As long as Li Yu returns to Beijing, he still has to report and then go to teach Guangxu a few lessons.
It is difficult to understand Guangxu's current mood. Sometimes he is high-spirited, and sometimes he is depressed.
Of course, it can no longer be the so-called emperor's mental tricks, but more caused by mental torture.
Every lecture Li Yu brought was written with a pen, which led Guangxu to start practicing hard-pen calligraphy.
When Li Yu arrived in Yingtai, Yu Deling had just finished giving him English lessons, and Guangxu was practicing calligraphy with an American Weidiwen brand ink pen.
If you want to write in English, you can only use a pen.
The Welden fountain pen is also a big brand at present, and many international treaties were even signed with this pen. For example, the Treaty of Portsmouth after the Russo-Japanese War and the Peace Treaty of Versailles after the end of World War I.
It's just that Guangxu's writing is not very good at present, and he has no chance to use this pen to sign any important documents.
Yudeling walked out of the hall and bumped into Li Yu.
Li Yu asked: "How is the emperor's mood today?"
——After all, he is not an ordinary student. He has to understand Guangxu’s mood in advance so that he can temporarily adjust his teaching mode.
Yu Deling said: "I can't tell, but today when I showed the emperor some articles by the thinkers of the Renaissance period in England and France, I don't know if it touched him. He suddenly said to me, 'I intend to revitalize China, but you know that I can't make the decision.
, it can’t be as good as my ambition, how can I dare to accept it in this case?”
Yudeling squinted his eyes and looked at Eunuch Cui who was standing next to him with his hands hanging down.
Cixi was really vicious. Eunuch Cui once threw Concubine Zhen into a well with his own hands. Guangxu hated him with all his heart.
Now that he was asked to monitor Guangxu specifically, he was sure that Eunuch Cui would work hard.
In the palace, Li Yu knew that Guangxu's words were indeed a bit sensitive, so he could only remain silent.
When Li Yu was in class, he taught Guangxu some popular theories related to steam engines. They were all relatively simple contents, still like popular science.
Guangxu gathered himself together, and after listening to Li Yu, he said: "It turns out that what can make a huge train run is the steam generated by such soft water!"
Then he raised his teacup and said, "Is it like this water vapor?"
Li Yu said: "Things are the same thing, but the specific differences are very big."
"The same is true for ships on the sea?" Guangxu asked.
Li Yu nodded: "That's right."
Guangxu thought deeply: "The ancients have not deceived me. It is true that water can carry a boat and capsize it. Four ounces of water can only lift a thousand catties."
He simply could not have imagined that later generations even jokingly said that "the end of technology is boiling water." Even nuclear power plants will eventually boil water.
But there was no way to explain this to him.
Guangxu felt that he had many questions and wanted to continue asking Li Yu, but suddenly Eunuch Cui next to him interrupted: "Your Majesty, the time has come."
Guangxu grinned. He wanted to have an attack but held back: after yelling at Li Lianying last time, he didn't have a good meal for several days.
He immediately became a little decadent. He looked like a king and couldn't even control a few minions.
Guangxu waved his hand helplessly: "You all should step aside."
Li Yu left Yingtai, mounted his horse and prepared to return to Dongchang Hutong.
But Eunuch Cui stopped him and said, "Master Imperial, you should be more careful in class in the future."
Li Yu held the reins and said, "Why do you say this, father-in-law?"
Eunuch Cui said: "Don't let the emperor think that foreign things are so simple. It will only make him have some bad thoughts."
Li Yu was completely explaining complex things in a simple way, which was the most conventional and effective way when he was in school, so he said: "Eunuch Cui, foreigners' things are not so unattainable."
Cui Eunuch smiled and said: "This is not what the Za family wants to bring to you. You can think about it yourself."
Li Yu got off his horse and took out five two hundred taels of silver notes from his arms: "Eunuch Cui, I hope you can give me some advice."
Cui Eunuch looked at the amount of the banknote, took it, carefully folded it and put it in his arms, and then whispered: "You rented Rongfu, some people can't stand it. After all, there are many adults living around, so be careful.
"
Li Yu raised his eyebrows: "It's all normal business, there is a contract."
"Normal business?" Eunuch Cui chuckled, "Emperor Master, sometimes it's too normal to be abnormal. And you also do such a big deal through the Ministry of Commerce, so everyone's eyes are focused on it."
Eunuch Cui clasped his fists and said, "This is the end of my talk, let's take our leave."
Li Yu sighed. He knew that it was not easy to do things in the late Qing Dynasty, but he had an arrow on the string and had to take action.
It seems that my own resistance comes not only from the Japanese, but also from domestic problems that cannot be ignored.
If we talk about the more positive side, it is that we have relatively strong backing support.
However, Li Yu guessed that what Cui Eunuch said must mean that Yuan Shikai himself was deeply involved in the struggle of the court.
