Chapter 825

After dinner,

after dinner, Xu mang returned to his usual state. In his former state of muddling and waiting to die, it was no longer a problem for him to win over Zhuang Qingyun. As long as his wife stood beside him, even the emperor's labor and capital were not afraid.

At this time,

Yang Xiaoman is cleaning the house. Originally, this is not her business, but in the near future, Xu mang will be under pressure, so she has to pack the work of the family. She can't help but be so gentle and virtuous. Unfortunately, after less than five minutes of virtuous, she sees Xu Da pig's hooves lying on the sofa, and the sense of imbalance in her heart surges up.

Why?

Why is my mother doing housework?

Which fairy in the world does housework again?

"Hello

"Big fool!" Yang Xiaoman said angrily: "you see me mopping the floor, do you want to continue lying? I shouldn't have robbed my mop at this time and asked me with concern whether I was tired or not? Not as if you didn't see it. "

"..."

"wife... Let's buy a sweeping robot." Xu said seriously: "or... Buy another villa, all the furniture will be changed into intelligent, connected to the WiFi at home, and then you can operate with your mobile phone. For example, in winter, you can turn on the central air conditioner half an hour in advance, or the sweeping robot will start working automatically."

Hearing Xu Mang's words, Yang Xiaoman fell into a deep thought. Although the villa is worth more than 200 million yuan, the area is not very large, and the decoration is not very luxurious. The most important thing is that the location is OK, which is in the core of the magic capital, and then it was fired by the real estate speculators. In fact, that's it.

"It's time to change the house..." Yang Xiaoman frowned and said seriously: "next year we'll get married, and the next year we'll have children. We should plan ahead for the future of our children. Tomorrow I'll ask where the best school district of Mordor is, and we'll buy there!"

"School district room?"

"No need... It's the same everywhere you read it." "You are a doctor of economics and have several high-tech material companies. I am a professor of physics. I have won the Nobel Prize in physics. I don't need to go to school. I'm invincible when I was born."

"Fart!"

"Although our children's congenital conditions are excellent, the environment after tomorrow may affect the future development, you don't know anything..." Yang Xiaoman said angrily with a white eye: "even if the smart people, if the surrounding environment is not good, they will go astray, just like you."

As a result, Yang Xiaoman gave a blank look and said seriously: "if there was no old mother, you would have picked up the garbage for a long time. So the postnatal factors determine the future, while the congenital factors only determine the height. We must buy the best school district location of the whole devil. Anyway, I have money. Even if there is no money, my grandfather has a lot of money!"

Xu Mang: I almost forgot... And my father-in-law.

"Oh

Xu mang continues to collapse on the sofa, watching the American TV series "the big bang of life", and then cocks his legs. However, the next second his comfortable life is interrupted. Yang Xiaoman gives a foot to Xu Mang's butt, and then he pours on him.

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

"Comfortable together, comfortable together." Xu mang holds Xiaoman helplessly, tilts his head and continues to watch American TV series. In this way, they boil for an hour until Xiaoman sees a document under his handbag.

"What is this?"

After taking this document, Yang Xiaoman read it carefully for a long time before he knew that it was a research report on universal coverage, and then he said with surprise: "husband? You... You solved the problem so quickly? My God... 0.84409359 square units, which is less than 0.8441153. "

"Well!"

"It's not a big problem. It's a computer simulation." Xu said calmly: "you send this value to that blogger, and then upload my content to arXiv, as you publish it."

"Ah?"

"Well!" Yang Xiaoman showed a smile, mercilessly kiss Xu Mang's face, coquettish way: "husband... You are so good!"

At night,

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

Of course,

all this is not Xiaoman's original intention, but she doesn't care. However, it is these messages that cause a lot of trouble in the future.

...

in a community,

Chen Li is a Ph.D. in mathematics of Fuda University, and also a leader of related majors. He belongs to a positive high level and has high attainments in Applied Mathematics. Chen Li's strong point is algebra. He is engaged in algebra research and has published many professional essays.Of course,

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

At this time, the young doctor was sitting at the head of his bed, holding a tablet computer and chatting with his friends on the Internet. In fact, apart from being a doctor, Chen Li is also a God on microblog. He often sends some content about mathematics. In this era, everyone is a God on the Internet, but Chen Li is the real one.

