I really don't want to lie down and win

early morning,

Xu Mang got up early as usual. He didn't study for too long last night. All of this was due to that stupid pregnant woman. I don't know why... he went crazy and wanted to coax her by himself. Douyin's emotional story.

Glancing at the woman lying beside him, Xu Mang just looked at her quietly, saying that he hadn't seen Xiaoman up close for a long time. In high school...but he could often see Xiaoman face to face at close range, and then it was very Such opportunities are rare.

let alone...

Xiaoman is indeed beautiful, but even if she is as beautiful as a fairy in the sky, she is still pregnant and becomes a mother-to-be, and the fairy will still move everyone's heart.

At this time,

Xiaoman woke up suddenly, stretched her waist lazily, and saw Xu Mang staring at her intently, with a slight blush on her pretty face, and said shyly, "What's the matter...with this kind of look... Look at me, we've been together for so long, is it necessary?"

"Uh?"

"It's just that I haven't looked at you like this for a long time." Even Xu Mang, who is as arrogant as Xu Mang, will become tender at this moment, stretched out his hand to pinch the little goblin's face, and said, "I... never thought that I would be like this before." Get married early and become a father so early."

"Ok!"

Yang Xiaoman took advantage of the situation and moved a little closer, then clinging to Xu Mang's arms, he said softly, "Me too...my mother used to say that I was going to be a nun in the future, but...the world is impermanent, I actually got married before anyone else, and even got pregnant with a child."

"Since I brought you home to meet my parents, my parents smile a lot more than before, and now I'm pregnant again...the two are happier." Yang Xiaoman continued: "Stupid... you said Is this all fate?"

"maybe..."

"But we Hua people don't believe in fate." Xu Mang said with a smile: "The vast majority of people are fighting against fate."

"Uh?"

"However, I read from a magazine that statistically speaking... people who were born at the bottom of society will have a very big cognitive defect even after they grow up. Taste and moral standards will be out of place in high society," Yang Xiaoman said.

"Ok!"

"This is just a foreign phenomenon, but it cannot be verified in our country." Xu Mang quietly put his hand under the quilt, touched Xiaoman's belly... feeling the feeling of life being born inside, and said seriously: "We have fundamental differences in education."

"the difference?"

"What's the difference?" Yang Xiaoman asked, "Elite education? I remember the Gray Man Theory from Oxford University, so it seems like that?"

Xu Mang nodded, and said calmly: "The gray man theory shows in detail that if an ordinary person has very ordinary aptitude and works very hard, such a person is the most pathetic person in the world, and is called a gray man by Oxford." .”

"Correct!"

"I've heard of it too." Yang Xiaoman said, "I'm particularly disgusted with the so-called gray man theory."

"so..."

"Our topic has to go back to the previous theory." Xu Mang smiled, "Personal ideals and the destiny of the country cannot be separated... because as long as you are in Huaguo, as long as you are willing to work hard, love learning and dare to work hard , you can go all the way from a backward village to a university like Tsinghua University and Beijing University.”

at this time,

Xu Mang continued: "The classes in Huaguo have always been interconnected. From a historical point of view... this is a truth. For example, in your family's situation... if you look up three generations, you must have a peasant background, and do you have any background?" Discover..."

"In Huaguo... no matter how rich a certain person is, if he pretends to be a certain foreign aristocrat, he is very ungrounded and has a strong sense of superiority, and he will be scolded to death by us." Xu Mang laughed Dao: "Even in the myth... there is a gap between us and foreign countries."

"In foreign mythology, it is the great flood that punishes human beings, and human beings can only kneel down and beg for forgiveness, but here... Houyi has always shot the sun and Jingwei filled the sea. We have worshiped the change against the sky since ancient times. A brave warrior." Xu Mang freed up his other hand and squeezed Xiaoman's cheek.

"It's no exaggeration to say... most of the people living in this land have the courage to face fate without compromise, which is unmatched by any country in the world." Xu Mang said: "So ..."

Speaking of here,

Xu Mang stopped suddenly, and looked at the annoying little fairy with a smile.

"So what?" Yang Xiaoman pouted, and said angrily, "Don't be tricky, tell me quickly!"

"So it's not the so-called entanglement of fate that you and I can get together, but the happiness we fought for." Xu Mang said, "This is what we fought for, it's not a gift from heaven, and we don't need to attribute happiness to fate." .”

in fact,

There is another meaning in Xu Mang's words. He quietly checked Weibo yesterday and found that many people were led astray by well-known big Vs. They really believed their theory, thinking that Huaguo just couldn't do it. Can't do anything.

Interesting to think about...

"husband!"

"You're so right!" Yang Xiaoman was so excited that he put his arms around Xu Mang's neck, and leaned forward, kissing Xu Mang hard... almost kissed Xu Mang's bald skin.

before,

Xiaoman always felt that it was an arrangement of fate that made the two people who had nothing to do with each other finally get together, but...now she suddenly felt that this was clearly the happiness she had won, so why should she attribute it to fate?

Tired and crooked for an hour, Yang Xiaoman suddenly asked: "When are you going back?"

"Tomorrow afternoon." Xu Mang said, "Anyway, I'm not in a hurry. After I solve the Zone conjecture, I can solve it tonight."

"what?"

"So fast?" Yang Xiaoman was stunned for a moment, then said in surprise: "Last night...you didn't do anything to solve the problem at all."

"..."

"It's not because of you!" Xu Mang said angrily, "Application for three hours tonight...don't disturb me, let me solve the problem wholeheartedly, by the way...Ferrari announced their next latest flagship Sports car, can I buy two?"

Yang Xiaoman frowned. In fact, she didn't feel sorry for money, but just felt a little bit uncomfortable with Xu Mang's extravagant spending. He was undoubtedly giving the child a bad impression, thinking that the family was very, very rich.

Although..

He is really rich, but the child has to inculcate the concept of being poor at home, so that he has a spirit of continuous improvement, otherwise he will learn from his father... if you open your mouth, you need a sports car, and if you open your hands, you need an airplane.

"no!"

"I can only buy one!" Yang Xiaoman resolutely rejected Xu Mang's request, and said seriously: "You have to change your bad habits... In the future, let the children see that their father is like this. It will be sad, why such an excellent mother married a useless father."

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 strips 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.

But it takes another way to think about it, to cover a unit sphere with some sort of band... specifically, each band is the intersection of the sphere with a specific three-dimensional slat, where the slat is about the sphere The centrosymmetric region of space sandwiched between two parallel planes.

without slats,

And the spherical zone is defined in the metric space of the spherical geodesic.

After researching for half an hour, Xu Mang knew that if he could solve it, he had to find the minimum sum of the widths of the balls that could cover the unit sphere, so the width measurement method was different from before, it was defined as the length of an arc, not a parallel line or the Euclidean distance between faces.
