As a salted fish, I was forced to become the teacher of all ages

Speaking of it, this is the hole that Huamanlou dug a few months ago because Huai Anbo went to Lanzhou Mansion to feel depressed, and felt that he was not strong enough.

At that time, when he taught physics, many people didn't take it seriously, but after the carriage developed by Zhao Ren proved the great effect of friction, all colleges began to indulge in research and development, and among them, the first What's more, the Metallurgical Institute of Yiyuan - after all, the bearings were developed by some of them assisting Zhao Ren, and these people not only received a large bonus, but also received a share of the sales of the bearings, which made many of their colleagues jealous up.

Think about it, everyone originally worked together with similar incomes, but suddenly a few people were lucky enough to get some advice from Lord Hou—the matter that Zhao Ren went to discuss with Hua Manlou was recognized as a flower. Manlou's advice - and then he made a fortune, how can other people accept it happily?

Stimulated by great jealousy, Royal Institute of Technology's research and development enthusiasm has never been higher, and the lecture notes of the few physics classes that took the floor upstairs are even handed out in several copies - put them in different places for easy reading, anyway, they Treat these things as treasures, even the wives and sons will not let them touch them.

But the problem is that not everyone has the brains of Zhao Ren, and not everyone can apply the knowledge to practice, so since Huamanlou went to Lanzhou Mansion, the research and development work has stalled again, and many Everyone has a stomach full of questions, just waiting for Hua Manlou to come back and answer them.

But there is only one person in Huamanlou, except for the School of Agriculture and the School of Medicine—the former is established, and the latter has a famous doctor in charge—all schools and departments have different questions and answers, who comes first?

Answering a moment earlier can start work a day earlier, right?And it's not good to procrastinate for the last month and watch other people's bustling day and night!

Therefore, after hearing that Huamanlou came back, everyone came out to rob people.

At this moment, Huamanlou was still outside Xishan, he stepped down from the carriage with a look of surprise and took a look, then asked Wen Liang: "Is this the surprise you mentioned?"

Wen Liang, who got off the carriage with him, smiled and said nothing.

What unfolded in front of Huamanlou was a straight concrete avenue. Although this thing was not unusual in his previous life, it was really a surprise in this year.

This road is not too long, that is, from the outer side of Xishan to the inside of Xishan, and directly to Xishanbo Mansion... Now it is in front of the Hou Mansion, and it may not be as good as a township project in Huamanlou's previous life, but this is the world at any rate. On the first cement road!

You know, before this, there were basically dirt roads everywhere in Xishan. It was muddy on sunny days and rainy days. When you went out for two steps, your feet were covered with a layer of mud, which was extremely heavy. Poe accidentally slipped and fell into the mud, that feeling...

In Huamanlou's previous life, maybe only people who lived in remote rural areas felt deeply about this, but in these years, anyway, Huamanlou just got used to it for a long time.

"Good! This road is well built!" Hua Manlou was extremely happy after walking on the concrete road: "How much money did it take to build it so long? How long did it take? How fast was the road paving?"

In an instant, Hua Manlou wanted to pave this road to the capital, because the road from the capital to Xishan is not easy to walk. Even though there is a horse-drawn carriage with shock absorbers, it is still bumpy enough...

Wen Liang was about to answer, but when he looked up, he saw a large group of people coming from a distance, and he couldn't help but be taken aback: "Why... didn't you say let them greet you, why are there so many people here?"

Huamanlou still doesn't know what kind of treatment he will receive in a while, but at the moment he is in a very good mood: "Welcome as soon as possible, I feel like going home when I see them... Huh? Why does it feel like everyone is full of murderous intent? This Are you going to fight?"

646. I'll Examine You to Death

After a while, Hua Manlou was erected by a few strong men with a confused face, and then stuffed into a special sedan chair by them with a confused face... No, it's more like a sedan chair than a sedan chair. It's a small room or a carriage compartment, because it not only has a sofa in a carriage, but also a tea table with preserved fruit and wine, and even a chamber pot in the corner, which is outrageous.

Hua Manlou was still in a daze, and twenty or thirty strong men lifted the 'sedaner' up, regardless of whether he was a little crazy because of it: it would be better if this thing was regarded as a house, but If you regard it as a sedan chair, then there will be a big problem.

You must know that Dazhao has regulations on the specifications of sedan chairs. For example, folks are only allowed to use two-person sedan chairs, which are called Jianyu; general officials use four-person sedan chairs, which are called soft sedan chairs; , going out of Beijing is eight sedan chairs...

Now these two No. 30 strong men carry sedan chairs that exceed the specifications of ordinary relatives and relatives. If someone uses this to make a fuss, it is disgusting even if Emperor Guangxing doesn't care, and there are also cases in history. Someone was liquidated because of this...

Zhang Juzheng: Why me again?

