Mythical Version of the Three Kingdoms

Now the Gan family and the Shi family are once again caught up in the situation where the ancient masters calculated that the earth is a ball, but there is no way to explain the earth is a ball. How should human beings survive on the sphere, and how to ensure that the sphere does not drop them? go down!

After all, some of these people had already crossed the equator and been to the southern hemisphere last time, so they naturally understood that there was no such thing as flying out.

Therefore, the current situation is that this group of people racked their brains to think about what the situation is, and thanks to this, otherwise, some conflicts would definitely break out between the Gan family and the Shi family, but the current situation is completely useless However, bringing everyone together won't solve any problems.

At most, it can make the Gan family feel more at ease-it turns out that the Shi family has no clue. Our Gan family needs to invest heavily in this area. This is a great opportunity for us to surpass the Shi family and establish the first family of astronomy and calendar. The Gan family Everyone give me brains to think!

Of course, the Shi family felt relieved after seeing the situation of the Gan family. It turned out that the gang of the Gan family had no clues. When our Shi family looked for directions to burn resources, it was God who gave us the Shi family to surpass the Gan family. , It's a great time to establish the first family of astronomy and calendar, all the old and young of the Shi family will mobilize me!

Driven by this way of thinking, the two families who have been fighting for almost a thousand years, well, the two families were still one thousand years ago, anyway, the two families who have been fighting since they separated and changed their surnames, after seeing each other After the state, all have an intelligence enhancement buff.

However, even if this thing is added, the two sides are still at a loss, and even some heads want to explode. At most, the leaders of the two families are guilty, but on the surface they insist that our X family will get the laurels sooner or later, and you get out of here. look.

But after all these years of fighting, who doesn't know who, he held his breath, and after a while, the old men of the two families couldn't maintain their previous momentum, because they really couldn't figure it out.

"What the hell is going on here." The master of the Gan family stroked his beard, and broke a few of them from time to time, but he didn't know anything about it.

"Why didn't we drop it?" The old man of the Shi family also looked irritable now. According to the shape of this ball, the terrain of the Central Plains should have collapsed from north to south long ago.

"Is it because of attraction!" A certain young man whispered.

"Hey, this makes sense." Both the Shi family and the Gan family agreed, most afraid that there would be no answer at all, and it would be easy to study if there was a plausible direction, but they were afraid that there would be no direction.

"Shi Tao, get up and talk, and tell me what you think." The old man of the Shi family called his name directly, and his momentum was completely different from before. It seemed that our Shi family was a step ahead.

"In this situation, we have calculated that the thing under our feet is a ball. Moreover, we have measured it several times. In fact, if the change on the spherical surface from Moling to Chang'an is really a downward direction, then we should have Go down." Shi Tao hurriedly got up and explained.

Because the scope of the Central Plains is very wide, and the two families are still far away. By the way, they are very far away from north to south, or from east to west. As a pure ball, the distance between the two of them on the sphere is enough to appear very far The degree of curvature has changed.

Therefore, inferring from this aspect, if they did not fall, there must be an external force, so the question now becomes how the external force came from.

"Well, it makes sense." The old man of the Shi family touched his chin, very proud, and then gave his archenemy, the old man of the Gan family, a look. These two families not only fight on their own, but also like to pull their offspring to fight, which belongs to all-round bucket.

The old man of the Gan family felt tight in his chest at the time, and turned his head to give his younger generation a look. Some people stood up on the spot. This was related to the face of their Moling Gan family.

There is no reason not to fight back after being provoked by the Shi family, so a few young people with a little immature ideas stood up on the spot, and our Gan family is not vegetarian!

"The problem of the change of the spherical surface is actually only one aspect. In fact, it can be seen from the dust and the various things we throw. In fact, the direction of force on these things is actually perpendicular to the earth, and the intersection line of the sphere perpendicular to the earth ..." A big mathematician from the Gan family stood up on the spot. Those who engage in astronomy don't know mathematics, do you think it's a joke?

"According to the trajectory of some things we threw, we can see that the direction of the force is vertically downward, not to mention that someone in our family has done more than 10,000 parabolic arcs." Gan Fu kicked his cousin, "His parabolic arc has been calculated regularly!"

