The passionate years starting from the college entrance examination

Chapter 390, Children and Papers
April 1980, Beijing, Cuihua Hutong, Chen’s house.

"Dad, we will definitely win the championship this time and bring glory to the country!"

The two siblings, Chen Xi and Chen An, who were already prepared, spoke confidently to their father.

The International Mathematical Olympiad is an international competition for middle school students. It has been held for 21 years since 1959.

It was initially initiated by Eastern European countries and acquired by UNESCO, and has since been held every July.

In the history of the original time and space, the mainland did not participate until 1985, but in this time and space, the capital city has become one of the three major mathematics centers in the world, and can even be said to be the most influential mathematics center.

Therefore, it is natural that the increasingly influential International Mathematics Olympiad cannot lack this important member from the Mainland.

So the mainland has been involved since the 1970s.

This year is relatively special. The host nation, Mongolia, was originally scheduled to host the competition, but as a result, they had financial difficulties and were suspended.

After the capital learned about it, they directly applied to take over the hosting rights and advanced the hosting date to April.

This competition is hosted by the participating countries in turn, and the funds are provided by the host country, but the travel expenses are borne by the participating countries themselves.

It stands to reason that the capital city has already hosted it in previous years, and it should not be hosted by the capital city again.

But Chen Guohua, the world's top mathematician, spoke up. In addition, he has two children to participate this year, so it is just right.

why?
Because the test questions are provided by each participating country, they are then selected by the host country and submitted to the main examination committee for voting to produce six test questions.

This means that the capital, which is hosting this year's International Mathematics Olympiad, naturally does not need to issue test questions.

As long as there are no test questions, Chen Guohua can perfectly avoid suspicion.

Moreover, the two siblings, Chen Xi and Chen An, do not need to go abroad to participate in the competition, and safety issues are guaranteed.

After all, if you go abroad to compete, usually only six middle school students aged no more than 20 years old will participate in the competition, and two mathematicians will be sent as team leaders.

In other words, there is no such thing as a bodyguard.

If someone wanted to take advantage of this and directly kidnap Chen Xi and Chen An, wouldn't Chen Guohua cry to death by then?
"Okay, okay, you are all the best."

Chen Guohua smiled and encouraged.

His four children are all very good, with good personalities, relatively optimistic and cheerful, and influenced by their family members, the four children are also very positive and have clear goals.

"These are the remaining forty-two practice questions. You can practice them again in the last few days. I have given the problem-solving ideas and reference answers to your mother. After you have finished, go to your mother to get them.
After a pause, Chen Guohua continued:

"I'm going to work. When the time comes, you can participate in the competition by yourself. Relax a little and just treat yourself as if you were doing exercises at home. Don't put too much pressure on yourself."

"Good dad."

The two children nodded seriously, took the exercises and went back to the room.

The training team also has practice questions, and there are a lot of them, but Chen Xi and Chen An often do a few extra practice questions.

Even their team leader encouraged the Chen Xi siblings to bring exercises given by their father to the training team.

After all, the questions asked by Chen Guohua may be better and more comprehensive.

After explaining everything at home, Chen Guohua went to the base in the suburbs of Beijing and prepared to fly to the northwest.

Regarding Chen Yuanchao's illegitimate son Chen Xiaomo, the relationship behind Du Ziqing has not yet been thoroughly investigated, so no follow-up related actions have been carried out.

In addition, it is difficult to say whether Chen Yuanchao failed to resist Du Ziqing's temptation.

Anyway, Du Ziqing is indeed so beautiful that it is understandable that Chen Yuanchao suddenly misfired.

As far as this matter is concerned, Chen Guohua doesn't want to pay attention to it. He also believes that Chen Yuanchao can handle it by himself.

In the northwest, Chen Guohua will stay here for a while when he comes here this time.

The reason is also very simple. After a year, the Nantianmen Space Station project will launch the launch mission again, and he, the general manager of the project, must be present.

There was a major launch accident last year.

Although there were no casualties, no one wanted this to happen again.

"Director, we will definitely be able to get a perfect score of 100 points this time and we won't be held back."

Sun Jiadong and others tried their best to make guarantees in front of Chen Guohua, but the latter just nodded.

After a year of rest, if you still can't reach 100%, then there is no need for this project to exist.

