Now the Gan family and the Shi family have once again fallen into the kind of ancient masters who used to calculate that the earth is a ball, but there is no way to explain how humans should survive on the sphere when the earth is a ball, and how to ensure that the sphere does not drop them down!

After all, among these people, they had already crossed the equator and went to the southern hemisphere the last time, and naturally understood that there was no saying that they would fly out.

Therefore, the current situation is that these people racked their brains to think about what the situation is. Thanks to this, otherwise the Gan family and the Shi family would have to squat together and some conflicts would break out. However, the current situation of completely lacking intent will not solve any problem even if everyone gathers together.

At most, it can make the Gan family feel more at ease - it turns out that the Shi family has no vision. Our Gan family needs to invest vigorously in this aspect. This is a great opportunity for us to surpass the Shi family and lay the foundation for the first family of the astronomical calendar. Everyone in the Gan family thought about it!

Of course, after seeing the situation of the Gan family, the Shi family felt a little relieved. It turned out that the Gan family had no clue. When our Shi family was looking for directions to burn resources vigorously, it was a great opportunity for God to surpass our Shi family and lay the foundation for the first family of the astronomical calendar. All the old and young people in the Shi family started to mobilize me!

Driven by this thinking pattern, two families who have been fighting for almost a thousand years. Well, these two families were still one thousand years ago. Anyway, the two families that started fighting since they split up and changed their surnames, after seeing the other party's status, all of them had an additional buff with increased intelligence.

However, even if we add this thing, both sides are confused and even have a little too much to explode. At most, the leaders of the two companies are feeling guilty, but they keep our X family winning the crown sooner or later, and you get out quickly.

But after all, after all, after fighting for so many years, no one knows who, and I held my breath, the old men of the two families could not maintain their previous momentum because they really couldn't figure it out.

"What the hell is going on?" The Gan family's master was rubbing his beard, and from time to time, he broke several of them, but he knew nothing.

"Why didn't we fall?" The old man of the Shi family 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 the attraction?" a young man said in a low voice.

"Hey, this makes some sense." Both the Shi family and the Gan family agreed, most afraid of having no answer at all. It is easy to study with a specious direction, but they are afraid of having no direction.

"Shi Tao, get up and talk, tell me what you think." The old man of the Shi family called out directly, and his momentum was completely different from before, with the demeanor of our Shi family taking the lead.

"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 changes on the sphere from Moling to Chang'an are really in the direction of the downward direction, then we should have gone down long ago." Shi Tao quickly stood up and explained.

Because the Central Plains is very wide, and the two families are still far apart, by the way, they are very far away from each other, regardless of north or south, as a pure ball, the distance between the two families on the sphere has been sufficient to show a large degree of arc change.

Therefore, if we infer from this aspect, if they did not fall down, there must be external forces, so the current problem becomes how external forces come about.

"Well, it makes some sense." The old man of the Shi family touched his chin, feeling very proud, and then gave his enemy, the old man of the Gan family. Not only did the two families fight themselves, but they also like to fight with their descendants, which is a comprehensive fight.

The old man of the Gan family felt stuffy at that time and turned his head to give his junior a look. Someone stood up on the spot. This was related to the face of their Moling Gan family.

How could it be that the Shi family was provoked and refused to be beaten back? Therefore, a few young people with a little immature mind and thoughts stood up on the spot. Our Gan family is not a vegetarian!

"The problem of spherical changes is actually only one aspect. In fact, from the dust and the various things we throw, we can see that the direction of these things is actually perpendicular to the earth, and the sphere is perpendicular to the intersection line of the earth..." A mathematician boss from the Gan family stood up on the spot. Those who do astronomy do not understand mathematics. Do you think they are joking?

"According to the trajectory of our throwing something, we can see that the direction of the force is vertically facing downward, not to mention that someone in our family has made parabolic arcs more than 10,000 times." Gan Fu kicked his cousin beside him, "His parabolic arc has calculated the rules!"