But before Huamanlou stopped shouting, these strong men ran towards the direction of the University of Science and Technology, yelling. In front of the sedan chair was a group of people who opened the way, and they even created isolation belts on both sides, separating a group of people who seemed very annoyed. People——Hua Manlou could see clearly that those people seemed to be from the University of Science and Technology.

Everyone was arguing, and the quarrel made people dizzy. Hua Manlou yelled out a few times but no one heard him. In the end, he could only lie on the sofa with a wry smile, waiting pitifully weak and helpless for everyone to take him away. carry it back.

Crazy, so crazy...

It wasn't until half an hour later that Hua Manlou was carried into the auditorium, and when he saw the old man whom he had appointed as the dean of the Metallurgical Academy, he finally figured out what happened: "That's why you arrested me in such a hurry. , just to let me give a lecture?"

"Exactly!" The old blacksmith said with a determined face, "Master Hou, time is not waiting for us, please start!"

Hua Manlou looked at the enthusiastic craftsmen who were full of pits and valleys under the stands, and then looked at the chaos at the gate—Smelting Academy relied on its large number of people to block people from other academies. Just in case they came in to interrupt and ask questions related to their department, so at the moment there was endless abuse at the gate.

"Let's begin...Your uncle!" Hua Manlou suddenly became angry: "Young master just came back from the capital, and you didn't even enter the house. You want me to give lectures?"

"But Master Hou..."

Hua Manlou interrupted him: "No but! Liu Tiezhu, you old boy, have you drifted away recently, and you can't figure out your own position? This is a fucking university, not a bandit den!"

The old blacksmith was so scolded that he didn't dare to lift his head. For a while, the craftsmen in the auditorium were also silent, but they didn't know that Huamanlou, who sprayed people, was really aggrieved: I didn't expect it, I didn't expect it, I escaped the emperor and the emperor. Mr. Ge, escaped from that little witty prince, and finally fell into the ocean of the people!

Really can't escape the fate of not being salted fish?

After spraying for a long time, Huamanlou slowly came back to his senses, remembering that all of this was a hole he dug for himself—there was a series of chain reactions on the side of the emperor and Mr. Ge, and it was him in Lanzhou Mansion on the side of the prince He led it by himself, and the grand event in Xishan is because of his own mentality at that time, which was a little wrong...

Thinking of this, Huamanlou was exhausted, and finally looked at the aggrieved Liu Tiezhu and couldn't help sighing: "Okay, let's go! I just came back so hard, let me cultivate for three days! Come here to gather after three days! "

After finishing speaking, he walked off the stage, and added in the middle of the way: "Let people from other colleges come too! What do you look like stopping them?"

Fortunately, the discipline here in Xishan is fairly strict, and everyone makes troubles, but they are restrained in the end. If they really sway each other like the scholars in the capital, where will Emperor Guangxing's face be put?

What?Regardless of the emperor's face?

pull!This is the 'Royal' Institute of Technology!

……

"See see this one day day, what is it called!"

After returning to the Hou Mansion, Hua Manlou's good mood all day was gone.

Huamanlou's original plan was to touch fish for a few days after returning to Xishan, such as walking around in the name of inspection, or in the name of apologizing to drink tea for a long time with the genius doctor Mr. Li - that is Jin'er's grandfather, His Royal Highness the Crown Prince He kidnapped his precious granddaughter to Lanzhou Mansion, and he must give him an explanation when he comes back, right?

And when Moyu finds that He Qing can't sit still and comes to his door, he will give him a little plan for overseas affairs-in fact, the plan is a bit exaggerated, at most it will tell him the approximate location of Oceania, and what to do if he encounters a barbarian. How should unreasonable Westerners deal with it? Anyway, give him the greatest autonomy.

In addition, Huamanlou plans to build a big shed - now that glass is available, other technologies are not a problem, so it's time to try to grow the small half bag of peppers that I can't bear to touch...

You said potatoes and corn?

Isn't that the group of people from the Agricultural College?For a modern person, do you think peppers are more attractive or corn potatoes are more attractive?So the chili is naturally made by myself. I have been greedy for hot pot for a long time!

Of course, it is by no means insignificant to pay attention to things like corn and potatoes, after all, this thing is more related to the national fortune of the flower growers, and it can be used as a prevarication to prevaricate the affairs of Emperor Guangxing and the crown prince—when the time comes You can question them with righteousness and integrity: Do you have people in your heart?

But today's incident ruined all his fishing plans.

They used the inspection as an excuse to catch fish. If you touch it, the eyes of those people are green when they look at themselves. Maybe they were arrested again as soon as they left the house!

After being angry for a while, Huamanlou remained depressed, and finally angered directly from his heart, and he said evilly: "You all love to study, don't you? You all love to study, right? Okay! I'll let you learn." , I imitate you!"

