"The above is my thesis. Teachers, do you have any questions?"
School of Mathematical Sciences, in a small academic lecture hall.
Lin Xiao stood on the stage, finished speaking about his graduation thesis, and then looked at the teachers present with a smile.
At a glance, except for the five defending teachers sitting in the first row, the entire academic lecture hall was almost filled with other teachers and professors who came to watch his defense.
Although it is a small lecture hall, it can still accommodate seventy or eighty people. As a result, the teachers who came after hearing the news were all occupied. Some teachers even moved from the next room when they saw that there were no seats.
A few chairs, and then sat in the aisle.
There is no way, for Lin Xiao, a mathematical genius who has become famous in the country and in the world of mathematics before officially entering the school. After entering the school, he directly completed the proof of Goldbach's conjecture. His graduation defense, these
Of course the teachers wanted to come and take a look.
As a result, there are more than 30 teachers in the School of Mathematical Sciences, plus more than 30 teachers in the School of Physics and Chemistry, in addition to school leaders, including the principal, vice president, etc., as well as professors from other schools.
All added up, a total of more than ninety people came running over.
These teachers are basically full professors, and there are only a few associate professors. There are no young lecturers. They will probably be kicked out by other professors who have no positions.
As for the academicians among the more than 90 people, there are more than 20, especially academicians of mathematics and academicians of chemistry and materials. Needless to say, academicians of mathematics and academicians of chemistry and materials also come. Naturally,
It was because of Lin Xiao's paper a few months ago that this genius, who originally belonged to the world of mathematics, became a popular figure in the world of chemistry and materials.
Facing such a scene, Lin Xiaodu felt for a time as if he had returned to his original report on Goldbach's conjecture in the Great Hall of the People.
He is probably the only student in the country who can make such a fuss during his undergraduate graduation defense... He should be more confident and remove this possibility.
After seeing Lin Xiao finish narrating the thesis, the teacher responsible for the defense also needed to ask questions.
As for these defending teachers, they are all academicians.
"Page 5, why is your equation 1 smaller than equation 2?"
An old academician asked with a smile.
Lin Xiao turned to the fifth page of the paper and took a look, then smiled slightly and replied: "This conclusion can be obtained by integrating both sides of [τ1, θ] and using (B)-(C)
.”
Then, he picked up the chalk and wrote the argument process on the blackboard.
"Um."
Seeing Lin Xiao write down the proof process quickly, the old academician smiled and nodded, "Not bad, not bad."
"Thanks."
Lin Xiao nodded to the old academician. This old academician was in his seventies and had been retired for many years. However, he took the initiative to be his defense teacher. Lin Xiao was dumbfounded when he learned the news, but it also showed that he
Pay attention to him.
Then another academician asked a question.
In fact, asking questions is just a process. The defense is to test the students' mastery of their thesis and then find out the flaws. But what could be wrong with Lin Xiao's thesis?
So after the five defending teachers asked random questions, one of the academicians laughed and said: "This paper has been published in one area, and I still have to come to defend it. Isn't it a waste of time?"
This academician is Academician Yuan Ya, the president of the Chinese Mathematical Society. Although he is not an academician of Peking University, he came here as an expert from another school to serve as the defense teacher.
After hearing what Academician Yuan said, several other academicians nodded, stood up with a smile, and clapped towards Lin Xiao.
People in the audience also stood up and applauded.
The applause was, of course, for Lin Xiao’s graduation.
Seeing this young man completing his graduation, they couldn't help but think of what they were like when they graduated. At that time, they didn't have such a big classroom, and how could there be so many people coming to see it.
Looking at Lin Xiao, they all sighed in their hearts, each generation is getting stronger than the last.
At this time, as Lin Xiao's advisor, Xu Ji also stood up and said with a smile: "Classmate Lin Xiao, congratulations on completing all your undergraduate studies with excellent results."
"Thank you, Teacher Xu, and thank you all the teachers for taking care of me."
Lin Xiao had a smile on his face, and then bowed to every teacher present.
At this point, his life has once again completed a stage.
The academicians present also came up one after another and sent their blessings to Lin Xiao. Lin Xiao also shook hands with them one by one and thanked them.
It wasn't until an hour later that Lin Xiao returned to Xu Ji's office.
"Here are your degree certificate and graduation certificate."
Xu Ji handed two certificates symbolizing graduation to Lin Xiao.
Lin Xiao lowered his head and glanced at his ID photo, which looked as handsome as ever.
Is this what Peng Yuyan is like?
Then he accepted the two documents and said with a smile: "I thought it would take a month or two."
Xu Ji smiled and said: "In order to avoid affecting your schedule, you will start preparations after submitting your thesis. It will be prepared for ordinary undergraduates in a month or two. What if someone delays the graduation?"
Lin Xiao: "...that's true."
