I realized why the idea of constellations has always swayed me. constellations are so very human.
our wonder of the stars is bone-sunk; we’ve been thinking and dreaming and watching and watching and watching since the beginning of time, and we looked for so long that we started making connections.
we played a celestial game of connect-the-dots; trying to find order in something so vast and trying to show that the stars are in everything and everything is in the stars.
we plucked pictures out of the infinite; there’s a dog, there’s a bear, there’s a lion, see? look, right there; the stars hold and mirror back everything.
but then it went a step further. instead of everyday things, we stopped picking out the cups and the bears, and instead we saw stories.
look, there’s Andromeda, chained to a rock and waiting to be devoured by Cetus. there’s Orion, and Hercules, and do you see Orpheus’ lyre? Zeus sent an eagle to retrieve it after Orpheus’ death and he placed it in the sky.
we did the most human thing imaginable: we wrote our stories into the stars. we filled the night sky; previously so vast, so unknowable; with our history. we forged connections to the stars and made it so our children will always know where they come from.

I had a professor in college who used to start solving every problem with the same dialogue.
Proff: What’s the first step to solving any problem? Class: Don’t panic. Proff: And why is that? Class: Because we know more than we think we do.
I think about that a lot tbh. It didn’t occur to me until much later that he meant for us to apply that dialogue outside of the classroom to any problem. Because we always know more than we think we do. We are all an amalgam of random information that ends up being relevant with surprising frequency.
The really funny part about the whole adults-playing-E-rated-games discourse is that it implies that adults should only and exclusively consume media that’s full of graphic violence and explicit sex, which raises some frankly fascinating questions about what these people think adulthood is.
In regards to the expensive nature of saffron…
‘stares into distance, takes a long drag off of what is, if you look closely, in fact a candy cigarette’
what if I told you…that saffron…is actually not that hard to grow at home for your own use.
Oh look a place you can buy the bulbs.
If you live in a climate colder than zone 6…as I do…plant them in containers and move the containers into a basement or garage during the winter.
They bloom in fall, and are quite lovely. And also you get saffron.
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).
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".
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.
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'.

the biggest lesson im learning is that nothing is as extreme or as permanent as our emotions convince us they are. nothing is certain and things are always fluctuating and there are always exceptions and there are always mistakes. there is always pain and there is always love. everything is a delicate touch away from changing

Okay I’m currently furious that migraines are often so blindly easy to treat and I had to find this out myself at the age of 26 when I’ve been to a neurologist since I was 11 lol so I’m about to teach you two neat and fast little tricks to deal with pain!
The first is the sternocleidomastoid muscle, or the SCM muscle.
This big red section is responsible for pain around the eye, cheekbone, and jaw, as well as some temple pain. Literally all you have to do is angle your head down a little, angle it away from the side that hurts, and then you can gently pinch and rub that muscle. I find it best to start at the bottom and travel upwards. The relief is so immediate! You can increase pressure as you feel comfortable doing so.
Here is a short and easy video showing this in action
The second is a fast and easy stretch that soothes your vagus nerve, which is the nerve responsible for calming you down. The vagus nerve, for those unfamiliar, is stimulated by deep breathing such as yawning, sighing, singing, or taking a deep breath to calm your anger in a tense situation.
You can stretch this out by sitting up as straight as possible (this does not have to be perfect to work) and interlacing your fingers. Put your hands on the back of your head with your thumbs going down the sides of your neck and, while keeping your face forward, look all the way to one side with just your eyes. Hold that until you feel the urge to breathe deeply or yawn, or until you can tell there’s a change. Then do the same thing on the other side. When you put your arms down, you should clearly be able to turn your head farther in both directions. If the first session doesn’t get rid of your migraine, rest and repeat as many times as necessary. I even get a little fancy with it and roll my eyes up and down along the outer edge sometimes to stretch as much as I can.
If you need a visual here’s a good video on it. I know some of the language they use seems questionable but this is real and simple science and should not be discarded because it’s been adopted by the trendy wellness crowd!
I seriously cannot believe I didn’t hear a word of this from any doctor in my life. Additionally, if you get frequent recurring migraines, you may want to see a dietician. Migraines can be caused by foods containing histamines, lectin, etc. and can also be caused by high blood pressure in specific situations such as exercise, stress, and even sex.
If any of this information helps you I’d love to hear it btw! It’s so so fast and easy to do. Good luck!
