    “observing changes the result” doesn’t mean conciousness attempting to look at it changes the result, there is nothing special about conciousness (in quantum mechanics)

    “observing changes the result” means we try to measure atoms and fields but unfortunately our measurement tools are also made out of atoms and fields which interact with the atoms and fields we are trying to measure, giving us a different result than if we don’t attempt to measure it

    It does bring up interesting questions about what the “real” behavior of reality is tho, since anything we observe is technically different than what it would be if left alone. We can only ever know what a slightly altered state of reality is

      Think of it like this:

      You can use a tennis ball machine to measure how far away a house is by firing the tennis ball at a constant velocity, timing how long it takes the tennis ball to come back to you, multiplying that time by the velocity, and dividing by 2 (since you measured the distance for a round trip). This works pretty darn well for measuring the distance to houses.

      But now try this same trick to measure the distance to another ball. When your measuring ball hits the ball you want to measure, it doesn’t stay resolutely planted in the ground like that nice friendly house. The energy from your measuring ball bounces the ball being measured off into the distance. Even if you could get your measuring ball to return, the ball you measured isn’t in the place you measured it.

      Replace that tennis ball with a photon, and you have the basic picture. There’s no such thing as passive observation. Measuring something interacts with that thing. Conventional measurement is like in the case with the house, the thing being measured is so much bigger and more stable than the thing we’re measuring with that the effect is negligible. But once you start trying to measure something on the same scale as your measuring tool, the ensuing chaos makes it basically impossible to get useful measurements.

      Not quite - observability in quantum mechanics is about the event producing an interaction that could potentially be measured, regardless of whether we actually attempt to measure it. By interacting with other things the superposition is collapsed and we can determine it’s current properties, but it’s still the “real” behaviour of things, because we can only determine things behaviours from their interactions with other things - not knowing what they do when left alone isn’t just about there not being a human around to interacts with them, but about there not being any other particles - no atoms, no electrons, no quarks - for them to interact with either.

    This always bugs me. Quantum Mechanics isn’t actually that difficult. It has some nasty maths, yes, but that’s mostly slog work, rather than an impossibility. 90% of it is the Schroedinger’s equation + boundary conditions.

    The main issue is that you have to abandon the particle model of reality. This is deeply engrained into our brains. If you try and understand it as “Particles + extras”, you will fail. You have to think of it as “Waves + extras”. It then, suddenly makes logical sense.

    It does have some interesting implications, however, about deeper reality however. E.g. what exactly IS decoherence, from a physical point of view. Also, what is physically happening, dimensionally, when a wave is complex, or even pure imaginary. These are beyond the scope of QM however.

      The big problem isn’t that the math is hard, or that’s often impossible to visualise. The problem is that a whole bunch of charlatans intentionally misinterpret what “observing” is in QM, to make money off of gullible victims.

      To elaborate on this, the Schrödinger equation, which describes the dynamics of a single particle, is a wave equation and hence a lot of classical intuition from e.g. electrodynamics can be applied. It is many-body systems, i.e. systems composed of many interacting particles, which is not only mathematically complex but can also defy classical expectations due to emerging phenomena, etc.

        I believe the more nuanced argument is that even though you think you have free will and are making choices such as “let’s build a hospital” or “I will write a song”, due to the nature of all effects needing causes, in a chain - there is no such thing as free will as there is no cause without effect.

        That second one… Isn’t that manifestation? Hard agree with you there, usually people promoting manifestation are simultaneously saying “you can imagine anything and make it real” and in the same breath are trying to sell you something that you evidently aren’t able to imagine into your reality for free.

        On the other side, technically, even breathing is enough to satisfy the goal of “changing the universe”. That bunch of molecules would not be moving through the universe like that if it weren’t for your consciousness (but few appreciate sentience at that atomic of a mechanical level lol. I just think it’s a massive glazed over step in going from mind to city/culture/science)

          A byproduct of self help hokum. Most people who have difficulties in life relating to their “success” are told to visualize their goals, and magically they’ll achieve themselves somehow. They never actually say how to summon the executive function necessary in order to perform the tasks to achieve the goals. That would result in too many middle class people.

          https://en.wikipedia.org/wiki/Law_of_attraction_(New_Thought)

          I think this can be interpreted in different ways. One can be that we sort of go in the direction we’re looking, and there’s evidence to back that up. You don’t just magically become a nuclear scientist just like you don’t magically become an actor. It usually takes years of dedication and focus.

          Another is that if we just ‘will’ it into being, then it will be so. I don’t think this is really accurate of reality.

            I mean, I’m coming from a background sceptical of the law of attraction because it’s just repackaging having goals to sell self help books. How do you become a nuclear scientist? Step 1) step 2) step 3) etc.

            The law of attraction is new speak used to sell known principles to people, in my opinion. Manifestation, in my opinion, is the same thing but coming at it from a crystals vibe rather than the self help vibe of the law of attraction.

            I don’t mean to be a jerk about it, hence all the in my opinions, but as I said, I am very skeptical of the usage and utilization of the concept of manifestation.

