Chapter 975: Xiaoman

　　 early morning,
Xu Mang woke up early as usual. Actually, he didn’t study it for too long last night. All of this is to blame on the pregnant silly lady, and I don’t know why suddenly... I had to coax her by myself as I went crazy. The emotional story of Douyin.
Glancing at the woman lying next to him, Xu Mang looked at her quietly, saying that it seemed that he hadn't looked at Xiaoman up close for a long time. In high school...but he could often see face to face up close, and then very There are few opportunities like this.
　　Don't even say...
　　 Xiaoman is indeed very beautiful, but even if it is as beautiful as a fairy in the sky, this is not... she is still pregnant and becoming a mother-to-be, the fairy will still be moved.
　　 At this time,
Xiaoman woke up suddenly, stretched out lazily, and saw Xu Mang looking at him intently. A red glow appeared on his pretty face, and he said shyly: "What's wrong... with this look Look at me, we have been together for so long, is this necessary?"
"Uh?"
"It's just been a long time since I have looked at you like this." Even if it's a long time ago, he will become tender at this moment. He stretched out his hand and squeezed the little fairy's face and said: "I...never thought I would be like this before. Get married early and become a father so early."
"Ok!"
Yang Xiaoman moved closer, and then his whole body clung to Xu Mang’s arms, and said softly: "Me too...my mother used to say that I am going to be a nun in the future, but...everything is impermanent. I got married before anyone else, and even got pregnant with a child."
"Since I brought you home to see your parents, my parents smiled a lot more than before, and now I am pregnant again...the two are happier." Yang Xiaoman continued, "Idiot...you said Is this all fate?"
"maybe..."
　　 "But we Chinese people don't believe in fate in our bones." Xu Mang smiled and said: "The vast majority of people are fighting fate."
"Uh?"
"But I have seen from a magazine, statistically speaking... Even if people born at the bottom of society become adults, the unhappy experience of childhood will cause them to form very big cognition defects. Taste and moral standards will be incompatible with upper class society." Yang Xiaoman said.
"Ok!"
"This is only a foreign phenomenon, but it cannot be verified when used in our country." Xu Mang quietly reached into the quilt and touched Xiaoman's belly... Feeling the feeling of life being bred inside, he said seriously: "We have a fundamental difference in education."
"the difference?"
　　 "What's the difference?" Yang Xiaoman asked: "Elite education? I remember Oxford University's ‘gray man theory’, it seems this is the case, right?"
Xu Mang nodded and said indifferently: "The Gray Man Theory specifies in detail that if an ordinary person has very ordinary aptitudes, and if he works very hard, this kind of person is the saddest person in the world and is called a gray man by Oxford. ."
"Correct!"
　　 "I've heard of it too." Yang Xiaoman said: "I particularly dislike the so-called gray man theory."
"and so..."
"Our topic is going back to the previous theory." Xu Mang showed a smile: "Personal ideals and national destiny are impossible to separate...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 a university like Tsing Hua University.
at this time,
Xu Mang continued: "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 look up three generations, it must be a peasant background, and do you have Find..."
"In China... even if a certain person is rich, if he pretends to be a foreign nobleman, he is very unearthed and has a strong sense of superiority, he will be scolded to death by us." Xu Mang laughed Said: "Even in the myth...we have a gap with foreign countries."
"In foreign myths, there are floods that punish humans. Humans can only kneel and pray for forgiveness. But here...Hou Yi always shoots the sun and fills the sea with fine guards. We have worshipped the gods since ancient times. A warrior of life." Xu Mang freed his other hand and squeezed Xiaoman's cheek.
"It is no exaggeration to say... Most people living on this land have the courage to face fate and never compromise in their bones. This is unmatched by any country in the world." Xu Mang said, "So ..."
　　The words are here,
　　 Xu Mang stopped suddenly and looked at the grinning little fairy with a smile.
　　 "So what?" Yang Xiaoman pouted his mouth, and said angrily: "Don't sell it, hurry up!"
"So I and you are able to come together, not the so-called entanglement of fate, but the happiness that we strive for." Xu Mang said: "This is our own struggle, not a gift from heaven, and happiness does not need to be attributed to fate. ."
　　 Actually,
There is another meaning in Xu Mang’s words. He quietly read Weibo yesterday and found that many people were biased by the well-known big Vs. He really believed their theory and thought that Hua Guo just couldn’t. Nothing can be done.
　　 It's interesting to think about it...
　　 "Husband!"
