"Hey," there was no ancient book anywhere, I could only smile and said, "This is the secret of this great immortal,"
"Tch, brother, just pretend again. Forget it. I'll ignore you. Sister Lin, your matter is clear. My brother is here, so don't worry. Let's go. I'll take you to see the scenery of Lin'an. "
"kindness,"
"Brother, wait for us here, and treat Sister Lin to your private kitchen tonight,"
"Private kitchen," Lin Ying said in surprise.
"Yeah, let's go, I'll tell you on the way," Fang Ling said with a smile, "Also, brother, Sister Lin said she also wanted to hear the little song you sang,"
Lin Ying did not say no this time. She blushed and whispered: "Elder, let's go first."
"Elder, my elder has become real," I said to myself after Fang Ling left.
I took a sip of tea, stood in the room and walked a few steps, took out the mask from my arms, slowly put it on, then walked to the mirror, took a look, and thought to myself, "I'm no longer an elder now. "
"Xiaoqi, what time is it?"
"Sir, the time has not come yet," Xiao Qi's voice came from outside the door.
"It's still early, Xiaoqi, call your husband and go to Lin'an University to see their new laboratory,"
Lin'an University was updated on the basis of the original Gongyuan University. Although the space is limited, the university's laboratory is several times larger than the private laboratory built by Quan Jue of "Qiuquan Villa".
The university is very close to Shifeng Commercial Bank, both near the palace. When I arrived, Quan Jue was instructing students to do experiments. This was an open experimental class. The students were talking about it while doing experiments, and no one noticed. my arrival.
Quanjue, with sharp eyes, walked to the door and said, "Sir, why are you here?"
"Let me see your laboratory,"
"Sir, this place is still too small. In the planning of the new school site, the laboratories are much larger. There are laboratories set up for teaching and scientific research. In addition, the Royal Academy of Sciences planned next to the school will also build A laboratory of my own," Quanjue said longingly.
"Well, the laboratory must be built into the most advanced one in the world. There is no need to save money here."
"Yes, sir,"
"Where's Mr. Shen?"
"Back to the young master, sir, you are having an interview. Recently, many talents have come to the university to apply for jobs. Some want to be teachers, some want to do scientific research, and some local governments have also recommended people to come. Sir, he has been busy with these recently. "
After hearing this, I frowned slightly and said, "Quan Jue, why do you need Mr. Shen to go to the interview in person?"
"Oh, sir, it should be called a re-examination. After the re-examination, the decision will be made jointly by your husband and the principal,"
"That's okay, I'll go over and have a look,"
"Well, Young Master, there happened to be a young man taking the re-examination today. He is a skilled craftsman, but I don't know if he is of any value. Young Master just happened to go and have a look." Quan Jue finished speaking and said to a student who was doing the experiment: " Sixiao,"
"Students are here,"
"Zheng Sixiao, take this young man to the recruitment room to find the two principals,"
"Yes, sir,"
The student named Zheng Sixiao is about the same age as me, in his twenties, studying in the Department of Physics. He looks a bit thin, but his expression is quite arrogant.
Not long after, Zheng Sixiao took us to the entrance of the recruitment room: "Master, this is it. Yiweng (Zheng Sixiao's character) has to go back to class, so he won't accompany him in."
"Well, you can go on your own,"
I knocked on the door and entered. Seeing that He Ji was not there, I sat next to Shen Yiqiu and stretched out my hand to signal him to continue.
Shen Yiqiu stood up and nodded to me, then continued the interview.
"Yang Xiaozhi, show me your work,"
"Yes," Yang Xiaozhi stood up a doll next to him and said, "Sir, the doll below is made of iron and wood and can imitate human movements."
"Robot," I thought to myself.
The puppet danced under Yang Xiaozhi's control. The puppet's movements were flexible, and although the joints were slightly sluggish, it was generally smooth.
Shen Yiqiu looked at it for a while and then said: "Can I do other actions?"
"Okay," Yang Xiaozhi adjusted the puppet a few times, and this time the puppet started carrying water and tea again.
"Well, not bad," I praised, "Yang Xiaozhi, how did you come up with the idea of making this doll?"
Yang Xiaozhi didn't know who I was and thought I was also a university teacher, so he said, "Sir, this can be considered a family skill."
"Family history, tell it carefully,"
"My Yang family lives in Lin'an. During the Tang Dynasty, an ancestor named Yang Wulian was fond of puppet techniques and developed a robot that looked like a monk. It held a copper alms bowl in its hand and could imitate the monks' alms alms. When the bowl was full of money, it would return I can automatically collect the money and at the same time bow to the donor. Since then, this skill has been passed down. In my father's generation, the family was not prosperous. My father hoped that I could read the Four Books and learn the Five Classics. Earning fame is something I have liked since I was a child, but my parents criticized me for not doing my job properly. After my father passed away, I had no other skills, only this ancestral skill, so I came to the university to apply for a job, firstly, I could make a living, and secondly, You can concentrate on your research,"
Records about robots first appeared in the Spring and Autumn Period and the Warring States Period. Although the robots invented by ancient Chinese craftsmen were just robots, the exquisite design of their equipment and the superb mechanical technology were incredible even to modern people. It's amazing, but most of these inventions and creations in our country have not been able to be carried forward, and they have been slowly submerged in the long river of history.
This is a tragedy, just like gunpowder, our ancestors invented it, but Westerners made foreign guns and cannons, and in turn pointed the guns at China.
"Well, Yang Xiaozhi, can you let me see the internal structure of your robot?"
Yang Xiaozhi hesitated for a while and said: "Okay,"
I walked over and looked at the cut-up robot up close, "The mechanical devices inside are all mainly gears or gear sets,"
Yang Xiaozhi was surprised and said: "Exactly, Mr. Do you know this too?"
