Great Song

This essay has nothing to do with chime clocks, it's just about pendulums.Firstly, he expounded the principle that no matter the length of the pendulum, the swinging time is the same, so it can be used for timing, and then he talked about his own discovery.

It turned out that this person took the pendulum down to test the principle of swing. In order to make the pendulum more unconstrained, he made a universal joint at the top of the rope, so that the pendulum was no longer controlled by the direction.Then push the pendulum again, and its trajectory will be shifted.But shouldn't the pendulum only swing from side to side? Why is there such a weird phenomenon?

The person who wrote the article did not explain clearly the reason for this phenomenon.He also said that the pendulum in his hand was too short, and it would stop after shaking for a while, so it was impossible to continue observing.At the end of the article, he stated that if someone can make a pendulum as high as [-] feet, and attach a heavier pendulum, he might be able to find out the truth.

This is not what the famous Meng Xisheng said, but an unknown person who has never seen it before.Logically speaking, this essay should not attract the attention of others.However, the self-ringing bell has become all the rage in Tokyo recently, and Han's shop is crowded every day, so the things in this article have naturally become the talk of people with troublesome things after dinner.

"Did you see the pendulum that was mentioned in the newspaper today? There is a carpenter next door to me, and they all messed around with it. Hey, don't mention it, you really have some skills!" An idler said happily .

"What else can the carpenter come up with? Is it possible that he also wants to publish an article in "Ri Xin Bao?" The tea drinker almost burst out laughing.

"Don't say it, it doesn't matter whether this article makes sense or not. That twenty-foot pendulum makes people fascinated just thinking about it!" Regardless of the two bars, another table also interjected, "It's so high, even if you think about it!" It’s almost the same as the Iron Tower, right? If it’s such a big chiming bell, maybe the whole city of Tokyo can hear it ringing!”

"Wait, nobody mentioned clocks in the papers? Didn't they just talk about pendulums?"

"Having made such a big pendulum, are you afraid that you won't be able to make a clock?" Hearing the retort, the person said indifferently, "If you can make it, it will definitely be a sensation in the capital!"

"you do not say!"

These words caused everyone in the teahouse to nod repeatedly.The twenty-foot clock is magnificent when you think about it!

"I heard that the "Ri Xin Bao" has something to do with the Han family. Could it be that the Han family is planning to build such a big pendulum?" Someone asked curiously.

"I think it's the same! Where else in Tokyo City can have such a grand scene?" The man next to him clapped his hands and praised.

A group of people chatted with great interest, and they all thought to themselves that they would have to chat with their wives and children when they got home.As a result, the news about the "twenty-foot pendulum" spread more and more widely. I don't know how many people are looking forward to seeing the real thing.

Unexpectedly, half a month after the rumors spread, there was still no movement in Han's shop, but there was a copper drain shop in the east of the city, and it started to publicize it with great fanfare.It is said that they will build such a huge pendulum in Daxiangguo Temple to demonstrate the weird trajectory mentioned in the newspaper.

Now the world is in an uproar.But who cares so much?One by one excitedly ran to Daxiangguo Temple to watch, only hoping that the high platform erected would be completed as soon as possible.

"I thought Jingsheng was going to build this pendulum, but I never thought that another family would take over the job." Hearing the news, Su Song came to look for Han Miao.

When publishing the short article anonymously in the newspaper, Su Song thought that Han Miao wanted to build the pendulum by himself for publicity, but someone else snatched it.But looking back, it's not a bad thing.After all, the purpose of hanging the pendulum is to verify the rotation of the earth, and it would be safer to leave it to others.It's just that even he didn't expect it to be so smooth.

"Nowadays, there are quite a few merchants who want to imitate the chiming clock. What could be more gimmick than this?" Han Miao smiled slightly, not feeling surprised at all.

No one will be left behind when it comes to being in the limelight.Especially with such a large landscape, it is even more eye-catching than the lanterns on the Lantern Festival.If it can be made, the store's reputation will be spread, and it may be able to compete with the Han family's chiming bell in the future.

Hearing this, Su Song was even more emotional: "In this way, wouldn't it be possible to be robbed of the business. Jing Sheng is really willing..."

This is also what Su Song admires the most.Han Miao gave him a lot of money when he was studying the chiming clock.Su Song got a little burnt with this money.Although it is cost-effective to forge some of the structures in the chime clock with a water forging hammer, it is not difficult for skilled craftsmen to imitate them.It can be said that once this thing comes out, it is bound to be imitated.Wouldn't Han Miao lose money by giving him so much money?

As a result, Han Miao didn't seem to care about money at all. As soon as the chiming clock was released, he published an article in the newspaper, which made people gain momentum.In this way, how can those businessmen who intend to make imitations miss the opportunity?It's not about scrambling to build this huge "pendulum".Although their plan was implemented, Han Miao undoubtedly missed a good opportunity to make money.

Han Miao smiled and shook his head: "If you are afraid of being imitated, you don't need to do business. If you want to stand firm, you still have to rely on your own ability. In this case, why don't you handle things smoothly, and it will solve your knots."

The use of "you" is too high-sounding, I am afraid it is only for Ling Xiaozi?However, there is no need to say too much.Su Song thought for a while, and then said: "It's just that someone else did it, and you have to watch it carefully. Don't make mistakes, but you can't verify the truth of the earth's rotation."

Han Miao laughed when he heard the words: "Brother Zirong, don't worry, there are so many eyes staring at you now. Those who spend money and effort are the ones who don't want to lose face in front of others. Just wait."

