Ikawa Academy.

The old man stood under the newspaper corridor with his hand, and he could see that Cheng Yi's cyan Confucian robe had a unique charm, the last time the Qin Dynasty gave a lecture at Lizheng Academy, a green robe was particularly conspicuous, and some of the sharp-eyed martial arts masters saw the difference, and Sima Guang asked the Qin Dynasty at that time.

The Qin Dynasty told Sima Guang about some of the clothing design concepts of later generations, and Cheng Yi, Lu Gongshu, Liu Qin, etc. were all on the side, and naturally kept it in mind, and the green robe on Cheng Yi's body at this moment was an improved Confucian costume.

"If Qin Xian is not arrogant, it is not him. Cheng Yi smiled and looked at the new newspaper in his hand.

"There are three main shocks to me in Mr. Yichuan's article, one of which is that his explanation of Gewu Zhizhi and Li Yifen, especially the redefinition of the meaning of the word 'cheap learning', I am very pleased and convinced, there is no doubt that his understanding of Gewu Zhizhi and Li Yifen is in line with the ...... of the Great Dao"

"There is no doubt that Mr. Yi Chuan's definition of cheap learning is very appropriate, but I want to make it important to say that Confucius did not approve of Fan Xu, which in itself was also Confucius's mistake. ”

Cheng Yi's face was weird, Confucius was wrong?

"Even if Mr. Yi Chuan's definition of 'cheap learning' is very reasonable, but wrong is wrong, where is the mistake, the fault is that Confucius thought that the way of harvesting is a simple way, and any old farmer can easily teach you......"

"The same is farming, our Great Song Dynasty, the previous dynasties before the Great Song Dynasty, are different, if you can see the statistics, on the whole, the harvest of this kind of field has been growing, so in the Confucius era, a hundred and ten acres of land can feed a family, and now a few acres of land can feed a family, what is the reason for this......"

Cheng Yi's face was slightly solemn, although Cheng Yi did not specialize in history like Sima Guang, but he was also full of reading the subset of scriptures and history, and the knowledge hidden in his stomach was massive.

Think about it for a moment.

Warring States period. A family of five needs to cultivate 100 acres of farmland to maintain, even if compared with the Tang and Song dynasties, the yield per mu in the Tang Dynasty was only 1.5 stones, and now 2 stones per mu, one type of cultivated land a year in the Tang Dynasty, and two kinds of cultivated land a year in various parts of the Great Song Dynasty. In some places, there are even three or four kinds of stones, and the highest yield per mu is 6 to 7 stones, which is a big difference.

"This has been the case in all dynasties, and in the country recorded in my "Travels to the Immortal Country", the land planted by one person can be eaten by millions of households, so what?"

"I think this question is worth pondering in our academic circles, and it is not enough to rely on mud legs to study it by themselves......

"A sentence of 'Fan must please learn.' If Confucius had not been ashamed of his crops and had helped the common people to study ways to increase the yield of farming, the Han Dynasty would have been able to have the productive forces of today, instead of a family of hundreds of acres of land to maintain a good life......

Cheng Yi's face was extremely calm, in fact, everyone understood the truth, but everyone turned a blind eye to it before, or turned a blind eye. I didn't take it out, or I didn't have the motivation to study it.

"Young Master Qin. I don't agree with what you say, a scholar goes to the farmland to study, is that still a scholar? Could it be that Qin Gongzi, you will go to the farmland yourself?" asked Ah Zhu.

Cheng Yi had a smile on his face, and it was awkward to let the reader go to the farmland to water fertilizer and apply manure.

"The people take food as the sky, and I, Qin Xianao, want to benefit Lingnan. Naturally, it is impossible not to go to the field, and Qin is working on something called hybrid rice. ”

Hybrid rice?

Cheng Yi's eyes widened, this Qin Xianao was so identious, he was really ...... Really looking into farming?

Cheng Yi's face was extremely solemn.

It doesn't matter if what hybrid rice is useful or not, whether it can be used or not. With Qin Xianao's identity alone, he would really study agricultural affairs in person.

"Terrible, although this Qin Xianao is a demon, such a demon ......"

Cheng Yi took a slight breath, and his gaze continued to fall on the newspaper.

