This is a beautifully decorated auditorium with a large space inside, enough to accommodate thousands of people. Red chairs are arranged in a circle, forming an overall staircase shape. Even the wizards sitting in the back can clearly see the debate scene.
Philip led Lynn and a few others to sit down at the long table belonging to the Iyeta School.
But unlike before, this time they were arranged to sit in the back seats. Philip knew very well that this was due to the impact of Master Hellram's death. Yieta was no longer a magic school with great wizards.
As soon as the two of them sat down, today's seminar began quickly.
Among the people responsible for presiding over the meeting, Raphael and Auguste were among them.
The first person to come on stage was a tall male wizard. After signaling to several great wizards, he looked at the wizards present and spoke.
"Everyone, I am Artos, the shaping mage of the School of Sky and Wind. Next, I will demonstrate a new flying magic to you..."
As he spoke, the wizard turned around and, amid the screams of the ladies, took off his shirt, revealing his muscular back muscles.
Then a wave of magic spread out from his whole body, and the muscles on his back began to deform and extend from near his shoulder blades, and a pair of huge wings that were three meters long appeared in front of everyone.
However, unlike birds, the wings that Athos transformed were bare and had no feathers, like a very thin and wide membrane.
"I made this type of wing based on the transformation of a bat's wings. It is very light and will not add too much burden to the body. It can become very wide and support the weight of the entire body..."
After explaining a few words, Artos flapped his wings vigorously, and after a few quick sprints, he flew directly up, walked around the seminar hall a few times, causing bursts of exclamations.
"It's a very sophisticated shaping magic, and the deformation is perfect, but flying like this is too slow and too strenuous." Philip in the audience shook his head and was not very optimistic about this magic.
Lin En also nodded. First of all, the human body is not light, and flying by flapping wings requires a lot of physical strength. Secondly, this magic requires a high level of attainment in plastic surgery.
Those wizards who are truly proficient in shaping magic can consider transforming into a Dorgaard falcon directly when they want to fly, rather than simply getting a pair of wings.
Just as the two thought, after Artos explained the details of magic research and development, several great wizards gave low evaluations and finally defined it as an unpopular three-ring shaping magic.
Artos walked off the stage with a sigh. He knew that he would not be able to get the Morning Star Medal this time.
Over the next hour, wizards from more than a dozen schools took turns to explain the new theories they had discovered or the new magic they had created.
In the end, only one potion master, relying on a potion that could quickly replenish the wizard's physical strength, won the recognition of many great wizards and was nominated for the Morning Star Medal.
Taking advantage of this opportunity, Philip also explained to Lynn the three major awards in the wizarding land.
They are the Morning Star, the Silver Moon and the Solar Corona!
The Morning Star is looking for wizards who have researched and improved new magic, potions, and alchemical formations, and several of them are handed out at annual seminars.
But not all magic counts. For example, the improved magic demonstrated by Athos just now is not even eligible for nomination due to its limited scope of application.
The requirements for obtaining the Silver Moon Medal are even more stringent, and it will only be awarded to wizards who have made outstanding contributions in a certain field of magic.
Even the great wizard Adela, who founded the theory of fire element twenty years ago, did not receive a Silver Moon Medal because this theory had not been truly verified.
As for the Corona Medal, it is the highest magical academic award in the entire wizarding land!
Only those wizards who have founded mainstream disciplines and have had a profound impact on the magical theory system of the wizarding land can be nominated for the Corona Medal!
"If you can prove the planetary theory and correct the star map of the prophecy school in the debate this time, you may be able to win a Silver Moon Medal..." Philip said with anticipation and excitement.
The Silver Moon Medal is an honor that only a very small number of great wizards can obtain. When Helram was alive, the Iyeta School was unable to obtain such a high honor.
Lin En didn't care about the awards or anything, but turned his head to look at the seats of the School of Prophecy not far to the right. Several witches and witches had stood up and walked towards the podium.
The leader was wearing a grey robe, his face was slightly thin, his eye sockets were sunken, and he looked like he had not slept for several nights, but he was extremely excited. He looked at everyone and spoke in a high-pitched voice.
"Masters, gentlemen and ladies, I am Yolande from the School of Prophecy. However, I am not here today to explain new astronomical research results. Instead, I have some questions that I hope Mr. Lin En from outside the Land of Wizards can answer for us."
