Chapter 176: Teaching by Word and Deed
Yang Hao looked at the young official and said in his heart, "!" What's going on with this product? Do you want to seize the opportunity of Lao Tzu to pretend to be forced? ”
The young official said excitedly: "Chief, this clod of earth is not as strong as this land!" ”
When Yang Hao heard this, he almost spurted out a mouthful of old blood.
It's just that when the rest of the people heard this answer, their faces suddenly changed.
Yang Hao secretly said in his heart: "These people are really brain-opening, this is trying to thunder me to death, and they want to rob me of the position of the leader?" ”
Seeing that everyone was waiting for him to announce the answer, Yang Hao looked at the young man and said in a deep voice: "This idea is very interesting, but what I want to say is not this." ”
The young official couldn't help but be a little disappointed, looked at the crumbled clod of dirt, frowned and pondered.
Yang Hao looked at the crowd: "You asked before, will the people on the other side of the ball fall, and the clod of soil I just threw explained everything." ”
Seeing that everyone was still at a loss, Yang Hao continued: "Everything on this earth, just like that clod of soil, is bound to the ground by an invisible force, no matter how high you jump, it will eventually fall on the ground.
The person on the other side of the ball will also be bound by this force and will not fall out of the ball.
And the earth under our feet is so big that even if it is a round ball, we can only think that it is a plane when we stand on it.
”
After Yang Hao's explanation, everyone suddenly realized, but the young official just now had a hot face.
It was only after he remembered that when Yang Hao told that magical story, he had already mentioned this invisible power, and what he had said, his face couldn't help but be a little hot.
Yang Hao said: "It's no big deal to answer wrong, as long as you use your brain to think, it's a good thing." ”
When the young man heard this, he was extremely grateful to Yang Hao in his heart.
"Chief, if this world is a ball, then why can't we feel it at all, our subordinates still don't understand."
Yin asked.
Yang Hao said: "This is not difficult to understand. ”
Yang Hao said, picked up the wooden stick and drew a triangle on the wall, and then drew a square, a pentagon, a hexagon, and an octagon.
"If you look at these patterns, each pattern has an extra line, and as these lines become more and more numerous, all of a sudden they get closer to the circle, and we can imagine if there is a large enough space.
Let's draw more lines of patterns, and if there is a person standing on one of the lines and looking at the line in front of them, it is like we look at the world. ”
Yang Hao directly used the most intuitive method to explain the circumcision method, and used this vivid and vivid way to lay the foundation for the future knowledge of plane geometry.
Seeing that someone was already on the ground, according to the method Yang Hao said, he drew polygons one by one, but without Yang Hao's technique, the painting was a little crooked, but slowly a twisted circle could appear.
The real circumcision method is based on regular hexagons to deduce, and the plane geometry has not yet officially begun, and Yang Hao does not plan to instill too many things in them.
Wei looked at the suddenness on the wall and said excitedly: "Chief, my subordinates have an idea. ”
Yang Hao said in a deep voice: "What do you think?" ”
"According to the leader, this method of drawing a circle can be used to improve the wheel."
When Yang Hao heard this, he suddenly thought of this, and to be able to think of this is to confirm that there is a specialization in the art industry.
He thought of using this method to teach the concept of geometry, and Wei has been engaged in the development of tools for a long time, but he can integrate theoretical knowledge into practical application, Yang Hao admires it very much, and can't help but secretly admire his ability to use people.
As a leader, you don't have to be a perfect person, but you must have the ability to know and use people.
"This is a good idea, you can study it in the future, if the wheels made in this way are better than now, in the future, the wheels of our people will be made according to this method."
Hearing this, Wei nodded and said, "The subordinates obey the order." ”
Science and technology are the primary productive forces, Yang Hao agrees with this sentence.
He did not understand military affairs, did not know how to march and fight, but he knew how to develop technology.
It's not a problem not to understand these, as long as the scientific and technological level of your tribe is separated from other tribes, no matter what awesome tactics you have, Lao Tzu will directly rely on advanced weapons and equipment, perfect logistics force, and directly fight.
He didn't believe that he couldn't get these ancient ancestors who were still playing with stones, and if this didn't work, then he would be too dark on the faces of countless traversers.
Plane geometry is far more interesting than boring numbers, the combination of numbers and graphics, as if the public has opened a door to a new world, the wonder of the mathematical world, in these patterns, vividly displayed.
The symbols, as if they have magical power, attract everyone's attention, and Yang Hao's explanation makes them completely immersed in the world of mathematics.
For several days in a row, Yang Hao devoted himself to the cause of education, from calculating the area of a simple plane figure to the Pythagorean theorem, Yang Hao almost used a cramming method to rapidly increase the knowledge reserve of officials.
He doesn't need these people, he uses this knowledge flexibly, he just needs them to memorize these axiomatic theorems.
Over the course of a few days, the earthen wall used for teaching was scraped off layer after layer.
He even suspected that if he continued to use it like this, perhaps the wall would collapse before long.
The backward teaching tools seriously affected his performance, which made him very dissatisfied.
As knowledge becomes more and more complex, this teaching method can no longer meet Yang Hao's needs.
In the sighs and sighs of a group of knowledge-thirsty officials, Yang Hao announced that he had suspended teaching, allowing these officials to comprehend what they had learned during this time.
and ordered Shaoyan and Yin to arrange manpower to engrave the knowledge points of this period on bamboo slips with knives for the officials to review in their spare time.
And he himself began to research, new teaching tools.
A few days later, with the completion of a batch of shoddy bronze weapons from the Ministry of Industry, two carriages loaded with weapons drove out of Chang'an City and headed east.
Regarding the agreement with Youyou's family, before completely tearing his face, Yang Hao felt that it was better to try to maintain a superficial friendliness.
Although the tribe is developing rapidly, the time for it to gain a foothold is too short, and compared with those profound clans, there is still a gap in many aspects.
He hoped to take advantage of this honeymoon period with Dongyi to carry out large-scale trade activities with Dongyi, using inferior weapons and equipment, and some exquisite bronzes in exchange for the living materials urgently needed by Daqi.
For a large clan like the Youyi clan, the number of slaves is definitely a terrifying number.
