The establishment of the "Young Academy of Sciences" did not attract anyone's attention, and in this era, the status of craftsmen was very low, and the so-called science was regarded by most people as a miracle.

Shen Kuo's "Dream Creek Writings" has a high status in later generations, but in this era, this emperor's masterpiece is not as popular as a song of resentment.

Han Bi'er used the commercial network all over the country to soon recruit more than 100 skilled craftsmen, these people can be regarded as scientists of this era, but their status as craftsmen is not as high as that of ordinary farmers.

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

The Academy of Sciences was built in a corner of the vineyard and was surrounded by a high wall, which was forbidden to idlers.

Yang Yihe and Thirteen Niang, who were dressed as men, entered the Academy of Sciences with a special pot, recruited all the skilled craftsmen in it and said: "Today, I will do a simple experiment for you, everyone will finish the experiment first, and then let's talk about it." ”

Yang Yi personally filled the water into the pot, which had no lid and only a spout, and could only be filled slowly from the spout.

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

"Everyone, stay out of the way, this experiment is a bit dangerous." Under Yang Yi's orders, the craftsmen dodged one after another.

As the water in the kettle was boiled, after a while, a pop was heard, and the wooden cork of the spout flew out instantly, hitting the wall before falling down, and steam continued to spew 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 this vapor meets the iron sheet. This is also crucial, so be sure to see it clearly. ”

After the experiment is completed. Yang Yi continued: "From this simple experiment just now, we can see that water is heated up. It will turn into water vapor, in this transformation process, its volume is constantly expanding, when the space in the pot is not enough to hold so much water vapor, the water vapor will shake the wooden stopper away, if the spout is also sealed, when the water vapor expands to a certain extent, the huge pressure can make the whole kettle explode, which is inevitable. ”

The craftsmen below didn't understand what Yang Yi meant by saying this. Listening puzzledly, even Thirteen Niang looked at him puzzled.

"What I'm trying to say is that there is tremendous power in the process of water heating and turning into water vapor, and what I want you to do now is how to make this power work for me."

As he spoke, he took out the triangle board and the compass and drew them on the blackboard, which he had made for the convenience of drawing and explaining.

"Let's say it's a sealed boiler. When we heat the boiler constantly, we produce a lot of water vapor, which is then channeled here through an iron pipe, which is a cylinder. The cylinder is equipped with a piston that can reciprocate to control the process of steam entering the cylinder, and the piston can be promoted to keep reciprocating;

Behind the piston is a crank connecting rod. The other side of the connecting rod is connected to the crankshaft, so that. The continuous reciprocating motion of the piston can carry the crankshaft continuously through the crank connecting rod. ”

Thirteen Niang said happily: "I understand." As long as you can keep turning the crankshaft you are talking about, it can be like a waterwheel, constantly driving the spinning wheel or other equipment to run. ”

"Yes, that's pretty much how the steam engine works, it's easy to say, but how to make it workable is something that you need to study. In the process of research, we must not forget that the steam from the spout just now will condense into water after encountering a relatively cold iron plate, which must have advantages and disadvantages in the development process. ”

In later generations, most people knew the working principle of the steam engine, which was not difficult to say, but it was another matter to really make it, and what Yang Yi could provide was only an idea, and then let these skilled craftsmen study in this direction.

Yang Yi believes that as long as he continues to invest in manpower and material research, it is only a matter of time before he builds a steam engine, and in 1765, Watt improved the steam engine, and the level of science and technology at that time was not necessarily very high.

It's not that you can't do it, it's that you can't think of it. With Yang Yi's foresight to guide the direction, the future development prospects of the Yang Academy of Sciences will be unlimited.

Yang Yi stood in front of the blackboard, looking at more than 100 skilled craftsmen below, these people are the seeds of the Yang Academy of Sciences, in addition to the generous treatment, these people's family members Yang Yi also settled, helping them solve all their worries, so that these people can devote themselves to scientific research.

"You must remember that the spirit of our Academy of Sciences is to think boldly and carefully verify. Here, no matter what kind of ideas you have, they will not be dismissed as ridiculous, you can freely propose various research projects, submit them, and once approved, you will receive full support in terms of human and material resources. As soon as you produce results, you will receive a high prize, and here you will no longer be lowly craftsmen, I will give you another name: 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: "Another thing you have to do is that in every future study, every step must be recorded in detail, regardless of the success or failure of the experimental results, the process must be recorded in detail and archived." Remember, remember, we are conducting scientific research, not historians writing history books, not the Spring and Autumn penmanship, the data involved in your records must be detailed, the narrative must be clear, some things are difficult to explain in words, but also draw a pattern to illustrate, and strive to make people look at the original according to your drawings and data."

