Chapter 101 Put away your magical powers!

Qiao Youyou looked at everyone's reactions with satisfaction.

That’s right, that’s it. The more you don’t believe it now, the better the show will be later!

Come on, get a little Archimedean shock!

A cunning look flashed in her eyes, and she pushed the object wrapped in white cloth in front of her hard under the table.

As the rope became tight, the end of the log close to Qiao Youyou slowly sank, and a creaking sound of wood was heard on the field.

Everyone's face instantly turned into astonishment -

"Ah! Look! The statue of Confucius seems to be really moving!"

As the stone statue in front of Qiao Youyou, which was only half the height of the statue of Confucius, fell to the ground with a loud bang and dust flew everywhere, the three-meter-tall statue of Confucius on the other side was actually slowly lifted off the ground!

Moreover, it is still shaking slightly!

This stone statue has stood here since the establishment of Longchang Academy. It has experienced a hundred years of wind and rain and has never been shaken in the slightest.

Now, it was actually lifted up by a piece of wood! ?

"Qiao, Qiao girl... put away your magical powers!" Master Li was also frightened. If the stone statue of the saint fell down and broke, it would be a great sin!

Qiao Youyou looked around, enjoying everyone's astonished gazes.

A voice in the crowd shouted, "What's so strange about this? I weigh pigs the same way at home!"

His father was a pig farmer, and he would check the weight of the pigs every once in a while, but the weight he used was much bigger.

Master Li was so angry that he blew his beard and glared. What kind of analogy is this! ?

When the others heard this, they also recovered from their shock.

Yes, this scene looks shocking, but if you think about it, it is actually quite familiar.

Isn't it just a big scale?

Qiao Youyou smiled mysteriously, "I know what you are thinking."

She raised her arm, pointed at the hanging statue of Confucius, and asked everyone:

“What would happen if I moved the statue of Confucius further away?”

The students looked at each other, and some said hesitantly:

"According to common sense, the two sides should be balanced first. If they continue to move, the statue of Confucius will fall down, right?"

"That's right." Qiao Youyou nodded. "Then the next question is, where should we move to so that both sides can achieve balance?"

"This..." The student who had just answered the question was suddenly speechless.

He watched others weighing things, and they moved the weight as they watched. Whichever place it reached was balanced, that was it. Who could know in advance?

Qiao Youyou raised the corner of her mouth with a bit of pride. Although levers have been used in ancient times, the wisdom of the ancients was mostly summarized based on experience and phenomena, and they did not pay much attention to exploring the principles.

For example, the scales used for weighing are also marked by finding an object of standard weight and repeated experiments, and there is no accurate formula to calculate.

She pulled out a small scale from behind her like a magician, but the appearance of this scale was different from what people usually saw.

Someone asked curiously, "Why is the knob of this scale hung in the middle?"

Qiao Youyou took out two weights, one large and one small, and showed them to everyone.

"There are two weights now. The big weight weighs three taels, and the small weight weighs one tael.

I will now hang the small weight on the outermost end of the scale bar, one foot and two inches from the scale knob.

As Qiao Youyou spoke, she hung the small weight on the scale, and the scale bar immediately tilted.

"Then where should the weight be hung to balance the beam?"

The eyes of the audience were all a little confused. This kind of thing can only be known after trying it. How can it be said without any reason?

Qiao Youyou smiled slightly, "I can teach you now, if you want to balance the scale, you have to multiply the weight of the weight by the distance from the weight to the scale button, and the results on both sides should be the same.

The scale knob is set in the middle, naturally to ensure that the weight of the scale bars on both sides is equal, which makes calculation easier. "

The students seemed to be thinking about what was said and started counting with their fingers again.

Even Ouyang Ye and the teachers couldn't help but roll their eyes and think.

Qiao Youyou didn't expect that such a simple arithmetic would take them so long. He sighed and was about to reveal the answer when he heard a weak voice from the audience:

"Could it be... the four-inch area?"

"Okay! Let's give it a try." Qiao Youyou nodded and hung the small weight four inches away from the scale button.

The beam began to rotate, shook a few times, and soon maintained balance.

“It’s actually... a draw!” There were exclamations from the audience.

This method of calculation is so magical that it can get the result directly without any trial and error?

Qiao Youyou nodded with a profound look on her face, but she was very happy in her heart.

Although the lever principle belongs to the field of physics, mathematical calculations are also indispensable.