　　 "You're too right!" Yang Xiaoman was so excited, he hugged Xu Mang's neck directly, and then leaned forward. The fierce kiss... almost didn't give Xu Mang bald.
　　 before,
　　 Xiaoman has always felt that this is an arrangement of fate, so that the two people who have nothing to do with each other finally get together, but... now suddenly feel that this is the happiness that he has won, why is it attributed to fate?
　　 Greasy and crooked for an hour, Yang Xiaoman suddenly asked: "When will I go back?"
　　 "Tomorrow afternoon." Xu Mang said: "Anyway, I don't rush at this time. Once I solve the Zone conjecture, I can solve it tonight."
"what?"
　　 "So fast?" Yang Xiaoman was taken aback, and said in surprise: "You...you didn't solve the problem at all last night."
　　"..."
"It's not because of you!" Xu Mang said grimly, "Apply for three hours tonight...Don't bother me, let me solve the problem wholeheartedly, by the way...Ferrari announced their next latest flagship Sports cars, can I buy two?"
　　 Yang Xiaoman frowned. In fact, she was not heartbroken by money, but she felt a little uncomfortable with Xu Mang's lavish money. He was undoubtedly giving the child a bad impression, thinking that the family was particularly rich.
　　 though...
　　 is really rich, but the child has to instill the concept of being poor at home from a young age, so that he has a spirit of continuous hard work, otherwise he will learn from his father... you need a sports car when you open your mouth, and an airplane when you open your hands.
　　 "No way!"
"You can only buy one!" Yang Xiaoman resolutely rejected Xu Mang's request, and said seriously: "You have to change your bad habits... and let your children see that your father is like this in the future. It will be sad, why is such an excellent mother married to a trash dad."
　　 Xu Mang:? ? ?
　　...
At night,
Xu Mang sat alone in the room and started working. Now he has solved the problem of covering any convex body with long strips. That is to say, Xu Mang 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 the convex body.
However, we still need to think from another angle. Cover a unit sphere with a certain type of ball belt... Specifically, each ball belt is the intersection of the sphere and a specific three-dimensional slat, where the slat is about the ball. A space region sandwiched between two parallel planes symmetrically.
　　 without slats,
　　 The spherical belt is defined in the metric space of the spherical geodesic.
After researching for half an hour, Xu Mang knew that if it is resolved, it must find the smallest sum of width on the ball belt that can cover the unit sphere. Therefore, the width measurement method is different from before. It is defined as the length of an arc instead of a parallel line. Or the Euclidean distance between faces.
"So..." Xu Mang let out a long sigh, and the stone on his heart fell. He hurriedly searched for information with his mobile phone. In a certain paper, he proved a very useful point, and Xu Mang passed By contradiction, try to find contradictions.
　　 is to find a point located on the sphere, but not in any of these ball belts.
"Is that right?"
　　 "It looks like this!" Xu Mang looked at what he wrote, and it seemed that Zone conjecture was not that difficult, but the argument was very complicated, and it took ten years...to solve this problem, and it was natural.
　　 But,
　　 Xu Mang showed a slight smile. He felt that the other party was so arrogant that he was so embarrassed that he would dare to jump out at such a speed? I really don't know how high the sky is.
But there is one sentence. 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. It is conceivable how important it is to reality. In addition to discrete geometry, in high-dimensional It can also be promoted in the space.
　　Even in physics and cosmology, there will be unspeakable promotion.
at the same time,
　　 Yang Xiaoman pouted his mouth and hugged a pillow... his eyes were staring at the silent TV set blankly, his brain full of images of beating Xu Mang, and he took a peek at Xu Mang who was working.
"Humph!"
　　 "I'm angry!" Yang Xiaoman suddenly shouted.
　　 Xu Mang almost didn't get scared to death. He looked at her with a bewildered look, and said helplessly: "I almost didn't get scared into a cardiac arrest by you."
"idiot!"
　　 "Do you know that I am...boring now?" Yang Xiaoman gave a white glance and said seriously: "Talk to me!"
　　"..."
　　 "No time!" Xu Mang frowned and said, "Wait for another hour and remember not to make trouble!"
after that,
　　 Xiaoman looked at her husband and turned his head again, working alone quietly. Perhaps Xu Mang’s words were a bit heavy just now, making this angry little woman realize that she was wrong, but even if she was wrong, she couldn’t admit her mistake.
"I'm angry...I don't love you anymore." Yang Xiaoman got up and sat on the head of the bed, turning her back to Xu Mang and muttering to herself, except that her voice was a bit loud: "Speak well, coax I'll get my heart soon!"
