  1. A quotation from Kurt Vonnegut

    The most important thing I learned on Tralfamadore was that when a person dies he only appears to die. He is still very much alive in the past, so it is very silly for people to cry at his funeral. All moments, past, present and future, always have existed, always will exist. The Tralfamadorians can look at all the different moments just that way we can look at a stretch of the Rocky Mountains, for instance. They can see how permanent all the moments are, and they can look at any moment that interests them. It is just an illusion we have here on Earth that one moment follows another one, like beads on a string, and that once a moment is gone it is gone forever.

    Kurt Vonnegut, Jr. (1922-2007) American novelist, journalist
    Slaughterhouse-Five, ch. 2 (1969)

  5. Follow up on Causality as an emergent phenomenon...

    (Ref. to: qoto.org/@Pat/1067226203347650)

    I found sources on the topic:

    Causality – Complexity – Consistency:
    Can Space-Time Be Based on Logic and Computation?
    arxiv.org/pdf/1602.06987.pdf

    Causal Emergence in Quantum Mechanics
    arxiv.org/pdf/1901.07471.pdf

    arxiv.org/pdf/1312.5916.pdf

    Causality theory for closed cone structures with applications
    arxiv.org/pdf/1709.06494.pdf

    Plus an older article, "CPT Violation Implies Violation of Lorentz Invariance" by O.W. Greenberg, which might be related to the topic.
    arxiv.org/abs/hep-ph/0201258

    I just found these yesterday on arXiv and really haven't vetted them much. There's more out there, mostly from the last decade or so. Not sure why I couldn't find this before -- I tried multiple times this year to find this stuff and now a week after I posted here I find a bunch of stuff. Go figure...

    Some of it is about non-locality and some also on temporal non-causality like disordered cause/effect. (Some authors use the term acausality instead of non-causality.)

    Also, there's a prof at U. Miss. (Luca Bombelli, www.phy.olemiss.edu/~luca/) with some nice reference lists:

    Causality in Quantum Field Theory
    phy.olemiss.edu/~luca/Topics/s

    Causality in Quantum Theory
    phy.olemiss.edu/~luca/Topics/s

    Causality
    phy.olemiss.edu/~luca/Topics/s

    Hope this useful.

  6. More detail on the non-causality poll...

    I'd expect adherents to quantum mechanics to choose "sometimes".

    Since QM appears to introduce uncertainty (probabilistic) in place of causality (deterministic) (i.e., it moves from certainty toward randomness), I don't see why a deeper dive couldn't move entirely to randomness (non-causality).

    Non-causality appears to be a generalization of nonlocality (or perhaps complimentary to it).

    Because of the results of the Bell test experiments, there appears to be renewed interest in explicit theories of nonlocality (e.g., extentions of de Broglie–Bohm theory) to make QM more palatable.

    I think the development of a construct for a non-causal extent with causality emergent at macroscopic levels (or emergent at the quantum/macro interface) could serve the same purpose, but I haven't been able to find anything on that.

    *** Does anybody know of anyone who is working on that? ***

    Here are some more hashtags to cast the net a bit wider. (feel free to comment even after the poll is complete):

  7. Where visual space emphasizes linearity, acoustic space emphasizes simultaneity—the possibility that many events can occur in the same holistic zone of space-time. Unlike visual space, where points either fuse or remain distinct, blocks of sound can overlap and interpenetrate without necessarily collapsing into a harmonic unity or consonance, thereby maintaining the paradox of "simultaneous difference".      - Roots and Wires - Freddy Mercury #quote #visuals #acoustics #spaces #simultaneity

  9. @science_quotes @jcastroarnaud
    I tried to make it general enough that anyone could respond, so no worries there.

    [Here's a post I just happened to see that talks about the importance of measuring principles, in the context of domestic abuse: c.im/@[email protected] ]

    The thing I could have emphasized more was the dual nature of the process. When we're stuck in one, the other will suffer.

    So 'letting go' cuts both ways. As you point out, often times our models run into problems, and we have to make changes. The disagreement between #experiment and #theory is a big red flag.

    The default seems to be to alter the theory in some way. This is not always bad, nor is it always right. The impetus for this is our confidence in the model, fueled by various factors. The farther back the model goes, the less likely people are to challenge it, or even go back to the start for a complete review.

    At the #fundamental layer of maths are simply the concept of numbers & quantity. If you're going to use them other than the way they come, the set is probably the next option.

    OTOH, not doing this is also creating #HiddenAssumptions that do pass along to the higher levels. The problem with problems is that we don't always know where they're coming from!

    The idea of 'continuous' reality, measured by a continuous number line populated by integers, and then modified by 'infinitely divisible units' between them in order to gain accuracy or change #scale, is the status quo that few ever bother to question.

    IMO, the time to do that re-examination is exactly in circumstances like you brought up. Looking only at GR, or only at QM, we might walk away with the impression of their correctness & #universality. But when they cannot be brought to terms with each other, then the next (or at least after a century of tinkering & failing) logical area to question is in the models & structures prior to them (rinse and repeat until resolved).

    Our notion of making single, #continuous measurements and being able to determine things like #simultaneity or mass-energy relations has failed in these areas.

    The similarity between the theory / #measurement relationship, and between practice / 'live' performance is what I was aiming to highlight.

    When not performing, all masters practice /revisit the basics on a regular basis. A good practice session 'lets go' of the conditions of a performance, and vice versa.

    3D chess is actually 4D chess (unless all of the moves in a game are made simultaniously).
