  • Quantum Entanglement is Holistic?
    I certainly don't understand why an attempt to create an image of a "physical" object would require the inclusion of a completely unrelated image. Which part of the published picture are we supposed to identify with the entangled wavefunctions? Even if the swirling dots are supposed to be entwined photons, what scientific meaning are we supposed to learn from the image? An artist could have done the same with much less technological tomfoolery. Were the scientists themselves "gullible new-agers" trying to send a message to blind black-&-whiters?Gnomon

    Here's a figure from the article from which you've clipped your yin/yang symbol. It shows the black and white input image and the colored output. Note the size, measured as 4mm, or about 1/4 inch. This does not show entangled photons, it shows the recreation of an image.

  • Bell's Theorem
    " **2 " means raised to the second power (i.e. squared). So " **3 " means raised to the third power, etc. This is standard scientific notation.EricH

    I've never seen "**" used as a symbol for the powers functions. I think the standard is "^", e.g. 5^2 = 25. In my experience, computer programs will accept that as input.

    Is it your understanding that the scientists took a picture of a cultural symbol, and published it as-if it's a picture of two photons orbiting each other?*4 If so, was it a joke on gullible New Agers?*5 Or were they deliberately trying to deceive us ignorant Philosophers?Gnomon

    No, you've completely misunderstood. As @punos noted:

    The image used in the experiment is arbitrary, they could have used Mickey Mouse or any other image. I think a Lambda symbol was used in a prior version of the experiment.punos

    They made a bad choice in using the taiji because gullible new-agers could so easily jump to the incorrect conclusion without understanding the substance of the experiment.

    The articles I've seen don't mention that they started with a yin/yang symbol as input.Gnomon

    You're right, the people who wrote the articles either didn't understand just as you didn't or were unaware of possible misinterpretations. Take a look at the original article. The symbol does not play a big role in the results. It is only really discussed in a caption to one of the figures.

    As I noted, it's not a case of reading meaning into a pattern. The yin/yang pattern was intentionally used by the experimenters as part of the experiment.
  • Quantum Entanglement is Holistic?
    The recent publication of a cutting-edge physics experiment revealed that entangled photons returned a holographic image that looks identical to the Yin/Yang symbol of Taoism and Holism. The article was quickly reproduced in other publications, but I was surprised that no one expressed surprise at the irony that a state-of-the-art Western scientific photographic technique produced an image traditionally used to symbolically portray the holistic philosophical worldview of an ancient Eastern philosophy.Gnomon

    After slogging through the original paper (link - https://www.nature.com/articles/s41566-023-01272-3#Fig2) I think I've sort of figured it out. Not certain. If I'm right, you've misunderstood what's really going on. The input to the experiment was the image of the yin/yang symbol. It was disrupted and then recreated using the new holographic/entangled photon technique. Somebody else take a look and see if they think I'm right.

    I don't know why they used that symbol. Seems like a confusing choice given the possibilities for misunderstanding.

    According to the general theory of relativity space without ether is unthinkableflannel jesus

    I used your quote to track down the article - "Ether and the Theory of Relativity" by Albert Einstein. Here's a link:

    https://mathshistory.st-andrews.ac.uk/Extras/Einstein_ether/

    Really great paper taken from a lecture in 1920. I've been looking for something like this for a long time.

    Your quote is taken quite a bit out of context. It is clear the "ether" Einstein is talking about is space or space-time, not a luminous ether which is the supposed medium for the propagation of light. He makes that distinction explicitly.
  • The von Neumann–Wigner interpretation and the Fine Tuning Problem
    I apologize for offering you novel ideas that your background didn't prepare you to understand. But the scientific terminology I used, by analogy, did represent my unconventional meaning. So, it was not intended to mislead.Gnomon

    Bullshit. You've appropriated language that has specific meanings to give your ideas a thin coating of false legitimacy. It's dishonest, no matter what your intentions were. There have been times on the forum when this kind of garbage would not have been tolerated. We lost a lot of our scientific voices - @Streetlight, @TimeLine, and Apokrisis. Apokrisis is still around from time to time.

    No need for defense. I thought I should take the offense against misinformation.

