Lu Bicheng felt distracted and was not in the mood to study whether the emperor wore clothes in the fairy tale he was translating today, so he decided to find an excuse to go back and take a look.
However, due to the lack of a good reason, Qiu Jin's sharp eyesight immediately understood her thoughts.
He pulled her to find a newsboy: "Has today's Ta Kung Pao come out?"
The newsboy raised a stack of newspapers in his hand: "Fresh! Guess what? Since our Imperial Master wrote articles again, many Germans have been unhappy! The counselors of the German Embassy have to inform the court and do not allow the Imperial Master to
Insulting the sages of Germany again."
Lu Bicheng grabbed the newspaper: "It's really a big deal! I have to inform him quickly. Sister, I'll go back first!"
Qiu Jin watched her leave, smiled and shook her head, took out her money bag, and then said to the newsboy: "This is 20 cents, give me a share."
——
At home, Li Yu finally finished writing this essay about "Maxwell's Demon".
All are analyzed using Boltzmann's theory and Planck's epoch-making quantum theory.
Of course, he will not bring out the uncertainty principle yet, it is too early.
However, explaining Maxwell's Demon cannot be separated from "entropy", so Li Yu asked later generations to create the Shannon Information Entropy Theory specifically for Maxwell's Demon, which was released slightly ahead of schedule.
But limited by the times, he did not write in too detail.
But "information" also has entropy, which is shocking enough.
The specific content is more complicated. To put it simply, if a "Maxwell's Demon" really exists, if it wants to obtain information about the speed of molecular motion, it needs to consume energy, which is an increase in entropy.
Therefore, it is impossible for hot air to naturally become hotter and cold air to become colder.
Otherwise, if it were so powerful, humans wouldn't have to invent water pumps and refrigerators.
Of course, the article is still relatively advanced. Fortunately, Li Yu has already written an extended article on the entropy increase related to the second law of thermodynamics, extending the entropy increase principle to all walks of life and laying a certain theoretical foundation.
The principle of entropy increase is originally a super epoch-making advanced theory in later generations. It happens to be extended from the thermodynamic theory that is relatively acceptable to all walks of life, so the academic community will not conflict with it.
After finishing writing, Li Yu felt more comfortable and got up to mail it out.
As soon as I raised my head, I saw Lu Bicheng coming in.
"Something big has happened!" Lu Bicheng said anxiously, "Look! The Ta Kung Pao says that many Germans are going to make trouble for you! Hey, I've said it before, it's not a good thing to mess with foreigners!"
Li Yu laughed and said: "I thought it was a big deal, don't worry. Debates are allowed in the court, so why can't I just write an article to refute it? They are just a little unhappy. If they don't like it, just go ahead. I can't care about it.
."
"But they still want to send a note to the court, saying that you have insulted the German sages." Lu Bicheng said.
"I'm insulting? These mediocre people obviously don't understand the truth and they are insulting their own people." Li Yu said indifferently.
"besides……"
Li Yu interrupted her: "Okay, okay, no need to make a fuss. If they really want to scold me, they should first understand the paper in my hand!"
Lu Bicheng warned: "You must never attack their sages again."
"It's there!" Li Yu was very confident, "I'll show it to you."
Li Yu wanted to dispel her doubts.
But as soon as I got up, I heard a stabbing sound.
Wow! The table turned out to have rough edges, and my pants were instantly torn open with a big gaping hole.
Fortunately, I didn't tear it all apart, but after all, there are no underwear yet - underwear will not appear until at least 30 years later.
Lu Bicheng turned around quickly and covered her face.
Li Yu was very embarrassed. He was really uncomfortable without underwear, and he was even more uncomfortable with such anti-human things like the crotchless pants of the Qing Dynasty.
The atmosphere instantly became extremely cold, and neither of them knew how to ease the atmosphere.
Suddenly Konoe Akiyuki came into the courtyard and said: "Mr. Li Yu, I have read several introductory textbooks you gave me before, and also taught other students. Can you borrow some more profound books now? We can't wait.
Enter the factory for actual combat.”
Li Yu was surprised: "So fast? It seems that I underestimated you. It just so happened that I brought back some of the latest books from the university hall. I will give them to you... I will give them to you another day."
Konoe Akiyuki looked at the bookshelf in the room: "Didn't you tell us to show us those practical books on mechanics? They are right there. Now I think it's ok."
"Then you can come in and get it yourself." Li Yu couldn't stand up now.
Konoe Aki glanced at Lu Bicheng next to him, not knowing why, but he still walked into the room and took out a few books from the bookshelf.
