From top stream to scholar

Xie Qing complained frantically on the sidelines that in Huaguo in 2000, "princes and generals should have kindness", and now foreigners are still superstitious about blood blood and surnames.

"It's clear at a glance that his future mathematics achievements will not be low." Faltings seemed not to notice the subtle changes at the dinner table, and he was still talking.

Everyone looked at me and I looked at you, and laughed awkwardly.There was nothing wrong with Faltings. Yu Wanzhou was really teaching Yu Chuwei mathematics in her free time, but Yu Chuwei was just curious after all.Whether he wants to study mathematics in the future is really up to him.Yu Wanzhou is an uncle, and it is impossible for Yu Chuwei to make a decision.

To be honest, let alone Faltings, a foreigner who believes in the theory of bloodlines and aristocracy.Even in Huaguo, although he didn't value blood so much, his uncle was a top mathematician, and Yu Chuwei estimated that the pressure was quite high.

It is not easy to surpass a top mathematician who has solved several Millennium Prize puzzles and won the Fields Medal.

Faltings changed the subject, "Yu, have you thought about what to study next?"

"Probably because of Yang-Mills' existence and quality gap." Yu Wanzhou said humorously, "I plan not to distribute the prize money of the Millennium Prize problem to other people."

"It involves quantum mechanics, no problem?"

"Of course there is no problem." Yu Wanzhou spread her hands and said, "However, this subject has not yet started to collect materials. If we want to solve the problem, we will have to wait until next year or the year after at the earliest. If it is later, I don't know how to solve it." How long will it take to untie it?"

"As long as you have a topic, I really believe in your research ability." Faltings said, "I have never seen someone like you. The research ability is too strong. Almost all mathematical problems are too difficult for you." It's easy."

"As if you were born for mathematics!" Faltings sighed.

At this sentence, Professor Chen Yuan and Lin Wei next to him both nodded slightly. They both thought that Yu Wanzhou was born for mathematics.The ability to solve mathematical problems is even more monstrous than monstrous. I never imagined that there would be such a talent in Huaguo.

After dinner, Yu Wanzhou sent her sister and sister-in-law back first.Then I visited Princeton University for a while with Professor Chen Yuan and Faltings.Finally, he went back to his room. Tomorrow he had another day to rest, and then he was going to defend his graduation thesis, and he was going to defend his graduation thesis with the mathematics authorities who came from various countries.

Yu Wanzhou felt very stressed, and Lin Wei asked Yu Wanzhou to pay attention to himself and not to be too stressed.That's what I said, but how can there be no pressure, this is a special graduation thesis defense.

On the day of the graduation defense, it was held in the academic lecture hall. Yu Wanrong and Wu Tong arrived at the academic lecture hall very early, saw Yu Wanzhou sorting out his things, and said to Yu Wanzhou, "Xiaozhou, come on, You can do it for sure."

Wu Tong also said to Yu Chuwei, "Chu Wei, cheer up little uncle."

"Come on." Yu Chuwei spoke in a childish voice, making Yu Wanzhou laugh, "Sister-in-law, Chu Wei is going to kindergarten, right?"

"No, I'm already in kindergarten." Wu Tong said with emotion, "Time flies so fast, Chu Wei is already in kindergarten."

"I'm still waiting for you to pick up Chu Wei after you go home." Yu Wanrong said with a smile, "If you can graduate this time, you should be able to rest for a while when you go home, right?"

"You should be able to rest for a while." Yu Wanzhou said with a smile, "Don't worry, I will definitely pick up Chu Wei." Yu Wanzhou was pinching Yu Chuwei's face when Professor Langlands came in and told Yu Chuwei Wanzhou nodded and said, "Yu, are you ready?"

"Ready." Yu Wanzhou nodded. Next, professors and scholars entered the academic lecture hall one by one.

Yu Wanzhou stepped onto the podium, took a deep breath, and began to elaborate on her thesis with a pen in hand.While speaking, he kept writing formulas on the blackboard.The professors below watched Yu Wanzhou's performance quietly, whispering to each other.

Yu Wanrong and Wu Tong couldn't understand again, their whole heart was in their throats, and the heart was beating non-stop, especially worried that Yu Wanzhou would be picked on by others.

Yu Wanzhou, who originally felt a lot of pressure, arrived at the scene and faced more than 100 academic authorities and professors from all over the world, but she was much calmer.

"Yu, I have a question." Suddenly a professor stood up and questioned Yu Wanzhou's calculation just now.

Yu Wanzhou carefully repeated the calculation just now, and the professor nodded slightly and sat down.Then Yu Wanzhou continued to explain, because the NP-complete problem itself has a lot of pages, which can reach hundreds of pages, which is almost the thickness of a book.

There must be endless debates in one day. At the end, Professor Jaffe stood up and said, "Let's stop here today. Do you have any questions for this part?"

Everyone looked at me and I looked at you, and shook their heads.There is nothing wrong with them about the previous part.

Seeing the professors leave one by one, Yu Wanrong breathed a sigh of relief, "Wanzhou, have you finished your defense?"

