I've been researching into quantum mechanics and was intrigued by the concept of entanglement. The particles can be on the opposite ends of the galaxy yet the result of one instantaneously affects the result of the other. How is this possible?
So first off I apologize if my english ain't the best, but I'm not a native speaker. Now onto the story.

I work as primarily as a developer, but often also as a tech support guy, since I am the newest dev here.
I work for a company that is primary a web store, but we also have wood and brick stores, or what counts for them today inside shopping centers and we have a custom POS for them that is web based. It has connections to web front end, to apps and certain other things so it can do all kinds of things, but the problem as always are .... users ...
β
So onto the story. We have a special feature for the web store where you can enable certain clients to purchase up to user defined amount of products for free every X days. The HQ has been using this for a while, but one of the newer stores just started using this feature. I being the dashing and helpful dev helped them set it up and explained how the feature worked. After confirming that they knew what they were doing I let them be and got back to my regular work, so yesteday I got an email from them going something like this. $me = Me, $manager = manager of the new store.

Hello, $me
β
the feature that you set up for us to give some items away for free is not working, when we tried to use it we got a bill and now we do not know what to do. Please do fix it, I thought you said this works already...

So since I was busy with other work yesterday I didn't manage to look at the issue till today. First I tried the feature on localhost, then on dev server and it worked everywhere, I checked version control system and everything was up to date ... Hmmm, what could it be? So I went to check the logs ... Aaaand there it was. They created the bill at 12:15 while they set up the feature at 12:30 ... So I responded back kindly.
β
Hello $manager,
β
I have seen that you have set up the feature, but the feature needs to be set up before you start using it. Unfortunately since you already created the bill and sent it to your tax ministry you will need to send cancellation to your tax ministry for this bill and then use the feature.

Hopefully that will be enough. Sometimes I wonder about the state of humanity..
Edit: I found out why they were not using the module the way it was supposed to be used. They were trying to do something that is not exactly legal ... My hope in humanity is diminishing...
Mind uploading is one of the few things I am skeptical of. As seen in SOMA, scanning and running a brain just creates a copy. However, entangling every single subatomic particle in the brain with another set of subatomic particles could allow consciousness to be digitized or uploaded into a computer, since quantum entanglement effectively makes subatomic particles exist in two places at once, possibly allowing consciousness to be transferred from the brain into a computer, with seamless continuity. The technology to do that, however, is beyond me.
On the metaphysical angle, it is possible to exist again, popping out of oblivion without any knowledge of existence before (and I also theorize that anecdotal reports of "reincarnation" may simply be random chance of a false memory being formed from random combinations of particles), but that is even more unfalsifiable than my first assertion, which is already unfalsifiable to begin with. Still, I cannot rule out the possibility of a chance arrangement of particles smashing together to form "me" again, minus the memories of my previous existence.
Also, the introductory speech to the PBS Space Time episode regarding the Boltzmann Brain is excellent in saying that consciousness may be an emergent phenomenon/emergent property of an arrangement of subatomic particles, similar to the assertion that the Universe is a zero-energy universe formed from a quantum fluctuation (another kind of emergent phenomenon).
Something I have been wondering every time I read about quantum entanglement. (I am a physics noob, so please be kind)
If we can measure quantum entangled particles instantaneously over vast distances, why is this existing technology not already used as an instant transmission mechanic - by measuring binary states.
Entangled particle manipulated: true/false.
Add enough such measurable particles to a location in Australia and Germany and you have almost ping-free communication.
As I so far understood, the measuring of the change of a particle is already reliably possible, which to me sounds like a very usable binary transmission option.
Thanks for any answers. :)
My cat inevitably asks to get out of the house for the night, every evening.
He can choose to go through the front door or the back door, at even odds on average.
If I am the one to open that door, I know which door he exited from.
If my wife opens that door for the cat while I am not looking, I don't know which door.
However I can infer a posteriori which door he exited from, by the inevitable hissing from other cats who live in other backyards: hissing means back door, whereas absence of hissing means front door.
In keeping with quantum mechanics, my wife actually opens both doors at half density of probability, and half of my cat exits through each door.
Not knowing which door my cat "really" exited through yet, I remain coherent in my ignorance. I continue observing a reality which is consistent with my cat having exited both doors half-densely.
Then, half of me would hear the hissing from other cats, and half of me wouldn't.
And because of causality neither half would realize that the other half exists too and has reached a different conclusion.
This is the true nature of decoherence: further entanglement of the Observer.
Now, let's consider twin cats, indistinguishable from each other, but radically different in their preference of front and back door for getting to their nightly activities.
I take one of these cats on a long space trip, not knowing which cat it is.
The other stays home with my wife.
Again, quantum mechanics teach us that I actually have a fNorD mixed cat with me: half front-door-liking, and half back-door-liking.
And so does my wife back home: she too is coherent with that fortunate superposition of cats.
Evening come, the cat back home asks to get out, half-densely, through both doors. My wife becomes entangled with both choices.
Half of her opened the front door, and is entirely coherent with that being a singular fact ; and the other half of her opened the back door, and is entirely coherent with this being the only reality perceivable.
Meanwhile, on my distant spaceship, I read the NFC tag implanted in the cat, and thus become entangled with each half of my local cat.
I'm now half coherent with my cat being the front-door-liking one, and half coherent with him being the back-door-liking cat.
And each half of me is oh so certain that there is no other cat riding along, but the one each half observed.
When I transmit my result home to my wife so she can compare with her own results, regardless of

Entanglement of particles can manufactured in a lab. But is this something seen in nature? Is there a place it is theorized to occur?
I've tried googling but couldn't quite find the same thing.

To begin, what the hell even is the flavor of regular Coke? Sugar? It's indiscernible and, frankly, a little bland. All you really get with the base flavor is fizz.
With the vanilla flavor, however, the whole soda gets creamier, smoother, with a flavor you can notice and a sweet after-taste reminiscent of buttercream frosting. The whole drink gets less harsh to swallow, not to mention that vanilla and whatever the base flavor is work. Like, really well.
In fact, they work together so well that the combination could be it's own soda, because it has it's own taste, unlike cherry or orange Coke (which just taste like regular Coke with fruits shoved in them).
The only real downfall to vanilla Coke is that it's not wide-spread; only two stores in my town sell it, which is a huge shame considering how much of a blessing vanilla Coke is.
Thank you all for coming to my TedTalk. Now go buy some vanilla Coke.
