I made science magic

At the same time, within one tenth of a second, the thermal field emission electron gun emitted another electron.

Glenn, who was watching the experiment closely in the front row, instantly sensed the disturbance in the electromagnetic field. The disturbance was very small, but it was extremely clear due to the huge computing power provided by the magic network.

This 'electron' was lucky enough to pass through the gap on the right and hit the photosensitive screen, and a tiny spot of light appeared at the corresponding position on the screen.

"Really, there is really only one electron!" Anthony was extremely confused. Although they did not really see or sense the electron itself, they observed its general trajectory through the disturbance caused by this thing.

The particles do propagate in a straight line, and the light spots on the photosensitive screen at the rear are solid evidence.

But why do those strange interference fringes, similar to those caused by waves, appear?

Wizards who were as puzzled as Anthony were all very alert. They wanted to see with their own eyes what exactly affected the movement trajectory of electrons.

The thermal field emission electron gun fired non-stop, and under the close watch of Anthony and others, every lucky "electron" passed through one of the gaps truthfully, without the slightest change in the path.

What about the deflection?

If this continues, how are the light spots similar to interference fringes formed?

Anthony's expression became more and more confused, and at this moment a cry of surprise suddenly sounded in the exhibition hall.

"Look, the photosensitive screen... the photosensitive screen... has changed!"

Anthony's pupils shrank, and he noticed that at some point, the pattern on the screen had gradually changed from nine stripes to two...

Seeing this scene, even Harof, Vittorio and Aurora could no longer sit still. Their six eyes were fixed on the changing photosensitive screen, and then they turned to Lin En who was still sitting quietly in the judges' seat.

Lin En shrugged and said calmly, "You can see that my electron launcher is right there, and no one has touched it!"

Chapter 510: Your probability theory is a blasphemy against magic!

Lin En's explanation was very concise, but the wizards present were skeptical.

Because the experiment in front of him could only be described as weird, and all the changes happened after Lin En expanded his domain!

Even Raphael and others who had great trust in this magic star couldn't help but have a doubt in their hearts: could it be that the other party had secretly tampered with the experiment and changed the results?

Although no one expressed this idea aloud, Lin En could see it from everyone's expressions and said it again generously.

"I am the only one who can control the magic network, but it doesn't matter who casts the domain!"

The moment he finished speaking, Lin En withdrew his own territory. He knew that if he didn't let these people try it one by one, no one would be willing to believe that such a counterintuitive phenomenon would really exist.

At the moment the field disappeared, the wizards in the exhibition hall also broke free from their strong perception of the electromagnetic field.

However, no one was in a hurry to use their domain, but everyone looked towards the experimental field at the same time.

The fluorescent screen changed again. The two stripes formed by the light spots gradually dissipated, and nine interference stripes like zebra crossings appeared instead.

"That mysterious interference has started again?!" Sanchez felt as if ghosts were rushing to his body and he was in terrible condition.

The particles are being transmitted along a wave path... This weird feeling that goes completely beyond common sense is really mind-boggling.

"Let me try it." Harof's face was extremely solemn. He was the first to activate the field, and then Lin En connected the perceptions of everyone in the magic network together.

The trajectory of the electrons became regular again...

It passed through the gap obediently and landed on the photosensitive screen at the rear, just like a particle that was accelerated by normal force.

But this kind of normality has become abnormal in the eyes of everyone!

Harof's domain lasted for a minute and then stopped, and he fell into deep thought. Then Vittorio and Aurora also tried it.

"It's my turn this time..." "I don't believe it!" "Let me try it too!"

The great wizards present at the meeting also personally experimented after the speakers, but it was as if the electrons were playing a weird game of hide-and-seek with them, and the photosensitive screen kept changing.

"Could it be the influence of the domain?" Arad couldn't help but speak out.

He suspected that there might be something in the void that could affect the movement trajectory of particles, and this force disappeared after they expanded their domain.

"No, it's not a problem with the field. In fact, before conducting this experiment, I tried it with other instruments, such as installing electronic detection equipment behind the two gaps, and the results did not change anything!" Lynn directly rejected Arad's guess.

The reason for choosing to expand the field is simply to allow the wizards present to "see" more clearly.

"So what exactly affects the trajectory of electrons?" Aurora asked.

"If I'm not mistaken, it's probably... observation!" Lin En responded solemnly.

Observation?

Lin En's answer was beyond the expectations of everyone present. Raphael almost pulled his beard off when he heard this. It took him a while to confirm in disbelief.

"You mean to say that because we were observing the electrons, they behaved as particles, and if we stopped observing them, they would suddenly become waves?"

"No, to be precise, without observation, it has both wave and particle characteristics..." Lynn corrected Raphael's words. "I call it the quantum wave-particle duality!"

"It's really ridiculous. How can something be both a particle and a wave?" A great wizard interrupted angrily. This was clearly an insult to his intelligence.

The wizards in the exhibition hall also found it difficult to understand this so-called wave-particle duality. They simply could not imagine such an existence with their brains.

"This kind of wave is not the mechanical wave you understand. I call it probability wave!" Lin En explained.

The so-called probability wave refers to the probability that a microscopic element may appear at a certain point in space at a certain moment. For example, when an electron passes through the slit, it may fall at any position on the photosensitive screen, but the probability of falling in the interference fringe area is relatively higher.

However, this is without observation. Once the field is expanded and the position of the electron at this moment is confirmed, the electron will then move along the determined trajectory and land on the only fixed point.