While Chen Guohua was staying in the Northwest for retreat, far away in North America, at the Hunter Family Manor in Dallas, Adolph Hunter was already a little unable to hold on.

After finally waking up and being able to speak a few words, Adolf Hunter immediately gave an order to get his medical team ready. He needed to go to the capital for treatment.

Nelson Hunt, the troublemaker, was directly kicked out of the position of heir by Adolf Hunt.

On the contrary, Ray Lillett was suddenly promoted, and it was announced in advance that the Hunter family business would be handed over to Ray Lillett for management. As for the children such as Hash, Bunker, Herbart and Nelson, they only received money. It would be nice to be a rich man in the future.

Adolph Hunter's movements were very quick, and he kicked Nelson Hunter out of the game with the knife in his hand.

The so-called alliance is self-defeating.

Facing the shadow of death, Adolf Hunter's will to survive also broke out, unprecedentedly strong.

As a result, private planes took off one after another from North America, all destined for Beijing Nanyuan Airport.

When Zhang Jihan received these notifications, he almost fainted from happiness.

But soon, a trouble arose: there were not enough beds in the small hospital of Zhenhua Research Institute!

How to do it?

Arrange it on the spot!
Earning foreign exchange is more important, so beds have been reserved in units such as Union Hospital and the First Affiliated Hospital of Peking University.

It's just that there is only one upgraded medical electronic linear accelerator now, and units like Union Hospital don't have it yet.

From last year to now, it stands to reason that an upgraded version of the medical electronic linear accelerator has been built, but in fact, land shortages have begun to appear in the capital.

Mainly the land in the city is not enough.

Whether it is Union Hospital or the First Affiliated Hospital of Peking University, the places around them are either scientific research institutions or courtyards.

There is no way to acquire land to expand the hospital.

What's more, there is no way to install an upgraded medical electronic linear accelerator within the second ring road, it can only be installed outside the third ring road.

The small hospitals of Zhenhua Research Institute are all located in Wudaokou, which is already outside the Third Ring Road.

In the end, the relevant leaders stared at the map and studied it for a while, then waved their hands and began to adjust the hospital's plan.

Whether it is the second or third ring road, or other places in the suburbs, medical resources need to take care of more ordinary people.

At the same time, top medical resources need to be centralized.

Concentrate your strengths to do big things!
After the fifty top wealthy people arrived in the capital, they were arranged on a first-come, first-served basis.

Adolph Hunter was very shrewd. When he applied, he flew directly to the capital and did not need to transit on Hong Kong Island.

Fortunately, Adolph Hunter's own private jet can fly more than 10,000 kilometers in the air and can fly directly from Dallas to Beijing.

Because of this, Adolf Hunter got a place in the small hospital of Zhenhua Research Institute.

With so many foreigners coming to the capital, and the recent International Mathematical Olympiad competition, the streets of the entire capital suddenly became filled with many foreigners.

The last time there were so many foreigners was before the Liberation War, right?
Even during the period from 1953 to 1958, there were not so many engineers and professors coming from Moscow.

As time went by, two siblings, Chen Xi and Chen An, also began to participate in the competition.

The entire mathematics competition was not long, it lasted for two days, with four and five hours of continuous work every day, three questions every day, and a total of six questions.

Two days flew by and the results came out quickly.

During the closing ceremony of the competition, Erdös, Grothendieck and others all came.

So many big guys came, causing a sensation throughout the closing ceremony.

The team leaders of many countries are mathematicians, but these mathematicians need to respect Erdez and others. After all, these people are famous figures in the world of mathematics.

They are the authors of many textbooks and thesis reference books.

After the closing ceremony began, the chairman of the main examination committee announced the bronze, silver and gold medals. Without much surprise, Chen Xi and the others, representing the Mainland, won the gold medal.

After Chen Xi and the others got their medals, Erdesh came to Chen Xi and Chen An first and said with a smile:
"You should be studying at Peking University in September this year, right? Then why don't you directly study for my master's and doctoral degrees?"

The other four middle school students standing next to Chen Xi and the others couldn't help but cast envious glances.

People are so irritating!
We are all still middle school students, and the two siblings, Chen Xi and Chen An, are only fourteen years old this year. They can actually study for master's and doctoral degrees directly without taking exams. It's amazing!

