About Schrödinger's cat in simple words. Schrödinger's theory in simple words

Despite the fact that the planetary model of the atom has proved its worth, the theory existing at that time could not fully explain all the processes observed in real life. It turned out that in reality, for some reason, classical Newtonian mechanics does not work at the micro level. Those. the prototype of the model, borrowed from real life, does not correspond to the observations of scientists of that time in the case of considering an atom instead of our solar system.

Based on this, the concept has been significantly revised. There is a discipline like quantum mechanics. The outstanding physicist Erwin Schrödinger stood at the origins of this trend.

The concept of superposition

The main principle that distinguishes the new theory is superposition principle. According to this principle, a quantum (electron, photon or proton) can be in two states at the same time. If a make it easier to understand this formulation, then we get a fact that is completely impossible to imagine in our minds. A quantum can be in two places at the same time.

At the time of its appearance, this theory contradicted not only classical mechanics, but also common sense. Even now, an educated person, far from physics, can hardly imagine such a situation. After all, this understanding, in the end, implies that he himself the reader can be now and here and there. This is how a person tries to imagine the transition from the macrocosm to the microcosm.

It was extremely difficult for a person who was used to experiencing the action of Newtonian mechanics and perceiving himself at one point in space to imagine being in two places at once. Besides, as such, there was no theory and patterns in the transition from macro to micro. There was no understanding of specific numerical values ​​and rules.

However, devices of that time already made it possible to clearly fix this "quantum dissonance". Laboratory devices have confirmed that the formulated postulates are indeed consistent and the quantum is capable of being in two states. For example, an electron gas was recorded around the nucleus of an atom.

Based on this, Schrödinger formulated the famous concept that is now known as the cat theory.. The purpose of this formulation was to show that there was a huge gap in the classical theory of physics, requiring further study.

Shroedinger `s cat

The thought experiment about the cat was that the cat was placed in a closed steel box. The box was equipped device with poisonous gas and a device with the nucleus of an atom.

Based on well-known postulates, the nucleus of an atom may disintegrate into components within one hour, but may not disintegrate. Accordingly, the probability of this event is 50%.

If the core disintegrates, then the counter-registrar is activated, and in response to this event, the poisonous substance is released from the previously described device with which the box is equipped. Those. the cat dies from the poison. If this does not happen, the cat does not die, respectively. Based on a 50% chance of decay, there is a 50% chance that the cat survives.

Based on quantum theory, An atom can be in two states at once. Those. the atom both decayed and did not decay. This means that the registrar worked, breaking the container with poison, and did not disintegrate. The cat was poisoned by poison, and the cat was not poisoned by poison at the same time.

But to imagine such a picture that opening the box, the researcher immediately found a dead and a living cat is simply impossible. The cat is either alive or dead. This is the paradox of the situation. It is impossible for the viewer's mind to imagine a dead-alive cat.

The paradox is that the cat is an object of the macrocosm. Accordingly, to say about him that he is alive and dead, i.e. is in two states at once, similar to a quantum, will not be entirely correct.

Using this example, Schrödinger concentrated precisely on the fact that there are no clear parallels between the macro- and microworlds.. The subsequent comments given by the experts make it clear that the radiation detector-cat system should be considered, not the cat-viewer. Only one event is probable in the detector-cat system.

There was a kind of "secondary". He himself rarely dealt with a specific scientific problem. His favorite genre of work was a response to someone's scientific research, development of this work or its criticism. Despite the fact that Schrödinger himself was an individualist by nature, he always needed someone else's thought, support for further work. Despite this peculiar approach, Schrödinger managed to make many discoveries.

Biographical information

Schrödinger's theory is now known not only to students of physics and mathematics departments. It will be of interest to anyone who is interested in popular science. This theory was created by the famous physicist E. Schrodinger, who went down in history as one of the creators of quantum mechanics. The scientist was born on August 12, 1887 in the family of the owner of an oilcloth factory. The future scientist, who became famous all over the world for his mystery, was fond of botany and drawing as a child. His first mentor was his father. In 1906, Schrödinger began his studies at the University of Vienna, during which he began to admire physics. When the First World War came, the scientist went to serve as an artilleryman. In his free time, he studied the theories of Albert Einstein.

