SCHRÖDINGER'S CAT EXPLAINED 

So there's a universe out there that I'm a hardworking successful individual?

schrödinger: Mr Veterinarian, how is my cat doing? doctor: i've got good news and bad news.

There is also an universe where a man is put inside a box and this theroy is called schrodinger`s human

So I said to shrodinger, "Think outside the box!"

I'm gonna be totally honest, I found myself relieved each time the cat was observed, it was still alive.

Seems like Schrodinger was not much of a cat person…

schrödinger: I got you a gift me: *sigh* is it another dead cat? schrödinger: we won’t know until you open it!

Me: How many parallel universes are there? Schrödinger: Yes

The video fails to mention that Schrodinger created this experiment as a means to prove how ridiculous the theory is though...

One of the most clear explanation about the Schrödinger’s cat!! Well done!

This was the video that actually explained this in a way I could understand - finally!! ✨

Since I came across this concept this is the second video I am watching. And I am 100% sure that i dont have watch anymore for better understanding. A good explanation love. Kudos. GOD bless you

So you're saying if no one observes the cat either living or dying it then has a super position? But doesn't the cat observe it all?

Schrodinger did not invent the cat story to show how weird quantum mechanics is, but to show how ridiculous the Copenhagen interpretation, in which the observer plays a critical role, is. He did not believe the cat would be in a superposition of dead and alive, he considered it nonsense and so do I. The later idea that the Universe splits in two at every quantum event that could have two outcomes is even more nonsensical.

Thank you! The logic of Schrodinger's Cat just wasn't clicking for me even after watching 2 other videos I still couldn't quite get it. After watching yours I am pretty sure I got it! You explained it so clearly to someone without any previous study! Thanks a bunch!

In one universe, I wiped my butt... In another, my butt IS the universe.

I loved the video! Mind blown in this universe... In another universe, I did not like the video... but who cares, we aren't there! :P

This implies we are living multiple lives, potentially ad infinitum, in parallel dimensions, without even being aware of one another, yet independently making choices and consistently creating new universes of possibility.

I’ve watched many videos on Schrodinger’s Cat and this one explained it my untrained mind the best. Thank you!

Thanks so much! Super straight forward, well informed and easy to follow. Definitely subscribed, keep up the great work!

Just shake the box!

Flip a coin, I call heads, you call tails. It's tails. But actually it was heads, but because you looked at it and called tails, split into a different timeline, therefore you cheated, it was heads in the original timeline!

I love the way this was explained. I understood this topic even more.

Who is here after watching episode 7 of s3 dark?

Very good explanation

26 cats voted this video down

Surely that means that’s there’s a universe in which someone has figured out how to travel between universes, and decided to come to ours to tell us about it

Great video! However, I am still confused as to why observation collapses multiple superpositions of a particle into one position. I understand how the observer effect can alter the position of particles and waves, but what I don't understand is why it would matter if something is being observed in terms of whether it is in a superposition or in a single position.

There was a man that had a pet cat/dog, so smart, that when he said to the animal: Do you wanna play fetch or not? The cat/dog played fetch or not at the same time.

Could you believe that?! Universe is full of mysteries :D and great explaination tho :)

*So, If the Cat is Dead, then "Your Curiosity" has Killed the Cat.*

the first time someone explained these ideas in a logical way bravo! encore!

In the original experiment (theorized), the Geiger counter tripped a switch that broke a flask of Hydrogen Cyanide which killed the cat - not the tiny amount of radiation.

I really like your videos!! Keep up the good work

Schrodinger cat is just an amazing concept to explain about unique aspect of quantum theory. His wave equation is more complicated.

Anyone here from Dark

Schrödinger's smiley: : ) :

I learned 2 things: 1.i understood this theory 2.that Stan lee did his research veeery well :) Rip Stan lee :(

Best explanation of Schrodinger's cat and its implications I have found.

This was actually a really big help, I was making it harder than it actually was.thank you

Great explanation. In another universe it was absolutely dreadful. Oh well, good thing we aren't there ;)

Anyone will be in love with physics when he truely understands it. If ur not in love, u dont understand it

thank you, you explained this very clearly. this is seriously crazy stuff

So since I'm here in my room with no one observing me am I in a super state? Am I everywhere?

"OH, a world where we're all evil" "Been there-it sucks"

Thanks, London City Girl, that was a fantastic breakdown.

Thank you. Much easier to understand than the TED explanation.

the biggest use of this theory is seen in dark season 3 by seeing that u correct understand it🤗😁😅

Hello from 2020. *I’d say just shake the box*

Actually, what almost everyone seems to have forgotten is that A. 'Schrodinger'S cat' was Schrodinger ironic statement concerning the theory of superposition. B. The point of the whole cat being ' both death and alive' was his way of asking the question 'Where lies the border between quantum reality and Macro reality? He chose the unpredictability of Uranium's decay as the representation of quantum reality. And the cat presenting the macro reality . The cat being 'both death and alive' pointing to the absurdity of superposition.

