Lin En pondered for a while and looked at the wizards at the seminar. "I have some ideas about measuring the speed of light, but I haven't verified them yet. It will take a few days to prepare, probably after the seminar, and the possibility of failure cannot be ruled out. During this time, if anyone can accurately measure the speed of light, I will propose to the parliament to award him a Silver Moon Medal!"
"Silver Moon Medal? Master Lin, isn't this too exaggerated?" Sanchez interrupted quickly.
There are two conditions for issuing the Silver Moon Medal. The first is to propose a theory that is sufficient to change a mainstream magic system.
At the last seminar, when Lin En proposed the law of universal gravitation, they had planned to award him a Silver Moon Medal.
However, the legendary Speaker Harof overcame all objections, and Lin En calculated the various speeds of the planets under his feet and used experiments to prove that the planets are constantly rotating and revolving around the sun, which overturned everyone's view of the world. Only then did he receive the more glorious Corona Medal!
The second method is to make a significant contribution to the wizarding land or parliament.
Now he was only measuring the speed of light, not analyzing the properties of light. He felt that one Morning Star Medal was enough...
"I don't think this is an exaggeration. A legendary wizard in the [Arcane Society] once said that compared with optics, existing magic theories can only be described as simple or even crude. It is just an explanation of macroscopic phenomena, while optics is one of the most important keys to uncovering the real microscopic world!" Lin En said solemnly.
The speed of light is different from the speed of sound, air resistance, gravity, etc., which change when you move to another planet.
The same properties as it include the gravitational constant that Lynn had previously measured, as well as the absolute zero, Hubble constant, Planck constant, etc. that have not yet been measured...
These values are not limited to just one planet, but are the laws that govern objects throughout the universe... at least within the visible and cognitive range of humans, they are unchanging!
The speed of light is particularly important, and many famous formulas are inseparable from this constant!
One example is the famous mass-energy equation – E=mc^2!
The E on the left represents energy, the m on the right represents mass, and c is the speed of light. This formula contains the mystery of mass and energy conversion. Whether it is a nuclear explosion or the more powerful antimatter annihilation, this formula can be used to calculate it!
Of course, whether the theory of the constancy of the speed of light is accepted in the world remains a question mark, and all of this needs to be verified through experiments.
Lin En has always wanted to calculate these basic constants, but he had focused most of his energy on the war in the kingdom, which had delayed it.
It can be said that it was only when they began to study optics that they uncovered a corner of the real world, from the orderly macroscopic world to a chaotic and strange microscopic world.
Even though the Federation in the previous life was not able to fully study quantum theory, even a small gain would be enough to accomplish such a feat as interstellar travel...
Lin En's overly straightforward words made the wizards present feel a little difficult to accept. The wizarding land has developed magic for hundreds of years, but the other party described it with just one word: simple and crude. It was really sensational!
“Could it be that this legendary master of the Secret Law Society went insane while studying light?” A great wizard in the audience sneered and said, very dissatisfied with Lin En’s words that belittled the existing magic theory. Although the element of light is magical, it is at best just one of the bricks and tiles that make up the magic building…
The theory of light elements in the wizarding land has gone through decades of development and improvement and has already built a general framework, but it has not yet undergone final verification.
Chapter 317: The grand plan of measuring the speed of light with a thousand-faceted mirror!
Lin En listened to everyone's discussions and doubts, but he did not rush to refute them. After all, experiments are always more powerful than words!
Seeing that the atmosphere on the field had become somewhat confrontational, Raphael quickly spoke up to ease the atmosphere. "Regarding the method of measuring the speed of light and the theory of light elements, let's discuss it privately after today's seminar. Time is limited, so let's move on to the next item..."
Glenn and the others bowed and left with the light dissociation device. About two minutes later, another wizard walked onto the stage to show everyone his research results, a multi-headed lizard corpse and related research reports!
This is undoubtedly valuable, because the multi-headed hydra is rare in the wizard land, so there is currently no detailed autopsy report on this monster.
If a reshaping wizard wants to completely transform into a certain creature, the first step is to thoroughly understand the structure of this creature. Transforming into a magical creature is even more difficult, as it involves magic cells. Even a formal wizard will only choose one magical creature to transform.
"Very good, but your research missed an important thing, that is, the lizard has several heads. Once a wizard chooses to transform this creature, he will face unknown risks, and it is possible that the soul will be separated..." Sanchez said solemnly as he flipped through the report in his hand.
However, although this is risky, it is also the special feature of the multi-headed hydra. Its regenerative ability is incredible. Even if its head is chopped off, it can grow another one. Its combat power is very considerable. If it can be studied thoroughly, maybe in the future wizards of the plastic school will have another option of magical transformation.
Thinking of this, Sanchez asked him to continue his research. If he could solve the risk of deformation or crack the secret of the infinite regeneration of the multi-headed lizard, he would strive for the nomination of the Morning Star Medal for him...
