    In short

    😐 = Electron if you look

    = Electron if you don’t look

    I think the meme is just poking fun at the physics behind the whole thing, but in case anyone doesn’t know:

    It’s called the observer effect, and it happens because:

    This is often the result of utilizing instruments that, by necessity, alter the state of what they measure in some manner.

    And particularly in the double-slit experiment:

    Physicists have found that observation of quantum phenomena by a detector or an instrument can change the measured results of this experiment.

    So for anyone who wants to have a surface understanding of the observer effect, the wiki does a fair job of the basic explanation.

    It’s really frustrating that people who don’t understand this experiment have insanely taken into assume that a magic particle spell understands if a human being is watching or not.

      Perhaps it would be better to explain why instead of attempting a mic drop based on your superior knowledge?

        I think the issue is that quantum mechanics is hard to popularize without leading people into wrong conclusions, pop science clickbaits make this worse.
        I find it easier to understand if you say that observing necessarily means there’s an interaction energy (for example a photon), otherwise no information can be retrieved, and however small that information retrieval energy is, quantum systems are so sensitive, that it is enough to modify their behavior.

      That’s not really it. You need something that measures the state of the electron. Merely looking in the direction is not enough. It has to be something that interacts with the electron.

      A camera alone isn’t enough. But light (eg photons) with enough energy should be enough. But then that energy will manipulate the electron. If you had a completely dark room and pointed a camera at the experiment it wouldn’t change anything.

      It’s kind of like having your cake and eating it too.

        Yeah, it turns out that slapping the electron around like with a big stick or whatever causes it to change its behavior, go figure! :-P

        So if we didn’t need light to see it then it would continue doing whatever it does?

        I wonder how the universe would look if we didn’t need light to see 🤔

      You need to qualify that statement somehow, or maybe give a citation or source that supports such an idea

          Both these figures are embarrassingly bad.

          Hoffman confuses function for perception and constantly uses arguments demonstrating things can interpret reality incorrectly (which is purely a question of function) in order to argue they cannot perceive reality “as it is.,” which is a huge non-sequitur. He keeps going around promoting his “theorem” which supposedly “proves” this yet if you read his book where he explains his theorem it is again clearly about function as his theorem only shows that limitations in cognitive and sensory capabilities can lead something to interpret reality incorrectly yet he draws a wild conclusion which he never justifies that this means they do not perceive reality “as it is” at all.

          Kastrup is also just incredibly boring because he never reads books so he is convinced the only two philosophical schools in the universe are his personal idealism and metaphysical realism, which the latter he constantly incorrectly calls “materialism” when not all materialist schools of thought are even metaphysically realist. Unless you are yourself a metaphysical realist, nothing Kastrup has ever written is interesting at all, because he just pretends you don’t exist.

          Metaphysical realism is just a popular worldview in the west that most Laymen tend to naturally take on unwittingly. If you’re a person who has ever read books in your life, then you’d quickly notice that attacking metaphysical realism doesn’t get you to idealism, at best it gets you to metaphysical realism being not a coherent worldview… which that is the only thing I agree with Kastrup with.