Spreading out a blank piece of paper, Huamanlou recalled it carefully for a while, and then wrote the syllabus with a happy face. The syllabus is as follows:

Positive and negative numbers, rational numbers, linear equations in one variable, linear equations in two variables, factorization, fractions, square roots, Pythagorean theorem...trigonometric functions, plane vectors, space vectors, solid geometry, coordinate systems, parametric equations...

I spent the whole afternoon tinkering with these things, and while tinkering, I muttered: "Mathematics is the foundation of science and engineering. Without mathematics, you study eggs? So three days to learn the entire junior high school course is not too much? Not at all." Points? Such a simple gadget... Yes, there is still an exam, I will test you to death!"

647. Homework

Hua Manlou prepared maliciously and was full of energy, but there were two very painful things that made him completely lose his enthusiasm after a day.

One: Hua Manlou is a liberal arts student, and he can be regarded as a liberal arts student with a wide range of knowledge and a wide range of subjects.

That is to say, he can talk about geography and history at his fingertips, and he can talk about the historical origin of Da Mao and Er Mao's pinching. , But, you can't expect him to be comprehensive, and you can't expect him to be good at mathematics.

Second: Human memory is actually very unreliable.

Huamanlou has been traveling for several years, and he was considered a social animal who had already graduated before time travel, so in this case, how much mathematics knowledge can you expect him to remember from high school?

Some people say that the peak period of many people's life is in high school. There is a reason for this, because some departments of the university do not use high school mathematics at all, such as the law department. , can you expect them to reminisce about the solid geometry of high school as if they were masochistic in their spare time?

And after entering the society, it is even more deceitful, not to mention those whose majors are suitable, and those who are not majored in have to find ways to learn some survival skills-for example, Huamanlouyi, a student who majored in English, graduated from the eighth grade, and the result After graduating, she took the civil service exam. A few years later, she struggled to read the fourth-level books, but her ability to write official documents improved by leaps and bounds...

Therefore, Hua Manlou was horrified to find that when he tried to find the traces of high school mathematics in his mind, there were only one entry left for many things.

Therefore, there is no reason to live and learn forever. Once you give up learning, it is a trivial matter to be out of touch with society, but it is a big thing to become a fool. Except for those things that are truly permanent memory and muscle memory, what you have learned Some things will one day become catalogs, and in the end even catalogs can't be found...

Do not believe?If you don't believe me, the old man who reads a certain code word for a living can count his fucking chapters wrong!

"Ha...haha..." Hua Manlou looked at the lesson plan in front of him with a dazed expression, and after a while, he began to comfort himself: "Well, I still remember junior high school mathematics, this is... well, it's quite useful, right? Hahaha……"

In the afternoon, the whole Hou Mansion heard from Qin'er that his Lord Hou was autistic.

"What is... autistic?"

"Maybe...it's similar to retreat?"

"Oh, it's Master Hou who is enlightening?"

"Is that right? Before that, he got enlightened in the casino, and now he enlightened in the study. Master Hou is really a god."

……

On the day of the promised lecture, Hua Manlou suddenly felt that he was autistic a little early after speaking on the stage for a while-this was a class like a crazy meeting.

"The so-called negative numbers represent the opposite of positive numbers." Hua Manlou called Liu Tiezhu, the dean of the Metallurgical Institute, and asked, "Let me give you an example, old Liu, let me ask you, it takes you ten taels to marry your son. Silver, but you only have eight taels, so you let me borrow two taels, and now I ask you, how much silver do you have after your son marries a wife?"

Liu Tiezhu was stunned and said: "Master Hou, the little old man won't have a son."

Hua Manlou took a deep breath: "I mean, if you have a son, you want to lend me some money for the son's marriage... Do you understand?"

Liu Tiezhu nodded: "Understood, then I won't get any money after marrying his wife."

The corner of Hua Manlou's mouth twitched: "I know you can't get money, what I mean is, if you want to use accounts to represent it, how should you talk about it?"

Liu Tiezhu: "You don't need to keep accounts, the little old man is still not confused, so you can't ignoring the money of Lord Marquis."

Hua Manlou: "...I mean, if you want to keep accounts...forget it, so in a word, the part owed is expressed in arithmetic, and it is called a negative number."

Everyone either seemed to understand but half understood, or nodded blankly.

To be honest, mathematics is a very abstract subject. When learning, not only requires a certain logical ability, but also requires a certain amount of imagination-how much imagination do you expect an old man who has been working hard all his life to have?

This is no different from the mechanics that Huamanlou talked about before, at least people can feel it—watermelons and durians hit their heads, no matter how stupid they are, they will know that the force is applied to their heads...

What's more, although the concept of negative numbers has been established in China as early as the Three Kingdoms period, and there are principles about the addition and subtraction of positive and negative numbers in "Nine Chapters of Arithmetic"-this is much earlier than the West. In the seventh century, many mathematicians in the West did not even recognize negative numbers as numbers, including Pascal, Breinitz and others.

