"In fact, the multiplication table has been widely spread as early as the Spring and Autumn Period, and division is the inverse operation of multiplication, just like we go out for work every morning and go home to rest every night. The nobles in the book "Zhou Li" The six arts refer to etiquette, music, archery, control, calligraphy, and mathematics. The 'number' involved is mathematics! In the Zhou Dynasty, people who did not understand mathematics, even nobles, were considered to be uneducated. , because there is no one in the aristocracy who cannot understand numbers and arithmetic, unless he is born a fool. The book "Nine Chapters of Arithmetic" developed from the "Nine Numbers" of the Zhou Dynasty has covered many more complex calculations, such as four points. One plus one-sixth is equal to 'A' plus one-twelfth. What is the numerical geometry of 'A'? This is the simplest 'combining and division' operation. When it comes to graphics, "Nine Chapters of Arithmetic" also There are more than twenty volume calculation formulas given, such as the slope-like 'Qianda'. The volume formula is 'vast multiplied by the height, two into one'. The calculation formula is written in Western letters. The expression is V=1/2abh. In the future, I hope everyone can take the initiative to learn the Western alphabet. This alphabet, combined with Tianzhu numbers, will be very convenient in calculations."
Bo Jue, who is extremely smart, has mastered numbers and letters and can flexibly apply them to actual calculations. Naturally, he is full of praise for this simple model.
In the past, I used a brush. If I wanted to save pen and ink, I could only use stones to draw on the wall. Now that I have a pencil, it also comes with Western letters and Tianzhu numbers, which can be said to be twice the result with half the effort.
What the prince said is extremely simple for a top talent like Bo Jue. As long as he has understood the consistency of these numbers and seconded some previous theoretical knowledge, it is easy to understand what is introduced in "Nine Chapters of Arithmetic" matrix.
"Don't think that the Western Yi are barbarians. I learned from the Immortal Realm that the Western Yi have equaled our Ming Dynasty in science, and even surpassed our Ming Dynasty in certain fields, such as military industry. If our Ming Dynasty does not continue to strive for self-improvement, then there will eventually be One day we will be defeated by the Western Barbarians. We must study with great concentration and carry forward the academic knowledge handed down from our ancestors. We should study with an open mind and absorb the essence of the advanced technologies of the Western Barbarians."
A certain prince wants to adopt the strategy of "teaching the barbarians their skills to control the barbarians", but he cannot say this directly, otherwise if it reaches the ears of the warlock Lao Tang, it will have a different taste...
These warlocks still have a certain value, so we can't just get rid of them all. At least we have to wait until they come back to see if they can bring some European mercenaries.
A certain prince actually wanted to join the "anti-Erban camp" so that he could legitimately send troops to Luzon and take back Luzon Island, which was occupied by Spain.
However, most of the cannon fodder that can be hired currently are within the territory of the Holy Roman Empire. If you want to get these people, you must rely on the power of Rome and have good relations with the "Erha camp".
There is no problem in relying on Rome. Anyway, the national flag of the Ming Dynasty will be the "Shen Zi Banner" in the future. This will definitely win the favor of Rome. However, there is a conflict of interest between the Ming Dynasty and Spain. This position is in Luzon.
A certain prince really hopes to get the grain-producing land of Luzon. Having this place is equivalent to directly developing two or three treasure islands, or owning an overseas "Huguang Granary".
Nowadays, both the imperial court and the Eastern Palace are short of money. What they are short of is food. Without enough food, it is impossible to launch a counterattack against the Eastern Lu. This is the most basic thing.
If 300,000 combat troops were mobilized to relieve Zu Dashou who was stationed in Jinzhou, based on two kilograms of food per person per day, it would reach 100,000 shi per month.
The cost of fighting for half a year is 600,000 dan. Taking into account the consumption of war horses and accompanying soldiers, at least 1 million dan must be saved to attack outside the pass.
If you want to have a long-term confrontation with Huang Taiji, you will need to accumulate two million stone grain and grass. To reach this amount, you will need to save for at least one to two years.
In other words, the Ming army would not be able to obtain the supplies needed to launch an attack until the fourteenth year of the transfer of responsibility, 1641 AD at the earliest, which is the year after tomorrow.
In modern times, ammunition reserves determine the time limit of war, but in ancient times, it depended on food reserves. The army must withdraw before the army rations are used up, otherwise the enemy will make dumplings.
A certain prince wanted to get a granary in Southeast Asia, but Annan was difficult to occupy. The monkeys there were stubborn. If only a small number of ground troops were sent, it would be difficult to achieve long-term occupation.