For these middle school students, there is no need to say more about who Erdesh is.

Who wouldn’t want to be a student of such a master of mathematics?
This means that the future is smooth.

It's a pity that Chen Xi and Chen An don't necessarily need it. After all, their father is one of the top mathematicians in the world.

Bang!
"Erdesh, please don't break the rules. How can you tempt students like this?"

Grothendieck also ran over and slapped Erdös on the shoulder.

Both of them want to become Chen Xi and Chen An's mentors, so even though they have stopped accepting master's degree students for a long time, they have now set this precedent.

Perhaps in the past, they were a little more polite for Chen Guohua's sake.

Now, they have just seen the test papers of Chen Xi and Chen An. Compared with before, the logical thinking ability of the two siblings has obviously improved even more.

With a little training, he might become a top mathematician in the future.

Borsuk, Michael Atiya, Shafarevich and others also came to join in the fun. For a while, the scene was a bit chaotic and a bit funny.

Faced with the "pursuit" of everyone, Chen Xi was also a clever person. First she thanked Erdesh and the others, and then temporarily got rid of Erdesh and the others on the grounds that she still needed to discuss the apprenticeship with her father. entangled.

"Baga, why are those people surrounding them? Huh, what's there to be proud of? Our country will definitely win the gold medal next year."

"God, why do you always care so much about the Orientals? Have you stopped taking care of us?"

"What the hell, China Chen is already so powerful. I didn't expect that his children are not inferior at all. It seems that he needs to adjust his strategy."

The other foreign team leaders and contestants who were watching were all gritting their teeth.

Many people know that Chen Xi and Chen An are the children of Chen Guohua, so now that they have led the team to win the gold medal, no one is too surprised.

As the saying goes, dragons give birth to dragons and phoenixes, and mice's sons can dig holes.

If Chen Xi and Chen An did not win the gold medal, everyone would be very surprised.

But because of this, everyone will be more envious and jealous.

Once only one of Chen Guohua's four children inherits Chen Guohua's mantle and becomes the new leader of mathematics in the East, then Beijing, one of the world's three major mathematics centers, will probably continue to inherit the legacy.

terrible!

Now it seems that all four of Chen Guohua's children have this possibility, and may even surpass Chen Guohua.

In other words, Chen Guohua's influence in mathematics and scientific research achievements are not only amazing, but he is also very good at teaching and educating people. He is simply a replica of Kolmogorov.

In the first half of the twentieth century, Kolmogorov in Moscow was definitely one of the top mathematicians in the world.

The only people who could compete with him were von Neumann, Poincaré, Noether and Hilbert, but these people were far inferior to Kolmogorov in terms of educating his disciples.

As we all know, Kolmogorov’s students include Gelfand, Maltsev, Gnedenko, Arnold, etc., all of whom are pillars of the Moscow mathematics community.

Especially Gelfand, he was the only mathematical figure in the entire Soviet era who could be compared with Kolmogorov and Shafarevich.

From here we can see how powerful Kolmogorov's talent is in teaching and educating people.

And Chen Guohua also has a tendency to develop in this direction. He even gives birth to his own children and teaches them himself.

The two students Chen Shuxing and Bai Ronggen who were taught before are now the backbone of the mathematics community in Beijing.

Although Chen Shuxing and Bai Ronggen have average achievements, they are only for the relatively dazzling Chen Guohua. For many ordinary mathematicians, Chen Shuxing and Bai Ronggen are also giants in academia.

If Chen Guohua hadn't been too involved in scientific research projects, perhaps he would have been able to train more outstanding students.

In today's time and space, Shafarevich, who was born in 1923, has been detained by the capital.

Before that, in 1959, Shafarevich had followed Gelfand and others to attend Chen Guohua's lecture. In 1962, Shafarevich put forward important assumptions about arithmetic geometry. , which is the so-called Safarevich conjecture.

Suppose Then X is said to be well-reducible in P.

The Shafarevich conjecture is that for any finite set S of prime ideals of OK, there are only a finite number of g-dimensional principal polarization Abelian varieties on K under isomorphism, and it has good reduction everywhere outside S. .

After this idea was put forward, it was not widely discussed in the mathematical community. It was not that Shafarevich was not good at it, but that the field of arithmetic geometry was not popular.

