Back at the hotel, it was already ten o'clock in the evening.

Pang Xuelin passed by the door of Qi Xin's room, hesitated for a moment, and did not knock on the door, but sent her a WeChat message: "I'm back." ”

Until before going to bed, Qi Xin did not reply.

Pang Xuelin didn't continue to send it to her.

However, Yao Bingxia used WeChat to chat with Pang Xuelin from time to time, and after breaking the film between each other, Yao Bingxia seemed to have endless topics, completely looking like a little girl in love.

It wasn't until the next morning that Pang Xuelin saw Qi Xin again.

Qi Xinhe didn't seem to be abnormal, and he also shouted as a junior, but there was no longer the closeness between his eyebrows.

Pang Xuelin was a little uncomfortable, but he didn't know what to say.

At breakfast, Pang Xuelin met Yun Zhihui and Zhang Wei, who were also attending the meeting, and before Pang Xuelin became famous, these two were the most prestigious figures of the younger generation in the Chinese mathematics community.

Zhang Wei is the winner of the last Morningside Mathematics Gold Award, and Yun Zhihui is the winner of the Ramanujan Prize at the Samha Institute of Humanities and Science and Technology in India.

In 2017, they were awarded the New Horizons in Mathematics Prize for their discovery of the higher-order Gan-Gross-Prasad conjecture in the field of functions.

When Pang Xuelin was studying in graduate school in the United States, he once followed Tao Zhexuan to participate in some academic conferences and met with them, so they were not strangers to each other.

"Professor Pang, this ICCM Mathematics Gold Medal, it should be that you didn't run away, and I also heard that this year, the Mathematics Gold Medal may only be awarded to you alone."

Zhang Wei said.

Pang Xuelin was slightly stunned, and said suspiciously: "Isn't the gold award generally awarded to two people?" ”

Yun Zhihui smiled bitterly: "Who called your results so amazing, BSD conjecture, ABC conjecture, Ponzi geometry, partial differential equations...... Any one of these achievements can reach the top, and you alone hold four, and now who dares to be tied with you. ”

Originally, according to the normal situation, Yun Zhihui could compete for this year's ICCM Mathematics Gold Medal.

But with the existence of Pang Xuelin, who is qualified to be compared with Pang Xuelin.

It's all about looking for spray.

Yun Zhihui can either win a silver award for comfort, or he can only wait for the next ICCM to compete.

Pang Xuelin smiled, and didn't know how to comfort the other party for a while.

At this time, Qi Xin, who was sitting next to Pang Xuelin, looked at his watch and said, "Professor Pang, it's almost time, it's time for us to go." ”

Pang Xuelin and Qi Xin got up one after another, followed Yun Zhihui and Zhang Wei out of the hotel lobby, crossed the road, and directly entered the opposite Tsinghua Garden.

Under the guidance of the volunteers, they soon came to the main venue of the ICCM conference, the Tsinghua Auditorium.

At the entrance of the auditorium, Guo Kangcheng, vice president of Tsinghua University, whom he had met yesterday, was receiving guests from all over the world.

Pang Xuelin and the others went up to chat with Guo Kangcheng, and then directly entered the auditorium hall.

There were already a lot of people in the auditorium, and when they saw Pang Xuelin coming in, whether they knew each other or not, they would come forward to say hello to Pang Xuelin.

After all, whether in terms of coffee position or academic achievements, Pang Xuelin is the biggest academic star of this mathematician conference, and Yau Chengtong can be compared with him with his qualifications and prestige.

Pang Xuelin asked Qi Xin to find a place to sit down in the audience, and he walked to the stage in front of the auditorium under the guidance of the on-site staff.

There are more than a dozen chairs on the stage, all of which are from all over the world attending the World Conference of Chinese Mathematicians.

For example, Jane Pierre Bougnon, academician of the European Academy of Sciences and president of the European Research Council, Motoko Kotani, director of the Institute for Advanced Study of Molecular and Atomic Materials Science at Tohoku University in Japan, winner of the Wolf Prize, Rolf Schock Prize, Heinz Hopf Prize, and professor at the University of California, Irvine, Richard Shawn and others.

Behind the chair, there is a three-stage giant screen projection with the icons of the World Conference of Chinese Mathematicians|Award Ceremony and Forum and this year's ICCM Conference.

Pang Xuelin's seat is actually in the middle, his left side is Yau Chengtong, on the right is the president of Tsinghua University, and other top scholars from home and abroad are on the left and right, which can be described as the stars holding the moon.

At 9 o'clock in the morning, in the opening speech of the host, the 8th World Congress of Chinese Mathematicians was officially opened.

First of all, Yau Chengtong and the president of Tsinghua University, as the organizer, took the stage to give speeches one after another.

At ten o'clock, the award ceremony officially began.

"Last year's mathematics community was an unquiet year, but also the most exciting year since the 21st century, BSD conjecture, ABC conjecture and other major problems that have plagued the international mathematical community for many years have been solved one after another, a young genius scholar, in the process of blooming bright light, his name, resounding throughout the international mathematical community."

