Chapter 499

Sure enough, there was a cat that would never die.

Lena had some emotion, but he didn't flinch.

On earth, the thought experiment put forward by Schrodinger has become a trial sword of quantum mechanics for a long time, which represents the contradiction between logical common sense and mathematical hypothesis.

Because the objective laws and facts are not subject to the will of human beings, that is, whether human beings observe or not, the life and death of a cat is an established fact and will not change because of observation. However, Schrodinger's cat shows that in the quantum world, the life and death of a cat is determined by human observation. While observing this behavior, the life and death of a cat is also determined. This is a problem It's a huge contradiction.

In order to explain Schrodinger's cat, some scholars put forward the theory of parallel world, that is, cats are not the superposition of life and death, but two worlds are derived from it. The cat in one world is dead, and the cat in the other world is alive.

However, such a hypothesis violates the principle of razor, that is, many unnecessary hypotheses are added to explain a phenomenon. Therefore, it only exists as a possibility and is not accepted by the public.

And Schrodinger himself, in all kinds of embellishment of later generations, also got the nickname of a cat maniac.

Lena had expected that a mage would ask a similar question, but he didn't expect that even in this world, the one put into the box is not a rabbit, nor a dog, or the unlucky cat. It seems that no matter in which world, the poor cat can't escape the fate of becoming the focus of scholars' debate.

Turning our eyes back to the problem, there is a very ingenious point in Mr. Bragg's hypothesis. According to Leiner's previous explanation, the reason why macro objects do not show quantum effect is that the wavelength of the Ian wave relative to its own size is too small to cause wave phenomenon, so Mr. Bragg uses an independent quantum system to do the calculation As a switch, the uncertainty of the quantum system itself affects the state of the macro object, thus expanding the micro quantum effect to the macro world.

First of all, Lena was extremely surprised. You know, before that, none of the mages here had any knowledge about quantum theory, and they didn't even think deeply about the problems related to it. Only when they saw Lena's paper did they have a qualitative understanding of this theory.

In such a short period of time, sir Bragg has completely digested the theoretical connotation put forward by Reiner, found out the possible problems and contradictions, and put forward a fairly mature thought experiment.

Reiner has always believed that legendary mages are knowledgeable, which is not limited to magic, but more lies in understanding. This is the ability to absorb, understand and summarize new knowledge. It can be said that even if these legendary mages go through a world without magic, they can quickly learn the knowledge of that world, quickly adapt and make a decision We have made great achievements.

However, sir Bragg's hypothesis, this half life cat has one of the biggest defects.

It occurred to Reiner that he had naturally considered the question about the cat and had his own answer, so he answered.

"Mr. Braggs, ladies and gentlemen, I have my own interpretation of this issue."

He looked directly into the eyes of Lord Braggs without any doubt or hesitation.

"For an atom that may decay, this is a microscopic quantum system, and whether it decays or not can be expressed by a wave function. The life and death of a cat is a macroscopic system, and the state of the macroscopic system is not applicable to quantum theory. The key contradiction of this hypothesis is that the change of the microscopic system causes the change of the macroscopic system, which will change the microscopic quantity The subsystem extends to the macroscopic quantum system, which leads to such an incredible conclusion. "

Mr. Alberton's fingers beat rhythmically on the table, and the subtle sound reverberated in the quiet conference room. He looked at Lena and thought at the same time.

"My point of view is that this is actually a micro quantum system, rather than a combination of macro and micro quantum system. From the beginning to the end, it is the micro particles that produce the quantum effect, not the cat. The cat's life and death are not determined by the macro system it is in, but by the atoms that may decay. Therefore, in essence, the cat's life and death is not determined by the macro system it is in The wave function of life and death is the wave function of whether an atom decays or not. "

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

"We can change the conditions of this experiment, take out the innocent kitten and put it into an atom. This atom will change its properties because of the particles released by the decay of other atoms. In this system, the problem is very intuitive."

In the same architecture, the original cat is replaced by atoms. The whole system seems to be in harmony with Lena's original hypothesis. It is through this replacement that the mages suddenly wake up.

The problem of this thought experiment is that it uses the method of transmitting the experimental results to demonstrate. If it is true, then it can be extended to the whole universe, and such a demonstration method is obviously impossible in the experiment.The simple explanation is whether the atom decays or not is the reason, while the cat's life and death is the result. Whether the cat decays or not follows the quantum theory, and then we get a result, which determines the cat's life and death. The collapse of wave function actually exists in the microscopic system composed of decaying atoms, which has nothing to do with the cat in the macroscopic system.

If such an experiment really happens in reality, the life and death of the cat can't be determined before opening the box. Even a wave function can be used to describe the life and death of the cat, but the life and death of the cat will not change because of observation, which is in line with the objective law and the principle of not taking human will as the transfer.

"I still have a problem. According to the quantum hypothesis, even the existence of an objective and real object is determined by probability, but simply because its scale is too large to be affected by collapse, coupled with the Ian gray uncertainty principle, our measurement of particles can only be described by probability, but I don't think the world should be so random "It's just a random thing."

Mr. Calvados said that her eyes were on the laws of the whole world. The astrological field she studied did not allow such a probability to determine the existence of material thoughts.

"Lena, the world doesn't roll dice."

When he heard what the other person said, Lena said with a smile.

"Don't tell the world what to do, Monsieur Calvados."
