A scholar of Zhenguan in the Tang Dynasty

Yang Sheng kicked and kicked the fat man all the way, "The sky is clear and the rain has stopped! Do you think you can do it again! Your good manners have been completely defeated by you."

"Yangtou, speak up if you have something to say!" The fat monk ran all the way.

Gu Qing smiled at this scene, came to the entrance of the village and said to a few children, "Do you want to read and write?"

A few brats playing in the mud looked at Gu Qing and said, "Brother Gu Qing, my parents said that we have no money at home for us to study."

"Do you still remember the broken house not far from the Taoist temple?" Gu Qing continued, "From tomorrow onwards, I will teach you how to read, and I will not charge you money."

For children in ancient times, books were a kind of luxury, and reading was something that poor people could not even imagine. For them, they were happy with a few mouthfuls of food at home.

Chapter 116 Physics

On the second day, Gu Qing brought Di Renjie to the bookstore contentedly. There were already quite a few adults bringing their children here. There were more than ten children. The number was a little small but it was considered a class.

Gu Qing said to Di Renjie: "From now on, you will be the class monitor here, and you must manage these children well."

"Yes!" Di Renjie answered earnestly holding a lot of books.

Several adults wondered, "Do you really don't want money?"

"No money!" Gu Qing said with a smile.

Gu Qing is a county magistrate in the village, and he is also a celebrity doctor. He has been familiar with the village for a year or two, so he handed over the children to Gu Qing. The children, big and small, were seated, and Di Renjie distributed a book to each of them.

Faced with these children, Gu Qing found that the youngest of them was only four or five years old, and the oldest was eleven or twelve years old, the age span was a bit wide.

Standing upright, Gu Qing said to them, "Tell me, what is your goal in life."

Child A said loudly: "Marry a daughter-in-law!"

Child B: "Eat meat!"

Child C: "Big house!"

……

Gu Qing raised his head and sighed, "What a simple child..."

After waving his hands to signal them to be quiet, Gu Qing continued, "The knowledge I want to teach you is different from that of the Zhihu people outside. I will teach you physics and science. This world is very big and has many mysteries."

"What is physics!" said a child.

The children are very familiar with Gu Qing, the guy who tells stories all day long and charges money, the children are very close to him.

"Good question." Gu Qing nodded, "Physics is a kind of seeking knowledge, such as why water doesn't flow to high places, and where does the wind blow from."

"Can Physics marry me a wife?" another child asked.

"If you learn physics, you might be able to marry a wife." Gu Qing looked helpless.

The practice of physics is very important. Gu Qing took the children out of the bookstore and saw a simple waterwheel by the river beach. This kind of waterwheel is very simple and needs manpower to drive. This kind of waterwheel is also called a dump truck. As long as it is in the water, it can turn.

"Today we are going to make a waterwheel." Gu Qing said, "You know that what a kite needs to fly to the sky is the wind, and it can fly into the sky by itself. We are going to make a waterwheel that can rotate with the water flow. waterwheel."

Di Renjie originally thought that the teacher would teach the children how to read, but he didn't expect to bring the children out and teach while doing it, which is different from the teaching method of ordinary bookstores.

Knowing that Di Renjie was puzzled, Gu Qing said, "Words are important, but example is also very important. Words teach, words teach, and words and deeds can't be delayed."

"Students understand." Di Renjie nodded, calling on the children to build the waterwheel together.

Gu Qing is directing, exhilarated!The adults who were farming at the side also looked over one after another, knowing that Gu Qing wanted to build a waterwheel that did not require manpower, they also came to help.

The wood was made into various shapes, and Gu Qing started to piece together some bearings and hubs according to his memory.

"Teacher, the water tubes have been made. I don't know if the size is suitable." Di Renjie brought two water tubes and said.

"Very good." Gu Qing looked at the water tube, "Hang these on the hub."

"Okay!" Di Renjie nodded and said.

Fang Xuanling was discussing with Li Er about how to deal with the Tuyuhun garrison in the palace, when Wang Qin walked over with small steps, "Your Majesty, Gu Qing has opened a bookstore."

"The bookstore?" Li Er was puzzled, "Kong Yingda told me that he wanted to invite Gu Qing and the Imperial College to teach him knowledge, but this guy didn't hear back and now he opened a bookstore by himself? Could it be that this kid doesn't like my Imperial College?"

"Does Kong Yingda know about this?" Li Er asked again.

"I probably don't know yet." Wang Qin said, "Gu Qing just opened the bookstore in his own village, but it's not very public."

After Fang Xuanling and Li Er finished talking about things, they left the palace early and rode a carriage all the way to Pushan Village. No one in the bookstore was in the mood to say that it was strange to see the words in front of the door, "Hiding in the small building to become a unified, regardless of his spring and summer. Qiudong, this kid is still indifferent."

Not far away, I saw Gu Qing talking and laughing with a large group of children by the river in the field.

Shaking his head and sighing in disappointment, Fang Xuanling said, "Let's go back."

The coachman watched the huge wheel hub being pushed up, and was about to drive the car when he looked back and was stunned.

Seeing the situation of the coachman, Fang Xuanling also looked back. The huge wheel hub was spinning, carrying water and pouring water into the field, only a small bracket was used to support the big wheel hub.

"Go and have a look." Fang Xuanling said and walked forward.

Gu Qing said to the children, "The flow of water has power, and the leaves will flow when they float on the water. The same water flow pushes the wooden cylinder to drive the water wheel to drive the water wheel to irrigate with water, saving manpower! If there is no need for irrigation, you can Using this lever, lift the wheel out of the water so it will stop moving."

At dusk, the children watched the water wheel turn and felt proud!This is the waterwheel they made with their own hands. A different kind of knowledge is sprouting in the hearts of the children. Gu Qing is not disgusted with this unchanging teaching method in ancient times, but he is not so satisfied. Reading does not have to be read only. Hu Zheye, finally learned that the four bodies are not diligent, and the five grains are not distinguished?

"That's it for today. I'll give you a task. You go to draw every part of the waterwheel." Gu Qing said, "You can work with a few people, or you can ask your parents to help."

"Ow!"

A large group of children agreed and dispersed.

"Gu Qing, this is..." Fang Xuanling looked at the huge waterwheel that could turn automatically without manpower, and was stunned, "You made this?"

"I made it with the children." Gu Qing looked at the huge water wheel and said, "It's amazing."

"Don't you want to go to the Imperial College?" Fang Xuanling looked at the waterwheel over and over again. The structure of the whole waterwheel can be seen to be complicated at a glance. It is so simple that a carpenter can do it. So the waterwheel can be made so simple.

"Students don't know anything about the Analects of Confucius, The Book of Poetry, the Spring and Autumn Annals." Gu Qing said, "I'm afraid that the Guozijian will not be able to do the sacrifice."

"If this method of making waterwheels is spread throughout the Tang Dynasty, how many people will have less labor." Fang Xuanling sighed.

Gu Qing explained, "Teacher, this kind of large waterwheel is also adapted to local conditions. The river here is wide and the current is fast, so the waterwheel can be driven. This effect may not be available in other places."

Fang Xuanling observed every detail of the waterwheel and said, "Are you just teaching the children this?"

"There are a lot of things to teach." Gu Qing said, "The things to learn are not only the Spring and Autumn Period of the Book of Songs, the teacher should be the student Ye Luzi."

"It's a pity that Kong Yingda has put in so much effort, he hopes you can enter the Imperial College." Fang Xuanling said again. "
