    I don’t understand the meme. The figure is from a paper about false positive readings in MRIs, using a dead salmon supposedly thinking, and the meme is suggesting… the fish was alive?

    Not much context + vague point = poor excuse for a meme.

    Add the context that this is a dead salmon, then claim that salmon are immortal of something, idk.
















  • Voyager is never coming down. Even if we wanted to bring it back, we couldn’t in this century, maybe ever.

    Eventually it’s slagged remains will find a black hole to rest in, which is a different down at best, but even the black holes will evaporate, assuming the universe lasts that long. This fate is so far beyond the concept of down that there must be nuance in the claim, especially when talking about astrophysics.

    Every interplanetary craft defies the phrase, and even orbit demands a deeper understanding. “What goes up must come down” sounds good and covers everyday life, but just like Newtonian physics it breaks down at large scales.

    Something axiomatically correct would always be true (for the axioms we have taken). Perhaps you could take “On Earth” as an axiom here, but that’s a very restrictive axiom that you need to specify. Thus a more nuanced take: “What goes up must come down, unless it leaves the atmosphere.”

    Not that I’m using axioms very rigorously. They’re usually used for math things. My informal usage was to evoke the sense of absolute truth. Of a statement so obvious that it doesn’t need proof. I find Tyson speaks in terms of “this is” rather than “this suggests” or “we have evidence for”. He speaks like an omniscient narrator speaking a story rather than a communicator of science.

    Also, ‘Falsity’ is a word, and I think you’re actually using it correctly; it’s the opposite of ‘Veracity’ and also a noun for a lie or untruth. “The falsity of the statement” seems right, but it’s also old and very underused. I think a better word would be ‘Falseness’, but ‘Falsity’ in neat!


  • When I say axiomatically correct, I mean something self-evident or aligned with fundamental principles. An example of something that’s axiomatically correct would be: “Gravity makes things fall down” or “Lines that aren’t parallel will eventually cross”.

    Something that sounds axiomatically correct, but isn’t, would be “What goes up must come down”. It sounds true, and was practically true for thousands of years, but every spacecraft relies on it being false, that things can stay up forever.

    I don’t have an example from NGT off the top of my head, but this sentiment is why I’m not a fan of his, despite being very into space and astrophysics.


  • I haven’t seen season 1 or 2 or unseasoned yet, but 5 is much better than 4. I hope this trend of just adding more to what alteady exists continues, like another dreadnought, another machine event, more secondaries, more cave layout variations, all good.

    As for the actual season content, the Drillivator is a very nice point defense variant in that it’s also moving and has cover. Salvage’s Uplink/Fuel Cells has always felt snowbally, in that it gets way harder if dwarves go down, and there usually isn’t much cover (skill issue, I know). Escort has the drilling sections, which encourage dwarves splitting up and can really frontload difficulty when drilling into a cave (korlok + spitballer + leach = FUn!). Sabotage has the hacking parts, where Hack-C finds the least convenient location to drop, and usually gets suprise glyphids up his ass. The Drillivator actually feels a lot like meteor cracking, but in a much smaller area and without crackers landing on cliffs. Altogether I quite like it, and I need to learn how to leverage the hand drills during the scanning section.

    The Core Stone is quite interesting. Crawlers are a nightmare to deal with, especially right at the beginning, but I think there’s a big wave right at the start, so focusing on the crawlers rather than the Core might be the way to go. The rift spawing looks incredible, and the Core rebuilding it’s Stone reminds me of the Ommoran Hearstone in the best way, with all the floating shards. I was worried about the crawlers being too hyper realistic body horror when I saw the concept art, but they fit in really well!

    All in all, I’m having lots of fun, and it looks like the dwarvelopers are too. It makes me very curious about Rogue Core!
