    If you assume that a “bullet” is a unit of momentum (the mass and velocity of a bullet) and “square child” is actually just referring to the mass of a child who happens to be square shaped and not the mass of a child squared, then “bullets per square child” is describing valid units for a velocity

    The state (as defined by Engles, Marx, Lenin, etc.) is the problem. Like this is exactly what it does by definition.

    If the government forms an alliance with the market it becomes a slave to the market.

    There are more homes than homeless, more food than starving kids. Life saving medicines can be extremely cheap to produce but are sold for fortunes. Everywhere you look, the bourgeoisie are literally holding people’s lives for ransom… and the government does nothing.

    In fact the government does less than nothing. It is the government that facilitates the hoarding of these resources. It is the government that enforces patent laws that allow life saving medicines to be kept from those in need. It is the government that enables and legalizes this racketeering by the rich.

    When you live in a society where politicians talk equally (or more) about how they’ll help the market as they talk about how they’ll help their citizens—which is what their job is supposed to be—are you really surprised?

    Are you really surprised that a government which chooses to let its people go unhoused just to keep the real estate market up is a government in which wealth holds the power? Are you surprised that a government that shuts down worker strikes and forces compromise on the side of the exploited rather than solely on the side of exploitative corporations is a government that can be manipulated by the owner of multiple massive companies?

    There is nothing surprising here. The system is working exactly as it is intended to. The problem is not a few members of the bourgeoisie colluding to manipulate the state because that’s how the state always works. The problem is the state.

    If you would like to learn more about “the state” I suggest you read State and Revolution. That’s what made me switch from “oh we just need to tax the rich” to “the rich should not exist.” It also is just kind of impressive how Lenin describes many things that are very relevant today despite the fact he wrote this short book over a century ago.



  • Not to be that guy, but science is basically anything that gets studied/tested/researched. If you have the ability to cast spells and someone notices similarities and tries to categorize spells, that’s science. Studying how spells are made would be science. Studying the limitation of spells would be science. Testing news spells would be science. Etc.

    So the big question is really how well understood is the science of magic in your world?

    Does anyone actually know how it works or is it more like quantum mechanics with lots of theories but each still has limitations?

    If magic is widespread and the beings using it are curious, chances are they’ve experimented with it and possibly taken notes about their experiments.

    If magic offers great advantages then knowledge of it might be closely guarded by practitioners and not easily learned.

    If magic can only be practiced by a certain species/family/etc. then general knowledge of how magic works could be much less accessible to the general population making it much more mysterious.

    If not, then it’s likely there are schools that teach it to those who can use it and even those who can’t use it would likely still be taught about it. I mean, if you’re an engineer and you want to shape titanium and some spell can do that more easily than a mill or lathe, you’re going to want to know.

    If you can heal with magic, non magic doctors would still want to be in the know about what can or can’t be cured with either medicine or magic.

    If you mean science as in advanced physics or having digital devices, things will get more complicated if you want to make a logically consistent world. Like very complicated to the point it might take the joy out of world building. For example…

    If there’s a spell that creates light/heat, where does the energy come from? You either violate thermodynamics or that energy comes from somewhere. OR the energy disappears after a while which might be a cool thing to think about.

    If there’s a spell that freezes things, it violates the laws of thermodynamics in a big way unless more heat (entropy) is generated somewhere else. If this generation somewhere else is somewhere really far away, you can create an infinite power source pretty easily.

    Arguably teleportation may or may not violate relativity which, fun fact, might be the reason gold is gold colored and not silver colored so if you break relativity you might break some weird shit from the color of chemicals to the laws that hold your proteins together.

    If magic has any visual effects, like an aura, it means magic interacts with the electromagnetic fields in a way that generates or manipulates photons. This could fuck up lots of digital stuff but also might be dangerous because color corresponds to frequency. If you can change the frequency could certain spells emit gamma radiation? Do invisible spells produce infrared or UV? If some spells interact with photons but some don’t then why?

