Austrian physicist Erwin Schrödinger, one of the founders of quantum mechanics, posed this famous question: If you put a cat in a sealed box with a device that has a 50% chance of killing the cat in the next hour, what will be the state of the cat when that time is up? Chad Orzel investigates this thought experiment.
Lesson by Chad Orzel, animation by Agota Vegso.
Your crush actually likes you and doesn't like you at the same time, until your curiosity makes you approach her.
... then she rejects you and you're dead inside while being alive
Hmmm.... I was not able to understand the video ... Until I saw this comment ... Thnx btw
Nice!

I love how schrodinger discovered the fundamentals of quantum mechanics and then just went "this is bs, im doing biology now"
As you advance in any field, the boundaries between them start to frazzle and knowledge and interest become monolithic. He never changed subjects, just focus.
most of science is just bs that just makes the most sense of all the sea of bs
Valid
bababoeey whats bs
Not true cat actually makes sound from time to time so if you woudl stand close to the box you would know wheter the cat is dead or alive, no superposition.
You could show me this video like 10times and even if i payed real attention to it i could never understand it to the point where i would be able to explain it to someone. This is beyond the intellectual skills i could ever conquer in my whole life.
The reason why you should be afraid of physics and chemistry
I heard one famous scientist said if you find science boring, you’re learning from the wrong teacher. It’s either he doesn’t want you to learn or he doesn’t fully understand himself, explaining like an AI.
@@safaeit This isn't about finding science boring (well perhaps for this person it might be), it's about understanding it
I really dont understand intellectual but ok
In fairness it's dumbed down to the point it forgets to explain anything
so if you open the box and the cat is dead, then your curiosity killed the cat
It is not like that , it is more like , the cat is already dead and alive but you are able to see one of them.
The joke
Your head
Renee Claude My dog is named Curiosity
Even if you dont look, its either dead or alive so for instance if you dont look and its dead you just never know but its dead anyway. I mean our observation wont determine the cats situation right? That takes place anyway wether we look or we dont look.
Or, y'know,
The curiosity killed *your* cat
Schrodinger: there is no way that you can tell if the cat is alive or dead without opening the box
Cat: *meow*
Schrödinger: ...
😂😂
Ok cat is alive
Actually it's more like observing which can be by hearing, seeing........etc
This is the best!
Proceeds to shoot the cat
A lot of people in the comments are missing the point. The point isn't "we don't know until we open the box". The point is that the cat IS both alive and dead until we open the box, which forces it into a definite state of one or the other.
The point is that our interaction (which is a placeholder for measurements in physics) influences the outcome and changes the behavior of the entity being interacted with/measured into a definite state.
So is the cat ded or alive? Am damb
Thanks. Your comment made it very easy to understand.
Forgive me but I've always been very confused about Schrodinger's Cat. How can something be both dead, and alive, simultaneously? If, to be alive, we must be consciously aware, have a heartbeat, etc., how can it be that we both have and lack consciousness, a pulse, and the like experiences? Schrodinger stipulates in his thought experiment that there is a 50 percent chance that the cat will be alive after the hour, and a fifty percent chance that it won't be alive after an hour. How does our interaction influence the outcome of the scenario? It seems to me that whether or not the cat is alive or dead is not ontologically significant. The cat's being alive is only epistemically significant, it seems to me. By that I mean that whether or not we observe the cat makes no difference as to whether or not the cat is dead or alive. It only matters insofar as we can *know* that the cat is dead, or alive. Is this not the case? And, if Schrodinger's Cat is only epistemically significant, why is that point not emphasized? It seems they threaten the fallacy of equivocation by not specifiying.
Maybe I'm just missing the point. I don't pretend to be well-understood insofar as science is concerned (let alone a physicist), and I admire those who are. I would appreciate someone simplifying the Schrodinger's Cat thought experiment to the level of a child, while retaining its precise meaning, for me.
@@Rspknlikeab0ssxd the thought experiment is not about the cat but the fact that until we directly observe the object, the object is it two states at once when talking about quantum mechanics as far as I understand it. The cat could just as easily be a coin with a machine that flips it inside the box. Is the coin on heads or tails? No, the coin is one ~both~ heads & tails until we observe it according to quantum mechanics.
@@jinolin9062 So then, as I am understanding what you're saying, quantum mechanics is inconsistent on logical grounds. For, it is inconsistent for something to be both alive and dead, heads and tails, be or not be, yes and no, etc. simultaneously.
"I don't know if the *cat* is dead or alive until I open the box"
"Meow"
"Shut up"
schrödinger: doctor, how is my cat doing?