Sure enough, it only took ten days for the shop to build a high platform in front of Daxiangguo Temple.A full twenty feet, not much worse than the Iron Tower and Fanta.Fortunately, it is just a shelf, not a house, otherwise it will be suspected of exceeding the system.

After the shelf was built, the store owner was not in a hurry to perform the technique, but invited the jugglers from the tile house to use the method of climbing the pole and the rope for a few days.This is great, people who didn't know about it originally gathered around in front of the Daxiangguo Temple to watch the excitement.

Seeing that they have made a name for themselves, the shopkeeper finally gave up and announced that the pendulum will be suspended tomorrow.

On the second day, there was a huge crowd in front of the Daxiangguo Temple, and even the monks were mobilized to form a wall to prevent those onlookers from making trouble.

Zhen Qiong and Han Miao also changed their Daoist robes and crowded in the front row.Looking at the towering wooden frame, Zhen Qiong was speechless: "This is too high! How much does the frame alone cost?"

Han Miao smiled slightly when he heard the words: "Anyway, it's not spending our family's money."

Zhen Qiong was taken aback, then nodded again and again, isn't that the reason?

After finally reaching the hour, an old man who looked like a shopkeeper came up to the stage, bowed in front of the crowd, and said loudly: "This shop is the Feng family in the east of the city, and it specializes in the sale of missed engravings. It is a century-old shop for three generations. The clepsydra in the shop is the most exquisite, with a variety of styles, and even high-ranking officials often patronize it. Now the owner wants to add a self-ringing clock, and happened to see an article in the newspaper. It turns out that the pendulum can still There is a different way of saying it. This is when a high platform was erected in front of the Daxiangguo Temple, and I only hope to make everyone laugh. Gentlemen, if you see something novel, don’t forget my Feng family’s copper leak shop."

The words were mellow and mellow, which attracted a round of applause.The shopkeeper smiled and cupped his hands, and winked at the juggler beside him, and someone was carrying a rope and quickly climbed up the pole.Immediately, there was an exclamation, the wooden platform of twenty feet is almost going straight into the sky, what should I do if I make a mistake?Zhen Qiong took a deep breath, felt her legs go weak, and quickly closed her eyes.After a while, loud applause came from beside him, and he quietly opened his eyes and looked towards the wooden platform.

I saw a long chain already hung on the wooden frame, swinging gently in the wind, and a few servant-like men moved a large copper pendulum and tied it to the rope.The copper pendulum is not small, with a slender and sharp horn underneath, it may weigh fifty or sixty catties.Several people hung the copper pendulum, and tied the copper pendulum to a wooden pole on one side with a rope. Then someone stepped forward, spread fine sand on the ground, and drew a "ten" with white ash. as a marker.

When the copper pendulum stopped shaking completely, the shopkeeper of the Feng family came up to the stage again, and said with a smile: "I want everyone to know that this copper pendulum will draw patterns on the sand after a while. It's just that the change is quite slow, so it must be quiet." Only by waiting quietly can we see the doorway. Next to this shelf is the chime clock produced by the shop. You can watch the time, and you will be able to see the clue after less than half an hour."

Everyone followed his fingers to look at the wooden frame, and indeed a brand new chime clock had been erected, the style was a little different from the one in Han's shop, and it was more solid.The pointer on the disc above is pointing to Si time.

Seeing that everyone had seen his own clock, the shopkeeper nodded with a smile, fetched the candle, and burned the string that tied the copper pendulum.Without restraint, the huge copper pendulum swung suddenly.

With such a large pendulum, the feeling of moving is still very different.Everyone fell silent, holding their breath as they watched the copper pendulum sway left and right.This shaking method is really almost the same as the pendulum of a chime clock, what difference can there be?Could it be that if it is bigger, you can draw unusual images?

Zhen Qiong also looked at the copper pendulum, and then at the clock, all of them were fascinated.It was not until a quarter of an hour later that he remembered the sand on the ground and quickly lowered his head.This time, he opened his eyes wide.

When the big copper pendulum started to move, it moved along the vertical line in the white line of "ten" on the ground.In broad daylight, there was no wind, and no one was pushing the copper pendulum. Naturally, the drawn line should be firmly pressed against the white line.But now, slight changes have appeared on the sand surface, and the traces drawn by the copper pendulum have shifted slightly, moving out of the scope of the white line.

Is this dizziness, or some kind of spell?

Zhen Qiong was fine, she knew the result a long time ago, but she just watched it more and more attentively.Many people around rubbed their eyes.

"I'm afraid it's not a mechanism?"

"The Feng family's pendulum is really miraculous! Maybe the clock is not bad?"

"It's nonsense! Isn't it all published in the newspaper? It is said that there will be deviation!"

"Such a big one is biased? Is there a reason in general?"

The loud noise around him brought Han Miao back to his senses.Even after listening to Su Song, Shen Kuo and others, they are somewhat prepared for this matter.But actually seeing this situation still shocked him from the bottom of his heart.At this moment, Han Miao felt that the ground under his feet was spinning, making him dizzy and unable to stand steadily.

Fortunately, someone stopped him.

Zhen Qiong raised her head excitedly: "Brother Miao, this world is truly miraculous!"

Although the things of this style of Mono-ha are more difficult and bigger, not as straightforward as their good fortune ones, they are still equally interesting!

The eyes looking at him were shining, as if reflecting the stars, the sun and the moon, just like seeing them for the first time.

Han Miao laughed and held that hand tightly: "Qioner is right."
