The legend of the king of crossing

Chapter 225 The Time of the Clock

"Hey," where is there any ancient book, I can only smile and say, "This is the secret of the Great Immortal,"

"Tch, brother, pretend again, forget it, ignore you, Sister Lin, your matter is clear, with my brother here, don't worry, let's go, I will take you to see the scenery of Lin'an, "

"kindness,"

"Brother, wait for us here, and invite sister Lin to eat your private kitchen at night,"

"Private cooking," 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 still wants to hear your ditty."

Lin Ying didn't say no this time, she blushed and whispered, "Elder, then let's go first,"

"Elder, my elder has come true," I said to myself after Fang Ling left.

I took a sip of tea, stood in the room and walked a few steps back and forth, took out the mask from my arms, put it on slowly, then walked to the mirror, took a look at it, and thought, "This is not an elder, right? "

"Xiaoqi, what time is it?"

"My lord, the application time has not yet come," Xiao Qi's answer came from outside the door.

"It's still early, Xiao Qi, call Mr. Shang to Lin'an University to see their new laboratory,"

Lin'an University was updated on the basis of the original Gongyuan. Although the space is limited, the university's laboratory is several times larger than the private laboratory built by Quanjue in "Qiuquan Villa".

The university is very close to Shifeng Commercial House, both near the imperial palace. When I arrived, Quanjue was instructing students to do experiments. This is an open-ended experiment class. The students were talking about it while doing the experiment, and no one noticed. my arrival.

With sharp eyes, Quan Jue walked to the door and said, "My lord, why are you here?"

"I'll take a look at your lab,"

"My lord, this place is still too small. In the planning of the school's new site, the laboratory will be bigger. There are laboratories for teaching and laboratories for scientific research. In addition, the Royal Academy of Sciences planned next to the school will also be built. It belongs to my own laboratory," Quan Jue envisioned.

"Well, the laboratory must be built to be the most advanced in the world, Quanjue, there is no need to save money here,"

"Yes, sir,"

"Where is Mr. Shen?"

"My son, sir is currently interviewing. Recently, many talents have come to the university to apply, some want to be a gentleman, some want to come to do scientific research, and some local government officials have also recommended people to come. The sir is busy with these things recently. "

After hearing this, I frowned slightly and said, "Quanjue, why do you need Mr. Shen to go to the interview in person?"

"Oh, son, it should be called a re-examination. After the re-examination, the master and the principal will make a decision together."

"That's okay, I'll go and have a look,"

"Well, young master, there happened to be a young man retesting today. He is a skilled craftsman, but I don't know if he is worth it. My young master just went to show it to me," Quanjue said to a student who was doing the experiment: " Si Xiao, "

"The students are here,"

"Zheng Sixiao, take this young master to the recruitment room to find the next two principals,"

"Yes, sir,"

The student named Zheng Sixiao was about the same age as me, in his 20s, studying in the Department of Physics, and looked a little slim, but his expression was rather haughty.

Not long after, Zheng Sixiao took us to the door of the recruitment room: "My lord, this is it, Yiweng (Zheng Sixiao's word) has to go back to class, so I won't accompany you in."

"Well, you go on your own,"

I knocked on the door and entered, and seeing that He Ji was not there, I sat next to Shen Yiqiu, and at the same time stretched out my hand to signal him to continue.

Shen Yiqiu got up and nodded at me, then started the interview again.

"Yang Xiaozhi, show your work,"

"Yes," Yang Xiaozhi set up a doll beside him and said, "Sir, this doll made of iron and wood can imitate human movements."

"Robots," I thought to myself.

Under Yang Xiaozhi's control, the puppet danced. The puppet's movements were flexible. Although the joints were a little sluggish, overall it was smooth.

Shen Yiqiu looked at it for a while and said again: "Can I do other movements?"

"Okay," Yang Xiaozhi adjusted the doll a few times, and this time the doll began to serve water and tea again.

"En, 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, thought I was also a university teacher, and said, "Sir, this is also a family skill."

"Family biography, tell me carefully,"

"My Yang family lived in Lin'an. In the Tang Dynasty, an ancestor named Yang Wulian liked puppet skills, and developed a monk-like robot. It held a bronze bowl in its hand and could learn from a monk to make alms. It can automatically collect the money, and at the same time, bow to the benefactor. 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 the Five Classics, so that Earn fame, but I liked this way since I was a child. I was dismissed by my parents as not doing a good job. After my father passed away, I have no other skills. I only have this ancestral skill. You can concentrate on your research."

The records about robots first appeared in the Spring and Autumn Period and the Warring States Period. Although the robots invented by skilled craftsmen in ancient China were nothing more than robots, the exquisite design of the equipment and the superb mechanical technology are unimaginable even for modern people. It's amazing, but most of these inventions and creations in our country have not been carried forward, so that they are slowly submerged in the long river of history.

This is a kind of sadness, just like gunpowder, invented by our ancestors, but Westerners made foreign guns and cannons, and turned their guns on China.