But so much earlier does not mean that people know this concept and method, especially under the imperial examination system of Dazhao, "Nine Chapters of Arithmetic" is even regarded as a miscellaneous book by scholars, and they simply dismiss it.

Even serious scholars are like this, how much research can you expect others to do on this thing?

It has to be said that under the Confucian system, there are too many things buried in the country, not only mathematics, but many other subjects are regarded as strange skills and obscenities-can you believe that the concept of mechanics was proposed in the Mohist classics during the Spring and Autumn and Warring States Periods?

Therefore, it is not only the natural sciences that have been almost stagnant for thousands of years, but the most terrible thing is the problem of thinking patterns, so the lectures that take up the floor are extremely difficult. He had to spend a lot of time to let everyone present accept the 'negative number' This abstract concept even broke down a few times when talking about the negative and the positive - Liu Tiezhu's brain circuit is as hard as ever. His understanding is that Lord Guan borrowed two silver coins for a total of four taels, but it turned out to be Master Hou's downfall. I owe him four taels...

In short, the difficulty of popularizing an abstract concept to these people is roughly equivalent to tutoring an elementary school student with homework, which drove Huamanlou crazy several times.

Of course, this is not to say that it is difficult for everyone to accept, at least Qiaoqiao accepted it very quickly. Several scholars who volunteered to join the School of Physics also nodded frequently, and several young blacksmiths were also thoughtful. The whole building is really going to shut itself down.

But despite this, it is obviously impossible for this group of people to learn the entire junior high school curriculum in three days, let them take the exam...

Might have to wait a few more months.

Wiping the sweat off his brow, Hua Manlou once again got angry from his heart, and the evil turned to his guts: Assign homework!

If you fail the exam, homework can always be assigned, right?Mathematics learning has a long way to go. If you don't strengthen your memory, you will... well, just like Hua Manlou himself. In the end, all you have left in your mind is a directory. How can this bear the name of the Royal Institute of Technology?

At this point, the place where Huamanlou was most criticized by the student party of later generations appeared, and it was the kind recorded in history: the first homework assignment in history was a hundred questions about addition, subtraction, multiplication and division of positive and negative numbers.

(The writing of this chapter is very tangled. In short, it is more reasonable to change it after changing it. The general environment is like this...)

648. Wealth and Insurance

With the lessons learned from the first class, Hua Manlou felt that such a big class would not be taught in the future, at least not in the short term.

But tossing still has to be tossed. After all, this is a university of science and technology, so it can't be justified if the teachers don't know mathematics?

So Hua Manlou decided: "Qiaoqiao, good wife, come, let me tell you about this one-dimensional equation..."

This is by no means flirtatious, mainly because Qiaoqiao is clever and patient. She was the one who taught the mathematics class in school before, so it is only natural for her to continue to teach mathematics—to be able to popularize elementary school mathematics to these big old men. Junior high school mathematics must not be a problem, right?When it comes to teaching, it's better to have a good teacher than to have Lord Hou who is irritable when he doesn't agree with each other, right?

And Qiaoqiao is currently the head of the Department of Mathematics. Although the number of people in the Department of Mathematics is pitifully small, and only a few scholars have filled in, their promotion in this way represents the highest level of improvement in the entire school—first they will drive and then they will be promoted. Yes, everyone can learn it in the end, but Huamanlou only needs to assign homework, and there is no need to make corrections.

What a pleasant thing this is!

All joking aside, to be honest, Qiaoqiao is quite talented in mathematics, at least she can accept these things very quickly, and she can draw inferences from one instance to another - in Hua Manlou's opinion, she is very likely to finish it in a very short period of time Mathematics throughout junior high school.

As for whether she will never return to the road of mathematics in the future, it depends on her intentions, and Hua Manlou doesn't mind it at all.

So it is good to marry more daughters-in-law, and you can leave the annoying things to them... Cough, that is to say, good wife and help, they are better at these minutiae things, such as Xishan's executive warm and cool. It's pretty good, and Hua Manlou can do more things with free hands... well, that's it.

……

He Qing arrived in Xishan when Huamanlou successfully dumped the blame. The moment he saw Huamanlou, he felt a little resentful.

To be honest, whoever comes here will have to complain, the immediate boss is a scam!I agreed to wait for him to arrange, but in the end, I waited and waited for no one!

Hua Manlou didn't care about his little emotions. He took He Qing into the study and said, "Are you going to leave now? Don't you want to rest for a few more days?"

He Qing smiled wryly and said: "Master Hou, you will come back in March, it's almost May now..."

"Isn't it just over a month?" Hua Manlou sneered, "You've been out at sea for at least half a year, so you really don't need to rest for a few more days?"
