On the afternoon of May 25, Stockholm Airport.

A bright silver flight slowly landed on the runway.

Soon after, Lu Zhou, dragging his suitcase, walked out of the airport through the crowd of people coming and going.

This is his first time in this city, and the most intuitive feeling of this place, in addition to the cleanliness, is the strong artistic atmosphere.

In fact, Lu Zhou does not know much about art, and his rational thinking makes him rarely look at these issues from a perceptual perspective. But even so, he can intuitively feel the strong artistic atmosphere from the city's subway stations.

Because it's no exaggeration to say that it's like a museum.

The 108-kilometre-long metro network houses more than 100 artists who have created artworks dedicated to these metro stations.

It's no wonder that before coming to Stockholm, Edward Witten recommended to him that he should not take a taxi if he could take the metro, otherwise it would be convenient but much less fun.

According to the specifications of the Nobel Prize, the laureate's collapsed accommodation was arranged at the Stockholm Grand Hotel.

At the door of the hotel, Staffan Nomark, permanent secretary of the Royal Swedish Academy of Sciences, Academician Normark, smiled at Lu Zhou and opened his arms and gave him a big hug.

"Welcome, Professor Lu Zhou!"

"Hope it didn't keep you waiting."

"How so?" Academician Staffan smiled and continued, "Allow me to introduce you to this ......"

Standing next to him were scholars from the Royal Swedish Academy of Sciences.

Under the introduction of Academician Staffan, Lu Zhou shook hands with them one by one, and then followed his footsteps to the residence where he stayed.

Standing at the door, Academician Staffan smiled and said politely.

"If you have any needs, please do not hesitate to ask the waiters at the hotel and they will communicate your needs to us."

Lu Zhou smiled and said, "You guys are too polite. ”

"It's not politeness, it's the respect that a scholar deserves," Academician Staffan smiled, "To be honest, I was surprised when I saw you. I originally thought that Tao Zhexuan was young enough, but I didn't expect that in less than four years, another young mathematician broke this record. ”

Tao Zhexuan won the Craford Prize in 12 years, when he was in his thirties, and it was in the same year that he made a breakthrough in the "weak Goldbach conjecture problem", which indirectly led to Hellgot's proof of the problem.

Now in 16 years, the same Goldbach conjecture.

In the dark, it seems that a reincarnation has been formed.

Lu Zhou smiled and said modestly: "Mathematics is an ancient and dynamic discipline, it will get older and older, but the people who study it will get younger and younger. Maybe in the future, someone younger than me will break this record. ”

Academician Staffan smiled and said, "I'm afraid that's a bit difficult." ”

Without bothering him too much, and after informing him of a few things that needed attention, Academician Staffan took his leave.

Putting the suitcase next to the bedside table, Lu Zhou didn't immediately go out for a stroll.

Although he was interested in the city, he had just crossed the Atlantic and half of Europe, and what he needed more was rest.

After going to the bathroom to take a shower, Lu Zhou was lying on the bed and was about to sleep.

At this moment, he suddenly remembered that he had not shared this joy with others, so he sat up from the bed, picked up the mobile phone resting on the bedside table, took a photo of the night scene outside the window, and sent it to the circle of friends and the scarf.

This time, he didn't say a word, just simply posted the photo.

But soon, several replies popped up under his Weibo.

[Lu Shen, this is going on a trip? 】

[Where is this night view?] Hang the big man down. 】

[I guess it's Philadelphia, which is pretty close to Princeton.] After all, the houses here are too low, not like New York. 】

[I'm about to take the college entrance examination, touch Lu Shen's thigh at close range, and take a breath of European air by the way! ] 】

[It's a long life! Lu Shen didn't pretend to be forced!! 】

Seeing the comments under the scarf, Lu Zhou couldn't help but smile embarrassedly.

How to speak!

Am I that kind of person?

……

The next afternoon.

The quaint Stockholm Concert Hall, filled with melodic and elegant classical music, is packed with more than 1,000 seats.

After a brief opening remarks, a middle-aged woman with short hair and smart hair stepped forward to announce the start of the award ceremony.

Her name is Barbara Cannon. Cannon), who is the president of the Royal Swedish Academy of Sciences. Although most of her face is covered by the crow's feet of the years, it can be seen that when this lady was young, she must have been a scholar with both appearance and knowledge.

In solemn and warm applause, Academician Staffan Nomark, the permanent secretary of the Royal Swedish Academy of Sciences, took her place, stepped up to the stage, and read out the list of winners and the award speech.

“…… The future of mankind lies in the infinite starry sky, and one day, we will reach all the places we see. Let us thank the pioneers who looked up to the stars, and let us send blessings and applause to them! Thank you for your outstanding contribution to the study of black holes by angular momentum and their effects! ”

"The winners of the Astronomy Prize are Professor Roy Kerr from the University of Canterberry in New Zealand, and Professor Roger Branford from Stanford University in the United States!"

Academician Staffan's subdued voice ignited the atmosphere in the venue.

Under a round of applause, two professors from New Zealand and the United States stepped onto the podium and solemnly received the medal from Gustav XVI.

Lu Zhou, who was standing under the stage, took a deep breath and gently adjusted the tie on his chest.

Originally, he thought he would be calm, but in the last few seconds, he still had to try to control his breathing and heartbeat.

Different from the Chern-Chern Prize in Mathematics issued by the Chinese Mathematical Society and the Cole Prize issued by the Federal Mathematical Society, this honor is not only recognized by the mathematical community, but also recognized by the entire natural science community.

Academician Staffan on the stage, continued.

“…… Mathematics is the language of God, and prime numbers are the password that He left in the mortal world. Many propositions are not necessarily great in themselves, but it is precisely because of these ordinary but not simple, complex but pure things that our world and our civilization are quietly changing. ”

"Thank you for his outstanding contributions to a range of studies on prime number problems! And, proof of Goldbach's conjecture! ”

"The winner of the Mathematics Prize is ......"

"Professor Lu Zhou from Princeton University!"

The audience erupted in louder applause than before.

Like the undulating waves of the sea, it endures.

In the applause, Lu Zhou walked smoothly onto the podium.

In the decades since the establishment of the Cafford Prize, this is the first time that a Chinese scholar has stood here.

More than 200 scholars of different colors and nationalities, as well as nearly 1,000 invited guests from various fields and identities, offered blessings and applause for his contributions to the world.

And at this moment, standing in front of him were Gustav XVI and his queen Lady Sylvia.

"Congratulations, Professor Lu Zhou!"

With a smile like a spring breeze on his face, the white-haired old man solemnly handed the medal and certificate in his hand to Lu Zhou.

After taking both hands, Lu Zhou shook hands with the king, nodded and smiled: "Thank you!" ”

Applause rang out again.

It wasn't until the laureate from China stood aside with a smile that Academician Staffan stepped forward again that he slowly calmed down.

However, for Lu Zhou, the ups and downs in his chest did not simply calm down like the applause that gradually subsided.

Feel the weight of this medal, until the elegant classical music sounds, until the award ceremony comes to an end, until the guests in the venue begin to leave their seats......

Lu Zhou's mood returned to calm.
