Do you mean that the world is round? "
Tong Lan looked at him in surprise. She didn't expect him to react so quickly.
The world was round, which contradicted most people's understanding.
"How is that possible? How can the world be round? " Many people subconsciously refuted. Even though the person in front of them was their dean, saying that the world was round was too sensational.
"That's right, the world is a ball!" Tong Lan shrugged her shoulders. Then, she looked at the other students contemptuously and said, "He is much smarter than all of you."
His words made everyone choke to death.
They wanted to scold him, but he was the dean of the academy.
However, they couldn't agree with the conclusion that the world was round.
Not to mention that it was a ball.
"If it's a ball, why didn't we fall when we were standing on it?" someone questioned immediately.
"This ball has gravity. As mentioned just now, gravity is everywhere as one of the fundamental forces of this world. However, the greater the mass of an object, the greater the gravity. "
"One of the fundamental forces of the world? What do you mean? "
"Gravity, electromagnetic force, weak interaction force, strong interaction force. Of course, you won't understand even if I explain." Tong Lan snorted softly.
She hated doing useless things.
She didn't like the people of the Yun Nation either.
However, she also didn't like being questioned.
Everyone thought that it would be thunder and lightning or time, but they couldn't understand the words that Tong Lan said at all.
They only knew about gravity after Tong Lan explained it to them just now.
"Dean, why did you say that the world is round?" Ma Hualong asked Ning Changqing respectfully.
He really respected Ning Changqing.
He was rejected by the Wangjing Academy back then and was filled with grief and indignation. If Ning Changqing hadn't accepted him into the Xiaojiang Academy, he didn't know what would have happened to him.
He only knew that he was indebted to the dean.
Ning Changqing stroked his beard and said, "Someone had such a guess … or rather, many people had such a guess."
He had always been noncommittal about this guess and treated it as a joke.
When he heard Tong Lan mention the mast and the dim moon, he immediately thought of it.
"There are still smart people, but unfortunately, they aren't you." Tong Lan really didn't have a good expression on her face. She was as cold as ice and her words were always sarcastic, which made everyone extremely angry.
"When a ship goes out to sea, the last thing to disappear is the mast. When a ship returns, the first thing to appear is the mast. This proves one thing. The surface of the sea looks flat, but it is actually curved.
It was the same for the red and yellow moons.
When the dim moon appeared, the red moon blocked a part of the yellow moon. But what was the difference between the yellow moon and the one he usually saw?
Not at all.
This is because after the sun sets, it will be on the other side of this world. The world will block a portion of the sunlight, so there will be a crescent moon! "
"That's impossible. The dim moon is because the yellow moon's radiance was blocked by the red moon!" Someone immediately refuted.
Tong Lan seemed to be amused by these words. The ice and snow melted away, leaving a wide smile on her face.
"Yellow Moon Radiance? You probably don't even know what the moon is, do you? "
"And how do you explain the curve of the sea?"
Although the crowd found it hard to answer, someone immediately shouted, "In the end, it's all just a guess. You don't have any concrete evidence, so you just treat it as a theory. No matter what, I don't believe that the world is round. "
Tong Lan frowned slightly. This bunch of stubborn fellows.
"How can the students of the Xiaojiang Academy be so unreasonable?"
"You don't have enough evidence. Just the curve of the sea can't explain everything." Cao Gui couldn't help but take a step forward.
No matter what, he couldn't accept the other party belittling the academy.
However, after he finished speaking, he turned to look at the crowd and said, "Let Miss Tong finish speaking. Where have all the years of studying gone?"
Tong Lan rubbed her brows and said, "Like I said before, you don't know what the moon is. Do you think the moon can emit light? In fact, the moon is just a huge stone ball.
Can a stone emit light?
In the dark, if a stone is placed on the ground, can you see it?
You can only see it when there is light.
As for the specific reason, it involves the principle of light …
However, if you think about it, you will understand. If the moon can't emit light, then the sun is on the other side of the world. Part of the light is blocked by the world, while the other part shines on the red and yellow moons. That's why you see the crescent moon.
It's precisely because the world is round that you can see the crescent moon. "
"Even so, maybe the world is like a plate and can't be considered round."
"Therefore, there is also the curve of the sea and the curve of the earth's surface. Adding these two points can prove some things. "
Tong Lan explained frantically. Meanwhile, Shi Yu and the rest of the people from the Zhitai Academy had also arrived.
"What are you guys discussing?" Shi Yu asked curiously.
"Telling them that the world is a ball!" Tong Lan looked depressed.
If she had known earlier, she wouldn't have said so much. In the end, so many things were involved.
"The world is round?" These words caused many girls from the Zhitai Academy to exclaim in surprise.
Shi Yu saw Tong Lan's embarrassed look and found it a little funny. Ignoring the people from the Zhitai Academy, he said to Tong Lan, "Can't you just let them see the curve of the earth with their own eyes?"
"In the sky?"
"They can see the curve of the earth?"
The two academy students were immediately attracted by this sentence.
"You mean they can go to the sky? How do they go up? What does the sky look like? "
"Let me help you ask. Borrow Old Li's hot air balloon, and he can take you to the sky." Shi Yu smiled at everyone.
"That's his lifeblood!" Tong Lan snorted.
"He's not that stingy. Also, don't forget that we are researching airplanes. That kind of hot air balloon has already been eliminated." Shi Yu patted Tong Lan's arm and said.
At the side, the people from the Xiaojiang Academy were still telling the people from the Zhitai Academy about the 'world is a ball' matter.
After all, there were many girls from the Zhitai Academy, and they all had an intellectual aura about them. This inevitably made the students from the other academies a little enthusiastic.
Shi Yu turned his head to take a look, stood beside Tong Lan, and said, "I heard that there will be a lecture in the next few days. All the academies will send people to give lectures. Yagui didn't say anything to us, but we can talk about the world being round. "
"I'm afraid those people will explode again." Tong Lan snorted. She already found it troublesome to deal with a few dozen people, let alone a few hundred.
"Do you think they won't tell the students from the other academies when they return?" Shi Yu laughed. Although he wasn't as exquisite as Tong Lan, he was still superior.
There were no ugly girls in the aboriginals.
When the people on the other side were almost done and finally quietened down, Tong Lan said expressionlessly, "Go back and ask if you can take a look at the sky. There's no point talking about this topic now. Today's tour isn't over yet. Let's go. "
Other than the academies, there were various laboratories and workshops.
These laboratories were different from the chemistry laboratories that were used to teach students about chemical reactions. The laboratories at the back were all places where new technology was being developed.
Although the most advanced technology was in the laboratory on Mount Termination, where there were hundreds of scholars and dozens of sword masters that Ren Baqian had kidnapped from Earth, the things that the laboratories in the academy were researching weren't simple either.
For example, airplanes.
The progress of airplanes in Mount Termination, including the engine and other technical reserves, as well as the overall design of airplanes, had roughly reached the level of World War II.
However, the students in the academy were also researching their own airplanes.
Of course, the engine blueprints were provided by the laboratory on Mount Termination.
Even so, the things that these students accomplished were enough to put most people to shame.
