu, from now on. You are not only a doctorate in the Department of Mathematics of Princeton University, but also a professor of mathematics and a doctoral supervisor in the Department of Mathematics of Princeton University."

"I am very grateful to Princeton University for giving me this opportunity to prove my ability. I also want to continue to have academic exchanges with my professor Dr. Witten on physics issues. I will not disappoint this opportunity."

Professor Witten smiled and looked at Yu Wanzhou who received the letter of appointment from Princeton University on the stage, and the professors and scholars below were also applauding non-stop.What a joke, it's unprecedented, Yu Wanzhou is probably the only one who can be a full professor after graduating from a Ph.D.

Others, no matter how talented they are, start as associate professors and gradually become full professors and doctoral supervisors.And Yu Wanzhou directly skipped the associate professor and served as a mathematics professor and doctoral supervisor at Princeton University from the beginning, which is really shocking.But in retrospect, it seems quite reasonable.

It seems reasonable for Yu Wanzhou to graduate early and serve as a professor in the Department of Mathematics at Princeton University.

At this time, Deligne stood up and said to Yu Wanzhou, "Dr. Yu, would you like to accept the appointment of the School of Mathematics of the Princeton Institute for Advanced Study and become a professor of the School of Mathematics of Princeton University?"

"I am willing." Yu Wanzhou seemed to be open to all comers, but he knew that he needed the learning environment and atmosphere of Princeton University now, and needed this kind of communication that could stimulate his inspiration.

"Then congratulations, Dr. Yu, the Princeton Institute for Advanced Study will send you an official document. After your vacation is over, you can enter the School of Mathematics of the Princeton Institute for Advanced Study with the paper file of this email."

"Thank you, Mr. Deligne." Yu Wanzhou breathed a sigh of relief.

Ms. Zhang said with a smile, "Next, in order to celebrate Dr. Yu's graduation, there will be a party in Nassau Building tonight, and I sincerely invite everyone to join this party."

The crowd gradually dispersed. Yu Wanzhou held the letter of appointment and said to Ms. Zhang, "Ms. Zhang."

"Oh? Professor Yu, is there anything else you want to say?" Ms. Zhang smiled, "You are already a professor in the Department of Mathematics at Princeton University, and you can just register in the Nassau Building later. However, maybe this year you There will be no students, the students have been selected in the first few months."

"That's exactly what I want to tell you." Yu Wanzhou pondered for a while, "I've been very tired recently, and I want to take a longer vacation, maybe in March next year, when I'm going to Princeton University. "

"There is no problem at all." Ms. Zhang didn't even say a word, "You really should take a good rest. After all, you have solved three millennium award problems in a row. Maybe you should go on a trip, or talk about it with all your heart. Love or something."

Yu Wanzhou said with a smile, "Ms. Zhang, I have just come of age."

"That's right, but when you arrive at Princeton University next year, you will be 19 years old, won't you?" Ms. Zhang said with a smile, "Okay, Professor Yu, congratulations on becoming both a professor in the Department of Mathematics at Princeton University and a professor at Princeton University. Professor at the School of Mathematics at the Institute for Advanced Study."

"You should probably go to Nassau Building to register now. By the way, I would like to remind you that you must not be absent tonight."

"Okay." Yu Wanzhou nodded. After Ms. Zhang left, he smiled at his family and said, "It's done, I graduated with a doctorate."

"Come, come, take pictures!" Yu Wanshen happily took pictures with Yu Wanzhou who was wearing a doctor's suit, and her brother-in-law and sister also happily took pictures with Yu Wanzhou.Finally, a family photo came, and Yu Wanzhou said to them, "Brother, sister, I just agreed to Princeton University."

"What?" Yu Wanshen said while looking at the photos he took, "What did you promise? Didn't you all graduate?"

"They hired me as a professor and doctoral supervisor in the Department of Mathematics of Princeton University, and I agreed." Yu Wanzhou said with a smile, "I'm going to Nassau Building to register now."

"Ah?" Jiang Xi was stunned, "Professor, or a doctoral supervisor?"

"Aren't those brothers before you all associate professors? Why are you a professor?"

Yu Wanzhou said with a smile, "I might be better than them."

"You son of a bitch." Jiang Xi patted Yu Wanzhou's head, "How many more years do you want to stay here in Princeton?"

"En." Yu Wanzhou put away her smile, "The academic atmosphere and academic exchanges here are very suitable for me. I think it will be better for me to return to China after staying here for a few more years."

