The end of technology.

Chapter 177 Doctoral Defense
New term, new atmosphere.

The campus of the University of Physical Education with many departments has become more lively.

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

During the principal's speech, Chen Yonggang shouted the slogan "This century has officially entered the world, the development of science in the world depends on China, and the development of China depends on the big body!" at the conference.This probably also represents that the official of the University officially began to support Ning Zi's speech at the Freshman Conference last year as a freshman representative.

This video was also quickly spread on the Internet.

Netizens with good deeds tweeted about almost all the 985 colleges and universities in Huaxia. There are always those who like to watch the excitement. They hope to see the reaction from the most powerful schools in Huaxia, and then just eat melon seeds while eating melon .

However, this time it was obviously a miscalculation, and the matter could not be provoked after all, because no one took over.

Shuangdan University updated its Weibo on the same day, quoting the original text of "Peach Blossom Fan Lingering Rhyme Leaving the Pavilion Banquet with Rest and Pai Sha": "Seeing the dawn of the jade palace in Jinling and the early blooming of the Qinhuai water pavilion, who knew it would be easy to disappear... ...I used to sleep on this pile of moss and blue tiles; I have seen the rise and fall of 50 years; the bird clothes alley is not surnamed Wang, the ghosts of Mochou Lake cry at night, and the owls live in Phoenix Terrace. The dream of the residual mountain is the most real, and the old environment is lost Difficult to fall."

Excited netizens immediately began to popularize science with everyone in the comment area. The ellipsis part is the famous "Seeing him getting up from Zhulou, seeing him entertaining guests, seeing his building collapsed!"

It's a pity that after netizens popularized science in the comment area, the editor of Shuangdan University's microblog deleted this microblog from the heart.

Although a lot of pictures have been intercepted, if they are deleted, they are deleted. The imaginary Internet war of words has not been fought after all, which will make many people feel regretful.But it doesn't matter, naturally there are jokes who mobilize collectively, and after all, it makes the Internet a lot more lively.

Stories such as the rise of physical education teachers finally became popular on the Internet.

However, Internet hotspots come and go quickly after all.

Not to mention that there are many strange things happening every day. Many idols in Huaxia have broken their hearts because of hot searches on the Internet, and they have never been stingy in coming forward to attract the attention of the public.Even if you have to apologize afterwards for taking up public space...

So after several well-known idols made all kinds of moths, 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 that 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 as if everyone thinks the chip is very important when it is restricted, but once the restriction is lifted, few people will pay attention to the chip anymore.

At least before there are computers and mobile phones in normal use, how many people will really pay attention to whether Huaxia can make chips every day?

Not important, not at all.

For the vast majority of people, as long as it does not affect their daily life, no one will devote too much energy to pay attention to these things.

It’s nothing more than seeing it and making a few complaints. 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 popularize these things with everyone on the Internet.

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

Let a chip engineer go online to talk about the impact of quantum physics on chip development, and there is a high probability that he will end up in the dilemma of talking with a duck.

The unbalanced development of human intelligence determines that in this world, one percent of people always determine the development direction of civilization, and the remaining 90.00% of people follow the times and move forward ignorantly.Life is less than a hundred years, as long as you don't think about the past and think about the future, what you care about is the content that is relatively close to life after all.

Celebrity gossip is more interesting than science after all. Everyone can eat celebrity melons, but science is something that not everyone can participate in the discussion.Even substances that are replaced by scientific terms may be incomprehensible, and the names of the ubiquitous necessities of life activities that are replaced by academic names will make people feel less calm.

For example, a solution made of 0.9% hydrohydroxy acid plus sodium chloride, many people think it is not a good thing when they hear it, but if they talk about normal saline, they probably think it is pretty good.

This is probably the status quo.

Therefore, when the principals 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 a small-scale discussion.

……

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

The banners played are not the same. Whether it is inspecting laboratories in China or production bases, these superficial excuses are all very good.

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

Basically, when people come, they will naturally be received by officials.

The chip research center built by Apple for the University of Physical Education is naturally a must-see.

