In the palace of the king of Chu, Li Kuan was at home, and the small corn did not run out every day as usual.

However, this made the people in the palace miserable.

This little county lord brings a golden retriever everywhere every day to make trouble.

Today I went to the chicken farm and scared a bunch of hens half to death, tomorrow I came to the conservatory, I ruined the seeds that had just sprouted, and the day after tomorrow I made my brother who was only a few months old cry.

The new four evils of Chang'an City have become a major harm to the Chu Palace.

"Lord Wang, this little corn is getting more and more naughty, do you want her to go to Mengxue to study early?"

Cheng Jingwen had just coaxed her younger brother who was made to cry by Xiao Maize, and looked at Li Kuan a little helplessly.

"Mengxue basically doesn't go to school until after the age of six or seven, and Xiaomai is only three years old now, and I can't understand those things when I send them in."

Li Kuan naturally knows the magic of his daughter, and thinks it's not a matter of letting her toss like this all day long.

"She walks around with her golden retriever every day, and when she doesn't pay attention, she runs to Chang'an City to make trouble. This golden retriever weighs more than 200 pounds, and the guards who are waiting for leisure are not its opponents, and if it hurts someone outside, it will also be a trouble. ”

Li Kuan heard Cheng Jingwen say this, and thought about how to solve this problem.

Do you want to get the kindergarten out?

Specially train the children before entering Mongolian school.

Although at my age when I was a child, I was also wild everywhere, but even if it is a rural area, I will give you a three-year kindergarten for you.

This shows that kindergarten should have its meaning of existence, right?

"Jingwen, I see that you rarely go out of the house during this time, and I don't have time to be at home every day, will you feel bored?"

"It's not boring to be boring, that's basically how I've been since I was a child."

Cheng Jingwen didn't know why Li Kuan suddenly shifted the topic to herself.

"I have an idea, there must be a lot of noble children of Xiao Mai's age in Chang'an City. There will be no shortage of women who stay at home as often as you do. Is it possible to set up a special school to teach preschool children in Mongolia? ”

Li Kuan's idea is not earth-shattering, so Cheng Jingwen was not particularly surprised when she heard it.

"But Lord Wang, didn't you say those things that Mengxue learned, can't Xiaomai understand at this age? So what does this school for young children teach? These three or four-year-old children, even if you teach them things, it may not have any effect. ”

"The content of the kindergarten is definitely different from that of Mengxue. Rather than a school, this kindergarten is more like a place for children to gather together to play, enjoy group life, and impart some knowledge appropriately. ”

In Li Kuan's view, kindergarten is originally a place to impart teaching knowledge, and it is more about letting children develop some habits from an early age.

Of course, getting used to this thing actually means a lot.

The so-called three-year-old sees old, although this statement is a bit exaggerated, but it basically shows that the personality traits of childhood have a very huge impact on a person's life.

"If you say that, you can give it a try."

Cheng Jingwen felt that playing with a group of children seemed to be quite interesting.

"I asked Xu Jingzong to arrange it, and when the time comes, a kindergarten will be built next to the palace, and you can bring the snow geese and them to the kindergarten as teachers.

……

Watching the Shishan Academy, Li Kuan took a thin "book" and read it.

Since the advent of Datang Daily, newspapers are nothing new.

Xu Jingzong's special newspaper that has been brewing for a long time is finally coming out.

"Lord Wang, this is a newspaper sorted out after many screenings based on the teachings of various academies and the contributions of students, can you read it?"

Xu Jingzong wanted to start a different "newspaper", so it took a long time, and it was basically completed until now.

"The idea of this thing is very good, but it's not appropriate to call it a newspaper, and I think it's better to call it a magazine."

Li Kuan quickly flipped through the paper in his hand, but he was a little interested.

Obviously, what Xu Jingzong is going to launch is actually a magazine that publishes papers.

It's just that there are no papers in this year, and everyone's articles are different in form, and they can even be described as varied.

