Dafang looked at this kid who had been trying to be equal to himself in his heart, and even this white man may not have realized his own thoughts, this desire to be recognized can only prove that he is still just a child.

In the face of children's innocence and simplicity, Dafang has always been very patient.

Looking at Dafang and smiling slightly, Bai Ying couldn't help but cheer up, he knew that the exchange of equals was finally about to start.

"If I can answer it for you, will you teach them for me?" Generously raised his eyebrows.

"Of course, it's a deal!" Fairy is very proud.

"But, you have to convince me!" Bai Bai added again, he didn't think that the old monster could analyze this problem and convince himself.

Dafang looked at the proud boy and said, "Yes, but I need to tell you in advance, I don't like children who cheat, if I think you're cheating, I'll let you know what a ruler is." ”

Bai Haoyao didn't understand what the ruler was, and he said without hesitation: "I never regret it." ”

Nodding generously, he said, "This problem contains the fundamental concept of mathematics, so this is actually a conceptual problem, and once you are not careful, it is easy to fall into a loop." ”

"Do you know what math really is?" Dafang immediately asked his own question.

Bai Hao, who had just received equal treatment, did not hesitate at all, and replied directly: "Quantity calculation, reasoning, logic." ”

Suddenly realizing that his identity began to slip down because of answering the question, he immediately added loudly: "But you can't say, facts don't need reasoning, first you have to prove 1+1=2, and then 1+1=2 to count the facts!"

The smart white immediately plugged the loopholes he could think of.

Dafang's quick reaction to the white white, but smiled, and said, "Your statement is half right." ”

Bai looked at Dafang in surprise and said loudly: "Impossible! All the known civilizations in the universe, countless trillion lifeforms, agree with this! ”

"So, is the number right or not?" Dafang immediately asked rhetorically.

Bai Ai was speechless for a moment, unable to find any words to fight back.

"And, in fact, it's not as you say, that countless trillion beings agree, at least the real mathematicians in the human race, disdain the second half of the sentence, and many of the seemingly extremely stupid races in the universe also completely disagree with this arrogant view, and nonsense will not bring real victory, remember that." Dafang said unpleasantly.

"And what do you say?" Bai Ai immediately widened his eyes and asked loudly.

Dafang glanced at him and said, "Are you asking me for advice?" ”

When Bai Bai heard this, he immediately turned his head and stiffened his neck, and after a long time, he seemed to have made great efforts to calm the blood rushing to his head, and then, with an aggrieved tone, he lowered his head and said in a voice that was so light that it was almost inaudible: "Please teach the teacher"

"Heh, mosquitoes are louder than you." Dafang laughed.

Bai Hao was very unhappy, and he made up his mind that he would never repeat the extremely humiliating words just now.

"In fact, there are many people who claim that logic can solve all mathematical problems, and most of the people who make such ideas are very intelligent people, just as smart as you are, and very conceited. So have you ever thought that while you come to this conclusion yourself, your ego has the possibility of turning into arrogance and arrogance? In other words, the person who came to this conclusion was actually his arrogance and arrogance who played a leading role. Dafang asked again.

Bai Haohao disagreed, saying: "This is a serious question, you can't question it with this uncertain assumption, you should tell me what's wrong?". ”

"In fact, as I told you at the beginning, it's really a matter of concept, and the difference in concept is in the word 'mathematics'."

Dafang continued: "You claim that mathematics is also logic, so do you know what logic is? ”

Bai Haocai thought for a moment and said, "A method of summarizing and reversely deriving the causes, processes, and purposes of life behavior. ”

Dafang immediately praised: "Very good answer, I think you should be rewarded." ”

After speaking, he took out a small chip and shook it in front of his eyes, and said, "How is it?" Eight-year-old version. ”

Bai Hao seemed to be immune to this, and he was extremely satisfied with his summary, and proudly refused on the spot: "Don't, don't treat me as a child!" ”

Dafang put away the chip when he heard this, and said: "I am personally accustomed to calling logic the trajectory of all life behaviors. ”

Bai was stunned for a few seconds, and nodded silently, this description is indeed more concise than his own, and the summary is clearer.

'This old guy is really very annoying, what is it to bully children, when I am as old as you, I will throw you out of 108,000 miles! 'Not as white as a child, my heart is quite depressed.