"That's really..." Sanchez's face twitched constantly as Lin En explained. He couldn't find the right adjective for a long time, and finally could only squeeze out a few words from his teeth. "It's incredible!"

The probability wave proposed by Lin En is even more bizarre than the wave-particle duality!

This is like telling you that there is an animal whose form can switch back and forth between many species such as fish, horse, donkey, eagle, etc., and has all their characteristics. It can fly when it needs to go up to the sky, and can swim when it needs to go to the sea...

But as soon as you look at it, the shape of this thing will be frozen. Those that can run will not fly, and those that can fly will drown if they fall into the water.

This is even more bizarre than any story. No, it can only be described as outrageous!

"Excuse me for being frank, Speaker Lin, but I cannot agree with your theory of probability... The laws governing the operation of this world must follow clear rules, we just haven't found them." Jeffrey stood up excitedly, his tone, which had been somewhat suppressed at first, soon became louder and louder, and in the end he was almost roaring.

"There is no such thing as probability in this world!"

From the movement of small objects to the operation of large celestial bodies, everything follows specific laws without exception!

This is almost the most basic logic of magic!

After all, the source of wizards' power is to observe, summarize, and replicate this pattern, and reproduce it with magical mimicry!

For example, in the past, when they used magic to attack the enemy, they only needed to confirm the enemy's distance, position, and speed, and rely on their excellent computing power to calculate the trajectory of the attack and achieve a 100% hit rate.

Now according to Lin En, the positions of the microscopic particles that make up the bottom layer of the world are actually determined by probability. Without observation, it is completely unknown whether the enemy will survive and where he can be hit!

Jeffrey simply couldn't accept this bizarre argument!

The wizards present had similar thoughts. This was not just a matter of undermining the foundation of magic, it was a blasphemy against demonology!

“No, you are wrong. Of course there are things in this world that rely on probability, and there are a lot of them…” Lin En took out a gold coin from his arms and tossed it up.

"For example, if we throw a gold coin into the air without any manipulation or magical interference, there is a nearly 50% chance that the front or back side will face up."

"But no matter what, before it completely falls and is observed by us, anything can happen!"

The thrown gold coin kept spinning in the air, attracting the attention of all the wizards. At the moment of falling, Lin En suddenly put his palms together to wrap the falling gold coin in the center, blocking everyone's sight.

"Can you guess which side of this gold coin is facing up now?" Lynn asked with a smile.

Tens of thousands of official wizards in the exhibition hall began to think about it.

Is it the front or the back?

No, it's possible to say both...

"Of course it's the front side!" Jeffrey said with great confidence, interrupting everyone's thinking. Although the two sides were separated by hundreds of meters just now, with his excellent eyesight, he could clearly see the final falling trajectory of the gold coin.

"Are you sure?" Lin En asked again. "How sure are you?"

Jeffrey opened his mouth and was about to say that he was 99% sure, but he soon realized that he had fallen into the trap of the magic star, so he stiffened his neck and said, "As long as you don't move it in any way, I am 100% sure that it is positive!"

He believed in his own eyes, and even more in his own judgment...

However, Lynn shook his head in disappointment and moved his hands away. "Of course I didn't move it, but it's a pity that you guessed wrong!"

Guessed wrong?!

Jeffrey looked over in confusion.

The gold coin fell right in the middle of the table, in the tiny gap between two wooden boards!

"I forgot to say just now that there is still a very small probability that it will stand upright!" An obvious smile appeared at the corner of Lin En's mouth.

Jeffrey's eyes widened. He doubted whether the magic star had secretly used some tricks at the last moment, but he couldn't say it because there was indeed a possibility that the gold coin could stand upright!

Lin En smiled without saying anything and put the gold coin away. As per his promise, he did not interfere in any way after throwing the gold coin.

But this is certainly not due to luck!

His luck is not that good!

In fact, from the moment this gold coin was thrown, it was destined to fall into the gap!

Because he chose a force and angle to throw it that would fall into the gap from countless possibilities, so its fate was determined from the beginning.

He who tossed the gold coin was not only an observer, but also a promoter of fate...

At this moment, Lin En felt that he seemed to have realized something, and his understanding of the quantum field became deeper.

Although Lin En used a gold coin to explain what probability, choice and possibility are, it was obviously not enough to dispel the doubts of the wizards.

"This is different, this is different! If everything in the microscopic world is probabilistic and uncertain, then how do they constitute macroscopic matter? Will the flowers on the ground disappear if I don't go to see them?" Sanchez said in great confusion.

The other wizards also cited various examples to refute the argument, and the exhibition hall suddenly became noisy.

Fortunately, they do not understand what idealism and materialism are, otherwise they would have accused Lin of having very dangerous idealistic thoughts and would have been subject to criticism!

"How microscopic matter forms relatively stable macroscopic matter is a question worthy of in-depth study." Lin En nodded, and did not give a long explanation. Because if all the arguments were thrown out in one breath, it would probably be even more difficult for these wizards to accept.

Lin En only said that these issues will be explained in his upcoming new book [The World of Probability - Quantum Mechanics].

"Everyone, I need to remind you that it is our cognition that needs to conform to the underlying logic of the world, not the logic of the world's operation that needs to conform to our cognition!"

"This is very important!" Lynn said firmly.

The macroscopic world is certain and regular, and this certainty also makes it particularly difficult to understand the laws of the microscopic world.

The so-called probability waves and probability clouds are incredible and even contrary to common sense, but it must be said that it is indeed one of the underlying logics of how the world works.
