Infrastructure masters in the red building

Dongmen Pagoda was originally a tall pagoda in a temple near the east gate of the capital. It was built in the former dynasty.Over the years, even the monastery where the pagoda is located has been destroyed, but the pagoda itself still stands.Every night, the people of Shuntian Prefecture will hang bright lights on the tower, and there is never a dark day.

After an incident in Beijing in 14, it took the city several years to slowly recover.There used to be a night ban in the city, but it was also abolished ten years ago.The people in the city can also walk around the city at night, and the East Gate Pagoda has gradually become a major sight of the capital.A lot of night markets have also formed near the pagoda, some sell food for a living, some sell groceries, and some play games, which are always very lively.

Jia Fang took Qingsong and rushed to the east gate pagoda with the surging crowd.Along the way, he had already heard the whole story. It was a bet made by the Fourth Prince, that two balls of different weights, if dropped from the tower, would definitely land on the ground at the same time, instead of one after the other.

The opponent who bet with the fourth prince obviously didn't believe it, and insisted that the heavy ball fell to the ground quickly, while the light one fell to the ground slowly.So the fourth prince proposed that he would conduct this "experiment" in full view of the public.

"What is there to bet on? The heavy ones must hit the ground first?" Someone beside Jia Fang laughed loudly, "When will you see the light ones hit the ground first?"

"Yes, think about it, if the feather and the boulder are thrown from the tower at the same time, the boulder must hit the ground first? Could it be the fluttering feather?"

"But the Fourth Highness's bet is not that the light one will land first, but that the two will land at the same time."

"And it's not a feather and a boulder, but two balls, one is an iron ball, the other is a sepak takraw ball, one is ten catties, and the other is one catty. It depends on whether the iron ball hits the ground first or the sepak takraw ball first."

"Do you even need to think about it? It must be an iron ball! Can your sepak takraw ball make a 'bang' when you drop it, and hit a hole?"

"Come on, hurry up, do you want to bet on today's result? Let's go and bet a big one."

Guanpu shop is a shop that specializes in gambling and winning games. A few years ago, the imperial court strictly prohibited gambling with money, but with the gradual relaxation of the night ban, no one cares about this business.Although the government expressly prohibits it, it is very common for people to play and have fun in the night market, and occasionally spend a few big money to buy some chips to win the lottery.

"Everyone, the Fourth Highness is in high spirits today. He is throwing a ball on the East Gate Pagoda. The shop will cheer for the Fourth Highness by presenting ten lottery prizes. Everyone, please feel free to place your bets. Wait until the Fourth Highness...'experiment' is over. Small shops will be settled together.”

"Everyone who comes to Dongmen City often knows that the small shop has been closed here all year round. It has a good reputation and is innocent. At that time, the settlement will be based on the chips... Sigh, why do you all only receive red chips? No one will pay four. Your Highness is adding to the fun, will you get a blue chip?"

In front of this Guanpu shop, there are three kinds of chips: red chips, blue chips, and black chips.

The meaning of the store is to buy red chips, betting that the iron ball will land first, blue chips betting that two balls will land at the same time, and black chips betting that the sepak takraw ball will land first.

Everyone spends money to buy chips, and all the money for buying chips and the lottery that comes with the store are gathered in one place, and are divided equally among those customers who bet on the right treasure and use the chips to claim the lottery.

All the bamboo chips are placed in three large wooden barrels on the counter of the shop.I saw that there were not many red chips left in the bucket, but the blue chips and black chips were still full.

"Is it true that no one gets a blue chip?" The owner of the closed shop said with a playful smile, "In the end, you all can only win the ten-drop lottery I gave you."

"Win is your lottery!" Someone in the crowd laughed out loud.

"Give me all the blue chips!" A teenager's voice sounded from the crowd.Hearing this, the crowd immediately gave way to a master and a servant.

"This...do you really want these blue chips? Or...you can also consider black chips." The boss seemed to be selling products.

"No, I don't want black chips." It was Jia Fang who came, and after asking how much it was, Qing Song took the money out of his pocket and handed it to the boss.

"Young gentleman, please hold your hand high." The boss said with a smile, "The fourth highness's experiment has not started yet, what if there are still people who want to buy the little old man's blue chips in the future?"

