Shakespeare: “To be or not to be...” Schrodinger: “To be and* not to be...”

Everybody at schrodinger’s funeral: *hmmm*

I love how schrodinger discovered the fundamentals of quantum mechanics and then just went "this is bs, im doing biology now"

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.

Your crush actually likes you and doesn't like you at the same time, until your curiosity makes you approach her.

Schrodinger: there is no way that you can tell if the cat is alive or dead without opening the box Cat: *meow* Schrödinger: ...

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.

"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? doctor: i've got good news and bad news...

Is schrödinger trying to explain “I don’t know” with science

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.

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 :)

I understood the word "cat."

I will act like I understood everything

I would love a video on Schrödinger's "What is life?" answer. The definition he gave is one of the most beautiful and profound things I have ever heard

I watched this video first years ago as a child who was baffled by this; now, in my second year of my undergrad maths course studying quantum mechanics as one of my courses, this makes so much more sense!

Guess what the comment was by reading replies.

Me: So, is the cat alive? Schrödinger: Well yes, but actually no.

I've been puzzled by this for so long I needed to watch this. Explained it to me so well it seems really simple

This is one of the channel who help me to understand educational concepts. Nice explanation!

This is like the mystery of wether or not the refrigerator light stays on when the door is closed

Wanted Schrödinger's cat : Dead and Alive

Seeing this after studying wave optics in school and heard of this experiment in the big bang theory, science and universe is so vast and great, we never know enough and that's incredible

If we place these explanations Schrodinger's Cat and Quantum Mechanics into my brain, it melts.

so if you open the box and the cat is dead, then your curiosity killed the cat

My mom: you room is a mess Me: mom, that’s the superposition of the atoms. Until you opened the door my room was a non existence state. So is a mess and is clean at the same time. My mom:

I used Google translate to produce several recording of this explanation, including in; Yiddish, Swahili and Urdu. I then played them backwards, simultaneously. It made the whole thing so much easier to understand.

이번 영상으로 슈뢰딩거의 고양이 실험을 제대로 이해한 기분이 듭니다. 각종 미디어에서 많이 다루는 주제이지만 대부분의 사람들이 잘못 알고 있는 실험인데, 저 같이 양자역학을 공부하지 않은 사람도 이해할 수 있게 영상을 만들어주셔서 감사합니다. 좋은 영상 감사합니다!

Schrödinger’s Cat walked into a bar. and doesn’t.

"To be or not to be, that is the question" - Schrödinger's cat

Ah got to love a video that explains everything and nothing all in one go 😌

The 1st time I heard this theory I didn’t get it so I forgot it. The 2nd time I heard it I completely understood it in a few different ways. It’s Genius.

That moment when you drop your iPhone face down. It's both cracked and not cracked at the same time until you check.

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

that flew over my head ,am watching it again

Amazing explanation. Thank you.

no cats were harmed in this experiment - or were they..

Schrödinger: did you die? Schrödinger's cat : yes. Schrödinger's cat : *But I Lived!*

Great explanation. Thanks for sharing.

The process brought back my focus, not my lack of feeling

“So is the cat alive or dead?” Schrödinger: *yes*

Teacher: so you understand superposition now? Me: I'm in a superposition of understanding and not understanding.

I was very confident that i understood and felt proud till this man brought in wavelength and what not. (note: i am not complaining tho it's just that i will have to rewatch that part and make my brain connect what he is saying and understand)

3:16 An atom in two different ordits seems wierd, but two ordits can be in one place and the atom can ordit both of them. Means the two nucleus are spinning and atom is standing in one place. That explains this right.

A student goes to the library an asks the librarian if there are any books on Pavlov's dog or Schrodinger's cat. The librarian says "That rings a bell, but I'm not really sure..."

Schorödinger’s cat went into a bar And didn’t

This means we should close our loved once in a box and leave them there and as long as we dont open it, they are gonna be with us forever.

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 (?).

So, did the cat survive? Schrödinger:Yesn't.