"Therefore, it is ...... who won this year's ICCM Gold Medal in Mathematics"

The host may have wanted to leave a suspense and deliberately paused.

As a result, the audience in the audience actually shouted: "Pang Xuelin! ”

Immediately after, there was a burst of laughter at the scene.

Qiu Chengtong, who was sitting next to Pang Xuelin, said with a smile: "Professor Pang, it seems that you can't accept this award if you don't accept it." ”

Sure enough, the host laughed and said: "Okay, since everyone has already snatched my lines, then I won't read it, next, we have asked Academician Yau Chengtong to present the award to Professor Pang Xuelin!" ”

Soon, thunderous applause resounded throughout the audience.

"Professor Pang, please!"

Pang Xuelin and Yau Chengtong got up one after another and came to the podium, Yau Chengtong picked up the medal certificate from the staff, handed it to Pang Xuelin's hand, and said with a smile: "Professor Pang, the development of Chinese mathematics in the future will be a lot for you!" ”

Pang Xuelin nodded, and said with a straight face: "Definitely!" ”

The prize of 25,000 US dollars is not much, but this award represents the recognition of Pang Xuelin by the Chinese mathematical community.

Then, Pang Xuelin came to the podium and said with a smile: "Thank you." ”

"It is a personal honour to receive the ICCM Mathematics Award and I am glad that my work has been recognized by everyone. Today, I would like to take this opportunity to talk to young scholars who are interested in entering the field of mathematics. ”

"As a discipline that has existed since the birth of human civilization, mathematics is the most resource-saving discipline and tools, but it is also the most demanding subject of talent and perseverance. Computers can help some branches of mathematics with calculations, and they can also help mathematicians think with some wonderful images, but they can't help most pure mathematicians. ”

"I asked myself that my aptitude is very average, and a friend joked that my IQ was 180, but if I measured it accurately, I don't think it would exceed 120, in other words, just an ordinary normal person. If you choose mathematics just to find a job where you can make a living, you will most likely regret it in the near future, there is no golden house in mathematics books, and there is no Yan Ruyu. Nowadays, many students choose mathematics majors with a bit of blindness, and they can't say that they understand it, let alone like it, so they come in in a daze. As everyone knows, decades of almost ascetic-like life are not something that ordinary people can persevere. ”

"I am fortunate to receive such an honor and recognition at this age, but I do not want to be a role model for many young scholars. Of course, if you are really interested in mathematics, can immerse yourself in mathematical research, and can enjoy the feeling of arranging troops and strategizing in the process of mathematical research, then I welcome you to join in. What the math community needs is a genuine love for mathematics and a new source of fresh blood for it, not just as a tool to make a living. ”

"Thank you, and once again thank Academician Yau Chengtong and the Organizing Committee of the World Congress of Chinese Mathematicians."

Pang Xuelin bowed to the audience, and then returned to his place.

Soon, the applause rang out again, and it didn't go down for a long time.

Yau Chengtong whispered to Pang Xuelin, who returned to his position: "Professor Pang, you said well in your acceptance speech, during this time, the atmosphere in the domestic mathematics community is indeed a little impetuous, and you need to pour cold water." ”

Pang Xuelin smiled: "I just felt it, and I didn't think too much about it." ”

Yau Chengtong smiled and asked again, "By the way, Professor Pang, did you only prepare one copy of your acceptance speech?" ”

"Huh?"

Pang Xuelin looked at Qiu Chengtong with some confusion.

Yau Chengtong smiled mysteriously and said, "You can continue to watch." ”

At this time, the moderator came to the stage again and said: "Thank you very much Professor Pang for your speech, I think most of the scholars here can relate to what Professor Pang said. We also hope that in the future, there will be more scholars who truly love mathematics to enter our industry. ”

"Next, we will announce the second award of this year's World Congress of Chinese Mathematicians, that is, the ICCM Gold Medal in Applied Mathematics, and its winner is ......"

The host opened the envelope with the name of the winner written on it and couldn't help but be stunned.

When the audience saw that the host was suddenly stuck, they couldn't help but sound a buzzing sound.

Soon, the host reacted and said: "Its winner is Professor Pang Xuelin!" ”

When the words fell, not only Pang Xuelin was stunned, but the entire auditorium hall was also instantly silent.

Immediately afterward, the Tsinghua Auditorium boiled like a hot oil pot poured with water.

The ICCM Gold Medal in Mathematics and the ICCM Gold Medal in Applied Mathematics represent the highest awards of the ICCM Congress.

The Gold Medal in Mathematics generally refers to a breakthrough in the field of pure mathematics, while the Gold Medal in Applied Mathematics is generally very closely integrated with other disciplines.

No one expected that the ICCM Organizing Committee would award these two awards to the same person.

This is an unprecedented precedent in history, and even in the future, it is difficult to say whether anyone can win the double prize in mathematics and applied mathematics at the same time like Pang Xuelin.
