Li Chenghua looked at Tang Bohu with anticipation?

He smiled and said, "Hehe, most people are confused about your question. In fact, it is very simple!

How to say it?

Walking with a heavy burden means that the weight of the human body suddenly increases a lot!

In this way, the trend of a person leaning forward and falling when walking is very obvious!

At this time, narrowing the steps can appropriately reduce this overturn trend.

At the same time, people need to move forward quickly by small steps to maintain the [center of gravity] to prevent falling!

Therefore, people who carry heavy burdens always walk small and fast, and their walking speed is faster than usual!"

Tang Bohu said: "Ah, [center of gravity]? So that's it! That is to say, this is a kind of self-adjustment of the human body? It's mainly because of the fear of falling?"

Li Chenghua nodded and smiled, "Yes! It can basically be understood this way. If you want to explain it in detail, it will involve a lot of scientific knowledge."

At this time, the thin talented man said unconvincedly: "It sounds so good."

But, Brother Li, why does it rain? Could it be that you know too?"

In the Tang Dynasty, it was actually all feudal dynasties, and they believed that it would rain because there was a dragon king in the sky!

Therefore, during drought, the court and the people all ask for rain from the sky.

Who dares to object to pray for rain? The consequences are very serious!

Wang Yunxian's father opposed seeking rain and advocated the construction of water conservancy facilities.

That's why he was dismissed from office! If it weren't for Lee Seung-hua's actions?

Wang Yunxian's father will definitely be ruined in this life!

Seeing this, we started arguing again?

Many students from the Imperial College ran over and watched.

At this moment, Li Chenghua glanced at the talented men watching?

Then, he smiled and said, "Why does it rain?"

First of all, I'm sure that there is no dragon king in the sky!

So, why does it rain?

That's because the water on the ground, rivers, lakes and seas, will produce a kind of air when exposed to sunlight!

We can call this gas - water vapor!

After this water vapor rises?

It will turn into small drops of water!

Finally, it turns into a cloud!

When there are more and more small water droplets in the cloud, they will fall off the cloud!

So—it’s raining!”

“…”

Where did students of the Tang Dynasty hear this theory?

Therefore, when I heard Lee Seung-hua say this?

The students of the Imperial College who were watching were all stunned!

All right!

This feeling is really standard [Unclear and sharp]!

Although they don't understand?

But they think Lee Seung-hwa is saying it very well!

At this time, the thin talented man snorted: "What? Water vapor? Clouds?

Isn’t this nonsense? It’s raining, it’s obviously relying on the Dragon King!”

Lee Seung-hwa snorted coldly: “I have said everything, there is no Dragon King!

As for what water vapor is? Actually, everyone knows it!

The gas that comes out when steaming rice is water vapor!

It was steaming when taking a shower, and it was also steam!

As for what is cloud?

The clouds floating in the sky are clouds!

Could it be that you can’t see the white clouds in the sky?

Of course, what if a lot of small water droplets formed by water vapor are gathered in the white clouds?

The color of the white cloud is no longer white or transparent! It becomes gloomy and will block the sunshine!

So, this is a cloudy day!

After tomorrow, it may rain!

Think about it, is this the case?

These are all science! As long as you are good at observing, you will always discover this rule!”

"Ah? Cloudy? Cloudy? Rainy? So that's the relationship..."

The students present were all a little confused at this moment.

There is no such content in the knowledge they learned before!

In their consciousness? It rains, it’s the Dragon King’s business!

If it rains is not the Dragon King’s business?

So how can I ask the Dragon King for rain in the future?

This is no trivial matter.

This is a kind of subversion!

At this moment, Tang Bohu was stunned for a while, then nodded excitedly and said, "Oh, what Brother Li said is extremely true! What he said makes sense! But, I still don't understand..."

Lee Chenghua smiled, took out a handkerchief, and went to the rockery next to him to get wet.

Then, Lee Seung-hwa said, "Did you see it? This handkerchief is the cloud! At this moment, if the clouds absorb enough water? It will rain!"

“…”

Looking at the handkerchief that ticked and dripped constantly?

Everyone present nodded foolishly.

At the same time, they seemed to have an enlightenment in their minds?

It seems that there is a layer of something, and as long as it is opened, they will enter a new world!

At this moment, the thin talented man was still dissatisfied and said, "You... can't explain anything!

OK, let’s not talk about the rain!

Then I ask you—why is it drought?”

Li Chenghua sighed and said, "You want to say that the drought is because the Dragon King is unhappy, isn't it raining?"

Actually, this is not the case!

Why is there a drought?

This is caused by many factors!

One is that the water vapor on the ground does not rise much!

The other is strong wind, heavy sand, etc., which causes insufficient water accumulation in the clouds!

So, it won't rain anymore!

Anyway, just like my handkerchief!

If the handkerchief does not absorb water, it will naturally not produce water inside the handkerchief!

The reason for drought is ultimately that there is no suitable water vapor in the clouds! Therefore, it will naturally not rain in the clouds!"

Tang Bohu slapped his head and said excitedly: "Yes! What Brother Li said makes sense!

Then... Brother Li, why do we see lightning first and then hear the sound when thundering?"

Li Chenghua patted Tang Bohu and said, "Can you ask this question? It proves that you really like to study and study details!

Why is this happening?

Haha, of course it’s not the eyes in front and the ears behind!
