At the party that night, Rongling also performed a beautiful modern dance for everyone. If the person in the Qing Dynasty who is best at modern dance is probably Rongling.
The next day, Li Yu asked Pu Lande to arrange for someone to set up a telegraph line.
One of the supervisors was very conscientious and even sometimes set up the lines himself.
However, the reason why he attracted Li Yu's attention was mainly because he was the only Chinese among several British Telegraph Office workers, and he seemed to have quite high professional abilities.
Li Yu asked curiously: "May I ask your surname?"
The man said: "I am Jiang Shixuan. I have always heard of Mr. Li Yu's name, but I have no way of visiting him. I didn't expect that I could personally set up a telegraph line for you today."
Jiang Shixuan was also a strange person. He once served as the censor of the Guangdong Supervisory Road, and twice impeached Yikuang. However, Prince Qing's position in the court was already stable, so Jiang Shixuan failed to impeach him and was dismissed from office.
Moreover, the imperial court issued a decree to warn Jiang Shixuan. A eunuch named Wang in the palace cursed Jiang Shixuan with a slap in the face in front of everyone:
"There is an imperial decree issued to Jiang Shixuan, kneel down and listen to it! Jiang Shixuan, you bastard bastard, you don't know how to appreciate others, and you have caused a lot of trouble. You surnamed Jiang are not good people, but Jiang Shixuan is even worse, get out!"
Jiang Shixuan was scolded on the spot and became disgraced.
It was a system of the Qing court to give orders to officials, and it was a good job for eunuchs. In fact, if the money is given in advance, the eunuch will not be too abusive. However, it was Prince Qing who Jiang Shixuan offended, and the eunuch did not dare to accept his money.
But Yi Kuang is also really interesting. He rarely kills his opponents completely and just makes him lose his hat.
After Jiang Shixuan was dismissed from office, he did not lose heart and even started new industries.
At this moment, he pointed to Li Yu's house and said, "It seems that there are no electric lights in Mr.'s house."
Li Yu said: "Of course, telegraph lines can still be installed, but I can't install a generator at home."
Jiang Shixuan sighed: "If nothing else happens, I will soon provide lighting lamps to the people of the capital."
Nowadays, except for Xiyuan and Dongjiaomin Alley, Beijing has no power supply at all, let alone electric lights. When the night falls, it is completely dark, and there is no night view.
Xiyuan uses its own generator set. The electricity used in the embassy district comes from German electrical companies, which are now greedily coveting the vacant electric lighting market in the capital.
Anyway, in their eyes, everything in Qing Dynasty is a piece of fat that can be taken a bite.
Li Yu said: "Do you want to create an electric lighting company?"
Jiang Shixuan nodded: "It is quite difficult to promote the telegraph market now. There are too few people who can afford a telegraph machine or can use a telegraph machine, but the electric light market is still huge."
Li Yu felt that Jiang Shixuan was interesting, so he said, "I also think that it is urgent to build an electric lighting company. After you debug the telegraph machine, we can study it in detail."
It is rare to meet a person who is passionate about Western science and technology. Jiang Shixuan said happily: "It is said that Mr. Li has profound attainments in Western learning. If I can have your help, it will be of great benefit to me."
Li Yu said: "I will try my best to help if I can. It is a good thing to have electric lights. You can make money and the people can enjoy happiness. Okay, I see that you have almost set up the telegraph machine. I will go in and try the telegraph machine."
Telegraph lines are now installed in the air. Zhao Qian often runs around Beijing and recognizes these telegraph poles. He said: "My master is really foreign. I have seen a lot of these things in Dongjiaomin Lane."
Fengling smiled and said, "Isn't the master going to open an embassy in the courtyard to meet foreigners?"
Uncle Wang said thoughtfully: "Don't tell me, I think it's really possible for our master to do it!"
The telegraph lines in Beijing at this time were really messy. There was no urban management to manage them anyway, so messy lines could often be seen. Moreover, if you set up a telegraph, people might think that you are related to foreigners or central officials, and they would not dare to interfere at all.
While the installation was in full swing, Ronglu's son Balon came over and said angrily: "Can this piece of shit stop walking in front of our house?"
Fengling was not angry when she saw Ronglu's son, "If you put up wires on the road, it won't bother anyone!"
Balon frowned: "It's these foreigners who ruined my feng shui!"
Li Yu, who was in the room, heard the noise outside and came out and said, "It turns out to be Mr. Balong, disrespectful and disrespectful."
Although Balon knew that Li Yu was indeed very good in science, he was also very traditional and looked down on Western learning at all. He said dissatisfiedly: "The foreigners' telegraph lines have interfered with our Rongfu."
Li Yu looked at the telegraph poles. They were high enough, so he said, "They only serve the telegraph machine in my home. How can they affect your house?"
Baron said: "Of course it has an impact. The foreign copper wires are thousands of miles away and can be connected in an instant. Although we don't know the reason, we have been spreading rumors and incidents in various news for so many years, and we have no way of knowing. What's more, If the copper wire passes through my Rong Mansion, wouldn't the confidential information in my house be eavesdropped as well."
Li Yu said: "How could the secrets of your residence be known by a mere telegraph line on the road? How can you be so clever? You are worrying too much."
Baron didn't believe it at all: "How do I know what you said is true or false?"
Li Yu smiled and said, "You can ask any foreigner. They probably also want to know how to know the surrounding information simply by using copper wire."
Balon didn't understand at all and couldn't argue with anything, but he was still very angry and wanted to file a complaint when his father came back.
Li Yu sent Baron away and continued to write in his study. He made rapid progress and had already written about the "butterfly effect", which is very critical and the most famous in chaos theory.
The "butterfly effect" originally came from a speech by Lorenz, but he originally said that "a seagull flapping its wings is enough to change the direction of the weather."
He originally used "seagull". As for the origin of butterfly, a reporter actually saw that a graphic about the "Lorentz attractor" in the paper looked very similar to a butterfly, so he wrote it as "butterfly effect".
But in fact, China has always had similar sayings, such as: A dike of a thousand miles is destroyed by an ant nest;
All reveal the most critical point of chaos theory: extremely small perturbations to the initial value will bring huge and unpredictable changes to the system.
Li Yu proposed this point of view sixty years in advance, but called it the "ant nest effect."
Later, in order to commemorate Li Yu, many people directly called it the "carp effect".
This term was coined by Shi Liangcai, a reporter from Shenbao. He changed the expression based on the homophony of Li Yu’s name and the views he expounded: The ripples caused by a carp swimming in the Yellow River are very likely to cause a ripple in the Pacific Ocean. An invincible hurricane.
It's a reasonable explanation.
Sixty years later, when Lorenz used a computer to simulate the butterfly-shaped Lorentz operator, the two together became synonymous with chaos theory.
Of course, Li Yu did not stop there. His mathematical skills were sufficient, and he further used differential geometry to explore the mathematical principles of chaos theory. Regarding the description of this chaos, content including probability theory and mathematical statistics is used.
This paper took much longer than his previous paper on X-rays and the second law of thermodynamics, taking a full month to complete.
Of course, this is just the beginning of chaos theory. As for the follow-up, it still needs further development by other mathematicians.
However, it is not easy to achieve this level. After all, it has created a new and extremely important category of mathematics.
If we continue to write in depth, chaos theory may not be completed for another year. Li Yu knows when enough is enough and the core points should be clearly stated. Then he sent the paper after checking it.
The paper is quite thick, more than two hundred pages, almost the size of a mathematics book.
Li Yu also received 2,500 kronor from Sweden on the same day. The telecommunications system in this era was not as developed as in later generations, and it was inter-bank and multinational. Therefore, HSBC received the remittance today, and as usual, it still deducted about 10% of the formalities. fee.
But after all, there were more than 300 taels of silver.
