"You mean, is this world round?"

Tonglan looked at him in surprise, but she didn't expect the old man to react so quickly.

You should know that the world is round, which is refuted by most people's cognition.

"How is it possible? How is the world round?" Many people subconsciously retorted, even if the person in front of them was their dean, the world was round and so was so sensational.

"Yes, the world is a ball!" Tonglan shrugged and looked at the other students contemptuously: "He is much smarter than you."

One sentence choked everyone to death.

I wanted to curse, but that person was the dean of the academy.

But no matter what, I cannot agree with the conclusion that the world is a perfect one.

Not to mention a ball.

"If it's a ball, why didn't we fall down when we stand on it?" Someone immediately questioned.

"This ball has gravity. As I said just now, as one of the basic forces in this world, gravity is everywhere. However, the larger the mass, the greater the gravity."

"One of the basic forces of the world? What does it mean?"

"Graining force, electromagnetic force, weak interaction force, strong interaction force. Of course, you can't understand even if I say it." Tong Lan said with a light snorted.

She hates doing useless things.

She doesn't like these Izumo people either.

But she also doesn't like being questioned.

Everyone thought it would be lightning, time, etc., but Tonglan couldn't understand the few words he said.

Even gravity was only understood by Tonglan just explained it.

"Dean, how could you say that the world is round?" Ma Hualong asked Ning Changqing respectfully.

He really respects Ning Changqing.

He was rejected by Wangjing Academy back then, and he felt sad and angry. If he had not been accepted by Ning Changqing to Xiaojiang Academy, he would not know what he would have.

He only knew that the dean had great kindness to him.

"Someone has had such a guess... or many people have such a guess." Ning Changqing stroked his beard and said.

He has always ignored this speculation and listened to it as a joke.

Just now, when Tonglan heard the masts and the moon on the ship's outbound sea, he immediately thought of it.

"There are still smart people, but unfortunately it's not you." Tonglan really had no good expression on everyone, as cold as ice, and always had thorns in her words, which made everyone very angry.

"The masts disappeared in the end, and the masts appeared first when the ship returned, which proves one thing that seemed flat, but actually had curves.

The same is true for the red and yellow moons.

When the dusk moon appears, the red moon blocks part of the yellow moon, and how does the yellow moon look different from what you usually see?

Not.

This is because after the sun sets, it is on the back of this world that blocks part of the sunlight, so a crescent moon appears!”

"Impossible, the dark moon was blocked by the red moon because the light of the yellow moon was shining!" Someone immediately argued.

Tonglan seemed to be amused by these words, the ice and snow passed away, and her smile was revealed.

"The yellow moon shines brightly? You may not even know what the moon is, right?"

"And how do you explain the curve of the sea?"

Although it was difficult for everyone to answer, someone immediately shouted: "After all, you are just guessing and have no real evidence to follow it. In any case, I don't believe that this world is round."

Tonglan's eyebrows frowned slightly, these stubborn guys.

"You Xiaojiang Academy students are just messing around like this?"

"It's because you said that the evidence is not enough. The arc of the sea alone cannot explain everything." Cao Gui couldn't help but take a step and speak.

In any case, he could not accept that the other party belittled the academy so much.

But after saying that, he turned his head and looked at everyone: "I heard Miss Tong finish her words. After reading for so many years, where have you read?"

Tonglan rubbed her eyebrows: "Just as I said before, you don't know what the moon is. Do you think the moon can shine? In fact, the moon is just a huge stone ball.

Can a stone shine?

In the darkness, put a stone on the ground, can you see it?

Only when there is light can you see it.

For the specific reason, this involves the principle of light...

But there is one thing you just need to think about is that if the moon cannot shine, then on the back of the sun, part of the light is blocked by the world, and the other part of the light shines on the red and yellow moons, so you will see the crescent moon.

It is precisely because the world is round that we see the crescent moon.”

"Even if that's the case, maybe the world is like a plate and cannot be considered round."

"So there are also curves on the sea surface and curves on the surface. Adding these two points can prove something."

Tonglan explained with a crazy look on his face, and Shi Yu and the people from Zhitai Academy also arrived here.

"What are you discussing?" Shi Yu asked curiously.

"Tell them again that this world is a ball!" Tonglan looked depressed.

I had known that I wouldn't say much, but so many things were involved.

"Is the world round?" This statement aroused the exclamation of many women in Zhitai Academy.

Shi Yu felt a little funny when he saw Tonglan in a dilemma. He ignored the people of Zhitai Academy and said to Tonglan: "Isn't it enough to let them go to heaven and see the curves of the earth with their own eyes?"

"In heaven?"

"Can you see the curve of the earth?"

The students from the two academies were immediately attracted by this sentence.

"What do you mean is to be able to go up to heaven? How to go up? What is the heaven like?"

"I'll ask you. If you borrow Mr. Li's hot air balloon, you can take you to heaven." Shi Yu smiled at everyone.

"That's his life!" Tonglan snorted lightly.

"He is not that stingy, and don't forget the plane we are studying, the hot air balloon has been eliminated." Shi Yu said patting Tonglan's arm.

Everyone in Xiaojiang Academy next to him was still telling the people of Zhitai Academy that Tonglan said that "the world is a ball."

After all, the many women in Zhitai Academy are full of intellectual aura, which makes many students in other academies feel a little eager.

Shi Yu turned his head and looked at him, stood beside Tonglan and said, "It is said that there will be a lecture for a few days in the next few days, and people in each academies will come up to talk about things. The ghost didn't say anything to us, but we can tell that the world is round."

"At that time, those people will explode again." Tonglan snorted lightly. She felt troublesome to these dozens, let alone hundreds of people.

"Do you think they will tell the students from other academys when they go back?" Shi Yu smiled. Although he does not have the exquisite beauty of Tonglan, he is also the best at work.

There are no ugly girls in the ancient clan.

After everyone said that, they finally calmed down, Tonglan said expressionlessly: "Let's go back and ask if you can let you go to heaven and see it. It's useless to talk about this topic now. Today's tour is not over yet, let's go."

Next, in addition to a few academies, there are laboratories and workshops.

These laboratories are different from the teaching sites of the previous chemistry laboratories that let students understand chemical reactions. The subsequent laboratories are all places where new technologies are being developed.

Although the highest-end technology is in the laboratory in Zhongshishan, with hundreds of scholars and dozens of sword masters tied back from the earth, the research of these laboratories in the academic institution is also not simple.

For example, an airplane.

Zhongshishan has the progress of the aircraft, including the technical reserves of engines and other aspects, and the overall design of the aircraft, which is now roughly at the level of World War II.

However, students in the institution are also studying their own aircraft.

Of course, the engine drawings are provided by Zhongshishan Laboratory.