The wizard who was recognized by Sanchez seemed very happy, and his eyes quickly turned to the other great wizards.
Lynn's understanding of shaping magic is still at the elementary stage. He cannot compare with a master of shaping like Sanchez. He can only give the other party some suggestions on dissection and corpse storage from a biological perspective.
The other judges also made comments and added that Raphael strongly disagreed with developing the transformation magic of the multi-headed lizard. After all, splitting the consciousness into several heads was chilling to think about, and it might cause irreparable damage at the soul level.
But in general, several people agree with Sanchez's judgment. If they can continue their research and produce more rigorous results, they will not hesitate to nominate to Parliament.
"It seems that there will be several recipients of the Morning Star Medal at today's academic seminar..." Raphael said with emotion as he watched the wizard walk down the platform.
He hadn't seen such a grand occasion for decades. It must be that Lin En's winning of the highest honor in academia last year had inspired a wave of research among wizards.
However, Raphael had undoubtedly set a flag. After he finished speaking, no new theories or inventions appeared that made them feel bright throughout the entire afternoon.
Lin En was also very disappointed. One of the wizards came up and said that he had discovered the secret of elements, which was enough to overturn the existing elemental system. He looked forward to it for a while, but the other party's argument could only be described as full of loopholes.
But with the lesson from Glenn in mind, Lynn did not refute the theory bluntly. Instead, he pointed out the loopholes in the theory as tactfully as possible and praised the other party for daring to question authority.
The seminar ended in the evening, and almost all the wizards who walked out of the auditorium were discussing the experiment of measuring the speed of light mentioned by Lin En.
There is no way, the attraction of the Silver Moon Medal is extremely strong, even many great wizards may not be able to get such an honor!
Some people even thought maliciously that maybe Master Lin En wanted them to get another Silver Moon Medal, so he deliberately made optics so important.
But such speculation is obviously untenable, because at the meeting today, Master Lin En had clearly researched the theory of three primary colors a long time ago, but he was still willing to nominate Glenn... If he was a person who attached great importance to honor, he would never give up the Morning Star Medal he deserved.
"Glenn, have you figured out how to measure the speed of light?" Outside the gate, a pretty witch looked at Glenn with a sad face and a bit of complaint in her tone. "You shouldn't have rejected Master Lin's kindness just now. You spent several months researching it."
Glenn said helplessly. "Nancy, everyone in the meeting just now can see that Master Lin En discovered these theories a long time ago. I am not the original creator at all. If I win the Morning Star Medal for this, I am afraid I will be criticized a lot."
"It's nothing more than some jealous people talking nonsense. It's not as important as the Morning Star Medal..." The witch named Nancy curled her lips, still a little dissatisfied.
Glenn shook his head and did not continue to argue. Instead, he skipped the topic, straightened his face, and said, "As for how to measure the speed of light... I think we can use Lady Aurora's method."
"But didn't the Speaker's experiment fail?" Nancy asked puzzledly.
"It's just that the distance is not enough!" Glenn said firmly. "As long as the distance is increased tenfold, or even a hundredfold, it will work. This is the dumbest but also the fastest way!"
One hundred times...that means it's at least one hundred kilometers away, can you still see the light?
Nancy muttered to herself.
Glenn quickly described his idea. He had previously used the magnification and reduction principles of convex and concave mirrors to develop a small magic of focusing light, which could gather light to form a more dazzling light.
This way, even if the light scatters when traveling over long distances, it should still be able to maintain an intensity that can be seen by the naked eye.
As for how to achieve a distance of one hundred kilometers, his idea was to let the light refract back and forth continuously!
If one mirror is one hundred meters apart, ten mirrors would make one kilometer, one hundred mirrors would make a full ten kilometers, and one thousand mirrors would make a hundred kilometers!
Even if the speed of light is one thousand kilometers per second, as Aurora guessed, it would still take 0.1 second to travel the entire distance. With the wizard's reaction speed, this accuracy is still barely enough to make a judgment...
"A thousand mirrors." Nancy smacked her lips in amazement, and was impressed by Glenn's ability to come up with such a grand plan, but then she hesitated. "This thing is not cheap..."
A mirror costs several magic gold coins, and even if they emptied their pockets they couldn't afford it!
"So we can only borrow it!" Glenn shrugged. In order for his experiment to proceed smoothly, he had to put aside his pride.
Chapter 318 It seems that Master Lin En has miscalculated this time!
While the wizards in Greenriel City were studying methods to measure the speed of light, a conversation was also taking place in the manor of the legendary Speaker Harrov.
"The existing magical theories in the wizarding land are extremely rudimentary...did he really say that?"
After listening to Aurora's story, Harof couldn't help but frown. Lynn's words were undoubtedly a provocation to the entire wizarding land.
