Chapter 170: Bring out the killer weapon of quantum mechanics
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 Za family also wants to listen more to the emperor's teachings."
After giving lessons to Guangxu, Xiaode Zhang also 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 house, 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 there are many people brought into the palace by the Za family. 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 this kind of mistake can be made.
It’s of no use.”
Li Yu asked: "That little father-in-law is now..."
Xiao Dezhang said casually: "I will probably never get out of bed in this life. Who can tell him that he can't even clean the place of the Queen Mother and Lafayette."
This kind of little eunuch is indeed of no importance to Xiao De Zhang. If he offends the Queen Mother, Xiao De Zhang will 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 Dezhang is probably used to it.
Moreover, Xiao Dezhang also suffered a lot at the beginning. After his father died, life at home was very difficult. 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 in your lifetime."
Unexpectedly, Xiao Dezhang, whose self-esteem was seriously wounded, went home and found out that working in the palace was a shortcut to making a fortune, so he gritted his teeth and committed suicide.
But it was not as if he could enter the palace immediately after he left the palace. He worked as a handyman for a banner family for three years. When a eunuch died in the palace, he filled the vacancy and entered the palace.
At first, he was assigned to a tea house. The master was an old eunuch who was known as "Haha Li" in the palace. He 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 De Zhang 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 eunuchs very harshly. After all, they were singing for the Queen Mother, so they did not dare to make any mistakes. These young eunuchs had become monks on the way, and their basic skills were not as good as those of famous Peking opera actors who had "graduated from a major", so the training was very strict.
Many young eunuchs were punished here with minor punishments ranging from being disabled to being disabled or even dying.
In fact, "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 to kill himself is really terrifying.
Within a few years, Xiao Dezhang was appreciated by Cixi, and soon he rose to prominence and became famous among the eunuchs.
Li Yu didn't want to ask too much about things in the palace. Anyway, he had heard that the 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 does father-in-law want from me?"
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 Dongjiao Min Lane, and they looked really nice. The Za family likes to draw and design houses when they are not doing anything.
, I just want to ask my husband to help me find some classics on this subject, is it okay?"
"Architectural design?" Li Yu asked in surprise.
Xiaode Zhang said: "It turns out to be this name."
Li Yu really didn't expect Xiaode Zhang to have such a hobby. He was a little surprised, but he had no reason to reject him, so he could only say: "I will buy some for you later."
Xiao Dezhang said, "Also, I heard that the paper and pen used by foreigners to draw are also different, or they should be used together..."
Li Yu also learned drawing geometry during his undergraduate degree in mechanical design. Although he didn't understand architectural design, he still knew how to draw.
"Okay, wrap it up on me."
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 was trying to get close to him, so he 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", 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, 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: "We should combine work and rest. You guys practice hard. When I come back from the United States, we will form a school football team."
Fan Xiren was so interested: "No problem! I will definitely take them to practice hard!"
After Ding Haoliang knew that Li Yu was 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, Mr. Liang Cheng is there for diplomacy."
Ding Liang said: "If it only involves education, the great American president will certainly not stand in the way."
Americans are very proud now, but there is nothing to say. They also have the capital to be proud.
"I hope so," Li Yu said, "although in the future..."
Ding Haoliang saw Li Yu pause and continued: "There will definitely be more schools rising in the future."
Li Yushun said: "Of course."
Li Yu took the time to sort out the chemistry lecture notes and sent them to Zhang Yuanji in Shanghai.
Within a few days, Liang Cheng found him.
Historically, it was indeed around this time that Liang Cheng left for the United States to serve as ambassador to the United States.
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. It passes through Japan and follows 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.
Physics and astronomy, the fields he is best at, have relatively good directions. Li Yu has 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 for him 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 to be brewed.
As a latecomer, Li Yu knew very well what the basis of quantum mechanics was.
——To put it simply, it is of course 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, or they can be infinitesimal.
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" in this world, which cannot be infinitely detailed.
Quantum mechanics also emphasizes that energy is "shared".
Anyway, no matter what it is, it is an integer multiple of the smallest unit.
In fact, as long as you mention "integer multiples" or "a portion by a portion", it will feel a bit like quantum mechanics.
But we are still in the "prehistoric stage" of quantum mechanics. Even though the great god Planck deduced the correct formula for blackbody radiation in "Two Dark Clouds" three years ago, it is a pity that he just made up the formula...
In other words, although the result is right, the process is wrong.
This is very uncomfortable! Because it is difficult to convince people.
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 very consistent with the experimental image. However, as mentioned above, the derivation process is wrong and everyone does not agree with it.
In addition, the German physicist Wien used thermodynamic theory 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 deduced a Rayleigh formula that was only consistent at low frequencies, but it was not perfect. And this theory was later used by many science fiction novels 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, but 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 and began to calculate.
He was so familiar with the process that 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 standard, and there are no errors.
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 you 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 another scientific paper."
Li Yu said: "Being idle is also idle, why not do something."
Liang Cheng asked: "Is it something incredible again?"
