The taste of the dim sum is not bad, the nuts, crispy, a bite down, layers of apricot yellow skin crispy spread out and fall into the palm of the hand, one by one as thin as cicada wings. I twisted it and looked at the light, and it was translucent. This workmanship is too peculiar, steamed out is obviously not so sharp, said to be fried in warm oil, but it can't be eaten greasy at all, you have to ask.

Raised the dim sum in his hand and shook it towards Lanling, "How do you do it?" Tell me I'll try it when I go back, it's delicious! ”

"What about you, what's the matter?" Lanling snatched it away, scattered the dregs of dim sum, and said angrily: "Ask you about the drawings, don't ignore them, make it clear!" ”

"This ...... Ah, that's it! patted the placket of his clothes, took out a handkerchief and wiped it, walked over and reached out and touched Lanling's belly, "Nothing abnormal recently, right?" Ever feel like eating something sour? ”

"Die!" Lan Ling pushed me away with both hands and feet, "It's time to have it, I didn't talk to you about this." Count, if you don't want to say it, report it according to your name, anyway, meritorious service and rewards are indispensable. You're a prodigy, and I wouldn't be surprised if you put a great innovation on you, but I'm used to it, and everyone is getting used to it, right? ”

"You can't say that." You have to find a way to stretch the topic apart, and if you only say this, this lie is really not round. Especially Lanling, who is sitting opposite, don't say lying, you can't escape even if you hide it a little, we have a kind of chemistry together, one party is a little crooked, and the other party will have an induction immediately, which is not easy to do. After thinking about it, Shan Tianfang took a dim sum plate and lightly smacked it on the table, "This is a long story." ”

"Say! Less gimmicky. "Lan Ling saw that I was going to start a long story, kicked his shoes, moved the tea bowl and put it to his hand, grabbed a handful of almonds, and lay on the soft couch. When he was done, he pulled a thin blanket to cover himself, "You can start." ”

"Physics, physics, you know?"

Lan Ling nodded, "You talked about it before, and it wasn't as detailed as arithmetic, but I also recorded some of it." ”

pointed to the drawings on the desk, and said softly: "You are too careful." You think that this is the Zhang family brothers who handed me the drawings from the weaving department, I don't deny that there is such a possibility. But I dare to say, you must have seen all the new drawings of the weaving department that I have seen, don't tell me that you didn't install people in the Ministry of Works. ”

Lanling nodded honestly, "That's why I'm wondering, why is the Zhang family kid obviously a weaving person, and he actually took out an object that I haven't seen before." Say! Did the three of them secretly make something new and send it to you? Didn't keep any records in the weaving department at all? ”

Shaking his head calmly, "It's not what you guessed. I'm just studying some knowledge with the Zhang family brothers, and it's generally said that it's Gewu, but it's different from the Gewu that everyone understands as oral transmission of the heart, and we're just going to explore the principles. That's why I call it physics. That's right, Gewu has always been unpopular with scholars, the reason is because it is closely related to traditional handicrafts, and when it comes to Gewu, everyone inevitably thinks of carpenters, masons, blacksmiths, and other professions. High-end is to do some institutional interest-bearing classes. Let the reader understand that there is no great development in learning these, is it just to be a literate carpenter? This kind of psychological discrimination has been generated, and Gewu cannot become a complete discipline, and can only be scattered among the people to become an independent skill to make a living.

This is a strange circle, the general level of education is not high, but the place that looks down on this thing has a relatively high cultural quality and comprehension ability, and there are no elites to study. It can never be a theoretical discipline. But as soon as I explained it, I sublimated the identity of Gewu, which is a principle, exists as a theory, and is a written article that can be formed, and it can be used in the hall and the kitchen, which is something that cultural people like.

I'm proud of my quick statement.,How did I not expect such a grandiose statement before.,Just knowing that people who study Gewu in this era are treated unfairly.,It's very unlikely that you want to promote Gewu as a popular discipline.。 It seems that lying is not always bad.

