I really don't want to lie down and win

Yang Xiaoman rolled her eyes, and said seriously: "If it weren't for me, you would have... picked up trash long ago, so acquired factors determine the future, while innate factors only determine height, you must buy the most Good school district location, anyway, I have plenty of money, even if I have no money, grandpa has a lot of money!"

Xu Mang: 囧

I almost forgot...and my old husband.

"Oh!"

Xu Mang continued to slump to death on the sofa, watching the American drama The Big Bang Theory, and then crossed his legs, but his comfortable life was interrupted in the next second, Yang Xiaoman kicked Xu Mang's ass, tight Then it jumped on him.

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

"Be comfortable together, be comfortable together." Xu Mang hugged Xiaoman helplessly, tilted his head and continued to watch American dramas, and just like that...the two stayed up for an hour, until Xiaoman saw a copy under the handbag.

"what is this?"

After taking this document, Yang Xiaoman looked at it carefully for a long time before realizing that it was a research report on the universal coverage problem, and then said with a face full of surprise: "Husband? You... you solved the problem so quickly? My God ...0.84409359 square units, which is less than 0.8441153."

"Ok!"

"It's not a big problem. Computers are used to perform simulation calculations." Xu Mang said calmly, "Say you send this value to that blogger, and then upload my content to arXiv, it will be treated as your publication."

"what?"

"Yeah!" Yang Xiaoman showed a slight smile, kissed Xu Mang's face fiercely, and said coquettishly, "My husband...you are so kind!"

night,

Sitting on the computer, Yang Xiaoman uploaded this article under Xu Mang's guidance, and then wrote his answer under the blogger's Weibo, and the words in the message Full of disdain and contempt for bloggers.

of course,

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

...

a neighborhood,

Chen Li is a Ph.D. in Mathematics at Fuda University, and is also the leader of 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 papers professional theory.

of course,

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

At this time, the young doctor was sitting on the bedside holding a tablet computer, chatting with friends on the Internet. In fact, besides being a doctor, Chen Li is also a master on Weibo, who often posts some mathematics-related things. Content, in this day and age, everyone is a master on the Internet, but Chen Li is the real one.

I'm mathematician Chen Li: Is there anyone?

Passerby A: Teacher Chen is here?

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

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

Chen Li noticed this friend's news, and hastily attached his own answer.

I am a mathematician: it can be reduced, but it is too difficult. The current value of 0.8441153 is already the limit value. Although in 0.832, it was proved that the universal coverage area cannot be less than [-] square units, but no one can do that. .

I'm a mathematician: Don't think that 0.8441153 is far from 0.833. However, this is the result of more than 100 years. If you want to continue to shrink, you need to use a new mathematical tool.

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

Chen Li turned off the chat box and started browsing Weibo. At this time, he had 99 unread messages, but the number of expired messages was far from 99, but he didn't take it to heart at all. Most of them were comments from some netizens.

after that,

I wrote a chapter of more than 1000 words, briefly describing the history of the universal covering problem, from the birth of the problem to the proposal of the Pall hexagon, and then mathematicians constantly correct the Pall hexagon, and strive to match the most perfect solution.

Almost all of Chen Li's chapters are free, without any fees. Although Weibo has launched a fee-based answering function, or a fee-based chapter function, Chen Li feels that spreading mathematics knowledge should not charge fees, which is not conducive to promoting mathematics to the public. .

quickly,

This article was published, and there were countless comments from people. The answers from most of the netizens made Chen Li laugh out loud. This was not a mockery, but a sigh of gratitude for the wit of the netizens. It was originally a serious question. became a comedy.

such as,

One netizen vividly described how to plug the hole in the trousers:

Mom, there are several holes in my pants, which are in strange shapes!

Mom gagged me with a wad of brightly colored bills and told... Plug your hole and you plug all the holes.

Some netizens were even more mischievous and asked for a pair of pants.

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

of course,

There are also quite a few scumbags. These people bluntly say that everything covers the problem, which is very stupid in itself, because the ultimate ideal of mathematics is only in theology, and theology cannot be calculated.

Chen Li immediately selected a few lucky netizens and replied to their messages, more to explain the meaning of the existence of this question. Many questions seem to be stupid, but in fact many theories are needed behind them, and some reasons need to be solved. To be overthrown, or to reinvent 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, but the solution to the problem is important.

Just when Cheng Jian was about to turn off the tablet, he accidentally saw the 99 unread messages again. In the end, Chen Li clicked it out of nowhere. In fact, he just didn’t want to see this number, that’s all, he had no other thoughts.

but,

Chen Li was still attracted by the interesting comments 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, which contained some words of preaching to himself, warning himself not to bring wrong remarks into the public eye, so as not to cause unfavorable Good impact, followed by a set of numbers and a connection.

Uh?

0.84409359?

What does it mean?

Chen Li felt something was wrong. Could this group of mysterious numbers be the latest universal coverage area?It's very possible...but here comes the question again, will I believe a set of numbers randomly written by netizens?

As a Ph.D. student in the Department of Mathematics of Fuda, Chen Li still had a hint of arrogance, and rejected this group of mysterious numbers on the spot. However, a link later caught his attention. This seems to be from arXiv On the connection!

"This..."

"Meet a ruthless person?" Chen Li frowned, and said to himself in disbelief: "You actually posted it on arXiv? No... maybe someone else posted it, he just reposted it, arXiv... .There are not many high-quality papers on this kind of pre-recorded websites.”

With strong curiosity,

Chen Li clicked in. Originally, he didn't have much expectation, and he could see the birth of a miracle. However, after only 1 minute, his expression became extremely exaggerated, and almost all of them were distorted. The concept of the universal coverage problem.