Ning Zi also met many bigwigs in the lab. As he said before, he is not responsible for discussing business issues with these bigwigs.

Basically, people are here. If the other party asks to visit the university or Ning Zi, then we will meet in the laboratory and greet each other. Then Ning Zi will treat the guests to a meal and give them a gift A small gift, the gift is a chip made by the latest technology in the laboratory, a radio frequency chip that has been advanced from 160nm to 75nm.

In fact, it is not worth much, but considering that the previous two first-generation 160nm industrial-made narrowband chips can be sold for a high price of 3000 million US dollars, the chips given away this time have higher technical content and higher natural value, at least indirectly helping these Internet companies. Big guy saved hundreds of millions of dollars.

It is enough to show how generous and generous the body 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'm just a pure student and I don't understand anything. When talking about cooperation and business, there are special people to connect with. If you want to talk about technology, you can chat .”

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

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

After bidding farewell to these tedious routine work, under the intense discussion of the group meeting at least three times a week, Chen Lixiang almost understood Ning Zi's graduation thesis.In the winter of 2018, when the semiconductor dispute came to an end, the date and venue of Ning Zi's doctoral dissertation defense have also been confirmed, and it will be held in Ningyuan on Christmas Eve.

……

Monday, December 2018, 12, at Yanbei University of Physical Education.

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

Especially for young people who are in love, today is the day of dating again.

In many cases, it is indeed impossible to say that Chinese young people worship foreigners and always like to celebrate foreign festivals.It is mainly the traditional Chinese festivals, most of which are themed on family reunion, and they are more serious. There are not many festivals that are really suitable for young people to go out and celebrate.

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 family reunion. Even if it is Qingming Festival-it is best for the whole family to go out to worship the ancestors to make the reunion more thorough.

It’s just one Chinese Valentine’s Day, and it sounds good with the romantic theme of magpie bridge meeting, but it’s not a holiday, no one reminds it, and it’s easy to forget. Although it has been hyped by businesses for many years, it hasn’t caused any big hits. festive mood.

However, it was finally determined that it was not Ning Zi's idea to defend the thesis on Christmas Eve. The main thing was to use the time of some academic leaders to participate in this defense.

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

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 chairman of the defense, Lu Zhengyue, the secretary of the defense, Fan Zhenhua, besides Su Zhiming and Shi Fushen, the expert judges included Ruan Zhiju, Zheng Yansi, Hu Zhizhen, and Yuan Jingheng.

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

The only one who is relatively young, Yuan Jingheng, is 46 years old this year, and he has just solved a world problem in complex differential geometry.

One can imagine how high the standard of Ning Zi's doctoral thesis defense is.

And today is his doctoral dissertation defense session. There is no one else, so he has one day for this defense alone.

Therefore, Chen Ideal informed Ning Zi early on that his defense process was also different from other doctoral students. Since his thesis was a relatively new topic, the report time could be extended to 120 minutes.You should know that for the general doctoral dissertation defense, the reporting time for doctoral applications is generally controlled within 40 minutes.

Of course, this is something that can’t be helped. After all, Ning Zi’s graduation thesis is more than 70 pages long, and both he and the reviewers think that there are not many places that can be saved. If you really want to control the presentation within 40 minutes, you can only go through the process quickly After going through it again, there are not many memory points left for discussion.

Anyway, today is a one-person thesis defense, and Ning Zi was directly given two hours to play.So the start time was relatively early, and the thesis defense officially started at [-]:[-] in the morning. As for when it would be completed, Chen Lixiang didn't mention it, and Ning Zi didn't ask either.After all, there is no case of failure, so naturally it is impossible to be nervous.

Ning Zi got up from the bed at [-]:[-] in the morning as usual.

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

After washing up, she urged Ning Zi to change into the formal suit she went to pick out with the two sisters of the Ning family yesterday - a set of expensive brand-name Chinese tunic suits.

After all, the doctoral dissertation defense must be videotaped.

