One Piece of Song Dynasty

Ma Long nodded and said: "Aside from the fact that the place we live in is a sphere, the Central Plains where we live is actually not the center of the world. In a certain geography book, there is a world map. Our Central Plains is just a very small area on the map. In a small place, the world is still very vast, and there are many places that we have not discovered. "

A Confucian scholar named Zhang Yi said: "Speaking of teaching and educating people, there is an interesting literacy method in this pedagogy of a certain person. Since we are all going to be teachers in the future, we might as well learn it together. I think it is more efficient to use this method to teach children how to read. The book calls this method the pinyin method. These pinyin are all characters from the Far West, but according to the reading method, the spelling of several characters is the pronunciation of our Chinese characters. , and this kind of writing in the far west is extremely convenient, so I think we should use this method to teach children to read. Of course, in addition to some methods of teaching knowledge, this book also talks about the importance of educating people. We teachers should not only teach knowledge, but also teach children the principles of life, cultivate children's good character, and the most important thing is to cultivate children's wolf nature. For some reason, compared with our ancestors, some people feel that the Han people of this dynasty are Having lost the wolf nature of our ancestors, we have become more and more cowardly towards foreigners. We only know one person’s compromise, which makes the foreigners bend their backs. Our ancestors, whether they were strong men or the prosperous Tang Dynasty, had times when they would compromise, but After compromising and giving in, they worked hard and finally defeated the foreigners and expanded their territory. But when it came to this dynasty, what did we do after the Chanyuan alliance with the Liao people? Nothing was done, and we also fought with the Xia Kingdom and Cong Renzong. The war started during the period, and has continued until today's officialdom. The war has stopped for nearly a hundred years. If Xia Guo wants to make peace, he can make peace. In this dynasty, it is others who beat us. We rarely take the initiative to fight others, so we need to focus on it. Shaping the wolf nature of the Han people and re-erecting the bent backbone of us Han people."

A Confucian scholar named Feng Yu interjected: "Hey, if we want to straighten our Han people's spines, we cannot do without this book in the hands of a certain person. This book is called Chemistry. We have all seen firecrackers. The army of this dynasty There are also firearms in it, but we are not very clear about the reasons why gunpowder explodes. However, there are explanations in this chemistry book, and the gunpowder in this book is much stronger than the firecrackers we have seen. In addition to gunpowder, this book There are also many explosives that are far more powerful than the most common black powder. Unfortunately, I can only understand black powder, but I can’t understand the others. I know that there are many things in the world that can be produced if they are mixed with each other. What an incredible thing. I dare to conclude that in future wars, chemistry will definitely shine. Those cold weapons are nothing compared to these explosives. Of course, in addition to being used in war, chemistry can also be used in medicine and ironmaking. Steelmaking, chemical fertilizers, and the medicines we often take are all herbal medicines. However, in addition to herbal medicines, chemistry can also use some things to synthesize some medicines. There are also fuels needed for iron and steelmaking. Chemistry can also synthesize some good fuels. In addition to In addition, there are chemical fertilizers. Chemical fertilizers are mainly used in agriculture, which can increase crop production in large quantities. Of course, I don’t understand most of these, so I think I can work with Ouyang Langjun who is a doctor and who is a steelmaker. Lang Jun, who is studying in Tie Shu, and Xu Langjun, who is studying agriculture, are studying together."

A Confucian scholar named Liang Peng raised his hand and said: "A certain person studies iron and steel making. This book written by a certain person is called Metallurgy, and it talks about iron and steel making. Of course, in addition to steel, there are many metal materials in the world, including copper." It is really a waste to be used to mint money. The book says that the biggest function of copper is to be used as a wire. As for what electricity is, everyone should have seen thunder. Thunder is actually electricity, and wires are used to transmit electricity. As for electricity, The book doesn't go into details about how it came about, it just says it's related to physics. If we can make electricity in the future, then we won't need to use candles for lighting at night. Electric lighting is much better than candles. In addition to making wires, copper It can also be used to synthesize different things with other metals or other substances. This is related to chemistry, so I can discuss it with Zhao Langjun and Feng Langjun."

Zhao Xi nodded and said: "Liang Langjun is right. In addition to being used for lighting, electricity can also be used for many purposes, such as transmitting information. In the past, we could only rely on people riding horses or carrier pigeons to transmit information, but whether it is horseback riding or carrier pigeons, It all takes a long time, but it is different with electricity. It only takes less than a quarter of an hour to transmit information. What a great help this will have to our lives, especially to war. , but to make electricity you only need magnets and wires. The magnets I think everyone knows are made of magnets used on ships, and the wires just mentioned by Liang Langjun are copper wires."

The Confucian scholar named Jiang Shan smiled and said: "However, whether it is physics, chemistry, or metallurgy, the metal materials you need require our prospectors and miners to find and dig out various ores before you can use them. This book of a certain The book is called Prospecting and Mining. Of course, in addition to various ores, we also dig something: kerosene, also called petroleum, used by the army of this Dynasty. In addition to being used for setting fire, petroleum is also a very important raw material. From petroleum Many useful things can be extracted from it, and these things have a lot to do with chemistry."

A Confucian scholar named He An said: "Petroleum is also very useful for my book on aerodynamics. I think the difficulty of my book on aerodynamics is similar to advanced arithmetic. It is also related to physics. It mainly uses Let’s study something that can make people fly, just like birds. Birds are also the main object of our research. This thing will use oil as fuel. I don’t know if the dream of making people fly can be realized in someone’s lifetime. ”

A Confucian scholar named Yan Yunfei said: "Hey, no matter what you want to do, no matter what dream you want to realize, you need the support of money. This finance book by a certain person is all about making money. Whether it is current copper coins or gold and silver, they are not the most suitable." Coins, the best currency in the future is paper money. In fact, paper money has already appeared in this dynasty, that is, Jiaozi, but it is only circulated in southwest Sichuan and other places, and the government does not manage it well. Those in power must ensure the credibility of paper money. The issuance of banknotes can be completely based on gold and silver, but the authority must calculate the annual issuance amount and cannot over-issuance, and banknotes must have anti-counterfeiting technology. Counterfeit banknotes will cause great harm to the credit of banknotes. Of course, finance It also talked about a lot of things, but I haven’t understood it yet. In short, it is to ensure the stable operation of a country’s economy, and to plunder the enemy’s wealth. Financial weapons are more effective than using real swords and guns to plunder the enemy’s wealth. Be good."