    It's just an analogy.Gnomon

    You know I don't hold much truck with your theories. We've discussed it in the past and there's no need to take it up again. On the other hand, here you use terminology which has a very specific technical meaning which is universally understood by scientists - The Laws of Thermodynamics. But you use the term in a way which is not consistent with the scientific understanding. That's why I commented. You shouldn't appropriate scientific terminology in a way that misrepresents it's meaning.

    You're being a bit disingenuous. The Laughlin quote you provided refers to the quantum vacuum, not the luminiferous aether. Yes, the quantum vacuum is an established fact, but it is not the medium through which light was once thought to propagate.

  • Bell's Theorem
    This is not at all true. The physics of waves is very definite. Waves require a medium. All physicists know this, it is taught in basic high school level physics. This is why light is understood by physicists to exist as particles, photons, not as waves, and the movement of photons is understood by "wave functions", not wavesMetaphysician Undercover

    Clearly there's no reason for you and me to continue this discussion.

    I do have this to say to anyone else reading this post - The fact that light can propagate as a wave through a vacuum with no medium is an established scientific fact. It's part of the foundation of modern physics. In order to reject that, you will have to reject the findings of physics for the past 150 years.
  • The von Neumann–Wigner interpretation and the Fine Tuning Problem
    but "role of observation"*1 and "observer effect"*2 are different in what sense?Gnomon

    From Wikipedia:

    In physics, the observer effect is the disturbance of an observed system by the act of observation.[1][2] This is often the result of utilizing instruments that, by necessity, alter the state of what they measure in some manner. A common example is checking the pressure in an automobile tire, which causes some of the air to escape, thereby changing the pressure to observe it.Wikipedia - The Observer Effect

    As the definition indicates, the observer effect is not a property of quantum systems. It is often used to explain the results of psychological studies when the experimenter interferes with the experimental subjects. In his original paper on the uncertainty principle, Heisenberg identified the observer effect as the cause of uncertainty. Later, it was determined that the phenomenon is caused by properties unique to quantum systems.

  • Bell's Theorem
    It's a statement about what it means to be a "wave", how the concept indicated by that word is understood through normal human conventions, especially as it is used in the more specific physics of waves.

    So, if light exists as a wave, which much evidence indicates, then it exists according to the principles understood by the concept signified by "wave", which i was talking about in the statement. It is a simple conclusion of deductive logic. P1, Waves have x essential properties. P2 Light exists as waves. C Therefore light has X properties.
    Metaphysician Undercover

    Phenomena in the world are not constrained to behave in accordance with our definitions. Before Michelson-Morley, people did believe that a medium was required for a wave to propagate. It took them a while to be convinced otherwise. Your definition is 150 years out of date.

  • Bell's Theorem
    It's not pseudoscience which I am engaged in, because I do not pretend to be doing science. I am speculating in metaphysics and not at all pretending to be doing physics.Metaphysician Undercover

    You wrote:

    I've studied enough physics to know that a wave is an activity of a substance. That's simply what a wave is, and all waves are understood through modeling the movement of the particles within that substance.Metaphysician Undercover

    This is not a metaphysical statement. In this context it's a statement about optics, the physics of light, and it's wrong.

    This is the key point, the attempt to detect "relative motion" of matter through the ether. If it is the case that matter as well as the waves are both properties of the ether, then there would be no such relative motion, what we perceive as matter would just be a moving part of the ether. And, this is supported by quantum field theory. Particles of matter are understood as properties of the field, not distinct from (so as to move relative to) the field.Metaphysician Undercover

    Again - this statement is at odds with the fundamental basis of modern physics.
  • Bell's Theorem
    The idea he's presenting here is that of quantum field theory if I understand him correctly - he did bring that up before. Quantum field theory is, by my understanding, far from pseudo science, though the comparison between quantum field theory and the aether *might* be - it seems like at least a fair comparison to think of, but I don't know enough to say why it's not.flannel jesus

    This from Wikipedia:

    In theoretical physics, quantum field theory (QFT) is a theoretical framework that combines classical field theory, special relativity, and quantum mechanics. QFT is used in particle physics to construct physical models of subatomic particles and in condensed matter physics to construct models of quasiparticles.Wikipedia - Quantum Field Theory

