The first lady is sweet and sweet

Chapter 466 Stability (One More)
Shen Zhou's brown eyes looked at Qi Yaoyao and continued, "The two countries of Shu and Wu should be very fortunate that Ma Jun's military creations were not accepted because he was not good at words and was often envied and slandered by others. , only the water Zhuanbai opera, which was deeply loved by Emperor Wei Ming Cao Rui, was created."

"But those are all toys, it's really a bit..." Shen Zhou pursed his lips and gave her a look you know.

Qi Yaoyao turned her face away and closed her eyes, trying her best to restrain her anger.

"Yaoyao, what are you mad at?" Shen Zhouheng looked at her innocently and said, "That Water Turning Hundred Opera is indeed a toy! I remember it was recorded in the Records of the Three Kingdoms: It is made of large wooden sculptures to make it look like a toy. Wheels, cast on flat ground, submerged in water to make hair. Set up female music and dance elephants, to make wooden people play drums and flutes; make mountains, make wooden people dance pills, throw swords, edge walls, stand upside down, go in and out freely, and hundreds of officials run the office. Spring grinding, cockfighting, there are many changes. These three differences are also."

"Water turns a hundred operas, yes, they are puppets that can move." Qi Yaoyao's dark pupils looked at him and said, "That's right, Ma Jun made a big wheel powered by water, and then put all kinds of puppets on it. On this wheel, some of these puppets play music and dance, some play gongs and drums, some throw swords and throw balls, some do somersaults, and some walk ropes.

Hearing this, Shen Zhouheng smiled and said, "Wait for me to study it, and make it a play for my son."

Qi Yaoyao stood up abruptly when she heard the words, looked at him with her hands on her waist and said, "You are really going to piss me off."

"What's wrong?" Shen Zhouheng looked at her in confusion and asked, "Sit down, sit down, and speak slowly, how would I know if you don't tell me, and I don't know why you're angry." He blinked innocently. blink.

Qi Yaoyao picked up her skirt and sat down after hearing the words, "Now we can learn from the literature that this water turns a hundred dramas, using water as the driving force, can make such a small person move."

"Yes!" Shen Zhouheng nodded.

"You can do many things with water as power, such as a waterwheel." Qi Yaoyao said without thinking.

"I know." Shen Zhouheng nodded again and said, "I have seen both circular waterwheels and pedal-type waterwheels."

"So is it used in other places, such as spinning floats, looms, so that I don't have to chirp and chirp every day." Qi Yaoyao stared at him and said word by word, "Toys can also be changed. into a big toy."

"Uh..." Shen Zhouheng froze on the spot when he heard the words, and Taohua blinked for a long time before saying, "So it seems like you can try it."

"Do you know the revolving lantern?" Qi Yaoyao looked at him after calming down and asked again.

"I know, the lanterns that often appear during the Lantern Festival and Mid-Autumn Festival." Shen Zhou nodded his head, "You like it! We can do it. Your drawing is so realistic, it will definitely look better when you make it."

"Do you know what to do?" Qi Yaoyao looked at him curiously and asked.

"I know! There is an axle inside the revolving lantern, and there are paper-cuts on the axle. After lighting the candle in the lantern, the image of the paper-cut will be projected on the light screen of the lantern. The key technology of the revolving lantern is that the images of these paper-cuts can move continuously, so that the On the light screen, there are scenes of people chasing and changing scenes. It's very fun." Shen Zhou looked at her with high spirits and said.

"Then why does it turn?" Qi Yaoyao asked, looking directly at him.

"I don't know?" Shen Zhouheng pondered for a moment and looked at her and said honestly.

"These tricks are ingenious, think about the reasons behind them, why do they move without manpower? Can these reasons be used in our production and life? Improve production efficiency and improve our quality of life." Qi Yao Yao took a deep breath and looked at him and said slowly.

"Uh..." Shen Zhou's ginger pupils looked at her without blinking, "It seems that no one has ever thought about it so deeply."

"Yeah! These strange tricks were scorned and thrown away." Qi Yaoyao looked at him angrily and said with puffed cheeks.

Since ancient times, Chinese people have paid more attention to "skills" than "reasons".

Therefore, although we can find a lot of science from the water-turning-hundred-show and revolving lanterns, it is a pity that the old antiques only regard these things as "magic tricks" and fail to pay attention to the scientific principles behind them.

In later generations, a large number of Western objects came along with the powerful ships and cannons of Western powers. People were amazed at the exquisiteness and ingenuity of these rare things, but in their hearts they still felt that they were "wonderful tricks", and they were all sealed up.This has to be said to be a historical inertia that is difficult to change.

This revolving lantern lights the candles in the lamp, and the generated hot air forms a hot air flow to drive the wheel shaft to rotate.

At this time, the paper-cuts on the axle can be projected on the lamp screen of the lantern in turn, which also forms the external effect of you chasing after me, like a revolving horse, which is the origin of the name "revolving lantern".

The production principle of the revolving lantern is basically the same as that of modern gas engines.

In the Tang and Song Dynasties, there were already revolving lanterns, and the gas engine in Europe was not invented for barbecue until 1550.

After further development and evolution of the gas engine, there is a turbojet engine.The importance of the engine to the industry is self-evident.

Qi Yaoyao looked at him apologetically and said, "Sorry for the bad tone."

Sometimes modern people think that the ancients were particularly 'stupid', were the ancients stupid?On the contrary, people are smart!
Of course the ancients also knew that technology can bring wealth, but wealth was sometimes not the most important thing to the ancients.

For rulers, the core appeal is stability, not efficiency.

Stability can sacrifice everything!
If technology brings only a pure increase in production efficiency, then both the ruler and the ruled will accept it.

The problem is that technology will inevitably affect distribution, production relations, and changes in class power while improving efficiency.

And it is difficult to predict how it will affect it.

That's what really kills.

The unknown is the most terrifying!
Viewing the problem from a different angle has different consequences.

The biggest feature of this world is that there is no sustainable exponential growth, and there are cruel stock competitions and zero-sum games everywhere.

For example, the plough used for arable land is innovated step by step, but any increase will be quickly flattened by population growth.

The result is that from ancient times to the present, at any time, the average living standard of the people has been struggling on the line of food and clothing.

Natural and man-made disasters, together with wars and plagues, have a more severe impact on the population than technology.

So what else could technology be if it wasn't "wonderful tricks"?
