After Li Yu finished teaching Guangxu, Xiao De Zhang had been waiting for him.
"Mr. Emperor, you have finished your class." Xiao Dezhang said respectfully. Li Yu was surprised: "Are you waiting for me?"
"Yes," Xiao Dezhang said,
"The Zajia family also wants to listen more to the emperor's teachings." After giving lessons to Guangxu, Xiao Dezhang began to be more respectful to Li Yu.
However, Li Yu didn't believe that Xiao Dezhang really wanted to learn scientific knowledge. He remembered the last time he repaired the gramophone at Cixi's place, and thought he was looking for him for that matter, so he said: "I didn't know who was responsible for the cleaning work at that time. So I just told the truth about the damage." Xiaode Zhang said hurriedly: "Why does the emperor still remember such a trivial matter?" Li Yu said: "Isn't that father-in-law one of yours?" Xiaode Zhang wrote lightly: "Yes, but the Za family has brought many people into the palace, and it is not easy for one out of ten to stand out. Besides, there will be many tests in the palace in the future, and such mistakes can be made, and there is no use in keeping them." Li Yu asked: "That young father-in-law is now..." Xiao Dezhang said casually: "I guess he will never be able to get out of bed in this life. Who told him that he can't even clean the place of the Queen Mother and Lafayette." This kind of little eunuch really cares about Xiao Dezhang It was insignificant and offended the Queen Mother. Xiao Dezhang would never protect him.
The eunuch group itself cannot be judged by common sense. All kinds of contempt, suppression, and struggles are probably the most serious in the palace.
Xiao De Zhang is probably used to it. Moreover, Xiao Dezhang also suffered a lot at the beginning, and his family had a very difficult time after his father died.
When he was 12 years old, he went to a relative's house to pay New Year's greetings during the Spring Festival. He saw a magnificent carriage there and couldn't help but admire it.
Then when the cousin on the side heard this, he mocked: "Your family will never be able to afford such a big car." Unexpectedly, Xiao Dezhang, whose self-esteem was seriously hurt, went home and found out that he could make a fortune by working as a servant in the palace. Shortcut, so he gritted his teeth and committed suicide.
But you can't enter the palace immediately after you leave the palace. He worked as a handyman in a banner family for three years. When a eunuch died in the palace, he filled the vacancy and entered the palace.
I was initially assigned to the teahouse, and the master was a person in the palace.
An old eunuch from "Haha Li" often beat and scolded the young eunuch. Xiao Dezhang later recalled that he was beaten more than 2,000 times in a few months.
Then Xiao Dezhang entered the Nanfu Opera Troupe again. In addition to inviting famous Peking opera actors from outside, such as Tan Peisheng and Yang Xiaolou, Nanfu Opera Troupe also trains young eunuchs to perform on stage.
However, the Nanfu Opera Troupe punished the young eunuch very harshly. After all, they were singing for the Queen Mother and they did not dare to make any mistakes.
These little eunuchs have become monks halfway, and their basic skills cannot be compared to
He is a famous actor in Peking Opera who "comes from a professional background", so his training is very strict. Many young eunuchs were punished here to the extent of being disabled or even dying.
actually
"Haha Li" also had some evil intentions. He wanted to torture Xiao De Zhang to death before sending him to the Nanfu Opera Troupe. Unexpectedly, Xiao De Zhang would reach the peak of his life because of this.
After all, a person who can wield a sword from the palace is really terrifying. Within a few years, Xiao Dezhang was appreciated by Cixi, and soon he rose to prominence and became popular among the eunuchs.
Li Yu didn't want to ask too much about things in the palace. Anyway, he had heard that intrigues in the palace were terrible, and sometimes he wanted to torture others to death.
So he stopped mentioning that matter and asked instead, "What do you want from me, father-in-law?" Xiao De Zhang smiled and said, "I heard that you know the most about Western learning! To be honest, the Za family once went out of the palace to see the foreign buildings in Dongjiaomin Lane. , it’s really beautiful to look at. I’m a Zajia. I like to draw pictures and design houses when I’m free. I just want to ask my husband to help me find some classics on this subject. Is that okay?”
"Architectural design?" Li Yu asked in surprise. Xiao Dezhang said: "So that's the name." Li Yu really didn't expect that Xiao Dezhang had such a hobby. He was a little surprised, but he had no reason to reject him, so he could only say: "I will help you pay attention to what you buy later." Bring on some." Xiaode Zhang said,
"Also, I heard that foreigners use different paper and pens for drawing, or else..." Li Yu also learned drawing geometry in his undergraduate degree in mechanical design. Although he didn't understand architectural design, he was very good at drawing. I still know the picture.
"Okay, I'll take care of it." Xiao Dezhang said gratefully, "Thank you so much, Imperial Master! The Za family will definitely thank you very much!" Li Yu actually saw that Xiao Dezhang wanted to get close to him, so let him go.
After returning home, Li Yu received news that Sweden had remitted 38,000 kronor, which was the royalties for the second edition of "Fractals and Chaos". It was equivalent to almost 5,300 taels of silver. After deducting the handling fee, there was still more than 4,800 taels left.
Sales seem to be good, with more than half of the 30,000 copies sold. Li Yu thought about the possible expenses of going to the United States, so for convenience, he deposited all the money in the bank.
Later, he played several games with Fan Xiren, Feng Zuxun, and He Yujie at the Capital University Hall, and taught them some rules of football.