When Jia Fang heard it, he thought it was right, so he said, "Let's keep half of it!"

Boss Guan Pu immediately made a bitter face - he might as well not say this.

Unexpectedly, Jia Fang turned around and said to the people gathered behind him to watch "Silly Boy Buy Guanpu": "The experiment done by His Highness the Fourth Highness today is to say that two balls with the same shape and size are thrown from a height at the same time. Whoever falls on the ground first. Think carefully, everyone, this is not talking about feathers and boulders!"

He continued to guide: "This proposition, when you first come up, you must think that the iron ball must hit the ground first. Why? Preconceptions are the first, and this is the impression! But at this time, we have already talked about money. Why don't you Give it a try, find two similar objects with different weights, throw them around first, and then come to a conclusion!"

Jia Fang is a handsome young man, standing under the lights of Dongmen City, his temples are cut like knives and his eyebrows are painted in ink, which makes his impression very deep.Besides, what he said was not unreasonable, so someone really found something of similar size around him and started throwing it on the ground.

"I have a bamboo waist card and a copper waist card, try throwing them on the ground together?"

"Hey, why does it seem...really, they landed at the same time?"

"No, no, there is still a sequence. You throw it from your hand to the ground, the distance is too short, and you can't tell the sequence when you throw it down. Only the Fourth Highness throws it from the high tower to see who comes first." Who's next."

"How about... try again?"

With a "snap", the two badges were thrown to the ground again.

"At the same time...at the same time!"

"No, no, there is a sequence!"

"No, no, definitely at the same time, I really saw it!"

"Boss, give me ten blue chips!" The blue chips that closed the shop finally opened after Jia Fang came.

Jia Fang waited under the pagoda of the east gate, feeling a little inexplicably excited.

When he handed the booklet "The Theory of Everything" to the fourth prince, he actually hoped that the principles and laws described in this thin booklet would awaken another consciousness: Seek truth from facts, don't take things for granted, everything Take evidence as the criterion.

He hopes that the "empty talk" atmosphere in this society can be changed, but the talk bureau he just joined told him clearly that the road is long and difficult, and it is still far away from realizing his ideal.

The fourth prince's "experiment" came out of nowhere, but it was eye-catching.

Jia Fangke didn't think that the prince was paying tribute to Galileo's experiment on the Leaning Tower of Pisa, but for the fourth prince who was clumsy and unwilling to talk too much in front of others, the result of "evidence" was this The prince's sharpest words, the most difficult words to refute.

This incident really gave him an unexpected surprise, causing him to forget even the unhappiness in Ruyiju before.

Soon, several figures appeared vaguely on the top of the tower.Immediately below the pagoda, some people shouted happily: "It's His Highness Fourth, Your Highness Fourth—"

The spectators happily waved to the people on the top of the tower, but were quickly driven back by the people from Wucheng Bingmasi.The servants of the Bingma Division led a thick rope and circled a large area under the tower, where no one was allowed to stand.But outside the rope circle, there were crowded crowds.

Every floor of this east gate pagoda is illuminated at night, and many lanterns and torches have been added to the bottom floor to illuminate the ground brightly.

Everyone looked up at the top of the tower excitedly. After a while, someone shouted: "Look, the ball—"

Jia Fang had good eyesight and could see clearly that it was the fourth prince himself, holding a ball in one hand, half of his body leaning out from the top of the tower.

Seen from the bottom of the tower, the two balls look identical, both black.But it can be seen that one of the balls is very heavy, because it is a little difficult for the fourth prince to hold it, and the other one looks very light. It should be the hollow rattan ball that the people say.

The fourth prince rushed down and nodded, and the servants below shouted loudly together: "Quiet!"

Under the pagoda in the east city, there was a real silence for an instant. Everyone looked up at the top of the tower, waiting to witness the result, and also waiting to see if their bets would bring them rewards.

The next moment, the fourth prince reversed his wrist at the same time, and the two balls fell at the same time, but in the blink of an eye, the balls had already reached the ground.There was only a loud "bang", and the iron ball smashed a hole in the ground.But the takraw ball just bounced lightly.