Way more satisfying than any other videos over this theory

Why can’t you just get a glass box?

just so you know if you try this the cat will probably be dead

Erwin Schrödinger was driving home one night when he was pulled over by the police. The officer asked him to step out of the car while he searched the vehicle. After a while, he went to the back of the car and opened the trunk. In that moment, the officer said, "hey do you know that you've got a dead cat in here?" To which Schrödinger replies, "Well I do now".

thank you for your easy to understand explanation

did anyone else look this up after watching the film "coherence"?

I usually take this as the poorest theory I've ever heard

thank you. haven't been able to find a simple explanation on yt

Brilliant video. I have just subscribed to your channel. Keep up the good work.

Could there be a universe where the cat puts Schrodinger in a box?

in my universe we call this "Cat's Shrodinger", it's about a Shrodinger in a box, meow.

I wasn't looking for an explanation of superposition, but I got it and kinda needed it.

Is "observing" the cat limited to opening the box any physically seeing it or does that include listening to any sounds that might be coming from the box (which would suggest life)?

Put a camera on the box and the Universe will not split. 😊

So I am rich, handsome, and famous in another world. But my states collapsed into reality and it is my observer's fault :D

This is an invitation to see an artist theory on the nature of time as a universal process of energy exchange with an emergent future relative to the atoms of the periodic table.

Finally a video that actually made this make sense

MAN MADE IT TO THE MOON.......LOL TELL THAT TO STANLEY KUBRICK

"There is a world where man never made it to the moon" its like me saying there is a world where the earth is flat. Couple layers of irony here

Best explanation yet. Thanks.

Starting at timestamp~ 0:45 is the state the particle finally chooses to go into after measurement (after superposition collapses) one of the previous states measured at about timestamp 0:38 ?

If you haven't seen dark series on Netflix then watch it and then watch this video again!! You'll be surprise!!

I came here after watching dark

Subscribed! I just watched many other videos on this subject that left me scratching my head. This one help me understand the absurdity that is quantum mechanics. Thank you!

Thank you it helped me a lot .. keep going😊

Who came here after watching DARK? :D

Hit or Miss? I gue- Shut up. It's both now.

My head has never hurt this much

I've watched a few quantum theory videos, such as your video on string theory. One that I'm hung up on is the theory of Schrodinger's Cat , this very theory, and the multiple universe theory that is born of it. If this theory holds true, is there a possible path where the universe might never die out? Is there a chance that there is - in an alternate universe - a species so advanced that it might reach beyond the confines of it's own universe to manipulate others? Would that not have a rebounding effect on itself? What would happen? Is there already a theory derived of these ponderings? Am I over thinking things? Am I just totally lost to the concept here? Seriously, watching these videos have left me awed and confused.

whos here after hearing this from Dark?

Here because of COHERENCE

Great video. Easy to understand.

Particles can only travel at the speed of light, so they cant be everywhere at once. A particle can naturally decay without being measured, but it cannot be in two states at the same time. At any given instant in time, the particle can only be in one definite state, either as a particle or a decay product. The process of decay involves the particle transitioning from one state to another over a certain period of time, during which it cannot be in both states simultaneously. The experiment was only conceptual thought experiment, not to be taken literally.

If you replace the cat with a human, is he still both dead and alive? The human can look for himself, but why can't a cat?

slight problem - the cat is a living entity with consciousness and has its own observations that are fracturing realities and collapsing wave functions (superPositions). So why would the cat care if a human was observing the box? theres a 50/50 chance the human might not make the observation from the cats perspective. what about micro-organisms inside the box? they are generating their own consciousness and effecting reality, They must be considered too. This sounds more like a god analogy. Erwin Schrodinger was very religious and i think this is about a creator. God is watching at all times, if you are good and follow his word you will receive the positive outcome etc. God = energy field.

These videos give me hope that my cat is still alive in another reality . In memory of Charlie who broke my heart the night he died . I love Charlie

Thanks for explaining this in common sense terms

Why would nobody actually do the shcrodinger cat experiment???

ok, first of all, you stated the experiment wrong. the cat is not killed by radiation, the radiation triggers the release of a poison, which in turn kills the cat. furthermore, you completely failed (or actually didnt even try) to resolve the paradox. obviously the cat is NOT dead and alive while the lid is closed and its state is certainly NOT determined the moment you open the lid and that is NOT what this thought experiment is telling us. the very simple explanation for this "mind-boggling" paradox is that "observation" in this context has nothing to do with US (as sentient and intelligent beings) observing it. it simply means that the particle interacts with another particle and thus has to collapse into a certain state (because the outcome of the interaction is dependent on the state of the particles at the time of the interaction). these interactions happen all the time and as soon as a certain outcome is reached, the fate of the cat is sealed, whether we open the lid or not (well, technically we can save the cat by removing it from the poisonous environment fast enough, but thats not the point) also, i am pretty sure, that this multiverse-theory is BS. i might be wrong about this (i am not a theoretical physicist^^), but I always thought that the state of the particle at the time of the interaction actually IS determined; we are just not able to predict the state of the particle, because it is impossible (for us) to gather all the data needed, so we have to rely on probabilities (until we can observe a certain state). now, if this assumption is correct, there are not multiple possible states, so there is no reason for the universe to split.

