Chapter 809: Math Problems on Weibo (2/3)

Fuda,

Office of the Complex Audit Team,

Xu Mang, as the leader of the group, is also the director of the office, at this time he is proofreading the review list, although the first round of paper review will only start the day after tomorrow, but there is no way... was kicked out by his wife and lay on the sofa all day, which made Yang Xiaoman very annoyed.

After a preliminary check of the list, Xu Mang really found a lot of authoritative figures, of course, according to the questions provided above, in fact, it is not a big problem, it cannot be that there are deviations in some details, or the procedures are not reasonable enough.

However, Xu Mang will not keep an eye on this issue, what he cares about is those improper behaviors that are tampered with and fabricated, of course, check whether there are some academic pseudonyms, and remove names that should not appear, especially some people with special identities.

Others will have scruples, but Xu Mang doesn't care, it's a big deal to fight a fish to die and break the net.

before

Xu Mang has already had a good understanding of this, and the name has long become a chain of interests, some belong to the buying and selling type of name, and the payment fee will help the signature, which belongs to a very low-end existence, and some belong to the glossy type of name, with the help of the celebrity effect, let his article be published as soon as possible.

There is another kind,

Transfer-type notion... I know that my article does not meet the norms or has fraudulent behavior, but I put someone else's name on it to avoid some risks, anyway, there are many types.

In fact, it is very simple to check, but it often affects many people, and at this time a senior person is needed, but the senior ones are unwilling, after all, they have been in this field for so many years, and they have more or less some friendships.

However, young people are not qualified enough to suppress some people... In short, reviewing essay questions is a thankless task, the process is very simple, but the person in charge has to bear a lot of pressure.

It's just too much,

Young but old, the most important thing is that he can ignore a lot of things.

"Hello?"

"Hmm... Okay!" Xu Mang received a call from the second grandfather, and then went to the second grandfather's office.

Push the door in,

Xu Mang saw that his second grandfather was in the office, and asked with a smile: "Second grandfather... Tomorrow I'm going to have a simple meeting with the members, and the day after tomorrow I'm going to have the first round of review, and I'm going to pick up a model. ”

"Hmm!"

"Anyway, you've been reviewed by the list, right?" the second grandfather asked, "Do you feel anything?"

"Alas... See quite a few authoritative figures. Xu Mang shrugged his shoulders and said indifferently: "But it's all a small problem, which can be ignored, but some people's problems are more serious, of course, I haven't read their papers, I don't know how serious it is for the time being, and the remarks are very serious." ”

"Hmm!"

"Actually, you don't need to check, you are the pillar of the whole audit team, just to deter some people. The second grandfather said: "I know you are very busy, so as a last resort, use your own identity to put pressure on the other party." ”

Xu Mang nodded and said seriously: "I know... In other words, are there some second generations in it? Relying on the name to obtain a high education, so as to have a beautiful experience, so as to pave the way for the future life?"

"Pretty much. ”

"There are also many well-known professors who also need you to solve them, and some people will refute you and don't let them have such a chance. The second grandfather said: "Strike hard, this time you must rectify them." ”

"Oh!"

"Don't worry, second grandfather, I'm good at this kind of thing. Xu Mang patted his chest and said with a smile: "By the way, second grandfather, Xiao Man has been a little naughty recently, can you give her a call? ”

"I don't want to deal with the affairs of your little couple. The second grandfather glanced at Xu Mang and said indifferently, "When will you get married?"

"I'll go get my marriage license next month. Xu Mang said seriously: "Marriage... It's not decided for the time being, but it should be two years later, of course, all this is a plan, in fact, it depends on when Xiaoman's belly gets bigger, if there is, the wedding will be done early, otherwise the wedding dress will not be worn. ”

The second grandfather nodded, showed a helpless smile, and said, "Time is too fast... It's been almost 20 years since the little girl in the past was going to get married... Time flies, time flies, and these 20 years feel as if they just happened yesterday. ”

Don't!

Xu Mang also felt that time was too fast, he vaguely remembered that he sat behind Xiao Man, and then said some nonsense to her, and then she became angry, and then a bad relationship was born, the two were like wires inserted into the keyhole, the more they struggled, the tighter they were entangled.

No solution...

This is fate, good things are always impermanent, the opportunity for success and the favor of fate, how many times can you miss it in an ordinary life?

Didn't miss it,

As a result, a violent airfield was harvested.

Back home,

Xu Mang was cooking in the kitchen, at this time he heard the sound of the door opening, Yang Xiaoman returned home, but at this time she seemed to be a little tired, Xu Mang had just finished cutting vegetables, walked to Xiaoman with an apron, and asked with a concerned face: "What's wrong?"