As long as she uses this as a starting point to arouse everyone's interest, she won't have to worry about no one being interested in the Mathematics Society!

Anyway, mathematics, physics and chemistry are inseparable!

Only then did Qiao Youyou ask Mr. Fang and the craftsmen to help lift the small stone statue in front of them and move it back to the platform.

The statue of Confucius slowly fell back to the ground, still in its original position, and everyone's hearts finally settled down.

"Senior Sister Qiao...what exactly is wrapped in there?" someone asked, still with a hint of panic in the voice.

Qiao Youyou pulled off the white cloth, revealing a bust of stone statue inside.

She asked Zhu Lan to draw a picture of Archimedes based on his impression from modern textbooks, and then had someone carve it.

A little creativity was also added by having the old man raise two fingers in front of his chest.

"Let me introduce you to everyone. This is Archimedes. He once said, give me a fulcrum and I can move the earth!"

There was confusion in everyone's eyes.

"What the hell? What a weird name..."

"Is this guy really not a monster? Why are his beard and hair all tangled? How can a human look like this?"

"What kind of ball is the Earth? Could it be heavier than the statue of Confucius?"

Qiao Youyou coughed twice and said to the audience:

"I can now reveal the secret to you directly. The algorithm I just mentioned is called the lever principle, which was proposed by Archimedes."

When everyone heard this, they looked at the stone statue with a bit of reverence in their eyes.

"Of course, such calculations are only a very small part of mathematics—" Qiao Youyou kept it a secret, "For more secrets, please join the Mathematics Club to find out."

"Okay, I'll join in! After I learn this, maybe I can help my dad weigh pigs in the future!"

“I’m joining in too!”

"And me!"

More and more students in the crowd raised their hands.

"Okay, okay, everyone line up and register your names!" Qiao Youyou took out a small notebook with a smile and started registering.

Zhu Lan, Liang Zhou and others all smiled when they saw that Qiao Youyou's experiment was a great success.

No one noticed that a slender figure quietly left here.

…

While everyone was watching Qiao Youyou's Mathematics Society, Ding Xiaoqiu quietly returned to the study.

Linfengyuan was empty at this time. Ding Xiaoqiu looked at the place where he had lived for more than two years, feeling mixed emotions.

All good things must come to an end, it's time for him to go.

After failing the college entrance examination, he suddenly found that he was not as sad as he had imagined.

He doesn't have the ability of photographic memory like Zhu Lan, nor does he have good grades like Liang Zhou who eats, drinks and has fun every day. Perhaps he is not cut out for studying.

When he entered Longchang Academy, he worked hard just to clear his father's grievances one day.

Now, with the help of Zhu Lan and Chang Yunxiao, my father has been cleared of all charges, and he has managed the county town very well. He has become a good official in the hearts of the people and realized his dream.

Ding Xiaoqiu thought about it and wondered what his ideal was.

In fact, he doesn't like studying that much.

Rather than studying, he preferred to immerse himself in the world of calligraphy and painting, and listen to his senior brother Liang Zhou tell him about things outside.

Liang Zhou said that in the north of the east, the winters are extremely cold, and the people there can build a castle with ice and snow that will not melt in the summer.

Liang Zhou said that on the other side of the Nanling Mountains, there are countless peaks rising from the ground in various shapes and forms, and the river meanders through them, clear to the bottom, and it is as beautiful as a painting.

Liang Zhou also said that in Senior Sister Xiao Wan’s hometown, everyone loves to eat dogwood hotpot and play a game called "mahjong". The men there love their wives very much.

Ding Xiaoqiu had never seen these things, and they were not even written about in books.

As the ancients said, read ten thousand books and travel ten thousand miles.

The world is so big and he wants to go see it.

In fact, after learning that he had failed the college entrance examination, Ding Xiaoqiu had already written a letter to his father to explain the situation. Ding Wangyuan not only did not reprimand him, but also comforted him.

It is said that the lychees in Lingnan are ripe again. They are as big as meatballs and pink and tender. Let him go and taste the freshest one, which is guaranteed to be sweet.

Ding Xiaoqiu has already planned a general itinerary and he plans to leave here quietly.

If he said goodbye in person, he was afraid that he would not be able to cope with such a sad scene.

Ding Xiaoqiu packed his bags, left a letter to Liang Zhou and Zhu Lan, his good friends who had helped him, and swept the entire study with clean water before reluctantly leaving Linfeng Garden.