            All that said, you’re not wrong. The principle is valid and it does work, but it’s mustering the discipline to stick to those goals, that’s the secret that everyone is looking for. Idk I feel like I’m starting to ramble, do you have any points/counter points to any of this?

              Absolutely, I totally agree with you.

    Sean Carroll had a great take: everything is waves in fields and we know of five fields: Strong Weak Electric Gravity Higgs

    Particle behavior arises from interacting waves. So anything that acts like a particle is actually waves interfering with each other.

      The term they should have used from the get-go is “measurement” instead of “observation”. Humans will always tack on mystical mumbo jumbo if given a chance, muddying up the waters for us laymen trying to learn, and “measurement” sounds much more neutral to me.

        Continental philosophy is so named because the Brits referred to the philosophers in continental Europe thus. The opposing school is more generally known as analytical philosophy, and posits that rigorous logic can be applied to philosophy.

        Continental philosophy: “love should be a dimension, just like time, that would be awesome.”

        Analytical philosophy: “I’ll buy you a beer if you can prove to me that the electron exists.”

            Sort of. Continental philosophy is great if you’re a stoner, a hopeless romantic, have preconceived religious notions that your philosophy must have a carve out for, or if you write for Hollywood.

            Sometimes you get all four. See for example, the “totally scientifically plausible movie, Interstellar!” which posits that love permits time travel… Which this meme format would work great for ;)

    IMO, the perceived inscrutability of quantum mechanics is mostly the result of the dominance of the “shut up and calculate” approach to the question of interpretation.

    Don’t get me wrong, I understand why focusing on the math and ignoring the rest is a good approach to have when you’re actually doing practical scientific work in the field. But if you’re wanting quantum physics to “make sense”, then you’re asking about what it actually says about the underlying reality, and that’s a question that requires thinking about interpretations of QM.

    Once you start thinking about it in terms of a particular interpretation (or category of interpretation), then QM makes as much sense as any other high level physical theory (certainly no worse than general relativity.)

      The various interpretations help in processing the math, but isn’t the same as understanding - there are a bunch of fundamental facts about quantum mechanics that we just don’t understand, even though we know the elements exist, that they happen, and even how we can take advantage of them.

      The difference between quantum mechanics and other high level theories like relativity is actually quite large, because the higher level interactions all derive from quantum level states and interactions. At the point where question marks really start popping up (weak and strong nuclear forces, gravity, dark matter &/ energy) it’s almost always a matter of quantum mechanics getting involved and being weird.

      My quantum mechanics professor started our first lecture with “if you think you understand quantum mechanics you do not understand quantum mechanics”, because there are still some really big question marks around our understanding of it. Especially what in the fuck spin actually is.

        In the same sense that the territory helps in processing the map, I suppose.

        but isn’t the same as understanding - there are a bunch of fundamental facts about quantum mechanics that we just don’t understand, even though we know the elements exist, that they happen, and even how we can take advantage of them.

        I’m not sure what you mean here; discussions of interpretation are literally about understanding these facts.

        The difference between quantum mechanics and other high level theories like relativity is actually quite large, because the higher level interactions all derive from quantum level states and interactions. At the point where question marks really start popping up (weak and strong nuclear forces, gravity, dark matter &/ energy) it’s almost always a matter of quantum mechanics getting involved and being weird.

        Going to have to disagree with you here, relativity, both special and general, get just as weird without any need to invoke quantum physics. And they’re not the only one. The only difference is that we have a general consensus on how to interpret them, which we don’t with QM.

        My quantum mechanics professor started our first lecture with “if you think you understand quantum mechanics you do not understand quantum mechanics”, because there are still some really big question marks around our understanding of it. Especially what in the fuck spin actually is.

        I think this is equivocating a bit; there is a difference between the things we don’t understand about quantum physics, and the things we just straight up don’t know. I think it’s possible to understand quantum physics, with the caveat that understanding means recognizing that there are things about it that we simply do not know.

      I think a degree of shut up and calculate is needed, at least in the beginning. Without a solid math based understanding of the fundamentals, trying to prognosticate on the ‘meaning’ of it is inevitably going to fall into pop-sci style stuff.

        I’m not so sure. I think a degree of shut up and calculate if you actually want to get a physicists level understanding, a large degree. But I strongly believe that it’s no harder to give a clever layman a working understanding of the underlying concepts, in purely conceptual terms. Honestly, I think the reason the quantum mechanics has been so prone to pop-sci charlatans is that legitimate science communicators keep trying to explain it in interpretation-agnostic terms, which makes it sound far more mystical and paradoxical than it is.

    We have the many-worlds interpretation that makes perfect sense (as long as you accept that consciousness is just a function of the particles in your brain and not some spiritual essence detached from the laws of physics), but Niels Bohr had to convince everyone that Quantum Mechanics is not supposed to make any sense just so that he could win his argument against Albert Einstein, so now everyone think it’s just another interpretation on equal footing with the Copenhagen nonsense.
