Open an aircraft carrier to fight against Japan

Hilbert walked so fast that he disappeared at the door before Lin Yuan and Zhang Yuanyi could react. Lin Yuan asked in surprise: "What's going on? Didn't you mean this Will Riemann's conjecture be able to conquer him?"

Zhang Yuanyi was also full of confusion, and said: "Yes, according to the history I have read, Hilbert has done a lot of research work on Riemann's conjecture, and what I wrote is the latest proof of Riemann's conjecture. I would be interested, but why did he just leave! Is there something wrong with the history books?"

Lin Yuan took Zhang Yuanyi's paper full of formulas and said suddenly, "I understand what's going on!"

Zhang Yuanyi hurriedly asked: "What's going on? Is there something wrong with what I wrote?"

Lin Yuan said: "Symbols, the key lies in the symbols! Compared with our era, the mathematical symbols of this era must have changed. He must not be able to understand what you write with the current symbols, so he thought we were doing it. I was playing with him, so I left."

Zhang Yuanyi said: "But there's no need for him to leave! Why don't you just ask me if you don't understand anything?"

Lin Yuan smiled and said, "A mathematician is often like a child. Do you know a famous mathematician named Hardy?"

Zhang Yuanyi said: "People who have studied Riemann's conjecture must have heard of Hardy, but he was only 1896 years old in 19, and he was still studying at Trinity College, Cambridge University. He devoted his life to overcoming Riemann's conjecture. , with many great achievements.”

Lin Yuan said: "Well, this is Hardy, he is an honest and upright person, but once he sent a letter to a good friend of his, which said: I have proved the Riemann conjecture, but the fact It’s because he didn’t prove it at all, so tell me what’s going on?”

Zhang Yuan shook his head, Lin Yuan smiled and said: "The thing is like this, it turns out that Hardy needs to cross the rough North Sea by boat to return to England. He was very scared, so he mailed such a letter. His reason It's like this: If the ship capsizes and he dies, the world will think that he proved the Riemann conjecture, so that he will get great honor, but God hates him very much, because he has never believed in the existence of God, so God He won't be given such an honor, so there won't be an accident with his ship."

After Lin Yuan finished speaking, he laughed. Unexpectedly, Zhang Yuan slapped his thigh and said, "Hardy is indeed a great mathematician. This trick is really ingenious! I used to be afraid every time I went out to fly, but now Alright, I’ll use this trick, and I won’t have to be afraid anymore.”

Lin Yuan thought helplessly: "It seems that the realm of genius is really beyond the comprehension of ordinary people." Lin Yuan continued: "Well, I will ask Beijing Ship to send the paper on Riemann's conjecture. You must read it. Pass it? You learn the symbols inside, then rewrite what you wrote, and send it to Hilbert."

Zhang Yuanyi said: "I have memorized that paper, but what I read is the modern version, and the symbols have been changed." Lin Yuan then handed the paper to Zhang Yuanyi, and then returned to his Room.

Early the next morning, Lin Yuan came to look for Zhang Yuanyi. When he came to the door and was about to push the door in, he saw a note pasted on the door, which read: "If you are not Lin Yuan, please ignore this piece of paper. If you are Lin Yuan, please open the door gently, there is the modified content on the table, you can send it out directly, in addition: I will not went."

Lin Yuan smiled helplessly, went in and took out his manuscript, handed it to an attendant to send to Hilbert, then went to find Shen Wanqing, knocked on the door twice, Shen Wanqing opened the door, Said to Lin Yuan: "I know what you are looking for me for, whether you are going to the technology fair to get information, I have already prepared it."

As Shen Wanqing said, she walked outside with Lin Yuan, and said as she walked, "Do you think we will see naval technology at the expo? Don't they know how to keep it secret?"

Lin Yuan said with a smile: "Military technology, if you put it in front of you and show you its appearance, you can't steal anything, and this William II is very face-saving, maybe he will come up with some good things."

Shen Wanqing said: "But there are many advanced technologies that will be used on warships. What exactly do we want to see?"

Lin Yuan said: "Although there are many technologies used on warships, they have to be divided according to the general direction, which can be counted on one hand. Power, weapons, fire control, protection, and communication are the five major technologies. Once we have mastered their technology, we can design warships in a targeted manner."

Many people in the mission also wanted to go to the exposition, so Germany sent more than a dozen cars, and a group of people came to the venue of the exposition—Museum Island in Berlin, which is a world-famous museum sanctuary. There are several famous The museum, this time the exposition was not held in the museum, but the exhibition location was chosen outside. It is not yet time to open to the public, so there are almost no tourists inside.

When Lin Yuan saw the booths one after another inside, he completely understood that the Germans just wanted to show us their prestige, telling us that their Germany is very powerful, and China had better be obedient. The accompanying German officials then said: "Our Emperor Your Majesty has something to do now, so I can't accompany you on the tour, you can take a look for yourself first, the military technology exhibition is at the bottom, if you have anything to ask, please feel free to contact me."

Lin Yuan nodded, and gave everyone an order to find what they like to see. Most people are not interested in military technology, so only Lin Yuan took Shen Wanqing to the innermost place. I heard Xu Jingcheng's voice behind me: "Master Lin, I still say the same thing. The Qing Dynasty can't build warships. I'll take you to see the German technology and you will understand."

Lin Yuan didn't refute him, but smiled lightly. The three of them walked to a booth. Xu Jingcheng pointed to the things on the table and said, "Look at that small ball with a frame, how exquisite it is! Our Daqing Can't make something like this, just don't know what this thing is for?"

Lin Yuan glanced at it and said, "That's just a gyroscope, I'll give it to them..." Lin Yuan felt a pain in his hand when he said this, and realized that it was Shen Wanqing who was pinching himself, and then remembered, When I demonstrated to the Europeans, I had disguised myself. If Shen Wanqing hadn't reminded me, I would have missed it.

Xu Jingcheng asked again: "What is a gyroscope?"

Hearing Xu Jingcheng's words, the person behind the booth said quickly: "Hello, Chinese friends, we are the service personnel of Pulan Company, and I will introduce this magical machine to you."

Lin Yuan was also surprised when he heard about Pulan Company, because this company is really unusual. In history, this company was not well-known, like Krupp Company and Armstrong Company. The company's products have completely rewritten the history of naval warfare!
