Greetings, Mister Principal: Baltic Conference (Part 2)

It takes a genius to remember the address of this website in one second: (Dianping Chinese), the fastest update! No ads!? Sure enough, this half-dead cat appeared.

Reiner was a little emotional, but did not flinch.

On Earth, this thought experiment proposed by Schrödinger has been a sword of judgment over quantum mechanics for a long time. It represents an irreconcilable contradiction between logical common sense and mathematical hypotheses.

Because objective laws and facts are not subject to human will, that is, regardless of human observation or not, the life and death of a cat is an established fact and will not change due to observation. However, Schrödinger’s cat shows that in In the quantum world, the life and death of a cat is determined by human observation. When observing this behavior, the life or death of the cat is also determined. This is a huge contradiction.

Even derived from this, in order to explain Schrödinger's cat, some scholars proposed the parallel world theory, that is, the cat is not a superposition of life and death, but two worlds are derived from this, and the cat in one of the worlds is dead. The cat in the other world is alive.

But such an assumption violates the razor principle, that is, it adds many unnecessary assumptions in order to explain a phenomenon. Therefore, it only exists as a possibility and has not been accepted by the public.

And Schrödinger himself, inexplicably got the nickname of a cat abuser amidst all the jealous jokes in later generations.

Reiner originally expected that a mage would ask similar questions, but he didn't expect that even in this world, the one who was put into the box was not a rabbit or a puppy, but the unlucky cat. Look. No matter where in the world it is, this poor cat cannot escape the fate of becoming the focus of debate among scholars.

Turning our attention back to the problem, Mr. Braggs’ hypothesis has a very tricky point. According to Reiner’s previous explanation, the reason why macroscopic objects do not show quantum effects is because the wavelength of their Ingle waves is relatively small. Since its size is too small to cause fluctuations, Mr. Braggs used an independent quantum system as a switch to affect the state of macroscopic objects through the uncertainty of the quantum system itself, thereby reducing microscopic quantum effects. Expanded to the macroscopic world.

Leiner was first extremely surprised. You must know that none of the mages present had any knowledge about quantum theory before. They did not even consider the related issues in depth until they saw Reiner. ’s paper, they had a qualitative understanding of this theory.

His Excellency Braggs, in such a short period of time, has completely digested the theoretical connotation proposed by Reiner, found possible problems and contradictions in it, and proposed a quite mature thought experiment.

Reiner has always believed that legendary mages are knowledgeable. This kind of knowledge is not limited to magic, but lies in understanding. This is the ability to absorb and understand new knowledge, and to summarize. It can be said that even if these Legendary mages travel to a world without magic, and they can quickly learn the knowledge of that world, quickly adapt and make achievements.

However, Mr. Braggs’ hypothesis, this half-dead cat has one biggest flaw.

Reiner thought that he had naturally considered the question about this cat and had his own answer, so he answered.

"Your Excellency Braggs, Excellencies, I have my own explanation for this issue."

He looked directly into Lord Braggs' eyes without any doubts or hesitation.

"For an atom that may decay, this is a microscopic quantum system. Whether it decays or not can be expressed by a wave function, while the life and death of a cat is a macroscopic system, and the state of the macroscopic system does not apply. Quantum theory, the key contradiction of this hypothesis is that changes in the microscopic system cause changes in the macroscopic system, thus extending the microscopic quantum system to the macroscopic quantum system, and this is why such an incredible conclusion is derived."

Your Excellency Alberton's fingers tapped rhythmically on the table, and the subtle sound echoed in the quiet conference room. He looked at Reiner and was thinking at the same time in his mind.

"My point of view is that this is actually a microscopic quantum system, not a quantum system that combines macro and micro. From beginning to end, it is the micro particles that produce quantum effects, not that one. Cat, the life or death of that cat is not determined by the macroscopic system it is in, but by the atoms that may decay. Therefore, in essence, the wave function of the cat's life and death is the wave function of whether the atom decays."

Reiner explained that with a wave of his hand, the projection of the imprisoned kitten floating on the table suddenly changed. The kitten disappeared and was replaced by a shining atom.

“We can change the conditions of this experiment, take out the innocent kitten, and put in an atom. The properties of this atom will change due to the particles released by the decay of other atoms~IndoMTL.com~ In this system, this problem is very intuitive."

The same structure, except that the original cats were replaced by atoms. The entire system seemed to be quite consistent with Reiner's original hypothesis. It was through this replacement that the mages were suddenly awakened.

The problem with this thought experiment is that it uses the method of transmitting experimental results to demonstrate. If it is established, then it can actually be extended to the entire universe. However, such an argument method is obviously impossible to establish in the experiment.

To explain simply, whether an atom decays is the cause, and the cat's life or death is the result. Decay itself follows quantum theory, and then a result is obtained. This result determines the cat's life and death, and wave function collapse actually exists in The microscopic system of decaying atoms has nothing to do with the cat in the macroscopic system.

If such an experiment really happens in reality, then it is true that the life and death of the cat cannot be determined before opening the box. You can even use a wave function to describe the life and death of the cat, but the life and death of the cat will not change due to observation. It conforms to the principle that objective laws are not subject to human will.

"I still have a question. According to the quantum hypothesis, even if it is an objectively real object, its existence is determined by probability. It is just because its scale is too large and is not affected by collapse. In addition, Ian According to Gray's Uncertainty Principle, our measurement of particles can only be described by probability, but I think the world should not be so random and disordered."

Her Excellency Calvados said that she focuses on the laws of the entire world. The field of astrology she studies does not allow the existence of thoughts that determine matter with such probability.

"Reiner, this world doesn't play dice."

Hearing what the other party said, Reiner smiled slightly and then answered.

"Your Excellency Calvados, please don't tell the world what to do."
