There is an extra group of students for no reason, and they are all the type who can't charge tuition, and Jiang Tian doesn't know what it will become in the future. Pen ~ Fun ~ Pavilion www.biquge.info Fortunately, things in the house have come to an end, and after these days of tossing, the people who should have gone are almost gone, leaving less than a third of the people just to maintain normal operation. So he carried out a redistribution of the people in the house, and the husband, the husband, and the old woman who sprinkled and swept were all available. It also allowed people to re-vacate a small courtyard in the backyard to count as Xiyun's boudoir, and the accommodation conditions of others were also improved. Originally, people thought that Jiang Tian would rebuild the original layout of Yihong Mansion, after all, the original design and planning were not related to the mansion of a second-grade official. But I don't know what Jiang Tian is considering, except for some inappropriate decorations, the room has generally not changed.

"If you tear down the yard and rebuild it, you will need one or two thousand silver, right? Did I take it out? ”

In the afternoon, because Jiang Tian took a day off, Old Man Song sent Song Yi here to ask, and Liu Baokai insisted on following after hearing it. As a result, Huan'er was also making a fuss about coming, so Wu Yuan had no choice but to accompany Wang to appear in Jiang's mansion. A group of people came to visit, but the family members who stayed were startled, usually these masters can jump around, and their own lord's face is really big, so they can visit at the same time.

After listening to Jiang Tian's answer, the pervert who was talking a lot just now to redesign Jiang Mansion was also dumb, the valuation of one or two thousand is still very conservative, if you count some rockeries and water pavilions that decorate the courtyard, it is very common to spend a few thousand taels, with Jiang Tian's salary, even if you have three salaries, you have to save for a few years without eating or drinking, unless they can be filial piety as students.

Song Yi could only sigh when he heard this: "Originally, there were Bing Jing and Carbon Jing, which were a little living money for the Kedao Qingliu. The new dynasty clearly stipulates that gifts between officials shall not exceed ten taels of silver, and the Academy of Sciences is not a yamen that attracts attention. Now, of course, the income has also improved, but it is a bit stretched to buy a house for yourself. ”

Wu Yuan disagreed: "That kind of bad habit is regarded as a corrupt act by Your Majesty, and of course you can't keep it." However, it is reasonable to say that Lord Jiang's official position could not live in such a vast courtyard in the first place, and the existing income is not enough. ”

Song Yi felt a thrill in his heart, how could he forget that Wu Yuan and Zhang Huan were also present? With these two sitting here, of course, you can't speak ill of the new dynasty. Fortunately, the pervert reacted quickly enough and hurriedly played a round: "That's, that's it, this house is rewarded by His Majesty, and the person who can buy such a property in the capital is definitely full of money, and it is reasonable that my brother can't afford to repair the garden." But how did I hear that you're going to reopen your private school recently? ”

In fact, this is the reason why Zhang Huan had to come to visit the teacher, and he quickly pricked up his ears when he had not spoken. Jiang Tian didn't hide from them, but hoped that these people would come to class: "I won't hide it from you, I have this intention." ”

Wu Yuan was strange, he didn't know what kind of medicine was sold in Jiang Tian's gourd: "What does Mr. want?" ”

"There are two main reasons, the first one is to earn some pocket money!" Jiang Tian also said the main purpose first: "The second is that by giving you a few lessons, I found that the explanation of Xinxue in your books is quite messy, even if you read through the whole book, you can only say that you have learned a little understanding, which is why I asked you to take notes in class." But even if any of you succeed in Gokyoin Middle School, it's still hard to be of great use. Not to mention expecting you to invent and create. Therefore, I want to tutor those who can be made alone, and there are many people in this capital who can't enter the Imperial Academy but yearn for new learning, so we must always give students from all over the world a chance to improve. ”

The first reason is Xinyue's thoughts, and the latter one is Jiang Tian's own figure, those four people thought Jiang Tian was too straightforward at first, even if you want to make money, you can't just shout it out, right? But as soon as I listened to the latter words, I directly ignored the front. Many of their textbooks, whether mathematics or physics, were compiled by the emperor, and some missionaries felt that it was too difficult to serve as enlightenment textbooks. But in Jiang Tian's eyes, it is not worth mentioning at all, and after reading through it, it is only half a bottle of water, and it is not considered a qualified graduation in the eyes of others. If anyone else dared to say this, they could angrily denounce him as a bold fanatic, but Jiang Tian said this, and they really didn't have the confidence to refute it.