Ignoring the white thoughts, he immediately asked, "So, is mathematics an act of life?" ”

"Of course!" There was no delay in the white counterattack.

Dafang smiled happily when he heard this, and immediately raised the second question.

"So tell me, is there the number first, or the life?"

With his eyes wide open and motionless, he froze.

Similar to the problem of eggs and hens, so that Bai Hao couldn't help but lose his voice, but Bai Hao's intelligence is extraordinary, or superhuman, he thought for a while, frowned and said: "'Number' is an objective existence, and 'quantity' is the summary of life to 'number', so there is 'number' first, then there is life, and then there is 'quantity', so the number calculation of mathematics is still the act of life." ”

Dafang was overjoyed after hearing this, and praised him without hesitation: "You are really very smart, do you want to be my student?" You can't find a better teacher than me. ”

"I don't want to!" Bai Bai tilted his head to the side, he resolutely refused to admit that this nasty guy was better than himself.

Dafang was not disappointed, and then said: "You are right, quantity calculation is an act of life, so you can use logic to solve it, but don't forget, you yourself said, 'number' itself is objective, whether there is life or not, 'number' is there, so don't you think that the 'number' itself is insignificant life, to summarize 'number', is it too arrogant and subjective?" ”

"How can this be considered arrogance? As far as I know, all human science and technology are inseparable from mathematics, and without this kind of 'subjective arrogance' you said, you would not be where you are today! Bai Bai retorted loudly, and the tone of his words was so sonorous and fierce that there was no way to add anything other than jumping up himself.

The accusation that was almost spitting did not make Dafang angry, but nodded and said: "You are right, but is this contradictory to subjective arrogance?" ”

Bai was stunned.

Looking at the whiteness who didn't know how to refute, he smiled generously and said: "In fact, subjective arrogance is one of the sources of human progress, which does not need to be criticized, but there is no doubt that subjective arrogance has limitations and is relatively narrow. ”

"So the 'mathematics' that arises from 'subjective arrogance' is also narrow." After speaking generously, he quietly looked at the white sky.

Bai Hao, who was almost subversive of the three views, argued fiercely: "You are strong words, you are narrow-minded!" ”

Dafang said coldly: "Those who are justified and take the initiative to attack are always the ones with weak thinking, with few exceptions." ”

"You're saying I'm a strong word? Then answer me first, what is the essence of mathematics? Dafang asked.

"Addition." White, without thinking.

"Well, that's good. So now, try to prove it with explicit quantities and additions, and show me infinite numbers. ”

"How is this possible!" White screamed.

"If you can't do it, isn't it narrow-minded?" Smile generously.

"What kind of ability is strong words!" Bai Haoyao was very unconvinced, and then he thought of something and shouted: "You are asking me my question!" What's the difference between this of you and what your mother said about Goldbach's conjecture! ”

"Absolutely." Dafang is extremely calm.

Bai Haoyao looked disdainful, obviously thinking that generosity and strong words should be reasonable.

"The difference is that I know the narrowness of mathematics, and those who are committed to Goldbach's conjecture are mostly unaware of it," said Dafang. ”

"This is a common problem of most three-dimensional life, and it is impossible to prove Goldbach's conjecture within three dimensions alone, because this conjecture is no different from trying to interpret infinite numbers with explicit numbers and additions."

"If we jump out of the three-dimensional and make the three-dimensional infinite number truly explicit, this problem confined to three dimensions can be solved."

Bai Hao fell into thought again, and after a while, he suddenly smiled again: "Then can you prove that 1+1=2 now?" If you can't prove it, you won't be able to answer this question for me, which means you don't know why 1+1 equals 2, do you? ”

Bai Wai began to be proud again: this guy really couldn't answer, and was almost surrounded by him, the old guy was ghostly, hum.

"I can answer it for you, so would you like to hear it?" The old guy showed his white teeth again.

Bai Bai, who had made up his mind not to repeat that humiliating sentence before, looked up at the hateful old face, and the blood began to rush to his head again, and after a long time, he had to say again, with an extremely aggrieved tone, and dragged in a tone of Lai Pi, which was both vague and extremely fast: "Cen Laosi's teachings"
