  • What happens if our mathematical system is proven to be inconsistent?

    Jump

  • Realistically, that doesn't happen. At least not if we consider mathematics to be the useful kind of mathematics. The stuff that helps you do statistics/finances/engineering. Because that type of mathematics is based on reality and for the mathematics to be inconsistent would mean that reality is inconsistent, and then we have much much bigger problems.

    As for the higher abstract maths (which is closer to philosophy anyways) yeah such things have happened many times and led to revolutionary insights each time. An example is when we started basing everything on set theory (which in medieval times did not really exist). But that's a philosophical question, not one that concerns daily life.

  • I would even go as far as to say that models are neither right nor wrong, they just are what they are. Like a flower is not right or wrong for blooming a certain way, it just does what it does and does not care about your right and wrong. This is simply because there is no morality outside of human society and therefore no way to establish right or wrong.

    In fact, it is us who are right or wrong when we are using a model. We can use it in meaningful ways or nonsensical ways, it's our choice. That's why it's us who are right or wrong.

  • Eh, i've struggled with this for years but eventually found my peace.

    You see, there's two types of electric current: Electrons moving through a wire, and protons moving through water (the second one is also called a pH gradient, it happens e.g. in cell membranes of chloroplasts, fascinating stuff, check it out).

    Basically plants do photosynthesis, which is extremely similar to what solar panels do. They generate an electric current, and in that current, positive charges move, so the "direction of current flow" is the correct one.

    I have come to accept that the current inside living beings is more important than the current in all the machinery, because without life there would be no machinery, so life deserves to get the "correct" current.

  • to be honest, it might have a significant impact. the US tech today serves a global market, but if that market gets reduced to just the US, that is probably a significant cut.

  • Yes i am sure. If the pressure is equal on all sides (i.e. inside and out), you don't need a skeleton. Consider how a thin foil of plastics (or a jellyfish) in deep sea does not get ripped apart.

  • I think the reason why water bugs taste way better is because they have less exoskeleton. Which they don't need because they don't need to carry their own weight, since the water carries most of it.

  • Very interesting!

    I agree with your point that a user account without a canonical URL to send messages to could not have an inbox, and therefore never get DMs or notifications if somebody commented on their post.

    I had not thought of that before but it seems obvious to me in retrospect. Obviously, to receive messages, you need some kind of machine-address, where these messages will be sent to. And that's what this is for:

    They expect it to point to a valid JSON-LD document describing the actor which they can request.

    Because it describes the inbox address.

    Your data hoster is the instance you have your account on, not the one the community is on. Your instance just shares the posts you make on it with the community, but all it receives is a copy. The canonical version is on your instance, discuss.tchncs.de.

    That's truly fascinating knowledge, thank you. It makes sense because in the ActivityPub protocol, each user has an outbox, and published posts go there. So of course, other communities simply reference that instead of actually holding the post.

    This means, then, that communities aren't actually so much lists of posts, but lists of references to posts, i.e. when i post to /c/a@lemmy.world, that community simply gets notified about the canonical link to my post, which actually resides in my outbox on this server. Thanks for making me think about all of this!

  • This also applies to renewable energy btw. Some people seem to think we can't start with the energy transition before we've figured it all out, including storage for the winter and at night.

    Let's just build solar panels and wind mills and see how far we can go with that :D much more productive that way.