"Magazines? Our magazine is planned to be published once a month or half a month, which is really different from a newspaper. And I'm going to bind it into a book and sell it like a book. Lord, what is the name of this magazine of ours? ”

"Science!"

Li Kuan didn't think about it, and directly took the name.

There are hundreds of schools of thought, and now Confucianism is dominant, and he has come up with a new science to fight with it, and the eye-catching effect is definitely leveraged.

Besides, Li Kuan also hopes that the "Science" magazine of Guanshishan Academy can become the most authoritative and famous academic journal in Datang and even in the world.

Judging from the current situation, it is still worth looking forward to.

"Science?"

Although Xu Jingzong knew every word, he didn't understand what science meant.

"In the eyes of this king, science is an orderly system of knowledge based on testable explanations and predictions about the form, organization, etc., of objective things, and it is knowledge that has been systematized and formulated. The king has always emphasized that practice is the only criterion for testing truth, and this science is to organize our past practical knowledge into a set of theories and formulaic descriptions of the things that objectively exist around us. ”

Although he didn't understand, Xu Jingzong felt unclear.

"Lord Wang, then this "Science" magazine, the subordinates let the printing workshop start printing?"

It doesn't matter if you understand it or not, since Li Kuan has already said that the name of this thing is "Science", so be it.

Xu Jingzong would not be entangled with Li Kuan in this kind of matter.

"Huh? A new type of timekeeping mechanism? ”

Li Kuan was talking to Xu Jingzong while browsing the contents of the first issue of Science magazine.

Although most of the things in it are nothing new, it is a summary of some of the contents of the past academy lectures.

However, an article at the end of the magazine made Li Kuan interested.

How to calculate time is an old topic.

China is the first country in the world to know how to keep time. Around the end of the Shang Dynasty, there was a 100-quarter chronograph system that divided a day and night into 100 equal parts, and it was used in successive dynasties until the end of the Qing Dynasty.

Both sundials and leaky pots were once the most advanced timekeeping tools in the world.

However, in Li Kuan's eyes, the accuracy and convenience of these things have always been far from what he wanted.

It's not that he didn't think about making a watch or something, but thinking that there were so many precision gears and other parts in it, it was estimated that it would not be so difficult to make, so he gave up.

However, now that he saw this article, he felt that he might have reached a dead end.

Of course, Datang can't make such a thing as a watch now, but it doesn't mean that it can't make a bulky clock.

"What's going on with this Langqing?"

Li Kuan quickly skimmed the article, and there was actually a bit of real material.

Even in the article, he has sorted out the principle of this so-called new chronograph mechanism, and there is a model diagram.

"Lord Wang, are you talking about Langqing who wrote about 'a new type of timing mechanism'? This person I know, is a student of Gewu Academy, is the son of a craftsman in the printing workshop, has been studying in the academy for three years, is very talented in the production of various machinery, the Tang Dynasty Royal Qian Zhuang punching silver coin machinery, is he involved in the improvement. ”

Xu Jingzong has read every article selected this time.

Although some of the content may not be very well understood, he has learned about the author's situation.

To a certain extent, people like Xu Jingzong are still very easy to use as leaders.

Li Kuan feels this way now.

Basically, things related to Guanshishan Academy, you can basically get the answer by asking Xu Jingzong.

"Call him here, and the king will see him."

The time of day and night is different throughout the year, and it is actually very inconvenient to not have an accurate timekeeping mechanism.

Li Kuan is ready to see how far this Lang Qing has studied this thing, and if he can, then get the clock out as soon as possible.

Anyway, I didn't think about it in one step, and I planted it in a big way first, which should be very marketable.

"The student has seen His Royal Highness the King of Chu!"

Soon, someone came to Li Kuan with Lang Qing.

This is a young man who looks a little wooden, with dark skin and is not tall, but his eyes are very energetic.

"Come, sit down."

Li Kuan showed a relaxed smile.