The bottom of the tower immediately cheered: "It's falling, it's falling!"

The crowd cheered for a while, and finally someone shouted: "At the same time, land at the same time!"

"I hit the bet, I hit the bet!" The person who yelled this was ecstatic.There are far fewer people who bet on "landing at the same time" than those betting on "the iron ball falls first", and betting on it means that you can get a lot of money.

"No... not..."

Gradually, another voice rang out from the crowd, "First and foremost! Sepak Takraw first!"

Jia Fang: ... What?

He suspected that his ears had misheard, this...how could it be Ms. Sepak Takraw?

"Yes, yes, I see it for real. The sepak takraw ball is indeed on the ground before the iron ball. It's about as soon as..." The man seemed not sure how to describe it, so he held back for a moment before saying, "It's almost It's about half the size of a ball."

Jia Fang immediately understood.

The fourth prince turned his wrists in sequence, probably because the takraw ball was light, so he turned his wrists a little faster.But even if it is only a few tenths of a second, for such a tall tower, this gap can easily be widened.

So this becomes... light land first?

At the bottom of the tower, there were all kinds of discussions, and more people were concerned about money—after all, except for the shop owner who closed the shop, everyone's money was exported.

"Don't be impatient, everyone! The Fourth Highness said that when the two balls were put down just now, there was indeed a slight deviation. The result just now does not count, so let's do it again."

Everyone breathed a sigh of relief this time, except for the boss Guanpu, everyone praised the fourth prince as "wise".

Jia Fang was a little anxious. In this kind of matter, "wiseness" is useless, what is needed is "rigorousness".He suddenly saw a young entourage coming down to the bottom of the tower to pick up the ball, he had just seen him, following the fourth prince, and he quickly shouted: "Hey, that one——"

He could only "Hello", after all, he didn't know the other party's name.But his voice was immediately drowned in the surrounding noise.

Unexpectedly, Qingsong next to Jia Fang suddenly bowed and slipped under the rope pulled by the servants.Li Qingsong was small and thin, he sneaked into the area enclosed by the rope in the dark, and the yamen servants didn't pay attention for a while.

Only then did Jia Fang realize that Qingsong stayed with the Fourth Prince in the refugee camp for a while and knew the people around him.

Sure enough, when Li Qingsong went over to say something, the commander immediately turned around and looked at Jia Fang.

Jia Fang beckoned, called Li Qingsong, asked him to listen to him, and talked for a while, then he straightened up and said to Qingsong: "You go, just wait for the time to talk, and clean your eyes by the way, help find such utensils .”

Li Qingsong agreed and asked: "Third Master, don't you go up to see His Highness Fourth?"

Jia Fang shook his head and said, "I bet on Guanpu just now." If he went up to the tower, he would not be accused of being interested afterwards.In order to ensure the fairness of the experiment, he should not come forward in person, right?

So Li Qingsong went up to the tower with the fourth prince's men, and the long-time attendant ran down quickly, holding a large rectangular box in his hand.

"I want to teach everyone that in the experiment just now, there was a very slight difference in the sequence when the iron ball and the takraw ball fell. His Highness has now changed the experimental method - he will put both balls in this box , and then pull out the latch at the bottom of the box, the bottom of the box will be opened immediately, and the two balls will definitely fall down at the same time..."

"Hey, isn't this the box for collecting incense money in the temple?"

Everyone saw that it was indeed the case: there was a slit in the box, and on weekdays, the common people prayed to God and worshiped Buddha, and put incense, money, copper, plate and silver into it through this slit.Even if monks and priests want to get the incense money, they have to turn the box upside down and shake it for a while, which is troublesome enough.

But the big guys never know that there is a flip cover under this, and when the latch is pulled out, all the money inside can be poured out directly.

Immediately, everyone laughed and cursed in unison: "I understand it. I dare to say that these bald asses and bastards spend incense money from good men and women in this way."

Then the leader quickly walked back to the tower with the box in his hand.The box appeared on the top of the tower in a short while, and was carried by two people at the same time, one on the left and one on the right. The fourth prince was beside him, waving his hands downward.

