Many people don’t know that the theory of isochronicity was discovered by Galileo when he was seventeen years old.

So a saint is a saint. A handsome scholar who is seventeen years old this year is just thinking about how to get out of singleness. How can he have such a high level of thinking?

But unfortunately, it was not until seventy or eighty years later that Dutch scientist Huygens used the "isochronic theory" to create a pendulum.

Once the pendulum is made, the pendulum clock will easily appear on TV. In the forty or fifty years before the founding of the People's Republic of China, the pendulum clocks and standing clocks in the homes of wealthy families were in this mode.

Then more than ten years later, Huygens invented another key gosspring for "minimizing the pendulum clock", which completely solved the problem of escapement and speed regulation system, so that the balance wheel and fast and slow needle can operate at the same time without hindering.

The thing about gosspring is actually very simple. Just think of it as the pendulum inside the pocket watch.

Simply speaking, the escapement speed control system is actually moving with the second hand, but the movement speed is particularly slow, so to the naked eye, it is only the second hand that is always moving.

If there is no hairspring for speed regulation, the three-pin will not be coordinated, and naturally there will be no coordinated function of the clock.

Except for the tourbillon, a divine object invented by the "Watch Saint" in the 18th century, which opened the prelude to mechanical watches, no one has more than Huigens's contribution to the clock.

Of course, Liu Mingqi still knows the tourbillon.

It's just like the pendulum, gosspring, fast and slow needle, prime mover system, transmission system and other processes, it sounds simple, but if you really want to do it, it's more conservative to say that it can be completed in one or two years, but three or five years is not uncommon.

But these are no longer Liu Mingqi's affairs, and he is going to leave them to Dakang's skilled craftsmen to study.

Anyway, I will tell you the theory, drawings and detailed principles, just think about it.

I am used to sitting and enjoying the fruits.

As for why Liu Mingqi wants to make watches now, the first one is for future scientific research, recording data, etc., and the other part is because when sailing, clocks are needed to determine the time.

During the voyage, any accident may occur. In addition to ships, cannons, compass and other things, this clock is also very important.

The boy has been busy with this matter these days.

He has drawn hundreds of drawings and written dozens of pages of concepts and principles.

It was during this process that Wu Yeshuang discovered it, and then Wu Yeshuang brought Su Xiaoxue to take a look.

...

Sitting on the new carriage dedicated to Wu Yeshuang, Su Xiaoxue looked at the bright lights outside through the glass window, and suddenly felt an unreal feeling.

"Sister Frost"

"Um?"

"Your Liu Mingqi is not a monster, right?"

"Um!?"

"Oh, don't look at me with such eyes. Don't you find it strange?" Su Xiaoxue asked with her head tilted, "He acted like a person at all...it was like, like a ghost possessed!"

"Pooh!"

Wu Yeshuang rolled her eyes rarely, "If you say he is possessed by a god, maybe there are more people who believe it."

"It's all the same. I think he's simply not a human being anyway!" Su Xiaoxue said, "He has changed the life we ​​have been used to for thousands of years. Whether it's "Encouraging Learning", "Wine in the Wine", "Talents' Talk", "Jinse", or magical medicine, soap, sugar, honeycomb coal, wooden grenade, hot air balloon, oil... etc., it's amazing that others have achieved in one aspect, but he's omnipotent... Sister Frost, do you think it's possible?"

"Why is it impossible?" Wu Yeshuang asked her back: "The facts have already appeared in front of us. Isn't it true?"

"But……"

"Nothing is true, you're just a stubborn person." Wu Yeshuang interrupted Su Xiaoxue's words, "I'll ask you one thing, is Mingqi a bad person or a good person?"

"Good guy."

Su Xiaoxue said without thinking.

If the people who provide honeycomb coal to the common people almost for free are not good people, then there will be no good people.

If the people who could have avoided war but participated in it desperately, and even prepared to be a good person for the country's death, there would be no good person.

"Well, why do you want to do so much? Anyway, he is a good person, from our side." Wu Yeshuang said slowly, "As for whether he is possessed by a god or suddenly enlightened after drowning, what does it matter?"