By the beginning of 1927, a dramatic situation had developed in science. E. Schrödinger believed that the idea of ​​the continuity of waves should serve as the basis for the theory of quantum processes. Heisenberg, on the contrary, believed that the concept of the discreteness of waves, as well as the idea of ​​quantum jumps, should be the foundation for this area of ​​​​knowledge. Niels Bohr did not accept any of the positions.

Advances in Science

For the concept of wave mechanics in 1933, Schrödinger received the Nobel Prize. However, having been brought up in the traditions of classical physics, the scientist could not think in other categories and did not consider quantum mechanics to be a full-fledged branch of knowledge. He could not be satisfied with the dual behavior of particles, and he tried to reduce it exclusively to the wave behavior. In his discussion with N. Bohr, Schrödinger put it this way: "If we plan to keep these quantum leaps in science, then I generally regret that I connected my life with atomic physics."

Further work of the researcher

At the same time, Schrödinger was not only one of the founders of modern quantum mechanics. It was he who introduced the term "objectivity of description" into scientific use. This is the ability of scientific theories to describe reality without the participation of an observer. His further research was devoted to the theory of relativity, thermodynamic processes, Born's nonlinear electrodynamics. Also, scientists have made several attempts to create a unified field theory. In addition, E. Schrödinger spoke six languages.

The most famous riddle

Schrödinger's theory, in which the same cat appears, grew out of the scientist's criticism of quantum theory. One of its main postulates is that as long as the system is not observed, it is in a state of superposition. Namely, in two or more states that exclude the existence of each other. The state of superposition in science has the following definition: it is the ability of a quantum, which can also be an electron, a photon, or, for example, the nucleus of an atom, to be simultaneously in two states or even at two points in space at a time when no one is watching it.

Objects in different worlds

It is very difficult for an ordinary person to understand such a definition. After all, each object of the material world can be either at one point in space or at another. This phenomenon can be illustrated as follows. The observer takes two boxes and puts a tennis ball in one of them. It will be clear that it is in one box and not in the other. But if we put an electron in one of the containers, then the following statement will be true: this particle is simultaneously in two boxes, no matter how paradoxical it may seem. In the same way, an electron in an atom is not located at a strictly defined point at one time or another. It rotates around the nucleus, being located at all points of the orbit at the same time. In science, this phenomenon is called "electron cloud".

What did the scientist want to prove?

Thus, the behavior of small and large objects is implemented according to completely different rules. In the quantum world, there are some laws, and in the macrocosm - completely different. However, there is no such concept that would explain the transition from the world of material objects, familiar to people, to the microworld. Schrödinger's theory was created in order to demonstrate the insufficiency of research in the field of physics. The scientist wanted to show that there is a science whose purpose is to describe small objects, and there is a field of knowledge that studies ordinary objects. Largely due to the work of the scientist, physics was divided into two areas: quantum and classical.

Schrödinger's theory: description

The scientist described his famous thought experiment in 1935. In its implementation, Schrödinger relied on the principle of superposition. Schrödinger emphasized that as long as we do not observe the photon, it can be either a particle or a wave; both red and green; both round and square. This uncertainty principle, which directly follows from the concept of quantum dualism, was used by Schrödinger in his famous cat riddle. The meaning of the experiment in brief is as follows:

• A cat is placed in a closed box, as well as a container containing hydrocyanic acid and a radioactive substance.
• The nucleus can disintegrate within an hour. The probability of this is 50%.
• If the atomic nucleus decays, then this will be recorded by the Geiger counter. The mechanism will work and the poison box will be broken. The cat will die.
• If the decay does not occur, then Schrödinger's cat will be alive.

According to this theory, until the cat is observed, it is simultaneously in two states (dead and alive), just like the nucleus of an atom (decayed or not decayed). Of course, this is possible only according to the laws of the quantum world. In the macrocosm, a cat cannot be both alive and dead at the same time.

