You could argue it's not really like a wormhole since nothing physical is moving (energy is a property of matter, it is not itself physical). And that it is FTL because even though the thing being transferred is non-physical it is still in some sense transferring from one place to another faster than light. But the laws of physics conspire in such a way that you can't send a message using entanglement. Which perhaps makes sense as faster-than-light messaging would appear to enable sending messages back in time, which opens a huge can of worms 😀

Yes my intuition was "input 1 in one of the particle" (change it's state in a expected way) to observe the behaviour of the other entangled particle. But as you state that, influencing the state of the particle will break entanglement.

But, from there, how are we sure the particles are entangled if we can't act on any of them and reflect a resulting change in the other particle.

I guess we can observe both particles surrounding environment and see that there are similitudes ?

Anyway thank you for your time helping me understand :)

How can I prepare laptops to be recycled, especially if I don't have the passwords to use them?

My family has several old laptops that we want to dispose of through the state's official electronics recycling program. But we can no longer log in to those laptops, and I'm concerned that they may contain sensitive info (passwords, finances, etc.) that a savvy person could access.

Is it safe to recycle them as is? Should I try to take out the hard drives? (If so, would I smash them with a hammer or run a powerful magnet over them or something like that before disposing of them?) Thanks.

? this whole discussion is about apple watches and their glucose monitor. The "airpods" mention was a portable charger station for replacable watch battery modules, the same way you chuck your airpods in the case to charge during the day.

The information you send over a wire doesn't change the entangled particles in any way (or do you mean sending a 1 using the entangled pair? That's not possible, the entanglement breaks). What does change the particles is any attempt to measure or change the particle's properties. (With regard to OPs article I believe they are measuring the environment around the particle, not the particle itself, in order to maintain the entanglement.)

You seem to be complaining about the quality and cost of healthcare. Unfortunately you can't have both.

I understand that you don't want people to choose between bankruptcy and death but that doesn't make universal healthcare a good idea. It will solve some problems and cause others. It's a really complicated issue and having seen what public healthcare looks like in a wealthy country I get the impression that privatisation is the way to go. You seem to have the opposite impression. To me this just shows that both systems suck and completely overhauling something which sucks for something else that sucks may not be wise.

Do I look like I'm made out of money?!

>why does it always has to be online

Because online has unlimited content so the child will theoretically keep playing forever.

>Kids are not better in school today or social behavior.

As a former teacher I can tell you that, while it does significantly reduce their attention span to a worrying degree, the main culprit of asshole kids are narcissistic and/or enabling parents that neglect/smother their kids to a point where discipline is impossible.

In my entire career I've had maybe 2 kids whose behavior didn't match the parents care and in both those cases some form of mental illness was involved.

> So why keep letting kids be online all the time.

Online is just a faster, more accessible version of the Mall's ball pit playground.

It works in nearly every 1st world country besides the US. I don’t believe people should have to choose between going bankrupt or saving their loved one by treating cancer. We certainly don’t get what we pay for in the US. We pay the highest cost for pharmaceuticals in the world. They’re no better than what you can buy in Canada or Mexico for pennies on the dollar. My insurance premiums and all of the working people’s keep going up, but my healthcare has gotten worse. I have to make appointments weeks to months ahead of time and once I am seen I’m shuffled along so they can hurry to the next patient. They have stats they have to meet too which don’t have anything to do with making people better. I could go on and on. Most of us in America are not getting any better healthcare and definitely not getting what billionaires get. And it’s not like that business will go away. Billionaires will still pay doctors privately to get their luxury healthcare. Meanwhile the rest of us are paying to increase wealth for shareholders for increasingly less time with our healthcare professionals.