Luzon belongs to the Spanish Empire, and it is easy to capture it. This is tantamount to offending the other party, and may also suffer retaliation from the other party.
Regarding these two camps with obvious advantages and disadvantages, a certain prince was very confused about how to choose. At the moment, he could only take one step at a time and wait until the time comes.
"I can responsibly tell you that only ignorant people in the world think that they know everything. The more knowledgeable a person is, the more likely they are to discover their own shortcomings and shortcomings, so as to learn from each other's strengths and constantly improve their own cultivation and knowledge reserves. I don’t want to see ignorant people in the Academy of Sciences, because this is the palace of knowledge. Here, whoever has more knowledge can make more money. It is no exaggeration to say that knowledge is a golden mountain Silver Mountain has its own gold house in the book. Whoever can take out the gold in the gold house depends on who has the ability. This is why I appointed Song Yingxing as the president of the Academy of Sciences."
Lao Songtou is simply a bug in this era. "Tiangong Kaiwu" alone involves agriculture, industry, commerce, and military aspects. To say it is an encyclopedia is an underestimation.
To buy a book like this, as long as you are literate and have some financial resources, and go back and study it carefully, you can make your family business prosperous.
Due to space limitations in "Tiangong Kaiwu", some contents only give a general introduction, and Song Yingxing has a mountain of information in his hands.
If these materials were really re-edited and a PLUS version of "Tiangong Kaiwu" was published, it would probably be ten times as thick as the original book.
Since ancient times, it has been easy to read but difficult to write. Even if you read a hundred books, you may not be able to write a book. The fact that Lao Songtou can write an encyclopedia shows how powerful his own knowledge reserve is.
With such a powerful person standing in the way, no one in the Academy of Sciences would dare to stir up trouble. The consequences of challenging this man who knows everything and is clever will be very miserable. Not even Bo Jue, the number one scoundrel under his command. The irritating Lord...
Ordinary craftsmen can only look up to Bo Jue in terms of their ability. To see Dean Song, who is proficient in all major industries, he would probably have to lie down on the ground. There is no other option except hugging his thigh.
"I have said before that science includes physics. Physics is the subject that studies the structure and principles of objects, and machinery is one of the goals of physics research. "Tiangong Kaiwu" written by Dean Song has research in this area It is very remarkable. His Majesty Emperor Taizu Gao admired it very much after seeing it, and I admire it very much."
Saying this can establish Lao Songtou's prestige in the courtyard. Although there is no evidence to prove that Zhu Laoliu has read this book, no evidence is needed for borrowing Zhu Laoliu's stinky tofu name. A certain prince's argument is irrefutable evidence.
"Machinery is our most common object. The carriage is a machine, the millstone is a machine, and even the scales used for buying and selling fruits also belong to the category of machinery, and these are all external manifestations of 'force'. The Mohists pointed out that 'force is the punishment' Therefore, Fen means force. It is called "heavy", "down, lift, heavy Fen". This means that physical weight is the expression of force, both falling and lifting. The 'windlass' we use to draw water at the mouth of a well, It is the most accessible machine that uses mechanics, but do you know the scientific principle? This principle is the 'lever principle', that is, the pulling force we use multiplied by the distance from the rocker arm to the axis of the pulley is equal to the weight of the bucket multiplied by The radius of the pulley, it can be seen that the distance of the rocker arm is much larger than the radius of the pulley, so the force we use can be less than the weight of the bucket. The specific formula is FL=GH! Once the practical experience is abstracted, The essence can be obtained, which is the formula, and the formula can be applied to any applicable scope, such as winches, pulleys and other similar machinery."
The introduction of a certain prince opened the eyes of the group of "knowledge eaters" below. It turned out that just fetching water could be represented by symbols, which they had never expected before.
Looking at the force analysis diagram of the windlass drawn by the prince with chalk on the blackboard, Song Yingxing was obsessed with it and could not extricate himself. This was knowledge that he had not been exposed to for decades of studying machinery.
"Many people must know that the Academy of Sciences is currently studying steam machinery. The principle of this machinery is to use the pressure generated by steam to promote the movement of the entire machine. Then some people would think how powerful the steam is, which can push hundreds of kilograms or even more. What about the thousand-pound machinery? I will give you an example. Every household will boil water with a kettle. When the water boils, the kettle lid will be pushed open by the steam. Then I will use a kettle as big as a water tank to boil water. From this How much steam is generated? How much force is generated when the steam rises? Only when you understand the steam engine will you be able to get started in the field of machinery. In the future, I will introduce the ironclad battleship, that is, the whole body is made of steel. Battleship, why won’t this battleship sink into the water? If you don’t understand the reason, you will be laughed at.”
