"I understand what Childe said. This Jinghai Palace official school is a pond. A group of blind people want to eat fish, and naturally there are fish in the pond. When the blind man opens his eyes one day and wants to eat dried shrimp, crabs, and turtles, there are actually some in this pond? ”

Liu Yu stroked his palms and laughed: "Those who know me, Zhong Xianye!" That's what it means. ”

The difference between this practical study and the study of the saints lies in how to interpret it, and without the saints there is no study of the saints. And this practical learning can be developed by itself and deduced logically. After learning the first few volumes of geometry, pondering and pondering, the talents of Tianzhong can also ponder the next few volumes. Therefore, this practical learning does not need a teacher like a sage, what is needed is to learn how to think. ”

"A naval officer who has studied a full set of mechanics and geometric calculus will be able to calculate more than ever before after retiring. Perhaps, if we set up an academy of sciences, the first native academician of this academy will be a retired naval officer. ”

Kang Buxian thought about what Liu Yu had said before, and asked, "Didn't Your Majesty also say that there is an idea of establishing an academy of sciences?" ”

These words made Liu Yu couldn't help laughing.

"That's right. But when Euler came, who could understand what he was saying? How many people can discuss the three-body problem and the orbit of the moon with the country at this time? Therefore, it is necessary to set up a practical school to ensure that when there is civil strife in the palace of the Rakshasa Kingdom, these people are called over, and someone can understand. ”

"There is only a sir, but there are no disciples, and it makes no sense to ask him to teach algebra arithmetic."

Kang Buxian naturally doesn't understand what the three-body problem is, but he probably understands what Liu Yu is going to do.

In the name of revitalizing the navy, in fact, what is to be promoted is practical learning.

Thinking that Liu Yu was worried that he would not be able to get enough money, Kang Buxian said with relief: "Son, you can rest assured." The money should be available. Does Childe know what Su Dongpo said about Wei Qing back then? A slave like Wei Qing is also suitable for licking hemorrhoids. Born in the Wude Palace, in the eyes of the courtiers, he is also a fortunate minister and a slave like Wei Qing, His Majesty has to maintain it, and it is His Majesty who bears the infamy. As long as Your Majesty has a heart, this matter will definitely be done without the presence of the son. ”

It sounds like an insult, but it's actually a relief.

Liu Yu's mood relaxed slightly, and he laughed: "Maybe." It's just that when he is an emperor, no one wants to bear the reputation of a brutal Emperor Wu of the Han Dynasty. Everyone wants to be Song Renzong, no one wants to be the Qin Emperor and Han Wu. By the way, I asked the French to bring me the books before, did they bring them? ”

A few years ago, when the French delivered the warship, Liu Yu spent a lot of money and asked the French to bring a few very important books.

Kang Buxian doesn't know Latin, he can only know a few words, but he knows that Liu Yu values these books very much, at least more than the training of the Qingzhou Army.

"Brought. I've been keeping it carefully. ”

Back in the room, from a locked cabinet, Kang Buxian took out a copy of the third edition of "Mathematical Principles of Natural Philosophy" published in 1725, two years before Newton's death, a thick book, about six or seven hundred pages.

Liu Yu asked Kang not to slack off, if these books arrived, he might find someone to try to translate them.

Xu Guangqi said that if you want to be able to understand, you must first translate.

It's just that these books are too difficult to translate.

"Childe, I've often heard you talk about this book. I've heard you say that a lot of the content in this book has been taught to others. Like, force, inertia, and things like that. Childe has already included the synopsis, do you still want to finish translating the book now? ”

Flipped the heavy book in his hand, turned a page casually, and looked at the geometric figures and various extension lines inside, Liu Yuxin said that he was afraid that he was also reading this book for the first time.

"Know what it is, know why it is. It's not the same thing. If you just know it, you can just learn the outlines I wrote. But to understand why, it's best to see how this Newton reasoned. ”

Turning to the title page, the first page is Halley's preface to the book.

"Look at the layout of the sky, the balance of sacred matter."

"Look at Jupiter's calculations, and the rules of the Creator."

"He made the rules when he created all things."

"After it is formulated, even he will not violate it, which is the basis of his work."

"The sun sits on a throne and commands all things to descend on him, but the celestial bodies do not run in a straight line."

"From this book we finally know the reason why the bright moon god is moving forward with unequal steps; From this book, we also know how hard the roaming Diana pushed the tide to recede, leaving seaweed and shells behind the tired seaweed......"

Trying to translate the preface poem made by Halley for Newton, Kang Buxian listened for a while and said with a smile: "Let me guess, is this Diana similar to Wangshu in our story?" Chang'e? The tide is because of the moon, isn't it? What does Childe mean, let me polish it? ”

Liu Yu's translation has neither plain nor rhythmic rules, and it is completely vernacular. After such a book is printed, I am afraid that cultural people will not take a second look.

But the reason why Liu Yu asked Kang Buslack to help was not this.

"Polishing is to polish, but the main thing is to replace Jupiter, Diana, or something with gods that ordinary people can understand. There are also things like "He made rules when he created all things, and after they were made, even he would not violate them, which is the basis of his work", and I would use words such as "Tao" and "Li" to make a difference. ”

Judging from this sentence alone, Kang Buxian feels that this is not difficult. But if you want to turn the book, you need to set a tone first.