Observer paradox

To understand the essence of Schrödinger's theory, it is also necessary to have an understanding of the paradox of the observer. Its meaning is that the objects of the microcosm can be simultaneously in two states only when they are not observed. For example, the so-called "Experiment with 2 slits and an observer" is known in science. On an opaque plate in which two vertical slits were made, scientists directed a beam of electrons. On the screen behind the plate, the electrons painted a wave pattern. In other words, they left black and white stripes. When the researchers wanted to observe how the electrons fly through the slits, the particles displayed only two vertical stripes on the screen. They behaved like particles, not like waves.

Copenhagen explanation

The modern explanation of Schrödinger's theory is called the Copenhagen one. Based on the paradox of the observer, it sounds like this: as long as no one observes the nucleus of an atom in the system, it is simultaneously in two states - decayed and undecayed. However, the statement that the cat is alive and dead at the same time is extremely erroneous. After all, the same phenomena are never observed in the macrocosm as in the microcosm.

Therefore, we are not talking about the “cat-core” system, but about the fact that the Geiger counter and the nucleus of the atom are interconnected. The kernel can choose one or another state at the moment when the measurements are made. However, this choice does not take place at the moment when the experimenter opens the box with Schrödinger's cat. In fact, the opening of the box takes place in the macrocosm. In other words, in a system that is very far from the atomic world. Therefore, the nucleus selects its state exactly at the moment when it hits the detector of the Geiger counter. Thus, Erwin Schrödinger, in his thought experiment, did not fully describe the system.

General conclusions

Thus, it is not entirely correct to associate the macrosystem with the microscopic world. In the macrocosm, quantum laws lose their force. The nucleus of an atom can be simultaneously in two states only in the microcosm. The same cannot be said about the cat, since it is an object of the macrocosm. Therefore, only at first glance it seems that the cat passes from the superposition to one of the states at the moment of opening the box. In fact, its fate is determined at the moment when the atomic nucleus interacts with the detector. The conclusion can be drawn as follows: the state of the system in Erwin Schrödinger's riddle has nothing to do with a person. It does not depend on the experimenter, but on the detector - an object that "observes" the nucleus.

Continuation of the concept

Schrödinger's theory is described in simple terms as follows: while the observer does not look at the system, it can be in two states simultaneously. However, another scientist - Eugene Wigner, went further and decided to bring the concept of Schrödinger to complete absurdity. “Excuse me!” said Wigner, “what if next to the experimenter watching the cat is his colleague?” The partner does not know what exactly the experimenter himself saw at the moment when he opened the box with the cat. Schrödinger's cat leaves the state of superposition. However, not for a fellow observer. Only at that moment, when the fate of the cat becomes known to the latter, can the animal be finally called alive or dead. In addition, there are billions of people on planet Earth. And the final verdict can be made only when the result of the experiment becomes the property of all living beings. Of course, all people can be told the fate of the cat and Schrödinger's theory briefly, but this is a very long and laborious process.

The principles of quantum dualism in physics were never refuted by Schrödinger's thought experiment. In a sense, every creature can be called neither alive nor dead (being in superposition) as long as there is at least one person who is not watching him.

If the box is opened, then the experimenter must see only one specific state: "the nucleus has decayed, the cat is dead", or "the nucleus has not decayed, the cat is alive"

"Schrödinger's cat" is the name of an entertaining thought experiment set up by, you guessed it, Schrödinger, or more precisely, the Nobel laureate in physics, the Austrian scientist Erwin Rudolf Josef Alexander Schrödinger.

Wikipedia defines the experiment as follows: "A cat is placed in a closed box. The box contains a mechanism containing a radioactive nucleus and a container with poisonous gas. The parameters of the experiment are chosen so that the probability that the nucleus will decay in 1 hour is 50%. If the core disintegrates, it sets the mechanism in motion - a container with gas opens, and the cat dies.

According to quantum mechanics, if no observation is made over the nucleus, then its state is described by a superposition (mixing) of two states - a decayed nucleus and an undecayed nucleus, therefore, the cat sitting in the box is both alive and dead at the same time. If the box is opened, then the experimenter must see only one specific state: "the nucleus has decayed, the cat is dead", or "the nucleus has not decayed, the cat is alive."

