early morning,

Xu Mang got up early as usual. In fact, he didn't study for too long last night. All this was due to that stupid pregnant woman. I don't know why suddenly... he went crazy and wanted to coax her by himself. Maybe it was because of watching

Douyin’s emotional story.

Glancing at Xiao Man lying next to him, Xu Mang just looked at her quietly. He said that it seemed that he hadn't seen Xiao Man up close for a long time. When he was in high school... he could often see her face to face at close range, and then he

Opportunities like this rarely come around.

Not to mention...

Xiaoman is indeed beautiful, but even if she is as beautiful as a fairy in the sky, no... she is pregnant and has become an expectant mother, and fairies will still win hearts.

At this time,

Xiaoman woke up suddenly, stretched out lazily, and saw Xu Mang looking at her intently, her pretty face blushed slightly, and she said shyly: "What's wrong... with such a look?"

Look at me, we have been together for so long, is this necessary?"

"Well?"

"It's just that I haven't looked at you like this for a long time." Even the unruly Xu Mang became tender at this moment. He stretched out his hand and pinched the little goblin's face and said: "Before... I never thought that I would be like this.

Get married early and become a father so early."

"Um!"

Yang Xiaoman took advantage of the situation and moved closer, then leaned her whole body in Xu Mang's arms, and said softly: "Me too... My mother used to tell me that I wanted to be a nun in the future, but... the world is impermanent.

I actually got married before others and even got pregnant."

"Since I brought you home to meet your parents, my parents have smiled a lot more than before. Now that I'm pregnant again... they are even happier." Yang Xiaoman continued: "Idiot... you said

Is this all fate?"

"Maybe..."

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

"Well?"

"But I read in a magazine that statistically...even if people born at the bottom of society become adults, their unhappy experiences as children will cause them to have very big cognitive defects.

Taste and moral standards will be incompatible with upper class society." Yang Xiaoman said.

"Um!"

"This is just a phenomenon abroad, but it cannot be verified in our country." Xu Mang quietly put his hand into the quilt, touched Xiaoman's belly... Feeling the feeling of life gestating inside, he said seriously:

"We have fundamental differences in education."

"the difference?"

"What's the difference?" Yang Xiaoman asked: "Elite education? I remember the 'Grey Man Theory' of Oxford University. It seems like this is it?"

Xu Mang nodded and said calmly: "The Gray Man Theory states in detail that if an ordinary person has very average qualifications and works very hard, this kind of person is the most pathetic person in the world, and is called a Gray Man by Oxford.

.”

"right!"

"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 showed a smile: "It is impossible to separate personal ideals and the destiny of the country... 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 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 China have always been interconnected. From a historical perspective... this is a truth. For example, in your family's situation... if you go up three generations, you must have a peasant background, and do you have any

Discover..."

"In China... no matter how rich a person is, if he pretends to be a foreign aristocrat, is very out of touch, and has a strong sense of superiority, he will be scolded to death by us." Xu Mang laughed.

Dao: "Even in mythology...there is a gap between us and foreign countries."

"In foreign myths, there are big floods that punish humans, and humans can only kneel down and beg for forgiveness, but here... it has always been Hou Yi who shot the sun and Jingwei who filled the sea. Since ancient times, we have worshiped Gai Gai.

Warrior of fate." Xu Mang freed up his other hand and pinched Xiaoman's cheek.

"It is no exaggeration to say that most people living on this land have the courage to face fate and never compromise. This is unmatched by any country in the world." Xu Mang said: "So

..."

So far,

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

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

"So the reason why you and I can come together is not the so-called entanglement of fate, but the happiness we strive for." Xu Mang said: "This is what we strive for ourselves, not a gift from God, and we do not need to attribute happiness to fate.

.”

actually,

There is another meaning in Xu Mang's words. He secretly checked Weibo yesterday and found that many people have been led astray by the well-known big Vs. They really believe in their theories and think that China is not good.

Nothing works.

It's interesting when I think about it...

"husband!"

"You're so right!" Yang Xiaoman was so excited that she directly hugged Xu Mang's neck, then moved closer, and kissed Xu Mang fiercely... almost kissing Xu Mang's bald skin.

before,

Xiaoman has always thought that this was fate's arrangement, allowing two people who had nothing to do with each other to end up together. But... now she suddenly felt that this was clearly the happiness she had striven for, so why should she attribute it to fate?

After Ni Ni Wai Wai Wai for an hour, Yang Xiaoman suddenly asked: "When will you go back?"

"Tomorrow afternoon." Xu Mang said, "I'm not in a hurry anyway. Once I solve the zone conjecture, I can solve it tonight."

"ah?"

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

"..."

"It's not because of you!" Xu Mang said angrily: "Apply for three hours tonight... Don't disturb 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 worried about money, but she felt a little unhappy about Xu Mang spending money so lavishly. He was undoubtedly giving a bad impression to the children, thinking that the family was very, very rich.

Although...

He is really rich, but the concept of poverty in the family must be instilled in the child from an early age, so that he has a spirit of continuous striving for excellence, otherwise he will learn from his father... He wants a sports car when he opens his mouth, and wants an airplane when he opens his hands. Is this okay?

"no!"

"You 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, if your children see their dad like this, they will definitely

I will be sad, why such a wonderful 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. In other words, 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 the convex body.

But we still need to think about it from another angle, using a certain type of ball tape to cover a unit sphere... Specifically, each ball tape is the intersection of the sphere and a specific three-dimensional batten, where the batten is about the ball.

A region of space centered symmetrically between two parallel planes.

No need for slats,

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

After studying for half an hour, Xu Mang knew that if he could solve the problem, he must find the minimum width sum on the spherical belt that can cover the unit sphere. Therefore, the width measurement method is different from before. It is defined as the length of the arc rather than the parallel line.

or the Euclidean distance between faces.

"That's it..." Xu Mang took a long breath, and the stone that was weighing on his heart fell. He hurriedly searched for information on his mobile phone. In a certain paper, a very useful point was proved, and Xu Mang passed

Proof by contradiction, trying to find the point of contradiction.

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

"is that so?"

"It seems like this!" Xu Mang looked at what he had written. It seemed that the zone conjecture was not that difficult, but the argument was very complicated. It was only natural that it would take ten years... to solve this problem.

but,

Xu Mang showed a smile. He felt that the other party was so arrogant that he dared to jump out at such a speed? He really didn't know how high the sky was and how high he was.
