Next.

Prince Xiang Tiange, Yang Sui, Shen Xiaomei, Xiao Xiao and other teenagers and girls came to the Wanghou Academy one by one with dark circles under their eyes.

looked at each other, miserable, and wanted to cry without tears.

That's it, what else is there to talk about feelings.

As soon as they went home, they cried that the study of the Princely College was too difficult, and it was too hard to study for four or five hours a day.

They don't want to go to the Royal Academy, they want to change to a more relaxed college, and I heard that Jinling Academy is very good.

The scholars and Confucian students are all elegant and graceful, and they talk loudly in the academy every day, sit and talk about the Tao, and their words are "the ones who are concerned", and the great truth of life.

But they were still forced by the family with big sticks and escorted by the guards.

Because the princes, gate lords, and eunuchs of Jinling heard the news from a group of new science and technology scholars, the new mathematics that Xiao Duhou had drummed up was too strong, and it was all breakthrough.

It's like hemp paper, promoted to faint paper, and the two can't be compared at all.

Once the teenagers have completed their studies, they can be a full generation ahead of their peers, and each of them can be compared to Dongfang Su and Sang Hongyang, the two Gengzi imperial examination scholars, so that other students can't catch up.

There are many extremely rich and powerful families in Jinling City, and they can't squeeze into this princely academy.

How could they, the princes and the sons of the gate lords, miss such an opportunity.

Besides, there are still twenty jinshi who accompany the teenagers to study, what can't they learn.

...

Chu Tianxiu was catching up with the schedule.

In the second class, he began to teach physics and chemistry in elementary school.

Gravity and gravity, buoyancy, light and eclipses, lunar eclipses, light and concave lenses, heat and temperature, pulleys and gears....

"A bunch of scum!"

"The combat power is too weak!"

Chu Tianxiu was furious.

This is obviously a popular science level course for elementary school students, and a group of you are thirteen or fourteen years old, or even almost seventeen or eighteen years old, is it so difficult to learn?!

A group of teenagers and girls went to class, and they all opened a pair of confused eyes, listening in the clouds, and they didn't know why.

I'm about to be.

But fortunately, his real target is not this group of princely boys.

Let the princely boys know that there is such a thing, and it is enough to have these things.

The crown prince Xiang Tiange, as well as the descendants of the princes and gate lords, will take over the many powers of Dachu in the future. It is naturally beneficial to let this group of people have a little more knowledge.

These twenty jinshi are his teacher seeds.

First of all, the church will teach these 20 jinshi who can read the best. Then let them each bring a group of apprentices to spread out in the Great Chu Dynasty and improve the knowledge level of the entire Great Chu Dynasty.

With this popular science knowledge, an industrial revolution can be started!

He didn't want to let himself stay on the podium for a decade or two, and he wouldn't be pissed off by these stupid pigs.

...

"Gravity and gravity!"

"Everything is subject to gravity."

"The one that falls to the ground is called 'gravity.'"

"Stars are attracted to each other by gravity. This is true of the Earth, the Moon, and the Sun. The heavier the mass, the greater the gravitational pull, and both the earth and the moon revolve around the sun. ”

"As for the earth, they are all attracted to the earth and can only fall on the ground."

Chu Tianxiu was on the podium and said lightly.

Anyway, he only said it once, and the rest is up to fate.

I really can't learn it, so go back and read the textbook.

Dongfang Su, Sang Hongyang, and all the Jinshi were dumbfounded, trembling with excitement.

Finally, the true meaning of the national examination questions appeared.

The third question of the Xiaoduhou National Examination, "Wood, copper, iron, one pound each, the three things fall together, who will land first?" ”

Intuitively, though, iron should be the first to fall.

However, considering that the three objects weigh the same, they should fall to the ground together.

But who landed first and how to calculate it is a big problem.

"Enza, "Shangshu, Yushu, Yaodian" said. The sky is round like a cover, and the ground is like a square chess game. Therefore, it is said that the sky is round and the place is round!

It seems to be in conflict with your explanation of the 'earth'? Where we stand, is it a ball? Or a flat lying on the ground?! ”

Dongfang Su asked.

"Not bad!"

The Jinshi also nodded one after another.

In the records of countless classic books of Dachu, there is only a description of "the sky is round and the place is round", and there is no description of "ball".

The earth should be flat, otherwise how can people stand on it?!

If it's a ball, people will fall to both sides!

"The earth is extremely vast, tens of thousands of miles away, so the arc of the earth is not obvious. People are like ants, only half a foot long, and they can't feel the existence of arc under normal circumstances.

Hundreds of miles away, the appearance of arcs can be seen.

It is best to observe on the flattest sea. When the sailing ship goes out to sea, the mast gradually sinks from the surface of the sea, which is the greatest evidence of the existence of the arc of the earth. ”

Chu Tianxiu said casually.

The Jinshi looked at each other, many of whom had never seen the sea in their lives.

"What Enzuo said is that I am a salt merchant in Qi State, I live by the sea, and I often went to the beach to dry salt when I was a child.

When a ship goes to sea, the hull disappears first, and the mast falls last. Every time the ship returns, it is a first sight of the mast, and then a hull.

The disciple has been drying salt on the beach for more than ten years, and he never thought that there is a great truth of the earth in this.

With this statement, the disciple suddenly realized that this must be the circle of the earth. The view was obscured by the ground.

Grace, but once watched the sailing ship go to sea on the beach, and realized the road?! ”

Dongguo Xiangyang admired the five-body throwing to the ground, Dao.

"Nope."

Chu Tianxiu shook his head.

All of this knowledge was learned in his primary and junior high school textbooks in his previous life, and it was a common sense of popular science.

Since crossing over to Dachu, he, the little marquis, has not even been far away from Jinling City in his life, and the farthest is Danyang County, which is a hundred miles away.

The Jinshi couldn't help but be shocked.

Could it be that Teacher, this is a saint who is born to know?

It's too tough.

The sages and Confucians such as Confucius and Mencius during the Spring and Autumn Period and the Warring States Period were nothing more than that.

Many physical chemistry courses require hands-on operation and observation, which is much more interesting than pure mathematics.

Gravity, buoyancy, light, can all be seen with the eyes.

However, Chu Tianxiu soon found that there was no concave-convex mirror.

The royal family and nobles of the Great Chu Dynasty all used polished and smooth bronze mirrors as mirrors.

Without transparent and translucent glass, there is no concave-convex mirror to refract light, and young students can't imagine what the concave-convex mirror is for.

Forget it, skip!

When he has time to make glass, he can make concave-convex mirrors.

Glass is a good thing, glass, mirrors, can make a lot of money. Sell it to those nobles of Great Chu, buy it to the countries of the Western Regions, buy it to the Xiongnu noblewomen, and blind their dogs.

Also, magnifying glasses, microscopes, which are the key to seeing bacteria, and medical schools need this thing.

A telescope with seven to ten times magnification, a sharp weapon for fighting wars and military observation. With this thing, the sentry can easily see the enemy's formation, as well as their own intelligence.

Chu Tianxiu smiled.

This requires a large number of talents to study glass.

He had to popularize the popular science knowledge at the junior high and high school levels as soon as possible, and then start a batch of industrial projects.

When the time came, he recruited a group of investors, as well as a group of top-level technical talents, and began to stake his land in the Great Chu Dynasty.
