That’s right. Not only it’s an analogy, it is also a bad one and completely misleading, at least according to physics of the last 50 years. Note how the article frets about the loss of locality.
The problem with that analogy is it gives an illusion of understanding while being completely misleading about what Bell’s inequality actually tells us about nature.
The whole point of Bell’s inequality is that quantum entanglement is fundamentally different than classical correlation between two objects which have some opposite properties the observer simply does not know about before observing one of them.
It’s not helpful to use an analogy which teaches the reader the exact opposite of the point you are trying to make.
Your example with decaying atoms suffers from the same misunderstanding. Quantum entanglement is not about lack of information about some specific states, if that was the case, why would anyone talk about loss of locality?
Understanding entanglement and Bell’s inequality requires a completely different ontology than your everyday experience with classical objects. I highly recommend the video I linked above for an approachable explanation. It is not as simple as these analogies but at least it gets to the actual point of this result which tells us something profound about how nature works.
That’s not quite correct. There are no good analogies between classical objects like marbles or socks and entanglement.
In fact, Bell’s inequality was stated as a collaboration game that can only succeed if you use entangled particles. No classical object will get you the same results.
You still can’t communicate faster than light but the reason is more subtle. The article does a good job but for a deeper explanation I’d refer to Sean Carrol: https://youtu.be/yZ1KSJbJAng
TL;DR Had anxiety. Discovered breathwork. Learned to code and built a free app with no user data collection.
Like for many people, the lockdown was doing real a number on my anxiety. I was lucky to discover breathwork through J. Nestor’s excellent ‘Breath’. Couple more books and podcasts later, I decided to build a simple, privacy-first app around some of the key exercises that affect wakefulness, focus and sleep.
I’m 34 and I had to learn programming from scratch. It’s been a great learning experience to say the least. I would appreciate any advice or feedback on the app or how to become a better app developer.
