I am the king of the dead

A mechanical timepiece with precise timekeeping.

Chapter 435 This uncle is obviously super strong, but he is overly cautious

Zhu Qiyu came to Chen Youde's hydraulic workshop, where the silversmiths were minting silver coins in full swing.

And Chen Youde was swinging a big clock with a height of one person. After the clock was made, it would be sent to various turrets, and it would be used as a time teller, so that the people could keep time in daily life.

To Zhu Qiyu's slight disappointment, it is still a water clock, similar to a hydrometer, but it is still limited to water power, and it is not very accurate.

Like the one on Zhu Qiyu's desk, Qin Tianjian has to check the time every day at noon.

This thing is enough to keep time on weekdays, but it is still too big to be used to measure longitude and latitude, or as a standard clock.

"See Your Majesty, is Your Majesty honored?" Chen Youde led a group of silversmiths to salute.

"Is this the clock you want to present?" Zhu Qiyu looked at the clock and asked slightly disappointed.

Chen Youde shook his head and said: "Your Majesty, this is not a clock that I want to donate. It is just a very ordinary clock that is sent to various workshops to tell the time."

"What I want to present is this pendulum clock."

Chen Youde picked up an ornament from the person next to him, and said very confidently: "Your Majesty, please take a look."

A ball was hung up, Chen Youde pulled it up in the air, and then let go, the ball was swinging randomly in the air, because the thread was thin enough, the swinging time was relatively long.

But Zhu Qiyu still didn't understand what Chen Youde wanted to express.

Chen Youde said with a smile: "I have been observing and found that the time for the ball to swing is the same. It has nothing to do with the weight, but only with the length of the string."

"It's amazing, but it's true. Ulugh Beg's discourse also supports Chen's idea. He also discovered this magical swinging phenomenon."

"That is, as long as the lines are the same length, the swinging time is also the same, so he can calculate the precession accurately."

The good man Ulugh Beg always provided Zhu Qiyu with many surprises. Zhu Qiyu understood what Chen Youde said. This is the isochronism of the pendulum, which only depends on the square root of the length of the cycloid and the acceleration of gravity.

Ulugh Beg is a genius in astronomy and arithmetic. There is no doubt that he can accurately calculate the precession, and it is definitely not a fabrication.

Zhu Qiyu nodded and said, "You continue."

Chen Youde said: "This is a very common counter. Every time it is dialed, it counts once."

He put a very ordinary counter on the pendulum position.

"Like this, every swing, you can count, so we get a precise timing."

"When our pendulum is heavy enough, the counting effect becomes negligible."

"I'm here, I just want to explain the principle clearly, and I dare not deceive Your Majesty."

Zhu Qiyu nodded and said: "I can understand you, the principle is very clear."

Chen Youde used the isochronism principle of the pendulum to carry out precise timing, which is exactly the same as Ulugh Beg.

The pursuit of precise timing is tireless.

Ulugh Beg also used this timing method to accurately calculate the precession and the inclination of the Earth's axis.

Chen Youde continued: "Your Majesty, there are twenty hours on the water auspicious platform, and Su Song divides each hour into Shichu Shizheng."

"On the water transport observatory, the second floor is the wheel for the beginning of day and night, and there are 24 wooden figures beside the wheel, which represent the beginning and time of the twelve hours."

"The third layer is the engraved Sichen wheel. There are 96 Sichen himself beside the wheel, and one person appears every moment."

"So the three quarters of the noon in the usual sense should be the three quarters of the morning."

"So?" Zhu Qiyu continued to walk forward and asked.

Chen Youde bowed his head and said: "There are twelve hours in a day, 24 hours, 96 quarters, and each quarter has fifteen omissions (minutes), so each hour has sixty minutes, and each minute has sixty degrees and seconds. There are [-] seconds in a day."

"It's the so-called: the sun and the moon are bright and day and night are divided, and those who miss the pendulum clock are accurate, and there is no minute or second."

Zhu Qiyu understood that Su Song in the Northern Song Dynasty had divided a day into 24 hours and 96 quarters for more accurate timekeeping. Each hour was divided into 1 minutes, and each minute was divided into 60 seconds.

Sixty This is the algorithm of the heavenly stems and earthly branches.

"I tried out the calculation length of each degree second, and made a pendulum clock." Chen Youde said with a smile: "Your Majesty, please have a look."

Chen Youde took the emperor to a very solemn room, and pulled a red silk mask away.

Zhu Qiyu looked at the one-person-tall clock, and heard the familiar clicking sound of the clock.

That was the sound of the pallet fork of the pendulum clock escapement hitting the escape wheel.

There is a long pendulum under the clock, which is constantly swinging. There are four layers of purple sandalwood on the watch head, showing numbers.