Here comes the spirit. I took the drawings and climbed in front of the Lanling, in a scholarly tone. "Esoteric disciplines will no longer be called Gewu in the future, we will collectively call them physics. The Zhang brothers found in the weaving department that there was a serious problem in the process of developing a new loom, which was very serious, and it was likely to lead the road of machine development to a dead end. Not only that, if this kind of malaise is not corrected in our Datang, it is likely to restrict the rapid development momentum of the country, and the impact is very bad! After speaking, he secretly looked at Lan Ling's face, very disappointed, and there was not much change.

"Oh?" Lan Ling chuckled, "I know you're making up lies, but since it's so serious, I can put the matter aside for the time being and listen to your shortcomings." ”

"Why don't you trust people?" Helplessly, he sighed cooperatively and asked, "What do you understand as a Gewu?" ”

"I haven't thought about it carefully before, and I've always worked hard to make a living, right?"

"Yes, that's not wrong. But think about it, what if you don't have it? ”

Lan Ling smiled, "How could it not be?" What do we live in? With what? It's all nonsense. ”

"That's right, this means that Gewu, as a discipline closely related to our lives, no one can be separated from it, whether it is your royal family or the hard-working farmers in the grange." Turned over and pulled a soft pillow on it, "Such an important thing, there is no special person to study it, do you say it is a ......?"

"Why not?" Lan Ling interrupted me, "There are so many people in the Ministry of Engineering who study these things, and the opening of the scientific examination has also established a separate discipline for Gewu. ”

"What is the Gewudi? You talk about it. ”

"Xiucai's scientific research is erudite, as soon as you look at it, you are a person who doesn't know books, and erudition contains Gewu, I don't understand what nonsense is about?" Lanling stinked at me, "Next time, I will be laughed at and shameful." ”

", lie to someone. According to last year's provincial examination, how many people took the Xiucai test? Twenty of them? Compared with the Ming Jing and Ming History, the proportion of the toes can be seen, which is the disadvantage. There is also a face to say that he is well-informed, and if he continues like this, he is afraid that he will have to take the Xiucai Department in three or five years. Take a look at the exam questions, what kind of bullshit is examined, there are more than 20 candidates a year for such an important subject, and I am afraid that there is no one who can be retained. Today's engineering and weaving courses. That door is missing a grid? It's all about what to learn, and you don't even know the theoretical knowledge, how can you let everyone be creative? "Righteous indignation is like this, Liu Renliang's impassioned expression was further deduced by me, "Don't say that I laugh at you, it's still sailing, the first time is that we are lucky, don't expect good luck to stick in front of you." The shipbuilders didn't understand why he built it the way he did. One said that it was taught by the master; The loom maker doesn't know how the whole machine works, so it's like this. It's all passed down from generation to generation in such a muddle, and you can still expect a leap forward based on this? ”

"So what do you say the machine works?" Lan Ling laughed, reached out and took the drawing, "You can just tell me the principle of this set of arms, I can listen to it, oh, wait for teaching." ”

Kindness. Wait for her to ask me. The analysis diagram of the arm and torque is drawn, and the truth is analyzed very professionally (high school basic), and the design of what shape can make the torque balance after the calculation of the hinge is clarified, and the method of calculating the golden combination is demonstrated. Divide the most labor-saving proportions.

"Don't doubt it, you can copy so many combinations according to my drawings, and then try it yourself to see if the conclusions I draw from the paper are correct." Pushing the schematic diagram to the stunned Lanling, he was very proud. Ignore her.

In this era, they all rely on groping, they are all painstakingly trying to find a way closest to the right in failure, and even after hundreds of failures, they can't achieve the desired result, and they have never thought of a similar calculation method, and they can roughly demonstrate the process in detail on the drawings, which is a fantasy in Lanling's view.

