Lin En keenly noticed that their position was obviously a little higher than last time, just behind the Prophecy School, Alchemy Association and other organizations founded by legendary chairmen...
This is certainly an honor, but it is also like putting oneself on the fire. If Yieta does not perform well this time, I am afraid that someone will secretly talk about it behind her back.
"Everyone, please be quiet!" On the podium in the auditorium, the great wizard Sanchez cleared his throat and used the magic of amplifying the sound to transmit it to every corner of the hall, suppressing the noisy discussions.
"Welcome everyone to Greenrill and attend this academic seminar!"
"In the past week, the parliament has received more than seventy proposals on magic theory, which is several times more than usual. Therefore, the entire seminar will last for three days and will be divided into three sessions, all held at noon every day..."
Sanchez briefly explained the process and changes of the meeting. After a pause, he suddenly looked at Lin En and spoke again with a heavier tone.
"In addition, this year's academic seminar needs to add a judge... that is Master Lin En from the Yieta School!"
Chapter 312: Lin En’s outrageous statement: colors don’t actually exist?
As Sanchez spoke, thousands of eyes in the auditorium immediately looked towards the direction of the Yieta School.
Lin En couldn't help but frown. Raphael had never mentioned this to him before. But before he could figure it out, there was a burst of enthusiastic applause in the auditorium.
Under the attention of everyone, Lin En had no choice but to stand up, walk to the podium, and sit down in the judges' seat. Then he turned to look at Raphael beside him and asked with a little dissatisfaction.
"I haven't offended you in any way, have I, Master?"
Although being a judge at a seminar wasn't a bad thing, the suddenness of the event made Lynn have some bad suspicions.
In the short hour since arriving at Green Ridge, the Iyeta School has received too much treatment and honor. Lin En is very clear that the higher you stand, the harder you fall...
"Of course not, why do you think so?" Raphael asked with amusement.
“You should at least ask me before making a decision on this matter.” Lynn said with a hint of dissatisfaction.
"It was indeed my negligence..." Raphael patted his forehead and explained apologetically.
"Many of the proposals received by the Magic Research Association this time are about new glass instruments. I think you should know more about them than us, so we just discussed it and unanimously decided to temporarily add a judge's seat..."
They had not made such arrangements before because they were not aware of Lin En's promotion to great wizard.
A three-ring wizard is naturally not qualified to judge the research results of a certain school at will, but now that Lin En has made a breakthrough, he certainly doesn't have this concern...
It was also to show their importance to Lin En and the [Society of Secret Arts] that they readjusted the seats of the school.
Speaking of this, Raphael was a little amused. Generally speaking, wizards of Lin's age would all be eager to be in the spotlight, and would not be as suspicious as him.
After Raphael's explanation, Lin En finally realized that he had misunderstood and that no one was deliberately targeting him...
At this time, on the podium, Sanchez finished his lengthy opening remarks, announced the official start of this year's academic seminar, and then walked down the podium to make room.
Several young male and female witches came up impatiently, and after bowing to Lin En and the others, they took out a strange cube made entirely of glass, displayed it in front of everyone, and spoke loudly.
"This is the light dissociation device we developed!"
"Isn't this a prism?" Alok muttered quietly in the audience, and the wizards of the Iyeta School beside him nodded in unison. As early as in the Kingdom of Hadrata, Dean Lin En had demonstrated it to them, but it had not been announced yet.
In fact, they are also conducting research on light, but due to the short time, they have not yet produced any key results.
As expected, the witches and wizards on the stage demonstrated the prism light splitting experiment, but these people's research obviously goes beyond that, there are things they have not yet understood...
"We also discovered that red, green and blue are very important among these seven colors. We can even say that all other colors are derived from these three colors." The leading wizard named Glenn said proudly.
"I call them the original colors. You can say that they are the true colors of light. Everything is actually made up of the three colors of red, green and blue. It's just that the intensity of each original color is different, which is why we see yellow, purple, blue and other colors. When the three colors are consistent in intensity and blend together, white light will appear!"
