Bo Xiaofeng slammed his face against the wall, and he had a feeling of being shameless in front of his ancestors.

Girl, girl...... You also ......

"Tsk, your sister is really a genius!" At this moment, a voice sounded extremely unflat.

Bo Xiaofeng wanted to cry and looked at Su Junyu who came over with bad intentions: "If you want to fight, let's find a place to do it now." ”

Su Junyu waved his hand: "No, no, no, I'm sincere." We're all arithmetic, and you should know how much this kind of persistence will help her, right?"

Bo Xiaofeng slammed his head against the wall on the side twice, before looking at Su Junyu: "Indeed." My sister, when she's not thinking about arithmetic, she's just an ordinary child, and at most a little arrogant......"

"That's how it is when it comes to arithmetic. Su Junyu looked at the ring: "I thought my little brother was not good this time." Now it seems that the opponent is your sister, no problem!"

Bo Xiaofeng was furious: "What are you talking about!"

Su Junyu Nunu mouthed: "See for yourself." ”

The form on the field is developing in a direction that people don't understand.

Faced with a certain tendon problem, Wang Qi thought about it and replied seriously: "This seems to involve a very complicated arithmetic problem. ”

Bo Xiaoya nodded: "Indeed, logically speaking......"

Wang Qi shook his head: "No, we can go a little deeper-have you ever studied set theory?"

Bo Xiaoya nodded as if she didn't understand. She hasn't understood the relationship between this and set theory.

In mathematics, sets and logic are very close to each other. Set is the foundation of mathematical language, logic is the only tool for mathematical research, both are the most basic parts of mathematics, and they are the foundation of mathematics. A logical problem will also involve an arithmetic problem.

But...... What is the definition of "above board"? Does this seem to be closer to a play on words?

Looking at Bo Xiaoya, who showed a puzzled expression, Wang Qi was happy in his heart,

Whahaha

Although he was about to laugh in his heart, Wang Qi was still very calm on the surface. He gathered a trace of mana, cut off one of his hair, and asked, "Miss Bo, please see, I cut off one of my own hair." ”

Bo Xiaoya's attitude was not very friendly: "I will see it myself." ”

Wang Qi was unimpressed: "If I keep cutting it, can I count it as bald when I cut it?"

"Huh?" Bo Xiaoya's eyes widened and she was asked, "What is the specific definition of the concept of 'baldness' in this ......?

Wang Qi shook his head: "There is only one definition of 'bald'. ”

Bo Xiaoya shook her head in confusion: "I don't know." ”

Wang Qi continued to ask, "If I were to build a collection called 'Bald', how many people in Shenzhou would be counted as elements in this collection?"

"Can something that isn't clearly defined be a collection?" Bo Xiaoya put down the long sword in her hand and continued to ask rhetorically.

At this moment, Bo Xiaoya actually came into contact with a qiē defense! Theoretically, Wang Qi had a high chance of defeating her by launching a surprise attack. But will Wang Qi do that?

Now, hey, hey, of course not!

"Why not. In order to show sincerity, Wang Qi also put away his sword: "You know, the definition of a set is 'a collection refers to a collective of concrete or abstract objects with a certain nature', and the concept of 'bald' does not conform to the four words 'certain nature'?"

Bo Xiaoya shook her head in confusion. The question is somewhat difficult to understand.

How can such an ambiguous thing be calculated?

Wang Qi sat on the ground and said, "Sit, in fact, we can discuss this issue." ”

Bo Xiaoya sat down across from him stupidly: "Discuss...... What?"

Wang Qi pointed to the sky and the ground: "Actually, there are still many such unclear definitions in this world. ”

Bo Xiaoya said suspiciously: "You point above and below...... Does it have anything to do with life?"

"Ahem, don't care about these details anymore, you see, we're all talking about this ambiguity, why should you care about the details?"

The girl nodded: "Oh too." ”

Wang Qi cleared his throat and said, "Where are we talking about? Oh yes, in fact, we will encounter a lot of concepts that do not have a clear boundary, such as 'a pile of sand', one grain of sand cannot be counted as a pile, and two grains cannot be counted, so at least how many grains of sand can be counted as a pile? What is beauty? What is ugliness? Can this be quantified? How can it be quantified? Miss Bo, how many points do you think you can score for your appearance?"

"Hmm......"

Wang Qi's series of questions made Bo Xiaoya a little dizzy, and it was the first time she thought about such "non-rigorous" questions as thinking about the attitude of arithmetic. After a while, she said, "These seem to be artificially defined." Can this be considered a false proposition?"

Wang Qi shook his head: "Miss, do you think that your brain is not composed of elementary particles and is not aggregated by the four spirits of the Open Heavens?

Bo Xiaoya shook her head honestly.

"The human heart is the function of the thinking organ. The organ of thinking is a product of nature and the embodiment of the Tao, so why should the concepts conceived by the human mind be excluded from the concepts of nature?"

The children of the Bo family were silent.

Then, the audience was in an uproar.

"What is that guy talking about?"

"How did you start talking about the Tao?"

"Is this a delaying tactic?"

And Su Junyu and Bo Xiaofeng's faces have changed.

The question Wang Qi asked was not something pretentious, let alone a play on words. What he is talking about is one of the most important mathematical achievements of the earth in the mid-twentieth century - fuzzy mathematics.

In many people's minds, mathematics must be rigorous and precise, and there is no room for any difference. Even a fractional point error can result in a "thousand miles of error".

However, in truly advanced mathematics, even "uncertain", "inaccurate" and "not rigorous" can be axiomatized to you.

Fuzzy mathematics, chaotic mathematics is the proof that mathematics has stepped into that uncertain world.

"So. Wang Qi laughed very evilly: "Let's start with logic and discuss this issue carefully!"

So I can drag it out as long as I want, whahahaha!
