The word “observed” has largely been conflated with human perception in the layperson’s understanding of quantum mechanics. When they were first experimenting with the dual slit experiment, they were simply trying to make measurements to predict where an electron might end up after entering one of the two slits. However they soon discovered that their measurements changed the behavior of the electron. That behavior has been denoted as an observation however observation is very vague.
It’s better to say “a measurement which causes a wave-function collapse” rather than an observation. When phrased that way, it feels a lot more explicit and it allows lay people like myself to ask the next question “what causes a wave function to collapse?”
Source: I just asked my physics PhD wife about this a couple nights ago and she did her best to explain it to me.
If anyone can explain what exactly causes the wave function to collapse, id appreciate it. Because I can’t understand anything I read online.
Also this meme checks out. A person could observe their CPU with the right conditions and instruments to cause a wave function collapse. But I believe a Qbit can reset its state no?
If you use your eyes, nothing happens. Most people think “observe” means they can just look at the experiment and expect it to change. That’s why so many people end up in metaphysics thinking their own perception has any impact on the outcomes of physical states. In reality, it makes no difference.
To observe it you have to interact with it in some way. This mean in order to “see” it you need to shoot some photons at it or send some radio signals which will reflect. It all has an influence.
So the problem is not “observing” in in some philosophical sense. The problem is that you need to interact with it in order to “observe” it.
It’s the interaction that makes “wave function to collapse” not the fact that you observed it.
Perhaps the wave function always collapses no matter what, but the way it collapses changes? If there was no screen for the photons to interact with they’d continue to act like waves but since there’s a screen they collapse at some point on it dictated by the wave. And if you try to observe how they end up there you end up collapsing it earlier so where they go are dictated by the earlier state of the wave.
The Schrödinger equation is a multi variable second order partial differential equation. You end up with a “position operator” and a “momentum operator” (momentum is mass times velocity, so we focus on the velocity bit). Because of the way that taking a partial derivative works, you end up applying one you can’t get the other.
Idk that’s probably a terrible explanation (I got a C in that class lol), but it is really cool when you see how the math works.
For a mathless explanation, I believe it’s because in the quantum world all the atoms that interact are part of the same system. That includes the ones that make up the instruments and the scientists themselves. If you put the photons in an experimental apparatus the results can change because the system is different. Meaning you can influence the waveform collapse simply by experimenting to try and understand it.
I hope that’s right I watch a ton of physics YouTube, so I hope I’m absorbing some of this stuff.
For more crazy shit, see how photons traveling across the universe cause the electron they originate from at the start and the electron they terminate at the end to agree to exchange that energy across space and time. It’s mind bending. From the photon perspective (at the speed of light) a journey across the cosmos is instantaneous. No time passes for the photon from its frame of reference.

Many people are trying to give a definitive answer, and there are good theories, but honestly, it is still very much an open question. There are multiple interpretations and as people tend to do in popular science, some spread their opinion as a fact, but we don’t have one correct answer.
Say you were a spy, and you think there’s a laser guarding the largest diamond in the world.
There’s no way to detect if the laser is there without putting some form of matter in the way of the laser. Be it a hand, or spray bottle.
Now at the museum, a mist won’t set off the alarm, but you’re still reflecting some of the photons out of the beam and into your eyes. Otherwise you wouldn’t see the beam…
But for a quantum experiment, where we care about each individual photon, spraying a fine mist will affect the experiment. Sticking anything in that laser beam path will affect the measurement.
So how do you make a measurement without interacting? As far as we know, you can’t.
All the people who are not choosing to chill with a usually calm intelligent mammal because “snakes will get out of your way” apparently don’t know shit about black mambas:
Skittish and often unpredictable, the black mamba is agile and can move quickly. In the wild, black mambas seldom tolerate humans approaching more closely than about 40 metres (130 ft)
When confronted, it is likely to engage in a threat display
During the threat display, any sudden movement by the intruder may provoke the snake into performing a series of rapid strikes, leading to severe envenomation
Give me a big strong dude intelligent enough to leave you alone after you’re demonstrated that you’re not a threat any day!
The black mamba’s reputation for being ready to attack is exaggerated; it is usually provoked by perceived threats such as the blocking of its movements and ability to retreat.
Despite its reputation as a formidable and highly aggressive species, the black mamba attacks humans only if it is threatened or cornered.
As long as you’re careful about displaying submissive body language and not getting too close, the worst thing that could happen is probably that he gets to snack on fruit and ignores you 🤷
Probably have to REALLY know what you’re doing though lol
Try finding a door that can withstand a gorilla tho
The gorilla won’t even care that you’re there as long as you don’t get too close and act too aggressively. It’s definitely not going to hunt you down and break down the door to get to you unless its family is in there too or something like that.
