Both the Tang and Song dynasties had a ten-day holiday system, and officials had many holidays.
But by the Ming Dynasty, the ten-day holiday system was abolished, and the annual holidays totaled only more than fifty days. Moreover, New Year's Day, Lantern Festival, Zhongyuan Festival, and Winter Solstice accounted for the majority of these fifty-plus days of holidays, and there were basically no rest days.
It can be said.
Only the Hanlin Academy edited and edited it, excluding common people!
The new Jinshi who have just been admitted to the Hanlin Academy will have a five-day break, and they can also apply for eunuchs and guards to accompany them when they go out. However, when the three years are up, the next Jinshi will be released, and the special treatment of the previous one will be revoked.
Cancel.
Today is another holiday. Yang Shen said goodbye to his parents and wife after breakfast and planned to take a car to the Wang family mansion in the west of the city.
"Yongxiu!" Yang Tinghe called his son to stop.
Yang Shen, who had already walked out of the dining room, turned around and said, "Father, what are your orders?"
Yang Tinghe asked: "Have you been hanging out with Wang Erlang recently?"
"Exactly," Yang Shen replied, "In addition to Bachelor Wang, there is also the experience of Jinyi Guard Gu."
Yang Tinghe nodded in approval and said: "Both Wang and Gu are His Majesty's confidants. If we can win them over, they will be a considerable help in the future."
Yang Shen explained: "Father, my friendship with Bachelor Wang and Gu Xingcheng was purely academic exchange and had nothing to do with court politics."
"People who share the same ideals all start out as friends." Yang Tinghe said with a smile.
Yang Shen didn't bother to explain, so he just said a few words and went out in the carriage.
Yang Tinghe also went out with his servants and took a sedan chair to the imperial city for work. He was very satisfied with his son. Not only was he excellent, but he also made great friends. In the third year of Zhengde's Jinshi period, a large number of talents have emerged, and most of the outstanding ones are
He is a good friend of Yang Shen.
The biggest headache for Yang Tinghe now is the personnel department. No matter how hard he reaches, he can only get some insignificant positions.
Yang Yiqing firmly controlled the power of the Ministry of Personnel, and Li Dongyang also mixed in a lot of sand. Only he, Yang Tinghe, was helpless against the Ministry of Personnel.
Yang Tinghe can only be patient now until Li Dongyang takes office. At that time, he will be able to take over Li Dongyang's direct lineage. Those who don't follow will be thrown to Nanjing, and it will not be too late to turn around and fight with Yang Yiqing.
Yang Shen didn't have so many ideas. Young geniuses are always conceited and disdainful of trivial matters.
Without any communication, Yang Shen came directly to the laboratory, chatted with Du Jin, Bao Chaozhen and others for a while, and then started his study career today.
In the middle of the morning, Wang Yuan suddenly appeared and had several spinning wheels brought in.
Yang Shen didn't understand what he meant and asked, "What kind of experiment is Ruoxu doing?"
Wang Yuan explained with a smile: "In addition to exploring the mysteries of nature, when we study mathematics and physics, we also focus on benefiting all people. Why not use known physical knowledge to transform existing spinning wheel technology so that people can save time and create more wealth?
?”
As soon as this statement came out, Yang Shen, Du Jin and Bao Chaozhen were a little confused. In other words, they were also willing to benefit all people, but they just did it casually and wasted their research time to make inventions. In their view, they were neglecting the basics and chasing the last.
If Wang Wensu had not served in the Ministry of Household Affairs, he would have hit it off at this time. The original intention of this gentleman's study of mathematics was to spread mathematics widely and benefit all people. To this end, he also racked his brains and compiled various mathematical methods into songs to make the illiterate people
Everyone can speak catchy.
Although they do not support Wang Yuan's approach, Yang Shen, Du Jin and Bao Chaozhen cannot object. After all, this is Wang Yuan's laboratory and they are still learning from Wang Yuan.
Everyone put down their research projects and gathered around Wang Yuan.
Wang Yuan pointed to the two spinning wheels and said: "This is a single-spindle spinning wheel, which can only spin one bundle of silk cotton at the same time. It is mainly used by women at home. This is a three-spindle spinning wheel, which can spin three bundles of silk cotton at the same time. It is mainly used by official officials.
Weaving bureaus and folk textile workshops are using it. So, can we use physics knowledge to make a spinning wheel with more than four spindles?"
These days, China's textile technology is still very advanced. It can spin three spindles of silk floss at the same time, while Europe can only spin two spindles at most.
Yang Shen, Du Jin and Bao Chaozhen were immediately confused. They didn't even know how the spinning wheel worked. How could they have any ideas to improve it?
"Come in!" Wang Yuan clapped his hands.
Two maids from the royal family came in, sat in front of the two spinning wheels, and began to show the men how to use the spinning wheels.