    Furthermore, air is a substance. If you cast a spell that explodes objects how does the spell know when it hits the object and not an air molecule? If the spell isn’t instant why does it have a specific speed? If it’s effected by matter then would casting a spell under water go slower? Does water explode if you cast an explosion while in it or does the spell hit the nearest solid before causing an effect?

    If magic doesn’t interact with matter between the caster and the object, what medium transfers the information? What particles carry the magic force(s)? If magic particles don’t interact with physical matter how does a being made of that matter cast a spell? How does the being specify a target?

    If spells have incantations, what makes those work? Can any sound create magic? Could a parrot accidentally cast a spell? If it’s in a specific language, why? What beings created that language? If magic just randomly happens to be a set of sounds that humans can make that seems rather coincidental yes?

    If only certain creatures/races/families can use magic, why? How does the genetics of a being effect if it can or can’t interact with a fundamental field of this universe (magic)?

    If it is genetic or physical in any way, with enough scientific study it should be possible to replicate it or remove it.

    If it is metaphysical like it comes from the ‘soul’ then religion and science will overlap. Furthermore beings would likely use this to be prejudiced against any living thing that can’t do magic.

    If all living things can do magic what about viruses? What about single celled bacteria? What specifically defines “living” in the context of magic and by what mechanism do those criteria enable the use of magic?

    Anyway, the point is that if you try to get to technical and logical, it’s going to become a pain. The best bet, in my opinion, is to try avoiding the abundance of magic. If magic existed in our universe it would already have multiple scientific disciplines devoted to it. You’d be able to major in magic but more importantly, most of the general population would know fundamental things about magic and its limitations which means you’d likely need to explain your magic system more.

    If you don’t want to get technical it might be best to not let your characters get technical. Keeping the knowledge of magic secretive/mysterious would help with this.

    Or you can get completely lost in the world building and start writing out how many different magical fields there’d need to be and how they interact with elementary particles and how the thermodynamics of spells is rectified by events in those fields giving the illusion that thermodynamics was violated while still preserving the typical physics required for chemistry to remain unchanged and then think to yourself wait, wasn’t I going to write a story? Why am I researching theoretical math?

    See I agree with your last statement. I mean “any” is a stretch but yeah there probably are other systems involving distance based forces that we could draw similarities to chemistry from.

    I guess the issue here is that my argument is there are similarities and your argument is that one shouldn’t point out similarities unless there are enough of them…?

    Your first paragraph implies you thought I meant just setting these systems statically next to each other would create a stable orbit. You’re right, that would be wrong. But I don’t think I ever mentioned stationary combination. Furthermore, while regular chemistry could work like that, in the real world every atom is moving. The bonds form when atoms get close enough. This is why temperature increases chemical reactions. More motion means more “collisions” that aren’t really collisions but you get the picture.

    Objects in space are also constantly in motion. If you want to bring two stellar systems together, you need to give them velocities relative to each other. Or as you put it, momentum. This could be enough to ensure a stable system but it requires that the velocities at least a roughly specific which is what I meant when I said system chemistry would be highly directional in my original comment.

    As for magnets. You could say both atoms and magnetic systems run on similar forces. You could make the argument that they, like atoms, have components which are constantly in motion and that if perturbed enough one could overcome those forces and break the system into its individual components.

    However the behavior of the system as a whole is not similar to atoms because it cannot form any bonds of any kind with other similar systems.

    If you were able to find magnetic monopoles which may or may not exist, you could probably build a system that is much more atom like than a gravitational system. But with magnets that have dipoles, even a ferromagnetic material would be drawn to one pole or the other. I suppose you could get up to two ferromagnetic bodies to orbit a rotating bar magnet if the velocities and distances were right, but you wouldn’t be able to combine them because moving any magnet closer would disrupt the conditions needed for stability.

    Magnets are much more sensitive than gravitational systems because the objects have to be large relative to the system and close together whereas gravitational systems can be ginormous like Alpha Centauri.

    Anyway it’s fun to think about what exactly I would count as chemical like properties.