"It's not difficult for Childe to ask me to polish it. The difficult thing is what is the tone of the childe? ”

"Well, the tone is to translate the preface and make a new preface. You will find a way to lean in the direction of the Yongjia School's 'where things are, and the Tao is in Yan'. This book is to explain why the moon turns like that, why the stars don't fall, and why the water goes down. It's just a truth, there is no emotion such as water is good. ”

Kang Buxian understood, and probably understood what Liu Yu meant.

"Childe, is this book so important? You definitely don't have time, the point is that after I get this book, I'm going to find someone who knows a little bit of knowledge and understands some Latin, and try to translate it, but ...... They simply don't understand. ”

"Can't understand?"

Liu Yu was a little stunned, he hadn't actually read this book, but he had just heard more about it.

Turning the title page and the preface in front, I turned to the first chapter, and after reading it for a while, Liu Yu himself was confused.

The first chapter of the opening chapter deals with the concepts of limits, differentiation, and tangents of curves in geometric concepts.

Because when this book was written, calculus had not yet taken shape, but the content in it had to use limits, tangents, geometry, conic curves, etc.

After reading it for a while, Liu Yu rubbed his head, and said in his heart that even if this book is printed, it will not lead any trend, because he has a headache when he reads the first chapter of the first article, but it is conceivable that even if this book is printed, it will be like a book from heaven.

This is not to say that the mythical Newton was ahead of his time, but because he was personally ahead of the times, and the mathematical tools he used were still old, and he geniused to solve the content of calculus with the knowledge of the old era, and this obscurity is really indescribable.

I thought this book was about mechanics and gravity, but just now I was still talking to Kang Buslack there, knowing what it is, knowing why it is.

After I really saw it, I thought about it for a while and couldn't help laughing.

This book...... Now that it's translated, it's true that the eggs are useless.

"Come on, I don't want to translate this book for the time being. I think it's simple. It's not useless to translate, but to have the energy to translate this book, it's far better to do something else. The rate of return is too low. ”

Xu Guangqi said that if you want to understand, you must first translate. I don't think it's appropriate to use it at this time. If you want to get through, start anew. ”

"From an early age, let them learn what they have learned, they don't need to know why it is, just know what it is. Don't follow the path of Westerners. Whoever learns it in the future will translate it. ”

Throwing aside the mathematical principles of this book of natural philosophy, rubbing his head that felt a little headache after reading it for a while, thinking about it, he felt that the route of the compulsory education textbook in the previous life was the most suitable for the current Dashun.

Don't talk about the mathematical principles of natural philosophy, just let more people know that the earth is round and gravity is common sense.

Don't talk about any profound way of thinking, as long as enough people learn these things first, there will naturally be more advanced learning to explore deeper content.

I thought I was going to try to take the route of "learning from the West to the East", but after turning a few pages of the book, Liu Yu had completely given up this idea.

Technology can be learned from the West to the East, copied if it can be copied, and translated if it can be translated.

Science will gradually learn from the West to the East, and it will gradually take place in a hundred years.

Even if the book is translated and thrown to Jiangnan, it won't be able to make a splash.

It is often felt that if these books are translated, they will be able to get rid of backwardness. But now it seems that it is really unlikely.

The first chapter can dissuade the vast majority of scholars, because if you want to understand the first chapter, you have to make up geometry, conic curves, and limits, and learning these things is extremely time-consuming, and the imperial examination is not examined, so I am afraid that this book can be circulated in a small circle.

This is not surprising, it is Yau Chengtong, who won the Fields Medal, also said that Newton's book is too difficult to understand and it is a headache to read.

Geometry was originally something that was nearly 2,000 years ago, and it is okay to use this Western study to gradually move eastward.

But it is gradually deeper, and the imperial examination is not examined, and no one can learn so deeply.

With new knowledge, it is better not to engage in any Western learning and to start anew.

It is much easier for some people to accept a new world view in a closed environment since childhood, than it is to let scholars and doctors transform themselves in a closed environment.

Originally, Liu Yu had such an idea, and after reading Newton's book, he made up his mind even more firmly.

After thinking for a moment, I picked up my pen and spent three or four days in my room, writing something.

After finishing writing, he handed it to Kang Buxian and said, "Brother Zhongxian, you shouldn't have been exposed to this knowledge before. But just these few pages, do you think you can understand them? ”

Curiously took the few pieces of paper, Kang Bu silently read the content on it, it was indeed unprecedented learning.

“…… Everything is made up of atoms...... A large ball is the nucleus of an atom, and the small ball on the outside is called a pip, just like the moon revolving around the earth......"

After reading it carefully, Kang Buxian nodded and said, "This can be read, and I can probably understand it." Although I don't know if it's true or not, if I learn it this way since I was a child, I will think that this is a heavenly principle and cannot be changed when I grow up. If they have been studying since childhood, after they have completed their studies, there is no other way to impress them and make them change their minds. ”

"Childe, is this going to learn from Bai Lotte? Every time you make a new poem, you must read it to the ignorant old woman first? ”