After everyone understood, Wang Yuan smiled and said: "Please draw a mechanical diagram of the spinning wheel."
“This is fresh!”
Yang Shen, Du Jin and Bao Chaozhen immediately became interested and used mechanical diagrams to express the machines that could be seen in daily life. This was like engaging in academic research!
The three people squatted in front of the spinning wheel, repeatedly observed its work process, and worked together to draw a mechanical diagram.
But then we became troubled. Everyone focused on how to add devices and improve the efficiency of the spinning wheel. This thing cannot be achieved in a day or two.
Laboratory assistant Zhong An's mathematics level has been promoted from the third grade to the fourth grade of elementary school. He had attended the mechanics course before, but he only half understood it, and he had only a half understanding of the work diagrams drawn by everyone.
Listening to the heated discussion, the boy squatted down to step on the spinning wheel. Then he looked at the mechanics diagram and suddenly said weakly: "Well... can you put something under the pedals to make it easier for your feet to step on the pedals?
No matter how hard you try, you won’t be afraid of stepping too hard and not being able to hold it back.”
Yang Shen, Du Jin and Bao Chaozhen didn't take it seriously, because Zhong An's idea could not significantly improve the efficiency of the spinning wheel.
Wang Yuan also knew nothing about textile machines, but in order to increase Zhong An's enthusiasm, he still asked craftsmen to come over and make modifications. There were no major changes, just nailing a small wooden stake under the tread, which could be completed in a few minutes.
Then I asked the woman to sit down and spin cotton. The woman was pleasantly surprised and said, "It's so light now, and I don't have to worry about the strength on my feet."
From the Yuan Dynasty to the mid-Ming Dynasty, this kind of foot-operated three-spindle spinning wheel has been in use for nearly two hundred years. It not only requires the weaver's ingenuity, but also tests the strength and speed of the foot, and the work efficiency of skilled and novice workers.
There's a huge difference.
Just adding a small wooden stake under the tread can prevent excessive force when stepping on the tread and make the lifting wheel of the tread more flexible. Moreover, the leverage formed by the tread and the spokes drives the collars on the leather strings evenly
The rotation is more free, thereby greatly improving work efficiency, and the spun yarn and cotton sliver have a higher yield rate.
"Okay, you have a very flexible mind!" Wang Yuan praised with a smile.
Zhong An scratched his head and giggled: "I have never touched a spinning wheel before. I just sat down and tried a few feet. Either the force was too strong or the force was too light. I thought, if there is something blocking it below, I won't be afraid of stepping too hard.
Already."
It's such a simple thing, but no one has improved it in the past two hundred years.
When all the novices started learning, they focused on how to control the force, but no one thought of adding a wooden stake underneath. This small change had to wait until after the Jiajing Dynasty, when the textile industry in the south flourished, and private merchants wanted to improve production efficiency.
Just discovered.
Since it is related to academics, it cannot be changed casually.
Wang Yuan took matters into his own hands this time to measure the various moment arms of the spinning wheel, the weight of the spinning wheel, etc. It took him two full days to finally measure the optimal height of the small wooden stakes and optimize the overall performance of the spinning wheel.
Unfortunately, since the spinning wheel is completely handmade, each spinning wheel is different, and how to install the small wooden stakes is definitely different. The data measured by Wang Yuan is only suitable for this spinning wheel. If it is popularized, it will all depend on the experience and experience of the craftsmen.
It’s craftsmanship.
Under Wang Yuan's testing and improvement, only one more small wooden stake was added. The spinning wheel that originally spun three bundles of silk at the same time could actually spin five bundles of silk floss at the same time. Moreover, the operation was more convenient, easier for beginners to get started, and the work was less complicated.
It consumes physical strength and energy, and the machine loss of the spinning wheel is also greatly reduced.
Work efficiency has probably increased by two to three times.
"This is your silver reward!" Wang Yuan personally handed the five taels of silver to Zhong An.
"Sir, I...I didn't do anything." Zhong An was too scared to answer. He just came up with an idea. Five taels of silver was too much.
Wang Yuan smiled and said: "This thing is very useful. It can be considered as buying off your technology."
Although Yang Shen, Du Jin and Bao Chaozhen were also surprised by Zhong An's changes, they did not think it was anything remarkable because there were no essential changes to the spinning wheel. The three of them are working closely together to create a
Spinning more than ten spinning wheels at the same time is a real qualitative leap!
Wang Yuan, on the other hand, is considering building a workshop. The work efficiency of two or three times is enough for him to make a small profit.
The reason why it is a small profit, not a big profit, is because this improvement is too simple. When the goods he sells cause market fluctuations, it will inevitably attract colleagues to secretly inquire, and it will 100% spread quickly.
What can really make a lot of money is the complex machine that Yang Shen, Du Jin and Bao Chaozhen are developing!
