    Well! This video is disturbing and I am not sure of its context. If Feynman meant in this video Bell's theorem or inequality for which John bell showed that quantum mechanics is incompatiable with hidden variable then I am not sure what Feynman meant by saying "quantum mechanics is the same before and after Bell's theorem" because that is quite wrong. Before Bell gave his argument, people like Einstein suggested in their EPR paradox paper that quantum mechanics is incomplete and we should complete it by adding hidden variables, so before Bell there was a possibility of local hidden variable theories and after him we faced the demise of them since experiments suggest that his inequalities are widely violated. This is actually the work done by Clauser, aspect, and Zeilinger for which they got the 2022 nobel prize. This is actually a huge advancement in the measurement problem since many interpretations seems unfalsifiable like many worlds interpretation. Probably Feynman was on the side that if a theory works, then be happy with it even if it is meaningless. This is what we call "shut up and calculate". In summary, sure Bell did not contribute to our ability to do quantum mechanics but he contributed to the meaning of quantum mechanics.

      Going to marriage counselling might inform you about the nature of your spouse, but it doesn't change the nature of your spouse. What Feynman is saying here is that after a joint session on the couch, you are still married to the same person. It might be revelational if you were blind, but it is not of itself transformational.

    Yeah, "a more precise statement of something we already knew" doesn't really seem accurate. Bell's theorem proves against local hidden variable theories of entanglement, which even Einstein did "know" the answer to, see EPR paradox.

    This is a pretty stupid statement, surprised.

    is this for real or a deep fake?

    Wow, I'm not a huge fan of Feynman and in this, he totally disses Bell and his idea. That's why I have trouble listening to any of his lectures. Maybe he was brilliant but his communication style is a big turn-off.

      Language is complex, and Feynman knew it wasn't so easy to interface. I think he was just using a specific example for the Asker. The Asker "Whats the big deal about Bell's Theorem", and Feynman basically says. "Its a label for something we've already seen, and something we've already been working with. It just provides a proof of it, via these numbers over here". Though, I do agree he subtly disses it near the end. "It does not really stand as a big deal". Which, to his credit, it wasn't really a focus then outside of Bohr and Einstein's famous debate on it. Everyone was just too focused on putting all the work into QED / the quanta in general.
      Bell's Theorem, by the community at large, wasn't taken seriously / valued until later. There are plenty of geniuses that dismissed the concepts at the base of what Bell's Theorem states, including Einstein. So I think Feynman gets a pass here. He can be a bit full of himself in presentation though. Which I'm not a big fan of.

      From my understandings
      (confirmed with observation)there absolutely is a hidden variable.Quantum physics/mechanics information is 25% accurate information in truth confused into something else that brings with it a additional 75% of pure bullshit that appears to be a strategic assault on the attempt to control all information permanently..it's most powerful attack if we fall for it? And why wouldn't we ? We fallen for even more ridiculous notions already.so much more ridiculous infact , that it suggests there is no limit to what we are capable of convincing ourselves of as true.reverse pinhole, bells theorem, arago spot ,vortices and toroidal vortices of light ,double slit.Basically, they are random natural effects ..some poorly represented with solutions in our understandings.. the ones they just except as natural unknown effects are well represented and the understanding is clear.. the ones they attempt to claim as understood are not...
      This is the truth.. lastly , experiments in the nature of light cannot accurately be done in a lab..need natural light and all its "hidden variables".bunch of fkn doorknobs..I have acheived omega and it's offered photomolecular effects on natures full table of contents offers a type of super clusters of structured vapor that condenses into eternally structured water (unless corrupted by humanity) that offers a 3rd complete strand of d.n.a which is protected from all wavelenghts of natural light..(/micro/u.v./x-rays/gamma.etc) as well as increases our electric potential to multiple harmonic potential which offers superconducting properties and extended life spans..gold seeded lithium niobate , selenium, luminol and others ..a type of sea water oil (if you will?)
      Better known as the "elixir of immortality"..
      I have all the details I won't share on this platform ..if you didn't understand or I'm not making any sense or you don't have any money? I am the doorknob and just go back to sleep and forget this ever happened..🤫

      Feynman wasn't brilliant... unless a shinny doorknob..plato once said " time is the moving image of eternity" they thought he was being poetic and metaphorical when infact their information was cataloging truth to the best of their knowledge as plato actually fkn observed that image...it's what I suspected as he is being very literal .not poetic at all.. as precise and specific as possible.. it took me months to solve what that image must of been.. then I figured it all out and all the truth of reality just fell into my lap in a complete totality of sensible confirmable and observable truth.. leaving it indisputable .that I encourage any to try.. it will educate and solidify its validity a little more.. best part of all this is that I'm not even a genius or anything.. just a totally normal working family man.why good creativity.. it's a requirement if you like to solve the nature of creation..(which seems I have?)..all the mysyeries my understandings haven't solved is because their details I haven't reviewed yet..but once reviewed are no longer mysteries of reality..there is only two ways of creating a mystery. If you dont know? It's a mystery but also if you beleive something that is a error, you have just created a mystery in a unrelated field that infact related in a way you would never think to look as no one goes looking for answers they beleive to already own. Leaving the mystery locked away In plain sight for a bunch of doorknobs to defend as something else...this is all truth and lay down all my credibility as wager..I dont treat information lightly as I won't speak if I don't know.. false news is a disease and I wouldn't ever wish to endorse.. the fact that I say this should be found most concerning in respect to its validity..
