"I Don't Think It Means What You Think It Means" examines scientific theories that have taken on a life of their own in popular culture & we help you understand what they really mean in scientific terms. Today we take on Schrodinger's Cat, the famous thought experiment by Austrian physicist Erwin Schrodinger.

While I'm aware that Schrodinger didn't intend for it to be interpreted this way, I find this analogy is also interesting from a philosophical standpoint, illustrating the uncertainty of existing in the universe. Because like the cat, we are mortal creatures who will inevitably die, eventually, but unlike the cat, we have some limited control of our surrounding as well as other lifeforms. But even still, our control over and understanding the universe as a whole is ultimately very, very small indeed. And some things are ultimately up to chance.
I'm a 12 yr old teaching myself about quasi stars, quark stars, neutron stars, black holes, everything atoms and everything microbiolgy, but yet I always come back to good old schrodinger.. I'm actually wearing a "wanted, dead AND alive schrodinger cat shirt lol good old days when I learned about schrodinger
The particle died and the counter tripped the hammer but the cat seeing the hammer fall thought it was a toy and jumped over to grab the hammer and play with it and therefore knocked the bottle of poison out of the way and saved it own life. How is that for a twist.
technically, until you observe the cat, it IS both dead and alive, because you can't observe it being dead or alive until the end- when you know when it is dead or alive. Technically, all of reality is in a state of superposition because you wouldn't know it until, so it will be all possible outcomes.
if the theory was true, and you placed a camera in the box, you would be observing it, and the superposition would break right when the cat were to die/not die, instead of when you opened the box. However, the theory couldn't work because a camera is really just an object, and would act the same as any other object inside the box would.
Is this experiment psychological or science? How is this profound and what science is there to back up any of this... What proof is there that the physical universe can't exist and function without the observer?
An I the only one who's really annoyed that the acronym for "I don't think that means what you think it means" has an I where a T should be?
Edit: just realized that it stands for "I don't think that it means what you think it means" even if Hank says something else
Shroediger's cat is a plagiarised ancient Greek myth, where Apollo was asked if the bird in one's hand is dead or alive, to which he responded, "it is both or either right now, and up to your perception of my answer to determine its reality". At least the Austrian should have had the dignity of citing his sources of inspiration, just like Newton, who "stood on the shoulders of giants".
But how does quantum mechanics determine what's being observed? How is the human's observation more valid than the cat's observation? How do we know that it was in a state of superposition if we can't observe it to see if it is without it collapsing? How do we know this isn't just probability and at some point the cat died like normal? Why haven't we tried this in real life with a rat so that PETA doesn't throw a fit?
Watching this video lead me to googling "superposition", which in turn shows me a picture of some ducks which triggers me to remember my dream in which I had several mallard ducks in my bed that I was trying to protect. Why was I dreaming about ducks?
I've always liked the Discworld answer to this--that the cat can, in fact, be in _three_ states: alive, dead, and BLOODY FURIOUS! Actually that last one is probably the most likely. :P ("Are you okay, kitty OW MY FACE!")
The result is only concomitant with observation? Wouldn't that mean our experiments we're capable of performing at this point in time are pretty useless and don't really tell us anything about quantum states at all? Maybe quantum states are more like multiple dimensions than A/B outcomes.
He just makes things complicated.
What the Fuck man? Why don't you just open the fucking box to know the answer??? Fuck Shrodinger and fuck his works about that shitty garbage people call "Quantum Mechanics" that people believes in
How is this complicated? The Radio Active in the box will slowly kill the cat, then the poison will accelerate the process, I don't get it, the Cat will die anyway, because it's mortal, radio active "on" will affect the cat, radio active off will not affect, this superposition will affect the cat slowly even if the poison is not triggered, which it will. Example, touching a fire, then pulling out, touching, pulling out, your hand will eventually suffer from the added outcome damage. This is why I hate philosophy, y'all wanna talk for no reason.
"According to Schrödinger, the Copenhagen interpretation implies that the cat remains both alive and dead until the state is observed. Schrödinger did not wish to promote the idea of dead-and-alive cats as a serious possibility; on the contrary, he intended the example to illustrate the absurdity of the existing view of quantum mechanics"

I think all that stuff about the "can't be observed" stuff is bs. Living organisms aren't some special entity where the atoms act weird when we aren't looking and then bam, just like that, your dead cat is still in the microwave. I think matter is normal and stays the same unless acted upon. However, living beings could also be wrong, and everything we see is an illusion, and that the cat is always not in the microwave.
i found out about you in class in one of your video's about chromosomes. I really enjoy science now because I watch your videos to get me pumped for the class and ever since my grade went up! I wanted too thank you.
this is crap,why 2 cats ,if so everything goes 2 places,why not 10 cats some with fleas some that stink ? its rubbish,its the garbage scientist stand on as facts that are garbage while science dissects the same from over and over , living theory's as facts , they are absolute morons .
+Scishow One would think something cannot be a particle and a wave at the same time. It seems easier to image that the particle in fact is a particle. And that some extrenal force makes it act like a wave. f.e. the fabric of space is like a river. A river that is moved by gravity. So I can imagine it is possible that the force of gravity exerts force on the river of space/time which in turn exerts force on the electrons with their tiny mass, which makes their movement subject to the motion of the space river. A way to confirm this, is by performing the double slit experiment in space (i am an optimist , yes) or in places with slightly different gravity circumstances, because of lower gravity the distance between solutions of the probability waves should be lower. Any more news on this subject available.
The class of drugs that Levitra, Viagra, Stendra, and Cialis belong to are called PDE5 inhibitors. They work by relaxing tight blood vessels, allowing more blood to surge into the penis and cause an erection, says Gregory Bales, M.D., an associate professor of urology at the University of Chicago.
The little pills do the trick for more than two-thirds of men with Viagra protects the heart (ED). They also work for guys who simply need them for a short time to get their “confidence back,” says Michael Eisenberg, M.D., director of male reproductive medicine and surgery at Stanford University.
