Three Kingdoms: Faint King, starting from forcing Dong Zhuo to offer his granddaughter

"You are worried about falling because of this gravitational force. When our body stands upright on the ground, this gravitational force is in a straight line with our body."

Liu Bian found a ball, put some sticks on it as villains, and gave everyone a serious explanation.

Most people already understand it, while others are completely fooled.

Because they are still young, their understanding of the world is still blank, and they have not formed a fixed four-dimensional.Therefore, what Liu Bian said does not need to overthrow their original cognition, so it is easy to accept.

Before Cai Yong and others could react, the children had already understood.

The sky is round, and the earth is also round!

very funny!

"Speaking of the gravitational force of the earth, let me ask another question."

Seeing that they listened so earnestly, Liu Bian became more and more interested in lecturing, so why not tell them more interesting things to arouse their curiosity about the world and stimulate their desire to explore the world!

Maybe doing so can make China's Neo-Confucian knowledge ahead of the West by more than 1000 years.

After listening to the question again, everyone straightened up and listened carefully.

They felt that His Majesty's lectures were too interesting.

Compared with Mr. Shui Jing's boring ones, it's much more interesting.

"A one-jin iron ball and one half-jin iron ball fall from high altitude at the same time, which iron ball do you think will hit the ground first?"

Liu Bian looked at Cai Yong and the others with a smile, "You can also participate in thinking."

This is also called a problem?

"Your Majesty, this question is too simple. Of course, the one-jin iron ball hits the ground first."

Dian Wei did not hesitate, and was very sure.

"Do you think so too?"

Liu Bian looked at the others.

Many children nodded, and Sun Quan tilted his head with a serious face, "The big general is right, the heavy iron ball must hit the ground first."

"Cai Qing, what do you think?" Liu Bian continued to ask.

Cai Yong felt that the answer was not that simple, but he felt that what Dian Wei said was correct.

After thinking for a while, he finally said, "I agree with General Dian."

"Your Majesty, could it be that the small iron ball hits the ground first?"

Sima Yi asked curiously.

Liu Bian smiled slightly,

"Which iron ball hits the ground first, we'll find out by testing it ourselves."

"Everyone follow me to the city wall, Cunxiao, you go find two iron balls of different sizes."

Liu Bian led a group of children out of the classroom and went outside.

Many people were also very curious and came to watch.

When they learned about the problem His Majesty wanted to explore, they were very certain: the heavy iron ball must hit the ground first.

Almost everyone has this answer.

Soon, Li Cunxiao came over with two iron balls, and Liu Bian asked him to stand on the city wall.

And Liu Bian took the child prodigies and stood under the city wall.

"Everyone pay attention to observe."

Liu Bian reminded, and then shouted to Li Cunxiao, "Remember, you must let go at the same time, and you can start."

Li Cunxiao stretched out his hand,

then,

Let go at the same time!

"Snapped!"

The two iron balls fell to the ground at the same time, and there was only one sound.

Everyone exclaimed in disbelief,

"It actually landed at the same time!"

"Why didn't the heavy iron ball hit the ground first, and didn't the heavier one fall faster?"

Not the heavy ones hit the ground first, nor the light ones hit the ground first,

Two iron balls landed at the same time!

This experiment directly overturned everyone's cognition.

"Your Majesty, why is this?"

Cai Yong was puzzled, and the children and the surrounding people also looked puzzled.

Because in their cognition, heavy things must fall fast.

"This involves relatively profound knowledge of mechanics. I will explain it to you now, but you may not be able to understand it. Leave an assignment for you to think about."

It is indeed too esoteric all at once, and it is of little help to them.

"Your Majesty, if falling speed has nothing to do with weight, then why does a leaf and a pebble fall at the same time, and the pebble falls before the leaf?"

Zhuge Liang picked up a leaf and a stone from the ground and let go at the same time.

The leaves fluttered in the air, while the stones fell straight down.

This, how to explain?

Liu Bian looked at him and smiled slightly, he is really a little guy who likes to infer other things from one instance.

"This question was raised by you, so it's up to you to find the answer."

"Similarly, there is another problem. When two iron balls of different sizes are pushed out with the same strength, which one will roll longer on the ground? What about the iron ball and the iron block? You can try it out, and wait for you If you have the result, you can let me know."

Today, people know that it has something to do with friction.

But people in this era have no concept of friction.

Liu Bian felt that it was better to let them find out by themselves than to tell them directly.

Although Liu Bian does not intend to train them to become physicists, it is a way of thinking, an attitude towards learning and solving problems.

It will be very helpful for developing the limits of their abilities!

Experiments can most arouse the interest of learning.

The iron ball landing experiment that Liu Bian took with the Prodigy Academy at the gate of the city not only aroused their interest, but also aroused the interest of the whole city.

Soon, it will be everywhere in the city, and many people will test it out by themselves.

The answer I got was naturally unexpected.

After Zhuge Liang and others returned to the classroom, they began to experiment with iron ball rolling and iron block sliding.

The thinking of this group of children is expanding infinitely.

When leaving the Prodigy Academy, Liu Bian left some gifts for them,

Including, table of addition formulas, multiplication formulas, a map of the world, a map of Han, and a globe.

Of course, the map and the globe were purchased from the Guoyun Mall, and the contents marked on them are all contemporary.

For example, the world map includes the current territory of the Han Empire, Yamatai (Woshima Kingdoms), Western Regions, Wusun, Da Yuezhi, Guishuang, Khorezm, Anxi (Parthia), Rome and many more.

Seeing that there are so many countries and races in the world besides big men,

Everyone finds it incredible,

The world is far bigger than they imagined!

And when Liu Bian left, he left them a sentence, which had a great influence on them.

Liu Bian said, "I hope that in the future, there will be only one word in the whole world: Han!"

After leaving the Male Prodigy Academy, Liu Bian went to the Goddess Academy again.

Cao Cao said that when he conquered Hanzhong, he brought back a girl.

It is Zhang Lu's daughter, named Zhang Qiying.

Only six years old, but looks very smart.

In addition to Zhang Qiying, there is also Sun Jian's daughter Sun Ren, whose small name is Shangxiang.Xin Pi's daughter, Xin Xianying; Bu Zhi's daughter, Bu Lianshi.

Because both Simpi and Bu Zhi came to the imperial court to become officials, they heard about the various benefits of Imperial College, so they were willing to send their daughters there.

However, not all girls are quiet.

As soon as Liu Bian entered the gate of the academy, he was greeted by a pink fist.

This year,

Liu Bian's stature has grown a lot, and he is standing on the steps of the threshold.

This punch hits the nail on the head!

Because Cai Yan and Lai Yinger are in charge of the Goddess Academy, Cai Yong, the dean, cannot come here casually.

Therefore, Liu Bian came with Yinger.

How did he expect that the little girls were so fierce that they didn't react at all.

If it weren't for the Yin-Yang Ascension Jue that he had practiced for a year, and the Vajra Indestructible Dragon Body had already reached the fourth floor.

The dragon pillar has been cultivated to be very hard!

If it were an ordinary man, he might become a eunuch on the spot.

What's more, the perpetrator didn't even know where he was hit, and immediately rushed to the side without even saying sorry.