"Cousin, it's time for you to bring glory to our Gan family. I'll throw the calculation rules of different parabolas you made to the Shi family!" A group of people from the Gan family began to give the 25 or 26-year-old next to Gan Fu, who loves to throw stones and drift water, and for this, he throws stones every day. Then when he was fifteen, he suddenly wanted to study why the stones were thrown out and why it was like this trajectory, and why it would fly out when thrown at a small angle.

To be honest, if it were 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 has learned a lot of relevant mathematics knowledge for this, and the Gan family is not convinced.

After all, calendar, astronomy and mathematics are inseparable. Although Gan Zhen has a bad intention to learn mathematics, it is better to learn it as long as he learns it. It is better than being addicted to female sex when he is fifteen years old.

The subject of mathematics is good, and it is a subject of imputing the no-no-study subject. The Gan family said that they need to study hard and promote the home-study subject. It doesn’t matter if they are not good at it. As for imputing the no-study subject or not, it’s just a joke. Gan Zhen has reliable children.

There is no way. No matter how bad the Gan family is, it is a long-standing family. Can the younger generation who really work in their homes have no wives? Are you joking? Study it carefully. As long as you are a big boss, your wife will definitely prepare it for you when you were born and will wait for you to marry.

"After I lost tens of thousands of small balls, recorded their landing points and trajectories, and finally summarized them according to the degree and height of the force at the beginning, there is indeed a downward force, and this value should be a fixed value after comparing the weight, that is, we have been subjected to a force perpendicular to the place where we stand." Gan Zhen said that I really didn't lose those tens of thousands of stones in vain, especially the more I observed it later, the more carefully I looked.

"First of the ball!" Everyone reacted in an instant. There were no mixed fish in the group present. After saying the force perpendicular to the standing position, everyone came up with a result.

"We need a detailed experimental record, and what you call a fixed value, and how do you do your stress level?" Someone from the Shi family stood up and asked on the spot. They seemed to have discovered some more important things.

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

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

"It is the trajectory recording experiment of the collision of the small ball's swing arm." Shi Bao had already answered instead of Gan Zhen before Gan Zhen's answer. "A small ball of the same weight is used to exert force from the same height. There are a large number of records of this experiment at home."

Gan Zhen nodded. He did the same thing, and made many copper balls of the same weight.

"What conclusion did you come to?" Gan Zhen asked curiously.

"A rope of the same length swings while pulling the ball, the change in the mass of the ball has basically no effect. However, with the length of the line, the cycle becomes longer, and the length of the line becomes linear with the square of the cycle. I tried to calculate..." Shi Bao's mouth twitched twice, but it couldn't be calculated. Haha, Shi Bao said that he wanted to curse.

"In other words, we are all stuck in the downward power ratio. Is there any way to calculate it first? No matter why, let's try to see if we can calculate it?" Gan Zhen said solemnly.

"It is obvious that according to my trajectory, the ratio should be a fixed number. Although I don't know how this number comes from, we can redirect it by other means." Gan Zhen began to secretly instigate. In this kind of family, burning funds is simply a human habit.

But by this point, the Ganshi family no longer want to continue talking to each other. Why do you have to ask others to do what they can do? There is a lot of research data in our pile of paper, and now we just need to continue to burn money.

Once you have the direction, they are sure of burning money. Although they don’t know what the ratio is, they don’t care about it. If you calculate it first, as long as the process is in line with the process, the final result will definitely be logical, so it has reached this point...

Our Gan family does not need a slag like the Shi family. Let's go back and study the parabola of the ball, summarize the rules inside, first calculate the ratio of this mass to the additional power of the earth. As for why it is attracted, we will talk about it later.

The same is true for the Shi family. The Gan family is getting out of the junk. Our Shi family is preparing to study the issue of the cycle and line length inside the swing of the ball. At that time, the value inside will be pushed out, and then you will be beaten to death.