Although Yolande's words were not sharp, everyone could hear the sharp tone.
All the wizards looked in the direction of Lin En, with amused expressions on their faces. They all guessed that the Prophecy School would definitely refute Lin En's planetary theory in public at this seminar, but they didn't know how the other party would respond...
Chapter 138: Of course I have evidence of the planet's rotation!
Under the gazes of countless people in the conference hall, Lin En stood up calmly and walked towards the podium.
"Professor, should he be able to hold on?" Alok muttered to himself. Those wizards from the school of prophecy seemed to be numerous and powerful, and they looked like they were going to overpower others with their force.
Philip was also a little worried. He had wanted to go out together, but was pushed back by Lin En.
When Yolande saw Lin En walk onto the stage, he asked impatiently.
"Mr. Lin, I have read your theory. According to your theory, all the stars, including the continent under our feet, revolve around the sun, right?"
"To be precise, the planets in this galaxy revolve around the sun." Lynn corrected the mistakes in Yolande's words.
Yolande ignored the difference and said with regret, "But I found that you seem to have overlooked a very important issue!"
"What's the problem?" Lynn asked curiously.
"Since you mentioned in the Magic Daily that the period of this continent under our feet orbiting the sun is 360 days, which is exactly one year, how should the phenomenon of day and night alternation be explained? Could it be that only one day and night passes in a year?" Yolande questioned.
According to the theory of the prophecy school, it is precisely because the sun revolves around the continent with a period of one day that there are rising and setting of the moon, and day and night.
Lin En was speechless. He thought Yolande was going to say something very high-end, so he immediately explained with a smile on his face.
"It's very simple. That's because the planet under our feet is not only rotating around the star, but also rotating on itself all the time. This is why we see the alternation of day and night."
Lin En stretched out his hand and created two water balls of different sizes in the void, letting the smaller one revolve around the larger one while rotating on itself. Each rotation represented the alternation of day and night.
"Rotation?" Yolande was stunned for a moment. He didn't expect Lin En to come up with such an explanation, but he soon laughed.
"I have to say, your theory is very interesting. But if, as you said, the continent under our feet is rotating non-stop, or even moving around the sun, then why aren't we thrown out directly?"
Yolande raised his voice a little, and the sound continued to echo in the auditorium.
All the wizards present were discussing the issue, and even the wizards who originally supported the planet theory began to waver under such sharp questioning.
After all, Yolande's words are easy to imagine. For example, if you put a grain of rice on a ball and then rotate the ball rapidly, the grain of rice will inevitably be thrown out.
What's more, the continent beneath their feet is so huge that once it moves, it will inevitably produce extremely terrifying power. Even if they are lucky enough not to be thrown out, they should definitely be able to sense it!
Philip was as anxious as an ant on a hot pan, as if he was the one being targeted on the stage.
Lin En's expression remained unchanged, and he asked with a smile, "You should have worked in a carriage, right, Mr. Yolande?"
"Why are you asking this?" Yolande said hesitantly.
Lin En did not answer but turned to look at the wizards at the seminar, "I think everyone should have noticed that when the carriage is moving, we can only feel the body swaying most clearly at the beginning and end. At other times, we feel the most the bumps caused by the carriage driving over the uneven road surface."
"That's because we are in the carriage during the ride, and due to friction, we move with the carriage. Of course, because the speed of the carriage is sometimes fast and sometimes slow, it is not intuitive enough..." Lin En said, suddenly turning his head to look at several great wizards. "I think Master Raphael and Master August, who have ridden in an airship, should have a better understanding of this!"
Everyone's eyes immediately turned to Raphael and August. After a moment of contemplation, the two nodded in unison.
Unlike a carriage, the airship was completely floating in the air. With the help of a windproof magic array, it traveled very smoothly. They could hardly feel that they were moving so fast on it.
"The same is true for this planet! Previous free fall experiments have proved that the resistance we feel is based on the existence of elements. Under the influence of gravity, all elements and matter change their positions along with the rotation of the planet, so of course we can't feel that we are moving. If one day it suddenly stops rotating, we will probably all fly out..." Lynn said jokingly.
"Nonsense!" A red-haired witch beside Yolande shouted loudly, interrupting Lin En's words. "Lord Harrof once flew to the top of the world. If the continent under our feet is really rotating, then Lord Harrof should have flown to other places with the rotation of the continent in such a long time..."