    I’d say they are mostly just the following:

    1. A unit system is made of different components that are held together by some distance based force in a specific state of equilibrium; the unit has a space near the center containing the majority of the mass, and the unit can on some scale be treated as a particle.
    2. Both components and units are separated by a functionally empty medium
    3. Units can lose/gain/steal components from other units
    4. A unit’s components and their amount/locations/motion change the way it interacts with other units
    5. Some components can combine into a single component, split into multiple functioning components, or decay
    6. Units can decay spontaneously or as a result of physical interaction
    7. The removal or addition of a component to a unit can cause the unit to become unstable but does not always do so
    8. Units interact with other units via a distance based force and can form stable multi unit equilibrium states, combine into a single unit, or destabilize entirely.
    9. The specific equilibrium state (shape/configuration)of a multi unit system affects how it will interact with other units or multi unit systems.
    10. Units can be removed from multi unit systems by other multi unit systems or external units with or without destabilizing the rest of the system from which it is removed.
    11. Units and systems with similar enough configurations will react in similar ways

    I think that covers it. So if you can find a system that fits those then I’d say there are similarities between them and atoms/chemistry. I will honestly be pretty excited if you do because it will be interesting.

    Gravitational capture occurs when one object enters a stable orbit around another (typically referring to natural orbits rather than orbit insertion of a spacecraft with an orbital maneuvers).

    So saying it “is not possible” is verifiably wrong. The perceived rarity of gravitational capture is most likely just due to how empty space is, not the unlikelihood of stability.

    On that note, I think you might want to do some math yourself. You seem to be laboring under the impression that there are limited or maybe only a single exact state of stability for systems like this. “You have to perfectly set the velocities and magnetic moments” I’m not sure about magnets but I am sure about gravitation, and you don’t need to be very precise at all.

    If you know how to code I’d suggest you try simulating two bodies with random masses traveling at random velocities. You’ll see that many times they do swing apart and a few times they will directly collide but there is a wide range of stable orbits. Sure, if you wanted to get perfectly circular orbits, you’d need to be more precise, but circular orbits are not necessary at all. Most orbits are at least a little eccentric, and eccentric orbits are still stable orbits. Importantly, they can be created without precision.

    Next, while binary systems are assumed to form during star formation as you assert, the quote I listed from Wikipedia says it is possible for binary systems to form via gravitational capture.

    Anyway, since that wasn’t enough evidence for you I decided to find an example of a combination system. Fortunately I didn’t have to look very far.

    Alpha Centauri (our nearest stellar neighbor and triple star system) is a specific example of stable combination. Rigil and Toliman are main sequence stars that likely formed the way you listed since they are very close together and roughly the same size with slightly more massive than the other.

    However, Proxima Centauri is a red dwarf that orbits the two circumbinarily. It is .2 light years from the other two which means it is roughly 5% of the distance to us from the barycenter of Toliman and Rigil.

    However, despite the distance, it is “gravitationally bound” to them and its orbit has a 30deg inclination relative to them. This out of plane motion, the large distance, and the eccentricity of its orbit, imply that Proxima Centauri did not form from in the ways you listed. It may have formed in the same nebula as the other two, but it also very possibly could have travelled before getting gravitationally captured. In either case, it was gravitationally captured by some means and has formed a stable system despite having an out of plane velocity.

    Proxima Centauri even has circumstellar planets, and its small mass and large distance from the binary pair mean it very easily could be stolen from the system if another main sequence star passed closely by. So it’s a great example of this “bonding” I’ve described.

    Now magnets. Your magnet analogy is not similar to these scenarios because electromagnetism is highly directional. I don’t think you’d be able to combine systems of spinning magnets in any stable configuration other than a straight (spinning) line of them. However—as shown by the Alpha Centauri system—it is very possible to form stable multistellar systems from the combination of two stable systems.

    Lastly you are correct that there are many many differences between atoms and gravitational systems. I mean shit, we don’t even know how atoms really work. String theory and particle physics don’t play nice and there are many more theories for unifying relativity and quantum physics that would impact what the “true” internal structure of an atom is like.

    However, as mentioned in my last comment, that is not the point! My point was simply that there are some similarities and that you could do certain things with them that would have chemistry analogues. Does that make sense? I’m not saying “these are the same” I’m saying “it might be possible to use these in some similar ways to atoms.” And I’ve now found proof it is possible because of this debate, but the point of my original comment was curiosity/discovery not debate.

