Bell’s Theorem: The Quantum Venn Diagram Paradox – YouTube and Twitter explained with polarised filters
Posted by jpluimers on 2024/12/24
These are cool explanations of Bell’s Theorem:
- [Wayback/Archive] Bell’s Theorem: The Quantum Venn Diagram Paradox – YouTube
- [Wayback/Archive] Santiago Ortiz on Twitter: “I use polarised filters to explain (some) quantum mechanics to my kids. How is it possible that adding a 3rd filter in between (the one at 45º) some light get to go through the otherwise black rectangle in the middle?”
- [Wayback/Archive] Santiago Ortiz on Twitter: “@chevreuil wave function updates when photon goes through filter B (45º), and “erases” the information of previous initial collapse (filter A 0º), so it has now 50% chance of going through filter C (90º) even if previously it already went through A (0º)… crazy”
- [Wayback/Archive] Sartanas on Twitter: “@moebio @chevreuil Wow I didn’t knew the wave function could “uncollapse”. So that means the photon can reset their polarization? Why doesn’t that happen after each filter though?”
- [Wayback/Archive] Santiago Ortiz on Twitter: “@Sartanas @chevreuil It resets when it collapses. But language is tricky, in reality it never has a polarity, but a superposition of polarities… until it collapses and creates certainty in one dimension and superposition in the independent dimension.”
- [Wayback/Archive] AlliesBeautifyingNonstopHolisticGender on Twitter: “@moebio @Sartanas @chevreuil so does order matter? 0°+90°+45° ≠ 0° +45°+90°? reset implies t has changed but the superposition is just uncancelling them out .. the intuition always feels lacking for this example. show me to polar math of them canceling out i guess.idk”
- [Wayback/Archive] flowdor on Twitter: “@AllieMarbar @moebio @Sartanas @chevreuil Apparently:”
- [Wayback/Archive] farintothestars on Twitter: “@flowdor @AllieMarbar @moebio @Sartanas @chevreuil can someone explain this to me like im stupid & in a field not remotely close to STEM 💀”
- [Wayback/Archive] Linda Cardellini Updates 💃 on Twitter: “@farintothestars @flowdor @AllieMarbar @moebio @Sartanas @chevreuil Photons do not have memory.”
- [Wayback/Archive] saua on Twitter: “@farintothestars @flowdor @AllieMarbar @moebio @Sartanas @chevreuil Even WITH that background, the explanation is very un-intuitive. Unfortunately I don’t know any better explanations than this video (which isn’t ideal without any STEM background):

- [Wayback/Archive] Bonnie Lawrence on Twitter: “@moebio @chevreuil Cool! Why 50%?”
- [Wayback/Archive] Santiago Ortiz on Twitter: “@BonnieMLawrence @chevreuil because a photon that passed the 45º test, is completely free to decide whether it goes through 90º, because 45º doesn’t say anything (is independent) from 90º. You can’t have information about two independent axis, that’s the Uncertainty Principle for you!”
- [Wayback/Archive] elbalalaw on Twitter: “@moebio @chevreuil I have two questions : How can going through a filter erase the information of the wave function ? Also isn’t drakness the absence of light ? If the combination of filters A and B produces darkness shouldn’t that mean that ther are no light waves passing through ?”
- [Wayback/Archive] michael on Twitter: “@elbalalaw @moebio @chevreuil Yes, light can not go through filter A and then B. However, if you put filter C in between them, some light gets through! Classically you would think that adding more filters should make it darker, but polarization/quantum mechanics is weird”
- [Wayback/Archive] 𒇷 𒁯𒅗 🇺🇦 on Twitter: “@moebio @chevreuil The only way I can think of it without going insane is the photon leaves its source and arrives at its destination at the same time (e.g. no time). Every probability event along its path is realized. With enough photons, you have a very accurate measure of central tendency.”
- [Wayback/Archive] (3waves+Δ+Ο+Ο.2+Deltomicron+BA.2/4/5) Survivor on Twitter: “@Lee__Drake @moebio @chevreuil Exactly. A ‘photon’ is the instantaneous change in time-value, which we perceive as ‘journey-through-space’. There is only time. And it ticks asymmetrically, creating the universe entities, because its ‘nanoseconds’ are prime numbers.”
