Great Song

The new year has just started, and Han Miao has a lot of things at hand.In order to expand the trading of sugar and spirits in the newly opened Bianqian, to open up sugarcane gardens in Lingnan, and to open up oil fields in Shanzhou, it is necessary to negotiate with multiple parties and increase the intensity of mining and refining.He didn't have enough skills to do his own thing, so he didn't go to the banquet with Zhen Qiong.

But unexpectedly, these three people came to the door in turn.

Hearing Zhen Qiong clarified the situation clearly, Han Miao pondered for a moment, and asked, "Brother Zirong is worried that this matter is related to the 'Earthquake Theory' at all, and you don't want to be too conspicuous?"

If only the results of the research are made public, there are many ways.Whether it is listed on the imperial court, published in "Ri Xin Bao", or elaborated in "On Good Fortune", it can quickly attract the attention of the world.But Su Song didn't do this, obviously still has some concerns.

After all, the rotation of the earth is the core of the "earthquake theory" and the precursor of the "heliocentric theory".Once this is broken, the saying that the earth is in the sky and the stars go around the sun will be subverted.Shen Kuo may not be afraid of such a single-minded person, but Su Song may not be.He is sophisticated and thoughtful, how could he act rashly?

Su Song didn't hide anything, and simply nodded: "This is a big matter, so we must think of a safe way."

The "Earthquake Theory" is a major matter after all, even if the court disputes over the new law, it will not take it lightly.Su Song also thought for a long time before finding Han Miao.After all, there was an appointment before, and this official Han is also a whimsy.Discuss one or two, maybe we can come up with a solution.

Han Miao nodded slightly, and asked again: "Does the pendulum have to be made really big?"

"I'm afraid it has to be as tall as a tower, and the hanging cone is heavy enough to have an intuitive appearance. And the chain has to be modified so that it can rotate in all directions so that it won't be controlled by the rotation of the earth." Su Song replied immediately. road.

He also calculated that the speed of the earth's rotation is much slower than the swing of the iron ball. If the chain is too short, it will definitely affect the effect of its observation.The weight of the suspension cone is the key to resisting air resistance.To make it swing for a long time, both are indispensable.As for the chain rotating in all directions, it is easier to solve the problem of not being bound by the earth's rotation, just make a mechanism at the top of the chain.

The Fan Pagoda is 240 feet long. Such a large hanging pendulum is a big problem both for production and display.Han Miao thought for a while, then suddenly asked: "I heard from Qiong'er, you also came up with a method of using a pendulum to keep time?"

Unexpectedly, Han Miao would lead the topic to this, Su Song raised his eyebrows and said: "That's right. As long as there is an escapement mechanism, it can be made into a water-powered time-lapse. It can achieve a similar effect. According to my observation, regardless of the length of the suspension rope, the swing of the pendulum is equal every time, and it can be used for timing very accurately.”

Hearing this, Han Miao showed a smile: "In this way, can't we make a new type of timer? I'm afraid it is more accurate than the engraving and the corona."

"That's not necessarily the case." Su Song could not help but seek truth from facts, "The swing of the pendulum requires external force. If it is left alone for a long time, it will stop swinging by itself due to the barrier of the atmosphere. There must be something pushing it to make it last for a long time."

"Brother Zirong can solve this thrust?" Han Miao asked indifferently.

"It should be possible..." Su Song paused, "But what does this thing have to do with what I said before?"

Isn't it discussing how to make a pendulum and reveal the secret of the earth's rotation to the world?Why did it suddenly switch to timing again?Could it be that Han Miao took a fancy to the business opportunities here?

Facing the bewildered eyes of the three, Han Miao suddenly laughed: "It's all hanging, why don't you use it to attack and hide Chen Cang?"

What is the darkness?Zhen Qiong was at a loss, feeling more and more inexplicable.Su Song frowned slightly, and tentatively said: "Jing Sheng wants the world to use the pendulum to measure the world instead of the pendulum of timekeeping?"

"As long as there are more and more new timers, the characteristics of the pendulum will be self-evident. If someone suddenly mentions this object, it can have a weird swing mode. Why don't people be curious? And when the real object is placed in front of you, Naturally, someone will be able to guess the truth behind it," Han Miao said with a smile.

"This method is wonderful! It is convenient to push the boat along the current." Su Song finally realized it, and couldn't help clapping his hands and praised.

