Chen Xin, Zhang Motan, and Fan Yunzhong, who were teachers, did not teach the same way as the students who had previously graduated from the school when they taught physics and nature courses. In the past, they only talked about it in class to let you know about it, but Chen Xin and they not only taught in the classroom, but also took everyone to do experiments and physical teaching.

Regardless of their age, they have already participated in a lot of research projects in their respective fields, and it is only because they do not have the strength to set up their own research laboratories that they do not have the opportunity to independently experiment with the topics they want to study. Now that they are back here, they have human, material, and financial resources, and they can do what they want to do. One by one, they are preparing research projects that they are interested in, and they have a feeling of madness. Erya not only strongly supports it, but also puts forward what they need from time to time, so that they can research and manufacture it as soon as possible.

At present, what Erya is most anxious about, and they don't have to bother to research, is the resin sunglasses that they have learned how to make. They also took the students to the production workshop to observe the physics class, especially during the physics class in each grade. Students don't have to memorize anymore to know that resin sunglasses are made this way, which is really more powerful than the teacher has told him thousands of times in class!

Erya also knew in this production process that when the resin is heated, other things must be added, and after curing and molding, it must be polished and polished with special oil. She felt that she had grown in knowledge, and the children who loved science were also amazed, and they were eager to do it themselves, and the teachers would of course give them the opportunity to do it.

We used up all the existing resin and other materials. Erya also proposed epoch-making steam machinery industries such as steam engines, steam rail trains, steam ships, and steam-powered machinery. No matter how this country treats industry and commerce in the future, what Erya wants is whether the Wang family and the children and grandchildren raised by the Wang family can lead the world of industry and commerce, but at least it cannot be out of touch with world industry and commerce. So much so that it has not been able to catch up for hundreds of years. Passive and subject to others everywhere.

In fact, Chen Xin, when they didn't follow Lyon and them overseas, they often heard the lady of the owner say that if they could invent steam power, it would evolve to other heat conversion power, and even develop to electricity. They didn't understand it at the time, but now they do. The thermal power of steam has been discovered overseas, but there is no way to apply it to real life.

It was also because they had often listened to the ladies of the proprietor that they had asked the gentleman who had the intention of inventing the steam engine to do this experiment with him. However, the other party is an aristocratic person, and he does not participate in the research with them who are not nobles.

Fan Yunzhong, who has a good feeling for physics, said to Erya: "The owner lady! The steam thermal power you are talking about has been studied how to be applied to real life. It's just that we haven't had the opportunity to participate. If you ask us to do it now, we can only slowly explore it in a blank slate. At first, they followed the overseas name to call Er Ya Mrs., and they were corrected by Er Ya again and again, and this time they were finally able to call the owner lady smoothly.

The second girl raised her head slightly. He smiled a little smugly: "You don't need to grope slowly." I can give you some drawings on this. Definitely useful! ”

Chen Xin and the others had no doubts about what the lady of the owner said. In the past, when the ladies of the proprietor took courses in physics, nature, geometry, and algebra for a period of time, they would often talk about some natural science things, and when they studied overseas, they were all verified in the textbooks one by one. Therefore, although they are overseas, they still have deep admiration for the lady of the owner.

Fan Yunzhong followed Erya's words and said, "Then let's start making the steam engine you said?" But we weren't prepared at all! ”

"It's okay! I also want to draw some drawings of the steam engine, including the overall appearance, the overall interior, the overall broken surface, the drawings of each spare part, and the combination of various spare parts, and you have to accurately calculate the matching dimensions of these things. Then according to the dimensions you calculated, the blacksmith department will make it. The most important thing you need to do is to deal with some failed problems in the experiment after the accurate calculation and the finished product is out. This is for you top students. It shouldn't be a problem! ”

Fan Yunzhong, Zhao Mingyang, and Liu Jian, a few children who are very researched in physical dynamics, heard this, and began to doubt the lady of the owner who would never doubt it. Isn't it too exaggerated that she would draw things that physicists can't think of in any way that physicists can't come up with? If you want to say that the proprietor lady brags, she is not a person of that quality; To say that it is not bragging, this is too bizarre. However, they are all adults, and even if they have any doubts in their hearts, they will not say it directly. Besides, won't the proprietor find out what the situation is when the proprietor takes out her drawings in a few days?

"Okay! Lady of the Owner! Then we'll wait for your drawings to come out and start again! ”

"I'm afraid it will take a while, but don't be in a hurry. The blacksmith department is also very busy now, and a lot of machinery is waiting for them to cast quickly, and it is useless to be in a hurry. Erya remembered that many of the newly invented machinery that those foreigners in Lyon bought for her were used in her factory. In particular, the sewing machine is much more advanced and easy to use than the old blacksmith I made; The weaving machine is also easier to operate than its own weaving machine, and there is very little waste; The improved sewing machine can also be used in its own machinery and garment factory, and it is currently all hand-piping, which is too time-consuming. There are also shoe-making machines that can be used in shoe factories, and shoe-making machines can also be used in bag-making, and these machines need to be mass-produced.

