    A measurement causes collapse though.Cartuna

    In collapse interpretations only.

    This should cause EM radiation, which isn't observed in a double slit experiment with electrons, like there is no electric moment observed for s-orbitals in atoms.Cartuna

    No, it shouldn't cause EM radiation. Collapse simply changes the state amplitudes. You're back to thinking that physical properties themselves are somehow split. When collapse takes you from a*E1 + b*E2, for instance, there's no transition from E2 to E1. That wouldn't be collapse, that would be a process.

    The medium in which the particle flows represents the wavefunction which litterally makes the Brownian move erratically and seemingly randomly.Cartuna

    There's no randomness in Bohm, that's the point. There's _chaotic_ behaviour: which trajectory the pilot wave forces the particle is extremely sensitive to small, hidden differences in initial state, but is deterministic.

    An electron in an s-orbital has no angular momentum, and to associate spin with a continuous flow of current flies in the face of all modern conceptions of spin.Cartuna

    That's precisely where the magnetic moment of a charged particle comes from.

    There's systems more fundamental than conscious systems. Consciousness only occurs in biological systems. One would expect therefore that a complete theory of biology would be more fundamental than any particular theory of consciousness, though one would also expect the latter to be easier to create models from.

  • Double Slit Experiment.
    There is just no scientific evidence the orthodox view is the correct one.Cartuna

    Obviously there is, since consensus in science is built around evidence. Where there is no evidence, there is no orthodoxy. The correct interpretation of QM is still up for grabs, but that doesn't mean that any theory is as good as any other. One example is that God selects outcomes of quantum events.

    The ground state of hydrogen has no electric moment (maybe if you could shake the proton, which would imply that the state is not a groundstate anymore though, like shaking the electron), but even if it had this would not constitute evidence.Cartuna

    That is the evidence, since in hidden variables theories like Bohmian mechanics, it _should_ have a dipole moment: two charges separated by space makes a dipole.

    I already mentioned this. If an electron hops erratically like a Brownian particle, you would expect an EM field to come out of the wavefunction.Cartuna

    An EM field exists whether it's static or moving. That's what charge ensures. Where do you get this stuff? Hearing Brownian motion come up makes me think you're just grabbing at physics concepts at random in order to keep speaking for the sake of speaking.

    But there ia no continuous flow of current.Cartuna

    Orbital angular momentum? Spin?
  • Double Slit Experiment.
    In Bohmian mechanics, in the ground state of hydrogen, the electron is at rest relative to the proton.SolarWind

    That's untrue even in Bohmian mechanics. The electron is still moving, the relevant point is there should be a time-dependent electric dipole from the two separated charges.

    However, the electric dipole is not measurable, since any approach of an electric charge immediately sets the electron in motion.SolarWind

    You don't need to displace anything. Emitted radiation, for instance, tells you what the dipole moment is. Anyway, Bohm himself conceded that the charge distribution would have to belong to the pilot wave, not the particle, which is tantamount to giving up on the idea of point particles (charge being the most important particle property of electrons).

    The second person had knocked him to the ground, beating him in the neck with a skateboard and was wrestling his gun away when shot.Hanover

    He was trying to get R's gun off him after R had just threatened a crowd and shot a man, yes. R's defense was that he felt, if his gun was seized, he'd be shot with it. The judge had instructed the jury to consider only R's described perspective, and not whether R had good reason to believe that his assailant had good reason to disarm him.
  • Rittenhouse verdict
    Then R must be color blind because all three people he shot were white. What evidence do you have for this claim? Someone with a "D" next to their name told you?Harry Hindu

    That he took a machine gun to a protest against police murdering black people? That the group he approached with said gun was largely black? That said, I did cause a mispeak in my edit. I originally wrote "shoot people". So to clarify, he "did shoot people".

    Stupid. People that think there is an active shooter typically run from the scene, not towards the active shooter. What did he expect to accomplish running at a man with a gun, if not to get shot?Harry Hindu

    And they chased him even after he proved his willingness to murder people by stopping his retreat to shoot Rosenbaum. Stupid, right, if self-preservation should override concerns about an armed murderer running about crowded streets. But maybe, just maybe Harry, these people are better than you and would risk their lives to try and disarm a murderous lunatic with a machine gun.

    Do you mean I have to stop questioning the orthodoxy?Cartuna

    No, you're not scientifically unorthodox, you're ascientific: your beliefs concerning nature are not impinged by scientific facts.