Shen Kuo also understood the meaning of Han Miao's words, but frowned slightly.However, this is Su Song's idea after all, and there are indeed risks. He will not be able to comment on it if he sees people's approval.

Only Zhen Qiong was still a little confused: "Wait, let's not mention the big event of the earth's rotation? Isn't this also going to be famous in history?"

Han Miao couldn't help but laugh when he heard the words: "What's the point of making a name for yourself? It's better to make some money first, and then let things fall into place."

Too.Shen Kuo and the others are still using pen names, and they don't seem to care about fame, making money is more important.Zhen Qiong was stunned for a while, then nodded vigorously.

The long-awaited spring finally came to an end, the examination papers were released, the horses were paraded through the streets, and there was the next matter of conferring officials.The entire city of Tokyo was buzzing with joy, and it was very lively for a while.Although the imminent implementation of the "Gong Ju Law" still has some aftermath, and the dispute over the "Service Recruitment Law" has not subsided, the political controversy has indeed cooled down, and scholars have inevitably diverted their attention and began to pay attention to other things.

One is the fermentation of the "gravity theory".After several months of intensive research, those scholars who are familiar with the "hundred heaven theory" began to talk about "the earth is like a chicken".Don't you see that armillary spheres are round?When sailing a boat on the sea, one sees the sail first, and then the hull.Maybe a round earth is also possible?

Faced with this situation, Zhang Zai and others who supported the "Xuan Ye theory" also introduced the theory of the circle of the earth.But this statement is somewhat untenable.After all, "Xuan Ye Shuo" talks about the sun, moon and stars floating in the boundless universe. If the earth is also round, wouldn't the trajectories of the stars be messed up?Without the control of the sky, how can the sun rise and the moon set?

At this time, Cheng Yi, who had waited hard for three months and had not waited for Mengxi to say anything else, couldn't sit still, opened the door of his study, and preached his own "Confucianism".

"Huntian Theory" is undoubtedly orthodox, because the earth has gravitational force, which makes everything stand on the earth.The so-called "vacuum" doesn't exist at all, it's just a vision that only appears when the atmosphere is sparse to a certain extent.There is such an atmosphere around the sky and the earth, so no bird can approach the sun and the moon at the top of the zenith.

As for the atmospheric pressure, it is just a sign of gravity, and it is the constraint of the way of heaven on all things.The sun rises and the moon sets, also affected by gravity.Because the ground is a sphere, half of it is solid soil, and the other half is sea water, so the "density" is different, and some forces are uneven.Therefore, the gravitational force changes accordingly, weak in the east and strong in the west, and the sun is drawn to rise in the east and set in the west, which remains unchanged from ancient times.

All these "heavenly principles" are arranged by God.If there is no gravitational force to attract the mountains, wouldn't the fields be overturned when there is an earthquake?And a gentleman should also take root in his feet, follow the arrangement of the way of heaven, and abide by the principles of morality in order to make the world peaceful.

It has to be said that Cheng Yi's foundation in Confucian classics is not bad.When this theory came out, it was appreciated by some scholars.Now that there are so many right and wrong truths popping up in one brain, everyone feels that they have nothing to rely on for what they have learned half their lives, so naturally they hope to hear theories that conform to their own cognition.

As a result, Cheng Yi's reputation regained a little boost.Many scholars also think that although this person is not very good at running a newspaper, he still has a certain level of Confucianism.As a result, the Cheng Mansion had many visitors, and people frequently came to discuss the truth of the "Huntian Theory".

But the common people don't care about what these old scholars pay attention to.What is the gravitational pressure, the roundness of the earth, and what has it to do with them?It's a new product from Hanjiapu, which is even more amazing!

No, after a year of silence, Han's Shop finally launched another new thing.

"Straight mother thief! What are you squeezing? Didn't you see that I'm about to lose my footing?" The man standing in the front row angrily scolded.

"Is it because I'm crowded? Don't you look at how many circles are inside and outside? What's the matter, let you get closer?" The other, not to be outdone, retorted.

In the past, when these two quarreled, they would attract a crowd of onlookers.But today, everyone around him scolded him in unison.

"What's the noise? It's almost time!" "Shut up! Don't let us miss the sound!" "Be quiet, everyone in front of you is quiet!"

A group of people were talking, but the two of them didn't dare to say anything. They each turned their faces angrily, and continued to look at the tall and conspicuous thing at the door of the store.After a while, with the sound of "dang", the crisp bell rang suddenly.

