The atmosphere in the room was eerie, two men were looking at a woman's hairpin, a man and a eunuch to be exact.

Hu Ye looked at Ruan An curiously, this dead eunuch actually got a hairpin for a woman, there must be a woman in the palace.

Ruan An was playing with the hairpin with one hand and looked at Hu Ye at the same time, as if to let Hu Ye guess what he had realized.

In the end, Ruan An didn't hold on, and after Hu Ye stared at him with strange eyes for a while, he still handed the hairpin to Hu Ye, and said solemnly, "Boy, look at this hairpin, these two petals are connected together by an elastic wire." ”

"So what?" Hu Ye continued to look at Ruan An strangely, although he had never played with hairpins, he still knew the most basic structure, but he didn't know why Ruan An told him this.

"I think it's this elastic wire that gives these two hairpins to Newton, so that these two petals can open." Ruan An said very proudly.

Hu Ye was a little surprised when he heard this, although Ruan An didn't have the concept of strength now, but he could explain it in Newton, which showed that this thing was really good at thinking.

"Of course I know, my master said, there is a Newton's storage between everything, just like I am talking to you, there is a Newton's storage, and there is naturally a Newton's storage between these two hairpins and this wire. Could it be that you came to me today just to show me that you found Newton in your hairpins? Hu Ye glanced at Ruan An and said very unscathed.

"You are what I am, such an obvious thing, how could I come to you. I came to you today because I found that it is possible to represent the size of that newton with a hairpin. Ruan An said with a hint of excitement.

Hu Ye was shocked, this dead eunuch wouldn't have found a unit of strength so quickly.

"Hey, you see, when I pinched the clip, this wire had Newton on the two hairpins. As the hairpin opens the chengdù larger. Newton, the larger. So I thought that the size of Newton could be represented by the hairpin opening Cheng dù. ”

"For example, when it is opened to such a distance, it can be expressed in one newton." As he spoke, Ruan An pinched the hairpin open for a certain distance.

"When it is opened to this kind of chengdù, it can be expressed in terms of two newtons."

……

"When it is opened to this kind of chengdù, it can be expressed in ten newtons."

"How about it, our family is genius enough, how is it compared to your master?" Ruan An seemed to be a person who had discovered a new continent, and said to Hu Ye very excitedly.

Hu Ye looked at Ruan An blankly, and found that the head of this dead eunuch was really different from ordinary people, and his idea was to be more unique. I have already thought of using the system to measure the magnitude of the force. But this thing was done by the ancients a long time ago, and that's how these units came about.

So in essence, Ruan An has only advanced a little bit in the understanding of mechanics this time, and there is still a long way to go, because he has not yet realized that the action of force is mutual.

"Gonggong Ruan, your discovery is indeed very good, but you have considered that it was you who pinched this hairpin with force, so you specifically applied Newton to the hairpin. Or did the wire put Newton on the hairpin? And when you pinch the clip, do you also feel Newton's storage in your hand? Hu Ye said to Ruan An, this is a talent, maybe with his own help. He has a long way to go to become China's Newton.

When Ruan An heard this, he pinched the hairpin again, and found that it was really the same as what Hu Ye said. Suddenly, his face changed.

Then he took the hairpin into his arms and pulled the arm of his left hand with his right hand, letting out a roar.

Hu Ye looked at Ruan An in a daze. Even if it is a failure, you don't have to be so masochistic, right?

"It's strange why when I pinch the hairpin, I can feel Newton's storage. But when pinching oneself, only the arm of the left hand can feel Newton's deposit, but the fingers of the right hand cannot? Ruan An didn't pay attention to Hu Ye's strange eyes, but talked to himself.

"The magic barrier, the magic barrier." Hu Ye looked at Ruan An, who was talking to himself, and knew that this thing had now fallen into deep thinking about mechanics.

Hu Ye really wanted to help him completely understand the principle of force, but he was only a half-student, and he had long forgotten the knowledge of mechanics, so he knew that the unit of mechanics was Newton, and there were only so many people who could help Ruan An.

