I tried to make a joke to a group of scientifically literate friends. I brought up the subject of Schrodinger cat. Then I said, "Being sealed in a box with a tin of poison is not a superposition to be in." Nobody got it.
Your friends are also in a state of superposition as they may or may not understand, because they may or may not be quantum literate, or even if they do, they may or may not care, therefore they may or may not laugh.
Well, you raise an interesting possibility but it was more the opposite. This group was mostly PhDs. They were so hyper focused on actually understanding the theoretical idea behind "Shrodinger's Cat", they missed the joke entirely. It's like I invented a cloaking device. BTW, what is a coat rack... but a cloaking device? LOL Why they let me hang around I don't know. @@HighMojo
It's safer for them not to laugh whether they understood the joke or not. A moan and a small smile would have been nice to at least acknowledge that you had attempted a joke.
Appreciate the detailed breakdown! Could you help me with something unrelated: I have a SafePal wallet with USDT, and I have the seed phrase. (air carpet target dish off jeans toilet sweet piano spoil fruit essay). Could you explain how to move them to Binance?
QM classicalized in 2010. Forgotten Physics website uncovers the hidden variables and constants and the bad math of Wien, Schrodinger, Heisenberg, Einstein, Debroglie,Planck, Bohr etc. So,no.
You’re incorrect about Shrodengers (spelling) cat. He came up with that thought experiment to show how absurd it is to state that the cat is both dead and alive. That’s not how the world works. A cat in a box is either alive or dead. Period. We don’t fully understand the math or the correct way to measure the quantum realm so we can’t describe everything about it.
Yes, we do understand both the math and the physics of this fully. It was Schroedinger who didn't. He wrote an article that was full of confusion and he ruined the subject with his explanation for generations of people who are being deceived by his false reasoning.
So as I understood it, (and I literally just watched it myself so I have no idea if I’m right) if a particle can exist in 2 different distinct stages, it would lend credence to the theory that both states of this particle are their own seperate interpetation of reality. We know where the particle should be in a place but at the same time it can be a different place and should be a different place from another alternate reality. Only thing I’m certain of is that it is merely a theory at this stage. Maybe this can simplify it: Imagine a quantum car. Since quantum physiqs the car exists both in the parking lot basement and the top floor at the same time, yet you can only see and predict the car to be in the parking lot, therefore an alternate reality of you would see the car on the rooftop. (Anyone smarter than me please correct me if I missed the mark completely!!! 😅)
Particles don't have different locations. More precisely, particles do not even exist for all we know. Nobody has ever seen one. What we are observing are exchanges of quanta of energy between physical systems, but because "shut up and calculate" works for most users science is not self correcting with regards to teaching the wrong ontology. Most physicists never notice that they have been taught wrong and so they continue teaching wrongly.
Mass is occupied areas of space. Cold space is in mass. Mass is in constant maximum velocity momentum propelled through space. Cold resistance is transferring through mass, as mass momentum is in constant forward momentum in resistance. Magnetic fields are created by resistance to forward momentum causing mass to cycle in on itself. The greater the mass the greater resistance to forward momentum. Resistance in mass is in equalization as outward force contained in magnetic fields of forced cycling circulation patterns. Distance is reduced as mass expansion increases resistances to forward momentum. Momentum is constant velocity in entanglement and out of entanglement. Maximum momentum velocity of thermal energy singularity frequencies is a constant value. Frequency is vibrating from avoidance patterns of spiraling through cold resistance that is the fabric of space that is transferring through mass in transitioning areas of occupation time-line. Equalization is maintained in cycling circulation of outward pressure held in magnetic fields of forced flow. Frequencies spiraling rebounding in contained fields of force holding mass together in cycles of maximum momentum velocity of thermal energy singularity frequencies amassed in entanglement.
Does not make any sense. Could you explain in simple english rather than make it so complicated for a layman to understand? The simpler you xan make the bigger expertise you have in the subject rather than going all technical mumbo jumbo.
I dont understand why everyone always misrepesents the shroedingers cat thing. What about the world from the cats point of view? like it or not the cats point of view is there and it doens entangle with the subatomic realm just like us.
The cat doesn't matter. The point of Schroedinger's cat is to show that there is a non-trivial difference between reversible and irreversible systems. Quantum mechanics expresses that gap perfectly fine, Schroedinger was simply not happy that the gap exists in the first place and it ain't small. It's actually what creates reality.