"The influence of gravity is very large, ma'am, much larger than you can imagine. It is so large that even if we rise to an altitude of hundreds of thousands of meters, we cannot escape its control!" Lin En said lightly, then looked at everyone and spoke loudly.
"Just as we cannot perceive that the planet under our feet is round, the planet's rotation speed is very slow compared to its huge size, and we are as small as dust, just like an ant building a hole in a hill. To it, this hill is the whole world."
The discussions in the hall became more and more intense. Some people agreed with Lin En's theory of planetary rotation. After all, it could well explain the problem of day and night alternation.
However, more people still have deep doubts. According to Lin En, because they are rotating with the planet, they cannot perceive that they are also rotating?
This is outrageous!
Not magical at all!
"Where's the evidence? What evidence do you have to prove that the continent beneath our feet is rotating? This is all just your fantasy!" Yulande sneered sharply. "According to your theory, aren't we also running along with this continent when we sleep at night..."
“Then did you move by yourself when you were riding in the carriage?” Lynn asked with amusement.
"Of course..." Yolande paused. He wanted to say that he didn't move, but when he thought about it carefully, he realized that he was indeed moving.
This contradictory feeling made Yolande, who didn't know what a reference frame was, confused. In the end, he could only conclude that he did not move, but the carriage moved him.
But this conclusion undoubtedly proved Lynn's rotation theory. Yolande was troubled for a long time and did not speak.
"As for the evidence of the planet's rotation, of course I have it!" Lin En ignored Yolande who was in a dilemma, but looked at the seat of the Iyeta School and spoke.
"Johnny, Alok, Pierce, bring up everything you prepared!"
Chapter 139 Lynn's Pendulum Experiment
"Okay! It's finally time for us to take the stage."
Alok and others who had been watching from below for a while were already excited. After getting Lin En's approval, they immediately ran to the platform carrying a large box.
Yolande moved forward to take a look with some uneasiness. The big box was filled with some strange things. The most conspicuous one was a big iron ball with a protruding sharp needle embedded at the bottom.
"Masters, please allow me to use magic to make some changes here, so that the effect of the experiment can be more intuitive!" Lin En said.
"If you think this can help!" Raphael nodded and agreed.
Lynn immediately used the [Turn Fossils into Mud] skill to transform the large stone bricks under his feet into fine sand. Then he asked Johnny and the others to piece together the stone slabs in the box to form a giant disc on the outside of the platform.
There are precise three hundred and sixty scales on the corners of the disk, and a wooden stick is placed in front of each scale.
Finally, Lynn asked the wizard who had previously developed the magic of flying to hang the iron ball on the ceiling of the seminar hall with a steel rope.
Due to the need to demonstrate magic, the hall of the entire magic seminar is not only wide but also built very high, with the ceiling being a full sixty meters from the ground.
The iron ball weighing thirty kilograms was tied to the sand only ten centimeters away with a thin steel wire rope, and the protruding sharp needle at the bottom had sunk into the sand.
"What are you going to do?" Yolande was completely confused. He couldn't understand what the other party was doing at all.
The rest of the wizards on the field also had confused expressions on their faces.
"Let's do an experiment!" Lin En waved his hand and asked Elrok and the others to stand aside, then asked, "Mr. Yolande, what do you think will happen if you push this iron ball hard?"
"Is there any need to explain that the iron ball will be thrown out and then swing back and forth in a straight line?" Yolande responded impatiently.
"I don't think so." Lin En shook his head, "Because you overlooked a very important factor, that is, the continent under our feet is rotating, and the resulting Coriolis force will inevitably affect the swing of the iron ball. Therefore, when the pendulum swings, it will constantly deflect and rotate around the disk."
"Ridiculous!" Yolande didn't believe in the so-called Coriolis force, let alone such an outrageous thing as the rotation of the continents. It was a complete fallacy!
Thinking of this, Yolande stared intently, fearing that the other party would play some tricks during the experiment.
Lin En didn't even use magic. Instead, he pulled the iron ball to the zero scale position on the sand table and then let go of it, allowing the iron ball to swing freely with the help of gravity.
The nearly 60-meter-long steel wire rope was stretched straight by the weight of the iron ball. Under the influence of gravity, it created a gust of wind and hit the 180-degree wooden bar on the opposite side.
