My house collapsed since I became the top scorer in the college entrance examination

Chapter 100 Professor Eleonora Walls
As the plane landed slowly, Xiao Ran looked out the window and the Philadelphia airport gradually became clearer, and a hint of joy appeared on his face.

"finally reached!"

Kong Jiyuan, who was sitting next to Xiao Ran, also breathed a sigh of relief.

No matter how many times he has flown, he is always a little worried when he doesn't land safely. After all, news about plane crashes is not uncommon these days.

Seeing that the plane landed safely, he was relieved. Then he smiled and patted Xiao Ran's thigh, reminding: "Xiao Ran, you can prepare to pack your luggage. Remember, you must follow me closely when you leave the cabin. Mr. Wada and others, try not to leave the team and act alone."

"After all, foreign countries are not as good as domestic ones. We are not familiar with the place and the public security is a little worse. If you can follow the acquaintances, follow them as much as possible. In addition, pay attention to your luggage. It is best to keep your wallet and mobile phone close to you. The airport is crowded and there are many thieves and pickpockets. few."

"I understand, Senior Kong." Xiao Ran smiled helplessly. He had already noticed Kong Jiyuan's verbosity on the plane, and now he was no longer surprised.

Kong Jiyuan may have noticed Xiao Ran's helplessness, and immediately touched the back of his head angrily, showing an embarrassed smile: "No matter what, it's better to be careful when going out."

Five minutes later, the plane door opened, and Xiao Ran followed the team led by Director Tian to get off the plane.

After walking out of the cabin, the airport hall was bustling with people and noisy sounds filled the hall. Xiao Ran looked around and found that many people were holding various signs in their hands and watching their flight happily.

"Director Tian, ​​I see Mr. Zhao." A graduate student in the team excitedly pointed to a hand held not far away [Warmly welcome the delegation from the School of Science and Technology at Yanda! 】 sign, he reminded Director Tian.

"Let's go there, Zhao Licheng must be waiting impatiently." An old professor from the School of Mathematics said cheerfully.

"This kid." Director Tian smiled and shook his head, "I told you so many times when I came here that you don't have to come to pick us up, but you just don't listen. You're so stubborn!"

As he spoke, he walked towards that direction.

Kong Jiyuan led Xiao Ran to follow him, and introduced Xiao Ran as he walked: "The man in the distance who is holding a sign to welcome us is named Senior Zhao Licheng. He was also a famous figure in Yanda, and he is an outstanding person. Now he is an assistant at Princeton University. professor."

After meeting up with senior Zhao Licheng who was picking them up at the airport, everyone chatted for a while in the airport lobby.

Kong Jiyuan also introduced Xiao Ran to several senior students who were with them. Xiao Ran said hello to them one by one, and they seemed to be familiar with them.

After more than an hour's drive, Xiao Ran and others finally arrived in Princeton.

The International Mathematical Union was held at Princeton University, and the hotel arranged by Senior Zhao Licheng for them was the Nassau Inn Hotel, which is the closest to Princeton University.

After taking Xiao Ran and others to check in at the counter, the hotel waiter took everyone to their respective rooms.

Xiao Ran's room number is 408, and Kong Jiyuan lives next door to him.

The first thing Xiao Ran did when he dragged his luggage into the hotel room was to go to the bathroom and take a hot shower. After flying for such a long time, his body was already exhausted. After taking a shower, he relaxed his body and immediately lay down on the bed. Just sleep and get rid of the jet lag.

Three or four hours later, Xiao Ran's door suddenly rang. When he opened the door, standing outside the door was senior Kong Jiyuan.

Kong Jiyuan smiled and asked: "Xiao Ran, how are you feeling? Have you adjusted to the jet lag?"

Xiao Ran nodded: "It's not bad. I feel much more energetic after a good sleep."

"That's good. There's a party happening in the hall below. Many of the people attending the party are international math experts. Do you want to go see something and make some new friends by the way?"

"Well, senior, wait for me. I'll wash up and come down right away."

"no problem!"

In the hotel lobby, Kong Jiyuan took Xiao Ran down from the elevator, grabbed a glass of champagne from the waiter's tray, and while walking towards the lobby, he introduced to him in a casual tone what he needed to pay attention to during the party.

