Chapter 1559 Mechanics and University

The early winter in Suzhou is still charming, the mist is like cooking smoke spreading on the river, and then the boats are looming.

"The direction of the force can change the trajectory of the 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 overcame gravity and friction, and slid in the direction of the force."

A group of young people are watching, and some are even recording.

"There are two concepts emerging here."

Gao Jingyan explained: "The teacup has weight. When it slides, it actually creates friction with the tabletop. Of course, this is also a kind of resistance. Let me say it loosely. Lubricate as much as possible, so is the resistance reduced? It is easier to run.”

Gao Jingyan then pushed the teacup to the smoother place, and said: "Look, on a smooth place, moving the teacup can save effort, so you must remember the three elements of force, not only remember it, but also learn from life. to observe in it, and to observe the force at play in it."

"As for the friction force, this is ubiquitous. If you rub your hands on your face, friction will be generated between your hands and your face. If you rub hard, the friction will generate heat..."

Gao Jingyan saw his junior brother Zeng Guang sorting out the books, and said, "As for the friction force, let Zeng Guang tell you about it. Remember, these are wonderful phenomena that happen all the time around us. , but it’s not mysterious, it’s just that no one has summed it up before.”

After Gao Jingyan finished speaking, he left the cabin, followed by the owner of the ship, Wang Fu, who is also a fan of science.

"Brother Jingyan, these are children from poor families, it's not easy to come out, so I'd better teach them as much as possible."

Gao Jingyan is a son of a rich family. Since he became fond of science, every time the students of the academy come to teach, most of the lectures are at his home, and the board and lodging, including those who come to study, are all paid by his home.

The fog ahead is full, just like science at this time, the future is uncertain.

"The head of the mountain is a firm believer in the spread of science. He said..."

Gao Jingyan showed admiration, and said: "Shan Zhang said that science is the study of nature. It is not lofty or metaphysical. After learning it, you can know the truth and the truth that is relevant to you. And it can be used. It is scientific to apply what you have learned. Greatest merit, so I will do my best to let science sow more seeds in the South."

"This time, the head of the mountain personally arranged for us to come out. This is the official start. Taizheng, you have been studying for the past few years. Let's walk together. The head of the mountain is watching us, and His Royal Highness will also watch us in the future."

The word "Taizheng" made Wang Fu feel a little sweaty. It was written by his father, an old man who longed for a high-ranking official in his family.

"Brother Jingyan, ever since I learned science, my younger brother can't read those books anymore. If my father hadn't been enlightened, my younger brother would definitely run away from home and go to an academy to study, so don't worry, science... my younger brother is still thinking about the day To be...the kind of person who can change the world."

Gao Jingyan smiled and said, "Do you think I don't know? Back then you went on a hunger strike for several days, and your mother made a fuss for a long time before uncle changed his mind."

Wang Fu blushed, and said, "I like science, and I like the feeling of knowing how hard I used to take a step."

Gao Jingyan said with a smile: "Everyone likes this feeling. Confucianism is good, and one should also learn it, but the emphasis is on differences. This is what Shanzhang said. Confucianism has forged a foundation and national tolerance, and science will make a country strong, giving that foundation and tolerance. Plated with a layer of toughness and confidence."

"You have to distinguish between the primary and the secondary. If you can't tell the difference, and the concepts are confused, there will be troubles in the future, and those students will argue."

In fact, the family had already found a livelihood for Gao Jingyan, and even several yamen in Jinling said they were open to accept students from the academy, but no one went, because everyone knew that he was the one who sowed the seeds.

"The boat is coming!"

At this time, there was a shout from the opposite side, and the boat on this side immediately pulled over.

The fog was broken, and a boat slowly approached.

"...The so-called Qi Qi family is cultivating his body..."

A childish voice came from the cabin,

The boatman is shaking at the stern of the boat, and the mist is like a fairyland, making people fall into an ethereal realm.

"...increasing pressure increases friction..."

"...the one who despises and hates it is rejected, and the one who fears it is rejected..."

"...you can also make the surface of the object rougher, which can also increase the friction..."

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

The contents of the university flashed through Gao Jingyan's mind like flowing water. He watched the boat disappear into the mist again, and said faintly, "This is the confidence of Confucianism. Let's start spreading, just ask for the quantity..."

"But didn't you say that quantitative changes lead to qualitative changes!"

"Yes, these are the words of the head of the mountain, and then those people will continue to spread science. When they find out that something is wrong, it will be... either trying to see each other, or tearing each other down. However, science is not superstitious after all, so it cannot appear openly for the time being. In the hall."

"There is a mountain leader!"

Gao Jingyan encouraged Wang Fu: "The head of the mountain said that the timing is very important. Before the timing occurs, our task is to spread the word."

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

After entering, someone led the students to a temporary classroom, and Gao Jingyan went to meet Wang Fu's father, Wang De.

"...My nephew is here to bother uncle again, I am ashamed."

Wang De looked like a rich man, with a... rather round, ruddy face.

"Then what are you doing out there?"

Wang De got up, his voice was resonant, and his face was flushed, and he looked at the world seriously.

"You can stay here when you come. The Wang family is not short of that little money. If you don't want to, it's disgusting. Naturally, the old man wants to clean up people! Hahahaha!"

Gao Jingyan bowed and said, "Thank you uncle, my nephew once mentioned uncle to the head of the mountain, and the head of the mountain said that it is rare to find a person like uncle without prejudice, and he is willing to bear the place and board and lodging, this is a warm heart, etc. If I have a chance in the future, I will have a drink with you."

"oh!"

Wang De leaned back violently, and then said with a smile: "How dare I dare! How dare this old man drink with Xing Hebo, as long as he can invite you in person, it will be enough to show off everywhere, hahahaha!"

Laughter filled the room, and Wang De finally said: "Go, you young people go to make a fuss, and the old man should go out and find a few old friends to catch up with each other."

...

In the next few days, Gao Jingyan and Zeng Guang devoted themselves to teaching these students, and then sent them away with their own hands.

"We're going to go down and have a look."

Gao Jingyan and Zeng Guang leave with burdens on their backs.

Wang De mused, "Are you going to go like this? Board and lodging will be difficult."

Gao Jingyan raised his eyebrows and said, "Uncle, don't worry, in the past few years in the academy, we have all learned how to survive in the wild and survive starvation."

"You are like monks begging everywhere, is it worth it?"

Wang De looked at his son and sighed, "I don't know what you are studying, but I know one thing. You will be successful in the future!"

Wang Fuxi said: "Father, that child should follow along."

As soon as Wang De stared, Gao Jingyan smiled and said, "No need, some people will come here to ask questions from time to time, if you're not here, who can they turn to?"

"Farewell!"

Gao Jingyan and Zeng Guang cupped their hands and turned to leave. Wang De looked at their backs and sighed, "Science, for my father, I know that those scholars outside don't want to see science, but you like it, and Xing Hebo and His Highness are backing me, for my father." Just... hey!"

But Wang Fu was a little disappointed, he felt that he was a deserter.