"Qin Gongzi, what is hybrid rice, can you reveal it?"

"You should have read Duan Haifeng's "Origin of Species", which talks about the differences between various species and evolutionary mating, which also contains the truth, pollination, self-pollination, ......

"Qin Gongzi, can you talk a little more popularly. ”

"In layman's terms, people in the south are not afraid of heat and cold, people in the north are afraid of heat and cold, and the children married to southerners and northerners are hybrid, with the advantages of southerners and northerners, and hybrid rice is what it means, and I will write a detailed article about it when I have time. ”

"It seems that it won't be long before we can appreciate Gongzi Qin's masterpiece again, for Mr. Yichuan's masterpiece, Gongzi Qin, please continue. ”

"It can be seen that there are also the principles of heaven and earth in the crops, and these truths are either that I look down on Confucius, or let ten, hundreds, and ten thousand Confucius study together for a lifetime, and I may not be able to understand it, so Confucius looks down on the way of the crops, which is actually very unreasonable......

"So I think that if society wants to develop rapidly, we should abandon the traditional concept of 'cheap learning, expensive learning'......"

"Mr. Yi Chuan did the experiment this time, learned from things, and finally came out of the knowledge, I recognize, and even agree with what Mr. Yi Chuan said, everything about him is flawless, in line with the way of heaven, and can be included in the textbook......"

Cheng Yi's face collapsed, and a smile involuntarily appeared in his eyes.

"Teacher, it seems that this Qin Xianao still has some vision. A voice rang out.

"Originally, it was correct, Qin Xianao was just telling the truth. Cheng Yi smiled, his face flushed, after all, although he Cheng Yi was extremely sure that the truth he had summarized was correct, but outsiders, many scholars in the martial arts world did not think so, and Cheng Yi had also heard of it.

And Qin Xianao.

Qin Xianao's optics can already be used to make telescopes, and Qin Xianao's belief that the earth theory has also been confirmed, so Qin Xianao's recognition is comparable to others' thousands of sentences.

Inside the large yard.

Qin Xianao actually really agreed with the theorem inducted by Uncle Cheng Zheng. Sima Guang glared, and then laughed, "Qin Xianao thinks that the reason for the hemisphere experiment is the pressure of the atmosphere, so this thing should not be very wrong." ”

"Air has weight, and the air on the ground is pressed on the ground, and there is pressure in all directions......" Lu Gong raised his eyebrows, "Even Qin Xianao, the devil, recognizes it so much?" and this Qin Xianao not only recognizes Uncle Zheng's atmospheric pressure, pressure, and buoyancy. Pressure and so on, even his ......"

"Qin Xianao actually praised Cheng Yi's 'no real vacuum', saying that Cheng Yi's reasoning was rigorous and logical, and he really achieved the rigor of learning. Wang Anshi shook his head slightly, "It's unimaginable." Unexpectedly, one day, Qin Xianao and Cheng Yi praised me, I praised you, and they were extremely sure of the doctrines of both sides, but ......'Qin Demon Head' is still a Demon after all!"

After reporting that Qin Xian praised Cheng Yi, he began to pick thorns.

"It's true that Mr. Ikawa's article could be put into the "Physics" textbook, but I don't think it is perfect enough to put it in "Physics" like this. ”

"Qin Gongzi doesn't understand this. You said earlier that his theory was flawless and fit the Dao, what would have happened?"

"The theory is perfect, Qin still thinks so, but for those who do learning, it is not enough to teach to disciples and protégés and make teaching materials. Because he's missing one key thing—mathematization. ”

"Mathematical?" not only Ah Zhu wondered.

Everyone who read this article also stared, and Cheng Yi frowned.

He has been a scholar all his life. In the past few years, the biggest shock, first Qin Xianao advocated the "Tool Theory", to theorems, definitions, strict standardization, Cheng Yi wrote this "everything has quality" article this time, completely according to the "Tool Theory". There are theorems, definitions, and laws, and Qin Xianao actually came to another mathematization.

"A science, only when it successfully uses mathematics, can it reach the point of true perfection, Mr. Ikawa's atmospheric pressure, pressure. Can't buoyancy be digitized?"

"Sounds interesting, why don't you give an example?"