"Haha, Xiao Ran, Ji Yuan, you came just in time." Director Tian, ​​who was talking to a few foreigners in the distance, suddenly lit up when he saw Xiao Ran, and quickly waved to Xiao Ran and the two.

"Director Tian, ​​good evening!" Xiao Ran and Tian Jiyuan came over quickly and greeted politely.

"Good evening." Director Tian nodded cheerfully, then looked at Xiao Ran and said enthusiastically: "Xiao Ran, you came just in time. We were talking about you just now. Come on! Let me introduce you to you. This is Ai Professor Leonora Walls, he was the one who reviewed your paper in the Annals of Mathematics. In addition, he is also a good friend of Lao Lu and I."

Following Director Tian's gaze, Xiao Ran looked at the old man with silver hair combed meticulously.

Professor Walls looked at Xiao Ran and his eyes also lit up: "Are you Xiao Ran, the author of "Discussion on the Application of Random Matrix in Multiplication - Taking the Proof of Stirling's Formula as an Example"?"

"If there is no other person named Xiao Ran here, I think I should be the author of the paper you mentioned, Professor Walls." Xiao Ran replied with a smile, neither humble nor overbearing.

"Haha, funny young man." Professor Walls chuckled, and at the same time looked at Xiao Ran carefully, with a flash of surprise at his appearance in his eyes, and praised him: "Xiao, I have to say, your appearance is as good as yours." Just as talented in mathematics!"

This compliment makes people feel very comfortable!
Xiao Ran knew that the thinking of these foreigners was different from the introverted modesty of Chinese people. They preferred to express their individuality and be straightforward, so he was not as modest as usual, but nodded generously and said: "Thank you for the compliment, Professor Walls. Your charm is no less than your achievements in mathematics."

Everyone carries the sedan chair, and the communication between people is, to put it bluntly, nothing more than that.

Professor Walls, an old boy, was so flattered by Xiao Ran's flattery. Although Professor Walls is now a veteran, judging from his facial features, he was also a handsome guy when he was young. He is probably quite handsome. Popular with girls.

Xiao Ran's polite flattery obviously touched his heart, and he was immediately "longyan delighted" and looked at Xiao Ran with much more eager eyes.

Director Tian smiled dumbly as he watched the two complimenting each other's looks, and changed the subject: "Xiao Ran, where will your academic report be scheduled? Have you finished the PPT for the speech? Do you need me to help you organize it? "

"The academic report will be held on the morning of the third day, in Lecture Hall 3." Xiao Ran answered honestly, paused, and continued: "As for the PPT, we have already finished it, and we don't need Director Tian's help for the time being."

"What academic report?" At this time, Kong Jiyuan on the side had not yet turned his head and asked subconsciously, feeling a little confused.

Director Tian glanced at him and replied casually: "Just think that Xiao Ran is just like you and is just here to be an audience. I have a 30-minute academic report waiting for him."

! ! ! !
Xiao Ran? A 30-minute academic report? ? ! !

Kong Jiyuan was stunned for a moment. He kept a dull expression and turned his head little by little to look at Xiao Ran. He swallowed and stammered, "Junior Xiao Ran, you. Why didn't you tell me about this?" Xiao Ran spread his hands and said in a helpless tone: "You didn't even ask. I can't take the initiative to tell you that I have a 30-minute academic report waiting for me. The element of showing off is too obvious. I I’m afraid you won’t be able to accept it anymore.”

There seems to be nothing wrong with this!

But Kong Jiyuan was still a little messy. He opened his mouth but didn't know what to say. In the end, he could only sigh with a complicated expression.

As the proud son of heaven since childhood, he felt the differences between people for the first time in his life, and this frustrating feeling was actually brought to him by a freshman.

Nima is outrageous!
"Tian, ​​I think you are wrong. Xiao's academic report is not 30 minutes long, but 45 minutes." At this time, Professor Walls interrupted with a smile.

"what??"

Director Tian was also stunned for a moment. His brain only thought for a moment, and he instantly realized that the sudden increase in the length of Xiao Ran's academic report must be related to the topic of the paper he submitted to the committee.

It seemed that Xiao Ran's academic report this time was obviously approved by the committee, otherwise the meeting time would not have been specially increased for him.

Thinking of this, Director Tian nodded thoughtfully and asked, "Xiao Ran, what is the theme of your academic report this time?"

"Kratz! Approximate proof of Kratz's conjecture!" Before Xiao Ran could answer, Professor Walls answered first with a smile on his face.

