Now the Gan Family and the Shi Family are once again caught in the kind of ancient elders who calculated that the earth is a ball, but there is absolutely no way to explain how humans can survive on the surface of the ball and how to ensure that the surface of the earth will not drop them. Go on!
After all, this group of people had already crossed the equator the last time and went to the southern hemisphere. They naturally understood that there was nothing to say about flying out.
So now the situation is that this group of people racked their brains to think about what the situation is, thanks to that, otherwise the Gan Family and the Shi Family must squat together for some conflict or something, but now this is completely unsightly The situation, bringing everyone together will not solve any problems.
At most, it can make the Gan family feel more at ease-the original Shijia group has nothing to look at, and our Gan family needs to invest heavily in this area. This is a good time for us to surpass the Shi family and lay the first family in the astronomical calendar. Everyone thinks about me!
Of course, Shijia felt relieved after seeing the situation of the Gan family. It turned out that the Ganjia group did n’t have any eyebrows. When we Shijia found directions to burn resources vigorously, this was the way God gave us the Shijia to surpass the Gan family. To lay a good time for the first family of the astronomical calendar, all the old and young people of the Shi family mobilized me!
Promoted by this mode of thinking, the two people who had been fighting for a thousand years, well, these two families were still a thousand years ago. Anyway, the two families who started fighting after they changed their surnames after seeing each other. After the state, all of them have a buff that strengthens their intelligence.
However, even if this thing is added, both sides are confused, and even some heads want to explode, at most, the two leaders are guilty, but the face holds that our X family will get the laurel sooner or later. Look.
But after all, after so many years of fighting, who didn't know who, suffocated, and not long after, the two old men couldn't maintain their previous momentum, because they couldn't make it out.
"What the is going on." The Gan family gurgled his beard, and from time to time several of them were cut off by himself, but he knew nothing.
"Why haven't we fallen?" The old Shi family is also irritated. According to the shape of this ball, the terrain of the Central Plains should have collapsed from north to south.
"Is it because of attraction!" A young man whispered.
"Eh, this makes sense." Shijia and Ganjia both agreed. They were most afraid that there was no answer at all. There was a plausible direction that could be studied, so I was afraid that there was no direction.
"Shi Tao, get up and talk and talk about what you think." The old man of the Shi family named directly, and the momentum was completely different from the previous one, which is much like our Shi family.
"Now we have calculated that this thing at the foot is a ball, and we have measured it several times. In fact, the change from Moling to Changan on the surface of the ball. If it is really a downward direction, then we should have long ago Go down. "Shi Tao quickly got up and explained.
Because the range of the Central Plains is very wide, and the two are still far away. By the way, whether they are north or south, or things are very far away. As a pure ball, the distance between the two of them running on the ball is enough. The degree of radian has changed.
Therefore, if it is inferred from this aspect, if they did not fall, there must be a reason for external forces. Then the question now becomes how the external forces come from.
"Well, it makes a little sense." The old man of the Shi family touched his chin very proudly, and then gave his enemy, the old man of the Gan family, a glance. The two families not only fight by themselves, but also like to pull their descendants to fight. Bucket.
Grandpa Gan's chest was stuffy at the time, and he turned his head to give his junior a look. Someone stood up on the spot, which was related to their face in Ganling.
Isn't there a reason why they were not provoked by the Shijia, so there are a few young people with a little immature idea on the spot, and we are not vegetarians!
"The problem of sphere change is actually only one aspect. In fact, we can see from the dust and various things we throw. In fact, the direction of the force of these things is actually perpendicular to the earth, and the sphere is perpendicular to the intersection of the earth. … "A mathematician at the Gan family stood up on the spot. The astronomical ones didn't understand mathematics. Do you think that was a joke?
"According to the trajectory of something we lost, we can see that the direction of the force is vertically downward, not to mention someone in our family has made a parabolic arc more than 10,000 times." Gan Fu kicked his cousin, "His parabolic arc calculated the law!"
