"You mean, the world is round?"
Tonglan glanced at him in surprise, she didn't expect the old man's reaction to be so fast.
We must know that the world is round, which contradicts most people's cognition.
"How is it possible? Why is the world round?" Many people retorted subconsciously, even if it was their dean in front of them, the words that the world is round are too sensational.
"That's right, the world is a ball!" Tonglan shrugged. He glanced at the other students contemptuously: "He is much smarter than you."
One sentence choked everyone to death.
He wanted to open his mouth to curse, but that person was the dean of the academy.
But in any case, it is impossible to agree with the conclusion that the world is a circle.
Let alone a ball.
"If it's a ball, why didn't we fall down?" Someone immediately questioned.
"This ball has gravity. As I said just now, as one of the basic forces of this world, gravity is everywhere. 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 don't understand what I said." Tong Lan said with a soft snort.
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 thunder and lightning, time or something, but the few words Tong Lan uttered were completely incomprehensible.
Even the gravitational force is only known by Tonglan's explanation just now.
"Dean, why do you say the world is round?" Ma Hualong asked Ning Changqing respectfully.
He really respects Ning Changqing.
I was rejected by Wangjing Academy back then, and felt sad and indignant. If Ning Changqing hadn't been accepted into Xiaojiang Academy, he didn't know what would happen to him.
He only knew that the dean had a great favor for him.
"Someone has had such a guess... or many people have had such a guess." Ning Changqing stroked his beard.
Regarding this guess, he has always been noncommittal, listening to it as a joke.
Just now when Tong Lan mentioned the mast of the ship going out to sea and the faint moon, she immediately thought of it.
"There are still smart people, but it's a pity that it's not you." Tonglan really didn't have a good face towards the crowd, she was as cold as ice, and her words always had thorns, which made everyone very angry.
"When a ship goes out to sea, the mast is the last thing that disappears, and when the ship returns, the mast is the first thing to appear. This proves one thing, the sea looks flat, but in fact it has curves.
The same is true for the red and yellow double moons.
When the twilight moon appears, the red moon blocks part of the yellow moon, but how does the yellow moon look different from what we usually see at this time
not at all.
This is because after the sun sets, it is on the back of the world, and the world blocks part of the sunlight, so the crescent moon appears! "
"Impossible, the faint moon is because the light of the yellow moon is blocked by the red moon!" Someone immediately refuted.
Tonglan seemed to be amused by these words, the ice and snow passed away, and her smile spread.
"The yellow moon is shining? I'm afraid you don't even know what the moon is?"
"And how do you explain the curve of the sea surface?"
Although it was difficult for everyone to answer, someone immediately shouted: "In the final analysis, you are just guessing. Without any real evidence, you just take it as a theorem. No matter what, I don't believe that the world is round."
Tonglan frowned slightly, these stubborn guys.
"You Xiaojiang Academy students are just messing around like this?"
"It's because the evidence you said is not enough. The arc of the sea alone cannot explain everything." Cao Gui couldn't help but take a step forward and speak.
In any case, he couldn't accept that the other party belittled the academy like this.
But after he finished speaking, he turned his head and glanced at everyone: "After listening to Miss Tong's speech, where have you been studying for so many years?"
Tonglan rubbed her brows: "As 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 shine
In the dark, put a stone on the ground, can you see
You can see only when there is light.
Specifically why, this involves the principle of light...
But one thing you can understand as long as you think about it, if the moon cannot shine, then the sun is at the back of the world, part of the light is blocked by the world, and the other part of the light shines on the red moon and the yellow moon, so you can see the curved moon. moon.
It is precisely because the world is round that we see a crescent moon. "
"Even so, maybe the world is like a plate, and it's not really round."
"So there's the curve of the sea, and the curve of the earth's surface. Adding these two points proves something."
Tonglan explained frantically that Shi Yu brought everyone from Zhitai Academy here.
"What are you discussing?" Shi Yu asked curiously.
"Tell them again that the world is a ball!" Tong Lan said with a depressed expression on her face.
I knew I wouldn't talk too much, but so many things were involved.
"The world is round?" These words caused many women in Zhitai Academy to exclaim.
Seeing Tonglan's troubled look, Shi Yu thought it was a little funny. Ignoring everyone in Zhitai Academy, he said to Tonglan instead: "Let them go to the sky and see the curve of the earth with their own eyes?"
"in the sky?"
"Can you see the curve of the earth?"
The students of the two academies were immediately attracted by this sentence.
"You mean to be able to go to the sky? How to go up? What is the sky like?"
"Let me ask you, borrowing Mr. Li's hot air balloon, I can take you to the sky." Shi Yu smiled to everyone.
"That's his lifeblood!" Tong Lan snorted softly.
"He's not that stingy, and don't forget the airplane we're researching, that kind of hot air balloon has been eliminated." Shi Yu patted Tonglan's arm and said.
Next to it, people from Xiaojiang Academy are still telling people from Zhitai Academy what Tonglan said about "the world is a ball".
After all, there are many women in Zhitai Academy, who are full of intellectual aura, which makes many students in other academies unavoidably eager.
Shi Yu turned his head and took a look, stood beside Tonglan and said: "It is said that there will be lectures in the next few days, and there will be people from all academies to give lectures. You ghost didn't say anything to us, but we can talk about this The world is round."
"At that time, I'm afraid those people will explode again." Tong Lan snorted softly, she felt troublesome with dozens of people, let alone hundreds of people.
"Do you think they will tell the students of other academies when they go back?" Shi Yu laughed. Although she didn't have the exquisite beauty of Tonglan, she was still above average.
There are no ugly women in the ancient tribe.
After the people on the other side had said about the same, and finally calmed down, Tonglan said with a blank expression: "Go back and ask if I can let you go to the sky to see. It's useless to talk about this topic now, today's tour is not over yet, let's go. "
In addition to a few academies, there are various laboratories and workshops.
These laboratories are different from the previous chemistry laboratories where students learn about chemical reactions. The latter laboratories are all places where new technologies are being developed.
Although the most high-end technology is in the laboratory in Mount Zhongshi, with hundreds of scholars who were kidnapped from the earth and dozens of sword masters, the research in these laboratories in the academy is not simple.
For example, an airplane.
The progress of the aircraft, including engines and other technical reserves, and the overall design of the aircraft, has probably reached the level of World War II.
However, the students in the college are also researching their own aircraft.
Of course, the engine drawings are provided by Zhongshishan Laboratory.
Still, what these students did would put most people to shame.