The temporary coldness did not affect Zhang Huan's curiosity, and as soon as he saw that no one spoke, he hurriedly asked the doubts in his heart: "Why did Mr. say that the things in the book are useless?" ”

Jiang Tian didn't know that this kid was the prince who was fake, so he didn't pay much attention to it: "I heard that this was written by His Majesty, but you also know that my old mentor taught him the art of war, so Xinxue is just a slight mention of dragonflies, and in the eyes of others, of course, it is already erudite." However, when it comes to the rigor and solidity of the new level, I am still a little confident. ”

This is not bragging, the emperor is a soldier who came through the reform just now, and it is estimated that the age is definitely younger than the age of the republic, and the basic knowledge is not very solid due to the influence of the times, otherwise he would not have compiled so many teaching materials that are not next to each other. On the contrary, Jiang Tian was born after the end of the turmoil, and the quality of education and the various extracurricular knowledge he was exposed to were far from being comparable to that predecessor, plus he was an exam-taking talent who had been baptized by the college entrance examination, and his scientific knowledge was of course much higher than that of the current emperor.

Liu Baokai and Song Yi secretly breathed a sigh of relief, fortunately he didn't say anything rebellious, otherwise it would have passed directly into the emperor's ears. But this matter is not over, Zhang Huan doesn't care about Jiang Tian's wild words, anyway, his father said the same: "Then I don't know when Mr. will open this school, and how much is the tuition fee?" ”

Jiang Tian hadn't thought about it yet, and he didn't know how much to charge, and according to his own assumptions, if he wanted to really teach these students well, at least the cost of preparation for teaching aids would not be low: "Not yet, after all, I am not ready here." And even if you collect money, it will vary from person to person, and if those who are dedicated to studying but are shy in their pockets find me, it will naturally be difficult to collect money anymore. ”

Speaking of this, anyone has to say that Jiang Tian is worthy of being a teacher, but no matter what era it is, it is true that a teacher likes those studious students, but even if he is a teacher with noble character, he has to eat, so he will not be soft when he should collect money, otherwise the teacher will starve to death, who will teach the students? On Jiang Tian, what he said was impassioned, but he was sloppy on the key issue of tuition. Except for Zhang Huan, who was still relatively innocent, they were all past the age of naïve and gullible people, and seeing that Jiang Tian didn't want to say the specific amount of money, they couldn't ask questions.

The gossip was almost over, and Song Yi mentioned the main purpose of today: "Speaking of which, in addition to visiting Mr. today, my ancestor also asked me to ask, I wonder how many days Mr. plans to recuperate?" ”

Jiang Tian also guessed Song Yi's intention at the beginning, but he saw that this big group of people was talking about it for a long time without getting serious, and he once had doubts about his own judgment, how could he know that the kind of work in officialdom to nourish his anger was to be able to drag out the business until the end and then talk about it, unless it was a burning eyebrow, no one would go straight to the point and appear that he was not calm enough. Today, Song Yi is also because the real and false princes are here, so he talked about it for a long time, otherwise according to his familiarity with Jiang Tian, there would be no need to bother so much.

"Boss Lao Song is worried, Xiaguan is just a little trivial at home, and there will be your classes tomorrow, so I will definitely return to the mansion tomorrow." Jiang Tian originally wanted to take a day off, and he didn't plan to be absent from work for a long time.

"That's it!" Zhang Huan couldn't hold his breath and was overjoyed: "According to the schedule, it's time to talk about acoustics tomorrow......"