Successful superiors tend to be very kind when facing the bottom of the hierarchy.

On the contrary, when facing direct subordinates, they may give severe criticism or accusations.

Li Kuan is already very proficient in this set.

"His Royal Highness the King of Chu, I ...... I'll just stand. ”

For Langqing, standing may be less stressful than sitting.

Li Kuan didn't force him.

"When did you start researching this new type of timing mechanism?"

"There is a sundial in a Taoist temple near my house, and I have often visited this temple since I was a child, and I am very interested in this sundial that can indicate the time. However, because the sundial uses the shadow of the sun to keep time, it is useless when it is cloudy or rainy. So I've always had a dream to make something that can be timed automatically. Because I'm a carpenter myself, I'm also good at carpentry, and I've tried to make some things, but I've never succeeded. ”

When it comes to the things he researches, Mu Ne's Lang Qing can't see Mu Ne's appearance at all.

"Until one time, when His Royal Highness the King of Chu came to the academy to explain the gears, bearings and bolts to everyone, I suddenly thought, can I use these things to make a new type of timing mechanism?"

When Li Kuan heard this, he glanced at Lang Qing more.

When I went to the academy to talk about basic industrial parts such as gears, I didn't go for clocks, but I didn't expect to receive an unexpected joy now.

"Your idea is very good, this timing mechanism to accurately record the time, must have parts to rotate or move constantly, but also need some transmission mechanisms. As long as it comes to rotation and transmission, bearings and gears are basically unavoidable. ”

Although Li Kuan doesn't understand how watches are made, he still knows some about the general structure and principles of mechanical watches.

If it weren't for the fact that he didn't see a clock in the system that could be exchanged, he would have wanted to directly get a sample to Langqing and let him copy it directly.

Now I have to discuss with Langqing and implement this new timing mechanism that is still on paper into reality.

"That's right, His Royal Highness the King of Chu, the students think so too. So after that, I went to the Bearing Research Institute to participate in the development and production of bearings, and also designed several gears together. Then I thought about how I could use these things to do the timekeeping function. ”

Xu Jingzong was also surprised to watch Li Kuan and Lang Qing happily exchange the so-called new timing mechanism.

He didn't pay much attention to this article, so although he thought it was a little interesting, he also put it at the back of Science magazine.

Now it seems that this first issue of the magazine seems to be the last article that attracts Li Kuan's attention the most.

So the king had an idea that there were twelve hours in a day, and that each hour had eight quarters of an hour, which seemed too coarse. We can divide these twelve hours into twenty-four hours, twelve hours during the day and twelve hours at night. Each hour is further divided into sixty minutes, sixty seconds per minute. In this way, a quarter of an hour is equivalent to fifteen minutes, and the accuracy of this timing mechanism has been improved by leaps and bounds. ”

Li Kuan said as he found a piece of paper and pen next to him and drew the most common dials of clocks.

At the same time, he also communicated the working principle of the clock with Langqing.

Although Li Kuan's words were a bit messy, Lang Qing was always able to grasp the key point of the problem at a critical moment.

It seems that he must have really studied this clock in depth.

Li Kuan couldn't help but have a trace of expectation in his heart.

"His Royal Highness the King of Chu, I think your setting is completely feasible, my thinking has been a little vague before, but now when I hear you say this, I think it is clear all of a sudden. I'm confident that I'll be able to produce a sample this month. ”

Lang Qing suppressed the excitement in his heart and took the initiative to make a promise to Li Kuan.

"Well, you can talk to the craftsmen at the ironworks to see if their latest steel plates can meet your requirements. When the four-wheeled carriage was made before, they should have accumulated a lot of experience in this area during the development of springs. ”

These days, it's a bit difficult to get a battery.

No matter what type of clock it is, there must be something to power it.

Therefore, when Li Kuan communicated with Langqing just now, he directly proposed the use of clockwork and pendulum clock as the power source of clocks.

This is also how some old-fashioned pendulum clocks work.