In the history of original space and time, the main contributions of mathematicians who won the Fields Medal were almost all concentrated in the three fields of algebraic geometry, topology and partial differential equations.

Even the two major categories of algebra and number theory are relatively few and not so popular, let alone arithmetic geometry?
Mathematics throughout the 20th century actually focused on three major areas: the expansion of pure mathematics, the application of mathematics in space, and the interaction between computers and mathematics.

Pure mathematics is also called core mathematics, and its superior level is abstract mathematics.

To put it simply, pure mathematics is the legacy of the 19th century. According to Bertrand Russell, a British mathematician, there was a crown in the 19th century that could be compared with the use of steam engines and the use of electricity. That must be pure mathematics. discovery.

For example, Fermat's last theorem, which was a sensation at the time, has been pending for more than three hundred years, but it was proved by Chen Guohua in the 20th century.

There are also the four-color theorem, as well as other continuum hypotheses that many people have heard less about, and the classification theorem of complex finite simple groups, etc. have also been proved.

In short, the Shafarevich conjecture is not a popular one, but it is still studied by a few people.

However, at the end of the 1960s, one of Chen Guohua's papers verified the Safarevich conjecture.

After being questioned, Shafarevich was stunned.

You must know that Chen Guohua had already proved the Poincaré Conjecture, Fermat's Last Theorem, Riemann Hypothesis and other major problems of the century, although in comparison, the Shafarevich Conjecture was relatively small.

But it is still a top-level mathematical problem, but it was easily proved by Chen Guohua.

Therefore, Shafarevich, who had been in Moscow for many years, could no longer suppress his excitement and came to the capital to become a professor at the Beijing Institute of Advanced Sciences.

No wonder Shafarevich became a traitor, only because the enemy army was too strong.

Throughout Shafarevich's life, he received an associate's degree at the age of nineteen. After 1943, he worked at the Czechlov Mathematics Institute and did not receive his doctorate until 1953.

He became a professor in the same year, and became a corresponding academician of the Moscow Academy of Sciences in 1958.

However, his mathematical research results are not very strong and can only be said to have just begun.

As we all know, the age when people engaged in mathematical research are most likely to produce scientific research results is before the age of forty.

It was only at the age of thirty-nine, in 1962, that he proposed the Safarevich conjecture.

In other words, if he cannot continue to produce mathematical research results, then this will probably be the end of his life. However, what is there in the capital?

Chen Jingrun won the Fields Medal at the International Congress of Mathematicians in 1970, and Lu Jiaxi won the Fields Medal at the next session, in 1974.

In addition to these two people, there are also Chen Guohua, a top mathematician, and people like Erdez and Grothendieck.

Engaging in mathematical research does not just happen behind closed doors. If Shafarevich wants to go further, he can only get in touch with more top mathematicians.

As for Kolmogorov and Gelfand, they are all older and communicate frequently, so it is difficult to inspire.

Shafarevich came to the capital and soon became the backbone of the Beijing Institute of Advanced Sciences.

Anyway, Chen Guohua’s request for people like Erdesh, Grothendieck, Shafarevich, and Michael Atiyah is very simple: to enrich the professor team of the Beijing Institute of Advanced Science and promote the development of mathematics in the mainland.

These people are engaged in pure mathematical theoretical research, which will not have much impact on the present, but in the future.

Therefore, neither Moscow nor Washington will target these people too much.

However, Moscow and Washington did not expect that Chen Guohua was not even old yet, and his children had already risen and were ready to take over.

Although the two siblings, Chen Xi and Chen An, are still very young, just winning the championship in the International Middle School Mathematical Olympiad does not mean much.

But this just proves that Chen Guohua has a successor.

Just when the team leaders and participating students from various countries were envious and jealous, this Mathematical Olympiad finally came to an end.

By the end of April, Chen Si had also completed writing a paper and submitted it to Journal of Mathematics.

Mathematics research journals such as the Journal of Mathematics in the Mainland have become one of the journals that major institutions and universities around the world must subscribe to.

Just because Beijing is one of the three major mathematics centers in the world, it not only has many top mathematicians, but also Chen Guohua, one of the world's top mathematicians.

The editor-in-chief of the journal is not Lu Qiaoshan, but Li Guangliang.

