Snowflakes are already falling in Switzerland, and the train from east to west just passes by the foot of the Alps. The scenery is still good.
Switzerland is a country with very few plains, only five or six percent, and the rest are mountainous. This is one of the reasons why Switzerland was able to survive World War II. After all, no one believed that the status of a neutral country was really useful.
Belgium was also a neutral country during World War I and World War II, so it could be attacked without fail.
Moreover, even during World War II, Switzerland was not completely neutral. The financial system had always helped Germany, and some of the domestic road tunnels were also used by Germany.
On the train, Li Yu looked at the Xuande furnace in front of him. He was sure it was genuine, because the royal family could not collect fakes.
The condition is also very good. In future generations, it will definitely be the kind to be sold for a million dollars.
Xuande furnaces are so famous that many imitations were produced during the late Qing Dynasty and the Republic of China. The imitations were so good that it was difficult to tell whether they were genuine or not.
Li Yu said: "The ancients said that red sleeves add fragrance and study at night. It turns out that this is what it is."
"Don't be ashamed, who do you want to add fragrance?" Lu Bicheng said, "And are you willing to use such a good stove?"
"I definitely can't bear to part with it," Li Yu put it away carefully and sighed, "Hey, sometimes things are too good and it's a kind of distress, just like a vase, I don't dare to use it easily."
——
Einstein was at work, to be precise, he was fishing while working. Now his brain was almost exhausted, with several papers crowded in front of him.
Thinking about physics is already extremely taxing on the brain, as well as the mountain of mathematics.
Pure physics is not that difficult, the main thing is to have very advanced physical thinking.
What really makes physics difficult is mathematics.
Anyone who has taken the college entrance examination will realize that force analysis of big physics questions can often be done, but complicated mathematical calculations can really stump you.
(You can experience the difficulty of the Shandong Physics paper, which is so many calculations that your scalp is numb.)
The staff of the Patent Office received Li Yu. Li Yu directly asked to see Einstein by name. The receptionist asked Li Yu to wait here.
After a while, Einstein hurriedly walked out with his trademark chicken coop on his head. The circles under his eyes were a little dark, and he seemed to have not slept well.
"Oh! It turns out to be Mr. Li Yu. I didn't expect you to come to Switzerland again. What's the purpose of your visit this time?" Einstein asked.
Li Yu pointed to a pile of documents in his hand: "Of course there is business."
Einstein hurriedly asked: "Is it Minkowski space or Lorentz transformation, or is it the Navier-Stokes equation that discusses fluids?"
It can be seen that his mind is currently occupied with studying his thesis, and all he talks about is complicated mathematics.
Li Yu smiled and said, "None of that! I want to talk to you about the work here."
"oh……"
This "Oh" was obviously not as exciting as the previous one, but Einstein immediately remembered that he was still at work, which was not good, and hurriedly said: "Are you going to apply for a patent?"
"Of course, I am here specifically to support your work." Li Yu said still smiling.
"No problem," Einstein pointed in. "Please come to my desk."
Einstein sat at his desk and looked through Li Yu's patent documents. The first one attracted him: "What is this? Car...horn?!"
Li Yu nodded: "And it's an electric horn."
In 1899, France was the first to enact regulations requiring cars to be equipped with sirens. But early horns were not controlled by current, but made sound by air flowing through pipes, just like traditional wind instruments.
Basically, a soft air bag is connected to a curved pipe, and the air bag is squeezed by hand to make the air flow quickly through the pipe and produce a resonance sound. The sound is then amplified through the amplification design at the end. The principle is basically the same as that of musical instruments such as French horns.
I remember that there was an episode in "Tom and Jerry" - probably the most tragic episode - called "Sad Cat". It was about Tom falling in love with a beautiful white cat, and his good friend Jerry tried his best to stop him because He knows that there is a super rich black cat who also pursues the beautiful white cat.
When Tom brought out a flower, the black cat gave a large bouquet; Tom gave the white cat a small bottle of perfume, and the black cat came with a truckload of perfume; Tom bought a pocket diamond ring, but the black cat gave an oversized diamond ring. .
Finally, Tom bought a second-hand car with 312 monthly installments and an annual interest of 112%. This car was the first car invented by Carl Benz. When Tom drove the shabby car to the white cat, , and even pinched the airflow principle horn.
Well, then Black Cat drove a stretched luxury car and ran over him.
Love really breaks the heart of a cat...
This kind of horn is definitely not very easy to use. Early cars were cumbersome to operate, and the steering wheel had no power assist, making it difficult to control the direction. It also had to free up your hands to squeeze the horn, which was very unsafe.
Einstein could see at a glance that Li Yu's electric horn was an excellent plan, and said happily: "Oh my God, it's a genius design! We just reviewed and approved a plan yesterday. Although it is a bit better than the air bag horn, it is not as good as Get rid of airflow restrictions.”
Einstein rummaged through his messy desk and took out another patent document for a car horn, which was about making sound through the airflow blown out by the car's exhaust. Divide the car exhaust pipe into two pipes, and design a manual valve in the middle of one of the pipes. When the valve is opened, exhaust gas will flow through the horn's pipe and make a sound.
This solution not only adds a long pipeline, but also blows out exhaust gas, so it is not very popular.
After the emergence of electric speakers, it can be called a dimensionality reduction blow. The two are not opponents of the same level at all. Electrically driven speakers use metal vibrators to drive the diaphragm to emit sound. Both the sound loudness and the response speed of the speaker are greatly improved compared to traditional pneumatic speakers.
Li Yu smiled and said: "I still have a few patents, and I hope I can use them to make you an official patent office employee."
The patent office where Einstein worked also had KPI indicators. Only those who completed well could be promoted.
Li Yu once again laid out several patent documents, including new mechanical transmission structures and better shifting components.
In addition, Li Yu also took over some patents applied for in the United States, such as seat belts.
These things all belong to mechanics, and the structure, especially the mechanical structure of the seat belt, is very clever.
It looks like just a simple strap on the outside, but the mechanical structure of the seat belt is really unique. The clever locking structures work together, making it very much like a beautiful piece of industrial art, and it is even more worthy of the "safety" in its name. "Two words.
Unlike the United States, European racing culture was more prevalent at this time and they were more interested in seat belts.
Einstein immediately sat down and reviewed them one by one.
Li Yu was sitting next to him at leisure. He saw the calculation paper hidden in the corner of the table. It was filled with dense derivation and calculations. It was obviously not the work of the patent office.
Since Li Yu was far ahead of the times in terms of mechanics, the drawings he drew were extremely clear and reliable, and the physical and mechanical principles he used were accurate. Einstein quickly stamped his blue stamp and took it to the director. Final Judgment.
When he saw Li Yu's name on the patent application, the director had almost made a judgment, but he still followed the procedures and conducted a thorough review.
Not long after, it was signed and sealed.
Einstein was so happy that he came to Li Yu with the documents: "It's all passed! But the specific use still requires us to conduct a batch of trial production."
Li Yu didn't expect that Switzerland's efficiency was so much faster than that of the United States. Most likely, they wanted to leave such good patent documents. Even if there were some problems, they could continue to let Li Yu improve.
Li Yu said: "That's great, I thought I had to wait two more days."
"To be honest, if the verification is successful, I can be promoted to a full-time employee immediately." Einstein couldn't hide his joy.
The income of a formal third-level clerk can increase to more than 1,000 US dollars. At this time, the annual salary of a professor's assistant is only 400 to 500 US dollars.
This was out-and-out good news for Einstein, "Dear Mr. Li Yu, you are simply my lucky star! If Mileva knew about it, she would be very happy! With money, we can buy more Good furniture, even for a holiday.”
"Don't be too eager to be happy," Li Yu said with a smile, "This time I came, I was still thinking about the paper on perfecting the special theory of relativity with you."
"Narrow sense?!" Einstein slapped his head, "It's a great word, but it already makes my brain almost explode."
Li Yu naturally knew that it was mathematics rather than physics that troubled him, "So I took the initiative to ask Ying to help you and be a little assistant."
Einstein said: "I will regret having you as my assistant."
"You're welcome," Li Yu waved his hand, "When you're done, just treat me to a skiing vacation."
Einstein brought Li Yu to his home. This was Li Yu's second time here. As soon as he walked in and greeted Mileva, he was dragged to the study on the second floor by Einstein.
Only Lu Bicheng and Konoe Aoyuki were left standing in the living room.
Mileva saw that there was one more beautiful girl than last time. She was a little overwhelmed and did not dare to ask any more questions. She just said: "Ladies, please sit down and I will make you coffee."
Einstein is not very famous now, otherwise Konoe Akiyuki, as an intelligence officer, would definitely pay more attention to Einstein's achievements, although he may not be able to understand them.
The physical part of the theory of relativity was basically completed by Einstein independently, but for its mathematical proof, he asked many people for help.
Although Li Yu is not as good as professional mathematicians in mathematics, he still understands the mathematics of physics relatively well. This is a necessary skill for future generations of physics majors.
It only took Li Yu seven or eight hours to completely perfect it.
Einstein was very excited: "This has reached the level of publication. Today is really the happiest day I have spent this year!"
It was already early in the morning, and Li Yu and Einstein ate a piece of bread that Mileva left on the table. "Can I go skiing tomorrow?"
"It must, it must be possible!" Einstein said excitedly.