"I have to say that Xiao's talent in mathematics is really amazing. I thought Xiao's talent was only in random matrices, but I didn't expect that his academic report paper gave us a surprise this time."

Speaking of this, Professor Walls still couldn't hide his excitement, and even praised Xiao Ran unstintingly: "Although he has not completely proved Kratz's conjecture, he used differential partial differential equations to prove that Kratz's conjecture is still To our considerable enlightenment, he found a way to further this process.

To be honest, when I first saw this paper, I was very excited and thought it was very compelling.

Using this technique, Xiao demonstrated that almost all initial Collatz values, 99% or more, end up at a value very close to 1, allowing him to derive 99% of initial Collatz values ​​greater than 1 quadrillion Sequence, conclusion that the final result is less than 200.

It can be said that this is the strongest proof result in the history of this conjecture. "

"An approximate proof of Kratz's conjecture." Director Tian was stunned for a few seconds. He came back to his senses. He looked at Xiao Ran as if he were looking at some precious animal and said with a strange look on his face: "Why did you suddenly think of studying Kratz's conjecture? ? And there’s also a breakthrough?”

As he spoke, he couldn't help but look at Xiao Ran in surprise: "Did you just think of it on the spur of the moment or had it been planned for a long time, but you just decided to come up with it when you happened to meet the International Mathematical Union this time?"

Xiao Ran said with a smile: "It can only be said that it's just the right time. Kratz guessed that I have been researching it since the end of the college entrance examination, and only recently did I make some progress."

To be precise, it is not a breakthrough, but the proof of Kratz's conjecture has been completed.

However, he was concerned that if he rashly wrote out all the methods to prove the Kratz conjecture and sent it to the committee, it might cause unnecessary trouble.

After much thought, I decided to first come up with an approximate proof of the Kratz conjecture as the topic of an academic report, and then prove the Kratz conjecture in the academic report in front of everyone.

This is the safest way to do it.

Although the academic circle is relatively pure compared to other industries, it is not without all kinds of dirty things. These days, whether at home or abroad, things like paper fraud, plagiarism, substitution, and taking advantage of students' achievements are not uncommon. .

If the boss of the International Joint Committee on Mathematics suddenly took a fancy to his method of proving Kratz's conjecture and took advantage of it to publish it first, wouldn't that be just disgusting?

Although the chance of this happening is small, it is not impossible.

Whether he is being cautious or judging a gentleman's heart with a villain's heart, no matter what, it is necessary to be on guard against others, so it is necessary to hide something appropriately.

When Director Tian heard Xiao Ran say that he had been studying since the college entrance examination, he was instantly relieved.

Let's just say that it had only been a month since he notified Xiao Ran to give an academic report. If he could study Kratz's conjecture to this extent in just one month, that would be an exaggeration!

But then he thought that even if he started researching from the college entrance examination, it has only been three or four months, which is also an exaggeration!

"What a little monster!" Director Tian couldn't help but muttered in a low voice.

He chatted with Director Tian, ​​Professor Walls and others for a while, chatting about the Kratz conjecture, until more and more people joined the chat.

At this time, it was his turn to listen to the experiences of the big guys who came to the party.

It has to be said that for Xiao Ran, such experience is also very scarce. Maybe it was just a flash of idea from a certain boss, which benefited Xiao Ran a lot.

The party lasted until about nine o'clock, and Xiao Ran returned to his room.

I took a cold shower first to sober up. I drank a lot of champagne at the party, but I didn't eat much. I only ate some desserts to fill my stomach.

Now he was too lazy to go out for supper. After taking a shower, he changed into thinner and clean clothes.

Then he took out the "Fundamentals of Number Theory", "Topology" and "Differential Geometry" from the box one by one and put them on the table and put them neatly.

Then, I turned on the desk lamp, sat at the desk by the window, and casually opened a copy of "Differential Geometry" and started reading.

It has been more than a year since I came to this world.

At first, it was just to create the persona of a top student, but after a while, I gradually got used to this kind of life.

Be self-disciplined and sufficient, and don’t get caught up in confusion about the future and longing for the society in your previous life.

Unconsciously, three or four hours passed by in a flash, and Princeton was already shrouded in boundless silence and darkness.

Turn off the lights and go to sleep, have a good night's dream.