By rotating the angle of the light separation device, the color displayed will change accordingly.
Raphael and others watched with great concentration, and were very interested in the original colors that several people mentioned. This was a big discovery!
Although light is everywhere, even legendary wizards could not sense the so-called "light element" before. They could only develop magic based on the properties of light and achieve another level of utilization of light.
The discovery made by several people now undoubtedly gave them a preliminary understanding of light. A beam of white light is actually composed of three different colors of light: red, green, and blue...
The discussion in the auditorium grew louder and louder, as everyone discussed this surprising discovery.
The witches and wizards on the platform held up the light dissociation devices in their hands and accepted the scrutiny of everyone. They were very excited. With their research, they could at least get a Morning Star Medal!
Glenn has even started thinking about whether to change the name of his school. He has already decided on the name [Morning Light and Original Color]...
"I think this research is very valuable!" Sanchez was the first to speak, praising it.
Raphael and others also agreed very much and praised Glenn's research results.
Glenn's face was full of pride, and then he turned to look at Lynn, who had not spoken a word.
Glenn felt a mixture of envy, admiration and jealousy towards this famous magic star. This time, their research was made with the help of the glass invented by the other party.
However, the young and ambitious Glenn believed that one day he would be able to develop a magical theory that would be able to change the entire magic system like the other and become a magic star that everyone would pay attention to.
Just as Glenn was fantasizing, Lynn suddenly spoke.
"Your research is very good, but I need to make a slight correction! The three original colors you just mentioned cannot represent the origin or nature of light..."
“And strictly speaking, objects don’t actually have color!” Lin En’s shocking statement immediately raised a wave of doubts in the auditorium.
"Master Lin En, what do you mean? Colors don't exist? Then what are we seeing now?" Sanchez asked in confusion.
Glenn and his companions were also extremely dissatisfied. Light decomposition and original color were the results of their hard work and research, and they had rigorous experiments to prove it. However, they were rejected by Lin with just one sentence.
If color doesn't exist, then doesn't that prove that my research is meaningless...
"Mr. Lin, as an academic judge, it is your job to give your own suggestions and point out the errors and omissions, but it is better not to speak casually about things you don't understand..." On the judges' bench, a great wizard in purple clothes shouted in dissatisfaction.
When Raphael proposed to let Lin En become the judge, he was the only one who spoke out against it. After all, a wizard in his twenties might have good achievements in one or two fields, but the breadth of his knowledge was ultimately insufficient. However, this was the most important thing to become an academic judge!
Chapter 313: It turns out that this world has no color!
Amid the doubts of the crowd, Lin En did not rush to explain, but asked back.
"You all know that light can be reflected, right?"
The wizards in the auditorium all nodded. Reflection is the basic property of light, and most polarization magic uses this principle.
"The colors we see are actually the result of light shining on an object, then being reflected into our eyes and recognized by photoreceptor cells." Lin En explained. "Human sensory cells can only distinguish three colors: red, green, and blue. Since the visible solar spectrum is evenly mixed, it is colorless in our eyes..."
"Wait, Master Lin En, if that's the case, wouldn't everything have the same color under the same light?" Sanchez interrupted.
"Of course not, because part of the light is absorbed by the object, and we only see the reflected visible light..." Lin En said.
To be more precise, it is the light reflected by an object that enters the human eye, is converted into electrical signals on the retina, and is transmitted to the brain through the optic nerve. The so-called color is just a human definition of the visual effect of electromagnetic waves in a certain frequency band of visible light...
Regarding this point, after he mastered electromagnetic force, he verified it in Yieta, so he naturally had full confidence.
Lynn's words echoed throughout the auditorium, and the arguments and discussions in the audience became louder and louder.
"This theory is really... too amazing!" Raphael looked at Lin En and couldn't help but say. "Doesn't that mean that this world is actually colorless?"
