After dinner,

Xu Mang returned to his usual state, the state where he was just waiting to die. How to capture Zhuang Qingyun was no longer a problem. As long as his wife stood by his side, even the emperor and his employer were not afraid.

at this time,

Yang Xiaoman is cleaning the house. Originally, this was not her business, but Xu Mang will be under pressure in the near future, so she has taken over the work at home. She has no choice... She is so gentle and virtuous, but it is a pity.

.. After being Xianhui for less than five minutes, when I saw Xu Da Zhu’s trotters paralyzed on the sofa, I felt a sense of imbalance in my heart.

Why?

Why is my mother doing housework?

Is there any little fairy in this world who does housework anymore?

"Hello!"

"You idiot!" Yang Xiaoman said angrily: "You saw me mopping the floor, why did you have the nerve to continue lying down? You shouldn't have snatched my mop at this time, and then asked me with concern if I was tired.

Bad? Rather than pretending not to see it.”

"..."

"Honey... let's buy a sweeping robot." Xu Mang said seriously: "How about... buy a villa, change all the furniture to smart, connect to the wifi at home, and then operate it with your mobile phone

, For example, in winter, turn on the central air conditioner half an hour in advance, or the sweeping robot automatically starts working."

Hearing Xu Mang's words, Yang Xiaoman fell into deep thought. Although this villa is worth more than 200 million, the area is not very large and the decoration is not very luxurious. It is expensive because of the location. It is in the core of the Magic City.

, and then he was promoted to the sky by real estate speculators, but that was actually it.

"It's time to change houses..." Yang Xiaoman frowned and said seriously: "We will get married next year, and we will have children the year after that. We should plan in advance for the future of our children. I will go find out tomorrow.

Wherever the best school district in Shanghai is, we will buy there!"

"A room in a school district?"

"No need...it's the same wherever you study." Xu Mang said calmly: "You have a PhD in economics and own several high-tech materials companies, and I am a professor of physics and have won the Nobel Prize in Physics.

This kind of gene... you don’t need to go to school at all, you are already invincible from birth.”

"fart!"

"Although our children are born with excellent conditions, the acquired environment may affect their future development. You don't know anything..." Yang Xiaoman rolled his eyes and said angrily: "No matter how smart a person is, if he is surrounded by

If the environment is not good, you will go astray, just like you."

The words fell,

Yang Xiaoman rolled his eyes and said seriously: "If it weren't for me, you would have...picked up garbage a long time ago. So acquired factors determine the future, while innate factors only determine height. You must buy the best in the entire Magic City.

It’s in a good school district. Anyway, I have a lot of money. Even if I don’t have any money, my grandpa has a lot of money!”

Xu Mang: Embarrassed

I almost forgot...I also have my father-in-law.

"oh!"

Xu Mang continued to slump on the sofa, watching the American TV series "The Big Bang Theory" and crossing his legs. However, his comfortable life was interrupted the next second. Yang Xiaoman kicked Xu Mang in the butt.

, and then jumped on him.

"Why should you feel comfortable while I clean the house?" Yang Xiaoman said angrily.

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

"What's this?"

Taking the document, Yang Xiaoman read it carefully for a long time before realizing that it was a research report on the universal coverage problem. Then he said with surprise: "Husband? You...you solved the problem so quickly? Oh my god.

...0.84409359 square units, which is less than 0.8441153.”

"Um!"

"This is not a big problem. We rely on computers to perform simulation calculations." Xu Mang said calmly: "If you send this value to the blogger, and then upload my content to arxiv, it will be treated as your publication."

"ah?"

"Well!" Yang Xiaoman showed a smile, kissed Xu Mang's face hard, and said coquettishly: "Husband... you are so kind!"

night,

Yang Xiaoman sat on the computer and uploaded this paper with Xu Mang's guidance. Then he wrote his own answer under the blogger's Weibo, and the words in the message

Full of disdain and contempt for bloggers.

certainly,

None of this was Xiaoman's original intention, but she didn't care. However, it was because of these messages that she caused a lot of trouble in the future.

...

a certain community,

Chen Li is a Ph.D. in mathematics from Fuzhou University and is also a leader in related majors. He belongs to the senior level and has high attainments in applied mathematics. Chen Li's strength is algebra. He is engaged in algebra research and has published many articles.

Professional papers.

certainly,

He is only in his early thirties this year. He is relatively young and belongs to the rare category of genius. However, compared with the monster 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 that he can never cross.

At this time, the young doctor was sitting on the bedside holding a tablet computer, chatting with friends online. In fact, in addition to being a doctor, Chen Li is also a great figure on Weibo, and often posts mathematics-related topics.

In terms of content, in today's era, everyone is a master on the Internet, but Chen Li is the real deal.

I am a mathematician (Chen Li): Is anyone there?

Passerby A: Teacher Chen is here?

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

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

Chen Li noticed this friend's message and hurriedly attached his own answer.

I am a mathematician: it can be reduced, but it is too difficult. Currently, 0.8441153 is the limit value. Although in 2005, it was proved that the coverage area of ​​everything cannot be less than 0.832 square units, but no one can do that.

.

I am a mathematician: Don’t think that there is a big gap between 0.8441153 and 0.833. However, this is a result obtained for more than a hundred years. If you want to continue to shrink it, you need to use new mathematical tools.

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

Chen Li closed the chat box and started to browse Weibo. At this time, he had 99 unread messages. The number of unread messages was far less than 99, but he didn't take it to heart at all. Basically, they were just a few

Messages from netizens.

after,

I wrote an article of more than a thousand words, briefly describing the history of the universal coverage problem, from the birth of the problem to the proposal of Parr's hexagon, and then mathematicians continued to modify the Parr's hexagon, striving to be consistent with the problem.

The most perfect solution.

Almost all of Chen Li's articles are free and do not charge any fees. Although Weibo has launched paid question answering or paid article functions, Chen Li feels that fees should not be charged for disseminating mathematical knowledge, which is not conducive to promoting mathematics to the public.

.

soon,

This article was published and received countless comments. Most of the netizens’ answers made Chen Li laugh out loud. This was not a mockery, but a sigh of appreciation for the netizens’ wit. What was originally a serious question was suddenly mocked by the netizens.

Turned into a comedy.

for example,

One netizen vividly described how to plug the hole in his pants:

'Mom, my pants have a lot of holes in them and they have weird shapes!'

Mom blocked my mouth with a wad of colorful banknotes and told me...if I block your hole, I will block all the holes.

Some netizens were even more naughty and asked to change into a pair of pants.

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

certainly,

There are also many arrogant people who bluntly say that the problem of universal coverage is very stupid in itself, because the ultimate ideal of mathematics lies only in theology, and theology cannot be calculated.

Chen Li then selected a few lucky netizens and responded to their messages, mostly explaining the meaning of this question. Many questions seemed stupid, but in fact they required a lot of theory behind them, and some reasons required

be overturned, or re-create a theory.

And this is the meaning of existence, which unintentionally promotes the development of mathematics. In fact, the answer to the question is not important, what is important is the method to solve the problem.

Just when Cheng Cheng was about to turn off the tablet, he accidentally saw the ninety-nine unread messages again. Finally, Chen Li accidentally clicked on it. In fact, he just didn't want to see this number, that's all, and had no other ideas.

but,

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