"Boy, do you know why? Am I wrong to use the hairpin to measure the size of Newton? Ruan An pinched himself and asked Hu Ye suspiciously.

"Grandpa Ruan, there's nothing wrong with your method, but it's too restrictive, it's like putting a bird in a cage, it can't spread its wings and fly." Hu Ye enlightened Ruan An, after all, if you want to make achievements in this area, you can't be bound by inherent thinking.

It's like if you say that the earth revolves around the sun, you will probably drown in the spittle of scholars all over the street, because they think that the earth is the center, the earth under their feet is the center, and everything else revolves around the earth.

"Hey." Ruan An listened to Hu Ye's words, and remembered the purpose of his trip, and couldn't help but be a little disappointed.

"Grandpa Ruan, there must be a road in front of the roadway mountain, and you will find the magic of Newton in the future, and it will also let you walk further in the building, and you will build better buildings for the Ming Dynasty." Hu Ye comforted Ruan An.

"Okay, I won't bother you anymore, you can review it well, the emperor is very optimistic about you." Ruan An put down his disappointed look and prepared to go out, and said as he walked, "I hope you don't pass the exam, so that you can come to the palace and study Newton with me every day." ”

Ruan An walked out of the door as he spoke, and the angry Hu Ye stomped his feet in the room. Sure enough, this dead eunuch didn't have a good heart, and now he still wants to let himself enter the palace as his apprentice.

"Young master, young master, I found that copper coin." As soon as Ruan An walked out of the door, Lao Qian ran into Hu Ye's house excitedly, waving a copper coin in his hand, and said happily to Hu Ye.

Hu Ye was in a very bad mood now, he just squinted at Lao Qian, then stopped talking, came to the table, and prepared to start reading, studying the exam papers of recent years, and seeing the essence of Baguwen.

"Young master, isn't it just a copper coin, if there is one less, there will be one less, I will give this copper coin, you can teach me the art of divination, I really want to learn." Old Qian said unrelentingly.

"Xiaoqiang send-off!" Hu Ye got angry and yelled at Xiao Qiang.

Xiaoqiang is now drunkenly lying at Hu Ye's feet to sleep, Hu Ye screamed twice and didn't respond, so he kicked over.

Xiao Qiang reluctantly showed his two teeth towards Lao Qian, and pulled Lao Qian's trouser leg out.

Lao Qian knew that the trick of dead skin and face was useless to the young master, so he had to go out helplessly, and he still tried his best to figure out where the disappeared copper coin went.

In the next few days, Hu Ye didn't go out of the restaurant again, but honestly squatted in the guest room to study Bagu, figuring out Wang Wei's preferences, reciting the sentences in the four books, and seriously preparing for the next township exam.

Yin Changlong is a studious person, especially after living in the guest room, the learning environment has improved, and he is the same as Hu Ye, except for eating and going out of the room, he has always stayed in the room.

Saren and Tsing Yi were very bored, and the young master didn't need them to accompany him when he was studying, so he ran outside every day and took Xiaoqiang out to buy all kinds of snacks. After four or five days, Xiaoqiang gained a lot of weight, and he walked round.

Lao Qian was guarding Hu Ye's door inch by inch, he was very strange, the young master had been in Nanjing for so many days, why didn't any local forces come to the door, weren't they interested in the bounty of the bounty order?

It would be false to say that the local forces were not interested in the bounty, because every night several groups of people would want to rush into the inn and kidnap Hu Ye. But without exception, before he entered the inn, he was solved by Zheng Dahe's question.

So after a few days, the local forces knew that this kid was not easy to mess with, so they stopped and waited for the best opportunity.

So the days seemed to be peaceful, until the eighth day of the eighth month of August, the scholars of the entire inn were busy, because tomorrow is the day of the township examination, and today you must enter the venue in advance. (To be continued......)
