"...to Langton?? Cray and his wife, Ravinia Cray, to the Cray family, to the members of the Riemann family, to all the mathematicians who came to this historic occasion."

“At the meeting held in Paris twenty-three years ago, the Clay Institute of Mathematics announced the awards for the seven most famous problems in the world. Although we don’t need those, it does not make real mathematics. The family is more excited about math performance."

"But that doesn't mean it's not important."

“On the contrary, it records the unresolved greatness of the twentieth century for our descendants. Its role has also made the non-mathematical world more enthusiastic about mathematics. As a special, it has always been a beacon. Responsibilities attract young people, children and students to be interested in evolving math and math-related issues."

"Whether it is really love, or for that one million bonus."

French Academy.

The spacious auditorium is a bit crowded.

Because it was the award ceremony of Riemann's conjecture, almost the top scholars in the French mathematics field, as well as members of major mathematics organizations, were invited to stand here.

Before the millennium, it was once the center of mathematics in Europe and the world. It was the dream of countless mathematicians to be able to speak here.

Even today, this glory has long since faded because of the overall decline of the European mathematics community, and many things have not changed.

Standing on the podium, facing the solemn meeting, Professor Carlson paused for a while and continued in a solemn tone.

"Nils Henrik Abel once wrote in his memoirs that in order to solve a difficult problem, it must first be correctly expressed..."

"...especially, the correct formulation."

“What we can see is often not as straightforward as we think it is, just like the theorems we know well. Every theorem is surrounded by centuries of hard work and effort, and the efforts of countless generations of scholars. Our discipline is also able to advance in this bit of accumulation."

"On this road full of thorns, we have gained a lot. As Professor Lu Zhou reveals to us, we know the mystery of the zero distribution of the Riemann function and the profound mathematical meaning behind it - 'geometry and algebra Unity'. The birth of this theory reconstituted algebraic geometry after the millennium, and even redefine our understanding of numbers and geometric figures."

“Maybe, we may need to spend decades or even more to build a new building on the land that he opened up. But the first step to the new world, we have already taken it, I believe there will always be someone We saw that day."

The lengthy awards were finally finished.

The old Professor Carlson was slightly embarrassed, and thunderous applause sounded from the audience.

In the applause, Lu Zhou walked from the side to the front of the stage, took the one million dollar check from Professor Carlson, and showed a smile on the face that met the expectations of the other party, and politely shook him. Handshake.

"Thank you."

It is good to have money.

Although one million bonuses may be less than the 10 billion big projects yesterday, the mosquitoes are small and meaty. Who would think that they have more money?

Finally, this difficult task was completed, and Professor Carlson’s face was relieved.

He feels that there is no such thing as a humble person in the world.

Obviously it is to send money, and it is still a million prizes, and the winners are more difficult than one.

Holding the hand of Lu Zhou tightly, Professor Carlson said excitedly.

“Is there any award-winning speech? Just talk about it.”

Acceptance speech?

After hearing the words of Professor Carlson, Lu Zhou seriously thought about it for a while, and his face showed a sad smile.

"Those feelings... It seems to have been said the last time, just like the last time."

Being drowned in the applause, this sentence seems to be heard only by Professor Carlson.

Seeing his old face that gradually became red because of rising blood pressure, and the expression of wanting to hit someone but smiling, Lu Zhou suddenly had some luck, but fortunately the applause was big enough, but he had not put it to the microphone before. ......

......

In the evening, also in the ballroom of the French Academy, the French Mathematical Society and the Clay Institute of Mathematics jointly organized a dinner. Regardless of whether the day was at the awards ceremony, the banquet was almost missed by all the mathematicians in Paris who had heads and faces.

During the dinner, Lu Zhou met many old friends who had not seen many times.

Especially Professor Helfgott, who is a teacher at the Paris High School.

The Peruvian-born French digital theorist gave him a lot of help when he studied the Goldbach conjecture. In particular, the proof of the weak Goldbach's conjecture gave him a lot of inspiration in the fusion of the mathematical tools of sieve and circle.

Since the settlement of Goldbach's conjecture, Lu Zhou has rarely published articles in the field of number theory, so the two have not communicated for some years. However, although there were fewer meetings, the friendship between the two was still there.

This time, the Professor Helfgott was quite enthusiastic and talked with Lu Zhou for a long time. Lu Zhou also heard from him many things about Professor Grothendieck's life and some rumors about Professor Abel.

"We make a hypothesis."

Helf Gott: "Assumption?"

Refilling himself with a glass of champagne, Lu Zhou said with a chattering voice: "If there are aliens in this universe... Of course, I mean, if the species are completely different and difficult to directly contact, How do we build good communication with them?"

Professor Helfgott squinted a little and looked at Lu Zhou strangely.

"Are you discovering aliens?"

Lu Zhou squatted and then laughed.

“How is it possible? Isn't this a hypothesis? Why do you think I have found it?”

Helfgott said with a smile: "Because every time a problem is thrown out by you, this problem seems to have been solved by you half. You are a person who will not leave the opportunity to others, I said Right?"

Uh?

Have it?

Lu Zhou thought about it carefully, as if it was really the case.

Although in his own opinion, those results are calculated by a lot of effort, but in the eyes of others, those mathematical propositions that were originally based on the annual cycle are difficult to be counted by themselves for months or even a few. It’s done in a week, so it sounds a bit exaggerated.

Looking at Lu Zhou, who was embarrassed and smiling on his face, Helfgot smiled and took a sip of wine. After pondering for a while, he returned to the previous interesting question.

"If you must communicate in the first place of contact... I think it is mathematics."

Lu Zhou raised his eyebrows with interest.

"Oh?"

It’s a coincidence that they thought of a piece.

"The key to the communication between the two civilizations is to find a common language, just like the cup in my hand. If they don't use the cup as a container or drink, then the exchange can't begin," put down the glass in his hand, Helfgott. The professor pondered for a while and continued. "Science is the means to solve the problems we face. The problems we face may be different, but one thing should be the same. That is the tool for studying science."

"Whether it is natural science or applied technology, no matter which one is inseparable from mathematics."

"So I think it should be math."

Lu Zhou: "If you are the alien, now you want to talk to me about what to eat at noon tomorrow, what do you do?"

Helfgott leaned back in the chair and said with a smile.

"I? I will throw you two big primes first... Of course, instead of throwing them directly at you, I will multiply them together. If you can solve them, at least... tomorrow's lunch is not for you."

"It’s very interesting to say," amused by this humorous statement. Lu Zhou smiled and continued to ask, "And then?"

Helfgott: "And then? Use our distance to measure weights? Then then the periodic table of elements? How to do this is a systematic discipline, I remember called cosmological linguistics, Paris high school seems to be Someone is studying this, but I am not very familiar with that professor..."

"In short, I feel that if we can do basic communication, everything is not a problem. We can exchange foreign students after we have determined that we are not each other's lunch. Once the cultural exchange begins, we can understand soon. each other."

Having said that, Professor Helfgot paused for a moment, shrugged his shoulders and continued.

"And the point of view of music, if they decide to contact us and be able to find us, we have already had some understanding of us. We may even have observed it for a while. Whether it is electromagnetic wave signal or receiving it from us. Postcards, if they really want to communicate with us, they will definitely think of ways."

Lu Zhou squatted slightly and then said with a smile.

"To tell the truth, you can write sci-fi in your brain."

Helfgot haha ​​laughed.

"Thank you for your compliments, but writing sci-fi is interesting to study mathematics, I will leave the opportunity to others!"
