Extraordinary understanding: from mathematical emperor to civilized leader

Li Qifeng felt that what Xu Ning said was a little strange, but he still led him to a specialty store in the mall to buy him three sets of almost white sportswear.

It added up to about 30,000, which is naturally not much for Li Qifeng, but it is indeed a big deal for the audience and Xu Ning.

——[Li Qifeng this person is still very good, no wonder he can run a company worth hundreds of millions, when it is time to do favors, even for an ordinary teenager with appropriate respect, I like him! ] ]

——[Li Qifeng belongs to the kind of person with high emotional intelligence, he spent so much money, not only took care of the face of Xu Ning and the program group, but also put a small advertisement on himself and the company, he is generous, for a teenager who can be said to be a stranger, let alone his partners. ]

——[Sure enough, no one's success is purely lucky, they are all very good in some aspects, Li Yifeng's IQ and EQ are obviously good, but I think his wife feels a little difficult to talk to, I don't know what kind of vision he is. ]

——[Don't talk about his wife, Li Qifeng was able to come out mainly by relying on a inheritance left to him by his father-in-law, otherwise do you really think he can make a lot of money so easily?] ]

——[I don't understand why you are all talking about Li Qifeng, shouldn't you be curious about Xu Ning, the clothes that add up to almost 30,000 yuan, he didn't even touch anything, and accepted it very normally, as if he had cut a lollipop from the teacher's hand, so logically. ]

The audience in the live broadcast room talked a lot, and Li Qifeng was also surprised by Xu Ning.

He originally thought that if he bought clothes for Xu Ning, Xu Ning would be busy refusing, and then accept it half-pushed.

This is also normal, many people in the world are like this, just like when the New Year is over, when facing relatives to send red envelopes, they always have to half-push and half-push, so as to appear a little sincere.

Show the state that I want, but I shouldn't and can't want.

However, Xu Ning was not like this, he didn't seem to pay attention to these clothes.

For him, clothes are just clothes, the most important thing is to be able to wear them on his body to protect himself from the cold, and everything else has added value.

'What a weird kid...'

Li Qifeng muttered secretly in his heart.

After buying clothes, Li Jifeng took Xu Ning to a nearby hotel for a meal before returning to his home.

After returning home, Xu Ning, who had not spoken much, finally spoke, "Uncle, are there any books to read here, especially related to mathematics?" "

Li Qifeng said angrily: "Needless to say, please, it's too polite, you just treat yourself as if you were in your own home."

As for the books, they are all in the study, but I bought them and put them there without reading much, and I forgot what types of books I have, you can flip through them yourself. "

Xu Ning nodded and went straight to the study.

Pushing open the door, Xu Ning found that the study room was not large, about ten square meters, but several bookshelves were full of books.

At a glance, there are all kinds of books, mainly related to economics and finance, followed by some historical masterpieces and monographs.

Xu Ning searched around and found a copy of "Classical Mathematical Conjectures" on the bottom of the bookshelf.

Taking the book out of the shelf, Xu Ning sat on a chair, spread out the book and read it quietly.

The book mentions many conjectures that have appeared in the history of mathematics, but most of them have already been proven, and are placed here mainly to expand the reader's knowledge.

Xu Ning turned page by page, and his brain was like a U disk, constantly storing all kinds of knowledge.

Finally.

He stopped, his gaze falling on the "Sitapan conjecture."

The book briefly introduces the Sitapan conjecture:

It is a conjecture in the field of mathematics about the strength of the proof of Ramsey's two-staining theorem.

In combinatorics , Ramsey's theorem solves the following problem : to find such a minimum number n , such that n people must know each other or l people must know each other.

Many mathematicians have tried to prove or falsify this mathematical conjecture, but they have failed.

One of the famous mathematicians commented that Ramsey's number was unattainable.

He gave the analogy of saying that if an army of aliens were to land on Blue Star, they would demand that we must obtain the value of Ramsey number R (5,5) or destroy Blue Star.

At this extreme, Blue Star should concentrate all the computer and mathematician efforts to find this Ramsey number.

But if the alien army requires the value of Ramsey number R (6,6), then all mankind on the blue star should do its best to develop its own military power and fight to the death against the aliens!

This shows how difficult it is to find Ramsey numbers.

Well, if that's not clear enough, describe the Sitapan conjecture with a simple example.

That's the friendship theorem:

In a group of no less than three people, if two people match arbitrarily, both happen to have one person in common, there will always be such a person in the group who is known to the rest of the group.

Transferring this theory to a logic graph , if each vertex in a logic graph happens to have one and only one adjacent vertex in common with the rest of the vertices , then there will always be one vertex in the logic graph adjacent to the other remaining vertices.

It is such an ingenious theory of logical mathematics, but it has puzzled the logical mathematics community for decades.

But at this moment, the logical order of this conjecture did not hesitate to unfold almost all the secrets in front of Xu Ning!
