- Many people don¡¯t know that the theory of isochrony was actually discovered by Galileo when he was seventeen years old.
So a saint is a saint. A seventeen-year-old handsome scholar only thinks about how to get out of singles. How can he have such a high level of thinking?
But it is a pity that it was not until seventy or eighty years later that the Dutch scientist Huygens used the "isochrony theory" to make a pendulum.
Once the pendulum is made, it will be easy for a pendulum clock to appear - you can see on TV that the pendulum clocks and standing clocks in the homes of wealthy people in the forty or fifty years before the founding of the People's Republic of China were of this model.
Then more than ten years later, Huygens invented another key to "miniaturizing the pendulum clock" - the hairspring, which completely solved the problem of the escapement speed regulation system, allowing the balance wheel and speed needle to work simultaneously. Function without getting in the way.
The hairspring is actually very simple. Just think of it as the pendulum in a pocket watch.
To put it simply, the escapement speed regulating system actually moves the hour hand and minute hand together with the second hand, but the moving speed is very slow, so to the naked eye, only the second hand keeps moving.
If there is no hairspring for speed regulation, the three needles cannot be coordinated, and naturally there will be no coordinated advancement function of the clock.
Except for the tourbillon invented by the "watch saint" in the 18th century, which opened the prelude to mechanical watches, no one has made more contributions to clocks and watches than Huygens.
Of course, Liu Mingqi still understands things like tourbillons.
It¡¯s just the same process as the pendulum, hairspring, speed needle, prime mover system, transmission system, etc. It sounds simple, but to actually do it, conservatively it can be completed in one or two years, and it is not uncommon in three to five years.
But these are no longer Liu Mingqi¡¯s business. He is going to leave it to the skilled craftsmen of Dakang to study.
Anyway, I will tell you the theory, drawings and detailed principles, just go and think about it.
I¡¯m used to sitting back and enjoying the results.
As for why Liu Mingqi wants to make clocks now, naturally the first one is for future scientific research, recording data, etc., and the other part is because when sailing, a clock is needed to determine the time.
During a great voyage, any accident may happen. In addition to ships, cannons, compasses and other things, this clock is also very important.
In the past few days, the young man has been busy with this matter.
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 have a look.
¡¡
After getting on the new carriage that was exclusively for Wu Yeshuang, Su Xiaoxue looked at the bright lights outside through the glass window, and suddenly felt an unreal feeling.
"Sister Shuang~~"
"Um?"
"Your Liu Mingqi is not a monster, right?"
"Um!?"
"Oh, don't look at me like that, don't you think it's weird?" Su Xiaoxue asked, tilting her head, "He doesn't act like a person at all It's like he's possessed by a ghost. the same!"
"Bah!"
Wu Yeshuang rolled her eyes in a rare move, "If you say he is possessed by a spirit, maybe more people will believe it."
"It's all the same. Anyway, I think he is simply not a human being!" Su Xiaoxue said, "He has changed the life we ??have been accustomed to for thousands of years, whether it is "Encouraging Learning", "Bringing In Wine", "Teacher's Talk", "Jin Se", magic medicine, soap, sugar, honeycomb briquettes, wooden handle grenades, hot air balloons, oiletc., others have achieved great things in one aspect, but he is all-powerfulSister Shuang, you Do you think it¡¯s possible?¡±
"Why is it impossible?" Wu Yeshuang asked her, "The facts have already appeared in front of us, isn't it true?"
"But¡¡"
"There's nothing to be ashamed of. You're just trying to get into trouble." Wu Yeshuang interrupted Su Xiaoxue's words, "Let me ask you one question, is Ming Qi a bad person or a good person?"
"Good guy."
Su Xiaoxue said without even thinking about it.
If the people who provide briquettes to the people for almost free are not good people, then there are no good people.
"If a war could have been avoided, but those who participated in it at all costs, and even prepared to die for the country's death, are not good people, then there will be even less good people.
"That's right, then why are you still thinking so much? Anyway, he is a good person and is on our side." Wu Yeshuang said slowly, "As for whether he is possessed by a god or a drowned man,Yes, they can push it back directly.
???????????????????????? After they endured hardship, the emperor still wouldn¡¯t support them. Without a backer, they have never been arrogant since then.
If Liu Minghua is sued by Wu Yeshuang to the imperial government office, he will have a lot of fun!
That¡¯s why he hurriedly revealed his identity.
After confirming that it was him, Wu Yeshuang and Su Xiaoxue walked out.
"Gong Lu, do you have something to do with Xiaoxue?" Wu Yeshuang asked.
"Yes."
Liu Minghua smiled, cupped his hands and said, "I have heard that Miss Su likes to talk about classics and Taoism, as well as poetry and poetry. It just so happens that a group of literati from our capital will have a gathering at Yongyue Tower tomorrow, and I specially invited Miss Su to attend. , everyone is lively and lively, get to know more like-minded friends!¡±
After finishing speaking, he looked at the pretty and innocent Su Xiaoxue expectantly.
After a lot of planning, he created such a party just to have more contact with Su Xiaoxue, so as to have a chance to break the beauty's heart.
If it was a month ago, Su Xiaoxue would definitely be willing to attend such a party. She is not pedantic in nature and likes such elegant yet lively gatherings.
But after experiencing so many days and seeing so many dazzling inventions around Liu Mingqi, Su Xiaoxue's interest in this so-called gathering of talented men and beauties suddenly dropped.
In addition, she had already decided to go see the cows with Liu Mingqi tomorrow morning, so it was even more impossible to agree.
So Su Xiaoxue said crisply: "Thanks to Duke Lu's kindness, I have something to do tomorrow, so I have to apologize!"
With that said, she turned around and walked into the Witch Mansion.
Liu Minghua was stunned and wanted to reach out to stop her, but immediately put down his arm.
Don¡¯t be abrupt or leave a bad impression on her!
Liu Minghua thought silently in his heart, and then watched Su Xiaoxue walk in.
Wu Yeshuang looked at him strangely.
Is this Lord Lu a fool?
I really don¡¯t know what he is thinking?
Although I know that he and Mingqi are not dealing with each other, what do you mean by coming to see Su Xiaoxue now?
Don¡¯t you know that the Queen Mother is actively working as a matchmaker between Liu Mingqi and Su Xiaoxue?
Even now, the two of them have not succeeded, but before the Queen Mother said she gave up, who dared to come in contact with Su Xiaoxue, and who dared to have such involvement with her?
¡°You rush over now and say that you want to invite Su Xiaoxue to the party. Isn¡¯t this a slap in the face of the Queen Mother in public?
Don¡¯t rely on the fact that you are also the grandson of the Queen Mother!
There is a big difference between grandson and grandson! !