"You dead man!" Lan Ling threw the legend away, grabbed my neck and slapped me on the back a few times, "That's not what you taught me before!" You said you've taught me something over the years! ”

"Strangled!" Push her away. His neck turned red and he gasped, "Sister, let's die!" ”

"What did you say you taught me?" Lan Ling asked reluctantly, "Why can't I understand what you said at all?" It's obviously a gewu, why do you use arithmetic all the way? Why do you have to look so hard to calculate the way I calculate? ”

"You've just learned a fart," patted his belly proudly and complacently, "and you've learned less than one percent, you know." Learn to get through it if you want to. Hmph, three or five years won't work. I studied optics...... I'll do the math," I snapped my fingers, and I forgot about ...... for eight years of elementary school, nine years of middle school, and several years of college! ”

"Get out!" Lan Ling rode up and gave me a few slams on the buttocks, "I hate to death, and my teeth of hatred are down." Why don't you go to work and become a superintendent? Why don't you go to the weaving department early for guidance? Why don't you say the same thing to me when I record my studies? When you die, are you going to take your knowledge in the coffin? Do you know that doing this is not only sorry for me, but also sorry for your hard work? ”

"If you fight again, you will really bring a coffin, stop!" Life matters, I don't mind bringing a coffin to anything, but I will never give up the chance to live another year. "Eldest sister, everything has to start from the basics, what you teach is a foundation, no matter how profound arithmetic is, it is also an auxiliary discipline, that is, it plays a role as a tool for other disciplines. No matter what you want to learn, arithmetic must first be proficient, and I have done nothing wrong, so it's not right to beat people indiscriminately. ”

"Okay," Lan Ling got down from me, brushing his hair in annoyance, "I'll learn from you for twenty years!" No! From now on, you record textbooks every day, record when you have time, and I will accompany you, record one and engrave one until you die! ”

"What about having a baby?"

"Recording while living!" Lanling turned over, got up and changed his clothes and shoes, "You go back today, I have an idea in my heart, I will enter the palace once, and there will be officials from the Ministry of Industry looking for you later." Also, how long have the three Zhang brothers been studying with you? ”

"It's been a long time, I've been studying knowledge, Eun."

"Okay, don't lie," Lan Ling was busy dressing, and didn't forget to push me, "Since you want to pull the Zhang family along, you can't give credit so indiscriminately." Get up at this point, just teach your skills, Zhangjiadi boys are smart, and they have nothing to teach to teach something on weekdays, which is better than making a merit for no reason. ”

"Why still don't you believe it?" I'm a little anxious, this fight is beaten again and again, in vain!

"I believe it," Lan Ling smiled, "It's the credit of the three of them." Well, I won't get tangled with you. As he spoke, he pulled me up from the soft couch and pushed me out, half-pushing and half-shoving. Before I could go far, Lanling's chariot and honor guard had already left the mansion and rolled east.

Grandiose, tomorrow to test the royal family's guard of honor, we are a marquis, it should be a formal occasion of the guard of honor is not ambiguous, there are not many times available, and it is not a matter of not using it.

You don't have to go to work in agriculture. It is not said that the young superintendent's guard of honor is clearly squeezing the poor superintendent, Lao Liu's pomp and circumstance is very embarrassing, but he has been in a good mood recently, he is busy coming and going every day, planning the independence of the weaving department, and even asking about the location himself. And the news spread, and both the weaving department and the Ministry of Industry began to think about it, and the superintendent could not fight. But the selection of the young prisoner position has become the focus. In this regard, the Inner Government is obviously more organized and disciplined than the Ministry of Industry, and a few people in the Ministry of Industry who can speak have begun to move their minds, and there are examples of agricultural fields, as long as they ascend to this position, their future career will be bright. Not to mention the scenery of Liu and Wang, but the glory and wealth are close at hand.

Those who deliver words and give favors can't get through Lao Liu's side. I, a lazy young eunuch, became the main target of everyone's opening of the joints. Even Ying's wife has a hand in the group to hand over some intentions, and she has to deal with some sudden bribery incidents every day.

