Chapter 975

Tiktok,

, woke up early as usual. He didn't study for too long last night. All of this must be blamed on the silly girl who was pregnant. She didn't know why she was so mad that she wanted to coax her, perhaps what she had seen in the emotional story of shaking.

Glancing at Xiaoman lying beside him, Xu mang looks at her quietly, saying that he seems to have not seen Xiaoman closely for a long time. In high school, he often can see Xiaoman face to face closely, and then he seldom has such a chance.

Don't mention...

Xiaoman is really beautiful, but even if she is as beautiful as a fairy in the sky, she is still pregnant and becomes a mother to be.

At this time,

Xiaoman suddenly woke up and stretched out his waist lazily. Seeing that Xu mangzheng was staring at himself, his pretty face was slightly flushed with rosy clouds, and he said with shame: "what's the matter? I've been together for so long with this kind of eyes. Is it necessary?"

"Eh?"

"It's just that I haven't seen you like that for a long time." Even if it is rebellious, this moment will become tender, stretch out his hand and pinch the goblin's face, saying: "before... How never thought that I would get married so early and become a father so early."

"Well!"

Yang Xiaoman was close to him, and then his whole body was attached to Xu Mang's arms. He said gently, "me too... My mother used to say that I want to be a nun in the future. As a result, things are changeable. I even got married before others, and even had children."

"Since I took you home to meet my parents, my parents smile a lot more than before, and now I'm pregnant again... They are more happy." Are you all saying, "is destiny stupid?"

"Maybe..."

"but we Chinese people do not believe in fate." Xu mang said with a smile: "most people are fighting against fate."

"Eh?"

"But I read from a magazine that statistically... People born at the bottom of society, even when they are adults, the unhappy experience in their childhood will make them form a very big cognitive defect, and their taste and moral standards will be incompatible with the high society." Yang Xiaoman said.

"Well!"

"This is only a foreign phenomenon, but it can not be verified in our country." Xu mang quietly reached into the quilt, touched Xiaoman's stomach... Felt the feeling of life in it, and seriously said: "we have essential differences in education."

"The difference?"

"What's the difference?" "Elite education?" Yang asked? I remember the "grey man theory" of Oxford University, which seems to be the case

Xu mang nodded his head and said calmly: "the grey man theory indicates in detail that if he is an ordinary person, his qualification is very ordinary, and if he works very hard, this kind of person is the most pathetic person in the world, which is called grey man by Oxford."

"Yes

"I've heard about it, too." "I particularly dislike the so-called grey man theory," Yang said

"So..."

"we will return to the previous theory again." Xu mang showed a smile: "it is impossible to separate personal ideal and national destiny... Because as long as you are in China, as long as you are willing to work hard, love to study and dare to work hard, you can walk all the way from a backward village to the University of Beijing in Qing Dynasty."

At this time,

Xu mang then said: "the classes in China have always been interlinked. From a historical point of view, this is a truth, such as the situation of your family... If you go up three generations, it must be a peasant background, and have you found that..."

"in China, even if a person has more money, if he pretends to be a foreign aristocrat, he is very ungrounded A strong sense of superiority, he will be scolded to death by us. " "Even in myth... We have a gap with foreign countries," Xu said with a smile

"In foreign myths, what kind of flood punishes human beings? Human beings can only kneel down and pray for forgiveness, but here in us... It has always been Hou Yi shooting the sun and Jingwei filling the sea. We have worshipped warriors who have changed their lives against the heaven since ancient times." Xu mang takes out another hand and pinches Xiaoman's cheek.

"It is no exaggeration to say that most of the people living in this land have the courage to never compromise in the face of fate, which is incomparable to any country in the world." Xu mang said: "so..."

at this point,

Xu mang suddenly stopped and looked at the grinding goblin with a smile.

"So what?" Yang Xiaoman tooted his small mouth and said in a huff: "don't sell the key, say it quickly!"

"So you and I can come together, not so-called fate intertwined, but to strive for their own happiness." "This is what we strive for by ourselves, not a gift from heaven. We don't need happiness. We owe it to fate," Xu said

In fact,

there is another meaning in Xu Mang's words. He read the micro blog quietly yesterday and found that many people were misled by the well-known big V's. He really believed in their theory and thought that China is not good, nothing can be done.It's interesting to think about it...