Jiang Tian has always wondered how this textbook was written, and the level is not even as good as junior high school physics, and it is said that it is a natural science class in elementary school. But occasionally there are some physical formulas that need to be memorized, which seems nondescript. Later, he guessed that the emperor who was born as a soldier may not have a solid foundation, and he can only write whatever he remembers, so he is so unsystematic. However, being reminded by Zhang Huan, Jiang Tian remembered that he hadn't prepared for tomorrow's class, and he didn't give a more in-depth explanation of Zhao Zhi's cross talk skills that day, which could be regarded as a day in vain.

After sending off the four gentlemen, Jiang Tian casually opened his handouts, looking at the cursory expression of acoustics in the book, in fact, it can be finished in just a few words, does it mean that he has to say such a simple thing tomorrow morning? Looking at the next chapter, I actually jumped from acoustics to the principle of leverage, which is completely putting the cart before the horse! Jiang Tian pondered, simply removed the string that bound the book completely, and then broke up the pages and rearranged them.

"Brother! How do you tear up a book? As soon as Xi Yun entered the room, she saw a table full of paper, it has become a habit for people in the world to cherish words and paper, and she was naturally surprised to see Jiang Tian behaving like this: "But the rope is broken?" I'll go find another one. ”

Seeing that Xiyun turned around and was about to leave, Jiang Tian hurriedly stopped him: "Slow!" I'm not tearing up the book, but I'm going to reformat it, otherwise the students who teach it will be misguided. ”

Xi Yun didn't understand the reason, anyway, Jiang Tian said this, she absolutely believed it: "That...... What is typography? ”

"Typography...... It's about sorting out the mess and putting it back together. ”

Xiyun still doesn't seem to understand, and she doesn't seem to be entangled in this issue: "Then after you finish typesetting, what will we have at night?" ”

Jiang Tian was stunned for a moment, no one has asked him what to eat at night for so many days, it is all arranged by Xinyue, why would he come to talk about this matter today?

"There's a sister going out tonight, so Sister Xinyue is busy with this matter." The sister in Xiyun's mouth is a certain girl who has been ransomed, and according to the convention, even if she marries someone as a wife, she can only pass by quietly at night.

"So that's ......" Jiang Tian found that there was another person in his life unconsciously, and it was still that kind of silent feeling, and suddenly one day this person was gone, and then he noticed the other party. So he doesn't know whether to face up to other people's feelings now.

There was nothing to say all night, although there was a girl to marry, but there was no need for him, the old man did not need to show up, he quietly came to pick up people in a sedan chair, and disappeared at the end of the alley in the farewell words of many sisters or sincere or false affection. Among the people who saw them off, there were naturally envious eyes, and at the same time, there were also many resentful eyes glancing at Jiang Tian's room. Jiang Tian didn't know that when he faced his students the next day, he reverted to that confident appearance, and those who didn't know the inside story would never have imagined how much melancholy this young official had in his heart. When I went to the classroom, I looked around and found that not only was the attendance rate of the students quite high, but even some researchers who did not have work at hand and other course teachers were preparing to audit, and the spacious classroom was a little crowded.

Song Yi, who was the squad leader, hurriedly stood up and explained: "I heard that Mr. is going to give a new chapter today, and my ancestor ordered everyone in the Academy of Sciences to come here to listen to the lecture except for those who have urgent affairs. ”

Old man Song really doesn't waste resources! At this moment, Jiang Tian had a new understanding of that scientific pioneer in his heart, and the other party must also know how many catties and taels these capable generals under his command had, and letting them come to listen implied the intention of further study. But I originally wanted to rearrange the course, and I'm afraid that I will have to finish the acoustic basics first.

"Okay, according to the textbook, we are going to talk about acoustics, I hope you take good notes, what do you not understand...... Let's talk after class. Dexin, go get a few porcelain plates and a bowl of water......"

In fact, the definition of sound is very simple, it is nothing more than the process of molecular vibration to produce sound waves transmitted in a medium. But to explain such a simple sentence in detail in a language that these people can understand, it is not something that can be explained clearly in three words. Therefore, Jiang Tian only combined the experiment to slowly explain what sound is.