And it is said that many masters and doctoral students from Huaqing and Yanbei have applied to audit Ning Zi's doctoral thesis defense.Of course, this is also normal, after all, it is a rare opportunity to be in the same room with eight academicians of Huaxia Mathematics Institute and two future associate academicians.

No one doubts that Ning Zi can be admitted to the academician, as for Chen Ideal... Ning Zi can be admitted, there is no reason why the tutor can't be admitted in the future.

After all, it was Ning Zi's chosen mentor.

Lu Xiaoya also plans to participate in this defense, not only her, 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 wait for Lu Xiaoya, he had to go to Ning Yuan to do some reception work.

……

At 55:507 in the morning, Lu Xiaoya, Ning Xiao, and Zhai Qiuxian walked into Lecture Hall [-] of Ningyuan Building through the back door almost stuck.

This is also the place where Ning Zi's graduation defense is held today.

There are not many seats left in the medium-sized lecture hall that can accommodate 120 people in total.

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

"Xiaoya, this way."

It was Zhuo Mingqian who spoke. He actually returned to the capital from the west of Nanhu Lake where he was teaching during the summer vacation, but at that time Ning Zi was still on his honeymoon and had no time to talk to him.

After the semester started, he was arranged to go to Ningyuan to do some administrative work with the chip research and development center, learn management experience, and prepare his doctoral dissertation by the way.Now waiting for the official listing of the [-]-mu research base of the University, he will be responsible for the coordination and management of various laboratories.

Hanging the signboard of Ningyuan staff, it is natural to help the three of them occupy a good position early.

"Brother Zhuo, good morning." Lu Xiaoya brought the two of them over with Sanyue in her arms, and greeted Zhuo Mingqian.

"Hey, good morning, Ning Xiao, and this beauty, it's early too!" Zhuo Mingqian quickly glanced at Ning Zi, who was surrounded by a group of old academicians in front of the lecture hall, and smiled brightly with the three The beauties greeted each other.

Although he had chased after Ning Xiao before, and now Ning Xiao is engaged and her husband is also sitting in front, but with Zhuo Mingqian's temperament, he obviously wouldn't feel embarrassed by the things that didn't happen in time in the past.

Ning Xiao also has a hearty personality, not to mention that the two have never been in love, even if they really did, they let go of it after such a long time, and waved at Zhuo Mingqian generously, and then sat down with Lu Xiaoya Beside him, only Zhai Qiuxian maintained his usual cold temper, completely ignoring 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 beside Zhuo Mingqian.

"Hey, beauty, let me introduce myself. My name is Zhuo Mingqian. I have a Ph.D. in sports science from the University of Physical Education. You have such a good figure, so you must exercise regularly, right? You can consult me ​​about how to train scientifically. I am unmarried, even I don't have any girlfriends, so don't be afraid to disturb me at any time, let alone be afraid of misunderstanding."

Apparently, the one-year coaching experience has not completely polished off the edges and corners of this person, and he is still so familiar.

It's just that this time it was obvious that there was a snag, and Zhai Qiuxian just glanced at Zhuo Mingqian before turning his gaze to the front of the lecture hall.

"puff……"

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

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

"Zhai Qiuxian, this name is good, the person lives up to his name, Sui and Liu have gone through many autumns, and Yan sings opera Yaoxian..."

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

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

Speaking again, this is really disrespectful to Ning Zi.

……

"...In this paper, I will conduct a targeted study on a kind of Keller-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 combination with the wisted Kahler-Ricci flow.Using the smooth approximation of the twisted Keller-Rich flow to obtain the existence of the long-term solution of the cone-singular Keller-Rich flow, and then through the appropriate improvement of the Perelman estimation in the case of the smooth Keller-Rich flow, discuss the Fano manifold The Convergence of Conic Singular Keller-Rich Flows. "

When the chairman of the defense finished introducing the agenda, Ning Zi stepped onto the rostrum and began to make a report.

Obviously, for students who are not majors in mathematics, these contents are lengthy and boring, and this report is probably no different from a heavenly book.

