After visiting Academician Pan and unexpectedly gaining some ideas and directions for strongly correlated electronic systems, Xu Chuan also left with Yang Qiu.

On the campus of Peking University, Mr. Yang got in the car first to say goodbye and left accompanied by Ms. Weng because his legs and feet were not very convenient.

It was Mr. Qiu, who was ready to continue chatting with Xu Chuan and walking all the way back to Shuimu.

On the campus of Peking University, Xu Chuan naturally accompanied the old gentleman all the way, and the two chatted, he remembered something and asked:

"By the way, Old Qiu, about the meeting you mentioned last time to advocate sorting out mathematical knowledge and giving life to those ancient mathematical knowledge, hasn't you set a time yet?"

Mr. Qiu shook his head and said, "There have been two more meetings on the IMU side, and they are still discussing. ”

"You know, if this kind of conference is put in China, the country naturally hopes to hold it in a big direction, so I hope that the IMU will invite more top mathematicians to expand its influence."

"Of course, the International Mathematical Union naturally hopes to take advantage of this opportunity to expand the influence of mathematics, so it is constantly discussing revisions, resulting in the time has not been determined."

After a slight pause, he continued: "But judging from the results last time, it should be soon, probably around January after New Year's Day." ”

"I'll let you know when the time is confirmed."

Xu Chuan nodded with a smile and said, "No problem." But speaking of which, didn't Peking University take the lead in this kind of meeting? ”

If you want to talk about the influence and strength of the mathematics department of domestic universities, Peking University is indeed unique, and there is nothing to say about this.

Whether it is domestic status or international influence, the Department of Mathematics of Peking University has surpassed Mizuki a lot, and sometimes, the ranking of Mizuki Department of Mathematics in China will even fall out of the top three.

This kind of conference, which is quite influential in the world, should be held at Peking University according to common sense, after all, Peking University is the window of the Chinese mathematical community to the outside world.

Hearing this, Mr. Qiu snorted coldly and said, "They want to do it, but I facilitated this exchange meeting, so why give them a chance." ”

"And façade aside, in terms of influence, among the top international mathematicians, they can't make this kind of conference."

Speaking of the old gentleman of Peking University, he is a little dissatisfied, and the friction between him and the Department of Mathematics of Peking University is also well-known.

If you want to talk about comprehensive strength, the Department of Mathematics of Peking University is indeed the first among domestic universities.

However, if you want to talk about the influence of top mathematicians in the world, after the death of Mr. Chen, Peking University as a whole is still lacking.

Whether it is Xu Chuan or Qiu Chengtong, among the top level mathematicians, their influence is much stronger than that of Peking University.

After all, the seven millennial problems and the name of the Fields Medal winner are there, which Peking University can't catch up with no matter what.

Xu Chuan smiled and didn't answer, the two skipped the topic and walked forward while chatting.

Suddenly, Xu Chuan noticed the figure of a young man, who looked very familiar, a little old.

He stopped and squinted his eyes, and suddenly shouted, "Lu Tianrui, here." ”

On the side of the road, Lu Tianrui, who was hurriedly walking on the campus with a book in his arms, heard the shout and looked over, and two familiar figures, one young and one old, were standing on the other side of the road looking at him.

After staring at the two of them for a while, he seemed to recognize their identities, but he couldn't believe that they were here.

After rubbing his eyes and confirming that he was not hallucinating, he quickly ran over and asked excitedly and tremblingly, "Brother Chuanchuan, is it really your old man?" ”

After saying hello, he greeted Mr. Qiu, who was standing with Xu Chuan, and said solemnly: "Hello, Professor Qiu." ”

Looking at some familiar figures in front of him, Xu Chuan sighed a little.

The person I met here was a friend who participated in the IMO competition together in high school, and six or seven years have passed, and the little fat man has grown up.

The only thing that remains unchanged is the chubby body shape and round glasses perched on the bridge of the nose.

"I didn't expect to meet you at Peking University, last time you told me that you were going to apply for Princeton, I thought you were going to study abroad." Looking at the little fat man in front of him, Xu Chuan sighed with a smile.

As his teammate, Lu Tianrui, who won the gold medal in the CMO competition together, has no doubt about his talent in mathematics, and he will naturally go on the road of mathematics after being recruited by Peking University in advance.

