On the first day after completing the training of Xun Wei etiquette, Liu Yu met a few acquaintances before he handed over.

Several missionaries Bai Jin, Lei Xiaosi and others were about to enter the palace.

Because they are not yet on duty, these people have official status, and they were also common when Dai Jinxian was studying Western studies before, and Liu Yu also hurriedly came forward to salute and say hello.

Lei Xiaosi's cultural level is also very high, and he has translated the "Book of Changes" into Latin, and the Chinese name is also taken from the sentence "Yongyan filial piety, filial piety thinking" in the Book of Poetry in "Daya Xiawu".

Whether it was King Louis XIV of France who sent them to spy on intelligence, or whether the Jesuits wanted to go to the upper echelons, objectively these people did make some contributions, and they contributed greatly to the mapping and brought out many students.

Several people were taller than Liu Yu, and after Liu Yu stepped forward and saluted, he asked, "Several adults, what is the matter with entering the palace this time?" ”

Lei Xiaosi's Chinese level is very high, and he has almost no accent, and he saluted and said: "At the behest of Your Majesty, I will go to the inner palace and teach the princes Alzhebala." ”

Although the Chinese level is not low, when he encounters translation problems, Liu Yu can't help but have a big head.

This Algebra is Algebra, algebra, algebra. The etymology originates from the mathematician of the Arab Empire, Al Khorezm. His name serves as the etymology of the Latin word for "algorithm", and his book also serves as the etymology of Western algebra.

Xu Guangqi said that if you want to get through, you must first translate.

Just as Liu Yu had encountered the problem of translating the Rakshasa negotiations before, translation is a very difficult job.

The seeker, Xinyada, is not something that anyone can meet all three of these rules.

If we talk about the translation of Xinyada, it should be the word "coolie". "The Strange Status Quo Witnessed in Twenty Years" said: The word "coolie" was originally a foreign word coolie.

This translation is top-notch. Faith, elegance, and attainment are all occupied.

Xu Guangqi translates Geometry into geometry, which is also a top-notch translation.

However, over the years, there has always been a missing figure like Xu Guangqi, so that Lei Xiaosi still has strange transliteration words like "Alzhebala" popping up in his mouth.

Just as they were about to say a few words to them about the translation, one of the missionaries inside pulled Lei Xiaosi, who was speaking, with an ugly face, and said a few words about the "farmer and the snake" in Aesop's fable.

In this irony, Liu Yu's knowledge was taught by their missionaries, but they didn't expect to teach Liu Yu, and Liu Yu immediately bit them back.

Liu Yu's face was not red, he was not ashamed, he grinned, and Bai Jin came forward to make a round.

Although he was a Jesuit friar, he was first and foremost French, and he was more loyal to France than to the Holy See.

He came to China as a senior intelligence officer sent by Louis XIV, and had the title of academician of the Royal French Academy of Sciences.

Although Liu Yu stabbed these people on the issue of anti-missionary before, the later borrowing of French military uniforms still left Bai Jin with a certain amount of room for maneuver.

has been in China for a long time, and these people are also clear about officialdom, knowing that Liu Yu is going to be reused, Bai Jin is still a little more polite to Liu Yu, and he doesn't want to tear his face.

Bai Jin said: "Liu Shouchang, now that you are a guard, you should compare yourself with the official of the Han Dynasty." Guangjin is virtuous and serves the country, and he can't be a traitor for luck. Although Lingshi Jinxian traveled to Rome, we are still here. Thou shalt come more and discuss learning. ”

Liu Yu thought to himself, can I learn a hammer from you?

But it was not easy to say it directly, so he lowered his head and listened, and replied: "What Lord Bai said is extremely true. I've heard that Newton, an English man, had a copy of Philosophiae Naturalis Principia Mathematica, but I didn't know that you had it in your hands? If so, please lend it to us. ”

Several of the missionaries shook their heads, indicating that they had heard of and had not seen the Principia mathematica of Natural Philosophy, which did not cost them.

As soon as these people left, Liu Yu also went to order, and the emperor directly named him and became the emperor's personal guard.

As personal guards, a few of them are the eldest sons of the prince's family, and the rest are selected by thousands of people, and it is not easy to greet the emperor in front of him, so he exchanged glances with a few acquaintances, which can be regarded as a greeting.

After standing for most of the day, until the afternoon, the emperor was going to the place where the princes were studying. This is not in the inner harem, Liu Yu and others need to follow closely.

Li Gan is not very old, but he already has a lot of children, and he still survived a lot.

When I went, the missionaries were lecturing algebra there, and a group of princes who listened scratched their ears and cheeks.

This generation of mathematics is not difficult, the key is these translations, there is no person like Xu Guangqi to translate the original acute angles, obtuse angles and other words of geometry, many of the words in algebra are transliterated.

Even if Liu Yu had learned a full set in his previous life, he couldn't tear up the book at this time.

After a lecture was finished, the missionaries retreated, and the emperor tested the knowledge of the princes again, and after a few words of encouragement, he complained to Liu Yu.

