After dinner,

Xu Mang returned to his usual state, the former state of eating and waiting for death, it is no longer a problem for how to win Zhuang Qingyun, as long as his wife is standing by his side, even the emperor is not afraid of labor.

At this point,

Yang Xiaoman is cleaning the house, originally this is not her business, but Xu Mang will be under pressure in the near future, so she has taken care of the work at home, there is no way... It's so gentle and virtuous, but it's a pity... It's just that after less than five minutes of virtuousness, after seeing Xu Da pig's trotters paralyzed on the sofa, the sense of imbalance in his heart came up.

Why?

Why is the old lady doing housework?

What little fairy in this world does housework again?

"Hey!"

"Big stupid!" Yang Xiaoman said angrily: "You see my mother mopping the floor, and you are embarrassed to continue lying down? ”

“...”

"Wife... Let's buy a robot vacuum. Xu Mang said seriously: "Or... Buy another villa, all the furniture is changed to smart, connect to the Wifi at home, and then you can use your mobile phone to operate, such as in winter, half an hour in advance, turn on the central air conditioner, or the sweeping robot will automatically start working. ”

Hearing Xu Mang's words, Yang Xiaoman fell into deep thought, although this villa is worth more than 200 million, in fact, the area is not very large, and the decoration is not very luxurious.

"It's time to change the house..."Yang Xiaoman frowned and said seriously: "We will get married next year, and we should have children the year after tomorrow, we should plan in advance for the future of our children, tomorrow I will inquire where the best school district in the magic capital is, and we will buy there!"

"School district room?"

"No, no... It's the same everywhere you read. Xu Mang said indifferently: "You are a doctor of economics, you own several high-tech materials companies, and I am a professor of physics and have won the Nobel Prize in Physics. You don't need to go to school at all, you're already invincible when you're born. ”

"Fart!"

"Although our children are very good in congenital conditions, the acquired environment may affect their future development, and you don't understand anything..."Yang Xiaoman glanced at him and said angrily: "Even if you are smart, if the surrounding environment is not good, you will go astray, just like you." ”

Words fall,

Yang Xiaoman glanced at him and said seriously: "If it weren't for my wife, you would have been... I have already picked up garbage, so the acquired factor determines the future, and the innate factor only determines the height, and I must buy the best school district location in the whole magic capital, anyway, my wife I have money, even if the money is gone, my grandfather has a lot of money!"

Xu Mang: Embarrassed

I almost forgot... and his own father-in-law.

"Oh!"

Xu Mang continued to paralyze on the sofa, watching the American drama "The Big Bang Theory", and then crossed Erlang's legs, but his comfortable life was interrupted in the next second, Yang Xiaoman kicked Xu Mang's ass, and then pounced on him.

"Why are you comfortable, I have to clean?" Yang Xiaoman said angrily.

"Comfortable together, comfortable together. Xu Mang helplessly hugged Xiao Man, tilted his head and continued to watch American dramas, just like that... The two stayed up for an hour until Xiao Man saw a document pressed under his handbag.

"What is this?"

After taking this document, Yang Xiaoman looked at it carefully for a long time, only to know that this was a research report on the problem of universal coverage, and then said with a surprised face: "Husband? You've solved the problem so quickly? Oh my God... 0.84409359 square units, which is less than 0.8441153. ”

"Hmm!"

"It's not a big deal, it's a computer. Xu Mang said indifferently: "Anyway, you send this value to the blogger, and then upload my content to arXiv, just as you publish." ”

"Huh?"

"Hmm!" Yang Xiaoman showed a smile, kissed Xu Mang's face fiercely, and said coquettishly: "Husband... You're so nice!"

night

Yang Xiaoman sat on the computer, and under Xu Mang's guidance, uploaded this paper, and then wrote his answer under the blogger's Weibo, and the words of the message were full of disdain and contempt for the blogger.

Of course

All this was not Xiao Man's intention, but she didn't care, but it was because of these messages that it caused a lot of trouble in the future.

...

A community,

Chen Li is a Ph.D. in mathematics at Fudan University, and is also a leader in related majors, belonging to the senior level, with high attainments in applied mathematics, while Chen Li's strength is algebra, engaged in algebra research, and has published a number of professional papers.

Of course

He is only in his early thirties this year, relatively very young, and belongs to a rare genius category, but compared with the demon Xu Mang, it is more than one level lower, Chen Li has never thought of surpassing Xu Mang, in his eyes, Xu Mang is a mountain that he can never cross.