"Fight tomorrow...... Forget it, just today. "I called the three cousins of the Zhang family, since Lanling talked about this, it is to leave enough room for the future development of the three brothers of the Zhang family. As a cousin, this little help still has to be helped, not to mention learning, but in the future, if you can have some attainments in physics. With this point, the Zhang family's previous bad luck can also be swept away. Smiled, "There is a problem to be troubled, there is a new discipline that wants to be promoted in the future weaving." As for me, I've also touched a path in the past six months, but I'm so stupid, and I'm bothered to ask a few cousins to help record a textbook, thank you in advance. ”

The three brothers didn't understand what I meant, but since the leader had spoken. It's just a textbook. Not a big deal.

It's warm outside and there's a feldspar case in the yard. Most of the things are handled by Liu Renliang and Chang Gui, and when they don't ask for money, they don't bother me to go out, and they have a lot of time, so they start work in this place. I hurriedly finished recording things according to the middle and high school textbooks, and I couldn't remember the order very well, so I cleaned up my thoughts and started to get busy.

It is very interesting, when recording the textbook, Liu Renliang also asked about it, and after knowing that it was engraved as a textbook, he immediately solemnly gave me a time plan every day, and supervised my work in an all-round way if conditions permitted, and also proposed to personally test the textbook, so as not to delay the recording process.

Fortunately, with Liu Renliang as an eyewitness, it is certain that Brother Zhang will follow me to do academic and local affairs. How comfortable how to come, in the yard, in the test field, while fishing and recording, suddenly became a frequent visitor to the moat, and ran to the hall when it rained and windy, which was spacious.

After recording for a few days, Zhang Yu, Zhang Hui, and Zhang Fu felt a little struggling, not because they were tired of writing, but because the progress was too fast and their comprehension ability could not keep up. For example, there is no accurate way to keep time down to the second, and when it comes to accurate time units, it can only be expressed in percentages, just like one second is equal to 7,200th of an hour, and it seems that various units have to be subdivided, not just weights and measures. As for subjects such as electricity, I don't know how to write, so I'm still lazy to put it first.

Fortunately, the difference in weights and measures does not affect the new base units, and after these base units are determined according to the theorem, the conversion mode remains the same, and a new bottle of old wine is about to be born, which is very exciting.

Zhang Yu, Zhang Hui, Zhang Fu three brothers have never been exposed to such a detailed textbook, as for some things that go against common sense, they are even more interested, here they are recording, and they are doing their best to do some experiments to prove the accuracy of the theory, if you see Zhang Fu limping out, don't be surprised, he must have used himself as an leaning tower to confirm the free fall, a big and a small stone hit the foot is very painful, being able to walk means that the experiment is not going well, I suggest they can go to a higher place to try, In this way, the legs can be broken.

"However, some things are too deep, and it is difficult to achieve correct calculation results without a certain arithmetic foundation, before learning physics, I suggest that the three of you know the basic arithmetic well, so as to further improve your comprehension." Saying that, he handed over the sample book that Lanling gave me to Zhang Yu, "If you don't understand, you can ask me, just don't ask too often." ”

It can be seen that the three brothers are very interested in physics, as long as they make up for the shortcomings in mathematics, with the Zhang family's diligent style and excellent genes, with this basic knowledge of physics, maybe there will really be a character like Newton in the future. Oh, it should be better than Newton, at least they don't have to spend half their lives proving the existence of God.

Knowledge, Lanling is looking forward to it, but when I told her that these have to start with the doll, Lanling is obviously a little unnatural, no one's doll has the conditions to learn this, who to learn? What about teachers? I?

"It's not a matter of one person or two, there is only one way to make physics thrive, and to put such a subject in the scientific examination, so that everyone knows the benefits of learning this thing."

"Yes," Lan Ling nodded, "I will go to Xinyuan tomorrow, and Li Shi wants to talk to you about the next thing...... Physics topics. ”

"You took the book out so quickly for others to read? I haven't finished recording yet. Be careful of allowing others to copy the infringement. ”
