Cheers. Glad it's hitting the mark.

Great stuffas always. The visualization helped me "see" the experiment, but I don't understand it any better. ☹️ The polarized lens thing always looks like a magic trick.😁

Ta :) Shame it didn't help though. Do you feel that you don't understand or is it more that it doesn't make sense - because you'd be right... it doesn't make sense! ;) It might be better for you to avoid the metaphor side of things entirely, though it does seem common for teachers to use the metaphor so as to not confuse the underlying empirical results, since the 3 Boxes Experiment can actually represent a few different experiments (e.g. the phasor paradox) that each reflect the same superposition results. Here's a decent MIT lecture that goes through the same idea a little slower... kzbin.info/www/bejne/oouWk4OLgNRosMU Might clarify a few little points i glossed over 🤔

@@InfiniteNow_withSeanCrowley qued the video I'll check it out later. Found a video where he does the polarization with light and then with microwaves, that I thought was helpful untill I read the comments where a number of people seemed to think it wasa swing and miss. ☹️

@@fhoniemcphonsen8987 I'm currently reading 'The Dance Of Photons' by Anton Zeilinger, who's a nobel winning physicist. Very easy read, but these topics are very much his domain. He writes it from the perspective of a student, so you sit in lectures, do experiments and so on. It can be a little too simple at times (maybe that's my taste), but simple can often be the best with this stuff. but if you have any questions let me know. I may be able to help 😬👍

@@InfiniteNow_withSeanCrowley I think the issue was I was getting hung up on the actual experiment behind the analogy

Yeah, that always gets me too. The overall point is just to give you a feel for the superpositions because they apply to many experiments. But the actual experiment that this one is trying to emulate is the Stern-Gerlach experiment. The binary question in that case would be whether a silver atom has an electron with spin up or spin down (Similar to the photon polarisation experiment). If the system was classical, the spin should be randomly spread, appearing evenly across the middle of the measurement plate - but because it’s only ever up or down, we know that the electron’s spin is quantised. This gives us the black/white equivalent. Then, if we have a second measurement with the magnetic measurement oriented along a different axis, we can get the angular momentum along that axis. This is our hard/soft question. From there, the rest of what I say in the vid is the same regarding the odd results. But this sort of thing is also what Bell’s theorem tells us, that it’s in a superposition rather than just a classical hidden variable. I’ll share another lecture with you that says much the same thing but doesn’t shy away from using technical terms. But if you don’t understand the terms, push through because there will be enough that you will have picked up from my video that will get you through, and then you’ll see something a bit closer to the actual experiment. 👍