When Li Guangliang saw that it was Chen Si's paper, he was surprised for a while, and then he began to review it briefly.

Although Li Guangliang knew very well that doctoral students like Chen Si generally would not make such low-end mistakes, this was his job and he still had to check it again.

After confirming that there were no errors, Li Guangliang began to contact the math master responsible for review.

Since the mid-1970s, the Internet began to spread around the world, and email has become one of the communication methods for many people.

As a result, emails also spread to the mathematics community, and soon became a tool for everyone's daily communication.

Chen Si's paper was distributed to mathematics experts in Moscow, Princeton, Great Britain, Paris and other places for review.

This paper is about understanding the algebraic mechanism behind the theory of quantum integrable systems. The reason why Chen Si focuses on algebraic issues in mathematical physics is naturally influenced by her father.

Because Zhenhua Research Institute has long been conducting research and development work on quantum chips, Chen Guohua often pays attention to relevant theoretical research results in the international mathematics and physics communities.

During this process, Chen Si saw relevant papers in the algebraic field of mathematical physics. She and her father Chen Guohua proposed that the key algebraic structure is the algebraic structure of Hopf algebra, and the Hopf algebra related to quantum integrable system theory. Puff algebras are neither commutative nor cocommutative.

Such Hopf groups are often called quantum groups, and they have Poisson-Lie groups as their classical limits.

At that time, Chen Guohua was quite happy after listening to her discussion and asked her to continue her research.

Unexpectedly, she actually came up with the results of her research.

Before she submitted the paper for publication, she specifically contacted her father, hoping to add his name as the corresponding author.

As a result, Chen Guohua gave him a lesson.

The reason is also very simple. Chen Guohua does not need such a paper to make up the numbers. Secondly, Chen Si has grown up and should publish papers independently.

What's more, this paper was originally the result of her own scientific research, and Chen Guohua didn't help much. He didn't even bother to "occupy the magpie's nest" and steal the results of his daughter.

North America, Maryland, Baltimore.

In a beautiful villa at Johns Hopkins University, retired Zhou Weiliang turns on his computer and browses emails every day.

Zhou Weiliang had already retired in 1977.

Prior to his retirement, he served as chair of the mathematics department at Johns Hopkins University for eleven years.

This person is obviously of Chinese descent, but he is not willing to return to the mainland to teach and insists on dying of old age in North America.

Although Zhou Weiliang has retired, he has devoted his whole life to mathematics.

Therefore, even after retiring, he still pays attention to the mathematics community and often chats with friends in the mathematics community.

In fact, he doesn't have many friends, because he is very indifferent to fame and fortune, and rarely communicates with others.

But no matter what, Zhou Weiliang certainly has a few friends.

So he received an email from a professor at the Institute for Advanced Study in Princeton today. When he clicked on it, he was surprised.

"Chen Si? About understanding the algebraic mechanism behind the theory of quantum integrable systems?"

Surprised, he still looked at it carefully.

By now, in 1980, mathematics has reached the end of its golden age.

Starting from the Poincaré Conjecture at the end of the 19th century and the beginning of the 20th century, to Hilbert's Twenty-Three Mathematical Problems, the wave of abstract mathematics swept the world, and with the emergence of computers, the global mathematics community continued to break through the edge of knowledge. , promoting the rapid development of mathematics.

Many mathematical subdivisions such as integrals and measures, functional analysis and general topology, Riemann surfaces, algebra, differential geometry and tensor analysis, probability theory, homologous algebra and category theory, logic and calculation, etc., make mathematics a The branch structure is transferred to another branch, extending hierarchically to form the entire mathematics.

For Zhou Weiliang, he knew that he was in such a golden age. He was very happy and willing to promote the development of mathematics.

Before his retirement, he devoted all his life to the study of algebraic geometry and was one of the important mathematicians in the field of algebraic geometry in the twentieth century.

As we all know, algebraic geometry is the in-depth and development of analytic geometry. Its research object is the solution set of high-dimensional algebraic equations or algebraic equations, that is, n-dimensional polynomials with coefficients within a certain field k.
That is, algebraic varieties. The simplest algebraic variety is a plane curve.

Elliptic functions, elliptic integrals, Abelian integrals, etc. are all related to plane curves. The theory of algebraic functions of complex variables and the theory of Riemann surfaces further promoted the development of modern algebraic geometry.