I smiled and said nothing, but suddenly a thought came to my mind. I turned back to my seat and said, "Yang Xiaozhi, do you know about the water transport ceremonial platform in my court?"
In the 11th year of Yuanyou (1088), the reign of Emperor Zhezong of the Northern Song Dynasty, Su Song, who was the Minister of the Ministry of Civil Affairs and a bachelor at the time, and Han Gonglian, the Huishi of the Ministry of Civil Affairs, and others developed a large-scale instrument and equipment, the "Water Transport Instrument Table". It is a complex mechanical device. The entire mechanical system uses the flowing water of the clepsydra as power to keep the instrument at a constant speed, consistent with the movement of the celestial body. It also obtains the various required movements through a complex gear system, thus It can not only demonstrate celestial phenomena, but also time and tell time in various forms. People call this instrument an "astronomical clock", and the clocks of later generations evolved from here.
"I know, I have seen it in a book called "New Yixiang Law Essentials". This is really a feat for me. It would be great if I could see the real thing," Yang Xiaozhi said with some envy and some disappointment, " The robots below are far incomparable,"
The water transport instrument platform was invented by the collective efforts of the country, and of course it cannot be compared to what Yang Xiaozhi could do alone.
"Yang Xiaozhi, what do you think is the difference between your robot and this instrument?"
"Sir, I have carefully studied the "New Instruments and Symbols", and I think that the use of gear devices is not inferior. As for the difference, I think there are three points. One is that the grandeur of the water transport instrument platform is beyond my reach, and the other is that The accuracy of the instrument is beyond my ability, and thirdly, I don’t have so many exquisite gears.”
I laughed when I heard the third point: "So you want to join Lin'an University and rely on the university's financial resources to realize your dream,"
"Yes, in addition to financial resources, I heard that there are many capable people in the university, so I want to use collective strength to make my robots better,"
"Okay, then enter the university. The probation period is three months. Mr. Shen will tell you the specifics. The project I give you is not a robot, but a clock."
"What is a clock?"
"Simply speaking, a clock is a timepiece that uses the released energy of a heavy hammer or spring as power to push a series of gears, adjust the speed of the gear train with an escapement governor, and use hands to indicate and measure time. Like just now The water transport instrument platform and armillary sphere we are talking about have the function of timing, but they are large in size and expensive, so they are not suitable at all. The clock I am talking about is much smaller. By the way, have you finished class? If so After class, we will go to the laboratory to discuss it again,"
Shen Yiqiu said: "I guess it's time for get out of class to end."
I smiled and said, "If I had the clock I mentioned, I would be able to judge the time relatively accurately."
In England in 1283, the first mechanical clock driven by weights appeared in a monastery in history. Then, in northern Italy in the 13th century, a group of monks built a bell tower. Now it is the Song Dynasty in 1265. Regardless of technology or The economy must be ahead of the West, and with me as a time traveler, I should be able to develop the world's first mechanical clock.
"Young Master, I'm back," Quan Jue said. The experimental class was over, and Zheng Sixiao was the only one left in the laboratory still asking Quan Jue for advice.
"Well, Quan Jue, let's talk about this new project of clocks," I said, finding a chair and sitting down.
"Yes, sir,"
"Mr. Quan, can students listen together?" Zheng Sixiao said at the side.
I know that the learning atmosphere of Lin'an University is open. In addition to my own major, I can attend courses in other majors at any time. At the same time, I can also choose scientific research projects that I am interested in in my spare time. As long as the project leader approves, I can become his assistant. Of course , secret projects such as firearms are not disclosed to students, although these students have identity documents and have been verified by the Ministry of Household Affairs.
Quan Jue saw me nodding and said to Zheng Sixiao, "Okay."
I explained: "A clock is composed of a prime mover system, a transmission system, an escapement regulator, a pointer system and a winding dial system. The principle of a mechanical clock is roughly to use a spring as the prime mover system. The escapement speed regulator is driven by a transmission system composed of a set of gears, and the escapement speed regulator in turn controls the rotation speed of the transmission system. While driving the escapement speed regulator, the transmission system also drives the pointer mechanism. The rotation speed of the system is controlled by the escapement speed regulator, so the pointer can indicate the time on the dial according to a certain pattern. The winding dial system is a mechanism for winding up the spring or moving the pointer."
After I finished speaking, I saw that no one understood, so I said again: "Quan Jue, get a pen and paper,"
I drew a simple schematic diagram of the transmission of a wall clock on paper: "This is a type of clock. Look, this is the pendulum, this is the gear set, and this is the indicator hand."
"Sir, these gear sets don't seem too complicated," said Yang Xiaozhidao, who is extremely sensitive to gears.
"Well, the gear principle of a clock is not complicated. The key is its accuracy. However, this is only the simplest. If it is to be accurate to one word or even less in the future, the gear set will be quite complicated. "
Quan Jue was very good at such ingenious gadgets. He looked at the drawings for a while and asked, "Sir, how should I make this pendulum?"
"Quan Jue, I can't tell you the specific details. This is exactly what you need to do research on. I can only tell you that the swing time of the pendulum remains unchanged. Okay, I'll leave the rest to you, Yang Xiaozhi , this clock project will be left to you. This project is the test question for your probation period. Quan Jue, you are responsible for guiding, "
"Yes, sir,"
"Yes, sir,"
Quanjue and Yang Xiaozhi answered at the same time.
When I left, I vaguely heard Zheng Sixiao's voice, "Mr. Quan, who was that gentleman just now? He seems to be very knowledgeable."