But Li Yu always knew that Yuan Shikai would have the last laugh.
For the time being, we can only think so optimistically. As for how the situation will develop, we cannot predict how the situation will develop. We can only adapt to the situation and adapt to the situation.
Although the business environment is not good, because there are people in the court, the progress is not slow.
Xu Shichang has even arranged for people to prepare the road and prepare to set up a relatively simple train stopping platform to facilitate future travel.
Song Jiashu also transferred a batch of machinery from the Port of Singapore. From the current point of view, it is still relatively advanced equipment.
Li Yu contacted the employees at the Tianjin Machinery Manufacturing Bureau through Tang Shaoyi and transferred a batch over.
During the Eight-Power Allied Forces period, the Tianjin Machinery Manufacturing Bureau was destroyed by the war, and many people have been unemployed for a long time.
The Tianjin Machinery Manufacturing Bureau is not small, with a conservative estimate of two to three thousand employees. However, like the Jiangnan Manufacturing Bureau, it is mainly engaged in arms production.
But it also built ships. Cixi’s yacht in the Summer Palace Lake was manufactured by Tianjin Machinery Manufacturing Bureau.
There are even submarines.
Therefore, employees in the manufacturing bureau already have certain technical accomplishments.
It is a pity that Tianjin suffered a great impact during the Eight-Nation Allied Forces in the past few years. Coupled with the death of Li Hongzhang, the Tianjin Machinery Manufacturing Bureau was unable to reopen.
After Zhou Xuexi learned the news, he immediately brought a group of people from Tianjin Machinery Manufacturing Bureau to find Li Yu.
Zhou Xuexi is from Beiyang and is a subordinate of Yuan Shikai. They had met before when they went to Japan to participate in the Quanye Expo.
"Master Imperial, I almost don't recognize you when we meet again," Zhou Xuexi said.
Li Yu is now wearing a short hair suit and is obviously two people, so he said: "People can't change. For such a small matter, I have to trouble Mr. Zhou to go there in person."
Zhou Xuexi said: "This is no small matter. Now everyone in Jinmen is talking about you."
Li Yu knew it was about arguing with the Germans and said, "I'm just doing something right."
Zhou Xuexi said: "The emperor's master can be called the benchmark for facing the wind. However, if a tree is as beautiful as the forest, the wind will destroy it. The emperor's master is better to be careful."
Li Yu thought of what Eunuch Cui said today, nodded and said, "Thank you, sir, for reminding me."
Zhou Xuexi continued: "Be cautious, and the emperor's master does not need to be afraid of his hands and feet. Governor Yuan asked me to tell you that no matter what, he will support the emperor's master."
Yuan Shikai is now implementing the New Deal in Tianjin and is also vigorously developing modern enterprises. A lot of textile factories, cement factories, mining factories, and paper mills have been built.
But in terms of technology and product quality, it can only be considered at the beginning.
However, it can be regarded as laying some foundation for Tianjin's industry again. Zhou Xuexi will benefit a lot from becoming a northern industrial giant in the future.
Although Yuan Shikai's later reputation was not very good, he was indeed a truly capable minister among the ministers in the late Qing Dynasty.
Li Yu cupped his fists and said, "Thank you Governor Yuan for me."
Zhou Xuexi pointed to the more than 20 people behind him: "They were all workers of Tianjin Machinery Manufacturing Bureau back then. Many of them are veteran technicians who have been working for more than ten years. And according to Tang Daotai's instructions, I specially selected those who are familiar with machines."
Li Yu said: "I can only say thank you so much again."
Zhou Xuexi said: "You don't need to thank me. I was just ordered to establish the Zhili Craft School this year to train technical personnel. I will recruit more of my students when the time comes."
Li Yu said with a smile: "There is a huge shortage of talent, and there will be as many as there are available."
Li Yu took this group of workers to the factory to look at the equipment imported by Song Jiashu. They were all veteran workers and were not slow to get started.
Li Yu also knew mechanics, so he took out some drawings he drew and asked them to make simple modifications according to the drawings.
Even though they didn't know how to build machinery, they were able to understand the drawings even though they maintained the manufacturing bureau's machines every day.
Li Yu left several students who were interested in mechanics to study with them.
——
After returning home, Li Yu wrote a reply to Einstein.
What puzzled Einstein the most was the equal sign "=", and it was particularly confusing.
Of course Li Yu understood what was going on, so he wrote:
"Dear Mr. Einstein, your equations are truly amazing, simple and beautiful. This is the most fascinating part of physics.
But I think it does not mean that energy and mass can be converted into each other as stated in your letter. The more essential explanation should be that mass and energy themselves are the same thing.
Just like a coin, it's two sides of the same object!"
