Xu Xingguo turned his gaze to Pang Xuelin and said, "Professor Pang, congratulations, as long as you complete the next dissertation defense, you will receive a doctorate degree in materials science and engineering awarded by this university!" ”

Pang Xuelin said with a smile: "Thank you!" Professor Xu, Professor Li, Professor Tao, Professor Chu, Professor Changqing, you have worked hard today. ”

"No hard work, no hard work!"

"What an eye-opener for us today!"

"Haha, Professor Pang, I hope that we will have the opportunity to cooperate in the field of materials science in the future......"

……

Xu Xingguo said: "Professor Pang, since the assessment has been passed, and the project team on Lao Li's side is almost ready, let's officially enter the experimental process." ”

Pang Xuelin said: "Okay, Professor Changqing, let's do it, tomorrow I will take a day to talk to the project team members about some details and points of this experiment, because I will focus on the report meeting next, so I'm afraid I won't have much time to take care of the laboratory, and I will trouble you a lot next!" ”

Li Changqing said with a smile: "Professor Pang, where is this troublesome, your experimental plan has clearly analyzed the whole process, we can just do it, if there is a problem at that time, then I will come to you again!" ”

Pang Xuelin smiled: "It's okay, I'm bothering everyone today, it's almost time now, so let's invite everyone to dinner......"

Xu Xingguo said with a smile: "Okay, our rich man just won a bonus of 1.5 million US dollars, and today he is just fighting the local tyrants to divide the land!" ”

The crowd burst into laughter.

For Pang Xuelin's invitation to dinner, of course they will not refuse, and building a good relationship with such a top scholar who is destined to have a promising future will only benefit their future development, not harm.

The next day, Pang Xuelin went to Li Changqing's laboratory again, met with the project team members, and explained the key points of the experiment.

The project team has a total of four people, an associate professor, plus three doctoral experimental dogs, although Pang Xuelin is not a material science major, but these people see Pang Xuelin, and their performance is not much worse than the appearance of fans when they see idol stars.

As for whether this experiment can be restored, Pang Xuelin is not worried at all.

The preparation of high-purity carbon nanotubes has long become a classic materials science experiment in the wandering earth world, and various key points and difficulties have been summarized clearly by materials science experts all over the world.

After Pang Xuelin's explanation is completed, as long as he continues to do it step by step, he will definitely be able to produce results.

Next, Li Changqing's laboratory officially began the preparation and characterization experiments of high-purity carbon nanotubes.

Pang Xuelin also devoted all his energy to the writing of his thesis and the preparation of the Ponzi Geometry Symposium.

Time passed day by day, and soon it was time for the briefing.

On December 20, the day before the official opening of the report meeting, the magic capital Pudong International Airport.

Shinichi Mochizuki carried a large box of luggage and walked out of the international passenger passage with the flow of people.

As soon as I looked up, I saw a pick-up sign, which was written in Chinese and English: Jiangcheng University Ponzi Geometry Report Attendees Pick-up Report Office.

Shinichi Mochizuki walked over with his invitation and saw two old acquaintances, Peter Schultz and Jacob Sticks.

The three of them looked at each other, and Shinichi Mochizuki couldn't help but feel a little embarrassed.

Last year, he also quarreled with Schultz and Stitches over the generalization of the Teishmüller theory and the proof of the ABC conjecture.

The two sides also issued a document to refute each other.

As a result, a year passed, and finally Pang Xuelin gave the answer.

Shinichi Mochizuki was wrong, but not the one Schultz and Stitches were referring to.

Schultz seemed to see Shinichi Mochizuki's embarrassment, and said, "Mr. Shinichi, you are here too." ”

Mochizuki nodded, first reported to the staff of Jiang University who was in charge of picking up the airport at the scene, and then came to Schultz and Stitches, and said, "When did you arrive?" ”

Schultz said: "We arrived for a while, and the teacher from Jiang University said that the bus to pick up the airport was in the parking lot, and we would leave for Jiang University when we were almost there." ”

At this time, Sticks said, "Mochizuki, have you heard?" This time, Perelman will also be over. ”

Mochizuki Shinichi was slightly stunned, and wondered: "That guy is finally willing to go out?" I've emailed him a few times to talk to him, but he doesn't want to come to Japan. ”

Schultz smiled.

Shinichi Mochizuki doesn't seem to be far behind, and he was willing to meet with the two of them when he and Stickers came to the door last year.

Compared to these two well-known otaku in mathematics, Schultz has a much more lively personality and likes to travel around.

After graduating with a Ph.D. that year, he spent half a year traveling to top universities and research institutes around the world.

The three of them chatted with each other, and slowly, more and more people reported it.

Seeing Shinichi Mochizuki standing with Schultz and Stickers getting along well, many mathematicians who recognized their identities showed strange expressions on their faces.

Last year, these three people were still in a big fuss in the mathematics community, and this year they are drinking and talking?

At this moment, I don't know who shouted: "Look, that person is not Perelman!" ”

As soon as Mochizuki Shinza looked up, he saw a bearded Slav with a backpack on his back, dressed scruffily, tall, and looking a little confused, walking out of the international passenger passage.

The bearded man looked around and finally saw the signboard of Jiang Da to pick up the plane.

He walked up to sign in first, then looked around at the mathematicians waiting on the side, and walked straight to where Shinichi Mochizuki was.

"Mochizuki, long time no see!"

"Mr. Perelman, I didn't expect you to come too!"

Perelman's English has a strong Russian accent, and Shinichi Mochizuki's Japanese accent is also strong, but there is no barrier to communication between the two.

Perelman said: "The Ponzi geometry that Pang made is very interesting, I studied it for more than a month, and found that this new branch of mathematics is inextricably linked to many fields, so I wanted to take this opportunity to come and talk to Pang." Mochizuki, you are an expert in the direction of far-abelian geometry, you should have a deeper understanding of Ponzi geometry, right? ”

Mochizuki nodded and said, "This is also the reason why I went to Jiang University this time, I plan to study at Jiang University for a while. ”

Schultz on the side couldn't help but be taken aback: "Mr. Mochizuki, are you really going to stay at Jiang University?" ”

Mochizuki nodded and said: "I don't think the mathematical community has really realized the importance of Ponzi geometry until now, this new theory is not just as simple as helping to prove a few conjectures, I vaguely feel that its birth will change the discipline of mathematics." ”

Schultz and the others couldn't help but be taken aback.

Although they have a high opinion of Ponzi geometry, it is not as high as Shinichi Mochizuki.

At this time, Perelman turned his gaze to Schultz and said, "Who is this ......?" ”

"Peter Schultz! The man next to me is Jacob Stitch, a professor at the Goethe University. ”

Perelman said: "Hello, Schultz, I know you, the 2018 Fields Medal winner, you put forward a very good theory of space that seems to be complete......