What people fail to mention when talking about quantum superposition using Schrodinger's Cat is the difference between a classical bit of information (like a computer bit being on or off) and a quantum bit of information (a qubit). Both bits produce one of two outcomes when queried (measured), but a classical bit has only one measurement possible while a qubit can be measured in many different ways (infinitely many, actually), each with two possible outcomes. For example, when you pass an electron through an inhomogeneous magnetic field, the electron is either deflected towards the North magnetic pole ("up") or towards the South magnetic pole ("down"). You can orient the N-S magnetic field in any direction you like and the electrons will still give one of those two outcomes, so electron spin is a qubit with two outcomes of spin "up" and spin "down" relative the the N-S magnetic field. Now suppose you pass electrons through a N-S magnetic field oriented vertically and then send those that were deflected "up" (literally up in this case) to a N-S magnetic field oriented horizontally. What do you expect to find? Well since the electrons have vertical spin up and spin is a vector (picture an arrow pointing upward here), then you probably expect the electron to pass straight through the horizontal magnetic field, i.e., they won't be deflected left or right at all ("up" or "down" relative to the horizontal N-S field). That's because the electron's spin vector (arrow) points up which means it doesn't point side-to-side (left of right) at all, so your horizontal spin measurement of a vertical spin up electron should seemingly yield a result of zero horizontal spin. But what you find instead is that 50% of the vertical spin up electrons are deflected left ("up" towards North pole) and 50% are deflected right ("down" towards South pole). True, 50% left plus 50% right *averages* to zero, but that's not what you expect from the measurement of a vector quantity in ordinary classical mechanics. [Aside: Quantum mechanics gives the classically expected results on average over the discrete or quantum measurement outcomes.] This is quantum superposition, a vertical spin up electron is a quantum superposition of 50% horizontal spin left and 50% horizontal spin right and we write that as |V+> = |H+> + |H-> (divided by root 2 for normalization, but I don't need that to make my point). The point here is the horizontal spin measurement of the quantum state |V+> produces each of its two "up"-"down" (left-right) results in 50-50 fashion. This is exactly what you hear people say about Schrodinger's Cat, i.e., you open the box and find the cat is dead with 50% probability or find the cat is alive with 50% probability. With that information alone, Schrodinger's Cat could be a classical bit or a qubit. If Schrodinger's Cat is a qubit, then there must be a measurement of the cat-box system like the vertical spin measurement of the state |V+> that produces |V+>, i.e., |H+> + |H->, with 100% certainty. We know the measurement "open the box" producing "Live Cat"-"Dead Cat" results in 50-50 fashion is analogous to the horizontal spin measurement of |V+>, so what is the measurement of the cat-box system giving |Live Cat> + |Dead Cat> with 100% certainty in analogy with the vertical spin measurement of the state |V+> that produces |V+> with 100% certainty? And what does its outcome mean physically? If you can't articulate that measurement and outcome of the cat-box system, and every possible measurement between that measurement and the "open the box" measurement, then the cat-box system is just a classical bit ... like flipping a coin to find heads or tails. No quantum superposition there 🙂 To read more about the quantum information approach to entanglement for the "general reader," see "Einstein's Entanglement: Bell Inequalities, Relativity, and the Qubit" due out in June 2024 with Oxford UP.

Fantastic video. Extremely simple to follow 🍻

This doesn’t prove anything.

Amazing videos you have here. Subbed.

Finally, I found the missing puzzle! Now I understand what happened in dark series

Very Good Explanation, thank you :)

Hello, I am undecided as to whether I subscribe to the "super state" theory detailed here, or to the theory that there's no breaking in the natural behavior of particles, but rather a breaking in our observation and data. To illustrate, I could play devils advocate and say that the cat in the box is already dead or alive, and the only reason I do not know is because I have not observed it. Anyway the video was great, thank you. As always science and theory will have to suffice until understanding takes hold. Here's hoping it happens in my lifetime, I'm ever curious.

This gives new meaning to "That was me in a whole nother life."

Well explained!

Thank you i get it now! This is amazing

Box: meow Schrodinger: ignore that