Chen Si's paper is an algebraic problem in mathematical physics, which also involves Hopf algebra.

Hopf algebras are a class of double algebras, that is, vector spaces with compatible associative and coalgebraic structures, coupled with an epipolar map that generalizes inverse operations on groups.

Therefore, there is no problem at all in asking Zhou Weiliang to help review Chen Si's paper.

In fact, Chen Guohua invited talents like Zhou Weiliang back to China more than once.

But the other party seemed determined to stay in North America, so Chen Guohua had no choice but to let the other party go.

Of course, Zhou Weiliang has retired and is almost 70 years old. It is really not suitable for him to mess around anymore.

In comparison, Chen Shengshen is still more capable of tossing, and he also lives longer, so Chen Guohua is also actively inviting him to return to China to teach.

Chen Shengshen and Zhou Weiliang were both of the same age, born in the same year, and were contemporaries.

However, Zhou Weiliang had already followed his father Zhou Meiquan to study in North America when he was only thirteen years old, and was more heavily influenced by Western ideas.

Because of this, Chen Shengshen still recognized his Chinese identity more, but Zhou Weiliang did not recognize it so much.

In addition to Zhou Weiliang, who was reviewing Chen Si's paper, there were also Chen Shengshen, Lev Pontryagin, Andre Weil, Paul Cohn and others.

Even here in the capital, Grothendieck and the others got Chen Si's paper as soon as possible.

In less than half a month, Chen Si’s paper was published.

The efficiency of this review is still very high.

No way, who told her father to be Chen Guohua?

Although Chen Guohua did not speak, the entire mathematics community was very willing to open a backdoor for her and give priority to reviewing her papers.

The paper is very good, and this scientific research result has a lot of influence.

If she makes greater breakthroughs in the field of mathematics in the next two years, she may be able to win the 1982 Fields Medal.

In Beijing, because of Chen Si's paper, her name began to appear frequently in the mathematics departments of various universities, the Chinese Academy of Sciences, the Beijing Institute of Advanced Sciences, Zhenhua Research Institute and other institutions.

"As expected of the director's daughter, she is so amazing. I remember that Chen Wei also published a paper, right? But it seems a little behind his sister."

"Professor Chen is not only able to do his job perfectly, but his work in educating children is also a model worth learning from."

"We all carry one head on two shoulders. Why is the gap so big? Where did we lose?"

Whether it is Peking University or Zhenhua Research Institute, everyone who knows Chen Guohua is talking about this matter.

And the news finally reached the Northwest.

Qian Xuesen couldn't help teasing Chen Guohua with his paper:

"Let me tell you, Director Chen, how much of your legacy will your daughter inherit? I think you, an old father, will soon be surpassed by your daughter."

Before Chen Guohua could speak, Guo Yonghuai couldn't help but interjected:

"Brother, let's not talk about transcendence or not. Director Chen, I remember that your daughter Chen Si is nineteen years old this year, right? She seems to be unmarried?"

As soon as these words came out, several professors or chief engineers who had sons or grandchildren of school age couldn't help but "recommended themselves".

For example, Wang Xiji has a son, Wang Cunxiao, who is one year older than Chen Si. He is currently working as a researcher at the Aerospace Technology Research Institute in Shanghai, the Eighth Academy.

It can be said that he and Chen Si are very suitable and well matched, which can be regarded as a good marriage.

When Chen Guohua heard this, he said in a dumbfounded voice:

"Thank you for your enthusiasm. It's not that I'm not happy. You have to ask the child what she wants in this matter. Let's ask your wife to contact my family. She will be happy to take over these matters."

"Whether it will happen or not is not up to me, and don't ask me. I have never interfered in this matter, and I can't. My eldest son did it before."

He mentioned the marriage between Chen Wei and Tao Zi. At the beginning, Chen Wei was very reluctant to go on a blind date. Whenever the matter of a blind date was mentioned, he was like a gourd, unwilling to speak.

In comparison, Chen Si is indeed very busy and very hardworking, because her goals are very clear.

Just because she is a girl, if she wants to have a better development in the scientific world, she must do it while she is young.

So she worked hard on scientific research, and finally came up with such a paper this year. It seems that her Ph.D. is stable.

