When Li Yu was in Copenhagen, Denmark, he was also invited to the Copenhagen Observatory. After all, the discovery of Pluto and the recent articles on exo galaxies, red shift phenomena, and the spiral arm structure of the Milky Way published in the "SCE" magazine are all incredible achievements in the field of astronomy.
The reputation of the Copenhagen Observatory is obviously not comparable to that of several other observatories in Europe, but Denmark's research on astronomy is actually very traditional.
The famous Tycho Brahe began large-scale astronomical observations more than 300 years ago, and his data directly helped Kepler complete the brilliant Kepler's three laws.
More than 200 years ago, Ole Romer, who was the first to measure the speed of light more accurately, was also from the University of Copenhagen. After years of development, the measurement of the speed of light was crucial to the creation of the theory of relativity.
At this time, the director of the observatory was an astronomer named Hans. When he saw Li Yu, he said in Chinese: "Hello, Mr. Li Yu!" Li Yu was stunned for a moment before replying in Chinese: "You Good!" Principal Paterson said with a smile: "Director Hans is a 'China expert'. He can not only speak but also write Chinese!" For foreigners who learn Chinese, writing Chinese is more difficult than speaking it. Like a nightmare, it is really not easy for a foreigner to write Chinese.
Hans was also very proud of this: "I also compiled a Chinese code about your country. There were so many square characters that I felt like my head was going to explode when I was compiling it." Almost 30 years ago in 1873, the world's first With the Chinese code, the reference was the "Kangxi Dictionary", which used nearly 7,000 Chinese characters.
Zheng Guanying, whom Li Yu once met in Guangzhou, integrated them into a "New Edition of Chinese Telegraphs".
Later, Wang Chengrong, the overseas Chinese businessman who was the first to develop a telegraph machine in China, co-developed China's first telegraph machine and petitioned the Qing court to develop its own telegraph machine, but the Qing court directly refused.
Because the Qing court felt that foreign products were better. However, the court's code was entirely made by foreigners. It was very difficult to encrypt it, but it was not difficult for others to decipher it.
This is a huge loophole. Today, most of Shanghai's cross-sea telegraph lines are constructed by the Danish Great Northern Telegraph Company.
They also signed a contract with the Qing government, obtained privileges such as borrowing routes and patents for sending and receiving newspapers, and operated the business of sending and receiving newspapers.
The key point is that the Qing government really didn't understand communications and completely handed over its core business to the great powers. Hans was the Chinese code produced for the Great Northern Telegraph Company in Denmark.
Paterson said: "If academicians need to communicate with China, they can directly send telegrams in Chinese in Denmark." It seems that they do not know that Li Yu has mastered radio technology.
So Li Yu said casually: "It's not needed for the time being." Hans pointed to his observatory and said: "During this period, I have been using Academician Li Yu's method to observe and search for Pluto and extragalactic galaxies. It's a pity that the equipment of my small observatory cannot reach it. To achieve such a high accuracy, I just submitted an application to the Academy of Sciences for updating." Li Yu said: "If the funds can be approved, it will be very convenient to upgrade the telescope." Hans smiled: "I also submitted your paper at that time I submitted it together with the application form. I think they saw your article and realized that there is such a vast field of astronomy that has yet to be discovered, so they approved my application. Academician, your contribution is not small!" Li Yu felt five emotions in his heart. Za Chen, if he wants to buy some equipment, he can only pay for it himself.
Key observatories are really expensive. Hans continued to say excitedly: "After the equipment is updated in the future, we may be able to use it to make greater discoveries." Li Yu said: "The equipment is good on the one hand, but people are also needed to bring out the value of the equipment." Paterson The principal said: "So we really hope to invite you to come more often." Li Yu could only say: "I will if I have the chance." They wanted to keep Li Yu for a while now, but Berlin, Germany, sent another urging telegram. .
The senders were Siemens and the University of Berlin. They had long known that Li Yu had arrived in Denmark, but they had stayed in Denmark for a few days and had not yet left for the south, so they sent an inquiry.
Li Yu unfolded the message: "Dear Mr. Li Yu, with all due respect, we have already vacated a laboratory and have contacted Professor Planck of the University of Berlin. Everything is waiting for your arrival. - Carl Siemens." Li Yu Yu smiled and said, "It seems I'm really going to leave." Everyone at the University of Copenhagen knew that Li Yu came to Europe this time for an appointment in Germany, but there was still time to invite him in the future.
Paterson said: "After Mr. Academician completes his work, he can come to Denmark at any time." Denmark and Germany are neighboring countries and are indeed very close.
But Denmark is not alone in thinking this way. Li Yu had no choice but to prevaricate for a few words, then packed his luggage and continued to set off.
