The academic seminar lasted for several hours, with wizards constantly taking the stage to explain their inventions or magical theories.
Not to mention other things, there are three models of perpetual motion machines. It is obvious that wizards are very keen on creating infinite power.
The most reliable one is the magnetic perpetual motion machine, which uses more than a dozen permanent magnets to provide power and is expected to be used for more than ten years. However, this thing was still rejected by Lin En.
After all, with these strong magnets, why don't they just use them to make generators?
Wouldn't that be more efficient?
However, wizards' imaginations are not always so flawed. After more than a year, the results of various magic theories can only be described as a blowout, especially in the fields of arcane mathematics, mechanics, elements, and electromagnetism.
In these few hours, Linn, Haroff and others have already given out six Morning Star Medals. You must know that this is only the first day of the seminar.
Sean was the thirty-sixth person to take the stage, and also presented his invention - a mechanical pendulum clock for timekeeping!
Today, the timing method used by wizards is still the hourglass method, which is measured based on the time it takes for quicksand to leak from one container to another.
But the difference is that the magic hourglass made by wizards contains a special kind of sand of time that is enchanted.
This thing has two important characteristics.
The first is that in the special hourglass, it will fall at a speed of ten grains of sand per second. The second is that it is especially obvious under the wizard's unique spiritual perception.
This means that wizards only need to touch the hourglass to know the amount of remaining sand through mental power, and their computing power can also determine the current moment in a very short time.
Its accuracy can reach about zero point and one second.
The mechanical pendulum clock manufactured by Sean uses the isochronous principle of a simple pendulum.
The so-called pendulum refers to a device that can produce reciprocating swings - one end of a string is suspended from the ceiling, and a small ball is placed on the other end to form a pendulum.
Then as long as an initial force is applied to it, the ball below will start to swing back and forth under the influence of gravity.
And according to the rules he discovered, the time it takes for the ball to swing back and forth is only related to the length of the cycloid and will not be affected by the amplitude of the swing. This stability becomes the basis for measuring time...
Sean directly disassembled the entire pendulum clock, pointed to the gears, balance wheel, spring, and hairspring inside, and explained its operating principle in detail.
In short, the force of the pendulum drives the gear, and one rotation represents one minute!
After listening to Sean's narration, Lin En understood that this was a relatively rudimentary pendulum clock. Probably because it had just been developed, its structure was very crude.
After casually pointing out a few areas that needed improvement, Linn spoke again with a smile. "In my opinion, it is better to increase the number of gears inside the dial to three. Each time the small gear rotates, it drives the middle gear to rotate for one moment, and one rotation of the middle gear drives the large gear to rotate for one moment. I call this The wheel of seconds, the wheel of minutes and the wheel of hours!”
Sean paused for a moment, with a look of surprise on his face, and soon understood the benefits of doing this. This way, he didn't have to calculate how many turns the dial had made, and he could tell at a glance what minutes, hours and seconds it was.
"Thank you for your suggestion, Speaker Lin En. I didn't expect that you also have such high attainments in alchemy." Sean bowed slightly and thanked him.
Before he was in the empire, all he heard was how talented the magic star was in magic research, but he didn't expect that the other party was such an all-rounder.
"In fact, Speaker Linn is the most skilled wizard in alchemy in the entire magical world. My title as a magical creator has long been unworthy of my name." Vittorio, who was sitting on the judges' table, said with shame.
Lin En, who built airships, fighter planes, magic trains, and giant steel ships in just a few years, more closely fits the name of a magical creator.
Although the Sunfire Cannon developed by myself is also very sharp, it is just a copy of others' wisdom and the use of alchemy to reproduce [Final End - Atomic Breath].
"Actually, my alchemy skills are very average. At best, I only have some experience in engineering research." Lin En shook his head and smiled. He knew very well that he just had the advantage of being knowledgeable.
Even if he doesn't remind him, Sean can completely improve it through improvement over and over again.
Lynn quickly ignored the topic and instead discussed with Harrouff and others whether Sean should be nominated for the Morning Star Medal.
Several people are very optimistic about this new timekeeping method.
Although its accuracy is not as accurate as the magic clock, its greatest value is that it does not require magic power, which means that even ordinary civilians can use it, and its structure is not complicated, making it extremely popular.
This is an example of using gravitational potential energy, and it is much more reliable than those so-called perpetual motion machines.
Lin En also nodded. In his opinion, the meaning of this pendulum clock is more profound than its function, and it represents the innovation of timing devices.
After gradually deepening the research target into the microscopic field, the magic hourglass with an accuracy of only one tenth of a second seems to be insufficient. It must be accurate to one thousandth of a second, or even one ten thousandth of a second.
The wizard named Sean in front of him may be a good developer of new timers.
In view of this, Linn was not stingy with rewards and directly awarded the opponent a Morning Star Medal.
Sean stood there flattered, watching the magic star hand him the medal, his face flushed with excitement, he had never enjoyed such respectful treatment!
After bowing again to express his gratitude, Sean sat down again while everyone was extremely envious. Several wizards around him even took the initiative to chat with him enthusiastically.
"Then the next one is Master Sanchez's light particle scattering experiment." Harrov looked at the list in his hand and read out.
Hearing this, the wizards present were shocked. They understood that this was the focus of this academic seminar.
The theoretical dispute between light particles and waves has been going on for several months, and this is not just a simple theoretical dispute. It is about the ownership of a corona medal, and no one can give up.
Under the spotlight, Sanchez stood up and walked to the booth. After bowing to the speakers, he elaborated on his theory of light particles.
This is the same as those papers previously published in [Magic Daily]. The fundamental argument is that light is composed of particles, and there are an extremely large number of them. Even within a beam of light with a diameter of 0.1 mm, , the light particles contained are also hundreds of millions!
