Okay I’m Currently Furious That Migraines Are Often So Blindly Easy To Treat And I Had To Find This

i don't think you are wrong that diagnosing ppl with anxiety and adhd and depression is lucrative, but that analysis is difficult for me to swallow wholeheartedly, as someone who has chronic depression that makes it hard for me to function at the level im expected to. it's still a disability

it is totally a disability but the ways that  “the level you are expected to function” at in society purposefully leaves your emotional needs unfulfilled I think is the main reason depression is so widespread. like the circumstances of capitalism in tandem with a biological predisposition will take you tf out but a lot of people don’t have predispositions to these conditions and still develop them and framing their fear, sadness and distraction as individual illnesses to be combatted through spending money is valuable to several industries. like its a disorder if it “impedes your daily function” but everyone’s daily function is shaped by the cruel pointlessness in the first place. they should be seen as logical reactive states that reflect societal failure. It’s just weird to me to see a diagnosis of depression, anxiety or adhd rn still being framed first and foremost as an individual chemical deficiency when sadness/anxiety/lack of focus or motivation are completely natural responses to what we’re all going through. it would be weird for the majority of people to respond to this situation with immediate hope or drive. just because something’s wrong with you doesn’t mean something’s wrong with you 

Quantum Mechanics Itself as Emergent 'Phenomenon'?

Recently, we've been talking about emergence - more explicitly about emergent phenomena in many body systems. But what if the concept of emergence would not only apply 'within' quantum mechanics but also 'outside' the theory? What if quantum mechanics itself is an emergent theory from a classical-type underlying 'reality'? This is exactly the approach of an interpretation of quantum mechanics, called emergent quantum mechanics (EmQM).

Where is EmQM located in the 'zoo' of interpretations?

The 'zoo' of interpretations and alternative theories of quantum mechanics can be classified by their answers to the violation of Bell's inequalities. Bell's Theorem is a theory-independent result and therefore must hold for any possible approach which reproduces the results of standard quantum mechanics. Roughly speaking, the theorem's consequences are that one either has to give up the traditional understanding of realism, or the idea of locality. E.g. Rovelli's approach and QBism belong to the camp which gives up traditional realism and adheres to locality, whereas Bohmian Mechanics sticks to realism and therefore embraces nonlocality. In general, hidden variable theories belong to this 'realist' camp.

EmQM suspects a locally deterministic theory from which standard quantum mechanics emerges. Walleczek and Groessing (p. 2, [1]) suppose that instead of "absolute quantum randomness" there might be "quantum interconnectedness" - indicating the presence of some kind of nonlocality, e.g. nonlocal causality. Hence, this approach seems to belong to the above called 'realist' camp, in which a traditional understanding of realism is embraced and the price to pay is nonlocality, more neatly called "quantum interconnectedness".

Why EmQM?

Walleczek and Groessing [1] argue that a metaphysical fundament is needed in order to unify general relativity and quantum mechanics. Since general relativity is strictly deterministic and standard quantum mechanics inherently indeterministic, the metaphysical fundament of each theory starkly opposes each other such that the lack of unification seems inevitable. However, setting a microscopically causal fundament for both branches of physics, as well as the focus onto emergent phenomena, might yield a solution. For instance, the theory of quantum gravity already relies on the idea of emergent spacetime - together with EmQM it may be possible to lay a metaphysical framework of 'all physics'. Nevertheless it might be questionable, in my view, how this is supposed to work with an approach as EmQM in which nonlocality is a cornerstone, i.e. possibly causing trouble with causality as we know it from relativity.

EmQM and Bohmian Mechanics

Since EmQm and Bohmian Mechanics (BM) belong to the same, 'realist' camp, both seem to be related. Both claim to describe the underlying 'reality' beneath standard quantum mechanics. Both approaches share the belief that standard textbook quantum mechanics does not have descriptive character regarding the nature of reality, even though the theory is empirically successful. Then, standard quantum mechanics is regarded as an 'effective' theory.