In ancient Chinese books, one of the most prominent problems is that the language is not clear, this is the case in historical books, and the same is true for books in other disciplines.

Yang Yi naturally did not allow such a bad habit 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 working machine, and hurriedly turned back. Explain the concepts they know about machine tools and develop them together.

This is an explanation of machine tools. It took nearly half an hour.

When he got in the car and returned to the city, Thirteen Niang looked at him without blinking his eyes and asked, "Official." Tell me, how did you come up with this? ”

"What's so unexpected, when boiling water, the steam can lift the lid of the teapot, who hasn't seen this? With a little thought, it's not hard to deduce that steam has tremendous power. It's just that no one had thought about how to use this power before;

A few days ago, the lady made a water-powered spinning wheel, which made her husband feel that water power is good, but most places lack rivers, and water power is destined to not meet the demand. Wei Fu thought about something that could replace water power, and happened to see Qing Niang boiling tea, the steam lifted the teapot lid, and Wei Fu has been thinking about how to use the power formed by the steam swelling. ”

Thirteen Niang was full of admiration, little stars appeared in her eyes, Yang Yi couldn't help but smile when she saw it, stretched out her hand to scratch the tip of her nose and smiled: "Lady, you have to remember, you are now the first president of the Academy of Sciences." In the future, you don't have to do everything yourself, just manage the Academy of Sciences, and put forward any ideas you have. Let the technicians study it, if you stay in the courtyard from time to time, your mother will not agree. ”

"Don't worry, official. If the concubine is measured, she will not teach her mother-in-law to be angry. "Thirteen Niang looks like a child who has just eaten candy.

Yang Yi hugged her fragrant shoulder and smiled: "Lady remember to look for more smart and clever children, let them enter the Academy of Sciences as apprentices." Let the skilled craftsmen inside teach while leading, and only in this way can there be successors to the Academy of Sciences in the future. ”

"Well, the concubine has written it down!"

"As long as the lady manages this academy of sciences well, she will not be afraid of not having money in the future, don't look at Bi'er making a lot of money now, but I believe that the academy of sciences will be the largest profit-making institution in our family in the future, and it is also the core of our family."

In all dynasties, whether it is the court or a private person, no one has ever invested so much manpower and material resources in scientific research, Yang Yi is Huo out this time, and now more than 100 skilled craftsmen are just the beginning, and he has to continue to collect talents from all sides, even if he invests one or two million yuan in the Academy of Sciences every year, he will not hesitate to do so.

With such a large investment, coupled with his conscious guidance, it will not be difficult to have a big explosion of science and technology in the Great Song Dynasty in the next few decades.

Now the imperial court is allowed to run private schools, such as Yuelu Academy, Shigu Academy, etc., all belong to private schools, using the mountain chief responsibility system, the college's teaching methods and what kind of teaching materials to choose, etc., are all decided by the college itself.

Yang Yi thought about it, and he also wanted to run a private school, specifically recruiting those students who were interested in science, so that the Yang Academy of Sciences would become an institution integrating teaching and scientific research.

Of course, the meal has to be eaten one bite at a time, and it will take time for the Academy of Sciences to develop, so we will first look for a hundred and ten children to enter, which can be regarded as 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 from afar, and it is now winter, the climate is dry, and it is the most favorable season for digging the river.

Moreover, according to Yang Yi's proposal, the moat should be dug first, and several rivers such as the Bianhe, Caihe, and Wuzhang River could be connected in the future to facilitate the transportation of materials for city construction.

Yang Yi saw a new equipment from the car, that is, the gourd crane newly made by the supervisor, the laborers in the river are using the gourd crane to lift the large stones dug out of the river, only one person needs to pull the iron chain, can lift one or two thousand catties of boulders, these boulders are roughly processed by craftsmen, and can be used as materials for building the foundation of the city in the future.

The closer to Nanxun Gate, the more carriages and horses on the road, and the carriages and horses transporting large bricks, stone strips and other construction materials into the city formed a long queue, so that the Five Cities Soldiers and Horses Division had to send soldiers out to maintain order.

Thirteen Niang saw this busy scene, and said with a smile: "Official, I don't know and think that all this has nothing to do with officials, you, just don't do your business all day long, hehe"

"Who says I don't do my job? Don't you see that Da Song is short of labor everywhere? The husband's current business is to have more children with your wife, we have to work hard to make some contributions to the Great Song Dynasty! Lady spare her life."

On the last day of July, Haoyuan can finally breathe a sigh of relief, these days with illness persevering, very hard, these chapters I feel that I haven't written the effect I want, the chapters are a little messy, I'm sorry everyone, I haven't dared to ask you for a monthly pass. For the sake of Haoyuan's persistence with illness, let's like it a few more times!.
