The End of Technology

New semester, new atmosphere.

The campus of the Sports University has become more lively with the addition of many departments.

At this year's orientation ceremony, Ning Zi refused to speak on stage as a student representative, but it didn't matter, his spirit was still there.

During the principal's speech, Chen Yonggang enthusiastically shouted the slogan "This century has officially entered. The world's scientific development depends on China, and China's development depends on the university!" This probably also means that the sports university official has officially begun to clearly support the speech Ning Zi delivered at the freshman conference as a freshman representative last year.

The video was quickly posted online.

Netizens with good intentions have liked almost all the 985 schools in China on Weibo. There are always those who like to watch the excitement, hoping to see the reaction of the most powerful schools in China, and then eat melon seeds while eating them. .

However, this time it was obviously a miscalculation, and the matter could not be provoked in the end because no one took the initiative.

Shuangdan University updated its Weibo on the same day, quoting the original text of "The Aftertaste of the Peach Blossom Fan Leaves the Pavilion Banquet and Takes a Break to Beat the Evil": "See the orioles in the Jade Palace of Jinling at dawn, and the flowers on the Qinhuai Waterside Pavilion bloom early, who knows how easy it is to freeze... …I once slept in this mossy and green tile pile; I have watched the rise and fall of fifty years; in the Crow Clothes Alley, there is no king; the ghosts in Mochou Lake cry at night, and the owl roosts on the Phoenix Terrace. The dream of the ruined mountain is the most real, the old scene It’s hard to throw away.”

Excited netizens immediately started to popularize science with everyone in the comment area. The ellipsis section is the famous "Seeing him building a Zhulou, watching him entertaining guests, watching his building collapse!"

It is a pity that after netizens popularized science in the comment area, the editor of Shuangdan University’s Weibo carefully deleted the Weibo.

Although many pictures have been intercepted, they have been deleted. The imaginary Internet war of words failed to break out after all, which makes many people feel regretful. But it doesn't matter, naturally there are jokesters who come out collectively, which makes the Internet a lot lively after all.

Jokes such as the rise of the physical education teacher eventually became popular on the Internet.

However, Internet hot spots come and go quickly after all.

Not to mention that many strange things happen every day. Many idols in China are worried about hot searches on the Internet and never hesitate to come forward to attract public attention. Even if you often have to apologize for occupying public space afterwards...

So after several well-known idols made all kinds of troubles, the enthusiasm of netizens also began to dissipate, and they began to discuss the scandal between XX and XX today, and the time management tomorrow, which is enough to shock the eyeballs. Gossip news.

This is probably human nature.

Although technology is important, it is difficult for ordinary people to feel its importance. It's like everyone thought chips were very important when they were restricted, but once the restrictions were lifted, few people would pay attention to chips anymore.

At least before computers and mobile phones are used normally, how many people will really pay attention to whether China can make chips every day?

Not important, not at all.

For most people, no one will invest much energy in paying attention to these things as long as it does not affect their daily life.

It's just a matter of seeing it and complaining. After all, how hundreds of millions of transistors are arranged to achieve one function after another is impossible for people with insufficient brain circuits to understand.

People who happen to be qualified to study these things are too lazy to educate everyone on these things online.

After all, the IQ gap between humans can really be greater than that between humans and dogs.

Ask a chip engineer to chat online about the impact of quantum physics on chip development, and there is a high probability that he will end up in the same dilemma.

The uneven development of human intelligence determines that in this world, one percent of the people have always determined the direction of civilization development, while the remaining 99 percent of people have ignorantly moved forward with the times. Life lasts less than a hundred years. As long as you don’t think about the past and the future, what you care about after all is content that is closer to life.

After all, celebrities' scandals are more interesting than science. Everyone can enjoy celebrities' scandals, but science is something that not everyone can participate in the discussion. Even if substances are replaced with scientific terms, they may not be understood. If the necessities of life activities that can be seen everywhere are replaced with academic names, it will make people feel uneasy.

For example, when a solution of 0.9% hydrohydroxy acid and sodium chloride is made, many people think it is not a good thing at first sight, but if it is physiological saline, they probably think it is quite good.