"How can it be so fast." Yu Wanzhou said with a wry smile, "I don't know how long it will take to defend." He took out his thesis and said, "Today I will talk about more than 30 pages, and this thesis has a total of 100 pages. More than [-] pages, and starting tomorrow because of more and more difficult reasons, the explanation will be more detailed. Today I explained it in a rough way, and just like that, you have seen dozens of professors come to ask questions.”

"Some people are purely arguing." Yu Wanzhou shook her head and said, "I think this graduation defense may take half a month, and it may take a week at the earliest."

"Huh?" Both Yu Wanrong and Wu Tong were startled by Yu Wanzhou's graduation defense, "Is your graduation defense at Princeton University so difficult?"

"Not all of them." Yu Wanzhou said with a sigh, "I'm the only one, because I haven't been to Princeton University for a long time, and I want to graduate so soon, which is not in line with the rules. It will take five years for me to graduate."

Yu Wanrong patted Yu Wanzhou's shoulder, "Xiaozhou, you are miserable!"

"No way, if you want to graduate early, you have to pay a little price. Fortunately, today is over, there is no problem with this part." Yu Wanzhou pouted, "Sister, sister-in-law, let's go eat first."

When she walked to the restaurant, Yu Wanrong answered a phone call, which should be from her brother-in-law.

Judging by the tone and expression of Yu Wanrong's answer, Yu Wanzhou was sure that it was his brother-in-law who called.

Sure enough, after a while, my sister hung up the phone.Said to Yu Wanzhou in disbelief, "Your brother and brother-in-law have arrived in Philadelphia and are waiting for us to pick them up."

"Ah?" Yu Wanzhou froze for a moment, "What's going on?"

"It was said that someone invited them to go abroad. It seems that the professor of Princeton University invited them to go abroad to watch your graduation thesis defense, and then they went to go abroad to go through the formalities. It was really done."

"Can it still be like this?" Yu Wanzhou still hasn't figured out who did this for him.It was Lin Wei who ran over and said, "Junior Brother Yu, are you going to Philadelphia?"

"Um, which immortal brought my brother and brother-in-law here?" Yu Wanzhou looked at Lin Wei, obviously Lin Wei knew about it.

"Who else is there besides your professor?" Lin Wei said with a smile, "Professor Weiteng said, let your family see the scene where you are being bullied, and you can't let him be seen by your family alone. You bully him."

"Then I have to thank Professor Weiteng later." Yu Wanzhou said to his sister-in-law and sister, "Then I'll pick up my brother and brother-in-law first, are you waiting?"

"Okay." Yu Wanrong nodded, and Xie Qing ran out from nowhere, and said to Yu Wanzhou, "Brother Yu, go, I can translate if my sister doesn't understand anything later."

Yu Wanzhou frowned, "Why, do you want to come to Princeton University?"

"I heard that brother will be a professor at Princeton University in the future. Isn't this a flattery?"

Yu Wanzhou was amused by Xie Qing, "Okay, then I'll pick up my brother and brother-in-law first."

Lin Wei was driving, and Yu Wanzhou called Yu Wanshen, "Brother, are you at the Philadelphia airport?"

"Correct."

"Just wait, it will take more than an hour for us to come here, and it may take a while to arrive."

"It's okay, take your time, your brother-in-law and I will wait." Yu Wanshen thought for a while and said, "By the way, the professor Wei who contacted us before, didn't I meet him before, why is he you?"

"Professor Wei Teng is my doctoral supervisor." Yu Wanzhou said dumbfoundedly, "You dare to come to the United States without asking clearly. You are not afraid of being deceived."

Yu Wanshen said with a smile, "Have you forgotten what your brother does? Slow down, don't worry, it's okay, your brother-in-law and I will wait."

"En." Yu Wanzhou hung up the phone and said to Lin Wei, "My brother said that they are waiting for us at the Philadelphia airport."

After arriving at the Philadelphia airport, Yu Wanzhou found Yu Wanshen and Jiang Xi, waved to them and said, "Brother, brother-in-law."

Yu Wanshen said to Yu Wanzhou with a smile, "Xiao Zhou, it's not bad." Jiang Xi rubbed Yu Wanzhou's hair beside him, "Jiang Yi said that he can't come, but don't lose the chain."

"Didn't you start your graduation thesis defense today? Are we late?"

"It's not too late." Yu Wanzhou said with a smile, "Tomorrow will be even more exciting, you just have to see how these professors and scholars can challenge me."

"I heard that Xiaozhou likes to bully his professor, doesn't he?"

"This is my senior brother, Lin Wei."

"Hi, please take care of the boat."

"It's okay, it's okay." Lin Wei said while letting go, "It's time for dinner, I'll take you to Princeton University, have dinner first, and then talk about these things."

"Okay." Yu Wanshen and Jiang Xi didn't bring much. Sitting in the car, Yu Wanshen and Jiang Xi looked at the scenery on both sides curiously.

An hour later, they arrived in Princeton.After parking the car, Yu Wanzhou took his brother and brother-in-law to find his sister-in-law and sister, and Lin Wei was naturally invited to have dinner with them.