"You can make up your own mind about these things. We don't know very well. What's going on? You told us, but we don't know too well."

"But I took a long vacation, and I won't be back at Princeton until March next year." Yu Wanzhou happily pulled Yu Chuwei's face and said, "Wait until September when uncle comes to pick you up every day, okay?"

"Good duck, uncle." Seeing Yu Chuwei's milky voice, Yu Wanzhou wanted to continue pinching Yu Chuwei's face.

"Brother, you wait here first, I'll go to Nassau Building to register." Yu Wanzhou looked at Xie Qing who was on the side and said, "Thank you, Junior Brother, help me look after my family, I'll go to Nassau Building first."

"Okay, Professor Yu, don't worry, I will definitely finish everything."

"You flatterer." Yu Wanzhou looked at Xie Qing with a smile and said, "Any idea?"

"Forget it, after I read my senior's graduation defense, I found that Professor Chen Yuan's side is better."

Yu Wanzhou shook her head and went to Nassau Building to register.

After he registered, he went back to the dormitory to pack his things. Starting tomorrow, he will not be a student of Princeton University. Why don't he go to the house rented by Brother Lin Wei next year for help?Forget it, let's not trouble the senior brother, Yu Wanzhou thought about it, let the senior brother rent him a house next year.

It will be finalized this year, the money will be paid first, and then he will come to live directly next year.

He also called Xie Qing and asked him to bring his family to the dormitory to find him.When Xie Qing led Yu Wanshen and the others over, Yu Wanzhou was packing up several boxes.

Yu Wanshen opened the door, saw Yu Wanzhou so many things, and helped Yu Wanzhou tidy them up.

"Take so many things back?"

"No, I'll leave it with Brother Lin Wei later, and I'll have to use it when I go to Princeton University next year." Yu Wanzhou said with a smile, "I have to return the key to the school."

After tidying up, he worked hard for most of the day, and finally put Yu Wanzhou's things at Lin Wei's house.Sitting at Lin Wei's house for a while, Yu Wanzhou dragged Lin Wei to Princeton University in the second half of the year to find a house for him. In the end, the house next to Lin Wei was the best.Lin Wei patted his chest and said there was no problem.

In the evening, Yu Wanzhou took his family to the party.

The brightly lit party was held in Nassau Building, the most famous building of Princeton University. Ms. Zhang raised her glass and said, "Let us celebrate Dr. Yu Wanzhou's Ph.D. Ph.D. became a professor at Princeton University."

"Dr. Yu, please!"

Yu Wanzhou picked up the drink cup and said to Ms. Zhang, "Thank you."

"Thank you all for your affirmation!"

After a few drinks, Yu Wanzhou chatted with the person next to him about academic issues.Yu Wanshen and Jiang Xi were quite curious. It's not that Jiang Xi had never attended a party before, it was really the first time to attend a party that was almost full of foreigners.As for Yu Wanshen, it was indeed his first time attending a party.Looking at the party curiously, watching Yu Wanzhou smiling and chatting with others at the party, he found that his younger brother seems to be able to adapt to this environment.

"Senior brother Lin, do you want to listen to the gossip?" Yu Wanzhou raised his glass and said to Lin Wei.

"Gossip?" Lin Wei raised his eyebrows, "What news?"

"What news?" Xie Qing, who got involved, ran over curiously, "Senior brother, tell me quickly, what news?"

"It's from the IMU." Yu Wanzhou said in a low voice, "Brother, you have the Ramanu Gold Award this year."

"How do you know the news from the IMU?"

Yu Wanzhou smiled mysteriously, "There are people above, do you believe it?"

"There are people up there." Lin Wei gave Yu Wanzhou a disgusted look, "Professor Chen Yuan told me about it, but I have to wait and see. Where will this year's Ramanu Gold Award be held?"

"Probably in the capital." Yu Wanzhou said uncertainly, "Why, brother can't bear it anymore?"

"Don't talk nonsense." Lin Wei tapped Yu Wanzhou on the head.

Yu Wanzhou laughed and chatted with Lin Wei for a while, and then continued to exchange academic issues with other professors.

After the party, Yu Wanzhou went directly to Lin Wei's house to sleep.He has already handed over the key to the dormitory, and there is no place to sleep.Fortunately, the house that Brother Lin Wei rented was quite big.

The next day, I returned to China from Philadelphia with my family.