This is probably the current situation.

So when the leaders of the World Semiconductor Alliance began to choose to visit China, most of them were mentioned in the news. As long as no one deliberately stirred up the heat, it was probably discussed in a small area.

…

Yes, the president and CEO of the World Semiconductor Alliance, represented by Intel, began to visit China frequently.

The banners used are different, whether it is inspecting laboratories or production bases in China, these superficial excuses are all pretty good.

Of course, as a country of etiquette, China has no one to expose the true thoughts of these people.

Basically, when people come, officials will naturally come to receive them.

The chip research center built by Apple for the National Sports University is naturally a must-see.

Ning Zi also met many big guys in the laboratory. As he said before, he was not responsible for discussing business issues with these big guys.

Basically, when someone comes, if the other party asks to visit Ti University or Ning Zi, then they will meet in the laboratory, everyone will say a few words, and then Ning Zi will treat the guest to a meal and give him a gift before leaving. A small gift. The gift is a chip made with the latest technology in the laboratory, a radio frequency chip that has been advanced from 160nm to 75nm.

In fact, it is not valuable, but considering that the two first-generation 160nm industrially manufactured narrowband chips can be sold for a high price of 30 million U.S. dollars, the chips presented this time have higher technical content and naturally higher value. At least they indirectly help these Internet companies. The boss saved hundreds of millions of dollars.

It's enough to show how generous Ti Da is.

Of course, that's all Ning Zi did.

If you want to talk about other things, you can only get one sentence: "I'm sorry, I am just a pure student and don't understand anything. When talking about cooperation and business, there are dedicated people to connect with you. If you want to talk about technology, you can talk about it. .”

Then he casually inquired about the other party's business secrets, and the other party retreated.

On the contrary, the commercial department took this opportunity to win many large orders at very favorable prices. The University of Sports has also finalized a large-scale supercomputing cooperation project with the visiting big guys.

Saying goodbye to these tedious administrative tasks, Chen Lili almost understood Ning Zi's graduation thesis through intensive discussions at at least three group meetings a week. In the winter of 2018, when the semiconductor debate came to an end, the date and location of Ning Zi’s doctoral thesis defense had been determined, and it would be held in Ningyuan on Christmas Eve.

…

December 24, 2018, Monday, Yanbei University of Sports.

For many college students who are full of youthful spirit and like to celebrate holidays and lively, today is indeed a very important day, Christmas Eve.

Especially for young people who are in love, today is another date day.

In many cases, it cannot be said that Chinese young people worship foreigners and always like to celebrate foreign festivals. Most of the traditional Chinese festivals are themed around family reunions and are quite serious. There are not many festivals that are really suitable for young people to go out and celebrate lively.

The theme of the Spring Festival is family reunion, the theme of Mid-Autumn Festival is family reunion, and the theme of Dragon Boat Festival is still family reunion. Even if it is Qingming Festival, it is best for the whole family to go out to worship ancestors, so that the reunion can be more complete.

It’s just a Chinese Valentine’s Day, and the romantic theme of meeting on the Magpie Bridge sounds good, but if it’s not a holiday, no one reminds it, and it’s very easy to forget. Although it has been hyped by merchants for many years, it has not caused any big hits. Festive atmosphere.

However, it was finally determined that it was not Ning Zi’s idea to defend his thesis on Christmas Eve. It was mainly because he had to use the time of some academic leaders to participate in the defense.

Although generally speaking, the reviewers of graduation thesis are anonymous, Ning Zi still knew the identity of the reviewers. Chen Lili found two reviewers, both of whom are two big figures in differential geometry in China. Su Zhiming and Shi Fushen are both senior academicians of the Chinese Academy of Mathematics. But it's hard to say whether this is Ning Zi's face or Chen Lili's.

As for the composition of the defense committee, it is even more exaggerated. It is still a super luxurious lineup of all academicians.

For example, the defense chairperson Lu Zhengyue, the defense secretary Fan Zhenhua, and the expert judges besides Su Zhiming and Shi Fushen also include Ruan Zhiju, Zheng Yansi, Hu Zhihao, and Yuan Jingheng.