"Okay, let's do that. Oh, by the way, I have to prepare a graduation ceremony for you later."
"There's no need to bother, right?" Lin Xiao was stunned and couldn't help but say.
"This is too much trouble." Xu Ji patted Lin Xiao's shoulder: "You are the face of our School of Mathematics and Peking University. If we don't even save your graduation photos, then we are
The college has failed in its duty.”
"Think about it. In the future, when people search for the information of the prover of Goldbach's conjecture, they can't even find your college graduation photo. Will others feel very sorry?"
"Also, if someone asks our School of Mathematics to show you your graduation photo from our school, and it is not found, will our school lose face?"
"So let's go together. The principal and others just wanted to take a photo with you."
Hearing Xu Ji's words, Lin Xiao touched his nose, as if... what he said did make sense?
"Are you leaving now?"
"Let's go."
As a result, Lin Xiao was taken to the school's auditorium. As the only graduate in this graduation ceremony, Lin Xiao took a photo with at least ten college leaders and school leaders.
At this point, all the processes are truly completed.
"Okay, then you can come back when school starts next year."
Xu Ji smiled and said to Lin Xiao.
Since it is a joint training program between Peking University and the Ecole Normale Supérieure de Paris, Lin Xiao naturally has to register at Peking University first and then go to Paris.
"Well, then Professor Xu, we will see you next year."
"Okay, goodbye, have a good year."
Lin Xiao waved his hand and left here.
Looking at his retreating back, Xu Ji couldn't help but sigh in his heart, what a magical young man.
"What's wrong? Lao Xu, are you still reluctant to let me go?"
At this time, Principal Li came over and asked with a smile.
"That's not true. I just feel a little emotional about this young man. I don't know where he can go in the future."
Xu Ji shook his head.
"Let's just watch."
"That's true."
…
Lin Xiao stayed in Shangjing for a few more days, and then returned home. As for Mimi, she was still placed in Professor Zheng's home for foster care.
I was embarrassed to have Professor Zheng’s family help raise her before, but in the past three months, he has tutored Zheng Ronger in mathematics, so that Zheng Ronger has now become the first in her class in mathematics, and even developed her knowledge of mathematics.
Interest can be considered a reward.
Of course, the relationship itself is good, so there is not so much fussing over things, as long as there is a tacit understanding between each other.
After saying goodbye to Professor Zheng's house, Lin Xiao started on her way home.
After spending a year at home, until the end of February 2020, Lin Xiao was ready to leave.
"If you go to France, please be careful."
Yang Rong held the hand of her child who was about to go to a foreign country and expressed concern.
"Don't worry, I won't mess around there." Lin Xiao said with a smile.
"When you go there, you have to listen to the teacher and remember the customs in France, you know?" Lin Guowen next to him also warned.
But before Lin Xiao could say anything, Yang Rong said: "You don't have an accurate understanding of your son's current strength. Maybe after Xiaoxiao goes there, the teachers there will have to listen to Xiaoxiao.
"
As a math teacher, Yang Rong certainly knows how powerful it is to prove Goldbach's conjecture. Mathematicians all over the world have not proven it, but his son has proved it. His son must be better than most mathematics teachers.
Awesome, right?
Hearing what his mother said, Lin Xiao couldn't laugh or cry, and said: "Mom, it's not that bad, I must listen to the teacher's words."
"I know, doesn't this mean you are great? You should respect your teachers and respect your teachings."
"Well, you can rest assured."
Lin Xiao nodded, then looked at the time again, and said quickly: "I have to go, otherwise I won't be able to catch up with the train."
After saying that, he ran away quickly.
"You brat, remember to come back next year! Don't leave me there and never come back!" Lin Guowen shouted.
“I will definitely come back during the Chinese New Year!”
“It would be even better if I could bring a foreign girlfriend back!”
"..."
Lin Xiao didn't reply a word and disappeared directly into the stairwell.
"This stinky boy." Lin Guowen shook his head and cursed with a smile.
Yang Rong patted him and said, "What's so good about a foreign girlfriend?"
"What's wrong with that? How will it save face if you tell me?"
"Do you regret not finding someone from abroad?"
"……How can it be?!"
…
After Lin Xiao returned to Shangjing, he went to Shangjing University to complete his report. A few days later, he embarked on his way to Paris.
Because she had to take Mimi with her, Lin Xiao finally arrived at Paris Charles de Gaulle Airport after two transfers.
Lin Xiao quickly found the place where the pet was checked in. After seeing the airline bag containing Mimi, Lin Xiao quickly rushed up and took a look at Mimi's condition.
Mimi meowed and looked energetic, so Lin Xiao felt relieved.
"Okay Mimi, we won't fly anymore from now on."
After putting the airline bag on his back and zipping up his suitcase, Lin Xiao left the airport and headed to the place where he would stay for the next few years, the Ecole Normale Supérieure in Paris.