Lu Tianrui nodded and said, "It's really fast, I'll have to go over in January next year." ”

Xu Chuan smiled and said, "Amazing, did you study for a doctorate in the past?" Six years to finish college and graduate school, which is very good. ”

Hearing this, Lu Tianrui scratched his head a little embarrassed and said, "I have already obtained a doctorate degree from Peking University, and this time I studied in the past." ”

Hearing this, Xu Chuan was a little surprised: "Yes, Xiao Tianrui, this β is a good pretend, and he has completed all his studies in six or seven years." ”

Lu Tianrui: "Compared with Brother Chuan, it's too far behind." ”

On the side, Mr. Qiu Chengtong said with a smile: "It takes six years to complete a university postgraduate doctorate, which is already very powerful." Don't compare yourself to this monster, he's not a normal person. ”

After a pause, he then looked at Xu Chuan and said with a smile: "I have time to go to Shuimu to talk to me, so I won't bother you two young people today." ”

Xu Chuan nodded and said, "It will definitely be." ”

Mr. Qiu smiled and waved his hand, nodded at Lu Tianrui again, and then walked away with his hands behind his back.

"Let's go, find a place to sit."

Mr. Qiu left, and Xu Chuan smiled and patted his teammate on the shoulder.

Although the prestige of the two has always been in occasional contact, they haven't seen each other for six or seven years, and it is still very joyful to meet unexpectedly, especially the friendship that came together in the past.

In front of a bubble tea shop on the campus of Peking University, the two found a quiet place to sit down, looking at the former friend in front of them, the current giant, Lu Tianrui also felt a little emotional.

The great god who took him to the competition back then has really become a great god now.

Although he knew the gap between the two a long time ago, he didn't expect the gap to be so big.

While still studying, the great god has solved two millennial problems, won the Fields Medal, the Nobel Prize, and served as the chief designer of the controlled nuclear fusion project to solve the problem of the century.

The gap between them, I'm afraid it can't be calculated in years, if you insist on it, you can only say that they are two different species.

After all, even if he thought that his talent for mathematics was okay, he never thought that he would be able to solve a millennial problem in this life.

And the teammate in front of him, who is only one year older than him, has already solved two.

If it weren't for some of the friendships left by participating in the competition together, it would have been so restrained that he wouldn't even know what to say.

After chatting for a while, he also let go a little, looked at Xu Chuan and asked curiously, "Brother Chuan, why did you come to Peking University?" ”

He knew the contradiction between the Department of Mathematics of Peking University and his god-friendly teammate, but he didn't expect to encounter it on the campus of Peking University today.

Xu Chuan smiled and said, "I know Mr. Pan Deming from your school, and I came to visit him this time, but I didn't expect to meet you by chance." ”

After a slight pause, he continued: "I will go to Princeton next year, in which direction are you going to study?" ”

Lu Tianrui: "At present, the chosen direction is algebraic geometry, if there is no accident, I should try to go deeper into this field." ”

"Well, algebraic geometry is a very broad field." Xu Chuan said with a smile.

Lu Tianrui nodded and said, "Speaking of which, I was still influenced by you to embark on the road of studying algebraic geometry, and your research on the Hodge conjecture has given me too much shock and inspiration. ”

After a pause, he continued: "I have read Brother Chuan's paper that proves Hodge's conjecture, but unfortunately there is not one out of ten who can understand and understand. ”

Xu Chuan smiled and said, "The proof of Hodge's conjecture is indeed more complicated, and it involves many fields of mathematics. I'll send you some books and manuscript papers that I used to study algebraic geometry when I get back, and maybe you can see the path I've traveled before. ”

When he was studying at Princeton, he left behind several large boxes of books and papers that he had read and studied, which were later shipped back by mail.

For him now, those things are useless, but the words given to Lu Tianrui should help him go further in the field of algebraic geometry.

After all, there are a lot of his thoughts on the problem and some research ideas.

Hearing this, Lu Tianrui also swallowed with some difficulty, he naturally knew how precious these things were.

Not to mention to students like him who are still in the learning stage, even to top mathematicians, maybe it will be helpful.