Basically, all the defense committee members are academicians, and most of them are veteran academicians, except for Ning Zi’s mentor Chen Lili, who is not an academician.

The only younger one, Yuan Jingheng, is 46 years old this year, and he has just solved a world problem in complex differential geometry, which is when the spring breeze is unlimited.

You can imagine how high the standards for Ning Ji's doctoral thesis defense were.

Moreover, today is also the special day for his doctoral thesis defense. There is no one else, and he has only one day to defend it.

Therefore, Chen Lili notified Ning Zi early that his defense process was different from that of other doctoral students. Since his thesis was a relatively novel topic, the reporting time could be extended to 120 minutes. You should know that for a general doctoral thesis defense, the report time for applying for a doctoral degree must generally be controlled within 40 minutes.

Of course, there is nothing that can be done about it. After all, Ning Zi's graduation thesis is more than 70 pages, and both he and the reviewers think that there is not much that can be saved. If we really want to finish it within 40 minutes, we can only follow the process. If you go through it quickly, you won't be able to leave many memory points for discussion.

Anyway, today was a thesis defense for one person, so Ning Zi was given two hours to perform. Therefore, the start time was relatively early. The thesis defense officially started at 8 o'clock in the morning. As for when it would be completed, Chen Lili did not mention it, and Ning Zi did not ask. After all, there is no such thing as failure, so naturally it is impossible to be nervous.

Ning Zi climbed out of bed at 6:50 in the morning as usual.

The only difference was that Lu Xiaoya, who always liked to sleep until eight o'clock before getting up, also got up early with Ning Zi.

After washing up, she urged Ning Zi to put on the formal clothes that she went to pick out yesterday with the two sisters of the Ning family - a set of expensive brand-name tunic suits.

After all, the entire doctoral thesis defense must be videotaped.

Moreover, it is said that many master's and doctoral students from Huaqing and Yanbei have applied to observe Ning Zi's doctoral thesis defense. Of course, this is normal. After all, it is a rare opportunity to be in the same room with eight academicians of the Hua Xia Institute of Mathematics and two future associate academicians.

No one doubts that Ning Zi can become an academician. As for Chen Lili... Ning Zi can become an academician. There is no reason why his mentor can't become an academician in the future.

After all, he was the mentor chosen by Ning Zi himself.

Lu Xiaoya also plans to attend this defense. Not only her, but Ning Xiao also made an appointment with her yesterday to participate in this meaningful day for Ning Zi.

Of course, if she chooses to participate, Zhai Qiuxian will also go...

So she has her own mission.

As for Ning Zi, he didn't have to wait for Lu Xiaoya. He had to go to Ningyuan to do some reception work first.

…

At 7:55 in the morning, Lu Xiaoya, Ning Xiao and Zhai Qiuxian walked into Lecture Hall 507 of the Ningyuan Building from the back door almost without stopping.

This is also the place where Ning Zi will defend her graduation today.

There are very few seats left in the medium-sized lecture hall, which can accommodate a total of 120 people.

But this is not a problem for the three of them, because someone has already occupied their position for them.

"Xiaoya, this way."

The one who called out was Zhuo Mingqian. He had actually returned to the capital from the west of Nanhu where he was teaching during the summer vacation, but Ning Zi was still on her honeymoon at that time and had no time to pay attention to him.

After school started, he was assigned to do some administrative work with the chip R\u0026D center in Ningyuan, learn management experience, and prepare a doctoral thesis. Now he is waiting for the official opening of the Ten Thousand Mu Research Base of the University of Science and Technology, and will be responsible for the coordination and management of various laboratories.

With the Ningyuan staff hanging on the sign, it was natural to help the three of them get a good seat early.

"Brother Zhuo, good morning." Lu Xiaoya walked over with March and the two of them in her arms, and said hello to Zhuo Mingqian.

"Hey, morning, Ning Xiao, and this beauty, morning too!" Zhuo Mingqian quickly glanced at Ning Jiehou who was surrounded by a group of old academicians in front of the lecture hall, and followed the three with a bright smile. The beauties said hello together.