"Cousin, it's time for you to win glory for our Gan family. Throw the 10,000 different parabolic calculation rules you made to the Shijia group of bastards!" A group of Gan family people began to give the twenty-five At the age of six, I love throwing stones and playing in the water. For this reason, I throw stones every day. Then at the age of fifteen, my brain suddenly twitched to study why the stones were thrown out and why they flew out of such a trajectory Gan Zhen who can fly out.
To be honest, if this average person was already defeated by reality, but because he was born in the Gan family, this guy is still alive and well, and he has learned a lot of relevant mathematics knowledge for this, and the Gan family also has this Not sure.
After all, calendar and astronomy are inseparable from mathematics. Although Gan Zhenmang has a bad purpose in learning mathematics, as long as learning is good, it is better than 15-year-old brains to start to indulge in female sex.
The subject of mathematics is good, the subject of an orphan, Gan Jia said that he needs this kind of hard work, the guy who promotes family learning, it does n’t matter what bad intentions, as long as it is really researching, as for the orphan. , Just kidding, Gan Zhen has reliable children.
No way, the Gan family can't do it anyway. Fortunately, it is a long-established family, so that the juniors who can really work in their own families have no wives? Joking? Study carefully, as long as you are a big brother, your wife must be ready for you when you were born, waiting for you to marry.
"After I dropped the ball tens of thousands of times, record its falling point and trajectory, and finally summed it up according to the difference in the degree and height of the initial force, there is indeed a downward force, and this value should be compared with the weight. It is a fixed value, that is to say, we have been subjected to a force perpendicular to the place where we stand on the ground. "Gan Zhen said that I really did not throw those tens of thousands of stones in vain, especially the more carefully I looked at it from the back.
"The heart of the ball!" Everyone responded in an instant, and there were no fishes in the crowd. After saying the force perpendicular to the standing position, everyone pushed out a result.
"We need a detailed experimental record, and what you call should be a fixed value, and how exactly do you work?" Someone from the Shijia stood up and asked, they seem to have found something more important. .
"I lost it at first, but later I lost it with the same power." Gan Zhen explained very solemnly. At this time, everyone actually noticed that this force is directed to the center of the ball, and if it is All directions, then it can explain why it is a ball.
"Same strength?" The Shijia family frowned and looked at Gan Zhen.
"It is the trajectory recording experiment of the small ball swinging arm collision." Shi Bao replaced Gan Zhen before Gan Zhen answered. "The ball of the same weight is used as the force, and it is from the same height. This experiment is at home. A lot of records. "
Gan Zhen nodded, he did so, and made a lot of copper of the same weight.
"What conclusion did you draw?" Gan Zhen asked curiously.
"The rope of the same length, holding the ball to swing, the change of the ball's mass basically has no effect, 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 After a moment ... "Shi Bao's mouth twitched twice, and it didn't count. Hahaha, Shi Bao said he wanted to scold others.
"That is to say, we are all stuck at the downward force ratio. Is there a way to calculate it first, no matter why, let's try to see if we can calculate it?" Gan Zhen looked solemnly. Said.
"Obviously, according to my pile of trajectories, the ratio should be a fixed number. Although I don't know how this number came from, we can push it back in other ways." Gan Zhen began to sneak in Now, in this family, what kind of money is burnt is just a matter of human nature.
But when it comes to this step, the Ganshis and I do n’t want to continue talking to each other anymore. Why do n’t you ask someone else to do what you can do? There is a lot of research data in our paper stack. Now you only need to continue to burn money. .
With the direction, they are still sure of what they are burning. Although they do n’t know what the ratio is, but let ’s figure it out first. Mathematics, as long as the process is opposite, the final result will be considered. It is contrary to common sense, it is absolutely logical, so this step ...
We Gan family don't need the scum of the Shi family. We walk around, we go back and study the parabola of the ball, sum up the laws inside, first calculate the ratio of this mass and the additional power of the earth, as to why it will attract, then talk about it later.
The thinking of the Shi family is also the same. The garbage Gan family hurries quickly. We Shijia are going to study the period and line length in the swing of the ball, and then push back the value inside to blow away your Gan family.
So the two, under the leadership of their elders, had a fight with each other and succeeded, and then rushed back to start burning money to conduct experiments, preparing simple and rough formulas based on large amounts of data.
