"Zhou Juma, you say." Someone shouted.

Zhou Jinyan glanced at the man, "According to what you said, if the earth is flat, theoretically, without any obstruction, can you see infinity?" ”

As soon as the question came out, everyone fell into deep thought.

It took a long time before he was humanized: "You don't need to think about this, it's true." ”

"Good."

Zhou Jinyan looked at the person who answered, and found that it was Kong Yingda, so he couldn't help nodding to him.

"Do you agree?" Zhou Jinyan looked at the others again.

Soon someone nodded, and everyone still believed this.

"Not necessarily, right?"

Suddenly, Wang Lan said: "I used to be in a spacious place, but I couldn't see infinitely far. ”

Zhou Jinyan glanced at her, "Please note that what I said is that if the ground is flat, if you see the ground is uneven, your vision will naturally be obstructed." ”

Wang Lan snorted and twisted her head to the side.

"It's much easier to determine this problem," Zhou Jinyan said with a smile: "Everyone, look at Qujiangchi." ”

Everyone looked at the place he pointed, and the Qujiang Pond was very wide, and they couldn't see the edge at a glance.

Everyone looked at him suspiciously, not knowing what he meant.

"Ahh

Zhou Jinyan shouted loudly.

As soon as the words fell, a small boat propped up the pole and went away, and the speed was extremely fast.

The boat was supported by a wooden stick that was always red, and the stick was very long.

Seeing that everyone was puzzled, Zhou Jinyan smiled and said: "It's hard to say whether it is flat or uneven in other places, but the water surface of this Qujiang Pond must be equal to the same height, you don't have an opinion on this, right?" ”

Li Baiyao thought thoughtfully, "No problem, you continue." ”

Zhou Jinyan pointed to the boat that Ah Da was getting farther and farther away, "The boat seems to be getting farther and farther away from us, isn't it?" ”

Li Baiyao suddenly said: "What do you mean, if it is horizontal, this small boat will not disappear in our eyes?" ”

Zhou Jinyan nodded approvingly, and continued: "It may be a little difficult to understand this, let's make it simple." ”

He looked at the boat that was getting farther and farther away, and said, "You should still be able to see this boat clearly, you can see it clearly." What part of the boat do we lose sight of first, and what part of the boat do we see last? ”

At this time, the eyesight is not as good as that of later generations, and there are not a few people who have built the foundation, and their eyesight is far stronger than that of ordinary people.

"The hull is gone." Suddenly, someone shouted.

"I can still see the red stick."

"The stick is gone."

......

Zhou Jinyan smiled and listened to everyone's discussions, and said with a smile: "Do you still understand what I mean?" ”

"What do you mean?"

Wang Liancheng didn't react for a long time.

"It's very simple," Zhou said, "if the ground was flat, we should have seen the boat all the time, but unfortunately, the boat eventually disappeared." ”

Zhou Jinyan snapped his fingers, and soon Yueji walked up with a globe in her hand.

Zhou Jinyan took the globe.

"Look, if we live on a sphere of this shape, it's easy to explain why the boat disappeared just now, why the hull disappeared first, and then the red sticks."

He reached out from Tsukihime and took another paper boat, and placed it on the globe to simulate it.

"You see, our eyes are at this point, and if it stretches into a straight line, this little boat is slowly descending from the sphere, and the first thing we can't see is the hull, does it make sense?"

"But because the sticks are tall, we can still see them, which means they're the last to disappear."

"It can be seen that we live on a sphere, not a so-called round place."

"If the earth were square, the situation just now would not have happened."

The audience was silent, but most of them seemed to understand.

Those who can see clearly are martial artists, and those who can't see clearly are learned people.

Zhou Jinyan sighed and said casually: "Is there anything else you don't understand?" ”

Everyone present whispered.

Kong Yingda said: "There is indeed some truth in what I said, but this does not seem to prove that we live on the sphere." ”

"Isn't it a joke to say that we should live on the sphere again?"

Wang Lan pointed to the sphere in Zhou Jinyan's hand, "Look, if we are at the bottom, won't we fall down?" ”

Li Baiyao said with a smile: "Don't forget, as long as he proves that it is not a round sky, he will already win." ”

Wang Liancheng was unconvinced: "So far away, who must be sure that the hull of the ship is missing first, and only the wooden stick can be seen in the end?" I can't see it anyway. ”

"Those who practice martial arts should be able to see it."

Li Baiyao and Kong Yingda glanced at each other, and they were actually puzzled in their hearts, after all, they hadn't seen it. It's all said by those warriors.

"Husband, this is going to win?"

Li Mengjiang looked at Zhou Jinyan on the stage blankly, a little incredulous for a while.

"It's like you're going to win. But I'm confused, I don't understand it. Gao Yang scratched his head, a little puzzled.

"I don't understand either. It's so esoteric. Du Yanran was also at a loss.

"But the discussion seems to be in favor of the husband." Li Mengjiang came with a little confidence, "Everyone thought that the husband was crazy before." ”

As soon as the words fell, someone said: "Zhou Yuma, your statement can't convince me to wait, so far, the ghost knows if the hull came out first, or the wooden stick fell later." ”

"It's, maybe it's because of the perspective? It's not enough to be believed, anyway. ”

Zhou Jinyan said expressionlessly: "Who of you doesn't believe it? I can make him see it clearly. ”

Everyone was stunned, but soon someone said, "I'm coming." “

Zhou Jinyan looked at the lofty and big life in the future, and he was rich and noble, but there was arrogance on his face, which made people feel slightly unhappy.

"Hoshihime."

Zhou Jinyan no longer looked at him, but shouted backwards.

Soon, Xingji slowly walked over with a tray.

The man looked at Yueji, then at Xingji, and couldn't help but say: "Zhou Yuma is really romantic, beautiful. Blessing is enviable. ”

"Hehe, thanks for the compliment."

Zhou Jinyan said, took something from the tray, lit it with fire, only to hear a stabbing sound, and a flame rushed up to the sky.

The man was so frightened that he took two steps back, and said with a pale face: "You, what are you doing here?" ”

"Nothing,"

Zhou Jinyan took another thing from the tray and handed it to him: "This is called a telescope, if you look at the distance, can you see it clearly." ”

The man glanced at him suspiciously, put the telescope in front of him in the way of Zhou Jinyan, and quickly exclaimed, "I'll go, what is this?" How can you see so closely, so clearly? ”

As he spoke, he turned to look around.

Zhou Jinyan grabbed him, "This brother, you look at the front first, and then see if you see the wooden stick first, and then see the hull." The latest chapter of "Hundred Plating" mixed in the Tang Dynasty to be a horse claw book house" is free to read for the first time.