Although he had chased Ning Xiao before, and Ning Xiao was now engaged, and her husband was sitting in front of her, with Zhuo Mingqian's temperament, he obviously would not feel embarrassed about something that had not happened in the past.

Ning Xiao also has a cheerful personality. Not to mention that the two of them have never been in love. Even if they have been in love, they have already let it go after such a long time. He waved to Zhuo Mingqian generously, and then sat down next to Lu Xiaoya. Around her, only Zhai Qiuxian maintained her usual cold demeanor and completely ignored Zhuo Mingqian's warm greeting.

It's just that Lu Xiaoya and Ning Xiao competed for the seat too quickly, so she could only sit next to Zhuo Mingqian.

"Hey, hello, beauty, let me introduce myself. My name is Zhuo Mingqian. I have a PhD in exercise science from the National Sports University. Seeing that you have such a good figure, you must be exercising regularly, right? You can consult me ​​on how to train scientifically. I am unmarried, even I don’t have a girlfriend, so you don’t have to worry about disturbing me at any time, let alone misunderstandings.”

Obviously a year of teaching experience has not completely polished off this person's edges and corners, he is still so familiar.

But this time, she obviously hit a snag. Zhai Qiuxian just glanced at Zhuo Mingqian and then turned her attention to the front of the lecture hall.

"puff……"

Zhuo Mingqian didn't feel embarrassed, and Lu Xiaoya, who was sitting next to Zhai Qiuxian, couldn't help laughing.

But the kind girl took the initiative to introduce Zhuo Mingqian before he was embarrassed: "Well, Brother Zhuo, this beautiful sister is my best friend, her name is Zhai Qiuxian. I can only help here."

"Zhai Qiuxian, this is a good name, and the person lives up to her name. The Sui Dynasty and the Liu Dynasty passed through the autumn, and Yan sang operas and was pretty..."

"Shut up! It's about to start!"

When Zhuo Mingqian was shaking his head and preparing to comment on the name, Zhai Qiuxian turned around and said to him coldly. Zhuo Mingqian immediately shut his mouth because in the lecture hall, the defense chairperson had already stepped onto the podium.

If you say anything else, this is really disrespectful to Ning Zi.

…

"...In this article, I will conduct a targeted study on a type of Kahler-Ricci flow with singularity - conical Kahler-Ricci flow. We will mainly discuss the existence and convergence of its long-term solution .

At the same time, we will also discuss it in conjunction with wisted Kahler-Ricci flow. Using the smooth approximation of the flexed Keller-Rich flow, we obtain the existence of the long-term solution of the cone singularity Keller-Ritchie flow, and then by appropriately improving the Perelman estimate in the case of smooth Keller-Ritchie flow, we discuss the Fano manifold Convergence properties of cone-singular Keller-Richie flows. "

When the defense chairperson finished introducing the agenda, Ning Zi walked up to the podium and began to make a report.

Obviously, for non-mathematical students, these contents are long and boring, and this report is probably no different from a bible.

Take Lu Xiaoya for example. In the first ten minutes, she was still secretly taking photos of the podium with her cell phone. After ten minutes, she was already sitting in her seat and yawning, and her upper and lower eyelids visibly started to fight. It wouldn't be surprising if he started snoring slightly after a while.

Cousin Ning Xiao was not much better and looked like she was about to fall asleep. Zhai Qiuxian was very energetic, but her attention was obviously starting to lose focus...

Among the four people in the last row of the lecture hall, Zhuo Mingqian was probably the only one who listened with interest.

This made Zhai Qiuxian, who was sitting next to Zhuo Mingqian, very curious. Her work required maintaining concentration, but the content of Ning Zi's report was too boring, so she couldn't help but ask softly: "Can you understand?"

"Ha, are you kidding me? If I could understand these things, I wouldn't have taken the physical examination back then. This is simply not something that normal human brain circuits can understand."

"Then you can still listen so carefully?"

"Don't you understand this?"