    There is no scientific evidence for the orthodoxy. I defend a hidden variables view.Cartuna

    I've already given an example: the electric moment of ground state hydrogen.

    what does it mean in that context? That I have a chance of ending up in following parallel worlds? Which makes it still hard to believe though that mass is conserved, but you can distribute it nicely.Cartuna

    I'm not sure you quite grasp MWI, or superposed states generally. Even if no branching occurs, and a particle's superposition of being here or there remains coherent, it still has a mass. You don't need branching or collapse to encounter issues like superposition.
  • Rittenhouse verdict
    The witness admitted he was shot in self defence. That is basically the same as saying (in that instance) he wasn’t guilty. I didn’t mean to imply he said anything about his guilt regarding the deaths.I like sushi

    But you did say that. And, no, the paramedic did not say he was shot in self-defence. He said he had a gun pointed at Rittenhouse and thought Rittenhouse was an active shooter. Which of course he was.

    It was a pretty clear cut caseI like sushi

    It was a very clear cut case. Rittenhouse went to Kenosha to shoot black people, did so, but was acquitted by a jury instructed to ignore anything Rittenhouse did to cause concern to others.

    This cognitive dissonance was imposed by the judge. By instructing the jury to only factor in R's testimony as to his own headspace, there was no room for logic, or rather no means by which a breach of logic could be a barrier to an unjust acquittal. The jurors were forbidden from considering the fact that R's second victim had more reason to suspect R -- who had a gun -- would shoot him in cold blood than that [EDIT] second victim -- who had no gun -- would shoot R. The armed R didn't even need to feel threatened by his unarmed victim (i.e. the jury did not need to make sense of that), he merely had to claim that he did. Since nothing but his claims could be considered, the judge ensured a prejudiced jury, and an inevitable miscarriage of justice.

    The defense is obviously preposterous. Consider a terrorist being acquitted with the defense: "I detonated the bomb I planted in the building, but only because I was worried they'd find it and blow my house up with it." Stupid, no? But exactly the same kind of stupid as: "Yes, I shot an unarmed man, but only because I was worried he'd take the gun I brought to threaten him with off me and shoot me with it."

    A partìcle can be in all places it likes. But not at the same time. Call it a fundamental belief.Cartuna

    I did, because it is. You're not making an argument here, you're just reasserting outdated beliefs. There's nothing more here than someone insisting that evolution is untrue because God made everything.

    Science is driven by observation, and observations (such as the double slit experiment) do not favour your beliefs. Bohmian mechanics doesn't solve your problem either, since Bohm was obliged to move particle properties from the particle to the pilot wave to explain experimental outcomes (such as the zero electric moment of ground state hydrogen), and because the pilot wave itself is a field, i.e. a thing that's already in multiple places at once.

    What we learned from Bohm was not that particles are points, but that we should keep an open mind.

    But it still assigns probabilities to branching points.Cartuna

    It assigns branch widths according to the Born rule.
  • Double Slit Experiment.
    How can a particle be at several places at the same time and how can it be pure chance (whatever that means without a deterministic substrate) that determines?Cartuna

    The fundamental belief here being that a particle cannot be in more than one place. Remove the belief and the question vanishes. All that remains is to falsify or verify that belief.

    MWI doesn't say it's pure chance. Chance plays a role only in QM interpretations with collapse mechanisms.
  • Rittenhouse verdict
    Try watching large portions of the actual trial. He was clearly not guilty and the guy he shot (who didn’t die) also said so.I like sushi

    Yes. Like.Cartuna

    It would look like Bohmian mechanics because it is Bohmian mechanics, developed by Bohm and Dirac.
  • Double Slit Experiment.
    My point is that the the MWI is caused by the wavefunction being seen as a mathematical entity.Cartuna

    That's not right. The wavefunction is a mathematical entity. MWI came from taking that entity as a literal description of the universe.

    If it was decided back then to start a search for a deeper theory, which de Broglie proposed more or less (by means of physical pilot waves), who knows what the theory would have looked like these days?Cartuna

    It would look like Bohmian mechanics.

  • This is the title of a discussion about self-reference


    So something like G = g + g S G is recursive, because you can take the whole RHS and substitute into the G on right:

    G = g + g S G
    = g + g S ( g + g S G )
    = ...

    ad infinitum.

    Whereas something like

    du(t)/dt = u(t)

    has to be solved iteratively, but isn't expandable recursively as above. Something like that may have exact solutions, whereas G has to be solved as a power series and terminated arbitrarily.
