Annick looked at his teacher on the podium nervously and stubbornly. For him, who was shy and introverted, standing up to object to his teacher's explanation was like jumping from Allyn to the ground without any magic effect. However, his mind was shouting louder and louder about the understanding of the microscopic domain, which made him summon his courage and do something that he would never consider at all!
Would his teacher be angry? Would he be disappointed? Would he be infuriated?
Looking back at Lucien without flinching, Annick discovered, to his surprise, that there was not the slightest anger or disappointment on his teacher's face. It was peaceful and deep, without the slightest ripple.
"What do you think is the problem?" When all the arcanists watched the argument between the teacher and the student with different feelings, Lucien nodded and said peacefully.
Annick took a deep breath. "Observation can indeed change the result, but observation cannot be explained as the influence of consciousness or the observer who can think. Observation is an objective behavior. Intelligent lives can do it, common cats and dogs can do it, experimental devices can do it, and the microscopic system made of abundant particles can do it. As to what scale the quantum superposition state exists, it remains to be explored and studied further."
He only had a vague idea that could not be expressed accurately.
"I think so, too." Sprint found that Annick was not so nervous that he could not speak clearly. He basically explained the ideas that he and Annick usually discussed, so he agreed loudly.
Douglas also nodded slightly. "Although there is no accurate mathematical model to support it, it is a more objective explanation. Lucien, your theory is too subjective."
Fernando did not say anything, but the expression on his face suggested that he was on Annick's side. Of course, it was not that he accepted their explanation without any experiment results and mathematical models, but in comparison, Lucien's theory was even more ridiculous!
Brook, Oliver, Hellen, Hathaway, Bergner, Raventi and the rest of them showed the same attitude in different ways.
"But in such a case, how do you explain magic? How do you explain divine power? How do you explain the power of faith? Annick, your explanation does not leave a place for supernatural power. "Lucien still maintained his gentle attitude.
Annick opened his mouth and meant to refute, but he did not know where to start.
"Lucien, don't tie two unrelated problems together. There is no place for magic in the microscopic domain, but it doesn't mean that there is no place for magic in other domains." Fernando said solemnly.
Lucien put on a smile. "My theory is just a conjecture for now, a conjecture that includes all supernatural powers. It is a waste of time to argue in an empty situation. So, let's explore and experiment slowly, hoping to find the truth of the world.."
Huh? There was no telling whether the arcanists were disappointed or relieved. Mr. Evans did not announce his victory with irrefutable experiments and theoretical predictions. It was illogical!
That's not right, this is the normal situation!
Suddenly, Lucien looked at Oliver, Fernando, Douglas, Annick, Sprint and the rest of them with a casual smile. Then, he changed the topic. "I have three unattainable experiment ideas here. I hope that we can complete them with our joint efforts. They will provide powerful evidence for our explanation of the microscopic domain."
"For the first experiment, we all know that temperature is a reflection of the thermal motion of molecules. So, as long as the motion of microscopic particles is restrained, theoretically, the coldness that is closer to absolute zero will be created. In such a restricted environment, the microscopic particles may be in the same quantum state. In the meantime, it will allow us to complete many ideas …"
Lucien roughly explained the idea of creating 'traps' to trap microscopic particles with powerful magnetic fields or lasers. He also 'guessed' how to observe the quantum superposition state of specific microscopic particles in a very short moment through appropriate experiment procedures in such an environment. He did not have any specific ideas and was only a theoretical speculation.
Every arcanist was familiar with powerful magnetic fields. Lucien proposed the concept and the basic mechanism of lasers soon after he learned Vengeful Gaze. Many sorcerers had some understanding about it, because as long as they were equipped with magic stones such as rubies, their ray spells could be amplified to some extent and generate scorching heat. Of course, there was the limitation of distance.
Therefore, after hearing Lucien's description, the sorcerers did not have much trouble understanding it. Hellen did not even blink her eyes. It seemed to have explained a lot of things that she did not understand about ice and snow legendary spells. As for how to create 'traps', even if Lucien had an idea, he certainly wouldn't say it out loud and would wait for his own research!
For the grand arcanists, the direction was more important than any specific steps!
Oliver's face was more or less gloomy, but he was also rather excited. If the real quantum superposition state could be observed, it would be enough to prove that the secrets of demigods were indeed in the microscopic domain! However, the experiment that Lucien described was too difficult to be completed in a short time.
"However, it is of no use to explain the transition from the microscopic domain to the macroscopic world. It only proves that the quantum state is a mixture of many possible states …" Annick and Sprint attached great importance to the experiment that their teacher described, which could help them confirm the wonders of the microscopic domain. However, they were also confused and did not think that it was their teacher's style.