Let's appreciate the quality of animation used to design and explain quantum mechanics in a better way. It's extremely helpful for all the students studying it in academics. Good job :)
Good review lol❤
2:25 I’m learning this right now. Suppose you put a detector on both sides of the slits that detect which side the particle is coming from. It will not act as a wave function anymore, but as a particle. Take away the detectors and then it acts as the wave functions again. Quantum physics/mechanics is cool.
Isn't it a phenomenon
ohh yea the good old double slit Exp
is it because the observer affects the outcome itself ?
my father explained it to me cause he's obsessed with physics and i think its really cool
@@mohamedalhusni6255You can think it in this way
When the particle doesn't interact with matter it acts like a wave.
But when it interacts with matter it behaves like a particle

Schrodinger:shut up!
@@frazzydoof770 technically since he did not die in the box this is not correct let me explain he was dead before hand so he would not have a chance to be alive if the box is opened there is only one outcome in that instance also his funeral was open casket so no schrodinger's cat theory was used on the funeral but you didn't know that so technically this was a schrodinger's cat theory example his funeral had a 50% chance of being open casket and a 50% chance of not me telling you it was opens the box to find your cat alive glad i saw your comment made me exercise my brain a bit 😁

This was a nice, clear explanation. Of course, I still don't understand the idea of electrons being shared among atoms, as is claimed in this video. In school, I was taught that electrons spin around the nucleus of atoms. So if they're moving from atom to atom, it sounds like they are not (?).

Quite nice explanation!!
Well, the cat certainly knows whether it's dead or alive, even if Schrödinger doesn't. And every particle in the universe knows exactly what its doing too, even if we can't describe it. Schrödinger's problem seems more about detection & semantics than it is about some state where things are both A and --A until someone peeks

+Enigma It's pretty straight forward.
Are you the center of the Universe or is the Cat?
I don't believe that the cat is irrelevant as Schrodinger does.
Let's say a human straps a cat to a table forcing it to view a box wired with a 50/50 life/death chance.
The human then climbs in the box which can only be opened when the cat meows.
Does the human sit suspended between life/death until the box is opened? Of course not.
The human died or survived the moment the lid closed when they got in.
Eye Heisenberg
I have a simpler explanation, however, I'm not sure if it's right or not.
Again, we have a cat. Now I pull the pin of a grenade, shove it into a specially-made box along with the cat, then shut the trap. This grenade, however, is special because it has 50 percents of exploding, thus killing the cat, and 50 percents of malfunctioning, rendering the cat safe. This box here, is soundproof and is indestructible, so absolutely zero information can pass onto us - the observers. The only way to see the final fate of the cat is to open the box - or measure it. This is where it got interesting in QM. BEFORE you open the box, there's an imperative 50/50 chances the cat is either dead, or alive, so during that time where we know zero information of the cat's fate, we can say that it is, in fact, half dead and half alive.
So to be exact, the cat is in superposition of being both dead and both alive at the same time BEFORE you measure it, or open the box. When you open the box, or measure the cat, the result will collapse back into a single state, making the cat EITHER dead or alive, and not both.
This is a weird way of thinking, because in normal, rational way of thought, the cat is either dead or alive, there's no such thing as being both. Or the grenade either explode, or not and only one single result can be deduce even before measurement.
Matthew Clifford That is the same as Schrodinger's Cat but with a grenade.
The cat is either alive or dead whether we know it or not.
Our ignorance of a fact either way does not make this "cat is in superposition of being both dead and both alive at the same time" caper of Schrodinger true except in his own imagination.
no one:
Schrödinger: *hehe unboxing time*
🤣🤣🤣🤣🤣🤣🤧
M-m-m-money shot
Actually in the double slit experiment they recently found that the particle goes through one of the slits but the wave function goes through both then affects the particle on the other side, it also shows that sometimes the particle doesn't go through any slit but the wave it rode on did and still had an affect on the results..... So basically the act of measuring the test is enough to mess w/ the results, I feel like the only way we'll be able to see what's really going on is if we start trying to come up w/ a magnification device that doesn't use electricity because even at that scale, a small amount of energy is tantamount to trying to hear a flea crawl on a guitar string while someone is playing Through the Fire and Flames by Dragonforce on the guitar at the same time. 😂🤣

