    Undergrad How many sorts of time are there in physics?

    It is just the arrow of time, never heard of thermodynamics time.

    Undergrad Help me understand indeterminism in standard quantum mechanics

    Just trying to contribute to the answer of PD here. In some interpretations, like Bohmian mechanics you get the same result every time because it is deterministic. It is deterministic without the need of parallel branches, but with the addition of hidden (nonlocal) variables.

    High School Interesting paper on QM in Scientific American

    When I first started in PhysicsForums I used to just post links of articles I found interesting. Every time I got various messages telling me "what is interesting??", "do you have a question about it?" and "are you just link dumping articles?". So please consider telling us something personal...

    Graduate Heisenberg's Re-interpretation of Bohr-Sommerfeld Quantization Condition in his 1925 'Umdeutung' paper (p12)

    Read on correspondence principle here: https://plato.stanford.edu/entries/bohr-correspondence/ As with all Bohr principles, the guy was so cumbersome about it that we do not really use any of his principles anymore only Bohr understood them.

    Graduate Understanding Barandes' microscopic theory of causality

    Do you have a reason to put an accent in Barandes -> Barandés? It is not the first time I seen it here.

    Graduate Understanding Barandes' microscopic theory of causality

    I mean something more human level. Imagine that one tries to reproduce an entanglement experiment à la Mermin, you drop some assumption and you get an interpretation. Bohmians remove the idea that particles cannot communicate, superdeterminists remove the idea that detectors are not conspiring...

    Graduate Understanding Barandes' microscopic theory of causality

    Can you provide a simple example of what would that look like?

    Graduate Understanding Barandes' microscopic theory of causality

    Sure but I am talking about the dynamics (the indivisible part).

    Graduate Understanding Barandes' microscopic theory of causality

    I can’t because I do not have any clear example of this kind of non-Markovian dynamics in other contexts.

    Graduate Understanding Barandes' microscopic theory of causality

    A mathematical correspondence is not an interpretation. Is a Wick rotation an interpretation? for me Barandes vision is missing a toy model preferably unrelated to quantum mechanics.

    Graduate Understanding Barandes' microscopic theory of causality

    This is the part were I remain skeptic, the dynamics remains nonlocal in the Bell sense but local in Barandes sense. We are repeating the same claims with different wording. Edit: I would be interesting to see which other interpretations are local in Barandes sense, probally every...

    Graduate Understanding Barandes' microscopic theory of causality

    As you say, he is saying that there is nothing "spooky" (I disagree). He is trying to focus the conversation on his redefinition of causality. My problem is that all that he has shown is already known. I don't get what is interesting of his causal locality. The real deal is Bell theorem, which...

    Graduate Understanding Barandes' microscopic theory of causality

    Again showing this is a play on words and definitions and not really explaining anything.
