The end of technology.

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.

Chapter 176 The Subversive Hypothesis

"Will Ning Zi be troubled?"

While Zhuo Mingqian was still confused, Lu Xiaoya had already nimbly slipped out through the back door.

In fact, Zhuo Mingqian wanted to explain to Lu Xiaoya that Ning Zi's doctoral dissertation defense was actually a process. Didn't even Principal Chen sit down and watch?

Those old academicians might not quite understand what Ning Zi was studying.

Moreover, the academicians were obviously at a disadvantage during the discussion.Before Ning Zi could answer many questions, internal debates began.

From the perspective of Zhuo Mingqian who had consciously participated in many doctoral dissertation defenses, Ning Zi's performance today was perfect.Although he couldn't understand, he never let go of his ability to observe words and expressions.Just looking at Mentor Ning Zi's expression, one can see that there is no surprise.

But he dare not say that he knows Ning Zi better than Lu Xiaoya.After all, two people sleep together every day.

When Lu Xiaoya jumped out, Ning Xiao and Di Qiuxian also followed out of the lecture hall, and Zhuo Mingqian naturally trotted out to follow.

Many people have gathered in the corridor outside the lecture hall.

There are still quite a lot of people who came to observe Dr. Ning Zi's graduation defense this time, and they are mainly graduate students from Huaqing University and Yanbei University.However, today's doctoral defense requires an electronic pass after the online application is reviewed, so this situation is expected.

Ning Yuan has already arranged staff, and is orderly inviting these auditing graduate students to other conference rooms and lecture halls on the fifth floor for discussion, so although there are many people, it is not chaotic.Zhuo Mingqian also saw at a glance that Ning Zi was chatting with someone at the main entrance, while Lu Xiaoya was standing aside.

Judging by Ning Zi's expression, it is indeed quite serious.

Just as Zhuo Mingqian was about to go over, he saw Ning Zi waving to him, and he quickened his pace.

"I have something to do. It may take about an hour. The defense committee will eat first when the results of the meeting are out. You don't have to wait for me. You can entertain me."

"Ah? What's so important? Today is the graduation defense, you don't wait for the result? When the bosses ask, what should I say?"

Zhuo Mingqian was stunned and asked immediately.

"Well, you just said that the question asked by Academician Yuan just now gave me some inspiration, and I'm going to check some information."

"There seems to be no problem in the defense. I think you answered well."

"It's not a question for answering. It's just that the question about disturbance just now made me think of a possibility. We usually think that four-dimensional or higher-dimensional dimensional space will maintain a relatively stable state in real time. The disturbance control total of overlapping dimensions It is ordered and obeys the basic rules of physics, such as energy conservation. But if two different dimensional spaces overlap, if the rules are contrary, it may not be a stable space, but will continue to expand, just like... …it’s like… the singularity of the universe. Um, so you get it?”

Zhuo Mingqian shook his head blankly.

"Well, it's right if you don't understand. Anyway, I will leave it to you first. I will be back before two o'clock in the afternoon. After lunch at noon, you can arrange for the academicians to have a rest. By the way, Xiaoya, cousin, I will come back at noon. I won’t be with you guys anymore. Let’s celebrate in the evening, if you have anything to do, go directly to Xiaozhuo, or let Xiaoya go to Director Jin, and they will make arrangements.”

"No problem, just do you want to help?" Lu Xiaoya raised her head and asked.

This question made Ning Zi smile happily, stretched out his hand to pinch Lu Xiaoya's flamboyant little face, and said, "You are not interested in these things, I will tell you about them at night so that you can sleep more soundly. "

"Oh..." Lu Xiaoya was a little embarrassed, after all, she really fell asleep just now, but who made her wake up so early today?

"Okay, Ning Zi, you go first, you don't have to worry about us, we can take good care of you."

"Well, ask Professor Fang to have dinner with me tonight."

"it is good."

After saying hello, Ning Zi nodded to Zhai Qiuxian again, then turned around and left directly.

……

"What did Ning Zi say just now?"

"Time? Space? Low-dimensional and high-dimensional? Let me tell you, these things are not comprehensible to normal people. If you want to understand them, you must understand a bunch of symbols. Really, last time I read Ning Zi's handwriting It’s only when you read those manuscripts that you know that there are too many symbols in mathematics, and all of them are very weird, so let’s not worry about it. As long as there are no problems in the defense, it’s fine.”

Lu Xiaoya said carelessly.

She is very open-minded, and has already given up treatment.

At present, the biggest problem of marrying Ning Zi is that everyone has the same brain, but they always feel that their brains are not enough.

