This famous twisted scale experiment simply uses the reflection of light from a mirror to increase the visibility of small gravitational changes, so that the subtle movements of objects and ropes may not be visible, but through the mirror to the opposite wall, everyone can see it. Pen, fun, pavilion www. biquge。 info

After introducing it, everyone knew that this thing could measure the gravitational force of everything, but they didn't know what it could do, only Wen Huanzhang's excited beard shook and shook, some wanted to see it, and some were afraid.

Zhang San saw that the rope and stick were not moving, so he asked Wen Huanzhang, "What does Mr. Wen think?" Do you need to check it? ”

Wen Huanzhang took a deep breath and said, "No need, you can start." ”

Zhang San looked at Wen Huanzhang and said, "Why don't you try it yourself." ”

Wen Huanzhang shook his beard and shook his head, Zhang San didn't force it, he took a hammer from Zhang Yuanba at the moment, and gently approached the egg, until the children saw the reflected light and understood the noise, and the hammer was at least five or six centimeters away from the egg bag. Zhang San took away the reflected light from the hammer mirror and returned to the position just now, and then Zhang San stretched out the hammer to the rice bag, and the same thing happened again.

Then Zhang San brought bricks, stones, coals and other things to try one by one, the children looked at it with novelty, the adults talked about it, Zhang San stopped and motioned to Hu Ge to take the children to try it one by one. Nurture their hobbies.

Zhang San found Wen Huanzhang, who was distracted, and asked, "How is it, Mr. Wen?" ”

Wen Huanzhang felt very chaotic in his mind at this time, and the whole person seemed to be drained of his spirit, looking at Zhang San and arching his hand: "Wen is unwell, say goodbye!" ”

Zhang San looked at Wen Huanzhang's appearance and knew that this matter hit him hard, and he didn't force him to stay, so he asked Li Si to send him home at the moment. Li Si left with Wen Huanzhang with a lantern. Zhang San looked at his back in distraction. Yang Tai leaned in and asked, "What's wrong with this Mr. Wen?" ”

Zhang San looked at him with an evil smile and said, "Soon you will know." ”

Yang Tai looked at Zhang San's smile and had an urge to run away, but he didn't dare to leave quickly. Zhang San said to himself: "Will you come back?" ”

In the evening, Zhang San called Yang Tai, Li Si and others, everyone sat together, Zhang San mentioned the matter of Lu Bu and Leng Qingqiu, Zhang San meant to do his best to take in some orphans and teach literature and martial arts. They are no longer allowed to beg on the streets to avoid being exploited by bad people, who have been the most vulnerable since ancient times, either by abducting and selling, forming gangs of thieves, or begging with their hands and feet broken.

So Zhang San wanted everyone to come up with ideas, and he also listened to everyone's opinions. Everyone looked at each other, and first Li Si said: "Third brother, it's good that you have this heart, but there are regulations in the imperial court, and those who gather to perform martial arts without permission may be slandered and accused of rebellion." ”

Zhang San was very strange when he heard this, so he asked: "As far as I know, many granges and Haoqiang's families have martial arts teachers who gather to perform martial arts, why don't you see anyone report rebellion?" ”

Li Si said with a smile: "Most of the teachers invited by Haoqiang's family are to teach Zhuang households to practice martial arts and self-defense, and the nursing homes at home have also been reported by the government. In addition, there are some township groups and other organizations. ”

Zhang San thought that this was indeed a trouble, and after thinking for a while, he asked: "If I set up a private school to provide food and clothing for these children and teach these children to be civil and military." Is this okay? ”

Li Si thought about it and said, "It can be, but this ......"

Zhang San heard that it was okay to guide Li Si but what he said meant that he was afraid that he would be thankless, in fact, Zhang San didn't think so, these children have gone through their own education, learned the knowledge they imparted, and used the clothes and food they provided. In the future, you will definitely be close to yourself.

At that moment, Zhang San took a blank piece of paper and began to plan the appearance of the school, and Zhang San saw a lot of schools, nothing more than classrooms, canteens, dormitories, libraries, sports fields, etc.

With Zhang San's current ability, Zhang San plans to adopt one to two hundred children first, then a class of fifty people only needs four classrooms, six people in a room, thirty dormitories, the canteen does not need to be large, the sports field needs to be larger, and the football field must at least have it. There is still enough room for future development, and Zhang San plans to use 100 acres of land first.

At the moment, Zhang San told everyone about the plan, and everyone naturally would not object to Zhang San doing good deeds, although I don't know why Zhang San is like this, but everyone still put forward their own opinions, Zhang San patiently explained, for example, why the dormitory is divided into two yards, because Zhang San also plans to accommodate some girls, why build so many thatched houses, Zhang San said that it is for hygiene.

Seeing that everyone has no opinion, Zhang San thinks about this matter is still more important, and now Zhang San transferred Wu Decai out to be responsible for this matter, and the formula of sixteen incense was handed over to Liu Yun's father and monkey and his mother to be responsible, since Zhang San recruited Liu Yun over, he also took Liu Yun's father and sister by the way, after all, there are a lot of shadow puppet plays, but martial arts masters are still relatively lacking. Nolan is now working with Yifei to help Sister-in-law Yang manage those girls.

Wu Decai was also very happy when he heard this, although the production of sixteen incense is important, it is inevitable that dealing with these things every day is a little boring. You don't have to be trapped in the yard for this job.

Next, Zhang San was going to ask the monkey to inquire about the organizations that controlled the little beggars in the capital, but now that the monkey had not returned, he didn't know what progress he had made in finding out about Sun Li's news.

Zhang San looked outside the door and happened to see the monkey running back, so when he came to the main hall, the monkey said, "Third brother, I inquired." ”

Zhang San hurriedly said: "Rest first, don't worry, you speak slowly." ”

The monkey took a breath and said, "That Sun Li has been calling himself sick, and he hasn't gone to the Royal Boxing Gym, and he has been fighting in the back door bridge tiles on Jinglongmen Outer Street for the past two days. ”

Saying that, the monkey took two breaths, afraid that Zhang San would not know, so he explained: "The back door bridge tile is three or four streets east of our Yixing Hutchison. ”

Zhang San nodded and said, "Well, there is nothing else." ”

The monkey said: "I went to the back door bridge tile, and saw that he went to the Shandong Opera Museum several times to listen to the music, and after inquiring about it, I found out that he fell in love with a young lady who sang music in the Shandong Song Museum. ”

Zhang San listened, Zhang San was in no mood to care about this bullshit, as long as he wasn't looking for trouble for himself. said at the moment: "Okay, you have worked hard, tomorrow you don't care what little lady he is looking for, tomorrow you help me inquire, those people in Tokyo City are the leaders who control the little beggars to steal things and beg." I'll be of great use in the future. ”

The monkey nodded and said, "Hey, I know the third brother." That Sun Li is also a good blessing, that little lady looks so smart, just like what came out of the painting. The little lady was unwilling, but she couldn't stand him from having a younger brother who loved guns. In order to let Sun Li teach him a gun, his sister ignored it. This young man sings so well, what kind of gun and stick he learns, he is really blind to his name of iron called Zile He. ”