For example, Lu Xiaoya, for the first 10 minutes, she was able to secretly take a picture of the rostrum with her mobile phone with great interest. After 10 minutes, she was already sitting in her seat and yawning, and her upper and lower eyelids obviously started to fight. Even a slight snoring sound is not surprising after a while.

Cousin Ning Xiao was not much better either, she also looked like she was about to fall asleep.Zhai Qiuxian is very energetic, but her attention has obviously begun to slacken...

Of the group of four in the last row of the lecture hall, Zhuo Mingqian was probably the only one who listened with gusto.

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

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

"Then you can still listen so seriously?"

"You don't understand that, do you?"

Zhuo Mingqian suppressed his voice, turned his head slightly, and said softly in Zhai Qiuxian's ear: "Don't listen to what Ning Zi said, you can look at those old men in the first row, they are all academicians, although you can't see them expressions, but you can carefully observe their movements, such as the one on the far left, I’m wondering if he didn’t understand. Do you suddenly feel that you’re not so stupid anymore?”

"Oh why?"

"Look at other academicians, from time to time they will whisper and discuss a few sentences, the third from the left, and occasionally take notes with a pen, but look at him, his posture has not changed until now... To tell you the truth, I have a group meeting When listening to other senior brothers talking about the heavenly scriptures, they were also in a daze like this.

The most important thing is that I tried it on the stage yesterday, and I can see clearly everywhere.So even though I don’t understand it, I still have to look a bit cultural…”

Zhai Qiuxian was speechless after being analyzed by Zhuo Mingqian's words.

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

As long as Ning Zi's quiet voice from the ancient well was filtered out, the whole person would be refreshed.

When she wanted to share this discovery with Lu Xiaoya beside her, she found that the two most important women around Ning Zi were already asleep.This made Zhai Qiuxian suddenly envious of Lu Xiaoya.Not to mention anything else, if you find a man like Ning Zi, at least you won't suffer from insomnia at night, right?

……

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

Ning Zi, who was standing on the rostrum, continued to explain the thesis.

There is one thing to say, although Zhuo Mingqian could not understand the paper, but 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, and he was here to help Ning Zi hold the stage. Although his research content also overlaps with differential geometry, it can be said that it has nothing to do with Ning Zi's thesis. It is relevant, so naturally I am too lazy to participate in the discussion, let alone take notes.

But then again, it wasn't that he couldn't understand it completely, nor would 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 it is sleeping or really listening to it, time can actually pass quite quickly.

When Ning Zi finished the report, the formal questioning session began.

But obviously this is not a normal dissertation defense, because the academicians' questions quickly turned into a discussion scene, and the boundaries of the expert group who held opposing opinions began to become less obvious.

"I don't think the flex quantity curvature is uniformly bounded..."

"No, the uniform boundedness of the relevant geometric quantities at finite non-zero moments should be considered first..."

"However, in the process of proving theorem 3, I think that the completeness condition is not considered, because the usual parabolic Schauder estimation cannot obtain a high-order consistent estimation near zero time."

"This is not level, Ning Zi, explain the prerequisites to Lao Zheng..."

……

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

"Ah, are you done with your defense?"

"Arguing..."

As soon as she raised her eyes, Lu Xiaoya saw Ning Zi and the old men start pointing Jiang Shan, and when she realized it, she suddenly felt a little embarrassed.

"Oh... I woke up too early in the morning, I couldn't help but fell asleep."

"So lethargic, can't it be?" Ning Xiao, who also just woke up, asked subconsciously.

"Oh, how is it possible? We agreed to have a baby after graduation."

"Please leave the doctoral applicant with others, the defense committee will enter the deliberation stage..."

"This is the end?"

"Not yet, but it's coming soon. Anyway, it's just a formality. Hey, I've seen it, the big boss is the big boss, if I can have this card when I defend in the future... tsk tsk tsk..."

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

"Ahem, in fact, biology is also interlinked..."

"Hey, I feel that Ning Zi's state is a bit wrong. His expression seems to be troubled. Is there something wrong with the defense?" Lu Xiaoya said suddenly.