    QFT has nothing to do with the propagation of light. Propagation of light does not involve movement of particles within a substance. Saying that it does is wrong. It's not only merely wrong, it's really most sincerely wrong. How wrong does something have to be before it becomes pseudoscience?
  • The von Neumann–Wigner interpretation and the Fine Tuning Problem
    I'm not sure I understand what you are implying. That an observation (or perturbation) precedes the so-called "collapse" is not in question. But "correlation does not prove causation". In my quoted definition above, "The observer effect is the fact that observing a situation or phenomenon necessarily changes it". The crux of the controversy seems to lie in the difference between "observation" and "perturbation".Gnomon

    I'll say it again one more time and leave it at that. No... I won't say it again, I'll just copy my previous comment here:

    The possible role of observation in "collapsing the wavefunction" or whatever is a completely different phenomenon than the observer effect.T Clark
  • The von Neumann–Wigner interpretation and the Fine Tuning Problem
    True. Although given the ways we've already found that life has adapted to take advantage of quantum effects, I figure it will probably come to play some sort of role. Obviously life uses quantum phenomena in that all chemistry is quantum phenomena, but it seems likely that adaptations for molecule level cellular machinery taking advantage of non-classical effects will be something we continue to find. After all, live evolved in our real world, not the abstraction we call the "classical scale world," and if optimal solutions involve quantum effects then life could easily have chanced upon them over 4 billion years.Count Timothy von Icarus

    Of course life has adapted to take advantage of quantum effects. Natural selection operates on organism's interactions with the world. The world at a basic level includes quantum effects. The classical world emerges from the quantum world. Again, that says nothing specific or direct about consciousness.

    You already have neat little experiments like this: https://www.sciencealert.com/study-suggests-spins-of-brain-water-could-mean-our-minds-use-quantum-computation

    https://iopscience.iop.org/article/10.1088/2399-6528/ac94be

    There has been a decent trickle of these, some related to how microtubules and tubulins re-emit trapped light, etc.
    Count Timothy von Icarus

    I have no doubt that much of how an organism operates uses quantum mechanical effects.

  • Bell's Theorem
    The Michelson–Morley experiment was an attempt to measure the relative motion of the Earth and the luminiferous aether, a supposed medium permeating space that was thought to be the carrier of light waves. The experiment was performed between April and July 1887 by American physicists Albert A. Michelson and Edward W. Morley...

    The experiment compared the speed of light in perpendicular directions in an attempt to detect the relative motion of matter through the luminiferous aether ("aether wind"). The result was negative, in that Michelson and Morley found no significant difference between the speed of light in the direction of movement through the presumed aether, and the speed at right angles. This result is generally considered to be the first strong evidence against some aether theories, as well as initiating a line of research that eventually led to special relativity, which rules out motion against an aether." 
    Wikipedia - The Michaelson-Morley Experiment
  • Bell's Theorem
    I've studied enough physics to know that a wave is an activity of a substance. That's simply what a wave is, and all waves are understood through modeling the movement of the particles within that substance. That's what a wave is, a specific type of activity of a substance which involves an interaction of its particles. Therefore a wave in empty space is simply impossible because there would be no particles there to make the wave. Yet we know from observation, rainbows, and other refractions, that light must consist of waves, therefore there must be a substance there which is waving.
    — Metaphysician Undercover

    Ok, suppose space is the "substance there which is waving". After all, the gravitational wave observations in recent years, (combined with electromagnetic observations of the source of detected gravitational wave observations) provide some pretty good evidence for space waving.
    wonderer1

    What M-M disproved is that the relationship between massive objects, bodies, and the ether, is not as was hypothesized. That does not prove that there is no substance which is waving, it just proves that the relationship between massive objects and the substance which is waving, is not as they thought it ought to have been.Metaphysician Undercover

    This is completely at odds with the fundamental basis of modern physics. There's no legitimate physicist in the world who believes it. Light propagates without a medium. If you post this on a physics forum, it will be removed immediately. It's pseudoscience.
