Chapter 225 Clocks in Progress

"Hey, hey." Where is there any ancient book, I can only smile and say, "This is the secret of this great immortal." ”

"Cut, brother, you pretend again, forget it, ignore you, Sister Lin, your affairs are clear, with my brother here, you can rest assured, go, I'll take you to see the scenery of Lin'an."

"Yes."

"Brother, wait for us here, and invite Sister Lin to eat your private dishes here in the evening."

"Private dishes." Lin Ying said in surprise,

"yes, let's go, I'll tell you on the way." Fang Ling smiled, "Also, brother, Sister Lin said that she still wants to listen to the little song you sing." ”

Lin Ying didn't say no this time, and whispered with a red face, "Elder, then let's go first." ”

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

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

"Xiao Qi, what time is it?"

"Childe, the time has not yet arrived." Xiao Qi's response came from outside the door,

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

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

The university is very close to the Shifeng Trading House, all near the palace, when I arrived, Quanjue was instructing the students to do experiments, it was an open experimental class, the students were doing experiments and talking a lot, and no one noticed my arrival.

Quanjue's eyes were sharp, and he walked to the door and said, "Childe, why are you here." ”

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

"Childe, this place is still too small, in the planning of the new site of the school, the laboratory can be large, there are laboratories for teaching, there are laboratories for scientific research, and the Royal Academy of Sciences planned next to the school will also build its own laboratory." Quanjue longed,

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

"Yes, Childe."

"What about Mr. Shen."

"Hui Gongzi, Mr. is interviewing, recently a lot of talents have come to the university to apply, some want to be a gentleman, some want to do scientific research, and some local governments have also recommended people to come, Mr. has been busy with these recently."

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

"Oh, Childe, it should be called a re-examination, and after the re-examination, Mr. and the principal will make a decision together."

"That's okay, I'll go over and see."

"Well, Childe, there happened to be a young man retaking the test today, he is a skilled craftsman, but I don't know if it is valuable, Childe just went to take a look." After Quan Jue finished speaking, he said to a student who was doing an experiment, "Si Xiao." ”

"The students are here."

"Zheng Sixiao, you take this son to the recruitment room to find the two principals."

"Yes, sir."

The student called Zheng Sixiao is the same age as me, in his twenties, studying in the physics department, looking a little clean, but his expression is quite arrogant.

It didn't take long for Zheng Sixiao to take us to the door of the recruitment room: "Childe, this is it, Yi Weng (Zheng Sixiao's character) has to go back to class, so I won't accompany Childe inside." ”

"Well, you can go by yourself."

I knocked on the door and entered, and when I saw 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, and then continued the interview.

"Yang Xiaozhi, show your work."

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

"Robots." I thought to myself,

The puppet danced under Yang Xiaozhi's stroke, the puppet moved flexibly, although it was slightly sluggish at the joints, but on the whole it was also smooth.

Shen Yiqiu looked at it for a while and said, "Can you still do other actions?" ”

"Yes." Yang Xiaozhi debugged the puppet a few times, and this time the puppet started to pour water and tea again.

"Yes, that's good." I praised, "Yang Xiaozhi, how did you come up with the idea of making this puppet?" ”

Yang Xiaozhi didn't know who I was, thinking that I was also a university teacher, and said, "This gentleman, this is also a family heirloom." ”

"Family heirloom, tell me carefully."

"My Yang family lives in Lin'an, in the Tang Dynasty, an ancestor named Yang Wulian liked puppet skills, and developed a monk-like robot, it holds a copper bowl in hand, can learn to be a monk, and wait until the bowl is full of money, but also automatically put away the money, at the same time, will bow to the donor, since then, this skill has been passed down, to my father's generation, the family is not prosperous, my father hopes that I can read the four books, learn the Five Classics, in order to win fame, and I like this way since I was a child, was reprimanded by my parents as not doing business, after my father's death, I don't have any other skills, only this ancestral skill, so I came to the university to apply for a job, first, to have enough to eat, and second, to concentrate on research. ”

The record of robots, first appeared in the Spring and Autumn Period and the Warring States Period, although the robots invented by skilled craftsmen in ancient China are just some robots, but the exquisite design of its equipment, the superb mechanical technology, even if it seems to modern people, it is incredible, breathtaking, but most of these inventions and creations in our country have not been carried forward, so that they are slowly drowned in the long river of history,

This is a kind of sadness, like gunpowder, which was invented by our ancestors, but was made by Westerners with foreign guns and cannons, and in turn aimed their guns at China.