“…… As you saw just now, the amplitude of the vibration is too weak and we can't hear the sound, but there is such a thing as sound, but people can't hear it, so I think the range of sound waves that humans can hear is ......."

Just talking about the content of junior high school made Jiang Tian work hard, not that the students were too stupid to understand, but they always felt plausible and difficult to understand when faced with a bunch of new terms, so Zhang Huan, who was curious, played a very important role at this time.

"Sir, what is a medium?"

"Sir, what do you mean by frequency?"

"What do you mean by radiation, sir?"

"Mr. ......"

Most of the time in a class was spent in Zhang Huan's questions, others did not understand Jiang Tian's explanation, but did not have Zhang Huan's courage to ask everything, especially those auditors, they were afraid of being ridiculed by others for their ignorance, and second, they were afraid that asking too many questions would annoy this Jiang Lord, in case they went to the emperor to complain, they would all be unlucky. Fortunately, Jiang Tian still knows everything, he is mentally prepared for Zhang Huan's questioning spirit, if this kid doesn't ask questions when he is in class one day, it will be the sun coming out in the west.

After a morning of class, Jiang Tian not only did a lot of easy-to-understand experiments, but also wrote a large number of board notes, although they were all written in simplified characters, but these people have been educated in simplified characters, and there is no problem in understanding them. At this moment, many people sighed in their hearts, no wonder Dean Song asked all the people who had nothing to do to come to the audit, at first I thought that the old man was going to take this opportunity to pat the ass, but I didn't expect that this fart didn't need to be patted, the facts are here. Look at this thick note, it is several times more fleshed out than the thin two or three pages of the book, and if all the chapters in the back are like this, I am afraid that the teaching task of this semester will not be completed.

It's time for the end of class, and although the class is very long, there is no opportunity to take a break in between. But all the listeners felt that time flew by, and how could they unconsciously end the morning? The students who are accustomed to rote memorization fell in love with learning for the first time in the illustrated explanations, especially Zhang Huan, who was eager to follow Jiang Tian every day to ask questions anytime and anywhere. But unless he takes the initiative to expose the identity of the crown prince, there is no need to expect such a thing, especially since his father is firmly against him showing off in front of people.

Although the class was over, Jiang Tian did not leave. Instead, he took out his new textbook, which he had rearranged and proofread yesterday: "Through today's lesson, many people have already seen that it may be difficult for you to keep up with my lectures, but it is not your fault. So I revised the textbook last night, and the day after tomorrow I will have a class of mine, and I will reopen physics on that day to fill in the gaps in your basic knowledge. At that time, you should bring more paper of your own, I am afraid that there will be more board books than today. ”

Jiang Tian's words were very simple, but the people below looked at each other, everyone knew that the content of the textbook was very different from what Jiang Tian explained, but because of the special status of the editor-in-chief of the textbook, no one dared to question whether the book was qualified or not. However, he, Lord Jiang, was not afraid of offending His Majesty, and blatantly denied the textbooks compiled by the emperor. Everyone who knew Zhang Huan's identity subconsciously looked at his seat, if this true prince started a surge, even if you are the emperor's junior brother, you can't compare to this own son, right?

As a result, they were disappointed, Zhang Huan was not only not angry, but also stared at the book in Jiang Tian's hand with golden eyes, and couldn't wait to ask: "The textbook in Mr.'s hand has been compiled?" ”

Jiang Tian nodded.

"That'...... The students want to borrow it first, and if you agree, I would like to stone a few copies and send them to the senior brothers here, so as to save everyone trouble. ”

Jiang Tian is not unaware of his little abacus, and he does not hesitate to spend money to print books at his own expense in order to get a sneak peek, but this is also reasonable, studious people are naturally willing to spend a lot of money for a good book. Jiang Tian had no reason to object to this wish.

"Okay, but it's up to you whether to print it or not, but you must give me a complete book back the day after tomorrow when I go to class."

What everyone didn't expect was that this hastily organized textbook had not been changed too much in two hundred years, and it had always been the "Basic Physics" for junior high school students!