"husband!"

"You're right Yang Xiaoman was so excited that he put his arm around Xu Mang's neck, and then got close to it. He almost didn't give Xu mang a kiss.

Before,

Xiaoman always thought that this was the arrangement of fate, so that two people who had nothing to do with each other finally came together, but... Now suddenly, I feel that this is clearly the happiness that he has won. Why should I owe it to fate?

Tired of crooked for an hour, Yang Xiaoman suddenly asked: "when to go back?"

"Tomorrow afternoon." Xu mang said: "I'm not in a hurry for this moment anyway. I'll solve the zone conjecture and I'll be able to solve it tonight."

"Ah?"

"So fast?" Yang Xiaoman was stunned for a moment, surprised to say: "last night you... You did not have how to solve the problem."

"..."

"it's not because of you!" Xu mang said angrily: "apply for three hours this evening... Don't disturb me, let me solve the problem wholeheartedly, by the way... Ferrari announced their next flagship sports car, can I buy two?"

Yang Xiaoman frowned. In fact, she was not distressed by money. She was just upset by Xu Mang's extravagant spending. He undoubtedly made a bad impression on the children, believing that the family was particularly rich.

Although it's really rich, the child should instill the concept of family poverty from childhood, so that he has a spirit of constantly striving for improvement. Otherwise, he can learn from his father... He needs a sports car when he opens his mouth, and he wants an airplane when he shows up?

"No way!"

"Only one!" Yang Xiaoman resolutely refused Xu Mang's request and seriously said: "you have to change your bad habits... Later let the children see their father is like this, will be sad, why such an excellent mother married a waste father."

Xu Mang:???

In the evening,

at night,

Xu mang sat alone in his room and began to work. Now he has solved the problem of covering any convex body with a long strip, that is to say, Xu mang has proved that the total width of the strip covering the convex body is at least the width of the convex body itself, that is, the minimum width of a single strip that can cover a convex body.

However, we still need to think from another angle, covering a unit sphere with a certain type of ball belt... Specifically, each belt is the intersection of a sphere and a specific three-dimensional slab, where the strip is a space area symmetrically sandwiched between two parallel planes about the center of the sphere.

Instead of slats,

but defined in the metric space of geodesic sphere.

After studying for half an hour, Xu mang knew that if we could solve the problem, we must find the minimum width sum on the belt which can cover the unit sphere. Therefore, the width measurement method is different from that before. It is defined as the length of the arc, not the Euclidean distance between parallel lines or surfaces.

"That's it..." Xu mang breathed a long breath, and the stone on his heart fell down. He quickly searched for some information with his mobile phone. In a certain paper, he proved a very useful point of view, and Xu mang tried to find the contradiction through the method of absurdity.

That is to find a point on the sphere, but not in any of these belts.

"Is that so?"

"It seems so!" Xu mang looked at the content he wrote. It seems that zone guess is not so difficult, but it is very complicated in argument. It is natural to solve this problem in ten years.

However,

however, Xu mang showed a smile. He felt that the other party was too arrogant to speak. How dare he jump out at such a speed? I don't know the height of the earth.

However, there is a saying that this zone conjecture is very interesting. After all, it can attract the attention of mathematicians in the field of discrete geometry for more than 40 years. We can imagine how important it is to reality. Besides discrete geometry, it can also be promoted in high-dimensional space.

Even in physics and cosmology, there will be unspeakable ascension.

At the same time,

at the same time,

Yang Xiaoman was staring at the silent TV with his eyes blankly, full of pictures of beating Xu Mang, and secretly took a look at Xu mang who was working.

"Hum!"

"I'm angry!" Yang Xiaoman suddenly yelled.

Xu was almost scared to death by her face

"Big fool!"

"Do you know I'm... Bored now?" Yang Xiaoman a white eye, seriously said: "talk to me!"

"..."

"no time!" Xu mang frowned and said, "wait for me another hour, remember not to make trouble!"