It turns out that at the output we have a live or dead cat, but in potential, the cat is both alive and dead at the same time. Thus, Schrodinger tried to prove the limitations of quantum mechanics, without applying certain rules to it.

The Copenhagen interpretation of quantum physics - and in particular this experiment - indicates that the cat acquires the properties of one of the potential phases (alive or dead) only after the observer interferes with the process.

That is, when a particular Schrödinger opens the box, he will have to cut sausages with one hundred percent certainty or call the veterinarian. The cat will definitely be alive or suddenly dead. But as long as there is no observer in the process - a specific person who has undoubted merits in the form of vision, and at least a clear consciousness - the cat will be in a suspended state "between heaven and earth."

The ancient parable about a cat that walks by itself takes on new shades in this context. Undoubtedly, Schrödinger's cat is not the most prosperous creature in the universe. Let's wish the cat a successful outcome for him and turn to another entertaining problem from the mysterious and sometimes merciless world of quantum mechanics.

It sounds like this: "What sound does a tree falling in the forest make if there is no person nearby who can perceive this sound?" Here, in contrast to the black and white fate of the unfortunate / happy cat, we are faced with a multi-colored palette of speculations: there is no sound / there is a sound, what is it, if it is, and if it is not, then why? It is impossible to answer this question for a very simple reason - the impossibility of carrying out the experiment. After all, any experiment implies the presence of an observer who is able to perceive and draw conclusions.

That is, it is impossible to assume what happens to the objects of the reality around us in our absence. And if it cannot be perceived, then it does not exist. As soon as we leave the room, all its contents, together with the room itself, cease to exist or, more precisely, continue to exist only in potential.

At the same time, there is a fire or flood, equipment theft or intruders. Moreover, we also exist in it, in different potential states. One I walks around the room and whistles a stupid melody, the other I looks sadly at the window, the third one talks to his wife on the phone. Even our sudden death or joyful news in the form of an unexpected phone call lives in it.

Imagine for a moment all the possibilities hidden behind the door. Now imagine that our entire world is just a collection of such unrealized potentials. Funny, right?

O However, a natural question arises here: so what? Yes - funny, yes - interesting, but what, in fact, does it change? Science is modestly silent about this. For quantum physics, such knowledge opens up new ways in understanding the Universe and its mechanisms, but for us, people far from great scientific discoveries, such information seems to be useless.

How is that for nothing!? After all, if I, a mortal, exist in this world, then I, an immortal, exist in another world! If my life consists of a streak of failures and sorrows, then somewhere I exist - lucky and happy? In fact, there is nothing outside our sensations, just as there is no room until we enter it. Our organs of perception only deceive us, drawing in the brain a picture of the world "surrounding" us. What is actually outside of us remains a mystery behind seven seals.

We have all heard about the famous Schrödinger's cat, but do we know what kind of cat it really is? Let's figure it out and try to talk about the famous Schrödinger's cat in simple words.

Schrödinger's cat is an experiment conducted by Erwin Schrödinger, one of the founding fathers of quantum mechanics. Moreover, this is not an ordinary physical experiment, but mental.

It must be admitted that Erwin Schrödinger was a very imaginative man.

So, what do we have as an imaginary basis for the experiment? There is a cat placed in a box. The box also contains a Geiger counter with some very small amounts of radioactive material. The amount of substance is such that the probability of decay and non-decay of one atom within an hour is the same. If the atom decays, a special mechanism will start that will break the flask with hydrocyanic acid, and the poor cat will die. If the collapse does not occur, then the cat will continue to sit quietly in his box and dream of sausages.

What is the essence of Schrödinger's cat? Why even come up with such a surreal experience?

According to the results of the experiment, we will know whether the cat is alive or not only when we open the box. From the point of view of quantum mechanics, a cat simultaneously (like an atom of matter) is in two states at once - both alive and dead at the same time. This is the famous paradox of Schrödinger's cat.

Naturally, this cannot be. Erwin Schrödinger set up this thought experiment to show the imperfection of quantum mechanics when moving from subatomic to macroscopic systems.

