It is a terrible thing for a person to have a curiosity beyond the times.

If he was not born as the eldest son of the royal family, and was responsible for inheriting the country's destiny, and was strictly educated since childhood, he would probably become a fantasy - thinking too much all day long but doing nothing.

It’s not that he doesn’t want to do it, but that he can’t do what he wants to do with the current technical conditions!

No matter who lives in the world and cannot do anything you like, you will feel that living is boring and it is normal not to want to do things.

So when he met such a person who had a vision that surpassed the times, even if Bai Jingyuan knew the truth but didn’t know the reason, he was still very excited!

"If we live on the surface of a ball, why didn't we fall down?"

Gongzisu's mind is now full of this world as a ball. Once he accepts this setting, his thinking will inevitably float here.

Originally, he just didn't want to talk about political affairs with this nephew, so he raised this topic, but now he really wants to know.

Seeing him looking at him with anticipation, Bai Jingyuan was very impressed!

If it falls, where will it fall?

A planet is so big, can it fall out of the atmosphere?

After thinking for a long time, I vaguely remembered a little bit: "It seems to be because of gravity?"

People are attracted by gravity to get close to the ground, so they will naturally not fall out of the atmosphere.

But what exactly is this gravity called? Bai Jingyuan said he was confused.

"Graining? What gravity?"

Gongzi Su had never heard of this word.

When he asked, Bai Jingyuan's memory became vivid.

"It should be...gravity?

He remembered Newton under the apple tree.

So he picked up a melon and let go of his hand, the melon fell to the ground.

"Look, this is gravity."

Young Master Su didn't understand and didn't fall to the ground, would he still fly into the sky?

Seeing his expression as if he looked at a fool, Bai Jingyuan said seriously: "Why does it fall to the ground instead of flying into the sky? It's because of the existence of gravity!"

Young Master Su fell into deep thought, and this deep thought lasted for several hours.

At first, Bai Jingyuan thought he would come back to his senses after a while, and was still waiting there stupidly. As a result, most of the hour passed and he had read a travel notes of Zheng State. He was still thinking in a daze. Bai Jingyuan was shocked! Then he settled down with his servant.

It was not until the next day that Young Master Su came to him with an apology.

When the ceremony was delivered, the young master bent his waist very deeply.

"I have never talked to others so speculatively. I have lost my composure at some point. I hope the king will not blame him."

Seeing that he was very respectful in his rituals, Bai Jingyuan was very surprised. He was obviously always holding his uncle's airs yesterday...

But he just whispered his heart, and still smiled: "I heard someone say before, I love my teacher, but I love the truth even more. My uncle is just obsessed with learning, so what can I blame?"

It has been so long, and Young Master Su is still excited because he has verified that the so-called gravity really exists.

"But how to calculate the magnitude of this force?"

Unexpectedly, this uncle is not only curious, but also likes to be poor!

Yesterday I thought that gravity had already burned high incense and accumulated virtue in my previous life. If he could know this, he would not be regarded as a fool and dare not talk back!

Seeing him looking at him with anticipation, Bai Jingyuan suddenly felt bald, as if the roasted rabbit in his hand was no longer fragrant.

With a sudden inspiration, he said, "Uncle should know that the sea of ​​knowledge is endless, Bai is still young! How can you know everything?"

"Hey! You're right, I shouldn't always think about getting something for nothing."

Young Master Su sighed regretfully, sat in melancholy for a moment, and cheered up again, because there were so many unsolved mysteries in his mind!

Since this nephew is a very thoughtful person, why don’t he talk to him and see what he will say?

So, Bai Jingyuan was nervous for a moment, thinking that he was going to use some big move, so he heard him say mysteriously:

"Do you know why Qishui never runs out?"

The water flows abundantly and has never been drought to the point where it is cut off, so it will naturally not dry up. What a stupid question?!

Bai Jingyuan thought so in his heart. He knew that this uncle had a clear mind and was not easy to say it. He just shook his head and said that he didn't know.

So the young master Su said, "I suspect that there is an infinite lake at the end of Qishui!"

After talking about this issue with Weng Liang before, he thought about it and still felt that this was the most likely one.

Bai Jingyuan was stunned!

Could it be that he thought that Qishui was constantly running day and night because there was endless flowing water in the upstream?

How much water should you store to withstand the flow of rivers day and night?!

It's a pity that he can think of it!

It’s really scary to share secrets! You should keep this secret by yourself!

Fearing to blow his fragile self-esteem, Bai Jingyuan said nothing, and only asked someone to take a bronze mirror and a can of hot water, and then pressed the bronze mirror upside down on the steaming water tank.

Young Master Su looked at him curiously: "What are you doing?"

Bai Jingyuan said: "Uncle, many principles are placed in front of us. If we just think about it, it may not have any results for a long time. Maybe it will be more useful if we verify it."

Young Master Su also knew that he didn't like to do anything, but he still felt embarrassed to be told by his nephew.

Bai Jingyuan's original intention was not to embarrass him. He clicked and turned up and turned over the bronze mirror.

"Uncle, look, what is this?"

Young Master Su reached out and touched him, then leaned under his nose and smelled it, then hesitated and said, "Is it water?"

"Isn't it amazing? The water in the jar ran to the mirror."

Young Master Su touched the bronze mirror that was still cool in summer, thinking about something.

He remembered that in winter, soldiers in the military camp wiped their weapons, and every time they breathed warmly, they would condense into water droplets on the weapons.

Is this the same truth?

Before he could ask, Bai Jingyuan said, "Hot steam will condense into water when it encounters cold things. Look, if the water in the jar is the water in the river, wait for it to free up water steam under the sun, and the water steam rises to the sky, and when it encounters cool air, it will be rain when it falls."

This is the simplest atmospheric water cycle, but unfortunately the people here do not have enough view of the overall situation.

Gongzi Su continued to ponder, and Bai Jingyuan did not interrupt him. Many questions were only useful if he understood them.

After a long time, Gongzi Su came back to his senses and said in dismay: "It turns out that the water in the world is not endless. The reason why the rivers keep flowing is because the steaming water vapor turns into water and is back again!"

Bai Jingyuan nodded: "Yes!"

How happy it is for modern people to stand on the shoulders of giants!

He remembered his nephew.

The reason why he knew this was because his nephew was only four years old and could speak these things very well, and his parents used it to despise him.

This cheap uncle is actually very smart, he gave birth to the wrong era and the wrong family.

He was destined to be the king and could not pursue these truths with all his heart.

Actually, it's quite pitiful.

Seeing him with such eyes, the young master escaped in panic.