When you're sleeping the world doesn't exist until you wake up

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 Daniel Crespin

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

“What we know is a drop. What we don’t know is an ocean”

‘Is your cat alive?’ Schrödinger: ‘Well yes, but actually no.’

Most videos, have not stressed me out , until now

Totally off topic but the lil transistors are SO CUTE. I WANT ONE AS A PET FR. 3:59

My PhD interviewer: What is schrodinger's cat thought experiment? Me: To me, I'm both selected and rejected for the admission until you tell Interviewer:

is the cat dead or alive? Shrödinger: yes.

Excellent explanation really

I am glad I understood this video better than ever after 3years and a physics degree.

Well, I’m alive but dead inside

Feels like u were taking about the cat in the first minute, but then changed subjects, but didn't at the same time...

This is the same as sending a snap to your crush asking if y’all can go out on a date and getting a snap back.. the answer is there but you won’t know until you open it. And in that moment you u feel what Schrödinger felt.

Awesome work!

I can't be the only one who understood absolutely nothing

no one: Schrödinger: *hehe unboxing time*

Nicely explained!

this just integrated so many of the chapters I learnt in 12th! 🤯

Video: *ends* Me: I didn't understand anything but loved the animations

There is food in your fridge until you open it. *Boom.*

Quite nice explanation!!

Thanks for the video.

All I understood was the story of the cat put in a box

0:52 what seems absurd is that the cat has two tails.

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

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. 😂🤣

Schrödinger got pulled over by a cop. The cop look in the trunk and said "do you know there's a dead cat in the back?" "Well now i know, jerk"

When you swim near the shore of the sea of knowledge and then venture to go out a bit deeper ... and drown in it.

Kind of creepy that I’d never heard of Schrödinger’s cat until it was mentioned on TV last night - and today it’s on my KZfaq front page!!!

My physics professor taught us this he then asked us to see physics as philosophy to understand and told us to read "bhagwat Gita" we did and then in further lectures he said so guys we all exist as wave and particle , so alignment of your energies is very essential

Schrodinger's cat Wanted Dead or alive

I've never watched a video that legitimately stressed me out until now

It is all about the quantum mechanics postulates in where the ket that describes the state of the sistem in that moment, which is the state of the cat, has two options before we measure it:either the cat is dead or is alive. After we measure, or in this case we check the state of the cat, that duality disappears

One point being missed out here, is to define what it means to observe a state. As for the cat, the superposition ends with the box opening, but what is with the double slit? The importancy here is that it doesn‘t need a human to measure the state. Because the measurement takes place on the screen, where after the two waves from the slits have already interfered and the electron has to take one of the constructive interference sites. Then you may understand why the experiment will give you no more interference pattern when a detector is placed at the slits, as it measures at this point already which slit it takes, thus no interference is possible.

Damn i wish i wasn't an idiot and could understand shit like this! :D

“Famous for something he never actually did” Christopher Colombias: Hold my Smallpox

Sheldon and Leonard taught me so much!

what a great explanation

I could understand it until he said “superposition”

Most of us are like Not understanding a single thing Watching the vid Lying in bed Reading comments for the conclusion

Thanks for explaining Schrodinger's Cat.....it was helpful for me to realize that I don't understand Schrodinger's Cat

Yes! Another intellectual video that I can't comprehend!

Me: Is the cat alive or dead? Schrödinger: Yes

Im kinda impressed at my ability to come back to this video every year and yet not understand this (Thx for the likes guys) Note: I did understand this it's pretty simple just confusing. can the comments bout explaining me how it works stop

Left school years ago and I still find the double slit experiment to be mind-blowing.

Thanks TED,

Imagine in another universe this experiment will be known as cat's schrodinger 😂

Before clicking on this video, I had a 50% chance of understanding it, but now when I DID click, I am Brain-Dead.

I'm still giving this video a like even though I understood nothing.

Wouldn’t the cat’s own thoughts and movements alter the probability of outcome? For observation to change the outcome, the cat would have to be both motionless and thoughtless (considering all other extraneous variables have been eliminated). Is a motionless, thoughtless object even alive?