"In my hemispheric experiment, Mr. Ikawa said that it was the pressure of the atmosphere, so he couldn't pull it away, so what is the pressure? What is the atmospheric pressure? Mr. Ikawa talked about the various reasons that affect the pressure, so can these reasons be formulaic? Standardization? The pressure is small, and it is related to the area of force, so how much area will have how much force ......."

"Only when these things are strictly defined, and the numerical calculations and experiments are completely correct, can the real perfect science ......"

Cheng Yi squinted, maybe Qin Xianao's mathematization at the end was a bit picky, but this is indeed a flaw in rigorous study, and Cheng Yi can't deny it.

"Teacher, don't pay attention to Qin Xianao, this person, if you don't pick thorns, it will be the sun that hits the west. You Xing chuckled.

"What Qin Xianao said makes sense, it's not that I can't be mathematized, but the standard, there is no standard, how to measure, if all this is not solved, even Qin Xianao can't be digitized. Cheng Yi sighed and shook his head, and continued to look down.

"Qin Gongzi, your words are indeed very reasonable, but I can hear that if Mr. Yi Chuan's theory wants to be mathematized, it seems that there is a difficulty in it. ”

"You are very smart, indeed, his atmospheric pressure, the pressure must have a standard, just like we measure the distance, we must also use one thing as the standard, and his air pressure is not only a matter of standards, but also a problem of measuring tools......"

Cheng Yi nodded in his heart, in fact, at the beginning, Cheng Yi also thought about how to measure, and he could always use hemispheric experiments as a standard every time.

"Mr. Ikawa wants to incorporate the theory into "Physics", or not, I will help him solve it mathematically. ”

"Help Mr. Yichuan, I don't know Gongzi Qin?"

"Soon I will put it in the newspaper, and I will keep it secret for the time being. At the end of the interview, Cheng Yi raised his eyebrows.

"Teacher, what will Qin Xianao use to measure atmospheric pressure?" You Xing asked, and everyone reading the newspaper was also curious, in addition to doing hemispheric experiments to prove it, what other methods could be used to measure atmospheric pressure? Although everyone could come up with some methods, these methods were not always convenient and comfortable.

Qin Xianao's interview was very unexpected in the martial arts world, of course, this unexpected was not Qin Xianao's madness, if Qin Xianao was not crazy, it would be wrong, and it was not Qin Xianao who directly said that Confucius of the Ten Thousand Worlds was wrong, Qin Xianao could plan the overthrow of the emperor, and how much he respected the sages?

To everyone's shock, Qin Xianao actually surrendered his identity and entered the field with the mud-legged peasants to do the research of 'crops' that Confucius despised, and even said a new term 'hybrid rice'.

A scholar, who doesn't do his job, goes to the field to study farming, what kind of fame can Qin Xianao make?

One by one, they were both weird and funny, waiting to see Qin Xianao's jokes.

And in the end, Qin Xianao actually praised Cheng Yi's theory for being correct and perfect, and everyone thought that since he praised it so much, he would not pick a thorn, but in the end, he still picked a thorn, but this thorn, although everyone was not convinced.

After all, Qin Xianao said, 'All sciences can only reach the point of perfection when he successfully uses mathematics', which is the first time that the entire martial arts world has heard this kind of statement.

"Mathematization is a beautiful idea. Wang Anshi sighed, "I also want everything to be mathematical, how beautiful it is, but don't talk about anything else, just talk about ethics, how do you digitize?"

"Qin Xianao wants to mathematize the atmospheric pressure, in fact, there is no need at all, even if you know how much atmospheric pressure there is in a certain place, what's the use?

"Mathematization, which sounds beautiful, is actually a useless thing. Lu Gong smiled and put down the teaglass.

"Qin Xianao just doesn't want Uncle Zheng to be too proud. Han Zhongyan laughed.

Mathematics is undoubtedly important, but it is only occasionally used in measuring astronomy, geography, farmland, water conservancy, and architecture.

And, can all science really be data-driven?

No one agreed.

Even the most enlightened people.

Although they don't recognize the concept of mathematization of science, everyone is also curious, how will Qin Xianao measure this term 'pressure' that Cheng Yi came up with? )