The Academy of Sciences has produced the most primitive steam engine, which is a large stove and a large kettle, and then connected to a twisting arm and a bunch of gears.
However, the biggest feature of the 1.0 version of the Daming steam engine is not its high horsepower or beautiful appearance, but its tendency to "explode", almost every time!
The longest stable operation time is only three hours. The rest of the time, this machine is "losing its temper". If you are in a good mood, it will be cloudy for a while, and if you are in a bad mood, it will simply shut down and stop playing with you.
If it were not for the proper protection of the leather coat, Bo Jue would have been lying in the army hospital receiving treatment for burns. It can be seen that working on a "water boiling machine" is also very dangerous.
"With the steam engine, farmers can plow the land even if they don't have cattle at home, because if they put a pulley on the steam engine, feed some coal, the machine can start by itself, and then hitch a plow behind it to plow the land. If you put armor on the steam engine, it becomes With hundreds of invulnerable chariots, my master, King Ming, no longer has to fear the Donglu cavalry from now on. Therefore, working as an errand at the Academy of Sciences can, at best, support a family and make a living easily. In the past To put it bluntly, it can benefit the people, and it can also protect our country!"
The progress of steam engine research and development is lower than a certain prince's expectations. According to the current progress, it is estimated that a relatively stable small steam engine will not be built until next year.
It is estimated that it will take four or five years for the Ming Dynasty King's Division to equip steam tanks. If it had been earlier, either a "pure natural engine" would have been used, or on the battlefield, more than half of the tanks would have broken down due to engine explosion before reaching the battlefield.
In general, it is easier to build a tank than a train, and the train must lay tracks, otherwise it will not be able to move. In order to prevent the railroad tracks from being stolen, "railroad soldiers" must be formed to protect them.
"I can be responsible for saying that the future of the Ming Dynasty does not lie with the merchants, soldiers, and farmers, but with you. Because your knowledge is the driving force for the development of the name, and your talents and learning are the treasures possessed by the Ming Dynasty. Those who study science The depth and breadth determine the future destiny of the Ming Dynasty. The most precious wealth in the world is not gold, silver and jewelry, but scientific researchers. I thought that with the talent and learning of Dean Song, Xiyi gave me one million taels of silver. They don’t even care!”
The purpose of deceiving the audience is to motivate these guys to work. Only by increasing their value can the audience generate a higher enthusiasm for work.
And Song Yingxing is not for sale in the Ming Empire. The value of just one person is equivalent to a hundred thousand troops, and it does not consume as much food as a hundred thousand foodies. This is the most important thing...
"If you want to keep your family fed and clothed, you must study hard and strive for the top. I will arrange time to assess your work and knowledge. If you get the corresponding professional title, you can enjoy the corresponding treatment. The Academy of Sciences does not There will be salary arrears. You will receive your full monthly salary on time every month, and the salary is the highest among all the yamen in Ming Dynasty. Why is it the highest? I have already explained the reason in the previous chapter. "
The annual salary of craftsmen working in the Academy of Sciences is one hundred taels of silver, which is a fixed amount, that is, the basic salary. If there is an invention and creation, and it is found to be valuable after being reviewed, a high bonus will be given.
If a craftsman earns eight taels a month, the family will basically have no worries about food and clothing. As long as they don't spend money lavishly, the whole family will live a good life, even in the capital where prices are relatively high.
Previously, a certain prince found that the price of food in the capital was a bit unbearable, so he took advantage of the situation and invented food stamps. With the tickets, everyone in the Academy of Sciences could buy low-priced food for two taels of silver and one stone.
Each person is limited to one stone, which should be enough to feed a family of ten for a month. This is considered one of the things to wait for. If you want to buy more, you have to spend more money. In the grain stores outside, one stone of rice can be sold for four or five taels of silver.
"However, I have spoken first, and the Academy of Sciences also has confidentiality regulations. Even if it is to family, friends, and fellow villagers, you cannot leak any information to them, otherwise you will be severely punished. This place is very close to Dongchang, and I don't want to see anyone. After exiting this door, you entered the courtyard of the East Factory. There are also many machines in the prison over there, but they must be objects that you don't want to touch in your life. The machines there are used to 'serve' suspects. As for how to serve, You are all industry insiders, so you naturally know it well!”
As long as it is leaked, even if Huang Taiji cannot get the prototype, his craftsmen can imitate the drawings and develop something similar.
When Braid also has primary tanks, the days of great confrontation with the dynasty will be even more difficult, but the audience will be blessed to see the tank battles between the Ming and Qing Dynasties...