    Firstly, you are wrong. Binary star systems are a good example this. Secondly, thank you for helping me find more similarities between atoms and stellar systems and learn new words.

    From the Wikipedia page for Binary Star System:

    it is not impossible that some binaries might be created through gravitational capture between two single stars

    Again is it unlikely? Hell yeah but I covered that point previously and the important part is that it is still possible.

    Next, I need to thank you because you helped me find out that your “nuclear type reactions” happen and are similar to nuclear combination of atoms.

    The orbits of planets in a binary system can be circumbinary which would be the “nuclear type” as you called it where the stars (or most massive body in the system) begin orbiting each other and planets orbit around both as though they were a single massive object.

    However, they can also be circumstellar (as I described previously) meaning the two stars orbit each other but the planets orbit only one star each. This would be much more analogous to an ionic bond (though again without polarity) where two atoms are attracted to one another but do not share electrons.

    Furthermore, it seems there is even more similarity as the circumbinary systems are more unlikely to break apart but the circumstellar type require stars to be far enough away would make them more easily dislodged. This seems similar to nuclear decomposition being much harder to pull off than chemical decomposition.

    But wait, there’s more.

    Some binary stars orbit each other so closely that they share the same atmosphere, giving the system a peanut shape. While most such contact binary systems are stable, some do become unstable and either eject one partner or eventually merge.

    Even if the stars get close enough to touch, they can still be differentiated and are “stable” This seems much more like a nucleus since the “particles” are packed tightly together and the whole “becoming unstable means I eject a particle” kind of screams radioactive decay.

    Anyway, there are “periodic solutions” (stable configurations that follow a cycle) to the three body problem and there are likely some for n-bodies. So contrary to your assertion, it is possible to make a stable system with multiple massive bodies that do not combine “nuclear type”.

    As you can see from the images on the Wikipedia page, these systems have unique shapes which is what I was referring to as the analog of proteins having specific shapes.

    Lastly, the first line of my original comment was that yes, these solar sustems are reminiscent of a wrong model of the atom. I’m well aware of the structure of electron orbitals and Schrödinger’s equations for electron position etc.

    My point was not to say that stellar systems are structured just like atoms or behave exactly like them either. My point wasn’t even that there are more similarities that differences. It was simply that there are similarities between the two and that you could build some analogous structures/chemistry with gravitational systems.

    Oh yeah eventually they will. But eventually protons will decay. Could you do something with these bonded “atoms” before they collapse? Probably not as much as you can before an atom decays but yeah you’ve definitely got at least a few million years for most systems right?

    While others have correctly pointed out that the model of atom which is reminiscent of a solar system is not accurate. I would like to point out that systems of massive bodies in space could possibly be used in some ways similar to atoms.

    The closer you get the stronger the pull is, but if you’re going fast enough, you can find stable configurations. This means it is possible (though incredibly unlikely) that if two solar systems interacted the right way, you could get a stable combined system. Two systems could orbit each other with or without sharing planets which is reminiscent of certain kinds of atomic bonds. You can even have system interactions where one system steals a planetary body from another. Sure there’s no ionic bonding because gravity isn’t polar but it’s still possible to create “bonds” of some kind.

    Also, the specific configuration, total mass, and number of massive bodies in each system would affect how it interacts with any other system, kind of like chemical properties of elements.

    If you throw a massive enough thing fast enough you can rip a solar system apart kind of like how throwing a neutron or nucleus fast enough at an atom can break it apart.

    Complex gravitational systems can have specific and often complex physical structures/shape too, which could be argued as similar to the way proteins have complex and specific shapes. These shapes would change the way the systems interact with other systems because gravity and distance are related. Again creating these stable configurations would be unlikely but still not impossible.

    Hell, there are even weirder similarities too. Stars and black holes “decay” and the collision of planets can yield different numbers of “particles” which interact in new ways because their mass is different.