“...”

"There are some things that the company has encountered and I am very annoyed. Yang Xiaoman frowned and said, "I suspect that someone is deliberately manipulating me... Recently, many organizations have been running to my company, either checking this or that, which makes me annoyed. ”

"Huh?"

"Check what?" asked Xu Mang.

"A lot... In short, there is a mess. Yang Xiaoman glanced at Xu Mang, and asked curiously: "Do I want to fight back?"

Xu Mang: (°ー°〃)

I'll go!

Who would dare to mess with you in the magic capital?

Maybe it's a routine inspection, after all, fire and theft prevention measures need to be done.

"Don't be cranky. Xu Mang said helplessly: "It's about to be June, and people have to write a semi-annual report, if they don't check and inspect, who will be responsible in case something happens? ”

"Annoying!"

Yang Xiaoman pouted and said silently: "Anyway, what have you been doing lately? I don't go to work and don't get up until noon." ”

"Check the list. ”

"Look at the names of the people who are going to be reviewed. Xu Mang said: "There is a little pressure... Among them, there are some second generations, celebrities, rich people and the like. ”

Yang Xiaoman said disdainfully: "Cut... What second generation, what star, what rich man, dare to say irresponsible things... Teach him how to behave on the spot, don't panic... If there is a problem, you don't need to explain, just kill them!"

Xu Mang was speechless for a while, this woman is becoming more and more violent, but she is also becoming more and more protective, but this little Mang is really... I really can't listen to it.

"Oops!"

"Can you ban this 'little boundless'?" Xu Mang said angrily: "It's too numb, it's too stupid!"

"Don't!"

Yang Xiaoman's eyes rolled widely, and he said with a smile: "Then I'll call you... Anyway, you choose, Xiao Xuxu or Xiao Xuan, which one you think is good, I will call you, anyway, it is impossible not to call it. ”

I...

This...

It's not good!

After thinking about it, Xu Mang finally decided on the little one in the back.

Dinner is a simple three dishes and one soup, Xu Mang does not make much, two people eat just enough, Xiaoman has been losing weight recently, and he doesn't know what tendons are wrong, he actually stood on the electronic scale, and the number that jumped out almost did not collapse.

But Xu Mang felt that Xiao Man was making a little fuss, wouldn't he have gained three pounds... Is it necessary to make such a fuss? I gained ten pounds before, although I lost it back.

Alas...

I'm going to have a vegetarian diet for a while.

night

Coming again,

Xu Mang had just finished taking a shower, got into the quilt, stood up, took a tablet from his side, and began to tour the latest news.

"Huh?"

"How to solve this problem?" Yang Xiaoman took his mobile phone, leaned over to Xu Mang's side, and asked curiously: "This is what I swiped on Weibo, this blogger said that the above problem has troubled mathematicians for more than a hundred years, can you solve it?"

"Huh?"

"What's the problem?" asked Xu Mang absentmindedly.

"It's a patch issue. ”

"There is a hole in the pants, but the shape of this hole is particularly strange, but the distance between any two points is not more than one centimeter, ask if a round patch with a diameter of one centimeter is really enough?" Yang Xiaoman said: "I calculated... If the hole is an equilateral triangle with a side length of one centimeter, it is basically not enough. ”

"Oh..."

"This problem is known in mathematics as the universal coverage problem. Xu Mang said indifferently: "There are many theories, but the width of the core is one, that is, there is a figure on the plane, and the distance between any two points in the figure is not more than one." ”

"The requirement is to find a graph with the smallest area so that it can cover all shapes with one width. Xu Mang said.

"Huh?"

"Yes, yes, yes!"

The blogger mentioned universal coverage, and he said that no one can solve it. Yang Xiaoman said angrily: "Old lady, I was angry at the time, you didn't start to solve it, he dared to announce that no one can solve it, what do you mean?"

Xu Mang said indifferently: "Using the nature of equal-width curves, the simplest thing is to have a regular hexagon with a distance of one between the sides, and you can achieve universal coverage. ”

Yang Xiaoman was stunned for a moment, and tried to draw a few figures, but the regular hexagon provided by her husband with a distance of one on the opposite side happened to cover all the shapes with a width of one.

"But..."

"Husband... Can it be scaled down a little more?" Yang Xiaoman pouted and asked, "I calculated this figure, and it seems to be 0.866." ”

The blogger said... At present, the smallest universal coverage area is 0.8441153..."Yang Xiaoman said: "Can there be anything smaller than this? He replied to other people's words, and he looked so angry!"

Xu Mang nodded and said expressionlessly, "Yes!"

"You reply to him from the bottom, give me three days to reduce the area to a smaller value than before!"