"Well, Yang Xiaozhi, can you show me the internal structure of your robot?"

Yang Xiaozhi hesitated for a while and said, "Okay."

I walked over and looked at the dissected robot up close. "The mechanical devices here are mainly gears or gear sets."

Yang Xiaozhi was surprised and said: "Exactly, Mr. Mo Fei also understands this."

I smiled and said nothing, suddenly my mind moved, I turned back to my seat and said, "Yang Xiaozhi, do you know the astronomical platform I'm facing?"

In the 11th year of Zhezong Yuanyou (1088) in the Northern Song Dynasty, Su Song, who was then the Minister of the Ministry of Officials and a Bachelor of Attendance, and Han Gonglian, the history of the Ministry of Officials, developed a large-scale instrument and equipment "Water Transport Instrument Platform". Complicated mechanical device, the whole mechanical system is powered by clepsydra flowing water, so that the instrument is always kept at a constant speed, consistent with the movement of the celestial body, and the various movements required are obtained through a complex gear system, so as to achieve It can not only demonstrate astronomical phenomena, but also time and tell time in various forms. People call this instrument "astronomical clock", and the clocks and watches of later generations evolved from here.

"I know, I have seen it in a book called "Xin Yi Xiang Fa Yao". The robots below are far from comparable, "

The astronomical observatory was invented with the efforts of the country, and of course it cannot be compared by Yang Xiaozhi alone.

"Yang Xiaozhi, what do you think is the difference between your robot and this instrument?"

"Sir, I have carefully studied the "Xin Yi Xing Fa Yao", and I think the use of gear devices is not inferior. As for the differences, I think there are three points. The precision of the instrument is beyond my ability, and the third is that I don’t have so many delicate 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, there is one more thing besides financial resources. I heard that there are many capable people in the university, so I want to use collective power to make my robots better,"

"Okay, let's go to university. The trial period is three months. Mr. Shen will tell you the details. The project I give you is not a robot, but a clock,"

"A clock, what is it?"

"In simple terms, a clock is a kind of timer that uses the energy released by a weight or spring as power to drive a series of gears, adjust the speed of the gear train with the escapement governor, and use the pointer to indicate the time and measure the time. The astronomical spheres and armillary spheres we are talking about have the function of timing, but they are large in size and high in cost, so they are not applicable at all. The clocks and watches I am talking about are much smaller. After class is over, we will go to the laboratory to discuss again."

Shen Yiqiu said: "I guess it's time to dismiss the get out of class."

I laughed and said, "If you have the clock I mentioned, you can judge the time relatively accurately."

In England in 1283, the first mechanical clock driven by weights appeared in a monastery in history. Then, in the 13th century in northern Italy, a group of monks built a clock tower. Now it is the Song Dynasty in 1265. Regardless of technology or The economy must be ahead of the West, plus I, a traveler, should be able to develop the world's first mechanical clock no matter what.

"Young Master, you're back," Quanjue said, the experimental class was over, and Zheng Sixiao was the only one left in the lab who was still asking Quanjue for advice.

"Well, Quanjue, let's talk about the new watch project," I casually found a chair and sat down.

"Yes, sir,"

"Mr. Quan, can the students listen together," Zheng Sixiao asked beside him.

I know that the learning atmosphere of Lin'an University is open. Apart from my major, I can sit in on courses of 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 However, secret projects such as guns are not disclosed to students, although these students have ID cards and have been verified by the Ministry of Housing.

Seeing me nodding my head, Quan Jue said to Zheng Sixiao, "Okay."

I said: "A clock is composed of a prime mover, a drive train, an escapement governor, a pointer system, and a winding needle system. The escapement governor is driven to work through a transmission system composed of a set of gears, and then the escapement governor controls the rotation speed of the transmission system in turn. The transmission system drives the pointer mechanism while driving the escapement governor. The speed of the drive train is controlled by the escapement governor, so the pointer can indicate the time on the dial according to certain rules, and the winding needle system is the mechanism that winds up the mainspring or moves the pointer."

After I finished speaking, seeing that everyone didn't understand, I said again: "Quanjue, take a pen and paper."

I drew a simple diagram of the transmission of a wall clock on paper: "This is a kind of clock, you see, this is a pendulum, this is a gear set, and this is an indicator needle,"

"Sir, these gear sets don't seem to be complicated," said Yang Xiao, who is extremely sensitive to gears.

"Well, the principle of the clock's gear is not complicated, the key is its accuracy, but 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, "

Quanjue is very good at such ingenious gadgets, after looking at the blueprints for a while, he asked, "My lord, what should I do with this pendulum?"

"Quanjue, 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 does not change. Well, I will leave the rest to you, Yang Xiaozhi. , this watch project will be handed over to you, this project is the test question for your probationary period, Quanjue, you are in charge of guiding, "

"Yes, sir,"

"Yes, sir,"

Quanjue and Yang Xiaozhi replied 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."
