Daiyu: After being reborn, who still wants to be a yandere?

Chapter 30 No Need to Underestimate Yourself

When other students in the class heard Liao Qiuxia say this, they were also a little confused.

Although we are all liberal arts students, it is now the 21st century. Who among us has not read a few encyclopedias or "100,000 Whys" when we were young?

I just haven't seen it. After all, they have taken the high school entrance examination. Even if they failed the physics test, there would be all kinds of popular science propaganda in the cartoons.

So, you must know this most basic principle of concave lens.

Many students looked at Daiyu with puzzled expressions.

The history teacher was also a little confused.

Liao Qiuxia's face was full of mockery at this time. She knew that it was useless to have only good looks but no inner talent:

"Student Lin, should we ask Zheng Yan from the science class to give you a brief introduction to the principles of concave lenses?"

When Yang Liushu heard Liao Qiuxia mention Zheng Yan, he felt a little unhappy. Zheng Yan, the science nerd who looks down on others, isn't this boosting others' ambitions and destroying the prestige of her own class?

He advised:

"Qiuxia, let's talk it over nicely. Sister Lin hasn't even told you the reason yet."

The history teacher saw that the atmosphere in the class was a little tense. Everyone was discussing physics in history class. He didn't know whether to be sad or happy. He waved at Daiyu:

"Student Daiyu, can you elaborate on the confusion?"

Daiyu was not in a hurry either. She just said:

“Ancient people said that Yang Sui can make fire, and Fang Zhu (Yin Sui) can make water.

The earliest fire-making method using Yangsui was invented in the Western Zhou Dynasty, more than 3,000 years ago. It was a tool for making fire invented by our ancestors in the Bronze Age of ancient my country using the principle of solar concentration..."

The history teacher suddenly looked up, his eyes full of surprise. As a history teacher, and having taught for so many years, he certainly knew about the ancient Chinese method of making fire by using a yangsui.

However, he never combined the use of solar fire to make fire and Leonardo da Vinci's use of solar energy.

Daiyu's words shocked the history teacher. He usually taught students to play with mobile phones less, especially not during class.

At this point, he had already convinced himself and silently took out his cell phone to search on Baidu.

Liao Qiuxia didn't want to listen to Daiyu talking about the fire-making method with a sun flint or the ancient Chinese metaphysics. To her, it was not science. She interrupted Daiyu directly:

"Haha, Mr. Lin, you are wrong. It was Leonardo da Vinci who first proposed the idea of ​​using solar energy. Foreign science and technology are far ahead of our country."

After that, in order to prove that her judgment was correct, she walked to the desk, opened the history textbook, and said to all the students:

"If you open your history textbooks, you will know that this is what is written in the books. It was the Renaissance at that time."

Some students did not understand what Daiyu said, and followed Liao Qiuxia's lead:

"Yes, Qiuxia is right."

Daiyu raised her eyebrows slightly and said:

"I haven't read the books. I don't know anything about the Renaissance."

Doesn’t she know about the Renaissance?

When Daiyu said this, even the history teacher who was using Baidu almost dropped his jaw in shock.

No, to understand the origin and development of the Renaissance and its impact on European society, culture and politics -

Isn’t this the basic quality of a liberal arts student?

When Liao Qiuxia heard Daiyu say this, the corners of her mouth curled up with a hint of mockery:

"So, it's useless to just put on makeup and be beautiful. People still need to learn knowledge and improve themselves both inside and out, so that they can contribute to society."

After saying this, she even touched the hairpin on her head, trying to put on the image of a classical talent.

Daiyu nodded repeatedly and said with a smile:

"I am indeed a cultural idiot and I am not good at studying."

Liao Qiuxia said:

"It is very valuable that Mr. Lin knows this. We should have the attitude of never giving up and never giving up."

Daiyu continued to ask seriously:

"So I'm quite confused, the Western Zhou period roughly began in 1046 BC and ended in 771 BC.

Leonardo da Vinci was born in 1452.

So why is it said that 'he was the first to propose the use of solar energy and planned to use concave mirrors to boil water through solar energy'? "

At this time, the history teacher had finished searching on Baidu, and combined with what Daiyu said, he suddenly had an epiphany.

Liao Qiuxia couldn't listen any longer, she coldly rebuked:

"So, what do you want to say, Lin? That's what our history textbooks say. Western science is more advanced than ours. Are you trying to brainwash us with these feudal superstitions?"

Daiyu paused and continued:

"It's okay. I just want to say that the concave lens thing is obviously something left over from our ancestors."

After she finished speaking, she bowed politely to the history teacher and said politely:

"Teacher, I'm done. The above are all my doubts."

After Daiyu finished speaking, the class fell into dead silence.

Many classmates also took out their mobile phones and started searching on Baidu.

No one in the class had ever openly challenged Liao Qiuxia's authority, not to mention that this was theoretical knowledge set in stone in the textbook. She began to get hysterical:

"So, Mr. Lin, what do you mean? You don't admit that foreign technology is more advanced than ours, right?"

Daiyu just replied calmly:

"That's what I meant literally. I think the Chinese have their own history and pride, and there's no need to belittle themselves."

In recent years, China's economy, technology, education, etc. have all developed by leaps and bounds, but there are still many Chinese people who believe that the moon in foreign countries is rounder than that in China.

Regarding this point, Daiyu has been browsing Baidu on her mobile phone these days and often sees those comments.

She just discussed this issue with her classmates and teachers from a more objective perspective.

There has been a huge change in the history teacher's attitude.

To be honest, when Daiyu couldn't answer the simple question on the blackboard just now, he actually suspected that she was a fool, but after listening to Daiyu's analysis and explanation.

Then he realized that he was the idiot.

At least Daiyu was honest and admitted that she didn't know about the Renaissance.

Moreover, the questions she raised were very good. Comparing the time points of the two sides, it is true that China proposed the theoretical viewpoint earlier.

"Pa pa pa", the history teacher took the lead and gave Daiyu applause:

"Student Daiyu raised a very good question. After the primitive society used fire-making by drilling wood, the use of Yangsui to make fire was a major change in the way humans made fire, and it was a milestone in the development of social civilization.

Regarding the view in the textbook that 'Leonardo da Vinci was the first to propose the use of solar energy and had planned to use concave mirrors to boil water through solar energy', this view does have some loopholes and flaws.

Afterwards, I will contact the Municipal Bureau of Culture to make suggestions, hoping to explain it more accurately.”

The students in the audience followed suit and applauded.

It is commendable to keep thinking and questioning when everyone believes in the authority of textbooks.

The history teacher further strengthened La Daiyu's determination to conduct scientific research on ancient culture.

The willow tree banged on the phone with a series of "bang bang bang" sounds.