In the end, I can only lament that all the nutrients I eat grow muscles.But for Lu Xiaoya, this kind of trouble is actually not a particularly bad thing, because she can always quickly adjust her mentality and focus on other places.

For example, after marrying Ning Zi, she can freely come to Ning Yuan every day to enjoy the chef's elaborate food with peace of mind. This alone can make her feel happy from the bottom of her heart.

"Xiaoya, does he often do this?" Zhai Qiuxian asked suddenly.

Lu Xiaoya tilted her head and thought for a while, then shook her head blankly, and said, "Not often, right? Normally, he seldom has something to do, so it's not like that."

"Oh, looking at Ning Zi's serious look, maybe there will be some breakthroughs, and there won't be another major event going to happen?"

"Haha, Ning Zi is not omnipotent. Besides, if something big happens, it's none of our business. Let me take you to the kitchen to see if Master Su is here today. If he is, we will be lucky. Master Su The cooked food is really delicious. Brother Zhuo, let's go first."

After finishing speaking, Lu Xiaoya happily led the two women towards the elevator. In fact, Zhuo Mingqian also wanted to follow, but Ning Zi also arranged a task for him, so he had to give up.

He is so difficult.

……

At this time Ning Zi had already walked out of Ning Yuan and returned to the study of the small villa.

After entering the door, he saw Sanyue pacing in the room.

As soon as he entered the door, Ning Zi said: "Wrong theoretical guidance may also lead to correct results. For example, Carnot's theorem is obtained through the reasoning of caloric mass theory, and caloric mass theory has been abandoned by the theoretical circle. Therefore, when the medium space research, relying on the exhaustive method?"

"Meow..." the kitten let out a cry, and then jumped into Ning Zi's arms.

"It can be said that it is just a lucky exhaustive method. The specific principle is to modify the response of microscopic particles by continuously modifying the frequency, and then track the particle transition through traceable specific values, collect data and model. But at that time we There's an enormous amount of data. If your thinking is correct, it could take thousands of years to exhaust all scenarios if we're not lucky enough."

Obviously March has understood his thoughts, and the kitten understands him.

"It is known that you come from another universe. Each universe is connected to the interior by a medium space. The principle followed in the medium space is that the speed of particle motion is always greater than the speed of light. According to these conditions, the final modeling of the macrocosm is a lot The universe is in various stages, erupting, expanding, heat-dead, being squeezed by the surrounding universe, and then energy is injected into the medium space, and the universe starts to shrink... But what if it is wrong?

Let us first assume that the theory of relativity is absolutely correct, then calculate according to my idea, if there is such a hypothetical circular high-dimensional space, then according to the calculation of the theory of relativity, it should not be a regular sphere, or a singularity, its The interior may be hollow, as if there is a sandwich between the universes.So the physical law in the medium space is not that particles are always greater than the speed of light, but that the speed of light is slowed down when passing through the interlayer.

This formula should be deducible. With this formula, we can directly calculate the curvature and position of the space, and position the space through experiments.But this needs to revise Ning's inequality, k is not the only constant, it should depend on the position of the light spot when it passes through the magnetic field.If accurate calculations can be made, theoretically the medium space can be deduced with precise coordinates outside the space.It is not a subway station, but a huge energy storage. "

Ning Zi was talking eloquently, and a picture of the beginning of the birth of the universe had already appeared in his mind.Different dimensions are intertwined to construct a huge, complex and disordered system. Under the action of rules, the originally chaotic and disordered state gradually began to become orderly.Galaxies began to form, and countless planets began to perform their duties in an orderly manner, rotating under the force.

This sounds contrary to the theory of entropy increase, because from disorder to order requires an injection of energy.Otherwise, a closed system will only become more and more chaotic.So there is only one reason for all this. During the expansion period of the universe, energy has been injected to ensure that the direction of the planet becomes more orderly.

The theoretical library in March before believed that the projection of the medium space on the universe corresponds to the undiscovered dark matter, which affects the expansion of the universe.But now Ning Zi feels that this conclusion is open to question.

"Meow, I don't know, but I can do a preliminary verification of your idea. If your idea is correct, then take the Milky Way as an example. It is allowed to have giant celestial bodies in its central area, and there may even be two The connection point of high-dimensional space recursion. But according to the current astronomical theoretical model, the middle region of a large galaxy is a black hole with huge mass, and it is impossible to have any celestial bodies. In fact, no celestial bodies have been found in this region so far. "

Ning Zi nodded and said: "First of all, not finding it doesn't mean it doesn't exist. The current astronomical theoretical model may still be wrong. I didn't find it before because everyone didn't think in this direction. If you don't look for it , How do you know if there is no? I think we should first construct this theoretical model, and then start calculations to find out where these celestial bodies may exist. As for the verification work, that is what astronomers should be responsible for, right?"