Because there is a ready-made mold for the sewing machine, as long as the size is modified according to this advanced sewing machine, the production can start immediately. There is also this weaving machine, as long as it is slightly modified, it can also start production immediately. Therefore, the blacksmith department has been very busy since the New Year, and several blacksmith shops in the city that have cooperated are also busy.

Er Ya began to be busy drawing the principle drawings of the engine at home, Chen Xin and they had to translate textbooks, teach students on the other, and help calculate the dimensions of all the spare parts of some relatively difficult machines that need to be mass-produced, so that the craftsman department could make the corresponding molds and then hand them over to the blacksmith department for production.

They are busy, and the craftsman's department, the blacksmith's department is even busier. Of course, it is also because of the efforts of Er Ya and these boys who have achieved something in science that the Wang family's craftsman department and blacksmith department quickly developed into the most advanced and largest machinery manufacturing factory in the Damin Dynasty. Even the Imperial Court Manufacturing Department can't compare with it! However, in order not to cause trouble, the Wang family basically only produces the machinery they need, and never takes outside business, so no one knows the true situation of the Wang family's manufacturing department.

From now on, there are new regulations in the school, and all children can choose to take the road of the imperial examination from the age of fifteen, or to study science and take the road of scientific research, or neither, just like the big brothers and sisters in the past, the school does not interfere with business, martial arts, craftsmen, etc. But there is a strict rule that you are not allowed to drop out of school until the age of fifteen.

Because the subjects are more detailed and the classes are clearly divided, they basically copy the school grade system of later generations. Under the intervention and reform of Chen Xin's teachers, the Wangjiahepu Town School has become more and more perfect, far ahead of the universities of the Damin Dynasty. Of course, some colleges are reluctant to admit it, they think that Hepu Town School is not on the same level as them at all, and seriously accuse Chen Xin of teachers who have returned from overseas for not doing their jobs properly and misleading their children. However, it is useless for them to accuse, as long as the Wang family and the children attending the school can accept it, anyway, the school will not recruit students from the outside world. If someone wants to come in, they won't accept it!

The science teaching in the school, finally no longer have to worry about half a point, before she relied on her memory and some textbooks left to her by foreigners, and pieced together physics, nature, mathematics, and geometry, which has always made her worry about teaching. I'm afraid that if there is something wrong, then it will be called a mistake and a mistake. Now that I have a textbook with regular rules, my heart that has been mentioned for several years has finally settled down, and I sleep sweeter than usual.

Wen Yue came back from practicing martial arts in the morning, and when he saw that his mother hadn't gotten up yet, he couldn't help but ask in his heart: "Dad! Why didn't my mother get up again? Mother is cute and lying in bed this time! ”

Xiaohu was angry: "You don't go to study hard, prepare for the next township exam, and you have the leisure to take care of your mother's affairs here!" ”

Wen Chao, Qingzhu, and Wen Yue all returned to Wang's house with the live-in gentlemen who were invited to the west. The two gentlemen were enshrined by Erya and arranged to teach in the school, and of course several children returned to the school to study. Perhaps Mr. Fan's strict teaching has played a role, and in recent years, the children in the Wang Family School have been admitted to several talents every year. Wen Chao and Qingzhu are no exception, and they have all won the show one after another. It's just that I don't know if the foundation is worse, when I took the township exam, among the candidates of the Wang family, none of them failed to pass the exam. In addition to Anzi and Xiaolong, the descendants of the Wang family can be regarded as lifting people to interrupt the layer.

In fact, Xiaohu and Erya don't care very much that the children must be promoted and jinshi, but now is the time for them to study, so they should study hard, which is their duty as students.

Wen Yue listened to his father's reproach, quit, and shouted aggrievedly: "Dad! How am I meddling? My mother never slept lazy before, but now she can't wake up at every turn, you don't know how to find a doctor to show your mother, and say I'm nosy! You don't care about my mother at all! ”

Xiaohu was shocked when he heard his youngest son call like this: Yes! The daughter-in-law had never slept lazily before, and even when she was pregnant with Wen Chao and Wen Yue before, she had never been so sleepy. But don't you really have something wrong with your body?

Thinking of this, Xiaohu suddenly broke out in a cold sweat, his eyes turned red, and he shouted at Wen Chao and Qingzhu, who were also looking at him in a panic outside: "What are you all standing stupidly for?" Why don't you ride to town and pick up the doctor? Come on! ”

Wen Chao reacted at this time, and responded in a panic: "Yes, yes!" I'll go! "While running to the backyard horse pen to pull the horse.

Qingzhu and Wen Yue anxiously asked Xiaohu, "What about us?" ”

"You go and bring a basin of hot water, I will call your mother up, wash her face, and wait for the doctor to come and check the pulse." Xiaohu hurriedly entered the bedroom while instructing Wen Yue and Qingzhu. (To be continued.) )
