• The role of observers in MWI
    Using the expression, "observer effect" in QM conjures an image of the scientist staring at the particle, which is as bad as the "Earth in a basketball net" describing gravity's effect in cosmology. Even Einstein criticized the use of geometry to describe gravitational forces.

    To take a bit of the woo out of QM, instead one should speak of the "measurement effect", which alludes to the machinery doing that task, not the scientist, Gandolf.

    I am actually very unfamiliar with how they do such testsnoAxioms

    Thank you for a moment of honesty. These discussions are like the surface of a sphere, with the actual physics being the interior. It's always amazed me how physicists create the mechanisms to do these experiments. Isolating a single photon? Determining spin,etc.? You can get a PhD in experimental physics and many do - it's not all mathematically enhanced theory.

    distinguishing between linear interpretations . . .Andrew M

    The mathematics is linear - a specific kind of function or operation - and this gets confused with "linear interpretation", I think. And then there are "collapses" and so on. How is it possible to even discuss these things without a deep knowledge of the machinery of experiments? That's why its called the measurement problem, ascertaining a quality of an infinitesimal system without altering that quality or another quality. It's beyond me.

  • How Karate Should Be Taught
    what Im saying is bad is if you don't let a student test to meet the requirements because you want them to be patient by waiting longer.HardWorker

    Seeing karate as a martial skill only, I agree. Unfortunately, there's the baggage of the culture of the martial art to contend with.

    But it's hard to get people to see beyond the purely technical and not focus on going up number or letter or belt grades. I've seen this in a sport I was developing sixty years ago.

    That's true to some extent, but belts in karate, such as the black belt, is proof that you've met your sensei's standards.
    HardWorker

    I've never gone into martial arts. I was a rock climber for over fifty years, however, and there was no culture baggage there, purely skills and accomplishments. No rigid rules (well, the Olympics is another story), just get to it and climb. No belts, just designations like, being a "5.14 climber". Once you've done something that difficult you can wear the tag. Kind of like an invisible belt, I suppose.

    Say a comedian is lauded by the media, and your expectations are high, but you are disappointed in his performance. That's reality. Say a friend wants to dine at a new restaurant, but someone you know didn't like the food. Then you go there and are pleasantly surprised.

    It all has to do with expectations. Reality stays the same, but a heightened sense of reality occurs at times. No, there's nothing "more real".

    In social media, news, forums, and many other formats, things don't really work that way.

So, that's where it's a problemJudaka

    So, all you are interested in doing is assessing whether or not a commentator gives a "correct" analysis of why or how something happened in the public sphere? For example, all the different scenarios leading up to the January 6th incident. If there is no predictive value in this pursuit, why engage in it? Simply for the feeling of smugness it might provide? Or as an academic
    exercise?

    Apart from the fact that most mathematicians (including me) don't spend any time contemplating the possible Platonic nature of their subject, a more intriguing question is what makes a math subject or result "interesting"? Wikipedia lists around 25,000 math articles, so it's impossible for a single person to be more than superficially aware of more than a small percentage of these. What is it that drives these peculiar people to spend hour after hour pushing the boundaries of math further and further out? :chin:

  • How Karate Should Be Taught
    Patience is being taught as well as pure technical skills. Not unusual for an Oriental martial art.

    It sounds like you are young and eager to gain recognition among your peers. This is not unusual, either.

    What should one do - or perhaps not do? Is your sensei trying to teach you something about life?

    A good friend of mine designed the USMC martial arts program several years ago. Here is a requirement for advancement to 1st degree black belt:

    Training hours - 20 hours 45 minutes
    (1) Physical discipline – 12 hours 45 minutes.
    (2) Character/Mental discipline – 8 hours.

    Part of mental discipline is patience, and this is part of the warrior culture. You are not just learning how to trip up an opponent.

    But it's hard to get people to see beyond the purely technical and not focus on going up number or letter or belt grades. I've seen this in a sport I was developing sixty years ago.

  • The Bruces: Kit Fine
    The scenario involves a person in a universe that is perfectly symmetrically arranged around her center of vision.IEP

    One Bruce is a kind of mirror image of the other. Not a simple reflection.

    In FIne's example there are two descriptions yet it is unclear if there are one or two individuals.Banno

    I look at a graph on which are defined an x-axis and a y-axis. To the left of the y-axis is the line x=-1, to the right is the line x=1. There are two descriptions in this symmetric world, and two "individuals". But I see how one could say this is the same line in two places.

    Stretching the idea a bit, in math a homeomorphism means a continuous transformation of one object into another (doughnut to coffee cup, e.g.) preserving certain attributes. If one Bruce undergoes this process into the other, they are in a sense the same - homeomorphic. In this case they don't even have to resemble each other.

    I don't see any deep ideas here. It's simply another word game IMO.
  • Hindsight Analysis
    Academically, the study of economics is interesting to contemplate in this discussion. The dismal science is always looking backward, trying to determine patterns that predict certain outcomes. An example is something that is apparent now: the inverted yield curve. In the past this has been followed by a recession. Will that happen in the near future?

    When I write a computer program and it fails to deliver the result I want, I go back and analyze, step by step to find my mistake. So the outcome is a mistake, clearly, and I move backward in time to see what occurred.
  • Hindsight Analysis
    These so-called critical thinkers are at the mercy of what they're exposed to, they'll conclude in favour of whatever was the most recent outcome, based on whatever material comes their way.

    Although there are personality conflicts in math, this type of argumentation is minimized by a resort to the basic logic underlying mathematics. Exceptions occur in Foundations, where things are less stable and entrenched.

  • Analytic philosophy needs affirmative action?
    But I also think the very act of proposing a new game is a 'move' that should be part of an ongoing debate, and that there is space for this kind of thing. It's just not what everyone is interested in engaging in, and so you may get a few disgruntled coughs and eye-rolls in the seminar room where the old game is being played. What really needs working out is what 'the terms of debate' and 'game' amount to.Welkin Rogue

    I read what you write from the POV of a retired mathematician, and find similarities. A PhD thesis may occasionally break into entirely new ground, but most often they extend or generalize an existing subject. Afterwards, these ideas might lead to new territory - that happened for me. It's interesting to hear of "philosophies" of other academic subjects.

    How many different subjects constitute philosophy in academia these days? In math Wikipedia has over 25,000 topics. It's a bewildering world in which to function. I forget more each day even though I stay minimally active.

  • Emergence
    A change in one IS immediately experienced by the entangled object,universeness

    A change? No, a measurement of one is somehow connected to a measurement of the other. At different frames of reference one or the other can seem to be "first". "Collapse of the wave function" seems to run strongly here, but I still suspect it has more to do with solutions of differential equations "existing" simultaneously: superposition. For example, a particle is at z=1+2i, but the equation describing its position has solutions z=1+2i and z=1-2i. Which holds? Make the measurement and find out. Collapse the damn thing.

    I'm naive about this subject, I admit. It just feels better to circumvent the woo when possible. :cool:
