Several more people raised their hands, and one of them was obviously Asian. Li Yu pointed to him: "This classmate."
"Hello, sir, my name is Hirayama Seiji, from Tokyo Imperial University, Japan."
It turned out to be a Japanese.
Li Yu's expertise included astronomy. He remembered that Hirayama Kiyoshi was specialized in asteroid research, that is, the asteroid belt between Mars and Jupiter. One of the tribes was the Hirayama tribe that he later discovered.
Unexpectedly, he is also in Paris now.
Hirayama Seiji continued: "I have always paid special attention to your husband's itinerary. I wanted to visit you when I was in London. But when I arrived in London, I learned that your husband had already left for Paris, so I quickly took a boat to Paris. I am glad to hear that you will be in Paris. I was giving a lecture at the University of Paris, so I came to the auditorium.”
Li Yu really didn't expect that he would still have Japanese fans, and they would chase him all the way. He was so persistent!
Hirayama Seiji asked: "I read Mr.'s paper on the discovery of Pluto, but I am more concerned about the 'exoplanetary belt' mentioned at the end of your paper. How difficult do you think it will be to discover this outer planetary belt?" "
Hirayama's ambition is not small, and his goal is to reach the outer reaches of the solar system.
Li Yu said directly: "I think it is very difficult to find it now, because the difficulty of finding small non-luminous celestial bodies is not low. The discovery of Pluto is already a coincidence to a certain extent. With the current observation conditions, it is difficult to find the orbit of Neptune." Objects in the outer solar system will be very difficult to detect."
It wasn't Li Yu who poured cold water on him, it was indeed too difficult.
If Li Yu had put it simply, with the stubborn character of the Japanese at this time, it is very likely that they would spend their entire lives looking for it, and the result would naturally be in vain.
Although Li Yu didn't have a good impression of Japan, he was not vulgar enough to deliberately disgust an astronomer.
Hirayama seemed a little unwilling to do so: "I think that if Pluto is discovered, we can naturally continue to search for the outer planet belt, because your article mentioned that they are not far apart."
"It's okay if you want to give it a try, but you'd better do your own research on the subject first. As for searching for exoplanetary belt rights, just treat it as a hobby in your spare time." Li Yu said this. If he returns to Japan, he will persist. There's nothing we can do about it.
It is a pity that Hirayama Kiyoshi did not do what Li Yu said. He stubbornly spent half his life observing space. In the end, he only stopped at the level of discovering asteroids and did not go any further.
There were so many students here today that we answered dozens of questions before the Q&A session ended. It had been a long time since he had spoken so many words, and Li Yu felt his throat began to hurt.
If it hadn't been for lunch, it seemed like they wouldn't let Li Yu go.
The principal came to the stage to give a concluding speech and invited Li Yu to write an article about the content of today's speech.
After the classmates dispersed, the Curies came to Li Yu. Mrs. Curie asked curiously: "You must be very tired, right?"
Li Yu was a smart man, and he knew what Madame Curie wanted to say from the way she glanced at the big braid behind her. After all, she had been looked at a lot strangely in the first half of her life.
Li Yu smiled and said, "I think I'm not tired yet."
Madame Curie smiled slightly. She was someone who had been there, so she naturally knew Li Yu's inner thoughts, but she did not delve into it deliberately: "That's all. If you need any help, the door of the Faculty of Science of the University of Paris will always be open for you. do you think so?"
Mrs. Curie’s last question was directed to her husband Pierre Curie who was standing next to her. As a professor at the School of Science, Pierre immediately said frankly: “I can write you a letter of recommendation at any time.”
"I sincerely thank the two professors for their kindness. I will take it to heart and will definitely remember it if I need it in the future!"
Li Yu was very moved. As a female scientist, Marie Curie was not only able to see the nature of science clearly, but her delicate cognition also allowed her to see the nature of human nature clearly. The level was indeed as high as what was written in the book.
Li Yu thought for a while and said: "Madam, you must pay attention to the dangers of radioactivity in the future. There is a Chinese saying that water can carry a boat or capsize it. Radioactivity is of course very important to the scientific development of mankind, but it itself has extremely harmful effects on the body. Big harm.”
Madame Curie said calmly: "I know."
Madam Curie's attitude shocked Li Yu, and he didn't know what to say for a moment.
Suddenly it dawned on me and I was in awe: Yes, she is an expert on radioactivity, how could she not know!
Madame Curie continued: "If you can, I hope you can write down the Chinese proverb you just said for me. Just write it in Chinese. I like square characters very much."
Li Yu just said it in English, so he replied: "Of course."
Culture belongs to the world, and now many foreigners like Chinese calligraphy and culture. It's a pity that Li Yu could only barely write with a pen. His hard-pen calligraphy was okay, but when it comes to strictly speaking about the level of calligraphy, it can only be said that he only has the style and the artistic conception is completely inadequate.
Fortunately, Marie Curie liked it very much after reading it: "I will keep this valuable paper well. I once heard that it was also a saying that Li Shimin, the emperor of your country's Tang Dynasty, liked."
Li Yu said: "Yes, and these eight characters actually originated from the writings of Xunzi, a Chinese thinker more than 2,000 years ago."
Marie Curie sincerely praised: "It is such a far-reaching culture. If I have the opportunity, I will go to China."
Li Yu said with a smile: "Then I have to send you a few more words: It is a joy to have friends from far away." After Li Yu finished writing, he handed it to her and explained the meaning in English, "This is what Confucius said of."
Historically, Marie Curie did want to come to China. When Mr. Cai Yuanpei came to France in 1921, he invited her to give a lecture at Peking University in the future. Marie Curie readily agreed, but unfortunately she was unable to make the trip.
Madame Curie looked at the two pieces of manuscript paper in her hand: "You forgot to sign your name."
This was the first time for Li Yu to sign for someone, and the other party was still a big shot of this level, but it was obvious that Madame Curie was just asking for it out of politeness, and it gave people a very comfortable feeling.
In the end, Li Yu did not forget to say to Pierre Curie: "Professor, if you can, please pay attention to traffic safety in the future!"
Pierre was very puzzled by this nonsense: "Traffic safety? You mean the new cars on the road?"
In fact, the car accident in which Pierre died four years later was not caused by a car, but by a horse-drawn carriage. Of course, a horse-drawn carriage is also considered a car accident.
Li Yu said seriously: "In short, you must pay attention to traffic safety!"
Seeing how serious he was suddenly, Pierre thought he was caring about him, and wondered if he also knew that he wanted to go racing with Perrin? So he replied with some emotion: "I will definitely pay attention!"
After settling this matter, Li Yucai met with Yugeng's family and Huang Kaijia and prepared to return to the embassy. They were surprised by Li Yu's performance just now. Although they didn't understand anything, it must be extraordinary that even the president of the University of Paris attended in person. You must know that the status of the president of the university was quite high back then.
They had been applauding vigorously just now, and the crowd was full.
Yu Rongling has completely become Li Yu's little fan girl: "Brother Li Yu, you are so great! Although I don't understand anything!"
Yu Deling smiled and said: "Then you are so confident in what you said. Study more in the future and don't fall asleep as soon as you see the book!"
Yu Rongling made a face at her sister, not convinced at all.
Minister Yu Geng raised his hand and said: "I have been on missions to various countries for seven years. This is the first time I have encountered a talent like you. I admire you!"
It is true that they did not understand advanced science, so Li Yu casually replied: "It's a fluke."
There was no car to ride back to the embassy, so we had to take a carriage back.
During the day, Zai Zhen took the special envoy to watch the military parade. The new equipment of the Western army was quite shocking to him.
Nowadays, the French army is really not weak, and the army is eager to have another fight with Germany next to it.
However, the casualties in France during World War I were really unacceptably heavy, with more than 10% of the population lost, and most of them were young adults. So after that, I was completely discouraged. In later generations, many people will even use the fact that they only resisted for more than 40 days during World War II as a daily insult to the law.
The evening activity was arranged by Yu Geng to go to the Paris Opera House to enjoy an opera. Zai Zhen watched the military parade for a day and was deeply shocked. He also wanted to listen to an opera to relieve his stress.
At this time, French opera was second to none in Europe, competing with Italy and Germany.
Zai Zhen sat in the theater with the envoy. He usually liked to listen to plays, but he didn't know what plays Westerners listened to, so he happened to want to watch it.
Anyway, the special mission just wanted to inspect all aspects along the way, so it was also a matter of how Westerners usually entertain themselves.
The first "side dish" performed was a few dances, including Yu Rongling. However, they did not perform ballet today because they were really afraid of scaring those old feudalists with their attire.
Western modern dance is something Zai Zhen and others have never seen before. It is completely different from Chinese dance and is unrestrained and passionate. Roong Ling and other members of the dance troupe also danced gracefully, which helped build momentum for the subsequent opera.
After the dance, the next feast was the famous opera "Carmen" created by French composer Carby.
In later generations, "Carmen" has become the most frequently performed opera in the world. Regardless of whether you have seen the opera or not, you must have heard at least its overture "The Song of the Matador" and the aria "Love is Like a Free Bird" by the protagonist Carmen.
Zai Zhen had never seen this kind of performance before. The passionate overture "Song of the Matador" at the beginning immediately filled the atmosphere, and then hundreds of people took turns performing on the huge stage, just like watching a movie.
It's a pity that Zai Zhen and the others don't understand French, so they only relied on translation to get a general outline of the plot.
The plot of "Carmen" is actually not complicated. It just tells the story of a gypsy girl named Carmen: she first seduces an officer and makes him abandon his existing lover; then she falls in love with a bullfighter, but eventually dies after the officer subordinates.
On the one hand, Carmen is bohemian and has almost no moral bottom line, but on the other hand, she advocates freedom and would rather die for it. This kind of two extremes appearing in one person at the same time is a very common artistic expression technique in the West, which is to greatly increase the tension.
But for Zai Zhen and the others, it was a bit difficult to understand.
After watching the nearly three-hour opera, they were truly shocked and inspired. Anyway, after a trip to the West, Zai Zhen's three views were almost shattered.
When Zai Zhen left, he shook his head and commented: "The singing is good, the music is also good, but the woman in the role is not good!"