"Hey! It's time! It's time!" "It really rang, but it didn't ring!" "It's already said to be a 'self-ringing bell', so why should someone ring it?" "It turned again, turned again, odd Ya..."

Standing on the periphery, a young man dressed as a scholar gasped: "This thing can really make its own noise?"

The friend beside him smiled and said: "Isn't that right? This is a new product from Han's shop. It is called 'Self-ringing Bell'. It is shaped like a sundial, but it doesn't need to shine on the sun. The needle is like a leak, but it doesn't need to be irrigated. As long as it is placed at home, Whether it is day or night, you can tell the time!"

The "self-ringing bell" he mentioned was the huge wooden cabinet standing in front of the shop.It is said to be a wooden cabinet, but in fact this thing is divided into upper and lower parts.The upper one is shorter, with a disc made of brass, engraved with the words of twelve hours, and a short line is drawn in the middle of each hour, marking the word "正".There are also two pointed pointers on the disk that keep moving.The short hand points to the word "Shen Shi", while the long hand moves in circles, as if urging the short hand to move forward.

Under the astonishing copper plate, there is a big pendulum.The pole is slender, with carvings all around, making the round copper hammer a bit slimmer.The entire pendulum is covered in transparent glass, swaying and swaying non-stop for a moment, making people dizzy.

Such a strangely shaped wooden cabinet is exquisite in workmanship, and the ticking pointer can catch everyone's eyes.Even if the bell was only rung to announce the time, it still attracted many people to watch, and they were reluctant to leave for a long time.

"It's really rare to see. If only I could buy one to take home..." The young scholar liked it more and more, and couldn't help saying.

Before the friends around me said anything, laughter came from the crowd: "Xiao Lang, you don't know the price of this clock, do you? The cheapest one costs 90 yuan, and there are 200 million yuan. Who wouldn't want to want?"

These words immediately made the scholar's face turn red. 90 yuan, can it cover the prime minister's salary for three months?Where does he have so much money!

However, before he could hide his face and leave, there was a sudden commotion at the door of the store.I saw a few people who looked like servants carefully moving a wooden cabinet and put it on the ox cart outside the door.

"Look, didn't that just enter the store? A chime clock has been moved out so quickly!" Someone exclaimed in a low voice.

"Look carefully, it belongs to Sun Yuan's family in the east of the city. They have already become the county master, so what's a mere chiming bell?"

These words immediately drew envious gasps.Of course, some people's teeth were gritty, and they groaned: "This new product in Han's shop, which one has not been imitated in ten days and half a month? Why not wait a few days, when there are more imitations on the market, just buy cheap ones It's..."

Someone on the side laughed when he heard the words: "That's what you, a poor man, think. The quality of the Han family's products is top-notch. Even if the perfumes that are all over the street are not the Han family's 'Four Seasons Fragrance' Best? Not to mention things like glazed lamps, even those who study, don’t they all wear glasses from the Han family? Why don’t you choose the best ones and buy the latest ones?”

These words immediately made the pantothenic speechless.Isn't that right? Over the years, there have been countless imitations of the novelties of the Han family shop, but no one can shake the status of the Han family.Other people's things are used by the nobles in the palace. When it comes to the word "Kit Kat", it is the only one in Tokyo after all.

The idlers just watched the excitement, and those who were doing business couldn't sit still.I don't know how many companies bought the self-ringing clock and went back to study it. I only hope that this thing can be copied as soon as possible.There are also many rich and leisure scholars who bought chime clocks specially for enjoyment.Whether this thing is practical or not is second to none. Just a pendulum can make the pointer move steadily and accurately, which is amazing to watch.Although it still needs to be wound every day, but at home, the taste is different.The pointer ticks and the pendulum shakes, creating a sense of leisure and elegance.

Of course, among these people, it is unavoidable that there will be a few boys who are bewitched by "Mengxi Bi Tan" or "Theory of Good Fortune", secretly dismantling the chiming clock, wanting to study the truth.Few really figured it out, but quite a few were broken.It's also thanks to the Han's shop in charge of repairs, otherwise it wouldn't be a matter of family law.

When this kind of thing spread, it was often treated as a joke.But there are not a few people who are looking forward to the publication of new articles in "Theory of Good Fortune".What is the principle of this self-ringing bell? It is really obsessed.

Unexpectedly, no one has explained the principle of the self-ringing clock and the escapement mechanism in detail, but a short article was first published in "Ri Xin Bao".
