Zhao Jun almost died of laughter after hearing this.

The people in Nini Village are simply a bunch of weirdos. They are said to be knowledgeable, but they don’t even know the use of mathematics.

It can be said that they are uneducated and illiterate, but they are also well-versed in history books and have some insights into history.

This is outrageous.

But he also knew that it was not surprising that such a thing happened.

Because the village chief Uncle Lari told him that the reason why most villagers can read and like to read history is because there was an old scholar in the village who taught the villagers to read.

After the old scholar died, he left behind a lot of history books, mostly about the history of the Song Dynasty. The villagers used these history books as a pastime to pass the time.

This reason can explain it.

No wonder everyone likes the history of the Song Dynasty. So this is what it is like.

Zhao Jun somewhat understood why the villagers acted both knowledgeable and illiterate.

But he didn't show any impatience because of this.

Because pretending to be cool in front of people who seem to understand but don't really is unfathomable.

Pure illiterates don't understand anything. No matter how clever your words are, they will just treat them as nonsense.

Only those who know a little but not much can be fooled by using things they don't understand to fool them.

Zhao Jun smiled and said, "Mathematics is the foundation of science. The development of physics, chemistry, and biology all rely on mathematical calculations. Without mathematics, science would be impossible to advance."

"Can you give me an example?"

Zhao Zhen said.

"Let's talk about chemistry. Chemistry is a rigorous experimental science that focuses on experiments, but experiments require calculations and data."

Zhao Jun said: "For example, chemical reaction rates, changes in material conversion energy, and changes in molecular structure all require mathematical methods such as calculus, linear algebra, and vector analysis to perform structural calculations. Therefore, mathematics is widely used in chemistry."

"Forehead......"

Zhao Zhen, Lu Yijian and others looked at each other. Compared with Zhao Jun, they felt like illiterate.

"Teacher Zhao, I still don't understand. Can you be more superficial?"

Wang Zeng asked.

hey-hey.

Zhao Jun felt proud.

If I were to be more superficial so that you could all understand me, how would I stand out from the crowd?

He is a liberal arts student in the history department. He is not very well-versed in science, and his limited science knowledge is only at the junior high and high school level.

But that doesn't stop him from showing off.

Because in his opinion, Nini Village needs an excellent volunteer teacher who can make the adults in the village believe that as long as they hand their children over to him, they can cultivate promising children and change their fate of poverty in the future.

So how can he convince the villagers that he is such an excellent teacher?

Naturally, it shows one's outstanding level of knowledge.

By then, won’t the village be in chaos?

He immediately said, "You all should know about fertilizers. Fertilizers can increase grain production, turning 500 kilograms per mu into 1,000 kilograms per mu. The synthesis of fertilizers requires mathematical calculations."

"I see."

Everyone pretends to understand, but in fact they still don’t understand.

But everyone heard one thing keenly.

The yield per mu increased from 500 kilograms to 1,000 kilograms?

Good job.

Is this fertilizer really so magical in its decomposition ability?

If the yield per mu could be doubled, wouldn’t the Song Dynasty be invincible?

For a moment, everyone looked at each other and understood.

This new course still needs to be taught.

Zhao Jun then talked about some applications of mathematics in physics and biology.

For example, physical experiment operations, physical formula calculations, physical science counting; biostatistics, informatics, ecology, etc., all cannot be separated from mathematics.

It can be said that mathematics seems to be of no use in real life. Most people only need to learn addition, subtraction, multiplication and division.

But if other sciences are involved, a huge amount of mathematical knowledge is required.

This is also the reason why almost all majors such as physics, chemistry, biology, etc. have a course called advanced mathematics, commonly known as advanced mathematics class.

And everyone listened with fascination.

Although I don’t understand it, I always feel that science is a very powerful subject.

It seems I need to listen and learn more in the future.

"Also, mathematics is a very practical subject. For example, if I were Emperor Jingzong of Liao after the Battle of Gaoliang River, and I knew mathematics, then I could calculate the speed of Zhao Guangyi's donkey cart as he fled."

Zhao Jun gestured with his hands. "Zhao Guangyi raced over 140 miles in one night, his donkey cart drifting, demonstrating superb driving skills. If we count one night as 12 hours, his speed would be 11.6 miles per hour. If the Liao Dynasty were to send its elite cavalry in pursuit at a speed of 23 miles per hour, they would corner him in Dingzhou in two days, behead him beneath his donkey cart, and save the Song Dynasty from imminent danger."