At this time, this young doctor is sitting at the head of the bed with a tablet, chatting with friends on the Internet, in fact, Chen Li is not only a doctor, he is also a god on Weibo, often posting some content related to mathematics, in this era, everyone is a god on the Internet, but Chen Li is the real one.

I'm a mathematician (Chen Li): Anyone?

Passerby A: Teacher Chen is here?

Passerby B: Why didn't Mr. Chen post on Weibo today?

Passerby C: Speaking of Mr. Chen's question about universal coverage, is there really no lower value than 0.8441153?

Chen Li noticed the friend's news and hurriedly attached his answer.

I'm a mathematician: it can be scaled down, but it's too difficult, and at the moment this 0.8441153 is already the limit value, although in the year 05, it was proved that the universal coverage area could not be less than 0.832 square units, but no one could do that.

I'm a mathematician: don't think that 0.8441153 is a big gap from 0.833, but this is the result of more than 100 years, and if you want to continue to shrink, you need to use new mathematical tools.

Passerby C: Oh... Forget it, I wanted to pick it up, but it seems impossible.

Chen Li closed the chat box and began to visit Weibo, at this time he had ninety-nine unread messages, but the number of expired was far from knowing ninety-nine, but he didn't pay attention to it at all, basically some netizens' messages.

afterwards

Wrote an article of more than 1,000 words, briefly describing the history of the universal coverage problem, from the birth of the problem to the proposal of the Parr hexagon, and then the mathematicians continued to revise the Parr hexagon to strive for the most perfect solution.

Almost all of Chen Li's articles are free and do not take any fees, although Weibo has launched a paid answer question, or a paid article function, Chen Li feels that there should be no fee for disseminating mathematical knowledge, which is not conducive to promoting mathematics to the public.

soon

This article was published, and countless messages were ushered in, and most of the netizens' answers made Chen Li laugh, which was not a mockery, but a sigh of wit from netizens.

Like what

A netizen vividly described how to plug the hole in the top of the pants:

'Mom, my pants are torn with several holes, weird shapes!'

Mom gagged me with a stack of colorful bills and told me... Plug this hole of yours, and you plug all the holes.

Some netizens were even more naughty and asked for a change of pants.

There are also some boring netizens who discuss what kind of family this is.

Of course

There are also quite a few people who speak out about the problem of universal coverage, which is very stupid in itself, because the ultimate ideal of mathematics is only in theology, and theology is incalculable.

Chen Li immediately selected a few lucky netizens and replied to their messages, more to explain the meaning of the existence of this problem, many questions seem stupid, but in fact there are many theories behind them, and some reasons need to be overturned, or a new theory is created.

And this is the meaning of existence, which inadvertently promotes the development of mathematics, in fact, the answer to the problem is not important, what matters is the solution to the problem.

Just when he was about to turn off the tablet, he inadvertently saw the ninety-nine unread messages again, and finally Chen Ligui nodded his head to the gods, in fact, he just didn't want to see this number, that's all, there was no other idea.

But

Chen Li was still attracted by the interesting messages of netizens, and read them one by one.

originally thought it was a laughing trip, but a few minutes later, Chen Li saw a message from a netizen, on which were some preachy words to himself, warning himself not to bring wrong remarks into the public eye, so as not to cause a bad impact, followed by a set of numbers and a connection.

Belch?

0.84409359？

What does that mean?

Chen Li felt a little wrong, could this mysterious set of numbers be the latest universal coverage area? But the question arises again, will I believe a set of numbers written by netizens at random?

As a doctor of the Department of Mathematics of Fudan University, Chen Li still had a hint of arrogance, and rejected this group of mysterious numbers on the spot, but a connection behind it caught his attention, which... This seems to be arXiv's thesis connection!

"This..."

"Ran into a ruthless person?" Chen Li frowned, and said to himself in disbelief: "You actually posted a paper on arXiv? Maybe someone else sent it, he just reprinted it, arXiv... This kind of document pre-inclusion website, there are not many high-quality papers. ”

With a strong sense of curiosity,

Chen Li clicked in, he didn't have much expectation to see the birth of a miracle, but after only a minute, his expression became extremely exaggerated, almost distorted together, and the content on it had subverted his concept of the problem of universal coverage.

Atomic scissors?

A new computer math graphics tool?

I've never heard of it before!

Chen Li hurriedly downloaded this paper, although it has not yet = read carefully, but through the previous part, you can know that this paper is not simple, and then he checked the account information of the message, and found a lot of secrets.

"Demon Capital?"

"Still a woman?"

......