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

Yang Xiaozhi hesitated for a moment and said, "Okay." ”

I walked over and looked at the dissected robot up close, "The mechanics in here are mainly gears or gear sets." ”

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

I smiled and said nothing, suddenly my mind moved, turned back to my seat and said, "Yang Xiaozhi, do you know the water transport instrument elephant platform I am looking to." ”

In the eleventh year of Yuanyou of Zhezong of the Northern Song Dynasty (1088), Su Song, who was then a scholar and a bachelor, and Han Gonglian, who was a scholar of the Ministry of Officials, and Han Gonglian and others developed a large-scale instrument and equipment "Water Transport Instrument Elephant Platform", this instrument is a complex mechanical device, the whole mechanical system is powered by the use of leaky pot flowing water, so that the instrument is often maintained at a constant speed, consistent with the operation of celestial bodies, and through a set of complex gear system to obtain the required various movements, so as to achieve both the demonstration of celestial phenomena, and can be in a variety of forms of timing, time, People called this instrument "astronomical clock", and it was from here that the clocks of later generations evolved.

"I know, I've seen it in a book called "New Ritual Elephant Law", this is really a feat for me, if only I could take a look at the real thing." Yang Xiaozhi was a little envious and a little disappointed, "The robots under it are far from being comparable." ”

The water transport instrument elephant platform was invented with the power of the country, of course, it is not comparable to Yang Xiaozhi alone.

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

"Sir, I have carefully studied the "New Ritual Method", 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 concept of the water transport instrument is beyond my reach, the second is that the accuracy of the instrument is beyond my reach, and the third is that I do not 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 fulfill your dream." ”

"Yes, in addition to financial resources, I heard that there are many talented people in the university, so I want to use the collective power to do better in the robots."

"Okay, then enter the university, the probation period is three months, and the specific thing is that Mr. Shen will tell you, the project I gave you is not a robot, but a clock."

"Clocks, what's it?"

"To put it simply, a clock is a kind of timer that uses the release energy of a hammer or spring as the power to drive a series of gears to run, adjust the speed of the wheel train by means of an escapement governor, and indicate the time and measure the time with the pointer.

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

I laughed and said, "If you had the clock I was talking about, you would be able to tell the time relatively accurately." ”

In England in 1283, a monastery appeared in the history of the first weight-driven mechanical clock, and then, in the 13th century in northern Italy, a group of monks built a bell tower, now in 1265 of the Great Song Dynasty, both technology and economy are ahead of the West, plus me, a traveler, how should I be able to develop the world's first mechanical clock,

"Childe, you're back." Quanjue said, the experimental class has ended, and only Zheng Sixiao is still in the laboratory who is still asking Quanjue what questions,

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

"Yes, Childe."

"Mr. Quan, can the students listen together?" Zheng Sixiao on the side said,

I know that the learning atmosphere of Lin'an University is open, in addition to their own majors, they can audit the courses of other majors at any time, and at the same time, in their spare time, they can also choose the scientific research projects they are interested in, as long as the project leader approves, they can become their assistants, of course, secret projects such as guns are not open to students, although these students have identity credentials, and they have been verified by the household department,

Seeing me nodding, Quanjue said to Zheng Sixiao, "Okay." ”

I recounted: "The clock is composed of the prime mover system, the transmission train, the escapement governor, the pointer system and the upper dial pin system, etc., the principle of the mechanical clock is roughly, the use of the mainspring as the power of the prime mover system, through a group of gears composed of the drive train to promote the escapement governor work, and then by the escapement governor in turn to control the rotation speed of the drive train, the drive train in the push escapement governor also drives the pointer mechanism, the speed of the drive train is controlled by the escapement governor, so the pointer can indicate the time on the dial according to a certain law, The upper pluck hand is a mechanism that tightens the spring or toggles the hands. ”

After I finished speaking, I saw that everyone did not understand, and said, "Quanjue, take a pen and paper." ”

I drew a simple diagram of the clock drive on paper: "This is a kind of clock, you see, this is the pendulum, this is the gear set, this is the indicator needle. ”

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

"Well, the principle of the gears of a clock is not complicated, the key is its accuracy, but this is only the simplest, if you want to achieve accuracy to one word or even less in the future, its gear set will be quite complicated."

Quanjue is very good at this kind of strange gadgets, and after looking at the drawings, he asked, "Childe, how to get this pendulum." ”

"Quanjue, I can't say the specific details, this is exactly what you need to do research, I can only tell you, the pendulum swing time is unchanged, okay, the rest will be handed over to you, Yang Xiaozhi, this clock project will be handed over to you, this project is the subject of your probationary period, Quanjue, you are responsible for guiding."

"Yes, Childe."

"Yes, sir."

Quan Jue and Yang Xiaozhi replied at the same time,

When I left, I vaguely heard Zheng Sixiao's voice, "Mr. Quan, who is the gentleman just now, it seems that he has a lot of knowledge." ”