Here is Schrödinger's own formulation:

You can also construct cases in which burlesque is enough. Let some cat be locked in a steel chamber along with the following diabolical machine (which should be independent of the intervention of the cat): inside the Geiger counter is a tiny amount of radioactive material - so small that only one atom can decay in an hour, but with the same the probability may not fall apart; if this happens, the reading tube is discharged and a relay is activated, lowering the hammer, which breaks the cone of hydrocyanic acid.

If we leave this whole system to itself for an hour, then we can say that the cat will be alive after this time, as long as the atom does not decay. The first decay of an atom would have poisoned the cat. The psi-function of the system as a whole will express this by mixing in itself or smearing the living and dead cat (forgive the expression) in equal proportions. Typical in such cases is that the uncertainty, originally limited to the atomic world, is transformed into a macroscopic uncertainty that can be eliminated by direct observation. This prevents us from naively accepting the "blur model" as reflecting reality. By itself, this does not mean anything unclear or contradictory. There is a difference between a fuzzy or out of focus photo and a cloud or fog shot.

A definitely positive point in this experiment is the fact that not a single animal was harmed during its course.

Finally, to consolidate the material, we suggest you watch a video from the good old series "The Big Bang Theory".

This is a cat that is both alive and dead at the same time. He owes such an unfavorable state to the Nobel laureate in physics, the Austrian scientist Erwin Rudolf Joseph Alexander Schrödinger.

The essence of the experiment / paradox

The cat is in a closed box, where there is a mechanism containing a radioactive core and a container with poisonous gas. The characteristics of the experiment are chosen so that the probability that the nucleus will disintegrate in 1 hour is 50%. If the core disintegrates, it sets the mechanism in motion, the gas container opens, and the cat dies. According to quantum mechanics, if no observation is made over the nucleus, then its state is described by a superposition (mixing) of two states - a decayed nucleus and an undecayed nucleus, therefore, the cat sitting in the box is both alive and dead at the same time.

It is worth opening the box - and the experimenter should see only one state - "the nucleus has decayed, the cat is dead" or "the nucleus has not decayed, the cat is alive." But while there is no observer in the process, the ill-fated little animal remains "dead".

Marginals

• Misfortune never comes alone
  Not only the health of the tailed inhabitant of the box is in doubt, but also its gender: in the original experiment, Schrödinger's cat was still a cat (die Katze).
• There are no "dead" cats
  It is important to remember that Schrödinger's experiment is not intended to prove the existence of "dead" cats (and, contrary to what was said in the second part of the Portal game, was not invented as an excuse for killing cats). Obviously, the cat must necessarily be either alive or dead, since there is no intermediate state.
  Experience shows that quantum mechanics is not able to describe the behavior of macrosystems (which the cat belongs to): it is incomplete without some rules that indicate when the system chooses one particular state, under what conditions the wave function collapses and the cat either remains alive or becomes dead. , but ceases to be a mixture of both.

Interpretations Copenhagen interpretation denies that before opening the box, the cat is in a state of mixing of the living and the dead. Some believe that as long as the box is closed, the system is in a superposition of the states “decayed nucleus, dead cat” and “undecayed nucleus, living cat”, and when the box is opened, only then does the wave function collapse to one of the options. Others - that "observation" occurs when a particle from the nucleus enters the detector; however, alas, in the Copenhagen interpretation there is no clear rule that says when this happens, and therefore this interpretation is incomplete until such a rule is introduced into it or it is not said how it can be introduced in principle. Everett's Many Worlds Interpretation, unlike Copenhagen, does not consider the process of observation to be something special. Here both states of the cat exist, but decohere - that is, as the author understood, the unity of these states is broken as a result of interaction with the environment. When the observer opens the box, he becomes entangled (mixed) with the cat, which results in two states of the observer, one corresponding to a live and one to a dead cat. These states do not interact with each other. The cat as a competent observer
The author believes that the decisive word should have been left to the cat, who, although not understanding a single belmes in quantum mechanics, is certainly the best aware of his condition. However, his competence as an observer, obviously, raises doubts among scientists. The exceptions are Hans Moravec, Bruno Marshal and Max Tegmark, who proposed a modification of the Schrödinger experiment, known as "quantum suicide", which is an experiment with a cat from the point of view of a cat. Scientists pursued the goal of showing the difference between the Copenhagen and many-worlds interpretations of quantum mechanics. If the multi-world interpretation is correct, the cat, to the delight of the sympathizers, becomes Tsoi and always remains alive, since the participant is able to observe the result of the experiment only in the world in which he survives.