Also, as I pointed out to the other one, being locked in a bathroom for 24 hours is its own kind of hell for some of us.
Besides, one of the snakes might be hiding in that bathroom and you won’t know until it’s too late. Silverback gorillas, on the other hand, are not known for stealth.
Nah, that’s lawyers you’re thinking of. Gorillas are the ones who howl at the moon and have been observed by Warren Zevon casually strolling around all over London.
The solution to global warming, then, is clearly to just set up a massive ring of fans all pointed in the same direction in a ring around the North Pole, to keep the jet stream going
Isn’t that literally just a thinly veiled Futurama reference? Like, there was an episode where planet Express was sent out to fetch ice from Haley’s comet to dump in the ocean to combat global warming which fails and they end up just pushing the earth farther away from the sun to cool things down?
My daughter starts a new online school program and I have to be a “learning coach” which basically means I have to keep an eye on her during the school day and help her when she needs it.
I think it will be very difficult, but rewarding. Going down to a single income sucks, but she had to be taken out of school because of some serious bullying. I just hope this will make her happier.
This thread went longer and more serious than I could’ve imagined at the outset. Glad I stuck with it! Congrats on the mod role (maybe I’m late to notice?).
Sorry to hear about your daughter and income situation. Kids, and the parents that raise them that way, can be such di**s.
Thanks for all of that. The mod thing was a surprise to me. One day, I was a mod. No one asked me. And that thread is getting dangerously close to the maximum number of posts Discourse allows.
Yes, no one is immune to propaganda in the sense of misinformation.
Ads on the other hand… The often quoted subconscious working of ads just doesn’t work on me: i choose my müesli based on parameters (like texture, taste,…), not on whims! So ads go on one side in, out on the other.
Have you considered those ads simply aren’t targeted at people like you but at the mainstream instead? And that you may well still be susceptible to adds targeted at your kind of mindset?
Have you considered those ads simply aren’t targeted at people like you but at the mainstream instead?
Yes, that’s what i said?
And that you may well still be susceptible to adds targeted at your kind of mindset?
You mean ads for products i would choose based on my need and their qualities? Gladly. But im rather careful with my privacy and see ads only on the street, so there’s that.
It’s called subconscious for a reason. You aren’t concous about it.
How do you know that you choose your muesli based on parameters, when things like taste are influenced by the brand and design of the package. No this is not a joke and there actually have been studies on this.
Preconcusness isn’t the subconscousness but only things that you aren’t councious of right now but that could be brought into consciousness
It literally isn’t the same thing
Edit: they edited their comment and now my comment doesn’t make sense anymore. They said that the unconscious is an outdated term and we should rather use preconousness and that they are way more conscious about everything than everyone else.
There’s health a big consideration, since it’s something almost daily. So 5-corn with wholewheat flakes and fruit it is. Next convenience store has only one brand of it.
Well I don’t care about my food that much that I choose my cerial on most healthy option. I eat what I want when I feel like it. As long as I don’t eat only unhealthy food this should work out. And if I get to 100 or only 80 because of tthat I don’t care.
I don’t think most people who qualify as experts on this matter are doing that in the slightest… but ok buddy. Let’s group the politicians and scientists together then?
The whole point of the scientific method is that it’s self-correcting. Corrupting one scientist doesn’t matter because the scientific consensus will show that they’re wrong.
But corrupt one (or a few) politicians and you can get laws changed for your benefit.
Greta Thunberg probably does too, with all the places she speaks and demonstrates at. I’m not going to take issue with it though because her whole thing is advocacy and protest. Just the same, I’m not going to take issue with scientists going to conferences, where they discuss the latest climate science and green technologies and projections, and issue joint statements calling for changes.
This isn’t meant to be a gotcha. And the experts are certainly scientists of some kind, or in medicine. The article itself clearly isn’t, and if they’re being genuine it was in very poor taste. The headline should’ve been about ways to cope with the heat, not about how we’re about to adapt to heat. The latter has unsaid connotations.
My point is that you shouldn’t discount the scientific experts based on air travel. The other “experts” can go fuck themselves though
The motion blur is what is most characteristic of AI. Also the horses lack of shadow, the nonsense text on signs, the fact that there’s a horse in a convenience store.
Ich habe Dinge gesehen, die ihr Menschen niemals glauben würdet. Gigantische Schiffe, die brannten, draußen vor der Schulter des Orion. Und ein rosa fliegendes Schwein, genannt Pupsi, im Kino, nahe meiner 6-jährigern Tochter.
RFC 1925 (3) With sufficient thrust, pigs fly just fine. However, this is not necessarily a good idea. It is hard to be sure where they are going to land, and it could be dangerous sitting under them as they fly overhead.