"Let me sign the loan book." Konoe Akiyuki came to Li Yu's desk.
Li Yu had no choice. The table was now full of manuscript papers and quite messy, so he had to find them by himself.
He had no choice but to clamp his legs together, then leaned forward and took out a pamphlet: "Here you go."
Konoe Akiyuki's eyes were so sharp that she immediately noticed something wrong with his clothes. Then thinking of the red-faced Lu Bicheng in the corner, she seemed to understand something and hurriedly signed: "I'm sorry, sir, for bothering you."
Li Yu said: "No, no interruption, what are you disturbing?"
However, Konoe Aki quickly exited the room: "I'm leaving now."
As soon as I walked out of the door, I raised the corner of my mouth and my confidence increased greatly: Just play this game in broad daylight. It seems that no matter how smart the brain is, it is just an animal that thinks with its lower body!
There were only two people left in the room again. Lu Bicheng broke the embarrassment and said: "Well, can I make up for you?"
Li Yu said: "No, no need..."
"The material seems to be of high quality. If you have money, you can't waste it like this." Lu Bicheng said.
How does this sound like he is educating himself? However, Li Yu feels that he really needs to make up for it. The materials of Xiangyi Hao are first-class.
"Then let me make up for it."
Lu Bicheng asked: "What, do you still want to be a female celebrity?"
"Uh, no."
"That's it! Let me do it." Lu Bicheng said.
Li Yu suddenly remembered: "By the way, there is a machine now that can mend clothes very quickly."
"There is also a machine that specializes in repairing clothes?" Lu Bicheng had obviously never heard of it.
"Some are called sewing machines, which can be called home travel. Oh no, they are the most powerful auxiliary tool for home celebrities." Li Yu said.
"Sewing machine?" Lu Bicheng said, "I have only heard of looms."
"It's different. It has needles. Once you thread the thread, you can mend clothes by pedaling. It's much more efficient!"
Li Yu demonstrated it to her as he spoke, but as soon as he raised his hand, the torn clothes fell down again, so he had to lift them up again.
Lu Bicheng turned around again: "You, you should change your clothes first."
Li Yu said: "Fortunately, I have quick hands."
Lu Bicheng snorted, "If you don't have quick eyes, I will treat you as the emperor."
Li Yu wondered: "What emperor?"
Lu Bicheng said: "The emperor's new clothes."
Li Yu's eyebrows jumped. He stopped guessing and quickly changed his clothes.
Sure enough, it would be more neat to wear a suit.
Li Yu came back and said, "I'm going to send a letter. How about taking you to see the sewing machine?"
Lu Bicheng was really interested, "I'd like to take a look."
The two went to the Qing Post Office first, and Li Yu took out 10 silver coins and letters.
Lu Bicheng was surprised: "It costs so much money to send a letter? It's too extravagant!"
Li Yu smiled and said: "It's indeed a bit expensive, but there's nothing I can do about it."
When the postman saw the name Li Yu filled in, he said to him: "There happens to be a letter sent to you from Germany. Let's take it together."
Li Yu took the letter and saw the name "Einstein". It was amazing!
He couldn't wait to take it apart and look at it. When he discovered the mass-energy formula, he was very shocked.
In any case, it is amazing to have such a super theory in the early twentieth century.
Moreover, this handwritten letter showing the mass-energy formula for the first time can be said to be priceless.
Later, Einstein's manuscripts were auctioned for tens of millions of euros, and every word was truly gold.
Lu Bicheng asked curiously: "What's wrong with you? Are you breathing quickly?"
Li Yu took a deep breath: "This is something groundbreaking, I..."
He suddenly remembered that he wanted to buy a sewing machine, so he had to put aside the important event of creating something new.
Li Yu's heart was racing in the carriage, and he couldn't help but think about how to reply to the letter.
On the opposite side, Lu Bicheng saw that he didn't say a word, thinking that he was still embarrassed about his pants.
They came to Qiluofu Foreign Trade Co., Ltd. in Dongjiaomin Lane. Today, the manager of the foreign trade company is also a German.
Li Yu has been here before, and the boss recognized him at a glance.
"Mr. Li Yu, I have read the newspapers these days. Why do you talk so much about our country's great philosopher?" the boss couldn't help but ask.
Li Yu had no choice but to explain: "It's just some routine discussions. Does the boss think there is something wrong with what I said?"
The boss thought for a while: "I don't seem to see any problem. To be honest, I don't understand advanced knowledge and I just came to the capital to do business. But they are all talking about your views in the newspapers, so I have to try to read them.
one time."
Li Yu asked: "Have you read any of your own thoughts? Never listen to other people's words."