Li Yu boarded the ship from the port of Copenhagen and went to the nearest port of Kiel, Germany. Then he took the train all the way south, turned southeast via Hamburg, and headed to Berlin Railway Station.
In the following decades, Germany has been very strong in science, even affecting all aspects of Germany.
It’s hard to imagine the Germans’ enthusiasm for technology. Even during World War II, when the war with the Soviet Union reached the level of national destruction, the home front was still researching hundreds of new weapons and equipment at the same time.
The routes of Germany and the Soviet Union are obviously different. Germany really uses technology as a magic weapon to win. It is indeed very pioneering in many fields, and it has begun to develop rockets.
The Soviet Union's line is mainly about being easy to use and durable, and the models are relatively single. For wartime, this actually makes logistics easier to operate.
This also affected the manufacturing principles of Soviet-made weapons to a certain extent, and also led to the large-scale popularity of AK in the world.
The journey was boring anyway, so Li Yu chatted with Lu Bicheng about the history of Germany, especially Bismarck's great contribution to Germany.
In terms of culture and history, Lu Bicheng can still understand quickly, but those parts involving modern science are too difficult for her.
Germany rose relatively late among the European powers. It has almost no colonies. The road to becoming a powerful country started in a difficult mode. Several large-scale foreign wars were almost all about snatching food from the tiger's mouth.
After that, the development of industry was also very brilliant, and in a few decades it became the strongest country in continental Europe.
However, Lu Bicheng was more interested in literature and art, and was not very interested in history such as fighting and killing.
Li Yu thought for a while and said, "As for literature... By the way, Germany also has very famous fairy tales."
"Like the Danish Andersen fairy tale?" Lu Bicheng asked. Li Yu said: "Naturally, the Germans' Grimm's fairy tales are not weaker than Andersen's fairy tales." Like Andersen's fairy tales, Grimm's fairy tales have not entered China now.
Li Yu then told her about famous works such as "Cinderella", "Snow White", "Little Red Riding Hood" and "Sleeping Beauty" which have long been popular in later generations.
Compared with the previous Andersen fairy tales, the Grimm fairy tales are more romantic, and are naturally more popular among girls.
Many of Andersen's fairy tales are more moral and have certain connotations, such as the very typical
"The Emperor's New Clothes", in fact, children don't understand why everyone tells lies with their eyes open.
Of course, both are classic fairy tale collections, and there is no distinction between them as good or bad. It's just that the different times in which the authors lived have certain differences in the stories.
Lu Bicheng indeed prefers Grimm's fairy tales. After all, China is currently being bullied by foreign powers, and the domestic mood is generally not optimistic and relatively depressed. Such a beautiful story can give people some room for good imagination.
For Chinese people in the early 20th century, Grimm's fairy tales were more like a dream
"Fairy tale world". ——It’s a pity that we can’t live in dreams all the time. Lu Bicheng said: "I want to bring these stories back to the country!" Li Yu encouraged: "Of course you can, the translation of fairy tales is not difficult anyway. If you go to France and see those big masterpieces, I guess you will be less motivated to translate. No." After telling a fairy tale in a country that respects technology, they finally arrived at the Berlin train station.
Kohlrausch, director of the Imperial Institute of Physics and Technology, brought Kurban and Rubens from the laboratory to greet Li Yu.
Li Yu could immediately feel the Germans' obsession with technology: Kohlrausch and others drove a fashionable new Mercedes-Benz car to greet Li Yu.
After a few words of introduction, Kohlrausch took off his hat and said: "Mr. Li Yu, I'm sorry that only a few of us are here to greet you. We really can't make up so many cars of the same model, but Mr. Siemens and Mr. Planck are both at the headquarters." Waiting for you." If Planck came to pick him up, Li Yu really felt that he couldn't afford it, so he smiled and said: "It doesn't matter, I just want to drive a car." Kohlrausch was surprised: "You can also drive. Car?" Li Yu said: "Not only can I drive it, I am also researching car patents!" Kohlrausch had not heard about Li Yu's patent in the United States. After all, it had not been mass-produced yet, so he asked: "Car Patent?!" Li Yu said: "Yes, including electronic starting systems, four-wheel drive systems, electric lights, etc." When Kohlrausch heard these professional terms, he knew that Li Yu was not bragging, and his eyes almost widened. He came out, but still couldn't believe it, and asked again: "Is this true?" Li Yu spread his hands: "Why are you lying to me? If you don't believe me, you can go to the US Patent Office to check the patent documents."
"Oh my God!" Kohlrausch exclaimed,
"It really surprises me. Your brain is a hundred times bigger than mine! You can actually have such advanced patents in the automotive field! What gives me the most headache right now is the way the joystick is activated. It's really weird. Gentleman, sometimes engine oil will spray on your hands or even clothes." Li Yu said: "Your ideas from real users are the driving force for me to improve the car." Kohlrausch said excitedly: "I will make it after get off work today. Go tell Mr. Benz and Mr. Daimler, they will be very interested!" These two people are naturally the founders of Mercedes-Benz.
Li Yu sat in the driver's seat and said to Lu Bicheng: "Get in the car." Lu Bicheng looked at the thing in front of him in surprise: "This is it?" Li Yu said: "A car is a tool that can walk." Lu Bicheng said: "A train? I've seen it before, this one is too small!" Li Yu said with a smile: "You can use it as a mechanical carriage, it has the power to move forward without the need for additional horses." Lu Bicheng clicked his tongue She was amazed: "It's unbelievable!" Li Yu stretched out his hand to help her up.
"There will be them in China in the future, and you won't think it's strange if you see them more often." Lu Bicheng touched the iron bump and continued to ask: "Can such a small car really drive by itself?" Li Yuxin said in front of the girl Showing off, he said proudly: "You will know when you run, you can sit still!" Then he skillfully put the gear into gear and accelerator and drove off.
"Ah!" Lu Bicheng exclaimed,
"It's so amazing that you can really run!" Li Yu said with a smile: "Of course! You can turn wherever you want, watch it!" Turning a big bend, Lu Bicheng suddenly leaned on Li Yu's shoulder; then Li Yu continued Throwing the car body over again, Lu Bicheng immediately threw it to the other side.
Although it only has a speed of 20 to 30 kilometers per hour, for people who see a car for the first time, it is simply a surprise.
Li Yu said happily: "It's interesting!" Lu Bicheng smoothed his messy hair: "It's indeed interesting. There are such interesting things in the West. But how can you control an inanimate machine so skillfully?" Li Yu was a little confused He said proudly: "It has life, and its life is my life. The car is the love of a man's life!" Lu Bicheng looked at Li Yu's expression and whispered: "The love of his life?" She put
"Beloved" is heard
"Beloved", just one word difference, has a big difference in the delicate psychology of women. She can't understand what kind of complex it is.
Li Yu said: "What did you just say? The engine was too loud and I didn't hear clearly." Lu Bicheng quickly said: "No...it's nothing!" Li Yu had already driven a kilometer or two and suddenly realized that he didn't know the road. !
Although I had spent some time in Germany as an exchange student before traveling, I was mostly in Munich. Now I am on the streets of Berlin a hundred years ago.
Li Yu suddenly felt his eyes darken, but fortunately, Kohlrausch caught up with him in a car a few minutes later.
"Mr. Li Yu!" Kohlrausch said,
"Your driving skills also surprise me. It seems that I can introduce you to Mr. Porsche to participate in racing competitions." Li Yu said with a smile: "Then you have to convey it properly." Kohlrausch said: "You Can you slow down a little? I'm not very good at controlling gears." Li Yu said: "Of course, you have to lead the way." Kohlrausch breathed a sigh of relief, but unexpectedly Chinese people are so wild. The first thing they do when arriving in a strange city is to take a girl and race on the streets of Berlin!
Fortunately, Li Yu followed him honestly in his car. Lu Bicheng is still very interested in this car: "Can such a robot carriage appear in Beijing or Tianjin in the future?" Li Yu said: "Definitely, why do you ask?" Lu Bicheng said: "I also want to learn to drive such a machine in the future horse."
"Um, its name is a car," Li Yu said the name again, and then asked,
"Why do you want to drive a car?" Lu Bicheng said seriously: "Because you said this is the love of a man's life. I can do everything a man can do, and... looking at driving a robot horse, oh, driving a car is still... It's pretty cool." Li Yu said with a smile: "So that's what happened, it's easy to say, I'll give you one as a gift." Lu Bicheng blushed: "I didn't tell you to give it to me, I will spend money to buy it myself." Li Yu drove Che was in a good mood, and he could supply products to Che. A car was no big deal, so he said nonchalantly: "It's just a car between the two of us. There's nothing to be polite about!" Lu Bicheng said lightly: " Why are you talking about 'who is following whom' again? I... I said I would buy it myself, so I will buy it myself!"
"Okay, okay, just do as you say!" Li Yu said with a smile,
"But in my opinion, riding a horse is much more chic than driving a car." Li Yu didn't lie. In his previous life, not many people had the opportunity to ride a horse.
Today's Berlin is certainly not as large as later generations, and it didn't take long for them to arrive at Siemens.
Li Yu no longer smiled playfully with Lu Bicheng, and his expression immediately became serious, because the great god Planck, the founder of quantum mechanics, had appeared in front of him.
His image was so famous that Li Yu recognized him at a glance. But... it's really a bit sloppy... Planck's famous unkempt photo was taken around the beginning of the 20th century.
Li Yu couldn't help but sigh: "It's so similar!"
