Shouhan now has in his mind a movie he once watched, an actor who was once as famous as Uncle Ge, and played the image of a private teacher in a film that reflects the life of educated youth in Yunnan. He felt that now he was the private teacher, even worse than him!

"Lose that horse! He still has a work allowance or something, but Lao Tzu completely brings his own dry food! I have to edit the textbook myself! ”

Thanks to Van Basten, Alfonso and others, all kinds of Western mathematics books needed by Shouhan to satisfy his "personal hobby" at this time were sent to the current Hue General's Mansion by a steady stream of sea ships.

(What do you mean by their gifts?!) Lao Tzu spent real money! A large number of porcelain and white sugar were all transported with the ship! ）

To say yes, to scold is to scold, Shouhan still has to go through the messy treatises printed in front of him. Comparing different printed editions with each other to prevent errors and fallacies, so that they will be harmed for thousands of years, and by the way, they will nail themselves to the pillar of shame in the academic world.

But there is no way, today's navigation, artillery, construction and many other links and industries, all need to quickly introduce, digest and absorb the essence of Western mathematics such as functions and geometry, and extend them to a wider extent.

Such a difficult and glorious task, who is the pig's foot?

"Damn it!" Shouhan threw a treatise printed in floral characters into the corner, these early mathematical works are very vague and obscure, and if you are not a professional, I am afraid that you will not be able to understand it at all. And to turn these things that are completely different from my original Chinese mathematics system into things that can be recognized by many students, Shouhan is very annoyed, "It would be nice to have a version of high school mathematics taught by myself." It's okay for the third year of junior high school! ”

With a "bang", a book thrown by Shouhan knocked a holy porcelain vase on the table to the ground, and shattered to pieces.

The soldiers on duty outside the door could hear the noise in the study, but they did not dare to move, so they had to honestly follow the requirements of the guards' code and be on duty at their posts. However, Huang Leiting, who was working in the camp office, walked outside the courtyard of Shouhan with several messengers from the official office, heard the movement in the room, and walked in with curiosity.

"Your book, my lord."

Huang Lei carefully picked up the book that Shouhan had discarded aside, and lightly placed it on Shouhan's desk.

Shouhan looked up and saw that it was Huang Leiting, the commander of the artillery division, so he didn't say anything and motioned for him to sit down. He was trying to find someone to talk to and slow his mind, so as not to drive himself crazy.

"Lord, what kind of book is this?" Although Huang Leiting was not very literate, according to the military discipline and officer promotion system formulated by the Shou Han Dynasty, if he could not know 500 words and write simple letters, reports, and documents, he could not be promoted from a soldier to an officer, unless he had made special achievements. An officer of Huang Leiting's level, who has several battalion-level troops under his command, has higher requirements for cultural development. It is precisely because of such a lack of moral requirements that an officer like Lao Huang is forced not to miss any opportunity to learn something.

"It was a book written by an English man. Charlie, the English merchant who had trade with Huang Qiying and others, got it for me. This guy is a mathematician named Henry. Briggs. In the forty-fifth year of Wanli, he put forward a term called the common logarithm. This is his scholarly work published four years earlier (1624), in our words "Logarithmic Arithmetic", there is nothing special in the book, the main thing is that the book has a common logarithmic table of 1-20000 and 90000-100000, and it is accurate to 14 decimal places. At the same time, the calculation method of the common logarithm of 20000-90000 is also given. ”

What is logarithm and what is decimal point, Huang Lei was quite ignorant when he heard it. However, in front of the lord, you can't look like you don't understand it at all, you have to make a look like you listen to it with relish.

"Huh! By the way, Lao Huang, you will send someone to copy a copy of this thing later, it will be useful to you! ”

Seeing Huang Leiting's expression as if facing the emperor's new clothes, Shouhan couldn't help but feel very relaxed, once the mood relaxed, his mind suddenly felt like a wisp of fresh breeze blowing in a room that had been closed for a long time, which made his thinking a lot clearer.

He rummaged through the stacks of books for a while, and found another Briggs book.

"This is a 15-digit sine function table and a 10-digit tangent and secant function table written by Briggs, you go back and take it back, in the battalions of the artillery division, look for those gunners who are well-read and good at calculation, and use this to calculate the distance between the gun position and the target, and then combine the dense position to calculate the elements!"

"If you don't understand, go to the bookstore, where there are the first six volumes of their newly printed "Geometric Original", which have been translated by Xu Xiangguo in Shanghai, and there are also originals, take them to compare and study, and then figure it out, and give me a post in a month to explain the situation!"

Peeking at Huang Leiting's expression as if someone had added a spoonful of poop to his rice bowl, and he had to eat it, the guard at the door snickered in his heart, "Yes!" Who wants you to trespass in without being summoned?! Now find yourself guilty, right?! ”

"This?!"

In Huang Leiting's consciousness, or in the consciousness of all artillery officers in this era, they all believed that the calculation of the firing distance of artillery was calculated through the relationship between the distance and the elevation angle of the gun body, and the application of sine function and cosine function in artillery shooting was still at the point where it was unknown why.

"If you find out what I said, how to combine it with the dense position, and how to cooperate with the elevation angle of the body, the different distances, the different bullet weights, the amount of charge between the types of bullets, and so on, compile them into a book, and popularize them to all artillery units of the whole army, and if this matter is done, you will be the artillery commander of the whole army."

It was a huge problem for Huang Lei to stand out, but at the same time it gave him a huge temptation. Obediently, the artillery commander of the entire South Central Army, that is, the power that was originally limited to the land camp was expanded to the entire South Central Army!

Huang Lei pinched the thin booklets tightly in his hands, as if pinching the seal of his artillery commander, and kept silently reading, "Geometry originally, geometric original." ”

"This, I translate it as power. It can also be called a power. Represents the form of multiplying a number several times, e.g. the power of n a multiplied by a^n, or a^n is said to be the nth power of a. a is called the base of power, and n is called the exponent of power. In the extended sense, the exponent n can also be a fraction, a negative number, or any real or complex number. ”

"Power means 1 number multiplied by itself n times."

"The square root, also known as the quadratic root, for non-negative real numbers, refers to a real number equal to the result of self-multiplication, expressed as [√ ̄], where the square root of non-negative real numbers is called the arithmetic square root. A positive number has two square roots; 0 has only one square root, which is 0 itself; Negative numbers do not have square roots. Example: The square root of 9 is ±3Note: Sometimes we mean the square root of arithmetic. ”

In full absorption (review?) After the mathematical achievements of Westerners in this era, of course, they must use all kinds of plagiarized results to promote them.

Facing dozens of pairs of eyes full of curiosity under the podium, Shouhan was full of pride in his heart. However, a thought flew through my mind, "Who invented these words like power, power, square root?" Don't turn around and let people call me and sue me for plagiarism and plagiarism, and when the time comes, it won't be possible to go to the starting point to file a lawsuit. Trouble for the editors! ”

(Damn the author!) The voice of a little pockmarked came from the distant Zunhua Dongling Tomb, this bullshit thing of yours, take away my Daqing Dynasty and forget it! How can I take away my academic achievements?! ）

("Less nonsense!") If you have the ability to sue me in the Time and Space Administration! In the face of the accusation of the pockmarked who claims to be able to count all the skills of astronomy, the author who has no discipline said. ）

"Basten, we're working on a good deal, aren't we?"

After plagiarizing the academic work of others and unceremoniously promoting it in his own name, Shouhan put the Dutchman, one of the directors of the East India Company, Fan. Basten summoned him to him.

Basten's arrival, in addition to his own business, is to implement the company's procurement plan.

In the past few years, the war in Europe has become more and more intense, whether it is the Danes, the French, the Dutch, the Germans, the Spaniards, almost all the countries on the European continent have been involved, even England in the distance on the three islands has not been spared.

Therefore, the profits of arms are becoming more and more attractive.

Steel, gunpowder, muskets, and all kinds of artillery made in Nanzhong became commodities that could be sold to the warring sides through various channels in the eyes of the gentlemen of the East India Company, which could be used to make huge profits. As for what kind of effect these goods will have on the European continent, I'm sorry, we're just merchants, and killing people and going to war are not our goals. Our aim is simply to make a profit.

As a result, Mr. Van Basten, who had a good cooperative relationship and personal friendship with the South China Army, came to South China again as the trade representative of the East India Company, but this time he received Basten in the royal palace in Hue.

"Of course, cooperation with the Governor will be beneficial to both of us, especially to my family."

Within a few years, the Basten family monopolized trade with the South Chinese army, especially the trade activities of lily porcelain and holy porcelain in mainland Europe, and quickly became the top ten families in the Netherlands in terms of total wealth.

And Mr. Van Basten has contributed a lot to this qiē.

"What are you going to buy this time?"

Shouhan asked kindly, but Mr. Basten couldn't help but feel like the smile of the fox.

"Oh! In view of the war between the countries of Europe, we intend to procure a consignment of military supplies for the defense of the Kingdom of the Netherlands. Here's the list. If your Excellency the Doge deems it possible, allow us to trade with your business, and we will purchase these supplies with gold. ”

Looking at the long list of names and quantities of materials, Shouhan and the civil and military officers beside him were extremely proud and let out bursts of laughter in their hearts, "Who said that building two blast furnaces can meet the needs?!" It seems that the third blast furnace is about to be put on the agenda immediately. ”

"I personally have no problem with the fact that you're going to procure these things. However, business dealings are purely commercial issues, business is business, about the price, you go to talk to the shopkeepers of the Han Yuan firm, in addition, don't forget about my export duties, if you forget to pay taxes, you have to transport the goods, maybe the patrol ships on the sea will accidentally fire cannonballs and sink your cargo ship! ”

"Rest assured, my lord, the East India Company, as a responsible business organization, would never do anything like that. Also, as your friend, I personally have a little gift to give. ”

"Huh?"

Hearing that Basten had a gift for him, Shouhan couldn't help but lift his spirits, and he didn't know what this Dutch red guy would give him.

Mr. Basten waved his hand triumphantly, "Take it!" ”

Several swarthy negroes carried huge cloth bags up the steps of the hall, and their feet had barely stepped on the second section when they were stopped by the loyal guards of the Han guards.

"Okay, don't go any further, just open it."

Mr. Basten, who had also heard about the assassination of Shouhan, motioned for the cloth bag to be put down on the spot, and gestured to one of the guards to borrow the guard's untie knife.

Cutting the rope of the package with a sharp knife and tearing open the sackcloth wrapped outside, the secret hidden in the bag is exposed to the sunlight, "This is the cotton that my family and I have purchased from India for you!" I would like to be able to obtain the exclusive rights to sell those fine cotton textiles of yours on the European continent. ”

The white cotton stretched his body in the air, showing a delicate state, and these cotton made the people around Shouhan feel as if they saw piles of silver in front of them.

"How much cotton has been shipped?"

After the commander stepped forward and took a rough look at the fineness of the cotton, the Shouhan asked Basten in a tone of unscrupulous answer.

"My five ships this time, except for the necessary supplies and gold coins, are all carrying this, Indian cotton!"

It is Indian cotton, not the island cotton that Shouhan expects, since Shouhan has shamelessly plagiarized and improved the Guoxiama textile machine, the cotton spinning industry in the jurisdiction is like a bloodthirsty hungry tiger, eager to try, and is strongly suppressed by Shouhan, no way, there is no stable and reliable cotton source that can meet the demand, and he still remembers the cotton purchase war. This kind of war will be carried out almost every year in Xinjiang, Henan, Anhui and other major cotton provinces, and the warring parties are the major cotton spinning enterprises.

"We must find a way to promote the planting of long-staple cotton, that is, island cotton! With long-staple cotton, it is possible to spin cotton cloth with forty-five yarns at will, and it is also possible for workers with a little better craftsmanship to weave sixty yarns. When the time comes, what endless Hengtang yarn and endless Songjiang cloth will be given to me to go home and cry! ”

"However, we must not put such an important source of raw materials in the hands of the Dutch."

Trying to retract the idea of traveling outside the world, it is very laborious to defend the Han.

"I can sign a long-term contract with you on the matter of cotton, and as for the exclusivity, I think it's better to forget it! After all, I have a lot of needs at the moment. Let's talk about something else for now! My personal hobbies are not limited to earning money and defeating enemies, you know. Go back and help me find these men in your kingdom of the Netherlands, both men and writings, and it is better to get them for me. ”

Well? As long as you have hobbies and requirements, you can do it, but I'm afraid you don't have hobbies and requirements! Mr. Van Basten was in good spirits, and he pricked up his ears to listen carefully to every word that Shouhan said.

"Flac, one of your mathematicians and publishers in the Netherlands, whose works on logarithms I have read and find seem to be fallacious, I am going to have a face-to-face with him. Also, a Frenchman, called Descartes, I recently heard about him coming from France to the Netherlands, and this guy is also very accomplished in the field of mathematics. Don't let it go. If he refuses to come, you tell him that someone here has proposed the concept of exponents, and that there is some mysterious relationship between exponents and logarithms. ”

"I welcome him to Nanzhong to discuss with me. In addition, you can vigorously visit your hometown, and it is also interesting to have a guy named Galileo! ”

Mr. Van Basten, who politely looked forward to the countless gold coins that were about to pour into his treasury, Shouhan looked at the people around him and smiled, "Everyone, how is it?" ”

"The lord is wise, I am ashamed!"

Everyone bowed in unison.

"Come less! Immediately send someone to the dock to inspect the Indian cotton that Basten has shipped, organize people to unload the goods, calculate how long the cotton can last, and when you negotiate with him, think about where you bought this cotton from India. ”

"Lord, how do we set the price of the goods we give him?"

Lin Huofeng, the big shopkeeper of the Han Yuan firm, was a little hesitant, and he was not very sure about the tone of the upcoming business negotiations.

"Hey! Do you want me to teach this kind of thing? How much should it be, add 30%! That's the bare minimum! This guy didn't want to use it himself, but also shipped it back to their hometown, and after the price was raised, he resold it. ”

Hearing Shouhan's words, a group of greedy guys had a bottom in their hearts, turned around and said goodbye, and went back to sharpen their knives, preparing to slaughter Dutch pigs and sheep.

"Tianhua, what are the Portuguese people in Gonzalez busy with lately?"

Chen Tianhua, the manager of the camp office, was left behind by Shouhan.

"Those guys? They are all very happy to work in the practice fleet of the Sailor Academy, in addition to going to sea to train and cruise, piggybacking on the fight against pirates, they are drinking and gambling with a group of Portuguese people, and sometimes, Portuguese women come to the Qinlou Chu Pavilion on the street, and they will also patronize it. Other than that, there is nothing else. ”

"Okay, you inform the Sailor Academy, don't arrange for Gonzalez's guy to go to sea recently, I have something to look for him recently. You sue him. ”

Keep asking for all kinds of support!