Because the article was short and there was no formula, Li Yu sent it directly to Bern, Switzerland in the form of a telegram.
But even though it is short, the key points are stated.
It is said that the concept of "mass and energy are the same thing" is very explosive.
When most people see the mass-energy equation, their first impression is that it is the mutual conversion of mass and energy.
Many people even misunderstand that Einstein developed the atomic bomb through the mass-energy equation.
Of course this is obviously wrong.
The atomic bomb was only available in 1945, and Einstein proposed the special theory of relativity in 1905. There was a 40-year gap between the two, and there were quite a few technological iterations during this period.
Of course, the special theory of relativity does provide a strong theoretical basis for the development of atomic bombs.
But really, it should be attributed to the rapid progress of atomic physics.
Einstein's only help for the atomic bomb may have been that he wrote a letter to the then US President Roosevelt in 1939. The general content was that he should hurry up and research the atomic bomb. It would be bad if Hitler developed it.
But even so, the US government did not pay attention to it.
At the beginning, only 6,000 US dollars were given to the research and development of the atomic bomb. This amount of money could not do anything, and it was not even enough to pay the scientific researchers.
Later, it was Japan who thought of an excellent strategy and attacked Pearl Harbor, which attracted the attention of the Americans and launched the famous "Manhattan Project".
And this has nothing to do with Einstein, because Einstein was anti-war almost all his life.
He just wants to be a pure scientist, how can he directly participate in the development of weapons?
——
Since Fengling was also a researcher now and was working with Ding Deshan on the development of "new pastries", she did not have time to send him a telegram, so Li Yu had to send the telegram himself.
I haven’t been in contact with him for a long time and I am very unfamiliar with him. It took me a long time to finish just one message.
Li Yu stretched himself and sighed that practice makes perfect.
The next day, Lu Bicheng found Li Yu with the manuscript of the Star Wars prequel.
"I have completed the polishing and revision." Lu Bicheng said as he put down a thick stack of manuscript paper.
Li Yu picked it up and looked at it, and Lu Bicheng actually insisted on writing it with a pen. Although the handwriting was not that beautiful, it was all Chinese characters. People with a strong foundation in soft-pen calligraphy would not be slow to pick up hard-pen calligraphy.
Li Yu praised: "Run, it's so moist!"
Lu Bicheng asked: "Do you want to give it to Miss De Ling for translation?"
Li Yu said: "Yes, you have to believe me. Only Chinese people can truly translate articles written by Chinese people. When the time comes, let foreigners translate them into other languages based on English, and they will not lose too much of the original style."
Lu Bicheng whispered: "I understand."
Li Yu didn't think much and immediately gave the manuscript to Yu Deling.
Yu Deling smiled and said: "I have been waiting for the follow-up for a long time. It is really fast."
"By the way," Li Yu asked again, "Has there been anything detrimental to me in the DPRK recently?"
Yu Deling thought for a while and said: "I have always been with the Queen Mother in Xiyuan. I cannot be present in the discussions about the political situation, but I will pay more indirect attention. What, is there any movement?"
Li Yu said: "Not yet. I hope there won't be any problems in the future. I don't want to get too entangled with those courtiers."
Fortunately, there was Yu Deling, an informant, by Cixi's side.
While Yu Deling was busy translating, Li Yu's article on Maxwell's Demon was also sent to the United States and published in the latest issue of Science.
The American Association for the Advancement of Science finds Li Yu's creative ability so incredible that he almost single-handedly pushed Science, a magazine that had been neglected, to the top of the industry.
It's a miracle!
They now devote most of their energy to the operation of this magazine.
——Of course Li Yu needs to work hard, after all, it is his own magazine...
Let’s just talk about this article. Although no one can explain Maxwell’s demon now, one glance at the article shows that Li Yu completely adopted Boltzmann’s theory of using statistical methods to study molecules.
From the perspective of later generations, this is a completely correct path. Because there are no absolutes in the microscopic field, statistics and probability theory must be used for research.
But at the beginning of the twentieth century, the scientific community was really unable to accept these two theories into sacred physics.
At this time, many physicists believe that statistics is for economic and social science research, and probability theory is for gambling. How can it be related to high-level physics?
It’s just a joke, okay?
But Li Yu's reputation in the scientific community is indeed too great now. His previous papers were not only shocking, but also faultless.
Moreover, this paper is in Li Yu's consistent style, with detailed physical explanations and extremely rigorous mathematical derivation.
I have said several times that current physicists are generally not very good at mathematics.
Of course, it's not that they can't understand it, it's simply because physics at this time didn't pay enough attention to mathematics.
He is as powerful as Einstein, but his mathematical skills are also very worrying.
Therefore, even if you are a physics researcher, understanding it requires a lot of brain cells to study the mathematical part.
But it is precisely because of this that Li Yu's paper can withstand debates from all walks of life.
