  • I definitely relate. I also kind of have this obsession with using only open source software which also tends to hinder my creativity because some of the open source alternatives to things have steep learning curves.

    Anyway, I think this is one of the things that makes me great at math but terrible at learning math. If something is complicated, I have to chew it down to the bone and then rebuild back to the original complicated thing.

    As such, I’m really good at doing all sorts of math and even have some of my own weird identities/constants memorized, but it takes me a lot of time and effort to learn new math from a textbook instead of (re)inventing it myself.




  • It’s clearly just saying that the surfaces on which the ends of the cylinder lie are metric spaces with distances defined using Chebyshev or Taxicab metrics based on pentagonal tilings of the parabolic plane so the ratio of a circle’s circumference to diameter is 5.

    Since it’s a cylinder we assume the vertical dimension is Euclidean and voila the math checks out geometrically.



  • I have had the same thought before. Unfortunately conservation of energy is not enough to ensure entropy is monotonically increasing.

    Say you created a tiny universe with the same average entropy of our universe and then you connected it to the edge of our universe. Energy is not conserved because you just added some, but entropy is because you didn’t create an entropy potential.

    Say you had a warmer object and a colder object and you took all the heat energy from the cold object and added it to the warm object. The energy of your system was conserved, but its entropy decreased, violating the second law.

    You can use violations of the second law to violate the other laws because entropy naturally wants to increase due to probability (which cannot be violated without destroying math and logic etc.).

    In the scenario above, if you put some fluid between the two objects you could harness convection via a turbine to harvest energy. Even though your action of moving energy around didn’t create or destroy energy, it created a sort of entropic potential energy. Kind of like how teleporting an object to a higher elevation doesn’t really increase any energy in the universe since all mass and kinetic energy were conserved, but you’ve now increased the potential energy of the object which would become kinetic energy as the object falls back down. You could then harvest infinite energy if you repeated the cycle.

    In order for one to move energy around via magic without violating entropy, one has to increase the entropy of the universe by at least the same amount it would take to move that energy without magic.

    The solution I thought of was just that magic accelerates the expansion of the universe. Technically this still allows for some “impossible” stuff locally, like a perpetual motion machine or free energy generator that will eventually die but on the timescale of human lives seem infinite.

    Magic would get weaker with use over time as the universe nears it’s equilibrium temperature, and you would be shortening the lifespan of the universe every time magic is used. But even if you used it excessively, you probably wouldn’t be shortening the lifespan of the universe by very much unless you were using magic to like move black holes around or rearrange galactic clusters.


  • That still is a violation of entropy because you’ve increased the “order” of energy in the universe as a whole, which is not possible.

    If you can violate entropy, one can create a more than perfect Carnot Engine (or in general just a heat engine with efficiency greater than 1) which would allow you to generate an infinite amount of energy in the form of mechanical motion.

    Unless in creating/gaining “mana” one is accelerating the entropic decay of the universe as a whole equal to or greater than the amount of entropy reversed locally (eg spells must produce heat and be inefficient at converting mana energy into work), magic would violate thermodynamics and allow for infinite energy creation.


  • Fuck the square cube law. If there is any magic that can freeze things / make things cold, the second law of thermodynamics is void, and by extension the other two are as well.

    Perpetual motion machines? Hell yeah. Infinite energy? Hell yeah. Being able to create negative energy by decreasing entropy thus being able to create antigravity and simulate negative mass? Hell yeah

    Yeah so all of these apply. It’d make more sense to do this daily. That way some of them might not be there lol

    Edit: except sticky notes. I take my notes on hundreds of different notebooks and note taking apps then forget where they wrote everything, like a sophisticated person lol



  • Well the svg file itself wouldn’t be, but whatever tries to render the image might think the file is infinite since it’d loop around forever. Come to think of it, I’d imaging there are probably safeguards in place to prevent svg files like this hypothetical one from being opened because they’d run as an infinite loop


  • Wait, is it possible to create a real infinite droste effect with vector graphics since they aren’t limited by resolution?

    As long as you can do recursion in the xml it should be possible to make an svg that’s “infinitely” recursive yes?

    (I have no experience on this topic)


  • I have literally started to add every thought in my head into obsidian and already it feels like someone could probably recreate my mind from it lol

    The best ADHD feature is the ability to link notes, even ones that done exist. So if you have a really specific idea about some topic you can just write it down, link it to the topic, and then get back to whatever task you were doing when the thought arose. Then when you have time you can find the idea again as long as you remember the topic or topics you linked it too



  • I recently had to install windows for a research project and the fact the “latest version” i downloaded moments before needed to update while installing and then again needed to update twice after it was installed pissed me off way more than it should.

    Also gotta love that my laptop can go 5+hrs on a charge with arch and xfce but lasts less than 2hrs on windows.


  • Start talking about something and get so lost on tangents trying to explain all the precursory information they need to understand that original thing I haven’t explained yet that I’m now debating something entirely unrelated and have forgotten the original point I’m trying to make.

    Bonus points if I end up losing my train of thought during one of the tangents and now don’t even know what I said two seconds ago and have still forgotten the original point I was trying to make.

    Also not being able to do simple things I plan/need to do, like laundry or writing an email, but then spend 4hrs straight building something incredibly complex from scratch just to test a random theory I had that has no other usefulness.

    Yes, remember it is totally immoral to pirate things from corporations who actively make everything worse for everyone.

    Here’s a guide to what sites you should avoid so you don’t accidentally get movies, shows, books, music, etc. without paying FMHY.net
