The Illegitimate Son of the Song Dynasty Volume 4 Chapter 741 Build an Academy of Sciences at Home

Previous page        Return to Catalog        Next page

    The establishment of the "Yang Academy of Sciences" did not attract anyone's attention. In this era, the status of craftsmen was very low, and so-called science was regarded by most people as strange skills and tricks.

    Shen Kuo's "Mengxi Bi Tan" has a high status in later generations, but in this era, this huge work is not as popular as a poem about a woman's grievances.

    Han Bier used the business network across the country to quickly recruit more than a hundred skilled craftsmen. These people can be regarded as scientists of this era, but the status of their craftsmen is not as high as that of ordinary farmers.

    When Yang Yi came to visit these skilled craftsmen, he gave them extremely high courtesy, which made these people feel apprehensive and grateful.

    The Academy of Sciences was built in a corner of the vineyard, surrounded by high walls, and no one was allowed to enter.

    Yang Yi and Thirteenth Niang, who was dressed in men's clothing, entered the Academy of Sciences with a special pot. They gathered all the skilled craftsmen inside and said, "Today, I will do a simple experiment for everyone. Let's finish the experiment first, and then we'll talk about it."  .¡±

    Yang Yi personally filled the pot with water. The pot had no lid and only had a spout. When filling the water, you could only fill it slowly from the spout.

    After filling the water, plug the spout of the kettle with a wooden plug, and then put the kettle on the stove.

    "Everyone, please stay away. This experiment is a bit dangerous." Under Yang Yi's instructions, the craftsmen avoided one after another.

    As the water in the kettle was boiling, after a while, a popping sound was heard, and the cork of the spout flew out instantly, hitting the wall before falling down, and steam continued to spurt out from the spout.

    Yang Yi walked over with the craftsman, holding a piece of iron sheet in his hand to block the steam emitted from the spout.

    "Everyone, pay attention to what happens when the steam meets the iron sheet. This point is also very important. You must see it clearly."

    After the experiment is completed.  Yang Yi continued: "From the simple experiment just now, we can see that after water is heated, it will turn into water vapor. During this transformation process, its volume will continue to expand. When the space in the pot is not enough to accommodate such  When there is too much water vapor, the water vapor will blow away the cork. If the spout is also sealed, when the water vapor expands to a certain extent, the huge pressure will cause the entire kettle to explode, which is inevitable."

    The craftsmen below did not understand what Yang Yi meant by these words.  Everyone listened in confusion, and even Thirteenth Mother looked at him in confusion.

    "What I want to say is that the expansion process of water heating and turning into water vapor contains huge power. What I want you to do now is how to make this power work for me."

    As he spoke, he took out a set square and a compass and started drawing on the blackboard. These three things were made by him to facilitate the drawing and explanation.

    "Suppose this is a sealed boiler. When we continuously heat the boiler, a large amount of water vapor will be generated, and then the steam will be led here through the iron pipe. This is a cylinder. A reciprocating piston is installed in the cylinder to control the steam.  The process of entering the cylinder can theoretically push the piston to reciprocate continuously;

    ?And a crank connecting rod is connected behind the piston.  The other side of the connecting rod is connected to the crankshaft, like this.  The continuous reciprocating motion of the piston drives the crankshaft to rotate continuously through the crank connecting rod.  "

    Thirteenth Niang said happily: "I understand. As long as the crankshaft you mentioned can be kept rotating, it can be like a waterwheel, constantly driving a spinning wheel or other equipment to run."

    "Yes, the principle of this steam engine is roughly like this. It is easy to say, but how to make it practical requires everyone to study. During the research process, everyone must not forget one thing, the spout of the pot just sprayed  The steam that comes out will condense into water when it encounters a relatively cold iron plate. This must have pros and cons during the development process. It's up to you if you turn the cons into advantages."

    In later generations, most people know the working principle of a steam engine. It is not difficult to say it, but actually making it is another matter. What Yang Yi can provide is just an idea, and then let these skilled craftsmen research in this direction.

    Yang Yi believes that as long as manpower and material resources are continuously invested in research, it will only be a matter of time before a steam engine is built. In 1765, Watt improved the steam engine. The technological level at that time was not necessarily very high. It could be done, and the craftsmen of the Song Dynasty had a theoretical foundation.  , it should be possible.

    Many things are not impossible, but unexpected.  With Yang Yi's foresight and foresight guiding the direction, the future development prospects of Yang's Academy of Sciences will be limitless.

    Yang Yi stood in front of the blackboard and looked at the more than a hundred skilled craftsmen below. These people are the seeds of the Yang Academy of Sciences. In addition to generous treatment, Yang Yi, the family members of these people, has also been resettled to help them solve all their worries.  , so that these people can devote themselves wholeheartedly to scientific research.

    "You have to remember the past, IThe spirit of the Academy of Sciences is to make bold assumptions and be careful to verify.  Here, no matter what your ideas are, they will not be dismissed as ridiculous. You can freely propose various research projects and submit them. Once they pass the review, you will receive full support in terms of manpower and material resources.  Once results are achieved, you will receive high bonuses. Here, you are no longer humble craftsmen. I will give you another title: technician, or scientist.  "

    There was no applause, no cheers, more than a hundred people were silent, but everyone's eyes slowly turned red.