Fan Xiren loves to play. Not only did he become addicted to board games in the past, but now he feels extremely happy playing football.
"I didn't expect you to be so good at playing!" Fan Xiren said. Li Yu said with a smile: "Combining work and rest, you guys practice hard, and when I come back from the United States, we will form a school football team." Fan Xiren was too interested: "No problem! I will definitely take them to practice hard!" Ding Taoliang knew that Li Yu After going to the United States, he also found him. After all, it was his hometown, and asked: "I heard that you are going to the United States this time with a mission?" Li Yu said, "I'm just making up the number. Anyway, Liang Cheng is there in diplomacy." Sir." Ding Taoliang said: "If it only involves education, the great President of the United States will not stop it." Americans are very proud now, but there is nothing to say, and they also have the capital to be proud.
"I hope so," Li Yu said,
"Although in the future..." Ding Yuliang saw Li Yu pause and continued: "There will definitely be more schools rising in the future." Li Yushun said: "Of course." The handouts were compiled and sent to Zhang Yuanji in Shanghai.
Within a few days, Liang Cheng found him. Historically, Liang Cheng indeed left for the United States to serve as ambassador to the United States at about this time.
Whether now or in the future, the ambassador to the United States is a key position. Fortunately, the Qing government chose the candidate very well this time.
It is very quick to take a ship from Tianjin Port to the west coast of the United States, passing through Japan and taking the northern route, which only takes about three weeks.
Then take a train to the east coast. This is the fastest way, much faster than taking a boat to Europe.
Li Yu had been thinking about what paper to write and submit to the UK on the way, and this time Li Yu paid more attention to it.
His best fields, physics and astronomy, have relatively good directions. Li Yu had some content in mind, including theoretical physics and astrophysics.
Theoretical physics is certainly suitable to be written on a ship. Li Yu felt that it was time to take a big step and write directly about quantum mechanics, which he is best at.
It has been more than a year since I came to this world, and now I have more or less a certain scientific status, and it is almost ready.
As a latecomer, Li Yu knew very well what the basis of quantum mechanics was. ——To put it simply, of course it is
The concept of "quantum" itself. Although this sentence may sound a bit redundant, the concept is really subversive.
This can reflect the biggest difference between mathematics and physics: mathematics is purely abstract, but physics must follow and correctly explain the laws of nature.
Mathematically, there can be infinite latitudes, and there can also be infinitesimally small. But in physics, or in actual nature, it is impossible for anything to be subdivided infinitely. Everything has its smallest unit.
Even time has its smallest unit. In other words, there is a so-called
"Maximum resolution" cannot be infinitely detailed. In quantum mechanics, energy is also emphasized
"One portion." Anyway, no matter what it is, it is an integer multiple of the smallest unit. In fact, just mention it
"Integer multiples",
"One portion at a time" will be a bit like quantum mechanics. But now it’s still quantum mechanics
"Prehistoric stage", even the great god Planck deduced it three years ago
The correct formula for blackbody radiation in "Two Dark Clouds", but it's a pity that he made up the formula... In other words, although the result is right, the process is wrong.
This is very uncomfortable! Because it’s hard to convince. Let’s briefly talk about the problem of black body radiation: At that time, physicists had already obtained an experimental curve of black body radiation phenomenon based on experimental phenomena, so the task was actually to explain why this curve looks like this. It would be best to have a formula.
Planck's formula is derived from this curve, and the formula is in good agreement with the experimental images.
However, as mentioned above, the derivation process is wrong and everyone does not agree with it. In addition, the German physicist Wien used the theory of thermodynamics to derive a Wien formula in 1896, but this formula can only explain the high-frequency stage and does not fit well in the low-frequency stage.
Even so, because of such an incorrect formula, this guy also won the Nobel Prize in 1911... Later, Baron Rayleigh derived a Rayleigh formula that was only consistent at low frequencies, which was not perfect.
And this theory was later used by many science fiction to explain so-called ultraviolet weapons: Because the frequency of ultraviolet rays is high, according to Rayleigh's formula, when the frequency is high, the energy radiation of the black body will tend to infinity.
This is obviously unreasonable. As a physics major, Li Yu is very proficient in correctly deriving the blackbody radiation formula.
In fact, historically this was done by the Indian physicist Bose later. However, Bose did not get the derivation process right, and there were also obvious errors.
In short, Li Yu knows very well that once the correct derivation process of the black body radiation formula is taken out, it will definitely be at the level of a nuclear bomb. No, there is no nuclear bomb yet, then it will be at the level of an earthquake!
It’s too early to tell, but at least Li Yu and Max Planck won the Nobel Prize in 1911.
So it’s really heartbreaking. After all, I am one of the two dark clouds! Li Yu was in the room, spread out his manuscript paper, concentrated on his calculations.
He was really familiar with the process, and his hands didn’t even shake when he wrote it. The paper is not particularly long. The key is that he does not need to write it too long at all.
Li Yu's mathematics and physics are both up to par, and there can be no mistakes. After the ship arrived in San Francisco, that is, San Francisco, Li Yu immediately found the post office and sent the paper to the Royal Society of Science.
Fortunately, the U.S. Post Office also accepts silver dollars, otherwise we would have to go to the bank to exchange dollars. Liang Cheng saw the letter sent by Li Yu and said, "I see you have been calculating things on the boat, and it turns out you have written a scientific paper." Li Yu said, "Idle time is idle, why not do something." Liang Cheng asked : "Another incredible thing?" Li Yu smiled and said, "Let's wait and see."
