Personally I hate how similar the image and link icons are on the website. They’re both squares with diagonal lines through them. I’ve lost count of the amount of times I accidentally clicked a link instead of expanding an image.
So it turns out the original meme was kind of right? It just didn’t illustrate what it was talking about very well. According to @ada@lemmy.blahaj.zone:
The double slit experiment is about observation.
When you fire photons through the double slits, one photon at a time, they cause wave interference patterns with themselves as if each photon travelled through both slits.
Yet if you set something up to measure which slit each photon passed through, they no longer interfere with themselves, and give you the two straight lines pattern, rather than the interference pattern.
It’s clear he’s observing something, but all too easy for the viewer to think the monkey is merely observing the pattern on the screen at the end. It also doesn’t help that there are a bunch of slight variations on the double slit experiment, like those listed in this post.
If the monkey was at 90 degrees to the experiment, looking at the slits only side on, then it might be clearer - though I’m not sure how you could draw that lol.
The meme confuses two things in quantum mechanics. One is the double slit experiment, which confirms that light behaves both as a wave and a particle. That’s what the meme is showing here.
However it’s also throwing in Schrodinger’s, which states that until you look at something it exists in all states - the classic theoretical example being the cat in a box, which is both alive and dead until you open the box. That doesn’t make much sense in the real world, but when looking at quantum particles it is provably true.
Just to complete the set of “principles of quantum mechanics that people know of but don’t fully understand”, there’s the Heisenberg Uncertainty Principle, which states that you can either know the position of something or its momentum (ie where it’s going). The more accurately you measure one of these, the less accurate any measurement is of the other.
Edit: However there’s also what /u/Ada@lemmy.blahaj.zone said below:

So maybe the meme was referring to this variation on the double slit experiment, rather than Schrodinger.
Most routers can have VLAN functionality if you flash them with custom firmware. You get allllll the settings then. I have a netgear router that now has an FTP server and a bunch of other stuff. All you have to do is make sure the model you buy has a chipset supported by the firmware. Firmwares include:
DD-WRT
Tomato
AdvancedTomato
OpenWRT
Chilifire
Gargoyle
I’m sure someone will come in and say that using a consumer grade router is naff, but in my (somewhat limited) experience working with managed switches in an industrial setting, a custom consumer router is much more feature-rich. Unless you need the IO of a managed switch (ie SFPs) I see no reason to go down that route.
If you are using SFPs, be sure to get the knock off ones that can be programmed - there should be places that sell them and program them at no extra cost. They can literally be 1/10 of the cost of the manufacturer’s own modules.
Yes exactly. This story has echos of the guy who was hounded by police (and maybe even charged and convicted?) because he took a different route while cycling and rode past a house where a crime was committed. That, too, was Google.
The issue here is not that they are required to reveal search history of suspects, the issue is that the police is browsing the search history of everyone in order to find a suspect. That’s not what warrants are for and violates the constitutional rights of nearly everyone they searched.
It wasn’t specific to an individual criminal, though. Police aren’t allowed to get warrants for fishing expeditions, they’re supposed to find leads themselves and then get a concise warrant to evidence to confirm that. They searched people they had no right to search, and violated their constitutional rights.
They also tried to say that they asked the US to keep their ships away or at least tell them where the ships were. However, they didn’t ask this until after the boat was sunk.