• Nadav Katz of the University of California and his colleagues published the results of a laboratory experiment in which they managed to "return" the quantum state of a particle back, and after measuring this state. Thus, it is possible to save the life of a cat, regardless of the conditions for the collapse of the wave function. It doesn't matter if he is alive or dead: you can always win back [link] .
• 06/03/2011 RIA Novosti reported that Chinese physicists were able to create eight-photon "Schrodinger's cat"[link] which should contribute to the development of future quantum computers

Image in culture

Perhaps no one has done more to popularize quantum mechanics than the poor cat. Even the people who are farthest from this complex field of knowledge, excited by the fate of the probably suffering little animal, are trying to figure out the intricacies of the experiment, hoping that not everything is so bad. The cat inspires artists and popular culture.
Let us mention his main merits:

Literature: The situation with Schrödinger's cat is discussed by the protagonists of Douglas Adams' book Dirk Gently's Detective Agency. In Dan Simmons' book Endymion, the protagonist Raoul Endymion writes his narrative while orbiting Armagast in Schrödinger's "cat box". In the last third of Robert Heinlein's book The Cat Who Passes Through Walls, the ginger cat Pixel appears, which has the property of a Schrödinger cat to be in two states at the same time. In Terry Pratchett's book "Cat Without Fools", a breed of so-called "Schrödinger cats" is described in a humorous form, descended from the same Schrödinger's cat. Also, this thought experiment is mentioned more than once in other works of Pratchett, for example, in the novel Ladies and Gentlemen. In F. Gwinplein McIntyre's story "Nursing Schrödinger's Cat", one of the characters is Schrödinger's own pet, Tibbles the cat. Around this cat, in fact, the action of a humorous story unfolds, generously seasoned with details from different areas of physics. The plot of Frederick Pohl's science fiction novel The Coming of the Quantum Cats (1986) is based on the idea of ​​the interaction of "neighboring" Universes. In Nikolai Baytov's philosophical and satirical miniature "Schrödinger's Cat", Schrödinger's paradox is turned inside out: an organization called the "League of Reversible Time" has been conducting uninterrupted observation of a live cat in a box for 50 years, believing that while observation is being carried out - a state , in which the cat resides, should not change. In Lukyanenko's book "The Last Watch", the main character is thrown around the neck with a noose called "Schrödinger's cat", the peculiarity of which is that magicians do not understand whether this creature is alive or not. Mentioned in Greg Egan's novel "Quarantine", in Christopher Stashef's fantasy "Mage Healer", by Greg Beer (Gregory Dale Bear) in the story "Schrödinger's Plague"; Polish writer Sapkowski mentions Kodringer's cat. Mercy Shelley's cyberpunk novel 2048 states that "a guy with a file-like last name was putting some unfortunate biorg in an iron box containing nothing but a vial of poison." Svetlana Shirankova's poem "Schrödinger's Cat" has a very inspiring beginning: "Doctor Schrödinger, your cat is still alive." Screen: In the Coen brothers' film A Serious Man, a student says to a professor, "I understand the dead cat experiment," which, of course, suggests otherwise. In the film "Repo Man" ("Collectors", in the Russian box office "Rippers"), the main character at the beginning of the film talks about an unknown scientist who has a cat. And this cat is in the state of "... both alive and dead at the same time ...". In one of the episodes of the science fiction series Stargate SG-1, a cat named Schrödinger appears. The protagonist of the sci-fi series Sliders also has the same name cat. In Stargate SG-1, a ginger cat named Schrödinger was given to an alien. Dead cat Schrödinger appears in CSI: Las Vegas (Season 8, Episode 15: The Theory of Everything). Schrödinger's cat is also mentioned in the TV series The Big Bang Theory, where as an answer to a girl's question whether she should go on a date, the hero draws an analogy with Schrödinger's cat, meaning that until you try, you won't know: "Penny, for in order to find out whether the cat is alive or dead, you need to open the box. In