It is also a great disrespect to those pioneers who have worked hard to develop and study magic. Even if you have extraordinary knowledge, you should not be so arrogant.
"No, I don't think he meant just the land of wizards. The magic theories developed by the [Society of Secret Magic] are no exception. They all seem extremely simple in the face of optics..." Aurora explained, while recalling what Lin En said at the meeting.
Optics is the most important key to reveal the real world at the microscopic level...
What exactly does this real world refer to?
Could it be that the world they see now is all fake?
Aurora thought in confusion, but she still understood the meaning of these words.
Harof also fell into deep thought. From the previous contacts and the various novel theories proposed by Lin En, it can be seen that the [Society of Secret Magic]’s understanding of magic and this world is far more profound than theirs.
If these words are not meant to be sarcastic and arrogant, then it is worth exploring what secrets the ubiquitous light contains to deserve such an evaluation...
Harof really wanted to attend another gathering of legendary wizards and ask them in person, but he had not received any invitation until now.
Although Harof, who possessed the [Ring of Mysticism], also had the right to organize meetings with other people, this seemed too hasty. The most important thing was that he had not yet figured out the Big Bang Theory, nor had he been able to come up with any new theories that could be discussed by a group of legends.
Thinking of this, Harof vaguely understood why the gathering of legendary wizards has not been held yet. It is normal for a magical research to take seven or eight years, or even more than ten years to produce some results. An academic seminar held once a year in the Wizarding Land is already considered frequent.
"It seems that we must pay more attention to the study of optics." Harov's expression became extremely solemn, and then he looked at Aurora and asked curiously, "Do you have a way to measure the speed of light?"
Aurora is the one among them who has the most profound understanding of optics. If even she can't do it, then I'm afraid no one in the entire wizarding land can measure the speed of light.
"I think we can start with astronomy!" Aurora said thoughtfully.
What is the most difficult part about measuring the speed of light? Of course, the speed of light is incredibly fast, and they can't find a large enough venue to conduct experiments, and it is also difficult to create strong light that can travel thousands of kilometers.
When it comes to the vastness of distance, it must be the universe and the starry sky!
According to the data they calculated last year, the diameter of the entire planet is tens of thousands of kilometers, and the distance between each planet is even farther. The most important thing is that the sun above their heads is an extremely large luminous body. As long as they know the distance between the two sides, can't they measure the speed of light?
"That's a good method!" Harov said in admiration, but soon he seemed to have thought of something and interrupted him. "No, that's not right. When we see the sun, the light has already arrived. There is no way to measure the speed of light in this way."
According to Lynn, everything they saw was the reflection of light. Before the light arrived, they couldn't see the sun at all, so how could it be used as a reference?
Aurora also frowned. She had not considered this before, but after just a few seconds, she smiled again. "Then we can try other stars in the distance!"
"For example, the companion star of Tyr disappears from time to time. I think it rotates to the back of Tyr and blocks the sun's light, so we can't see it...
The orbital cycle of a planet should be extremely stable and regular, but this is not the case. According to my observation, the time when the companion star disappears is not uniform in a year. Sometimes it disappears faster, sometimes slower, and it changes every month..."
This strange astronomical phenomenon once puzzled her, but now she has the answer!
Because in a year, Tyr's distance from them in the orbit of the sun is different. It takes time for sunlight to propagate to the companion star and then reflect back to be seen by them. It will not arrive immediately. If the distance between the two stars and the Eternal Star is known, perhaps the speed of light can be inferred!
After listening to Aurora's story, Harov clapped his hands in admiration. "You've got a way. It looks like you've definitely won the Silver Moon Medal this year!"
As he spoke, Harov couldn't help but burst into laughter. This time, Lin En was afraid that he had miscalculated.
Lin En dared to publicly promise to nominate the Silver Moon Medal for the person who calculated the speed of light. Obviously, he was very confident that they would not be able to find a way to measure the speed of light in just a few days. However, the other party obviously underestimated their ability!
"There's just one more question..." Aurora said hesitantly.
"What's the problem?" Harov asked with a smile.
"The diameters and distances of the planets are still being measured. We have only figured out how far the sun and moon are from the Eternal Star beneath our feet. It's not Tyr's turn yet..." Aurora said helplessly.
The method they used to measure the diameter and distance of planets was the three laws of stars and the trigonometric parallax method given by Linn. Due to the large size of the planets, the calculated data was incredible, and they often had to calculate and confirm repeatedly, so progress was very slow.
"It's been almost a year and you still haven't finished the calculation?" Harof's expression was speechless. That was the same as not saying anything. Lin En would verify it after this seminar. They didn't have the time to wait and slowly calculate it.
Aurora rolled her eyes at Harof. They still had to verify the theories proposed by Lin En this year and redraw a detailed star map. Tyr was not very important, so it was naturally ranked lower on the list.