Even Peking University or the Beijing Institute of Advanced Science will take the initiative to hire her as a professor.

Of course, although Chen Guohua is a professor of mathematics at Peking University and the dean of the Beijing Institute of Advanced Sciences, he does not care about these things. At least when it comes to hiring Chen Si as a professor, he, a father, will definitely avoid suspicion.

After becoming a professor, Chen Si will focus on scientific research in the future, and personal matters for his children may not come so early.

After all, according to her mother, the best age for women to have children is actually between the ages of twenty and twenty-eight.

In this case, Chen Si has a clear goal. It is very likely that he will not consider marriage until he is around 24 or 5 years old, or even after he has achieved certain results.

Seeing what Chen Guohua said, Qian Xuesen, Sun Jiadong, and Guo Yonghuai all changed the subject wisely.

No one likes to gossip, but chatting occasionally is the 'spice' in this boring work.

Chen Guohua glanced at Guo Yonghuai, then quickly looked back.

This time and space has indeed changed a lot from the original time and space.

Although Zhao Jiuzhang did not persist and left early, Guo Yonghuai and many others did not leave. They stayed in their respective units and continued to do their own scientific research work.

For example, Guo Yonghuai, in the original history of time and space, died in a cornfield a few kilometers away from Nanyuan Airport in Beijing in 1968.

But now, he is still alive and well, without any accidents.

"Director Chen, Leader Zhang's phone number."

In the command room, Yan Shouchun, who was helping to hold the mobile phone, came over and whispered.

Zhang Jihan called and asked whether the next launch mission of the Nantianmen Space Station would proceed as scheduled.

"Leader, I promise there will be no problem. I'm still waiting to complete the launch mission and go back to spend Children's Day with my eldest grandson."

Hearing Chen Guohua's words, not only Zhang Jihan on the other end of the phone was speechless, but also Yan Shouchun next to him couldn't help but twitch the corner of his mouth.

Chen Guohua really loves Chen Ce, his little grandson, but he is now in the northwest and has been busy with work, and can only make video calls every other week.

But the fact that he said he wanted to go back and spend Children's Day with Chen Ce was indeed true, and he would say it every time.

"Since you can ensure that the launch mission is not delayed, then there is no problem." Zhang Jihan ignored the Children's Day and Chen Ce and continued to talk about work.

One is the upgraded version of the medical electronic linear accelerator.

Ever since wealthy people like Adolph Hunter came to the capital from North America and other parts of the world, the number of 'tourists' here in the capital has soared by 30%.

After the reopening in 1978, the number of foreign tourists visiting the mainland has indeed increased a lot, but it is also very limited.

After the year of 1979, with the rapid development of the national economy and the deepening of opening up to the outside world, the number of foreign tourists in coastal cities such as Baiyun City and Shanghai has increased at a faster rate.

But the capital city is still relatively small.

But what is surprising is that this year, an International Mathematical Olympiad for middle school students and the arrival of wealthy people like Adolf Hunter really kicked off the peak competition for Beijing tourists.

In the two months of April and May, the number of foreign tourists visiting the capital exceeded 800,000, setting an extremely terrifying record.

The increase in foreign tourists was originally a good thing.

During this process,

Based on this, Zhang Jihan certainly needs to remind Chen Guohua.

The latter didn't say anything after listening.

He believed that Ge Shouzhi could handle these matters well.

Zhenhua Research Institute is not an ordinary organization, and anyone who can be bribed will not end well.

Just because Chen Guohua had formulated relevant policies earlier, as well as many high and new technologies, the cost of crime has become very, very high.

Secondly, the salaries of researchers at Zhenhua Research Institute are not low, and their living standards in the capital are not low.

Finally, there are many courses such as patriotic ideological education. In addition, every researcher who joins Zhenhua Research Institute will abide by tradition and first undergo military training for three months or half a year.

From these aspects, Zhenhua Research Institute has done a good job.

Due to many reasons such as adequate supervision, adequate ideological education, and the high cost of crime, it is easy to dissuade those wavering losers.

In addition, the upgraded medical electronic linear accelerator is not an ordinary technical equipment. How could the technology be easily stolen?

This is the crystallization of the high-end manufacturing industry. Not to mention that the technology is difficult to obtain, even if you have the blueprints and technology, it does not mean that you can create it.

"The second thing."