The yamen servants of Wucheng Bingma Division quickly tightened the long rope, telling the people to step back quickly.Immediately afterwards, the fourth prince pulled the latch of the box on top.The bottom cover of the box was lifted with a "snap", and the two balls contained in it fell down at the same time.

"At the same time, at the same time—"

"Simultaneous landing—"

As soon as the two balls landed, there was a burst of colorful sound at the bottom of the tower.Some of them were extremely excited because they had won the bet on Guan Puzheng, and some were because of the temporary adjustments made by the fourth prince to this "experiment"—it sounded very rigorous and reasonable, and deserved a compliment.

For a while, the superiors said thanks for their support, and the servants of Wucheng Bingmasi also took the rope.The people turned around one after another and were about to disperse.

Suddenly someone was yelling: "Do you want to know why the light and heavy balls can land at the same time? Do you want to know why the feathers only fall lightly? In case there are similar closing games in the future, think about it." Earn a little?—just read this pamphlet."

Those who left stopped immediately.

Jia Fang was also very surprised, he quickly moved closer, and saw the long attendant next to the fourth prince, holding a stack of thick books in his hand, each of which was a thread-bound booklet, on which were written four Big characters: "the principle of all things".

——The fourth prince reprinted his "Junior High School Physics"?

When the common people heard that "you can make more money by shutting down the game", they immediately surrounded them and surrounded them with three layers inside and three layers outside.Jia Fang could only hear someone asking, "How much is a copy?"

The chief immediately said, "One set of five papers."

Yu Ren immediately said: "It's really not expensive!" Just now people were imprisoned in Guanpu, and they paid ten and twenty Wen for flowers.Those who have money will pay immediately, especially those who have just followed suit and bought several copies at a time.The booklet in this handy hand was almost sold out.

Someone also asked: "I can't read, can I buy a copy of this book?"

The bystanders immediately laughed: "If you can't read, why don't you read a heavenly book?"

The man immediately replied: "I'll find a teacher to teach my son! Maybe my son can learn it?"

"That's right, buy it if you have money?" Seeing that the brochures in Sui's hand were empty, everyone dispersed one after another.

"The goods at 'Tianyi Bookstore' are also at this price. If you can't buy them, you can go there another day." Chang Sui yelled at the gradually dispersing crowd. "You also know the books of 'Tianyi Bookstore', you can't imitate them anywhere else!"

"Tianyi Bookstore?" Jia Fang immediately understood who wrote it after hearing the name.

"Third Master!" At the other end was Li Qingsong who rushed down from the pagoda and came looking for Jia Fang holding a pamphlet. "Third Master, look, I asked for this from His Highness Fourth."

Jia Fang looked at the booklet in his hand a little dumbfounded, thinking that Li Qingsong didn't know that the book actually came from him.

"Third Master, there are so many pictures in this book, I don't even understand them just looking at them, but Fourth Highness said that I can understand them after reading and thinking." Qingsong asked cautiously, "Can I borrow this book for a while?"

Jia Fang nodded boldly: "Yes. If you don't understand the characters, you can ask Shuangwen. If you don't understand the reasoning, just ask me."

As he said that, he left Dongmen City with a pocket full of money from Guan Pu's shop owner.There is no way, the money collected in Guan Pu's shop is all copper coins, and the lottery paid to him is also all copper coins.Jia thought about it, and later someone used a thread to thread it, and he transported it to Taoyuan Village.

When Jia Fang left, he didn't notice the third prince and his followers standing in the dark.

One of the retainers handed a brochure to the third prince and said flatteringly, "I bought it from the common people at a high price."

The third prince took it, flipped through it roughly, and complained with some dissatisfaction: "Isn't it already clear that Tianyi Bookstore has some to buy, and why do they pay such a high price? Isn't he spending so much time to get more people to see him?" This book?"

The diners couldn't figure out what the master was upset about, and they were so frightened that they kept silent.After a long while, I heard the third prince half angry, half terrified, saying: "What is the principle of all things? It is clear that it is the theory of investigating things to know, and empirical evidence first?"

"Unexpectedly... After so many years, someone wants to praise Feng Yi's 'new learning'?!"

"And it's the fourth child—"