But it was hard for him to refuse, after all, for a mathematical researcher, such a gift was unwanted.

Seeing this old friend's entanglement, Xu Chuan smiled and said, "Don't be polite to me, anyway, those things that used to be left there are idle." ”

Hearing this, Lu Tianrui took a deep breath, nodded solemnly, and said, "Then thank you, Brother Chuan." ”

Xu Chuan smiled and said, "If you encounter any problems in mathematics, you can come to me." ”

The two chatted again, and suddenly, Lu Tianrui looked at Xu Chuan curiously as if he had recovered his previous personality, and asked, "Brother Chuan, how does it feel that you won the Nobel Prize and the Fields Medal together?" ”

Hearing this question, Xu Chuan thought about it seriously before replying, "It's okay." ”

Hearing this answer, Lu Tianrui was stunned for a while, thinking that he would have a lyrical feeling, but he didn't expect it to be just such a sentence.

But then, he reacted again.

Sure enough, let the time change, Brother Chuan is still the same Brother Chuan during the competition, the same against the sky, the same indifference, but the pretending β is more fluid and natural.

Bidding farewell to the old friend he met by chance, Xu Chuan returned to the Beihai Hotel and began to sort out the exchanges and harvests with Mr. Yang and Mr. Qiu today.

Without him, these two old gentlemen can be said to be the first people in China to distinguish between physics and mathematics today.

Even if it is put into the world, these two old gentlemen are also the top batch.

The ideas put forward by a big bull of this level are naturally well thought out, and even for him, they are extremely valuable.

The days passed day by day, and in the blink of an eye, the New Year's Day of the 22nd year arrived.

In this new year of the solar calendar, Huaguo ushered in a new departure.

The Daybreak Demonstration Reactor in Jinling was officially transformed into Huaguo Fusion Energy Company, and the Daybreak Demonstration Reactor completed the final grid connection work, and began to provide a steady stream of electricity to the entire Jinling City.

Of course, supplying a city, even a provincial center like Jinling, is not the limit of dawn.

When all four generating units at the Daybreak Demonstration Reactor are in operation, the full load of power generation is enough to supply energy to the entire Sujiang province.

And with the official connection of the dawn demonstration reactor to the grid, there is another good news.

"Huaguo and Pakistan Railway signed a cross-border power grid interconnection project! 》

"Huaguo negotiated with Laos, Cambodia and other Southeast Asian countries on cross-border power grid interconnection projects. 》

The two pieces of news have caused a lot of turmoil all over the world.

This news is definitely not good news for other countries except China and the countries that cooperate with it, especially for Western countries led by the United States.

Atlantic Coast, White House.

The elderly president was holding a newspaper in his hand, and he didn't know what he was thinking when he looked at the news on it.

At this moment, China began to export energy to other countries, which means that they are starting to squeeze the resources of other countries in Southeast Asia.

Especially for the United States, the small countries in Southeast Asia are an important means for them to contain each other.

It would be nothing if China had just signed a cross-border grid interconnection project with Pakistan and Railways to provide it with cheap electricity. After all, one Pakistani railway is far from enough to affect the situation.

But when the whole of Southeast Asia falls to China, the situation in Asia will gradually and completely collapse.

Not just Southeast Asia, but other countries.

In the face of cheap electricity, not to mention these small countries in Southeast Asia, even the European Union, as long as the conditions proposed by China are not so excessive, I am afraid it may not last long.

After all, the EU's urgent shortage of energy is an urgent matter.

While switching the lifeblood of energy from Tsarist Russia to China is also not a good thing for them, it is not unacceptable if the price of energy can be significantly reduced.

Although everyone is now catching up with controlled nuclear fusion technology, no one knows how long it will take for countries to catch up with China in this area.

It could be ten years, it could be twenty years, it could be longer.

In the meantime, it is not impossible to say that some countries will directly trade core technologies to get support from China, and it is not impossible to build a controllable fusion reactor in China.

After all, for many countries, judging from the dawn fusion reactor that has been realized, a large fusion reactor can generate enough electricity per year to supply a small and medium-sized country.

For the United States, every time they lose a country, it means that their influence in the world is weakened by one point.

This is undoubtedly an even worse change for them, who have begun to go downhill.
