The early winter in Suzhou Prefecture is still charming, the mist is like smoke spreading on the river surface, and then the boat appears and disappears.

"The direction of force can change the movement trajectory of an object, you see."

In the cabin, Gao Jingyan gently pushed the teacup and said, "I gave the teacup a force from the side, and then the teacup overcomes the gravity and friction and slides in the direction of force."

A group of young people were watching from the side, and someone was even recording.

“Two concepts emerge here.”

Gao Jingyan explained: "The teacup has weight and actually produces friction with the tabletop when sliding. Of course, this is also a kind of resistance. Let me say it is loose. For example, if our water truck can be lubricated as much as possible between the shaft and the sleeve, will the resistance be reduced? It will be lighter to run."

Gao Jingyan then pushed the teacup to the smoother place and said, "Look, moving the teacup can save effort in a smooth place, so everyone should remember the three elements of force, not only should they remember it, but also observe from life and observe the role of force in it."

"As for friction, this is everywhere. When everyone puts their hands on their faces, they will produce friction between their hands and faces. When rubbing them hard, the friction will generate heat..."

When Gao Jingyan saw his junior brother Zeng Guang sorting out the books, he said, "As for friction, let Zeng Guang tell you about this. Remember, these are wonderful phenomena that happen all the time around us, but it is not mysterious, it is just that no one has summarized it before."

After saying that, Gao Jingyan left the cabin, and then the owner of the ship, Wang Fu, also a fan of science, followed.

"Brother Jingyan, these are all poor families, and it is not easy to go out, so try to teach as much as possible and teach more."

Gao Jingyan is a rich child. After he likes science, most of the students from the academy come to teach at his home, and the food and accommodation, including those who come to study, are at his home for the expenses.

The fog is everywhere in front of you, just like the science at this time, and the future is confused.

"The mountain master believes in the spread of science, he said..."

Gao Jingyan showed admiration and said, "The Lord of the Mountain said that science is the study of nature. It is not tall and invisible. Once you learn it, you can know the truth and the relevant principles. And it can be used and applied to what you have learned. This is the greatest advantage of science, so I will do my best to let science sow more seeds in the south."

"This time the mountain master arranged for us to come out personally. This is the official start. Taizheng, you have been studying for the past few years. Let's go on together. The mountain master is watching us, and your highness will also watch us in the future."

The word Taizheng made Wang Fu feel a little worried. This was the work of his father, an old man who longed to be a high-ranking official in his family.

"Brother Jingyan, since I learned science, I can no longer read those books. If my father had not been enlightened, I would have run away from home and went to the academy to study. So don't worry, science... I still think about what day I can become... the kind of person who can change the world."

Gao Jingyan smiled and said, "Do you think I don't know? You took a hunger strike for several days, and your mother made a fuss for a long time before my uncle changed his words."

Wang Fu was ashamed and said, "I like science and the feeling of knowing what force I used to take one step."

Gao Jingyan smiled and said, "Everyone likes this feeling. Confucianism is good and needs to learn it, but it focuses on differences. This is what the chief of the mountain said. Confucianism has created the foundation and national demeanor, and science will make the country strong and put a layer of toughness and confidence in that foundation and demeanor."

"We need to distinguish between the primary and secondary, and we cannot distinguish them, and our ideas are confused, and there will be storms in the future, and those students will have disputes."

In fact, my family had already found a livelihood for Gao Jingyan. Even several yamen in Jinling said that they could openly accept students from the academy, but none of them went because everyone knew that they were the ones who sowed seeds.

"The ship is coming!"

At this time, the opposite side shouted, and the ship here immediately leaned aside.

The fog was broken and a ship slowly sailed over.

“……The so-called "Shi Shi Family" is cultivating his body..."

A tender voice came from the cabin, and the boatman shook his stern, and under the fog, he fell into an ethereal state like a fairyland.

“…Increasing pressure can increase friction…”

"……It is despised and jealous, and it is despised and jealous, and it is despised and jealous..."

“…It can also make the surface of the object rougher, which can also increase friction…”

Gao Jingyan stood at the bow of the boat with his hands behind his back, and the two ships passed by. He slowly turned around and saw a thirteen or fourteen-year-old boy sitting in the cabin, shaking his head and reciting...

The content of the university flashed through Gao Jingyan's mind like flowing water. He watched the boat disappear into the fog again and said quietly: "This is the confidence of Confucianism. No wonder the mountain captain did not open a new academy again, but chose to start spreading from below, only asking for quantity..."

"But you didn't say that quantitative change causes qualitative change!"

"Yes, this is the words of the mountain leader, and then those people will continue to spread science. When they find something wrong, they will... either find out what they want or break up with each other. However, science is not a manifestation of science after all, so it cannot appear in the court with dignity for the time being."

"There are mountain leaders!"

Gao Jingyan cheered Wang Fu and said, "The Lord of the Mountain said that timing is very important. Before the opportunity appears, our task is to spread."

Then the boat docked and the group followed Wang Fu's house.

After entering, someone took the students to the temporary class, and Gao Jingyan went to pay homage to Wang Fu's father Wang De.

"...I'm sorry to bother my uncle again."

Wang De looked like a rich man, who looked quite round and red.

"So what are you doing when you see each other?"

Wang De stood up, his voice was loud and his face was full of redness, and he really looked at the four seas.

"Let's stay there when you come. The Wang family doesn't have that little money. If you refuse, you will dislike it. I will naturally have to deal with people! Hahahaha!"

Gao Jingyan bowed and said, "Thank you, uncle. My nephew once mentioned my uncle to the mountain leader. The mountain leader said that it is rare for people like my uncle to be without prejudice. He is willing to bear the place and food and accommodation. This is kindness. When you have the chance in the future, you will definitely have a drink with you."

"oh!"

Wang De's body suddenly leaned back, and then smiled and said, "How dare you? I dare not drink with Xing and Bo. As long as I can ask for help in person, it will be enough to boast about it everywhere, hahahaha!"

The room was filled with laughter, and Wang De finally said, "Go, you young people are going to make trouble, I'd better go out to find a few old friends to talk about the past."

...

In the following days, Gao Jingyan and Zeng Guang taught these students with all their hearts, and then sent them away with them.

"We're going to take a look below."

Gao Jingyan and Zeng Guang said goodbye with their bags on their backs.

Wang De pondered: "You are going like this? Eating and living will suffer."

Gao Jingyan said with a grave brow: "Uncle, don't worry, in the past few years in the academy, we have learned to seek life in the wild and never starve to death."

"You are like monks begging for alms everywhere, are you worth it?"

Wang De looked at his son and sighed: "I don't know what you are studying, but I know one thing that you will definitely have a future!"

Wang Fuxi said: "Dad, let's go with me too."

Wang Degang stared at him, and Gao Jingyan smiled and said, "No need, there will be some people here from time to time to ask questions. Who are you looking for if you are not there?"

"Goodbye!"

Gao Jingyan and Zeng Guang bowed and turned away. Wang De looked at their backs and sighed: "Science, for my father, I know that those scholars outside don't like science, but you like it, and there is His Highness Xinghe Bohe who is supporting him. For my father... Alas!"