In the past, they believed that elements themselves had certain colors, and the objects they combined would show corresponding colors, and light only allowed them to see these colors that originally existed or were attached to the surface of the elements.
However, Lin En's statement is completely the opposite. All colors come from light, and what they see is the light that is rejected by objects, while those that are absorbed cannot be seen?
In other words, a red object is actually not red at all. Instead, it reflects all red light and absorbs light of other colors.
Theoretically, if we could find a way to 'see' the 'light elements' inside an object, this thing should appear as a mixture of other colors?
Raphael had a hard time understanding Lynn's words. It was really hard to imagine a world with reversed colors.
"That's right, without light, there is no color." Lynn nodded, agreeing with Raphael's words.
"This is simply absurd!" The great wizard in purple slammed the table and stood up, shouting loudly. "So everything we see is the opposite, a black object absorbs all light and is actually very bright, but we can't see it?"
"No, that's not the case. Since the light is absorbed and not reflected, it naturally won't light up." Lin En shrugged and continued speaking.
"And you can think about it, if you stay in a sealed space at night, can you see colors? So colors exist precisely because of light."
Hearing this, Rafael and others were all stunned for a moment. Sanchez frowned, thinking that Lin En's statement was unreliable.
"Master Lin, magic requires rigorous argumentation, not empty guesswork! We can't see anything without light. Does that mean they don't exist just because we can't see them?" Glenn, standing on the podium, mustered up the courage to refute. He was the person who was least willing to believe this argument.
After all, this concerns whether he can obtain the Morning Star Medal. Once it is confirmed that the original color is not the essence of light, but a phenomenon caused by physiological reasons, the importance of his research results will plummet.
However, as Glenn's courage gradually faded away as he argued with a great wizard, who was also the most sought-after magic star in the wizarding land, cold sweat began to break out on his forehead.
His friend beside him quietly pulled his sleeve, signaling Glenn not to rashly contradict the magic star. The other party didn't even need to do anything, just a little expression of his intention would make their future life difficult.
Lynn didn't pay attention to Glenn's slightly sharp questioning, and said with a smile, "Very good rebuttal, you are right, every magic theory needs to be verified by experiments!"
"Now, please seal up the windows and doors of this auditorium... don't let any light in!"
After Lin En finished speaking, the wizards sitting by the windows in the auditorium cast spells together to block all the doors and windows. The originally bright academic seminar scene immediately became extremely dark, leaving only a little light from the top of the tower directly above their heads.
"Who has a mirror on him?" Lin En asked again.
"I have it with me!" Glenn took a step forward and took out a round mirror from his arms. He has been doing experiments related to light recently, so of course he would always keep the mirror with him.
"Very good!" Lynn nodded, then called Johnny over, asked her to stand in front of the platform, and used a round mirror to reflect the light falling from above her head onto the girl.
In the darkness, Johnny's figure was extremely conspicuous. She was wearing a bright red dress, the hem of which swayed gently like a flame.
"Do you know what color clothes she is wearing?" Lynn asked.
"Red, of course!" Glenn replied.
"Can't anyone see this?" Raphael curled his lips, not understanding why Lin En asked such a stupid question.
"Please remember your current judgment! The clothes are red, don't forget it!" Lin En said meaningfully.
Raphael was speechless. Could it be that this dress would turn blue later?
He wanted to see what the other party was up to!
Lin En turned his gaze to the girl in the red dress and said with a smile, "You have a very fair complexion and are very beautiful..."
Johnny didn't expect that the dean would say this in public. He seemed a little shy and uneasy under the ambiguous gazes of the wizards around him.
This is very suitable for experiments...Lin En silently swallowed the second half of the sentence.
"Next we'll need your...light dissociation device!" Lynn walked up and patted Glenn on the shoulder, greeting him.
"What should I do, Master Lin?" Glenn asked nervously, holding the invention in his hand.
"First, decompose the light like we did just now..." Lynn explained the steps to Glenn step by step in great detail. Only after he was sure that the other party understood, he announced that the experiment could begin!