Lucien did not give them much time to think. He continued, "In the magic experiment just now, we can make two more changes."
"The first change is that after the electron self-interferes through the double slits, we will decide whether we want to see its wave nature or its particle nature. So, before it falls on the screen, we will process the screen for that purpose. What kind of experiment image will be displayed at that time?"
"Is there a problem? Since the electron has passed through the double slits, it must've interfered with itself. It must've been the wave nature … "The arcanists thought subconsciously at first, but then they shuddered. Anything could happen in the microscopic domain that was so weird that it defied common sense. Would their observation change the fact that had already happened? So, the law of causality on the timeline was no longer strictly established?
Lucien intentionally twisted the description of the experiment, in case somebody completed it too early and blew up their head. Then, he continued, "The second change is to record which gap the microscopic particles have passed through in a way that does not disturb them. However, this time, after the recording, the experiment device will not send out alarms or other signals to let us know. Instead, it will delete the 'observation record' immediately. Then, will the electron show the wave nature or the particle nature?"
Annick's face turned pale again. Was it to distinguish whether it was the experiment device's observation or "their" observation?
After describing the three experiments, Lucien took a deep breath and said, "That's all for my public class. Do you have any questions?"
The arcanists were still dwelling in the shock caused by the three experiments. None of them answered for a moment.
Douglas thought for a moment and said peacefully but firmly, "I have a thought experiment, too. According to your explanation, before the observation, the microscopic particles are in the form of a cloud of probability where many possible states are superimposed. Then, assuming that the particle changes into two smaller particles and leaves in different directions, there is no observer involved in the process. Therefore, the two particles are also in the quantum superposition state, and the overall conservation is maintained."
"When the distance is long enough, one of the particles is observed, so its state is fixed, and the other particle immediately collapses into a fixed state according to the corresponding law. Does such a long-distance action violate the special theory of relativity? "
The arcanists felt that their heads were dizzy and their blood was freezing. They had experienced too many thought experiments today, from Oliver's cat, Lucien's delay experiment and "delete" experiment, and Douglas' entangled particles. They were all thought experiments that could destroy their worldview. They did not understand much, and they were full of fear.
"I predicted that such a phenomenon would happen, but it does not violate the special theory of relativity, because before the observation, the microscopic particles spread out in space according to the wave function and are everywhere. The two particles are an inseparable whole." Lucien's answer was not very accurate, and he did not dare to be too accurate.
Douglas nodded, not surprised. "I'll try to verify the experiment and see if your theory is complete."
After that, the public class that was destined to be recorded in the history of magic was over. Lucien walked out of the grand classroom and rubbed his eyebrows, somewhat tired, before he returned to his library.
Soon, Heidi, Layria, Katrina and the other students knocked on the door and came in. They asked questions about the microscopic domain.
After a few simple questions, Heidi smiled embarrassedly. "Master, are you not angry?"
"Why would I be angry?" Lucien asked curiously.
Heidi pointed at the door. "Annick and Sprint did not dare to meet you, fearing that you would be angry because of their opposition. After all, the Lord of Storm and the Lord of Elements were against you, but they did not support you!"
Lucien shook his head with a smile. "No, on the contrary, I'm very happy."
"Huh?" Katrina and the other girls looked at their teacher in confusion.
"In the field of arcana, what we adhere to are the results of experiments, observations and theories that are strictly based on those foundations. We do not believe in any person or authority." Lucien said solemnly, "Although I've been in the right position since I joined the Congress and I've subverted one theory after another, other people should blindly believe in me and not refute me when I propose absurd and illogical theories?"
"That's the most wrong arcana attitude! Master and Mr. President refuted and roared at me when I proposed probabilistic explanations, the uncertainty principle and the observer effect, not because they were stubborn, but because they insisted on their own arcana knowledge, which is also rooted in the results of experiments and phenomena. As long as they did not blindly deny the facts of the experiments but looked for other reasons to explain it, it did not matter. "
"If they simply believed in me and agreed with me, they couldn't have become grand arcanists at all. It was the right arcana attitude that Annick and Sprint insisted on their own ideas before I provided any evidence." Lucien taught the students a lesson on arcana attitude by the way. Then he shook his head and smiled. "You think that I'm right, so you think that they are stubborn and reckless when you see them roaring and objecting?"
"Perhaps, I'm really wrong?"
Hearing Lucien's question, Heidi laughed dryly. "After all, I've already lost my head because of the microscopic domain. I've decided to focus on artificial intelligence instead of the destructive explanations."
Layria, Katrina and Chelly also nodded. To some extent, their heads had been blown up.