The principle is very simple, just like the math teacher is always teaching 1+1, but during the exam, the questions will become extremely complicated.

Chen Youde said it simply, but the mechanical escapement mechanism is very complicated.

Chen Youde pointed to the four layers of scale above and said: "Your Majesty, the first layer is for hours, and there are 24 in total. The second layer is for engravings. For the convenience of calculation, there are only four quarters, and each hour is reset once. The third layer is for minutes, and there are ten in total. Five points, the fourth layer is seconds, a total of 60 seconds."

"Each swing is one second."

Zhu Qiyu looked at it for a long time, and was very satisfied with this pendulum clock. He nodded and said: "Four quarters, each quarter is 15 minutes, that is to say, there are six and 10 minutes in an hour, right? If you omit the quarters, 60 seconds is one hour." Sixty minutes is an hour."

Chen Youde frowned and thought for a long time and said, "Your Majesty is wise."

Remove the engraving, and divide the time into days, hours, minutes, and degrees.In this way, the timing can be more accurate, but the quarter does not disappear.

Zhu Qiyu looked at the pendulum, and then at the clock.

Zhu Qiyu said with a smile: "It's already very accurate, but I hope it can be more accurate."

"Send a clock to Qin Tianjian, and make persistent efforts to make it more accurate."

This clock is actually related to the local acceleration. It will slow down in low latitude areas and needs to be adjusted.

If it is sent from Beijing to Nanya, the clock will slow down by 15 minutes, and it cannot be used as a longitude clock.

Don't worry, just take your time, it's much more accurate than before, at least it's back to the point where it was as accurate as counting seconds in the Northern Song Dynasty.

This is already huge progress.

Xing'an followed His Majesty back to the lecture hall, he held a copy of the mansion newspaper and said hesitantly: "Your Majesty, is it the Wan Yan Shu or His Highness's Theory of Sharp Handle on the front page?"

"Let me think slowly." On the left hand of Zhu Qiyu's hand is the Wanyan book, and on the right is the theory of weight and severity, no matter which one Zhu Qiyu is very fond of.

The Wanyanshu is an adjustment to past policies, summarizing the pros and cons, and then making targeted adjustments. This matter has never been done since Xie Jin’s Wanyanshu, just as no official has been appointed. same salary.

The theory of the importance of sharp handles is not a comprehensive review of Guan Zhong's theory of importance, but another theory of sharp handles that is more in line with the Ming Dynasty.

There are priorities and priorities.

For example, in the Gong City of Xuanfu, there is a specific application of the theory of weight and weight. Steel arrows and fire feathers are all heavy objects, and smugglers chop them up. Iron pots, salt, tea leaves, etc. are light objects and can be traded.

This is the same reasoning in Shibo Division.

For example, innovations in supply and demand side reforms to adjust prices, such as Sancheng can effectively adjust prices, which surprised Zhu Qiyu.

Last time in Nanya, Zhu Qiyu prepared [-] million catties of coal to fry, but in fact the quantity was too much, Zhu Qiyu finally began to half sell and half give away, all of which were given to the people.

"This uncle is obviously super strong, but he is overly cautious"

Zhu Zhanqian's ability is very strong. Judging from the methodical way he has supervised the country several times, his ability is worthy of recognition, but he is very cautious.

In fact, it is normal.

Because the whole family of Hanwang Mansion was in trouble.

Zhu Zhanqian watched his uncle, the king of the Han Dynasty Zhu Gaoxu, being roasted to death with his own eyes, and the shadow in his heart was already very heavy.

Empress Dowager Sun never dared to offend Zhu Qiyu completely. Empress Dowager Sun knew that when Zhu Qiyu ascended to the throne, even if he was a concubine emperor, he would still be an emperor.

As the emperor, his power will be infinitely great, so the lives of the whole family of Ji Wangfu are all in the emperor's mind.

Therefore, Empress Dowager Sun retreated step by step, even when Sun Zhong and Sun Jizong were beheaded, Empress Dowager Sun did not say a word.

In life, there are many choices.

"Xing'an, which one do you think will be the headline?" Zhu Qiyu thinks that either of these two can be the headline, but there is only one headline.

Xing'an thought for a while and said: "The theory of the importance of the power of the emperor is still not as important as the Wan Yan Shu. After all, it is the basis of state affairs, and the theory of the importance of power is still in the stage of exploration."

Zhu Qiyu thought for a long time, nodded and said: "You point two first merit cards to Uncle Huang and Luo Changshi."

Luo Bingzhong found the basis and source for Zhu Zhanqin's theory, which also perfected Zhu Zhanqin's theory.

The headline on the front page of the mansion newspaper once again brushed shoulders with Uncle Fat Emperor.