Later,

Xiaoman watched her husband turn his head again and was working quietly. Maybe Xu Mang's voice was a little heavy just now, which made the angry little woman realize that she was wrong, but even if she was wrong, she could not admit it."Angry to angry... I don't love you anymore." Yang Xiaoman got up and sat at the head of the bed, with his back to Xu Mang, talking to himself, but her voice was a little loud: "speak well, coax my heart soon!"

(￢_ ￢) sneaking a glance...

as a result,

Xu mang did not respond.

"Alas..."

"I have to run away from home!" All of a sudden, Yang Xiaoman, who was the playwright, stood up angrily, took a piece of clothes and put it on his body. However, he said, "it's so cold outside... I have to put on my clothes, or I will be frozen to death."

Words and expressions,

(￢_ ￢) peek again...

the result is still no response.

What's the situation?

Why didn't the pig's hooves react?

Yang Xiaoman: (~ ~)

slag man!

Scum man!

"Then I'll take another bowl... Take the bowl and ask for food." Yang Xiaoman looked for a bowl everywhere in the room, and didn't know how she found it. She found a broken bowl. At this time, Xiaoman with the bowl in his hand was a little at a loss.

"I'm going to beg!"

"I really went to beg!" Yang Xiaoman called out.

In the face of Xiaoman's performance, Xu Mang's heart is broken, but it is more of a kind of love. Unexpectedly, his wife has great talent for acting. It is clearly his own fault, but he tries to push the problem onto others.

It's so cute!

"Or...

" you take two bowls? " Xu mang said with a smile.

Seeing that Xu mang finally took care of himself, Xiaoman hurried to his side and said with a smile, "are you going to beg with me?"

"No!"

"Sponsor you to open a branch." Xu mang said with a smile.

The next second,

Yang Xiaoman threw the stainless steel bowl on the ground, grabbed Xu Mang's ear and said angrily, "my mother is not alive... I must kill you!"

"Ouch, ouch..."

Xu mang grabbed Xiaoman's hand and quickly begged for mercy: "don't go, can you stay? I beg you. "

Yang Xiaoman released his hand and said with a face of grievance: "then I can't help but promise you..."

Xu Mang: (° ー)

God!

After this pregnancy, I feel that Xiaoman's IQ is less than 30.

After that,

little Manyi attached to Xu Mang's arms, feeling the warmth of his man and watching him solve one problem after another. He was arrogant in his heart. Although this big fool is useless at the foot of the mountain, he just needs to love himself.

"What does that mean?" Yang Xiaoman asked.

"I constructed a special set of points in three-dimensional space so that at least one point was not in the area covered by the board." "If the whole set of points is located inside the ball, it is relatively easy to find another point on the sphere that is not covered by the board, that is, not covered by the ball belt."

"If any point in the set happens to be outside the sphere, you can replace several smaller belts with a larger one, which is the same width as the larger one." "This can reduce the number of ribbons in the initial problem without affecting the width and sum," Xu said

"Does that mean that some point on the sphere will be determined not to be in these belts?" he said seriously

"Ouch

Xu mang looked at Xiaoman's side face and said, "my beautiful girl is so smart? So beautiful and so smart, man... Can you leave some space for others? "

"Hate ~"

"you big fool!" Yang Xiaoman quietly twisted Xu Mang's thigh: "when is the end?"

"Soon..."

"it's not a big problem." Xu mang chuckled and said indifferently: "it has been solved now... But I want to shorten the process a little bit. The answer given by the genius of Dika to the whole world is too long. I think it can be shortened a little bit."

"And... Seems to extend another conjecture..." Xu continued: "another more basic conjecture about spherical coverage..."

Yang Xiaoman said angrily: "hello? Are you finished? It's almost OK... What extends another guess? I don't allow you to extend it! "

"Ouch..."

"in fact, I already know the answer... In my guess, the belt covering the sphere does not need central symmetry." Xu mang said with a smile: "but the paper is not enough, I don't want to write... Let them think about it by themselves."

For a moment,

Xu mang put down his pen in silence.

"Solved?"

"It's solved!""What... This is the conjecture that French mathematical genius took ten years to solve?" Yang Xiaoman looked disappointed and said, "so the gap between you is so big?"

One took ten years, the other took a few hours...

oh my God!

It turns out that it's this kind of person that big V boasts?