As he spoke, Sanchez raised his right hand and created a reddish translucent magic ball in the palm of his hand. A large number of mimetic elements were constantly surging inside to simulate the existing form of photoelectrons.
At this moment, a wizard who supported the wave theory suddenly sneered and interrupted Sanchez's words.
"Wait a minute, Master Sanchez, you just said that light is electricity and electricity is light. You even thought that electricity is composed of smaller light particles..."
"Candles that can be lit can also continue to glow. Does this mean that candles can continue to generate electricity?"
There was a burst of laughter in the huge conference room. Of course, candles could not be used to generate electricity... But some people did not laugh, and of course Sanchez did not. Instead, he sighed helplessly.
"I wonder if you are a wizard of the kingdom or a wizard of the empire?"
"I come from Sertod, the City of Steel..." the wizard said with a steady expression.
Sertod is an important city located in the eastern region of the kingdom. It was 'recaptured' relatively late and had been under the rule of the great nobles before.
In the implicit division of wizard groups, they are at the middle and lower levels.
Although everyone is a wizard, the prejudices against each other still exist.
For example, wizards born in the land of wizards look down on wizards born in the kingdom, thinking that they are all barbarians who have not received systematic magic education, while wizards in the kingdom look down on the wizards in the empire...
Even if the Parliament deliberately eliminates regional differences, such contradictions still inevitably arise.
Sanchez also realized that his words might cause some misunderstandings, so he quickly shook his head and said. "In short, I suggest you buy a copy of Master Arad's book [The Nature of Fire], and then take a good look at Speaker Lynn's [On the Internal Structure of Elements, Electronic Orbital Model], so as not to ask such stupid questions again."
"What is fire? It is the oxidation reaction during the combustion of substances. If the temperature is enough, it will be a ball of high-temperature plasma..."
"And electrons exist inside every element. I think everyone should know this common sense..."
Sanchez looked at the wizard with disdain. Let alone a candle, the temperature is theoretically enough to ionize all substances!
Hearing these words, the wizards who had been laughing just now felt extremely embarrassed, and the wizard who spoke was even more speechless.
After Sanchez explained something, he ignored these ignorant people and continued to talk about his particle theory, based on the small hole imaging that Glenn had just demonstrated.
With the efforts of the apprentices, a simple experimental bench was quickly built.
There are only three things on it.
On the left is a candle, in the center is a partition with a small hole, and on the right is a stone wall.
Sanchez lit the candle, and a candle-shaped light spot immediately appeared on the stone wall opposite, but it was upside down.
"We can imagine that the light emitted by the candle flame is composed of countless light points. Since the diameter of the fireworks is larger than the hole, the light points from the upper part of the candle flame pass through the small hole in a straight line and will shine on the bottom of the wall. The light emitted from the lower part of the candle flame will shine on the top of the stone wall, and all the light spots combined form an inverted candle flame!"
"If light is a wave, then it is impossible for it to show such a clear image that is upside down and completely opposite in shape and size!" Sanchez said loudly. "So there is no doubt that light is a particle traveling in a straight line!"
Sanchez's voice continued to echo in the exhibition hall, and the wizards present looked at the conspicuous candle shadows on the stone wall and talked about it.
"Then how do you explain the problem of light interference and diffraction?" Jeffrey, who had been silent all this time, finally couldn't help but speak, and the question was the dead end of the particle sect.
"This is exactly the experiment I am going to do next!" A mocking smile appeared on Sanchez's lips. "Everything will be clear with a simple simulation!"
Sanchez directly asked people to remove the candle and replace the middle baffle with a double-slit one, and then created another blue-light elemental ball in his left hand.
"Now I assume they are photoelectrons!"
Sanchez held up two elemental balls, one red and one blue, and under the gaze of everyone, shot them into the two gaps in the baffle!
After these two groups of particle elements hit the hole with a smaller diameter, the protective film on the outside burst open, and the magic mimic elements inside began to spread in all directions.
Since there were two explosion sources at the same time, and the distance was very close, many scattered red and blue elements quickly collided with each other and merged together, and the power became more powerful.
The wizard in the front row suddenly stood up from his seat, staring at the stone wall.
The red and green mimic elements hit the wall, leaving eye-catching holes. About three seconds later, the results came out. The impact points of the scattering elements were concentrated in several areas, forming nine holes. Streaks formed by impact craters.
It is not that there are no pits in the middle of these stripes, but the number is relatively small.
"Interference stripes, these are interference stripes!" Sean shouted in shock.
More and more people have realized that if these potholes are compared to scattered light particles, then the areas with dense potholes are the areas with the brightest light, while the rest of the places are relatively dark.
In other words, even if the light is a particle beam, light interference and diffraction may occur!
Realizing this, the wizards who supported the light particle theory were extremely excited. Sanchez's experiment undoubtedly eliminated the biggest obstacle to the particle theory. For a while, cheers and applause resounded in the exhibition hall.
The great wizard Arad directly read out the results and shouted loudly. "This is the victory of particle theory!"
Sanchez proudly turned his gaze to Jeffrey and Anthony.
"I have to say, this explanation is very clever, Sanchez!" Anthony couldn't help but sigh.
He had seen the photoelectron explosion theory proposed by Sanchez, but he didn't expect that the other party actually carried out this experiment, even though it was just an experimental result of mimicking photons.
"I'm sorry that you gave up the right path, Anthony." Sanchez said with a chuckle. "It's not too late to repent!"
Anthony shook his head and sighed. "Unfortunately, this theory is wrong!"
Seeing that Anthony was still stubborn, Sanchez frowned dissatisfied, but before he could reply, Anthony spoke again and said decisively.
"Because I have found the essence of light. It is actually... an electromagnetic wave!"