It saddens me that people will see all these silly movies, and talk like they understand the quantum universe. People see movies and cartoons, and think they are smart. I've been srudying quanrum physics for a few years now... and it still amazes me! We have no idea of how it works.... but we know it does.
"“If you think you understand quantum mechanics, you don't understand quantum mechanics.” So i'm in a superposition of both knowing and not knowing Quantum Mechanics?
Wow... you are the first person I have seen online who actually noticed that Feynman made a (poor) joke about superposition there! Congrats. You have a sense of humor. :-)

Hi science ABC. Could you do a video on Loop quantum gravity. Other youtubers explain in a very complicated way, but maybe your explanation might be better
I really need this level of explanation of Quantum Physics. Much more and I glaze over. But isn't it the most mind-blowing thought that Gautama Buddha, alive 500 years before Christ, perfectly understood that there is no permanent 'me' or anything else. And observed it without any equipment or experiments.
Schrödinger's thought experiment wasn't meant to explain quantum superposition. It was meant as a criticism of the Copenhagen interpretation of Quantum Mechanics. A cat being both alive and dead at the same time is bogus, right? Well, yeah, that's what Schrödinger was getting at. He was basically saying that the Copenhagen interpretation leads to absurd conclusions when applied to everyday objects.
Quantum mechanics is a fundamental theory in physics that describes the behavior of nature at and below the scale of atoms.[2]: 1.1 It is the foundation of all quantum physics, which includes quantum chemistry, quantum field theory, quantum technology, and quantum information science. Quantum mechanics can describe many systems that classical physics cannot. Classical physics can describe many aspects of nature at an ordinary (macroscopic and (optical) microscopic) scale, but is not sufficient for describing them at very small submicroscopic (atomic and subatomic) scales. Most theories in classical physics can be derived from quantum mechanics as an approximation valid at large (macroscopic/microscopic) scale.[3] Quantum systems have bound states that are quantized to discrete values of energy, momentum, angular momentum, and other quantities, in contrast to classical systems where these quantities can be measured continuously. Measurements of quantum systems show characteristics of both particles and waves (wave-particle duality), and there are limits to how accurately the value of a physical quantity can be predicted prior to its measurement, given a complete set of initial conditions (the uncertainty principle). Quantum mechanics arose gradually from theories to explain observations that could not be reconciled with classical physics, such as Max Planck's solution in 1900 to the black-body radiation problem, and the correspondence between energy and frequency in Albert Einstein's 1905 paper, which explained the photoelectric effect. These early attempts to understand microscopic phenomena, now known as the "old quantum theory", led to the full development of quantum mechanics in the mid-1920s by Niels Bohr, Erwin Schrödinger, Werner Heisenberg, Max Born, Paul Dirac and others. The modern theory is formulated in various specially developed mathematical formalisms. In one of them, a mathematical entity called the wave function provides information, in the form of probability amplitudes, about what measurements of a particle's energy, momentum, and other physical properties may yield. Overview and fundamental concepts Quantum mechanics allows the calculation of properties and behaviour of physical systems. It is typically applied to microscopic systems: molecules, atoms and sub-atomic particles. It has been demonstrated to hold for complex molecules with thousands of atoms,[4] but its application to human beings raises philosophical problems, such as Wigner's friend, and its application to the universe as a whole remains speculative.[5] Predictions of quantum mechanics have been verified experimentally to an extremely high degree of accuracy. For example, the refinement of quantum mechanics for the interaction of light and matter, known as quantum electrodynamics (QED), has been shown to agree with experiment to within 1 part in 1012 when predicting the magnetic properties of an electron.[6] A fundamental feature of the theory is that it usually cannot predict with certainty what will happen, but only give probabilities. Mathematically, a probability is found by taking the square of the absolute value of a complex number, known as a probability amplitude. This is known as the Born rule, named after physicist Max Born. For example, a quantum particle like an electron can be described by a wave function, which associates to each point in space a probability amplitude. Applying the Born rule to these amplitudes gives a probability density function for the position that the electron will be found to have when an experiment is performed to measure it. This is the best the theory can do; it cannot say for certain where the electron will be found. The Schrödinger equation relates the collection of probability amplitudes that pertain to one moment of time to the collection of probability amplitudes that pertain to another.