The pendulum clocks for precise timing were also sent to various government offices. As long as one was sent to Nanya, it would be found that the pendulum clock needed to be adjusted. It would not be too late for this kind of improvement.

Zhu Qiyu began to deal with official documents day after day, and it was not until the willows on the moon and the lanterns first came on that Zhu Qiyu put down the memorials in his hands.

Ran Siniang carried two small wooden buckets to refill the water clock on the table.

Xing'an always used various opportunities to let His Majesty and Ran Siniang get in touch more. His Majesty took care of everything and forgot about this girl in a few days.

"Come?" Zhu Qiyu said with a smile.

Ran Siniang didn't answer, and started adding oil to the lamp.

"What's wrong?" Zhu Qiyu asked with a smile, is this Tiankui coming?

Ran Siniang sighed and said: "Empress Wang asked my concubine to check on His Majesty's condition more, don't get too tired, the words are beyond words, just to let His Majesty return to Tai'an Palace as soon as possible, Li Guiren is not pregnant yet."

Indeed, Zhu Qiyu got busy, and it was already late when he went back, so he usually just went to rest.

Li Xi'er had never been pregnant, so she was a little anxious, so she naturally wanted to complain to Queen Wang.

"Did you say something nasty?" Zhu Qiyu thought that Queen Wang had taught Ran Siniang a lesson.

In this situation, Empress Wang could easily misunderstand Ran Siniang and Zhu Qiyu. They stayed in the martial arts hall and got along day and night. You love me deeply. When women get jealous, how can they talk about so many reasons?

Competing for favor, this kind of thing is inevitable in the harem.

Ran Siniang shook her head and said: "Queen Wang was very angry, she didn't blame the concubine too much, but Queen Wang asked the concubine to persuade Your Majesty more."

"The concubine's identity and name are not right, how can I persuade her? I'm caught in the middle, and I'm in a dilemma."

Zhu Qiyu could hear some resentment towards marriage.

This is actually not a hate marriage. Ran Siniang is still sorting out the Miao medicine in the southwest and the medicine in the Central Plains, removing the chaff and saving the essence, and finally integrating it into "Health Prescription". This process takes a long time. Before she finishes, she cannot marry .

Ran Siniang broadened her shoulders for Zhu Qiyu, and said with a smile: "Empress Wang is very worried that your majesty will be exhausted. Sitting for a long time will lead to illness. My concubine said that your majesty goes through the Beijing camp every day. It's not just sitting still. So many things."

"But Queen Wang is still very worried about Your Majesty."

"very nice."

This sentence is really good. Naturally, Ran Siniang envied Zhu Qiyu and Queen Wang for raising their eyebrows together, and also envied Queen Wang for caring about Zhu Qiyu openly.

Zhu Qiyu grabbed Ran Siniang's hand and said, "When will you finish your work?"

"I don't know." Ran Siniang stopped to broaden Zhu Qiyu's shoulders, and said slightly melancholy.

She really doesn't know where the end of medicine is, she is already working hard to learn the medical skills of the hospital.

Zhu Qiyu thought for a while and said: "You can enter the palace first and then continue to practice medicine."

Of course Ran Siniang thought about this possibility, but shook her head: "There is a female doctor in the imperial hospital who is already deviant. If she enters the palace and still sits in the imperial hospital, I am afraid that the officer Feng Xian will start chattering again."

"Your Majesty has a lot to do every day, and there are already many troubles. I will not add trouble to Your Majesty."

Zhu Qiyu raised his tone a little and said: "Am I afraid of them? Speaking of these Fengxian officials, I get angry, and I wish I could dismiss them all!"

"I said subsidy, how good is that?"

"After Wang Zhi let the wind out, they were all discussed. It turned out that they were lucky, and when they were used, they couldn't even make up nonsense!"

There are no secrets in the Fengtian Temple, and the things discussed in the Fengtian Temple are everywhere at noon.

Ran Siniang naturally also heard about the debate in the court today.

Originally, hello, me, everyone, good things, the gang of sharp-tongued guys in the Metropolitan Procuratorate couldn't make up the wrong reasoning, so the emperor couldn't let the emperor make up the wrong reasoning.

The emperor couldn't hold back anymore, and it was useless to scold them directly.

"Your Majesty is not afraid of them, but I am." Ran Siniang said with a smile.

Zhu Qiyu pulled Ran Siniang and pulled her into his arms.

"Hey...Your Majesty." Ran Siniang didn't expect it at all, she sat on Zhu Qiyu's body, and her whole body trembled, but Ran Siniang still hugged Zhu Qiyu's neck with both hands.

The reason why Ran Siniang is holding her like this is because she is sitting like this. If she doesn't hold her, she will be unstable and fall easily.

The hood is a little in the way.
