- Looking at Gao Lu who was thinking hard, Liu Jin also laughed.
If he can study universal gravitation, then the field of physics in Ming Dynasty will open a new chapter first, turning the chapter of physics into the field of mechanics.
"Tell me, what on earth is he thinking about?"
Next to him, Zhu Houzhao obviously didn't want to continue discussing professional matters with Liu Jin. After all, in Zhu Houzhao's view, discussing these things with Liu Jin was like playing the piano to an ox.
So I started chatting with Ren Siheng on the side. Ren Siheng is also a genius. He has outstanding performance in many fields and has deep attainments in the field of mathematics.
"I don't know what he is thinking about. Could it be that if this pine cone is smashed on the head, it can make people enlightened and inspired?"
Ren Siheng thought for a while and shook his head slightly. To be honest, he couldn't figure out what Gao Lu was thinking about, but what was certain was that he must be thinking about something extremely profound.
"It's useless to ask you. Let's go and ask this Gao Lu together."
"I have long wanted to discuss calculus-related things with him."
Zhu Houzhao curled his lips, and then walked straight towards Gao Lu. Gao Lu's servants still had to stop Zhu Houzhao, but they were blocked by Zhu Houzhao's personal bodyguards.
Seeing Zhu Houzhao being so direct, Liu Jin and Ren Sisiu smiled, looked at each other, and followed him.
"Gao Lu, what are you thinking about?"
Zhu Houzhao came to the big maple tree, looked at Gao Lu, then looked at the people relaxing on the tree, and asked with a smile.
Gao Lu looked at Zhu Houzhao, Liu Jin, and Ren Siheng, but didn't pay much attention to them. Instead, he continued to frown and fell into deep thought.
"A little tempered~"
Zhu Houzhao didn't mean to be angry at all, and then followed Gao Lu's example and came to the tree.
The people on the tree stopped what they were doing when they saw Zhu Houzhao coming over.
"Keep playing, keep playing, I also want to see this pine cone hit on the head, it can make people enlightened from time to time."
Zhu Houzhao ordered to the people on the tree.
牺如 9bzw.com 牺如。 When the other party heard this, he thought about it and continued to put down the pine cones one by one. Soon, A pine cone fell on Zhu Houzhao's head. Zhu Houzhao touched his head and felt a little pain, but he didn't feel enlightened at all.
"You must be wondering why this pine cone fell on your head, right?"
Seeing the funny scene in front of him, Liu Jin laughed. He also came to the bottom of the tree and asked Gao Lu.
When Gao Lu heard this, his eyes suddenly shone with light, as if he had found a confidant, and said: "Yes, I was just thinking about why if I drop something from a height, it will fall to the ground, why won't it go up to the sky? Fly, or fall in other directions."
"Why did it fall to the ground?"
When Zhu Houzhao heard this, he immediately frowned, then thought about it and said, "Falling to the ground, isn't this the most normal phenomenon?"
However, soon, he frowned and said, "Yeah, why did it fall to the ground instead of flying up to the sky?"
"So you just let people keep putting fruit on your head and think about this problem again and again?"
"Well, one time I was reading under a tree and was hit by a pine cone. At that time, I was thinking why the pine cone hit my head and why it didn't fly up to the sky."
"Later, with the opening of new learning, we learned that we live on a big round ball. Since we live on a big round ball, it stands to reason that we are facing downwards, and we should be able to move from this big ball. It fell from above.¡±
"But in reality, not only will we not fall, but everything in the air will eventually fall to the ground. It seems that there is an invisible force that holds everything on top of this big ball. It¡¯s like it¡¯s absorbed.¡±
Gao Lu stopped, as if he had found a soulmate, so he also said what he was thinking.
¡°I really have never thought about this problem.¡±
"But when I heard you say this, I immediately felt that there must be some kind of truth in it."
"Yeah, why does everything on this big ball we live in eventually fall to the ground?"
After Zhu Houzhao heard this, he immediately frowned and started thinking hard.
"Yes, why?"Siheng listened carefully, frowning and thinking deeply, while the students around him who were watching the excitement were as if they were listening to heavenly scriptures, thinking that Gao Lu was talking nonsense.
What kind of gravity is it? Is this gravity related to mass?
"Haha, that's it, that's it~"
"It turns out to be because of something like gravity, the force of traction. Everything has gravity, and everything has gravity!"
Gao Lucai ignored what the people around him thought and thought, and thought carefully, while thinking about it, he kept saying new words one after another.
Then he said to his servant: "Bi Mo~"
When the servant heard this, he quickly took out a wooden board with rice paper on it. At the same time, he respectfully handed over a new pencil. Gao Lu took the pencil and began to write and draw on the paper.
The size of the gravitational force is related to the size of the mass. The gravitational force between two objects is related to the mass between the two objects, and it is also related to the distance between the two objects.
The mass should be proportional. The greater the mass, the greater the gravitational force. The smaller the mass, the smaller the gravitational force.
The distance should be inversely proportional. The smaller the distance, the greater the gravity. On the contrary, the greater the distance, the smaller the gravity.
He kept writing and drawing on the paper, and he came up with a formula, but he felt that it couldn't stop, so he tore off a piece of paper, and then started writing and drawing again.
"If you can calculate the mass of the earth and the moon, and then know the distance between the earth and the moon, you can calculate the gravitational force between the earth and the moon~"
"But how to calculate the mass of the earth?"
Gao Lu dragged his chin and fell into thought again. Mi He Mi