    Yang Yi said: "One more thing, you must do it. In every future research, every step must be recorded in detail. Regardless of the success or failure of the experimental results, the process must be recorded and archived in detail. Remember, remember  , what we are conducting is scientific research, not historians writing history books, and they have no reference to the Spring and Autumn Period brushwork. When you make records, the data involved must be detailed, and the description must be clear. There are some things that are difficult to explain in words, and you must draw pictures to explain, and strive to make it easier for people to understand.  People can copy the original thing based on your drawings and data at a glance."

    One of the most prominent problems in ancient Chinese books is that they are unclear. This is true for history books, and it is also true for books in other disciplines. Because there are no detailed records of many exquisite craftsmanship, future generations cannot copy them at all. It is often only heard of their names, but it is difficult to understand their meaning.  .

    Yang Yi naturally does not allow such bad habits to exist in his own Academy of Sciences.

    When he was about to leave with Thirteen Niang, he suddenly remembered the machine tool known as the work machine, and quickly turned back.  Explain all the concepts you know about machine tools and let them develop them together.

    This is an introduction to machine tools.  It took nearly half an hour.

    When she got on the car and headed back to the city, Thirteen Niang looked at him without blinking and asked, "Guardian, tell me, how did you come up with this?"

    "What's unexpected about this? When boiling water, the steam can lift the lid of the teapot. Who has never seen this? As long as you think about it for a moment, it is not difficult to deduce that steam contains huge power. But no one has thought about it before.  Just use this power;

    A few days ago, my wife made a water-powered spinning wheel, which impressed my husband. Water power is good, but most places lack rivers, so water power is destined to be unable to meet demand.  Wei Husband was thinking about something that could replace the power of water. He happened to see Qing Niang making tea and the steam lifted the lid of the teapot. Wei Husband has been thinking about how to use the power formed by the swelling of steam.  "

    Thirteenth Niang was full of admiration, with stars in her eyes. Yang Yi couldn't help but smile when he saw it. He reached out and scratched the tip of her nose and said with a smile: "Madam, remember, you are now the first dean of the Academy of Sciences. From now on.  You no longer have to do everything yourself, just run the Academy of Sciences well. If you have any ideas, put them forward. Let the technicians study it. If you stay in the courtyard all the time, my mother will definitely not agree. "

    "Don't worry, sir. If I am a sensible person, I will definitely not make my mother-in-law angry. Hee hee." Thirteenth Niang looked like a child who had just stolen candy.

    Yang Yi hugged her shoulders and smiled and said: "My lady, remember to look for more smart children and let them enter the Academy of Sciences as apprentices. Let the skilled craftsmen there teach them as they go. Only in this way can the Academy of Sciences be able to have successors in the future."

    "Well, I have written it down!"

    "As long as I manage this Academy of Sciences well, I won't be afraid of losing Zhuchai's reputation in the future. Although Bi'er earns a lot now, my husband believes that the Academy of Sciences will be our family's largest profit-making institution and the core of our family in the future.  .¡±

    Throughout the dynasties, no one, whether it was the court or private individuals, had ever invested so much manpower and material resources in scientific research. Yang Yi went out this time. Now, more than a hundred skilled craftsmen are just the beginning. He has to continue to collect talents from all sides.  Even if he invests one or two million yuan into the Academy of Sciences every year, he will not hesitate.

    With such a large investment and his conscious guidance, it will not be difficult to have a technological explosion in the Song Dynasty in the next few decades.

    Now the imperial court allows private schools, such as Yuelu Academy and Shigu Academy, which are private schools and adopt the mountain head responsibility system. The college's teaching methods and what kind of teaching materials are selected are all decided by the college itself.

    Yang Yi has thought about it, and wants to set up a private school to recruit students who are interested in science, so that the Yang Academy of Science can become an institution that integrates teaching and scientific research.

    Of course, we have to eat one bite at a time, and it will take time for the Academy of Sciences to develop. We will first identify a hundred children to join, who will be considered the first batch of students.

    When passing through the outer city, tens of thousands of laborers are digging the moat, and the noise can be heard in the distance. It is winter now, and the climate is dry, which is the most conducive season for digging rivers. When spring comes, there will be more rain.  But it¡¯s difficult to work.

    And according to Yang Yi¡¯s suggestion, dig firstThe moat will be able to connect the Bian River, Cai River, Wuzhang River and other rivers in the future to facilitate the transportation of city construction materials.

    Yang Yi saw a piece of new equipment from the car, which was the hoist crane newly manufactured by the supervisor. The laborers in the river were using the hoist crane to lift the large rocks dug out of the river. Only one person needed to pull the chain.  One or two thousand kilograms of large stones can be hoisted. These large stones can then be roughly processed by craftsmen and used as materials for building city foundations in the future.

    The closer we get to Nanxun Gate, the more carriages and horses there are on the road. The carriages and horses transporting large bricks, stone bars and other building materials into the city form a long queue, so much so that the Five Cities Military and Horse Division has to send soldiers out to maintain order.

    Seeing this busy scene, Thirteenth Mother smiled and said: "Official, if you don't know, you would think that all this has nothing to do with the official. You, you just don't do your job all day long, hehe."

    "Who says I don't do my job properly? Haven't you seen the shortage of labor everywhere in the Song Dynasty? My husband's job right now is to have more children with you, my wife. We have to work hard to contribute to the Song Dynasty! Madam, please forgive me."

    On the last day of July, Haoyuan can finally breathe a sigh of relief. It has been very hard to persevere despite being ill these past few days. I feel that these chapters have not produced the effect I wanted. The chapters are a bit messy. I'm sorry to everyone. There has been no  I dare to ask everyone for monthly votes.  For the sake of Hyway persevering despite being sick, please give me more likes!  .
