    imagining fields (not forces,

    Yeah that thing. Except that they were dubbed “magnetic lines of force”. Also, I remember it being separately explained that even though they were called that, they didn’t represent the direction of force (of course not, or you’d not need the right-hand-rule and left-hand-rule).

    Looking at the iron shavings though, it seemed more like low potential energy regions/ stable regions.

    Also it give a feeling of being analogous to fringe patterns.


  • For anyone whose magnet related memories are not filled with various line illustrations of the forces, that’s probably it.

    And even though my head is full of those illustrations, I don’t seem to understand how the iron fillings and ferrofluids make the shapes they do instead of just sticking to the magnet. And I am too lazy to do the maths to make myself understand.


  • Not really.

    They are just getting rid of any and every liberty that any reasonable society would provide.

    Not the rights though. We never had such rights. We just didn’t realise those were needed to be written down because others didn’t violate those expectations.


    Even in an anarchy, without any written rights, we would have those liberties, given a reasonable society. Just not here.












  • Well, that’s how it tends to be in most places.
    You don’t get caught for downloading; you get caught for uploading.

    Using a similar logic to distribution via DVDs. Only the seller gets into trouble. The buyer does not.


    Another point, opening a web page means downloading it, so if someone wanted to frame someone for downloading something, it would be very easy to make such a trap. This, accompanied with CSAM and network monitoring could be used to easily get any person using the internet, in jail, just for opening the wrong link. So, the laws require much more information regarding intent and such.






  • This is a nice example that also makes me think more questions.

    • Will the hole punching be forward or backward?
    • Assuming infinite deceleration, for an observer on the other end of the barn, will the barn be punched through, before or after the pole-pusher has stopped?
    • For the pole-pusher, will the barn be punched through, before or after it has stopped?

    Gets more interesting

    The only time any information can be encoded onto entangled particles is when they’re created.

    If that were the case, then we aren’t really doing FTL communication, unless we manage to entangle them at a distance. No?

    OIC, it’s still useful if we want to make a secret key and send it somewhere. Then both sides can take a reading sometime in the future and they can then use whatever cluster of entangled particles they saw, as the symmetric key.