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

Passerby A: is Mr. Chen here?

Passerby B: why didn't Mr. Chen tweet today?

Passerby C: is there really no lower value than 0.8441153 about universal coverage?

Chen Li noticed this friend's news and quickly attached his reply.

I am a mathematician: it can be reduced, but it is too difficult. At present, 0.8441153 is already the limit value. Although in 2005, it was proved that the universal coverage area could not be less than 0.832 square units, no one could do that.

I'm a mathematician: you don't think that there is a big gap between 0.8441153 and 0.833. However, this is the result of more than 100 years. If we want to continue to narrow down, we need to use new mathematical tools.

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

Chen Li turned off the chat box and began to visit Weibo. At this time, he had 99 unread messages. The number of messages that did not expire was far from known. However, he did not pay attention to it. Basically, they were messages from some netizens.

After that,

wrote an article of more than 1000 words, which briefly described the history of the universal covering problem, from the birth of the problem to the proposition of the PAL hexagon, and then mathematicians constantly revised the parr hexagon to strive for the most perfect solution.

Almost all of Chen Li's articles are free of charge, and no fees are collected. Although the micro blog has launched a charging answer or a paid article function, Chen Li thinks that the dissemination of mathematical knowledge should not be charged, which is not conducive to the promotion of mathematics to the public.

Soon,

this article was published, and numerous people's messages were welcomed. Most of the netizens' answers made Chen Li laugh. This is not a mockery, but a feeling of netizens' tact. Originally, a serious question, they were made into a comedy by sand sculpture netizens.

For example,

a netizen vividly described how to block the hole in the pants:

"Mom, my pants have several holes, which are strange shapes!"

Mom stopped my mouth with a bunch of colorful bills, and told me... Stop your hole, you'll block all the holes.

Some netizens are more naughty and ask for a pair of trousers.

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

Of course,

there are also quite a lot of elites. These people are very stupid when they talk about the problem of universal coverage, because the ultimate ideal of mathematics is only in theology, and theology can't calculate it.

Chen Li immediately selected a few lucky netizens to reply to the messages of others, more to explain the significance of the existence of this problem, many questions seem stupid, in fact, need to use a lot of theories behind, and some reasons need to be overturned, or recreate a theory.

This is the meaning of existence, which has promoted the development of mathematics unconsciously. In fact, the answer to the problem is not important, but the solution to the problem.

Just when he was about to turn off the tablet computer, he inadvertently saw the 99 unread messages. Finally, Chen Li made a fuss. In fact, he just didn't want to see the number. That's all. There was no other idea.

However,

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

Originally thought it was a journey of laughter, but a few minutes later, Chen Li saw a message from a netizen, on which were some sermons. He warned himself not to bring the wrong remarks into the public view, so as not to cause bad influence. A set of numbers and a connection are behind.

Eh?

0.84409359？

What does that mean?

Chen Li feels a bit bad. Is this group of mysterious figures the latest universal coverage area? It's very possible... But the problem comes again. Will you believe a group of numbers written by netizens at will?

As a Ph.D. in Mathematics Department of Fuda University, Chen Li still has a trace of pride. He did not drop this group of mysterious numbers on the spot. However, the following connection attracted his attention. This... Seems to be the paper connection of arXiv!

"This..."

"have you met a cruel man?" Chen Li frowned and said to himself in disbelief: "did you even publish a paper on arXiv? It's not... Maybe it's someone else's, he just reprints it, arXiv... This kind of document pre included website, there are not many high-quality papers. "With a strong curiosity,

Chen Li went in. Originally, he did not have much expectation and could see the birth of a miracle. However, after only one minute, his expression became extremely exaggerated and almost distorted. The above content has subverted his concept of universal coverage.

Atomic scissors?

New computer mathematical image tools?

I haven't heard of it before!

Chen Li quickly downloaded this paper, although he has not read it carefully, but through the front part, you can know that this paper is not simple. After he checked the account information of the message, he found many secrets.

"Mordor?"

"Or a woman?"
