Regarding the zone conjecture,

Xu Mang already had a general idea last night, but because he was holding Xiao Man at the time... he didn't put his ideas into action. Now with Xiao Man's support, Xu Mang felt that he could give it a try

, besides... you can also get a Ferrari as a reward.

"Hey hey hey!"

"Your expression is a bit too much!" Yang Xiaoman looked at Xu Mang's tormented look, and instantly became angry, and said angrily: "I'm your wife... Don't you know what your habits are?

You took advantage of me...and you acted like you were at a disadvantage."

"hey-hey..."

"My dear wife!" Xu Mang held Xiao Man in his arms with a smile and said softly: "You are so beautiful!"

"cut!"

"Isn't this nonsense?" Yang Xiaoman rolled her eyes. She didn't care about the eyes of other tourists. She shrank into Xu Mang's arms and said grumpily: "Of course I am beautiful, otherwise how could I be attracted by such a big guy like you?"

The pig's trotters are buckled."

at the same time,

Many tourists noticed Xu Mang and Yang Xiaoman. At the same time, everyone's faces were full of shock. The world is getting more and more crazy. The girl looks like she is seventeen or eighteen years old, but the boy... actually

....What on earth was he thinking?

The day's tour ended quickly. Xu Mang and Xiao Man ate at the hotel restaurant, which was just home-cooked food. However, Xiao Man had a poor appetite because she saw some people's comments during the day.

Browsing Weibo.

"husband?"

"How to refute them?" Yang Xiaoman asked seriously: "I was really pissed off... I was very puzzled. I checked the background of these famous v.s. Good guys... almost none of them are from China.

, all of them are of foreign nationality, and they end up making money from Chinese people here, and they also curse Chinese people, what does it mean?"

"Ouch..."

"This is completely normal." Xu Mang ate black pepper beef tenderloin and said indifferently: "Why bother with them?"

"..."

"Husband...you are so Buddhist all of a sudden!" Yang Xiaoman was stunned for a moment, and said in surprise: "Are you not angry at all? In the past...it would have exploded a long time ago, why doesn't it explode now?

Have you really been smoothed out by society?"

Xu Mang shrugged and said with a wry smile: "I've just encountered too many and I'm used to it... There are still people scolding me on the Internet every day. These people don't see the rise of China. If there is any trouble, they will

I’m very happy.”

"snort!"

"I'm very unhappy!" Yang Xiaoman said angrily: "Don't let me find them, otherwise... I'll make them bankrupt!"

soon,

The couple finished their dinner and then went to their room. Xu Mang used the hotel's paper and pen and sat in front of the table in a daze. Xiaoman was still as usual, sitting on the bed and scrolling through his phone, basically all the time.

Watching Douyin, I laugh like a blind girl.

Sudden,

Xu Mang's cell phone rang, and there was a pleasant ringtone.

"Flickering in that distant time and space, is that mysterious ancient legend. After a long time, it still remains in my heart!"

Yang Xiaoman:???

Well?

This...isn't this a cartoon from childhood?

"Hello?"

"Ah?" Xu Mang said with a confused look on his face: "My child was kidnapped by you?"

The words fell,

Xu Mang looked back at Xiaoman, with a confused expression on his face for a moment, and asked cautiously: "My wife... our child has been kidnapped, what should we do now? The other party asked for a ransom of one million, or else.

..Call the police!”

Yang Xiaoman:(*￣︿￣)

This fool,

If you receive a message from a liar, see how happy he is.

Before long,

The other party transferred two hundred yuan to Xu Mang's Alipay, and then Xu Mang hung up the phone. The whole process shocked Xiao Man. What on earth is going on? With such an IQ, he was

Liar? He deceived the other party in just a few words.

Too,

This big pig hoof is not a good person!

Yang Xiaoman thought of the past, especially in high school... Even though her husband has now changed his ways, he still has the word "bad guy" engraved in his bones.

Within a few seconds,

Xu Mang received a text message from a liar. The content was very simple...it said, you are a liar!

"husband?"

"Is this ringtone of yours the theme song of "Legend of the Gods"?" Yang Xiaoman asked curiously: "Don't tell me yet... I have watched a few episodes... I don't know why I watched it, maybe it's

I was attracted by the theme song.”

"Well..." Xu Mang nodded and said calmly: "I think...technical conditions are never the key factor limiting domestic animation. Take our childhood as an example. The production conditions of this animation are very simple, but

It still makes people’s blood boil after watching it.”

The words fell,

Xu Mang laughed and said, "When I was a kid, I would fight with others every day because of this cartoon."

"..."

"Big idiot!" Yang Xiaoman couldn't understand because he watched the animation, and then imitated the scenes in it, fighting every day... He didn't expect that her husband was also a member of this group.

night falls,

Xu Mang finally put away his mind and began to seriously overcome this level. In fact, this problem seems very simple, but in fact it will be very difficult when you start. First, you need to use discrete geometry, so there is definitely no problem.

The focus of discrete geometry research is on the combined properties of points, lines, circles, polygons and other geometric objects. For example, it will consider how many balls of the same size can be placed around a ball, or how many balls of the same size can be placed around it.

How to arrange circles of the same size on a plane in the densest possible way.

Or how to place the maximum number of balls in space...

Xu Mang discovered that the area problem of the zone conjecture was closely related to some other problems in discrete geometry. One of them was the so-called plank problem, which involves covering the disk with strips composed of parallel lines.

at this time,

Suddenly I realized that this zone conjecture is actually a matryoshka-like problem, which needs to be continuously deduced... to find the original problem.

"husband?"

Yang Xiaoman was wearing pajamas, walked over coquettishly, found a chair and sat down, and said with a smile: "Can you let me participate too? Don't forget... I am an international mathematician.

First place in the competition!”

Not to mention,

Xu Mang was moved... Because there were too many layers of matryoshka dolls in this problem, and he had to solve them one by one. It was really too busy for him. If he had one more helper, it would be almost twice the result with half the effort, and Xiaoman was the best

candidate.

"A bit tired..." Xu Mang frowned and said seriously: "Go and have a rest. Don't tire yourself out."

"no!"

"I must participate!" Yang Xiaoman said seriously: "I will stay here anyway."

"..."

"Okay... help me solve the wooden plank problem." Xu Mang said helplessly: "It's best to prove in a concise way that the sum of the widths of the strips used to cover the circular surface is at least equal to the diameter of the circle.

That is to say, there is no better way to cover the disk than with a plank whose width is equal to the diameter of the circle."

Yang Xiaoman:(#￣～￣#)

asshole!

How can I solve such a professional math problem?

"goodbye!"

The words fell,

Xiaoman returned to his big bed.
