It seems that I am still too full [travel]

If it is said that Xie Shi could tell some of the principles and calculation formulas of the sextant, but he couldn't tell the reason for the following objects.In fact, this object is not a modern high-tech product, but a daily necessities that are often encountered in modern times in the past, but the key point is that clocks and watches are common, but it is estimated that few modern people know how to make them?

The two craftsmen of the glass workshop took orders and retreated with the sketch given by Xie Shi.Xie Shi turned around and looked at the remaining three craftsmen. These three craftsmen were obviously different from the two glass workshop craftsmen who left just now. They all wore plain robes, unlike ordinary craftsmen, and their demeanor was neither humble nor overbearing.

The leader of the three is an old man with a long beard. He is over sixty years old. His body looks strong and there is a fresh air between his eyebrows. Shrunk, when seeing Xie at this time, it seems that this person also took the initiative to cup his hands and said, "What are your orders, young master?"

"Have you asked your name, sir?"

"I don't dare to ask you, sir, the villain's surname is Su, and the two behind me are my apprentices. They are not good at learning, and I hope to serve you."

Xie Shi raised his eyebrows, the relationship between these three people met his guess.After exchanging each other's surnames, he cut to the chase and asked directly: "Mr. Su, I wonder if you've heard of the Water Transport Observatory?"

The Water Transport Observatory sounds mysterious, and its origin is indeed extraordinary. It is said that it is the first astronomical clock in the world. The astronomical clock in the European Middle Ages was born here. It was created by Su Song and Han Gonglian in the Northern Song Dynasty. It is driven by water. It is an automatic instrument that can be used for astronomical observations, demonstrations, and most importantly, it can also tell the time. It is also known as the fifth great invention of ancient China.

Xie Shi occasionally sighs at this. The ancient ancestors of Huaguo have always been at the leading level in the world in mechanical creation. Unfortunately, most of the great inventions are just short-lived and have not been applied on a large scale, and they have not been taken seriously. As a result, Europe But people secretly learned these technologies and improved them, and when the national power grew stronger, they invaded China.

The reason why Xie Shi messed with this thing was because although the sextant at the front solved the problem of precise positioning of mid-latitude during navigation, he found that the establishment of longitude was the real problem. It can be estimated by the speed of the ship. How far the ship has traveled in the sea and where it has arrived is actually a metaphysics based on experience.

In order to establish accurate longitude, satellite positioning could not be used in ancient times. The simplest and most practical way is to rely on time. This is a relatively simple high school geography problem. By comparing it with the transit time of the sun at a known location, we can know If there is a longitude difference between the ship and the known location, for example, if the time of climax is measured one hour earlier, then it can be known that the ship is [-] degrees east of the known location, so that the latitude can be determined with the sextant, and finally The safety of ocean navigation is greatly improved by comparing and positioning the sea chart.

The hourglass cannot determine the exact time, so Xie Shi pondered for a long time, and then went to ask the two Mr. Song who were still in the Han family to celebrate the New Year, and learned that Wei Guogong of the previous dynasty had built a water transportation observatory, which could realize what Xie Shi said The daily automatic timekeeping function.

Xie Shi didn't know who this Wei Guogong was at first, but he had some impression of the water transport instrument platform mentioned by the two gentlemen. Isn't this the first astronomical clock in ancient China!Although I heard that this thing is a huge thing, and it is driven by water power, which is far from the small clock Xie Shi envisioned, but it's okay, as long as the thing exists, otherwise he really doesn't know how to "invent" this clock, after all these The knowledge of mechanical instruments is really super class for agricultural students.

When Mr. Su heard it, "Young Master, what you are talking about is the armillary sphere made by Su Song and Han Gonglian in the previous dynasty?"

Xie Shi nodded, and suddenly thought, this old gentleman's surname is Su, and according to Mr. Song, this Su Song is also from Quanzhou, Fujian, so there is no relationship between the two, right?

Knowing Xie Shi's speculation, Mr. Su explained with trepidation: "Misunderstanding, my ancestor was a loyal servant of the Duke of Wei, and was fortunate to be given a surname. He is not a descendant of the Duke of Wei." There is still such a relationship. Xie Shi added a little more confidence in the matter of replicating the clock!

Xie Shi unfolded several kinds of clock diagrams he had drawn and explained them to him. Among them, there were grand pendulum clocks and pocket watches.In fact, there is nothing to explain. After all, Xie Shi knows nothing about it, so he can only make two demands on the three of them from the perspective of demand. One is that the clock can automatically and accurately tell the time, and the error should not exceed two quarters of an hour, which is half an hour. ; The [-]nd, small and exquisite portable, just can't be practically applied in the navigation as the gigantic thing that reaches more than ten meters like the astronomical instrument platform.

Hearing Xie Shi's request, the faces of the two apprentices changed. Obviously, both of them thought that this was a fantasy. How could it be possible to shrink a monster more than ten meters high to an inch, and change the hydraulic drive to mechanical drive!If the person in front of him wasn't an honored person whom even the head of the family regards as a guest of honour, these two young craftsmen would probably curse out of their mouths.

Xie Shi quickly reassured him, saying that he was definitely not full of food and had nothing to do, deliberately making things difficult for others, "I know the difficulty of making this machine, I just want to invite skilled craftsmen to try it, if it doesn't work, I won't blame a few people Whether it is successful or not, as long as everyone can improve the machines of the predecessors, I will reward you."

