The road to technology

Chapter 342 Completely different from what I imagined
Why?One plus one is equal to two, this is obvious, how can there be why.

Everyone in Yuqing Hall was a little confused at this moment.

Especially Cangsong, Yuyangzi, and Shuiyue who has a bad temper. Their faces changed slightly, and they seemed to be angry. If they didn't know that they couldn't beat them, they would all rush forward to beat Yue Yuanzhou this time!
How could anyone entertain them with such questions?
At this moment, Tian Buyi couldn't bear it anymore, he stepped forward and said loudly: "This is the case in the world, so why not!"

Tian Buyi continued: "If you want to say that one plus one does not equal two, I also know that a pile of rice plus a pile of rice is still a pile of rice. A drop of water plus half a drop of water is still a drop of water."

After finishing speaking, Tian Buyi waited as if waiting for Yue Yuanzhou's denial, but what he didn't expect was that Yue Yuanzhou didn't say he was wrong: "Yes, this idea is very good, daring to think, daring to speak is a part of learning science." important factor."

This is the most basic question, of course Yue Yuanzhou won't talk about advanced Goldbach's conjecture and the like.

实际上陈景润证明的是任何大于2的偶数都能表述为一个质数和一个质因数不超过两个的数的和。记作1+2。好似距离1+1只有一步之遥，这个故事被人以讹传讹就变成了陈景润证明了1+1=2这种让人啼笑皆非的谣言。

So what Yue Yuanzhou is talking about now is indeed the most basic introduction to mathematics.

"Senior, please make it clear!" Tian Buyi cupped his hands, heaving a sigh of relief, finally he was not ashamed.

Yue Yuanzhou didn't continue to play tricks, he just asked these people to think about it, the purpose was to let them have a deeper impression of what he said next.

"Actually, you have all learned numerology, it is just the simplest addition operation, it is so taken for granted that when you use it, you take it for granted."

Everyone nodded, and they really hadn't thought about this kind of problem before.After all, putting two stones together is not two stones. This is the answer given by nature. There is no reason.But today someone told them why, how could it not make them wonder.

At this time, Yue Yuanzhou continued: "I believe you have heard clearly what the head of the Big Bamboo Peak said just now. This is a matter of definition. If the definition is not clear, one plus one will have different answers. To understand this question, one First of all, we need to define, the so-called one plus one equals two is the definition of two.”

"Firstly, it is stipulated that 1 is a natural number. Second, it is stipulated that the successor of any natural number is also a natural number. But in order to avoid the fact that a pile of meters plus a pile of meters is equal to a pile of meters, we must also stipulate the third rule that 1 is not a natural number. Successor. Then stipulate the fourth article: Different natural numbers have different successors."

"However, in order to avoid the problem of a pile of rice plus a half pile of rice that Tian Buyi said just now, we have to stipulate the fifth article at the end. If a certain property is given to a certain natural number, the successor of this natural number can also have this property. If 1 does have this property, then all natural numbers will have this property."

Yue Yuanzhou said self-consciously: "The last one is mathematical induction, which is the most commonly used method of mathematical proof, and it is also something that must be understood on the road to science. Mathematics is a tool of science. So you have figured out these five, You will know why one plus one equals two. After that, you can start your career in science.”

"Of course, mathematical induction also has its limitations, but it is too early for you at this stage. For example, mathematical induction cannot be used to prove the monotonicity of continuous functions."

After finishing speaking, Yue Yuanzhou displayed the five Piano arithmetic kilometers on the projection screen, then looked around at the crowd with different expressions, and said, "Have you ever understood?"

"what?"

"No here."

With Yue Yuanzhou's reminder, everyone in the Yuqing Palace looked at him in bewilderment, as if they were saying: Who am I?Where am I?What am I going to do?
What natural number?What successor. What mathematical induction.


At this moment, Tian Buyi poked Daoxuan who was standing in front of him quietly: "Brother sect master, do you understand?"

Hearing this, Daoxuan immediately put away his somewhat confused face, showed a confident look, cleared his throat and said, "Of course I understand, it is indeed the method of getting started in the Dao of Science, it is really exquisite."

Tian Buyi who was standing behind Daoxuan naturally couldn't see Daoxuan's confused face just now, he really thought that Daoxuan understood.

He secretly said: As expected of being the leader, I understood it all at once. I just thought about it for a while before I realized that it was a matter of definition.

It's just that there is such a complicated definition at the beginning, isn't it more complicated later?It seems that no matter what kind of Dao's longevity method is full of difficulties.

At this time, Tian Buyi saw that Cangsong was still in a daze from the corner of his eyes, and couldn't help teasing loudly: "Senior Brother Cangsong, you must have understood such a simple introduction, right?"

"Eh? Oh, it's Junior Brother Tian!" Cang Song Rumeng woke up startled, and then revealed a confident look on his face as Daoxuan glanced at just now, and said proudly: "That's natural, this scientific way is really a way of longevity, I didn't expect it to be possible. To analyze such a common problem so thoroughly, it really leads directly to the essence!"

And Jin Ping'er, who was dressed in red, said that it would be better for her to go back to embroider, as Jinxiufang's business has been good recently.

"It's still like this, these thoughts are too strict." Zeng Shushu's eyes changed from confusion to curiosity. He really didn't expect that a question that should be taken for granted could be analyzed so many ways.

"It turned out to be like this!" Wan Wanqian murmured, and took a deep breath. He knew that this was really an introduction!Because he listened very carefully just now, he could understand the following sentence 'mathematical induction cannot be used to prove the monotonicity of a continuous function', but he didn't understand what it meant.

Yuyangzi, who heard thousands of people whispering, approached quietly: "King of Ghosts, can you explain in detail?"

Thousands of people go: "..."

It also explained in detail that people often think that they should study the heavenly scriptures seriously later.After all, this is completely different from what I imagined. It's not a great way to hear the sound of the sky.

But since this is what people said clearly, it must be a very profound way if he can't understand it, so he concluded that this is the beginning.

In fact, it's not that other people don't understand at all, that is Wan Jianyi.But what he understands is not mathematics itself, but the reason behind it, that is, Tao is everywhere.

At this time, Wan Jianyi's eyes suddenly became clear, and his breath began to change faintly: "It's extremely, it's extremely! It's really enlightening."

There is only one sentence echoing in Wan Jianyi's mind now, and that is: The Tao is drowning in feces.

He remembered a passage in "Zhuangzi's Journey to the North": "Dong Guozi asked Zhuangzi: 'The so-called Tao, is it evil?" 'In the ants.' Said: 'How can I get down?' Said: 'In the barnyard grass.' ... Said: 'How much worse?' Said: 'Drowned in feces.' Dong Guozi should not."

The translation is.Dong Guozi asked Zhuangzi, "Where does the Tao that people talk about exist?" Zhuangzi said, "The Tao is everywhere. ’ Dong Guozi said: ‘It is necessary to point out the specific place where it exists. ’ Zhuangzi said: ‘Among the ants. ’ Dong Guozi said: ‘Why are you in such a humble place?’ Zhuangzi said: ‘In the barnyard grass of the rice field. ’ Dong Guozi said: ‘Why is it getting lower and lower?’ Zhuangzi said: ‘Among the tiles and bricks. ’ Dong Guozi said: ‘Why is it getting lower and lower?’ Zhuangzi said: ‘In the urine. Dong Guozi didn't say anything after hearing this.