the series "Bugs", the role of Schrödinger's cat was played by the Red Mercury clue in a booby-trapped safe. In the Japanese anime "Hellsing (OVA)" (as well as in the manga of the same name), there is a cat-man character named Schrödinger, who is neither alive nor dead, has the ability to teleport ("be everywhere and nowhere"), and is absolutely unkillable. In the anime "To Aru Majutsu no Index", the protagonist objects to the girl's proposal to name the kitten Schrödinger that cats cannot be called this name. The anime Shigofumi also features a cat named Schrödinger. In the Japanese anime and game Umineko no naku koro ni, experience is used in Battler's attempt to prove the impossibility of magic (also used are Devil's Proof, Hempel's Crows, Laplace's Demon). In one of the Futurama episodes Law and Oracle, Schrödinger hid drugs in a box with a cat. Comics/manga: A small comic book about Schrödinger's cat and Maxwell's demon. He's Dead: Schrödinger of the Cat: And More Comics at joyreactor.ru. Games: There is a quest game "The Return of the Quantum Cat". In the Nethack game, there is a Quantum Mechanic monster, which sometimes has a box with a cat with it. The state of the cat is not determined until the moment the box is opened. In the game "Half-Life 2" there was a cat in the laboratory with teleporters, nightmares about which "still" visit Barney. The portrait of Schrödinger's cat is also found in the 1998 remake based on Half-Life. - "Black Mesa" ("Black Mesa", formerly known as "Black Mesa: Source"). Link to notarized screenshot. In every level of Bioshock, there is a dead cat in a nook, labeled Shrodinger. In the second part, it can also be found - the cat rests in one of the ice floes in a frozen room with four surveillance cameras in the corners. The NPC cat of the same name is featured in the Japanese RPG Shin Megami Tensei: Digital Devil Saga. The main slogan of the game Portal, "The cake is a lie", is an errative of one of the outcomes of the Schrödinger experiment, namely "The cat is alive". In the second part of the game, the cat is also not forgotten. A mention of the experiment can be found in the rule book of the Russian board game Age of Aquarius. The cat even has its own characteristic plate there - it is completely empty, so it seems that it is not there. Music: The so-called festival of non-standard music "Schrödinger's Cat", which took place under the slogan "Real life - real death - real music!" and “Is Schrödinger's Cat alive or dead? And you?" Google also reports that the name "Schrödinger's Cat" is a near-musical project of a very small team from Korolev near Moscow. The album of the British band Tears for Fears "Saturnine Martial and Lunatic" contains a song of the same name. The Russian band "Allein Fur" Immer also performs a song with the same name. Humor: Any joke about Schrödinger's cat is funny and unfunny at the same time. Schrödinger and Heisenberg drive down the highway to the conference, Schrödinger driving. Suddenly there is a blow and he stops the car. Heisenberg looks down the road:
- My God, it looks like I hit a cat!
- He died?
- I can not say exactly. Schrödinger walked around the room in search of a kitten that had shit, and he was sitting in a box, neither alive nor dead. Miscellaneous: Artists pay attention to Schrödinger's cat, trying to convey the ambiguity of his position by means of painting and graphics. Also, images of this little animal can be seen on T-shirts and mugs. Terrorists of whom it is not known exactly whether they are alive or dead are sometimes referred to as "Schrödinger terrorists". Of the well-known personalities, for example, Yasser Arafat was in this state when he was in a coma before his death, as well as Osama bin Laden. According to Absurdopedia, the cat in the poke is a simplified version of the Schrödinger's cat experiment [link] . Stephen Hawking paraphrased Hans Jost's catchphrase "When I hear about culture, I grab my gun" as follows: "When I hear about Schrödinger's cat, my hand reaches for a gun!" The explanation is that, like many other physicists, Hawking is of the opinion that the "Copenhagen School" of the interpretation of quantum mechanics emphasizes the role of the observer unreasonably. In connection with the opening of the MEPhI Department of Theology, the following picture has become widespread on the network:
