In the study of things, Yang Heng originally thought it was a very easy lesson, but it was just physics in his previous life. But when he stood in front of everyone, he suddenly realized that this was a very difficult problem. If people at this time did not know any knowledge of studying things, it would be fake, but if they knew it, it would be fake.

How to explain this? It seems to be a bit contradictory, but you will know that it is not contradictory by looking at the following examples.

"You have all hunted, have you?" Everyone thought that Yang Heng, the boss, was going to ask them what they were talking about, but they asked such a topic: hunting, who has never hunted? When there is not enough food, and when there is still people who are forced to be bandits and have no food, they have to come and hunt, but hunting is a variety of things.

"I have used arrows to shoot prey," "I have dug traps, caught prey with traps, and caught wild boars." "I have practiced throwing stones and hitting small prey with stones."...

There are many ways to hunt, but to sum it up, there are only two methods, one is the long-range attack method and the other is the ambush method.

"Okay, don't talk about these ways to dig traps and put condoms. Let's talk about shooting arrows and throwing stones. Tell me, did you directly aim at the prey when you are catching active prey?"

"No, no, the boss is just the boss. I don't even know how to hunt. I really enjoy my happiness." Everyone started talking nonsense. Some people even envied Yang Heng as the boss. What does this have to do with whether he could hunt? You will never catch up with the prey I hunted in your life, but Yang Heng was not here to be angry. Instead, he wanted to explain some things.

"Okay, how did you hunt?" "I." I'm still scratching your itchy flesh, isn't it just a hunting thing? You're so proud, this man was so proud that he was talking about his glorious history. "When I was hunting, I couldn't catch it, why couldn't I catch it? It's because I kept hitting the prey's body. Think about it, the prey was running. Don't say it was running sideways, just

I ran along, but I couldn't hit it, until one time I asked an old hunter. He explained a truth to me. Just when the prey ran, as long as you aimed at the front of its head, it would be easy to catch prey. In this way, I caught more prey, basically I encountered ten preys, and I could hit one or two of them." He looked around proudly, as if he was a general. Then he sat down.

"Where are you?" Yang Heng asked another person again, and the person looked a little guilty. "I, I, only five preys, have two or three. How did I hit it? I used stones to hit it, but at first I couldn't hit it, but later I accidentally discovered something, which was to catch the front of the prey, so that the prey would basically not run away, but some preys cannot be killed by one stone. When I hit it, when I went over to pick it up, it would get up and run away. If I had a bow at that time, it would be great."

"Gaga," I don't know which mountain secret guard accidentally alarmed the bird, and Yang Heng had an idea. He heard that the bird was flying over his head, so he put on a hand and threw a stone in his hand. As a result, a stone hit the bird down. Let you make fun of me, "Tonight I'm talking about investigating things. Don't talk about how mysterious it is. First of all, I asked you, hunting is a kind of investigating things, that is, kinematics. Do you know why you should hit the front of the head of the prey in sports? This is a profound question, and the bird I captured. Do you know what the problem is? It's about listening to sound and distinguishing the direction..."

Starting with interesting things, or even from things closely related to people, you will achieve unexpected results. This lesson is very successful because everyone has gone through difficult times. If you encounter them again, you may be able to use hunting to maintain your life.

"Did you all understand?" "I understand. Master, you said that if we take action quickly enough, we can directly aim at the prey. Even if we aim slightly at its head, the more we need to go ahead. But Master, we have another question, that is, when the arrow is far away, why would the arrow fall down in a curved route?" Unexpectedly, he didn't expect that although these people were not well educated, they would learn from it.

"Is this? You have to take the apple. At this time, it's not called an apple. Then it's the ones that are red in the mountains. You have to talk about it. If the fruit is ripe, it will fall down. It will hit your head, right?" Yang Heng pretended again. This time it made sense. I will take over the story of the fall of this apple first. It depends on how your surname Niu will make the apple slam the head. But Yang Heng was wrong. This apple may continue to hit the head of Niu, or he will continue to come up with an apple slamming the head. Perhaps more than a thousand years later, China will argue with the West. Whose head was hit by this apple first? Or maybe a bastard country that is not a bastard country is fighting for its own credit. The person who was hit by the head by the apple in history is from our bastard country. This will eventually become a dispute case.

"Fruits hit the head, and the fruit will fall off when it ripens. And when the fruit falls, won't you avoid it? Do you like to be hit on the head by ripe fruits?"

Everyone started talking nonsense again. They were not afraid of Yang Heng, the boss. Yes, Yang Heng usually laughed and laughed, so naturally they would not be afraid. They were afraid of the housekeeper.

"Why? Brother Heng must have his reason. Is this like shooting an arrow. The arrows fall to the ground, and the fruits fall to the ground, but not to the sky. However, everything in this world falls to the ground, but I didn't see the past falling to the sky. By the way, the smoke and dust seem to float to the sky, which can be considered falling to the sky, right?" At this time, not only Xiao Niang, but Changle and Yu Zhang were also frowning and thinking, and even nodding at Xiao Niang's words, so everyone also started to think.

"I'll tell you this. For you, it's still difficult to understand. But I still want to tell you that I gave this phenomenon a name called gravity, which means that the earth can attract anything, that is, the smoke and dust that Xiaoniang just mentioned will be attracted by gravity in the end."

"The boss, why is it called universal gravity? It's not possible to call it 100 gravity, or it's called Qianyou Gravity." Yang Heng found that these people would not be able to beat them up without being beaten, and he actually started to tease the boss. This is great. What else can I have in the future? Prestige, but how can I scheming them? I really can't do it. Is it better to kill people and demonstrate, and I can't beat a hundred killing sticks, but I just talk and laugh, how can I hit someone's sticks? I'd better do this first, so that I don't seem more popular.

"Okay, okay, don't discuss it, it's called gravity. It's the name given by a man named Niu from the distant West. If you don't accept it, I'll let the emperor issue an imperial edict, and then it's called gravity. If the person surnamed Niu doesn't mention it, we will snatch his first. Okay, that's it. What, you don't understand, is it easy to understand? You two people hold hands and retreat each other. By the way, is there a great pulling force? This gravity is the hand of the earth, which pulls your body as a whole, or even any object on the ground. This is called gravity. I don't understand. When the fruit is ripe, you sit under the fruit tree and let the fruit smash the head and hurt it for hundreds of years. You may understand." You make fun of me, and I'll make fun of you.

"Okay, let's review it, today..." (To be continued...)