However, two approaches can be well compared by regarding how they attempt to reproduce standard quantum mechanics. One main aspect in this respect is the appearance of randomness. Both approaches claim to be fundamentally deterministic and therefore have to explain why we experience the randomness of standard quantum mechanics in our laboratories. Bohmians do this by introducing so called "absolute uncertainty" [3], which is a consequence of the quantum equilibrium hypothesis. Effectively, this means that a universe in which Bohmian Mechanics governs the dynamics, it is impossible to gain knowledge about the configuration of a system beyond the probability distribution determined by the wave function ρ=|ψ|^2. Hence, the complete configuration of point particles, their positions and velocities do exist, but there is no experimental access to it. This limited knowledge is supposed to be the source of randomness and uncertainty that we encounter in standard quantum mechanics:

"This absolute uncertainty is in precise agreement with Heisenberg's uncertainty principle. But while Heisenberg used uncertainty to argue for the meaninglessness of particle trajectories, we find that, with Bohmian mechanics, absolute uncertainty arises as a necessity, emerging as a remarkably clean and simple consequence of the existence of trajectories." (p.864 [3])

Instead of making use of a (more or less ad-hoc) hypothesis, the appearance of randomness in EmQM seems a bit more natural: Only because the underlying dynamics is supposed to be deterministic, this does not imply pre-determination. This is something one can already observe in purely classical systems: The more complex a system is, the more uncertain is the outcome (often referred as "deterministic chaos"). A minor change in the boundary conditions can cause a huge change in the result. Thus, the central point is emergence:

"Critical in this context is that emergent phenomena are subject to unpredictability as a consequence of the intrinsically self-referential nature of the governing dynamics [...]." (p.5 [1])

In comparison, BM formulates its theory in a rather rigid manner. It formulates postulates from which the theory can be deduced. The issue with this is that these postulates have kind of an ad-hoc character. In my view, EmQM circumvents these problems by being less strict/definite. This approach does not seem to have a fixed formalism yet (at least I haven't found analyses on the same level of rigor as there are for BM), while the research seems to be more focused on exploring how emergence can enter the picture - as e.g. 't Hooft does in [2], where he describes explicit examples of possibly emergent symmetries. (Disclaimer: maybe my impression is incorrect, since I have only superficial knowledge about EmQM.)

Regardless of this point, both approaches seem to be interconnected in the end. Walleczek and Groessing (p.2 [1]) claim that a future EmQM would include BM. Hence, in my view, it might be possible that EmQM might support BM in the sense that it lifts the necessity of possibly ad-hoc appearing postulates as formulated in BM. Thus, any theory of quantum mechanics (orthodox or unorthodox) might not only yield emergent phenomena within the theory but quantum mechanics might unravel itsel as an emergent 'phenomenon'.

What do the Gods care. They breathe aether not air. They drink ambrosia not water. Their blood is ichor and immortal whilst ours is rusting, slow rotting iron. But here’s what they do not want you to know. Without our prayers and tributes, their mighty Olympus turns into just another ruin. Their aether grows polluted with unrest and darkness. Their ambrosia bitters and their immortality begins to feel like a burden. Ask a God to name his weaknesses. If he is honest, he will tell you they wear mortal skin and go by names like yours.

Yeah I love manipulating my friends for my own gain, the gain is called "hanging out", obtained via such cruel tactics as "showing interest in stuff they like" and "being generally complimentary and charming"

dude seeing these Mega high quality images of the surface of mars that we now have has me fucked up. Like. Mars is a place. mars is a real actual place where one could hypothetically stand. It is a physical place in the universe. ITS JUST OUT THERE LOOKING LIKE UH IDK A REGULAR OLD DESERT WITH LOTS OF ROCKS BUT ITS A WHOLE OTHER PLANET? 

it strikes me as somewhat uncomfortable that so many people focus on asian stories only after the events of the past couple of days. people dm me for the first time in months and asian creators get spotlighted (which is lovely), and yet it feels so performative. why? because so many of these ppl dming me and whatnot have never been interested in interacting diverse content or speaking out about the stories of poc—it’s like they’re doing this to solely gain brownie points. in a few months’ time, they won’t be doing all this anymore. they’ll go back to their silence, to not caring about asian creators. that’s what makes it performative. the stories of asian people shouldn’t be heard and spread only when they’ve been murdered and/or when their pain finally makes it onto news headlines.

Give me body horror in magic.

Give me pyromancy that burns the skin off your hand until your bones are showing. Give me arcane that cooks you inside-out from manaburn. Give me cryomancy that cracks your skin and chips it away. Give me necromancy that causes your teeth to turn necrotic and your eyes to glass over white.

I don’t want cute magic. I want magic to be a raw and dangerous force. I want those who harness it to feel the full effects of what a great and terrible thing it is. I want mages who wear the effects of their magic on their skin and in their bones.

That’s the good stuff.