The boss said: "Actually, I can't even read Hegel, let alone Clausius, who later studied thermodynamics. But out of my inner tendency, I still think our sages are right."
Li Yu sighed: "Then you should really read the article I wrote carefully. I am not the only one who opposes it. You Germans yourself are also arguing."
The boss said: "Maybe, but please don't blame me for speaking out. I always feel that the Chinese should not be allowed to intervene in the debates between Germans."
Lu Bicheng said angrily: "Can't you say you're wrong?"
The boss scratched his head: "It's just my inner thoughts."
Li Yu grabbed Lu Bicheng and said, "It doesn't matter. There is no need to fight over this trivial matter."
The boss suddenly said: "But I think the Imperial Master is still qualified. With your achievements, you can criticize everyone."
The boss listed Li Yu alone, of course because of his unprecedented achievements in the scientific world.
However, Li Yu also has this exclusive sense of respect, "I don't want to criticize anyone, but Mr. De Cuilin should not insult our Chinese sages first."
The boss knew that the matter was unjust, so he had to say: "I think Mr. De Cuilin doesn't know China well enough."
Li Yu didn't want to talk about this anymore, so he pointed to a few sewing machines and said, "Let's talk about business. How to sell sewing machines?"
Of course, the boss doesn't want to waste time on thinking, and is more willing to sell goods. He is a fool if he doesn't make money if he has money. "50 silver yuan per unit."
Li Yu said: "I will buy two."
He threw down the silver coins, asked the men to load the carriage and went home.
There are no beginners in sewing machines, and Lu Bicheng was able to master the skills of using them quickly.
It is true that Li Yu had never been exposed to needlework, and even seeing a sewing machine in his previous life only had a vague memory when he was very young.
But it is said that in the early years, this gadget was one of the "three essential items" for the family along with watches and bicycles.
While Lu Bicheng was working on her work, Fengling came back from shopping for groceries. When she saw this scene, she rushed over and said, "Grandma, how can I bother you to do such a small thing yourself?"
Lu Bicheng raised her head and asked, "What kind of grandma?"
Fengling said: "In short, this is what a servant like me should do."
Lu Bicheng said: "I am a pretty good actress, but you are not necessarily better than me."
Fengling said: "Of course, how can I compare to you!"
Lu Bicheng said: "Also, your husband said that we should be equal and don't call ourselves slaves."
Fengling said: "What grandma taught me is, wait, why is this our family?"
Zhao Qian coughed outside, and Fengling finally reacted, smiled and said, "I, I will go to the kitchen to cook first. You must not leave."
Fengling went out and pinched Zhao Qian: "Why are you coughing, you little bastard? You're so stupid?"
Zhao Qian was in pain: "There is a Jinshi master who wants to find our master."
"Master Jinshi?" Fengling then saw someone standing at the door.
The one who came was Zhu Guozhen, the one who was inexplicably replaced as the top candidate in this year's imperial examination.
"Xiaosheng Zhu Guozhen came here to pay a visit to the emperor's master."
Fengling hurriedly said: "Come in quickly, I happen to be fine now."
Then he quickly asked Zhao Qian to tell Li Yu.
Zhu Guozhen was still a second-class Jinshi. In the feudal era, his status was not low.
Li Yu came out and said, "Why did brother Xingtai (Zhu Guozhen) suddenly come to my humble home?"
Zhu Guozhen said with a smile: "The Emperor's residence is not a humble residence. I remember that it was the residence of Rong Zhongtang before."
After Li Yu brought him to the hall, Zhu Guozhen said: "I came here because I want to join the emperor. I read in the newspaper that you want to recruit people to build a new enterprise. I am very interested."
Li Yu was stunned: "This is not an official career."
Zhu Guozhen said: "I know, but Zhang Jian, the number one scholar, can do business, can't I?"
"Yes, yes..." Li Yu said.
"That's it!" Zhu Guozhen's attitude turned out to be very firm, "To be honest, I have read most of the books on various Western subjects you gave me, and I have benefited a lot. Only then did I realize that I am still so far away from the truth of the world.
Then I suddenly had the idea of following you, Imperial Master, to have some adventures."
Zhu Guozhen was talking eloquently, and Li Yu didn't expect that he would be so interested in mechanics and chemistry.
It seems that those who were the first to come into contact with Western science in China were basically like this.
After all, chemistry is relatively easy to learn and interesting; while mechanics represents the industrial revolution to a large extent.
Li Yu seemed unable to refuse: "Well, since Brother Xingtai has made up his mind, of course I welcome it."