"Cousin, it's time for you to win glory for our Gan family, and throw away the calculation rules of 10,000 different parabolas you made to those bastards of the Shi family!" At the age of six, I love to throw stones and float in water. For this reason, I have to throw stones every day. Then when I was fifteen, I suddenly had a brain twitch and wanted to study why the stones flew out in such a trajectory, and why they were thrown on the water at a small angle. Gan Zhen who can fly out.

To be honest, if this is an ordinary person, he would have been defeated by reality long ago, but because he was born in the Gan family, this guy is still alive and well, and he has learned a lot of related mathematics knowledge for this, and the Gan family also agrees with this. Noncommittal.

After all, calendar, astronomy and mathematics are fundamentally inseparable. Although Gan Zhen's mad learning of mathematics has bad intentions, as long as he learns it is good, it's better than becoming obsessed with women at the age of fifteen.

Mathematics is a good subject. The subject of solitary students. The Gan family said that they need this kind of guy who studies hard and promotes family studies. It doesn't matter if he has bad intentions, as long as he is really studying. , Just joking, Gan Zhen has reliable sons and daughters.

There is no way, no matter how bad the Gan family is, it is a long-established family, and the younger generation who can really work in the family have no wives? Are you kidding me? Study hard, as long as you are a boss, your wife must have been prepared for you when you were born, waiting for you to marry.

"After throwing the ball tens of thousands of times, recording its landing point and trajectory, I finally concluded that there is indeed a downward force based on the degree of force at the beginning and the difference in height, and this value should be compared with the weight. It is a fixed value, that is to say, we are always subjected to a force perpendicular to the place we stand on the ground." Gan Zhen said that I really didn't throw those tens of thousands of stones in vain, especially as I observed more carefully as I went to the back.

"The center of the ball!" Everyone reacted in an instant. There was no miscellaneous fish in the group present. After telling the force perpendicular to the standing position, everyone came up with a result.

"We need a detailed experimental record, and what you said should be a fixed value, and how did you measure your stress?" Someone from the Shi family stood up and asked. They seemed to have discovered something more important. .

"In the beginning I threw it casually, but later I threw it with the same force." Gan Zhen explained solemnly. At this time, everyone has noticed one thing, that is, the force is directed at the center of the ball, and if it is All directions, then it can explain why it is a ball.

"Same power?" The Shi family frowned and looked at Gan Zhen.

"It's a trajectory recording experiment of the impact of a small ball swinging the arm." Shi Bao had already answered Gan Zhen's place before Gan Zhen answered, "A small ball of the same weight is used as a force, and it is enough to exert force from the same height. I have this experiment at home. Lots of records."

Gan Zhen nodded. He did the same thing, making a lot of copper balls of the same weight.

"What conclusion did you draw?" Gan Zhen asked curiously.

"With the same length of rope, the change of the mass of the ball has basically no effect on the swing of the ball, but with the length of the line, the period becomes longer, and the line length is linearly related to the square of the period. I try to calculate For a moment..." The corners of Shi Bao's mouth twitched twice, unable to figure it out, hahaha, Shi Bao expressed that he wanted to curse.

"That is to say, we are all stuck at the downward power ratio. Is there any way to calculate it first, regardless of the reason, let's try to see if we can calculate it?" Gan Zhen looked solemnly. Said.

"Obviously according to my pile of trajectories, that ratio should be a fixed number. Although I don't know how this number came about, we can reverse it in other ways." Gan Zhen began to secretly tease Speaking of which, in this kind of family, burning money is simply a kind of human nature.

But at this point, the Gan and Shi families don't want to continue talking with each other anymore. Why do you need others to do what you can do? Our family has a lot of research data in the pile of paper, and now we just need to continue to burn money. .

With the direction, they are still sure about burning money and so on. Although they don’t know what the ratio is, but whoever it is, calculate it first. For things like mathematics, as long as the process is correct, the final result will be fine. It is against common sense, and it is absolutely logical, so at this point...

Our Gan family doesn’t need such scum like the Shi family. Let’s go back and study the parabola of the small ball, summarize the laws inside, and first calculate the ratio of this mass to the added force of the earth. As for why it is attracted, we will talk about it later.

The same thinking of the Shi family is the same, the garbage Gan family should get out of here, our Shi family is going to study the cycle and line length in the swing of the ball, and then reverse the value inside, and blow you Gan family to death.

So the two families, under the leadership of their respective elders, had a fight with each other, and they broke up successfully. Then they rushed back and started burning money for experiments, preparing to simply and rudely reverse the formula with a large amount of data.