　　(_) Secretly glanced...
　　Result,
　　 Xu Mang did not respond.
"Ugh..."
"I can only run away from home!" Suddenly Yang Xiaoman stood up angrily, took a piece of clothing and put it on his body, but said in his mouth: "It's so cold outside... You must put on clothes, or you will freeze to death."
　　The words fall,
　　(_) Secretly glanced again...
　　 There is still no response.
what's the situation?
　　 Why doesn't this big pig's hoof respond?
　　 Yang Xiaoman: (#￣～￣#)
　　 scum man!
　　 Big Scum!
"Then I'll take another bowl... take the bowl and beg for food." Yang Xiaoman was looking for the bowl in the room with a full face, not knowing how she found it, and found a broken bowl. ...Xiaoman with the bowl in his hand is a little at a loss.
　　 "I'm going to beg for dinner!"
　　 "I'm really going to beg for dinner!" Yang Xiaoman shouted.
In the face of Xiaoman’s drama performance, Xu Mang’s heart collapsed, but it was more of a love. He didn’t expect his wife to be very talented in acting. It was obviously his fault, but he tried to push the problem to others. .
　　 is so cute!
　　 "How about..."
　　 "You take two bowls?" Xu Mang said with a smile.
　　 Seeing Xu Mang finally took care of himself, Xiaoman hurriedly leaned to his side and said with a smile, "Are you going to beg with me?"
"Do not!"
　　 "Sponsor you to open a branch." Xu Mang smiled.
　　 Next second,
　　 Yang Xiaoman was so angry that he threw the stainless steel bowl on the ground, grabbed Xu Mang’s ear, and said angrily: "My old lady is not alive...you must be killed!"
　　 "Ohhhhhh..."
　　 Xu Mang grabbed Xiaoman's hand and hurriedly begged for mercy: "Don't go, can you stay? I beg you."
　　 Yang Xiaoman released his hand and said with a grieved expression: "Then I will reluctantly promise you..."
　　 Xu Mang: (°°〃)
　　 My god!
　　 After being pregnant, I feel that Xiaoman's IQ is less than 30.
after that,
Xiaoman clings to Xu Mang's arms, while feeling the warmth from his man, watching him solve one problem after another, the arrogance in his heart...Although this big idiot is worthless under the mountain, just love himself is enough Up.
　　 "What does this mean?" Yang Xiaoman asked.
"I constructed a special set of points in the three-dimensional space, so that at least one point is not in the area covered by the plank." Xu Mang said casually: "If the whole set of points is inside the ball, then find another point on the sphere. A point that is not covered by the plank, that is, not covered by the ball belt, is relatively easy."
"If any point in the set happens to be outside the sphere, you can use a larger ball belt instead of several smaller ball belts, the width of which is equal to the width of the larger ball belt." Xu Mang said: "This way It is possible to reduce the number of ball belts in the initial problem without affecting the width and sum."
　　 The corners of Xiaoman's eyebrows were slightly raised, and he said seriously: "Does it mean that a certain point on the sphere will be determined to be outside of these balls?"
　　 "Oh!"
Xu Mang looked surprised, looked at Xiaoman's profile ~EbookFREE.me~ and said: "My beautiful girl is...so smart? So beautiful and smart, Xiaoman...can you give me something? Leave some living space for others?"
　　 "hate"
　　 "You idiot!" Yang Xiaoman quietly twisted Xu Mang's thigh: "When will it end?"
"Soon..."
"It's not a big problem either." Xu Mang smiled and said calmly: "It has been solved now... but I want to shorten the process a bit. The answer given to the whole world by that Dika genius is too long, I think It can be shortened a bit."
　　 "Also...it seems to extend another conjecture..." Xu Mang continued: "Another more basic conjecture about spherical coverage..."
　　 Yang Xiaoman said angrily: "Hello? Are you going to end it? Almost it will do...what extends another conjecture, the old lady forbids you to extend it!"
　　 "Hey..."
"Actually I already know the answer... In my conjecture, the ball belt covering the sphere does not need to be centrally symmetrical." Xu Mang smiled: "But the paper is not enough, I don't bother to write... Think about it."
　　 a moment,
　　 Xu Mang put down the pen silently.
"solved?"
"solved!"
　　 "What... is this a conjecture known as French mathematics genius, it took ten years to solve?" Yang Xiaoman said with disappointment: "So the gap between you is so big?"
　　 One took ten years, the other took several hours...
　　 My god!
　　 It turns out that the well-known big V is boasting such a person?
　　......