"Um……"

Su Xiaoxue nodded slowly.

If you say that, it makes sense.

You really can't verify this kind of thing.

Liu Mingqi said that she is not a god, you think he is lying.

Liu Mingqi admits that she is a god, and you will not believe it even more.

So what do you think of those who have nothing to do?

After letting go of this matter for the time being, Su Xiaoxue continued to ask, "But why have you been creating opportunities recently to let me meet him? Do you want me to marry him too?"

"Won't."

Wu Yeshuang shook her head: "I am a person who is indifferent by nature, but I will not be so generous that I give up my man."

"Why is that?"

"Because I saw a shadow of someone in you..." Wu Yeshuang stared at her, "You all have innocent hearts, and are full of exploration and curiosity about the unknown. But she is not as good as you, so I don't want you to miss such a wonderful world and such a wonderful era like her."

"Who is she?" Su Xiaoxue said curiously.

"Unsible."

"Let's forget it." Su Xiaoxue gave her a blank look and said, "Then the great era you think will be developed in Liu Mingqi's hands?"

"Do you think it's not?" Wu Yeshuang asked back.

Su Xiaoxue had nothing to say to refute.

She just nodded.

Just the contacts of these few days made her feel that Liu Mingqi had endless novel and fun things around her.

No, it's not fun.

But practical and interesting.

The carriage is one, another pocket watch he is making tonight, and it is even more practical.

And that kind of barbecue...

He invented the hotpot that Dakang eats in winter now.

It seems that I can’t live without fun when I stay with such a person!

But I don’t like him. I can be his assistant and participate without being misunderstood!

Seeing Su Xiaoxue's heartbroken look, Wu Yeshuang said: "Mingqi will go outside the city tomorrow and see his cows. Do you want to go?"

"dairy cow?"

Su Xiaoxue woke up immediately. Liu Mingqi was also the largest milk merchant in the world.

The dignitaries and nobles in the capital, including the emperor, were drinking milk produced in his pasture.

The most authentic milk tea sold in the capital must be the milk produced in his ranch.

Su Xiaoxue is also a milk lover, but she has never seen a professional cow, so she soon became interested.

"I'll go!" She pointed Fan Zhen lightly, then asked, "Where are you?"

"I'm going to do an experiment tomorrow, so I won't go!" Wu Yeshuang said, "I'll ask them to pick you up at that time... won't you be afraid, are you?"

"I'm afraid he'll eat me?"

Su Xiaoxue said disdainfully.

She also believes in Liu Mingqi's character very much.

It is said that this Prince Yu is still a boy now, which is incredible!

If it weren't for the fact that there were so many beautiful wives around him who were about to enter the house, she would have thought that Liu Mingqi would like the second master of Tu!

Since it is not a habit of breaking sleeves, it can only prove one thing. The reason why this saint is a saint is really a model for strict self-requiring!

...

In my mind, the carriage arrived at the witch's mansion without realizing it.

Su Xiaoxue lives in the Wu Mansion as long as she is in Beijing, which is why she and Wu Yeshuang are so close.

As a result, the carriage had just arrived at the door, and a group of people rushed out next to it. The leader shouted loudly: "Miss Su! Miss Su!"

Wu Yeshuang was shocked. She hadn't moved any more. The old slave who was guarding the door immediately blocked the carriage with a stick: "Who is not open? This is the Minister of Works' Mansion! If you don't get out of here, I'm called the city patrol constable!"

"No, no!"

The leader shook his hand and said loudly to the carriage: "Miss Wu, is Miss Su inside? I am Liu Minghua from Prince Li's Mansion, and I have no malice!"

As mentioned earlier, the reputation of the royal family in the Gyeonggi area is not bad.

Most of the reason is that the past prefects of the imperial capital were important officials of the Legalists. They do not care about your family members, but they will be arrested if they are guilty. Sometimes when they encounter a weak Zongzheng, they can take it back directly.

But after they endured hardships, the emperor would not support them. Without a backer, they were never arrogant ever since.

If Liu Minghua was sued by Wu Yeshuang to the Imperial Palace, then he would be very happy!