Zhuo Mingqian suppressed his voice, tilted his head slightly, and whispered in Zhai Qiuxian's ear: "Don't listen to what Ning Jie said, you can look at the old men in the first row. They are all academicians, although you can't see them. But you can carefully observe their movements, like the one on the far left, I’m doubting that he even understands. Do you suddenly feel like you’re not that stupid anymore?”

"Oh why?"

"If you look at other academicians, they will whisper to each other and discuss a few words from time to time. The third one from the left will occasionally take a pen to take notes, but if you look at him, his posture has not changed until now... To tell you the truth, I hold group meetings When I was young, I was also in a daze like this when I listened to other senior brothers talking about the Book of Heaven.

The most important thing is that I tried it on the stage yesterday and could see clearly everywhere. So even though I don’t understand it, I still have to look somewhat literate..."

Zhai Qiuxian was speechless by Zhuo Mingqian's analysis.

Not to mention, when she followed Zhuo Mingqian's method to pay attention to the thesis defense, it seemed to become much more interesting.

As long as Ning Zhe's ancient and unwavering voice is filtered out, the whole person becomes energetic.

When she wanted to share this discovery with Lu Xiaoya beside her, she found that the two most important women around Ning Zi had already fallen asleep. This made Zhai Qiuxian suddenly envious of Lu Xiaoya. If nothing else, if you find a man like Ning Zi, you can at least not have insomnia at night, right?

…

"...Please note here that in equation (3), I assume the smooth divisor D∈|-λKM| and h is the smooth Hermitian metric with curvature λω0 on the line bundle-λKM..."

Standing on the podium, Ning Zi continued to explain the paper.

There is a story. Although Zhuo Mingqian couldn't understand the paper, his analysis was still very accurate.

The person he was talking about sitting on the far left was Fan Zhenhua, who was the defense secretary. He was here to help Ning Zhe. Although his research content overlapped with differential geometry, it could be said that it had nothing to do with Ning Zhe's thesis. It's not relevant, so naturally I don't bother to participate in the discussion, let alone take notes.

But then again, it's not that he didn't understand it at all, nor did he find it very boring. On the contrary, Fan Zhenhua actually listened very seriously. After all, some mathematical ideas are interlinked, so he can naturally find fun in it.

In this way, two hours passed in a flash.

Whether you're sleeping or really listening, time actually flies by.

When Ning Zi finished his report, the formal question session began.

However, this was obviously not a normal thesis defense, because the academicians’ questions quickly evolved into a discussion site, and the boundaries between the expert groups with opposing opinions began to become less clear.

"I think the curvature of the number of scratches is not uniformly bounded..."

"No, we should first consider the consistent boundedness of the relevant geometric quantities at finite non-zero moments..."

"But in the proof process of Theorem 3, I think the completeness condition was not taken into account, because the usual parabolic Schauder estimate cannot obtain a high-order consistent estimate near zero time."

"This is not good enough, Ning Zi, please explain the prerequisites to Lao Zheng..."

…

The sound was so loud that it disturbed the dreams of the two women in the last row...

"Ah, are you finished with your defense?"

"I'm answering..."

As soon as she raised her eyes, Lu Xiaoya saw Ning Ju and several old men starting to point out the situation. When she realized what she was doing, she suddenly felt a little embarrassed.

"Oops... I woke up too early in the morning and couldn't help but fall asleep."

"You're so sleepy, can't you be pregnant?" Ning Xiao, who had also just woken up, asked subconsciously.

"Oh, how is that possible? We agreed not to have a baby until after graduation."

"Ph.D. applicants please leave with everyone else. The defense committee will enter the review process..."

"Is this the end?"

"Not yet, but it's coming soon. Anyway, it's just a formality. Hey, you see, the boss is the boss. If I can have this card in my defense in the future... tsk tsk tsk..."

"Well, there are also academicians who specialize in sports science?"

"Ahem, actually biology is similar..."

"Hey, I feel like there's something wrong with Ning Zi's state. He looks troubled. Is there something wrong with his defense?" Lu Xiaoya said suddenly.