[7]: 67-87 One consequence of the mathematical rules of quantum mechanics is a tradeoff in predictability between different measurable quantities. The most famous form of this uncertainty principle says that no matter how a quantum particle is prepared or how carefully experiments upon it are arranged, it is impossible to have a precise prediction for a measurement of its position and also at the same time for a measurement of its momentum.[7]: 427-435 Another consequence of the mathematical rules of quantum mechanics is the phenomenon of quantum interference, which is often illustrated with the double-slit experiment. In the basic version of this experiment, a coherent light source, such as a laser beam, illuminates a plate pierced by two parallel slits, and the light passing through the slits is observed on a screen behind the plate.[8]: 102-111 [2]: 1.1-1.8 The wave nature of light causes the light waves passing through the two slits to interfere, producing bright and dark bands on the screen - a result that would not be expected if light consisted of classical particles.[8] However, the light is always found to be absorbed at the screen at discrete points, as individual particles rather than waves; the interference pattern appears via the varying density of these particle hits on the screen. Furthermore, versions of the experiment that include detectors at the slits find that each detected photon passes through one slit (as would a classical particle), and not through both slits (as would a wave).[8]: 109 [9][10] However, such experiments demonstrate that particles do not form the interference pattern if one detects which slit they pass through. This behavior is known as wave-particle duality. In addition to light, electrons, atoms, and molecules are all found to exhibit the same dual behavior when fired towards a double slit.[2] Another non-classical phenomenon predicted by quantum mechanics is quantum tunnelling: a particle that goes up against a potential barrier can cross it, even if its kinetic energy is smaller than the maximum of the potential.[11] In classical mechanics this particle would be trapped. Quantum tunnelling has several important consequences, enabling radioactive decay, nuclear fusion in stars, and applications such as scanning tunnelling microscopy,tunnel diode and tunnel field-effect transistor.[12][13]
Quark was a short lived sci fi TV show that parodied Trek and Star Wars in the late 1970s starring Richard Benjamin. Also a Ferengi bartender on Deep Space 9. What did you hope to learn?
Quantum physics is the probability of an electron existing in a certain state. Lets say an electron is currently existing in one corner of a room. So, all the probabilities of the electron existing in other corners or possible direction in the future is quantum mechanics (simplified)
Particles are too small to see. So their experiments always involve using many particles, many experiments. Then they use statistics to analyze the data. And then they decided to tell everyone physics is just statistics and averaging without any evidence at all. Their first rule was to never talk about classical physics again. That's why Feynman got a whole lot of heat for his Feynman diagrams--because they didn't involve statistics, they just involved common sense Newtonian type motion. That's the truth in ridiculously easy words.
Lol, so what you're saying is you attempt to teach complicated physical and mathematical concepts, but you don't understand the plot of Avenger's Endgame
It’s a very bad idea of explaining something (voice over) and at the same time what we are seeing is different, and even as different text. It’s ridiculous you guys don’t understand the brain can not capture information this way. Sorry, very bad video. It could have been goo doe since the voice over text is not bad.
Agreed. I know the presenter is trying to make quantum physics intelligible to the layman but this video sounded (and looked) like something Kamilla Harris would have offered up. (Just the cackling was missing).
You were joking right... No harm came to kitty in this interpretation of Schrodinger's law RIGHT... cause if a hypothetical Mr/Mrs MeowmeowkittyPuffpuff comes to harm ...... ..... ....... thems fighten werds...
So basically it’s studying the air? This is way too abstract for me right now. Have they actually confirmed any scientific laws from this or is it all theories and what ifs?
If this is true of matter at a very small scale, why do large objects appear stable from one moment to the next? I assure you my cat is not dead and alive at the same time.
If a tree falls no one’s there does it make a sound??? Of course it does. It’s not not dead or alive in a superposition hahaha 🤣. It’s either dead or alive it’s not a superposition at all. This daft for physics ppl to say it’s equation equations can be solved this is just speculation. Look this cat is either dead or alive because we are physical beings god made is of course it’s alive or dead stop messing around I want real equations
can't help but feeling the whole thing was informative but incredibly condescending. this opinion is not effected by my race gender or any other sensitivity.
