Win the Ding 1617

() Shouhan's mind is now completely filled with a movie he once watched. An actor who was once as famous as Uncle Ge played the image of a private teacher in a movie reflecting the life of educated youth in Yunnan.Please remember the URL of this site:  …He felt that now he was that private teacher, even worse than him!

"Throw that horse! He still has work points and subsidies, but I completely bring my own dry food! I have to edit the textbooks myself!"

Thanks to Van Basten, Alfonso, and others, all kinds of western mathematics books that Shouhan needed to satisfy his "personal hobbies" were sent to Shunhan today through sea ships. Hua general's mansion.

(What do you mean by worshiping them?! I spent real money! A large amount of porcelain and white sugar were transported away with the ship!)

It's just saying, scolding is scolding, Shou Han has to work hard to read the messy printed treatises in front of him.Compare each other from different printed editions to prevent mistakes, omissions and fallacies, so that it will cause harm for thousands of years, and by the way, nail yourself 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 spread them.

Such a arduous and glorious task, who is better than a pig?

"Damn it!" Shou Han threw a treatise printed in cursive script into the corner. These early mathematical works are very vague and obscure. If you are not a professional, you may not be able to understand them at all.Moreover, it is necessary to turn these things, which are completely different from my original mathematics system in China, into something that many students can agree with. Three is fine too!"

With a sound of "clang", a book thrown by Shou Han knocked a holy porcelain vase on the table to the ground, smashing his body to pieces.

The soldiers on duty outside the door heard the noises in the study room, but they didn't dare to move, so they had to obediently follow the rules of the guards on duty at their posts.On the contrary, Huang Leiting, who was working in the camp affairs office, and several errands from the office passed by outside Shouhan's yard, heard the movement in the room, and walked in out of curiosity.

"My lord, your book."

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

Shou Han looked up and saw that it was Huang Leiting, the commander of the artillery division, and motioned him to sit down without saying anything.He was just trying to find someone to chat with to calm his mind, lest he be driven crazy by himself.

"My lord, what kind of book is this?" Although Huang Leiting didn't know many words, according to the military discipline and officer promotion system established by Shou Han, if he couldn't read five hundred characters and write simple letters, reports, and document records, he couldn't be promoted from a soldier. For military officers, unless there are special merits established.However, an officer of Huang Leiting's level, who has several battalion-level troops under his command, has higher requirements for education.It is because of such immoral demands that officers like Lao Huang are forced not to let go of any opportunity to learn something.

"It was written by an Englishman. It was bought for me by the English businessman Charlie who had business dealings with Huang Qiying and others. This guy is a mathematician named Henry Briggs. He proposed in the 45th year of Wanli A saying is called common logarithm. This is his academic work published four years ago (1624), which is called "Arithmetic of Logarithms" in our words. There is nothing special in the book, mainly because it contains The common logarithm tables of 1-20000 and 90000-100000 are accurate to 14 decimal places. At the same time, the calculation method of the common logarithms of 20000-90000 is also given."

What is a logarithm and what is a decimal point, Huang Lei was very confused.However, in front of the lord, you can't act like you don't understand at all, but you have to act like you are listening with gusto.

"Hey! By the way, Lao Huang, you will send someone to copy this thing back later, it will be useful to you!"

Seeing Huang Lei's expression as if he was facing the emperor's new clothes, Shou Han couldn't help but feel very relaxed. Once he relaxed, his mind suddenly felt like a gust of fresh air blowing in from a room that had been closed for a long time, allowing his thoughts to relax. It became a lot clearer.

He rummaged through the pile of books and found another book by Briggs.

"This is the 15-digit sine function table and the 10-digit tangent and secant function table written by Briggs. You can take it back and look for those who are good at reading and good at calculation in the artillery battalions. The gunner, use this to calculate the distance between the gun position and the target, etc., and then combine the secret positions to calculate the elements!"

"If you don't understand, go to the bookstore. There are the first six volumes of their newly printed "Elements of Geometry", which have been translated by Shanghai Xu Xiangguo, and there are also originals. Use them to compare and study, and then try to figure it out for a month. Give me a post in the future to explain the situation!"

Peeking at Huang Lei's expression as if someone added a spoonful of poop to his rice bowl, and he still had to eat it, the guard at the door chuckled in his heart, "Yes! Who wants you to barge in without being summoned?! Here's to Did you find yourself guilty?!"

"this?!"

In Huang Leiting's consciousness, or in the consciousness of all artillery officers in this era, they all believe that the calculation of artillery firing distance is calculated through the relationship between the distance and the elevation angle of the artillery body. For sine functions, cosine functions, etc. The application of artillery shell hits is still at the point of knowing what it is and not knowing why it is.

"Find out what I said, how to combine it with the secret position, etc., with the elevation angle of the barrel, different distances, different bomb weights, and the amount of charge between the types of bombs, etc., edit it into a book, and send it to the entire army. Promote it to each artillery team, and if this is done, you will be the artillery commander of the entire army."

It was a huge problem for Huang Lei, but at the same time, it was a huge temptation for him.Obediently, the artillery commander of the entire South China Army has expanded the power originally limited to the land battalion to the entire South China Army!

Huang Lei held those thin booklets tightly in his hands, as if he was holding the seal of his artillery commander, and he couldn't help but silently recited, "The original geometry, the original geometry."

"This, I translate it as a power. It can also be called a power. It means a number multiplied several times. For example, the power of multiplying n a's is a^n, or a^n is the nth power of a. .a is called the base number of the power, and n is called the exponent of the power. In the sense of expansion, the exponent n can also be a fraction, a negative number, or any real number or complex number.”

"A power refers to a number multiplied by itself n times."

"Square root, also called quadratic root, for non-negative real numbers, refers to a real number equal to the result of self-multiplication, expressed as [√￣], and the square root belonging to non-negative real numbers is called arithmetic square root. A positive number has Two square roots; 0 has only one square root, which is 0 itself; negative numbers have no square root. Example: The square root of 9 is ±3 Note: Sometimes we refer to the square root of the arithmetic square root.”

After fully absorbing (reviewing?) the mathematical achievements of Westerners in this era, of course, we must promote various plagiarized achievements.

Facing dozens of pairs of eyes full of thirst for knowledge under the podium, Shou Han was full of pride in his heart.However, a thought flew through my mind, "Who invented words like power, power, and square root? Don't turn around and let people call me and sue me for plagiarism and plagiarism. Is it okay to go to court at that time?" . Make trouble for the editors!"

(Damn the author! A little pockmarked voice came from the far away Zunhua Dongling Tomb, this shit of yours, just take away my Qing Dynasty! Why do you want to take away my academic achievements?! )

("Stop talking nonsense! If you have the ability, go to the Space-Time Administration to sue me!" Facing the accusation of Mazi, who claims to be capable of astronomy and calculation, the author without restraint said so.)

"Basten, is our cooperation going well?"

After finishing plagiarizing other people's academic achievements and unceremoniously promoting them in his own name, Shou Han appointed Fan, a Dutchman and one of the directors of the East India Company.Basten summoned to himself.

Basten's arrival is not only for his own business, but also to implement the company's procurement plan.

In the past few years, the flames of war in Europe have become more and more intense. Whether it is the Danes, French, Dutch, Germans, or Spaniards, almost all countries on the European continent have been involved. Even England in the three islands in the distance Failed to be alone.

Therefore, the profit of arms is becoming more and more attractive.

Steel, gunpowder, muskets, and all kinds of artillery manufactured by Nanzhong have become commodities that can make huge profits in the eyes of the gentlemen of the East India Company, and can be sold to the warring camps through various channels.As for what kind of effect these products will create on the European continent, I'm sorry, we are just businessmen, and killing people and war are not our goals.Our purpose is just to make a profit.

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

"Of course, the cooperation with the governor is very beneficial to both of us, especially to my family."

For a few years, the Basten family monopolized the trade with the South Central Army, especially the trade of lily porcelain and holy porcelain to the European continent, and quickly became the top ten families in the Netherlands in terms of total wealth.

And all this, Mr. Van Basten contributed a lot.

"What are you going to buy this time?"

Shou Han asked very kindly, but Mr. Basten still thought it looked like Reynard's smile.

"Oh! In view of the war among European countries, we intend to purchase a batch of military supplies for the defense of the Kingdom of the Netherlands. This is the list. If the governor thinks it is okay, please allow us to start trading with your business organization , we will use gold coins to buy these supplies.”

Looking at the names and quantities of a long list of materials on the list, Shou Han and the civil and military personnel beside him all burst into laughter in their hearts, "Who said that building two blast furnaces can meet the needs? It seems that the third blast furnace will be put on the agenda immediately."

"As for your purchase of these things, I personally have no objection. However, commercial transactions are purely commercial issues, and business is business. Regarding the price issue, you should go and talk to the shopkeepers of the Hanyuan Company. In addition, don't forget My export tariff, if you forget to pay the tax and you have to transport the goods away, maybe the patrol ship on the sea will accidentally fire shells and sink your cargo ship!"

"Please rest assured, my lord, as a responsible business organization, the East India Company will never do that kind of thing. Besides, as your friend, I personally have a little gift to give."

"Ok?"

Hearing that Basten had a gift for him, Shou Han couldn't help but lift up his spirits, wondering what this Dutch guy would give him.

Mr. Basten waved his hand back proudly, "Bring it up!"

Several dark black men carried huge cloth bags one by one and walked up the steps of the hall. As soon as their feet stepped on the second section, they were stopped by the loyal guards of the guards.

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

Mr. Basten also probably heard about the assassination of the guard, and motioned to put down the cloth bag on the spot. He repeatedly gestured to a guard, motioning to borrow the guard's hand-relief knife.

Cut the rope of the package with a sharp knife, split the linen wrapped outside, and the secret hidden in the bag is exposed to the sun, "This is the cotton that my family and I purchased from India for you! I hope to get The exclusive right to sell your exquisite cotton textiles on the Continent."

The pure white cotton stretched its body freely in the air, showing a delicate state. These cottons made people around Shou Han feel as if they saw piles of silver in front of them.

"How much cotton has been shipped?"

After ordering people to go forward and have a rough look at the quality of these cottons, Shou Han asked Basten in an indifferent tone.

"My five ships this time, except for the necessary supplies and gold coins, all transported this, cotton from India!"

It is Indian cotton, not the sea-island cotton that Shouhan was expecting. Since Shouhan once again shamelessly plagiarized and improved the spinning machine, the cotton spinning industry in the area under his jurisdiction is like a bloodthirsty hungry tiger. Han used force to suppress it. There was no other way. There was no stable and reliable source of cotton whose output could meet the demand. He still had a fresh memory of the cotton purchase war.This kind of war is carried out almost every year in major cotton provinces such as Xinjiang, Henan, and Anhui, and the parties to the war are major cotton spinning companies.

"We must find a way to promote the cultivation of long-staple cotton, that is, sea-island cotton! With long-staple cotton, cotton cloth with 45 yarns can be spun casually, and a worker with a little better craftsmanship can weave [-] yarns. Yarn is also possible. At that time, I will go home and cry for all the endless Hengtang yarn and endless Songjiang cloth!"

"However, such an important gateway as the source of raw materials must not be placed in the hands of the Dutch."

Trying to withdraw the thoughts of traveling beyond the sky, Shou Han is very strenuous.

"I can sign a long-term effective contract with you on the cotton matter. As for the exclusive right, I think it's better to forget it! After all, I have a lot of needs at the moment. Let's talk about other things first! My personal hobby is not limited to making money. Take money and defeat the enemy, you know this too. Go back and help me find these people in your Kingdom of the Netherlands. You need both people and books, and it’s best to get them for me.”

Um?As long as you have hobbies and requirements, it’s easy to handle, I’m afraid you don’t have hobbies and requirements!Mr. Van Basten was refreshed, and he listened carefully to every word Shou Han said.

"You have a mathematician and publisher Flack in the Netherlands. I have read his work on logarithms. I think it seems a bit fallacious. I plan to discuss it with him. Also, a Frenchman named Descartes Yes, recently I heard that he came to the Netherlands from France. This guy is also very accomplished in mathematics. You must not let it go. If he refuses to come, you tell him that someone here has proposed The concept of exponents, and there is some mysterious relationship between exponents and logarithms."

"I welcome him to come to Nanzhong to discuss with me. In addition, you can vigorously investigate in your hometown. There is a guy named Galileo, which is also very interesting!"

Shou Han politely looked forward to Mr. Van Basten, who was looking forward to countless gold coins pouring into his warehouse, and smiled at the people around him, "Everyone, how are you?"

"My lord is wise, I am ashamed!"

Everyone bowed and saluted in unison.

"Come on! Send someone to the pier right away to check the Indian cotton that Basten brought in, organize people to unload the cargo, figure out how long the cotton can last, and, when you negotiate with him, try to touch it , Where did the cotton come from India?"

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

Lin Huofeng, the shopkeeper of the Hanyuan Company, was a little hesitant. He was not 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 [-]% to all! This is the minimum standard! This guy doesn't want to use it himself, but also transports it back to their hometown. After increasing the price, he sells it."

Hearing Shou Han's words, a group of greedy fellows got their minds right, turned around and said goodbye, went back to sharpen their knives, and prepared to slaughter the guinea pigs and sheep.

"Tianhua, what are the Portuguese in Gonzalez doing recently?"

Chen Tianhua, the general manager of the camp affairs office, was kept by Shou Han.

"Those guys? They are all very happy working in the practice fleet of the Naval Academy. Apart from going out to sea for training and cruising, and incidentally fighting pirates, they drink and gamble with a group of Portuguese. Sometimes, Qin on the street There are Portuguese women in the Lou Chu Pavilion, and they will also visit. Other than that, there is nothing else to do."

"Okay, please inform the Naval Academy. Don't arrange for Gonzales to go to sea recently. I have something to ask him recently. Tell him."

Keep asking for support!
