Seeing your comment inspired me to make this

[-] thrawn@lemmy.world 25 points 2 years ago

This is a really high quality edit, I’m genuinely impressed. Probably not too much work mechanically but the attention to detail is great and someone who’s never seen it would probably think it was original. If I were a meme edit rater it would rank very high on my list. I don’t know how to make this comment not sound sarcastic or boomer-y but I actually really love this edit and will send it to people. They won’t understand it but that’s fine.

If they don't understand it, it's their loss.

Thank you so much, that's such a nice comment!! It took me about 20-30 minutes with paint.net :)

Holy shit, that's incredible.

This makes me irrationally angry

Now I'm just more angry...

Then just round your anger. You don't need that much precision.

is this what loss feels like?

[-] Blue_Morpho@lemmy.world 6 points 2 years ago

I collapsed at the sight.

[-] IlIllIIIllIlIlIIlI@lemmy.world 6 points 2 years ago

Im not going to explain this again... OK!... its not looking, its measure that changes the result of the experiment. To measure implies interaction.

[-] RememberTheApollo_@lemmy.world 97 points 2 years ago

I think the meme is just poking fun at the physics behind the whole thing, but in case anyone doesn’t know:

It’s called the observer effect, and it happens because:

This is often the result of utilizing instruments that, by necessity, alter the state of what they measure in some manner.

And particularly in the double-slit experiment:

Physicists have found that observation of quantum phenomena by a detector or an instrument can change the measured results of this experiment.

https://en.wikipedia.org/wiki/Observer_effect_(physics)

So for anyone who wants to have a surface understanding of the observer effect, the wiki does a fair job of the basic explanation.

[-] IlIllIIIllIlIlIIlI@lemmy.world 12 points 2 years ago

Yep, the observer it is not only observing, it is interacting in order to measure.

[-] humbletightband@lemmy.dbzer0.com 4 points 2 years ago

The meme is not about the observer effect or wavefunction collapse

[-] 0ops@lemm.ee 23 points 2 years ago

Yeah it is. From that wiki article:

A notable example of the observer effect occurs in quantum mechanics, as demonstrated by the double-slit experiment"

Super curious, and promise not to argue. What, in your summation, is the meme about?

[-] RampantParanoia2365@lemmy.world 9 points 2 years ago

Petulant electrons, I guess.

Maybe consciousness is fundamental and matter and spacetime are derived from it

edit: this comment is a bit controversial to people just want to say why not explore this idea we spent over 50 years on string theory where has that gotten us

Please just take the time to learn more before you come at me lol

[-] Cethin@lemmy.zip 16 points 2 years ago

Consciousness has literally nothing to do with it. In fact, the experiment as demonstrated in this emem would not replicate the double slit results. What has to happen is something along the path has to interfere with the photon (aka observe, which has nothing to do with consciousness, rather just an interaction), which causes the waveform to collapse. Basically, if something needs to know the state, the state collapses into one result. It doesn't matter what that thing is.

[-] K0W4LSK1@lemmy.dbzer0.com 3 points 2 years ago* (last edited 2 years ago)

Idk that would depend on what you believe is fundamental Fringe science baby!

[-] Cethin@lemmy.zip 11 points 2 years ago

Yeah, except we can do this experiment without ant consciousness aware of it even and it gets the same results. The only thing that matters is if the particle has to interact with something, because when it does it becomes a specific particle rather than a waveform. What that interaction is with does not effect the experiment in the slightest. A consciousness does not have any effect on the results of the experiment so there's no reason to expect that the universe cares about consciousness. To the universe, consciousness is yet just another series of interaction of things that behave the same as anything else, except it happens in a pattern that we think of as thought.

You need to qualify that statement somehow, or maybe give a citation or source that supports such an idea

[-] K0W4LSK1@lemmy.dbzer0.com 4 points 2 years ago

Sure firstly id like to say these are theories just as anything in science starts as. I am not saying this is fact by any means and could be totally wrong. here are some sources:

I'd read a piece that even just having a camera present has the same effect.

[-] bjoern_tantau@swg-empire.de 58 points 2 years ago* (last edited 2 years ago)

That's not really it. You need something that measures the state of the electron. Merely looking in the direction is not enough. It has to be something that interacts with the electron.

A camera alone isn't enough. But light (eg photons) with enough energy should be enough. But then that energy will manipulate the electron. If you had a completely dark room and pointed a camera at the experiment it wouldn't change anything.

It's kind of like having your cake and eating it too.

[-] OpenStars@startrek.website 24 points 2 years ago

Yeah, it turns out that slapping the electron around like with a big stick or whatever causes it to change its behavior, go figure! :-P

[-] sudoreboot@slrpnk.net 33 points 2 years ago* (last edited 2 years ago)

It isn't "looking" that is meant by "observation". "Observation" is meant to convey the idea that something (not necessarily sentient) is in some way interacting with an object in question such that the state(s) of the object affects the state(s) of the "observer" (and vice versa).

The word is rather misleading in that it might give the impression of a unidirectional type of interaction when it really is the establishment of a bidirectional relationship. The reason one says "I observe the electron" rather than "I am observed by the electron" is that we don't typically attribute agency to electrons the way we do humans (for good reasons), but they are equally true.

Edit: a way of putting it is that the electron can only be said to be in a particular state if it matters in any way to the state of whomever says it. If I want to know what state an electon is in, it must appear to me in some state in order for me to get an answer. If I never interact with it, I can't possibly get such an answer and the electron then behaves as if it was actually in more than one state at once, and all those states interfere with each other, and that looks like wavelike patterns in certain measurements.

Edit 2: just to be clear, I used an electron as an example, but it's exactly the same for anything else we know of. Photons, bicycles, protons, and elephants are all like this, too. It's just that the more fundamental particles you involve and the more you already know about many of them, the fewer the possible answers are for any measurement you could make.

[-] Tar_alcaran@sh.itjust.works 9 points 2 years ago

So you're telling me the people from The Secret lied to me?!

[-] sudoreboot@slrpnk.net 12 points 2 years ago

I have no idea what that is so I'll just go with yes, probably!

[-] jlh@lemmy.jlh.name 11 points 2 years ago

No, the electron only understands sentient thoughts, if a camera or an animal looks at it, it won't work.

[-] kuhore@lemmy.world 12 points 2 years ago

Well that's not right

Physicists have found that observation of quantum phenomena by a detector or an instrument can change the measured results of this experiment. Despite the "observer effect" in the double-slit experiment being caused by the presence of an electronic detector, the experiment's results have been interpreted by some to suggest that a conscious mind can directly affect reality.[3] However, the need for the "observer" to be conscious (versus merely existent, as in a unicellular microorganism) is not supported by scientific research, and has been pointed out as a misconception rooted in a poor understanding of the quantum wave function ψ and the quantum measurement process.[4][5][6]>

I suspect it was a joke. Can't be sure though.

[-] Cethin@lemmy.zip 4 points 2 years ago

I'm pretty confident it's a joke, but clearly from other comments people may actually believe something like that. It's best someone corrects it, even if not for the sake of the poster.

[-] Blue_Morpho@lemmy.world 5 points 2 years ago* (last edited 2 years ago)

Not just sentient, but intelligent thought. I proved it in university. When I setup the lab, I got no interference pattern. When my more intelligent labmate did the setup there were fringes.

Wait! That means I was the sentient one! I was cheated! (Or maybe I just sucked at lab.)

[-] Zerush@lemmy.ml 12 points 2 years ago

In short

😐 = Electron if you look

= Electron if you don't look