Elder Su had been looking at the drawings thoughtfully, and suddenly asked: "May I ask you, where did you get the drawings? If someone can guide the internal structure, I think I will be more confident."

Xie Shi felt embarrassed, where would he find a modern watchmaker to guide them, he is the only "expert" nowadays, but he is a fake expert, purely a layman.

"I got this from an overseas fan, and now I have nowhere to find a craftsman who can make this object. I only know that the principle of this object is the same as that of the aquarium, and the structure must be similar."

When Mr. Su heard that it was something from overseas, he couldn't help being amazed, and exclaimed: "Can Fanren actually make such an exquisite thing now?!" After he finished speaking, his fighting spirit seemed to be aroused again, and he said: " Fan people are stupid, and those who come from behind can still achieve this kind of skill, it doesn't make sense that no one in my vast country can make it, my son, please let me take this blueprint back to study for a period of time, and then I will report back to you."

Xie Shi was naturally happy to see the success, and before leaving, he gave Mr. Su the copy of "Shao Shengyi Xiang Fa Yao" that Mr. Song found for him through looking through the classics. This book was written by Su Song, and it was clearly recorded in it. The steps and drawings of making the astronomical observatory, I hope it can give this old gentleman some reference.

Before leaving, Xie Shi kept sending them to the gate of the courtyard, stood on the porch and watched the three masters and apprentices go away, sighing in his heart, the ancient Chinese craftsmen were not without the ability to invent and create, but their craftsmanship only served the pleasure of the nobles. The low status has not been taken seriously, so after the beginning of the age of great exploration, Europe came from behind and took the lead.

"Mister seems to attach great importance to these craftsmen?" Han Ning, who had been watching Xie Shi discussing the art of creation with several craftsmen, suddenly said.

Xie Shi turned around and the two walked back.He didn't answer Han Ning's question, but raised a question, "Does Brother Ning think these craftsmen are important?"

This question caught the young man Han Ning. According to the scholarly education he has received all along, among scholars, farmers, businessmen, Confucian scholars are the most noble and preside over state affairs. Farmers are the foundation of the country. .It is precisely through doing business that the Han family became so wealthy. Of course, Han Ning does not agree with the saying that businessmen are inferior, but after thinking about craftsmen, Han Ning seems to think that they are not very important to the country or the people. effect.

Xie Shi didn't make things difficult for him, but just told him a story, a true story that happened in history.

"Once upon a time, there was an ancient country. She was surrounded by the whole world and had a splendid culture with a long history of 5000 years. She stood on the top of the world with the peak of national power, and let all nations come to court and worship from all directions. She has many great inventions and is ahead of the world. But the people who manage this country regard it as a strange skill, a thing for entertainment, and think that it should not be indulged in playthings.

"Gradually, many great inventions and creations were lost, some were banned, and some were secretly learned by people from a small country on the other side of the mainland. These people improved these precious technologies and developed academic knowledge. Later, the quantitative change led to a qualitative change. They set off a big change in the handicraft industry, developed a mechanical workshop, replaced manpower with machinery, and the output increased by more than ten times. The small domestic market could not absorb the soaring output...

"In order to open up overseas markets, they finally set their sights overseas, the most fertile territory on the other side of the mainland - the ancient oriental country that was closed to the outside world. The industrial revolution was carried out, and the small states with strong ships and powerful guns were united. , easily blasted open the gates of the ancient country with backward weapons and no thought of progress, and brutally enslaved [-] million people in the state of etiquette. The ancient country is facing great changes unseen in thousands of years, the mountains and rivers are broken, and the country will not survive..."

When Xie Shi said this, he stopped. Instead, Han Ning, who was fascinated by listening, followed up and asked: "Sir, what happened later? That ancient country defeated the enemy country and regained the mountains and rivers?"

"Guess?" Xie Shi teased him with a smile, his casual attitude made the calm and introverted boy anxious.

"I guess, they won the battle of destroying the country." A deep and cold voice came from the side, Xie Shi looked back, and saw Han Ji standing in the corridor not far away, followed by Cen Yu and Qiu Zhi A group of people, seeing Xie Shi, saluted him. It was obvious that they had already arrived when they were telling Han Ning a story, but they just kept silent.

Xie Shi looked at Han Ji, and suddenly smiled brightly, with infinite pride, "Yes, even if they paid the heavy price of 500 million blood-stained mountains and rivers, and the country was riddled with holes, they won, and they won again. stand in the east."

Xie Shi's story sounds like a random fabrication. After all, throughout the ages, many dynasties may have a population of less than 500 million. How could it be possible for so many people to be killed or injured in wars? Moreover, if there is such a powerful country, it is impossible not to Heard, silent and nameless.But after hearing this, Han Ji and his party were thoughtful, and Cen Yu thought to himself, there is no such thing in this world, but who can say that this is not something that happened in another world?Xie Tanwei is a little fairy with extraordinary background!

Several people walked into the hall to talk, Xie Shi asked: "Brother Ji, did you have something to do with me?" Judging by their posture, they came out of the study just after talking about something.

Sure enough, Han Ji said: "As soon as Qi and the others come back, do you want to go to the tower together to welcome the soldiers who have returned from victory?"