"Meow, of course. If this is proved, then our plan should be advanced. This means that human civilization can travel the entire universe at a faster speed, and even transform the planet by guiding the energy of the medium space. Adjusting the livable environment of the planet is indeed a genius idea. Then the next step is paper writing and huge calculation work. But I need you to record the entire derivation process in detail first."

Ning Zi nodded and said: "This is also the reason why I chose to come back at noon. I need to finish the paper as soon as possible, and then hand it over to those astronomers for verification. It is exciting to think about it. A three-dimensional line can theoretically completely cut all three-dimensional, four-dimensional or even higher-dimensional structures, even black holes, the structure of space is so wonderful."

"Meow……"

……

It was exactly two o'clock in the afternoon when Ning Zi returned to the doctoral defense point.

There is actually nothing to say about the next agenda, and there are many fewer people watching.

For the members of the defense committee, Ning Zi's sudden departure in the morning may seem a bit shocking, but with Zhuo Mingqian's hard-working explanation, it is actually not that unacceptable.

In Zhuo Mingqian's words, Ning Zi was inspired by the mentors, and suddenly came to the inspiration, and rushed to record the inspiration, which is naturally understandable.

Mathematicians are probably the group of people who believe in inspiration or epiphany more than writers.

There are countless examples of people who have studied a topic for many years and got stuck on a certain problem for months or even years, but suddenly one day, as if they were enlightened, they figured out this key node.

The trigger point may be a casual remark, a question posed by others, a lonely afternoon, or even a fallen leaf, which makes no sense at all.

Most of the mathematicians who have reached the position of academician, in particular, have had this kind of epiphany experience.When the inspiration comes, the problems in front of me are solved naturally, and the achievement is supreme glory.The only problem is probably that this kind of inspiration is uncontrollable, no one knows if it will come, or when it will come.

So the only thing mathematicians can do is to quickly record what they think about at that moment when inspiration comes.

Not to mention that it can bring inspiration to a young mathematician like Ning Zi who is almost all-rounder. In fact, it is something that can be used to brag. It is also honorable to mention the source of inspiration by the way.

Coupled with the big body, there is no neglect here.

Although Ning Zi did not come, the mentor Chen Lixiang and the principal Chen Yonggang also accompanied the whole process, as well as world-class experts such as Dominion Duncan and Conan Lamar, and the standard was high enough.

So Ning Zi successfully passed the thesis defense as Zhuo Mingqian expected.

In theory, it can already be called Dr. Ning.

However, before Ning Zi officially received his doctoral diploma, Chen Yonggang announced a news at the end of the report meeting.

"I announce the official appointment of Dr. Ning Zi as a tenured professor of the University of Physical Education and the title of first-level full professor."

So after Chen Yonggang said these words, he could directly bypass Dr. Ning and call him Professor Ning.

This did not exceed the expectations of many people at the scene, as if the doctoral dissertation defense was a formality, giving everyone a step down.

Sooner or later, the title of first-level full professor will be given, just like academician will definitely be awarded.

It's just somewhat embarrassing.

After all, it may take others most of their lives to complete the journey, but this guy did it in his 20s.

Zhuo Mingqian even suspected that the school was paving the way for Ning Zi to become an academician next year. After all, if Ning Zi was added as an academician next year, it would be somewhat unpleasant if he was not a first-level professor.

Moreover, academicians are elected every two years, and each election takes about ten months from nomination to finalization of the list.

I started teaching in December this year, just after the end of the Chinese New Year and in February, the nomination of new academicians will start, and this time next year will be about the time when the list of additional academicians will be announced to the public. Zhuo Mingqian can only feel amazed at the timing of this time.

As for the nomination of new academicians, three academicians are required to write a report, which is not a problem for Ning Zi at all.

Not to mention Fan Zhenhua, Lu Zhengyue and Lu Zhengyue would be brainless to help Ning Zi write a recommendation letter, and eight academicians came just after watching a thesis defense, not to mention that Ning Yuan also recruited several academicians this time... Thinking of this, Zhuo Mingqian envied him She glanced at Chen Lixiang, who was standing beside Ning Zi and smiling like a flower blooming.

The student is already a first-level full professor, how long will it take for the tutor to become a full professor?

When next year the students will all be academicians, is it still far away for the supervisor to become an academician?

A real winner in life.

……

Just when Zhuo Mingqian was full of emotions, March had already sent a new paper signed by Ning Zi to the submission system of the world-renowned scientific journal "Science".

This is a multi-level paper covering mathematics, physics, and astronomy.

It took a total of five hours and three minutes from the proposal of the idea to the completion of the thesis.