"Since ancient times, the calendar has not been bad, and it has never been said about the earth. From Westerners to China, there is this saying, and it is in line with the roots. In the previous battle with Rakshasa, it can be known that the place north of Heilongjiang is not very dark after sunset, and the sun rises in half an hour, and the circle of the land and the intersection of yellow and red can be known. There is a lot to learn from Western culture. ”

"However, there are those who are easy to understand and those who are difficult to understand. I studied Western knowledge, geometry and astronomy, which was easy to understand. Only this 'Alzhebara' study is the most obscure. I wonder if these missionaries are not deeply educated? Or is it incomprehensible in itself? ”

"When I became the crown prince, Bai Mingyuan returned from France, and there was a Western celebrity named Leibniz, who dedicated a book to the Academy of Sciences. Tribute to a delicate thing, to the mechanism of control can be counted, I was the prince, look at it, its instrument is quite "easy" ingenuity. It can be seen that many learnings are common to things and things, and such as Confucianism, etiquette, and God's theory of hell, these are different things. ”

"Now that I want to learn something, but I don't even understand this 'Alzhebara', what's the use of establishing an academy? Moreover, if the academy is established, it will invite scholars to be doctors, but if the missionaries are dedicated to preaching, I am afraid that they will take the opportunity to spread. ”

"What do you think?"

Although he complained in front of all the people around him, the rest of the people also knew about the earth, geometry and other things, so they naturally understood that this was said to Liu Yu.

Liu Yu thought to himself that this Leibniz's calculator was still here? After thinking about it for a while, I am afraid that when the emperor was the crown prince, he had seen those exquisite instruments, so he has always maintained a very tolerant attitude towards Western studies.

But what the emperor said was indeed a problem.

In the past, I relied mainly on missionaries. The cultural level of the missionaries is okay, but in terms of scientific literacy, they are certainly not the top ones, and because of the distance, the spread is seriously lagging behind.

Today, among the missionaries in the DPRK and China, they have not even read the "Mathematical Principles of Natural Philosophy" published several decades ago, and they are full of missionaries, and it is certainly not possible to use them.

"Back to Your Majesty. The minister thought that the Rakshasa mission came this time, which was an opportunity. ”

At the moment, he said that his "inference" was actually about to take place.

Li Gan is also a person who grew up in the palace struggle, where do you still not understand? Moreover, the internal fighting in the Rakshasa Kingdom is really a few grades worse than the things contained in the twenty-three histories, and even Li Gan did not give birth to half of the shock of "this son knows the art of palace infighting, and it should not be underestimated".

Even the guard next to him, who heard these things for the first time, thought, that's it?

"Therefore, the minister thinks that the old party of Rakshasa is gaining power, and the new party is lurking. In the future, there may be foreigners who will become the masters, but I am afraid that within twenty years, the Rakshasa capital will be in chaos. There is a great destiny of the Tang Wu Revolution, the Revolution of the Tang Dynasty, and the Life of the Revolution of the Tang Dynasty. ”

"In this way, the government is in chaos, the old party gains power, and the talented doctors hired by the country, such as Euler, Bernoulli, and others, as the ministers have heard, may have to find another place to live."

"Rakshasa is a barbarian in the eyes of Westerners. The fact that they believe in Orthodoxy, rather than God's doubts about Protestantism, still goes shows that most of the people in the Rakshasa Academy are not very convinced of God's Word, and they are also busy with practical learning rather than teachings. That's exactly what we need. ”

Li Gan thought for a moment and nodded: "What you said is very true. Since these people can go to the rakshasa without arguing about religion, what they want is either profit, fame, or a stable environment to concentrate on learning. If this is the case, if the Rakshasa government is in chaos, it is really a method that can be introduced. How does the Euler you speak of compare with the missionaries of the DPRK and China when it comes to geometric arithmetic and other knowledge? ”

"Uh......"

Liu Yu held back for a long time, and could only say: "If you only talk about geometry, arithmetic and other knowledge, just based on what you hear, or think that the glory of rice grains is better than the sky and the moon." ”

Li Gan heard Liu Yu describe others with such beautiful words for the first time, and couldn't help frowning: "If this is the case, I'm afraid this person may not be willing to come." ”

Liu Yu was puzzled, and Li Gan said: "If you want to really learn Confucianism in Korea, Ryukyu, Japan, and Annam, the first place must be the Celestial Empire. The Westerners you are talking about are proficient in learning, and they are only afraid that those who seek will be the supreme way. Western geometry and arithmetic are now higher than our dynasty, how could they come to such a place? Just like my Confucianism, do you want to go to Ryukyu and seek Confucianism? ”

It seems that Li Gan is still very clear in his heart, and what he said is also very reasonable.

It is impossible for the great Confucians of the national dynasty to go to Ryukyu and Korea to study Confucianism; The reverse is also true. This kind of person is only tempted by money, and may not be willing to come, after all, he still wants to study knowledge.

Liu Yu hurriedly said: "You can take advantage of the Rakshasa delegation to come and be shocked." His Majesty is proficient in learning, and there are many students of the Academy of Sciences in the Rakshasa Mission. It will definitely shock the Rakshasa students, and after they go back, they will be able to spread their prestige thousands of miles away. ”

Li Gan's eyes rolled, and he immediately understood what Liu Yu meant.

Obviously, Liu Yu meant that he Liu Yu would ask the question, and then the emperor would come forward to test the knowledge of the Rakshasa students, and the reputation would make the emperor earn, pat himself on the back, and get the business done by the way.

In front of the rest of the people, Li Gan not only understood this meaning, but also thought of the refreshment brought by the breaking of the city that day, and also felt refreshed, and asked: "How sure are you that it will shock his heart?" ”

"Ten percent!"