    Sure, gravitational systems are not nearly as stable as atoms, they probably couldn’t be ordered into a table like elements, and do not operate on exactly similar forces like atoms. System-chemistry would also be very directional which would be tedious, but I think it’s cool that it could be possible to do similar things with gravitational systems as you can with atoms, even if they don’t have similar structure or internal properties.

    I grew up in a rural Utah town. Here are things I attempted to correct my teachers on while in elementary school with the result of them telling me if I continued to disagree with them I’d be sent to the principals office:

    • Evolution does in fact exist and “monkeys aren’t turning into humans today” because that’s not how evolution works.
    • There are different methods for multiplying numbers (lattice)
    • The amount of protons in an atom is equal to the number of electrons not neutrons. Yes for lighter elements they can be the same but isotopes are a thing (yes this actually happened and the next day we watched a bill nye that said exactly what I was saying. Of course bringing up the fact I was right and she was wrong was not a wise course of action.)
    • If the earth was a few feet closer to the sun we would not die. The earth actually is closer and further throughout the year on the scale of a few million miles. (Asserting that this was also not proof of god’s existence was similarly not a wise thing for elementary me to do)
    • “Foot zoning” has been debunked and you should tell people to see a real doctor when they feel sick
    • Those white homeopathic medicine pills don’t do anything
    • If we know how disease spreads and it’s due to human action/choices then it’s not gods punishment because he couldn’t control the spread unless he controls those people.

    I’m sure there were more seeing as I frequently had to “pull a card” in nearly every class and most times had no idea why what I said was wrong. There were definitely some on global warming but I don’t remember the specifics.

    Anyway, it is almost certain that I would argue some things that were wrong, after all, I was like < 12yo and surrounded by people who would constantly tell me the encyclopedias I read were wrong (I didn’t like chapter books and encyclopedias had pictures) but even then, there still definitely were things I was and still am right about.

    And it probably would have been better for my mental health growing up if I hadn’t thought “wow if all these adults believe this thing then it must be true and I must just be an idiot” No past me, you were right, they were wrong. Essential oils are bullshit and definitely don’t cure cancer, animals do feel pain and deserve to be treated with respect, and yes the cult you were raised in makes no sense whatsoever. Basically the entirety of your hometown, and most of your family members are just delusional. You’re not wrong and they don’t just not believe you because you’re a kid, they just don’t believe in evidence, and there’s no evidence one can use to convince people who don’t believe in evidence.

    Edit: to clarify, this was a legitimate public elementary school not some weird religious institution. Its just the typical education found in small Mormon towns in Utah.

    Well actually it’s the other way around. The reason imaginary numbers were invented was to solve a problem we’d been crying over for centuries.

    Then, as in most cases, solving one problem opens the door to millions of other problems like why in the fuck does the universe use these imaginary numbers we made up to solve cube roots?

    Why is i a core part of the unit circle with like ei*pi ? “Oh that’s because i is just perpendicular to the real number line” ?! Say that sentence again, how the fuck did we go from throwing sharp sticks to utterly deranged sentences like that? More importantly why do utterly deranged sentences like that accurately describe our universe and what is the next ludicrous math concept we’re going to discover is integral to the function of the universe?


  • “The Yellow Wallpaper”

    Tap for spoiler

    It’s written as journal entries by a woman who may or may not have been insane before she got locked in an asylum or possibly just a room in her house by her husband. There’s a woman in the wallpaper who creepily crawls along the wall but actually it’s her shadow because she’s the creepy woman crawling around the room and rubbing up against the wall. Of course you don’t really know this until she starts really sounding crazy and starts ripping up the wallpaper trying to free the woman in the walls. In the end her husband returns home and either he faints or she fucking murders him with the blade she uses to sharpen her pencil. The book ends with her thinking she’s been freed, not by escaping through the now unlocked door but by entering the yellow wallpaper. There’s also a creepy film adaptation we watched that was… unsettling.

    It was quite scarring for most of the kids in my 7th grade class.

    Also I’ve only just now realized that wallpaper back then could have contained arsenic so going insane from being in contact with it constantly enough to stain your skin is a very real possibility.