If Schrödingers cat had 9 lifes, would it then be alife and 1/9th dead at the same time?
The wave nature explanation should have been told after you had given the second case that if one slot is blocked the pattern doesn't appear then you as a conclusion could say so the Patten with 2 slits say that the wave nature is formed and all ...etc etc
What if you had a camera in the box?
*Physics left the chat*
DoodleDan hahaha. But the reason we can't have a camera is that for something to get into a superposition, it is required that it must not be watched, heard, speculated, or recorded in any way. Otherwise it can't enter a superposition.
The universe has a secret and it wants to keep it
DoodleDan then you have observed it, and by using your curiosity you have either killed or kept the cat alive.
It's not really about observation. It's about interaction with other particles. So Schrödingers cat would never work. It always is in only one position, namely dead or alive.
Kai but schrodingers cat was namely an example of superposition no?

Its best to just accept the theory and not think too deeply about it as unfortunate as that sounds. Ill let the theorists keep themselves up at night and spare myself the heartache lol. The theory is very possibly incomplete and I like to believe there are hidden variables that solve these issues.
.. So far no hidden variables have been found for a century!
Yes, but each of those experiments only tests one hidden variable. If you try to prove all hidden variables dont exist by proving case by case, then youll never prove they dont exist because you need to do it an infinite number of times.
Me: What do you have in that box?
Schrödinger: A cat
Me: Alive or dead?
Schrödinger: Yes

Person 2: cool cool, is it alive?
This reminds me of online distance learning.
I'm on the classroom, but at the same time, I am not. Literally and figuratively.
For those already initiated in QM I repeat here some comments previously made to similar videos. They may clarify debatable points.
The Schrödinger time dependent equation (STDE) when applied to a wave representing an initial state of, say, an electron bound to a proton and together forming a hydrogen atom, predicts and retrodicts all the future and previous states of the electron wave, in the same fashion than the evolution equations of classical mechanics predicts the movement of the Earth around the Sun. Note that the STDE is energy conservative, that is, the initial state as well as the predicted and retrodicted ones all have the same energy.
As is well known the bound electron has a completely different conduct. Whatever the initial state and in absence of other interactions an excited electron will settle in a stationary state radiating energy (in the form of a photon) along the way. If the stationary state is the ground state the electron will stay there forever (in absence, as said before, of other interactions). Otherwise the stationary electron state is ephemeral and will be abandoned to radiate a photon and assume a new stationary state of even lower energy. This "down the staircase" process repeats until the ground state is reached. There is no manner to adapt the STDE to this physical process. This inconsistency was discovered by none other than Niels Bohr, as can be inferred from the report of Werner Heisenberg. See our note
www.researchgate.net/publication/356193279_Deconstruction_of_Quantum_Wave_Mechanics
After discovering the tremendous inconsistency between the equation and the atom it would have been natural to announce that the STDE contradicted physical facts, and ask for a correct equation. I assume as true, but only know from hearsay very long ago, that in Einstein's viewpoint the correct deterministic time dependent wave equation had to be non-linear in contrast with the linear STDE. References to this historical detail would be appreciated.
It is hard to believe but, against reasonableness and common sense, Bohr decided to adopt the STDE as correct and that continuity, causality and determinism of physical processes were wrong because they contradicted the STDE. Apparently mathematical equations on paper were more relevant than the experience of the whole human race. Then a series of new and fanciful "quantum physical principles" were adopted.
In my opinion the powerful quantum establishment dogmatically defends Quantism and strongly rejects any attempt to correct its misdeeds, even if the correct deterministic time dependent wave equation is available.
With best regards to all
