    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.


  • I think modern science has disregarded the scientific method as not required anymore to make claims about what we “know”.

    Yeah, that’s one of the pretty big problems I see happening in the current scenario.
    People becoming way more hand-wavy about having been proven wrong, which sometimes seems (we can’t know whether it actually is) outright disingenuous.

    The religion related scenario I painted was probably possible due to how long it lasted. Maybe we will have to wait for this one to last long enough to know whether what it yields is as undesirable or more.
    For now, at least I don’t see it going in the same direction as the religion power, simply because it’s not the science people that are holding power, but other politics oriented ones. So if it were to go in an undesirable direction in the far future, it would have to be in some other direction.


  • then aren’t you admitting that so far you haven’t known the answer?

    That’s the point of science. Humility and requestioning yourself everytime someone gives new input, instead of sticking to some old text that some human wrote and multiple other humans over a long period of time, translated; all using lossy translation techniques.

    This mentality is similar to what you will see from many people in places of power (no matter how small), trying to evade criticism using the same social power that they need to be responsible about. Just that in case of religion, one has found a scapegoat, so unassailable that it can be reused indefinitely.

    You can see, which approach is more desirable by simply considering the following facet of the result that we have when we have a science majority vs a religion majority…

    • In times when religious organisations were in power, those who criticised them were killed and their works destroyed to as much of an extent as possible
    • In times when scientific thought was prevalent (scientific organisations don’t get social power owing to their lack of charisma, which stems from the very basic attribute of the modern philosophy of science - that one can be wrong) the religious organisations criticising science are not destroyed until almost extinction, but are allowed to question all results and have the opportunity to aggregate their views.
      • You will always see some kind of religion vs another
      • You might see “science-ism” vs some other religion
      • You will see political orgs (which represent one of the peaks of social power in the current age) vs some politico-religional orgs trying to destroy and silence the other
      • You will not see science trying to silence a religion
      • You will see businessmen trying to use scientific results as a stepladder to social power. You will also see them fail in the long term, simply due to the nature of science.








  • Yeah, one big problem of man I found was the severe lack of explanation of what the command is mainly intended to do. It’s as if the user is expected to run the man after knowing what purpose a specific program exists for, which, I guess is what it is intended for. I tend to rely on the package manager’s information and other similar sources for that information and man mainly for determining the exact usage.

    I don’t at all expect man to be useful for someone who can just follow written instructions.
    The reason being than man is just supposed to tell the user, what typy stuff needs to be done for specific functionality. And most programs tend to be doing some small thingy and not fulfilling the user’s whole requirement in one go.
    Meaning, to be happy with just man, one needs to be able to create a solution for themselves by properly fitting little parts and that is already more than half way to being able to do programming.

    Your man -a intro example and what followed, made me more confused than before of what you were trying to say, so I am just trying to go with the feel of it for now.

    Maybe knowing that you can use / and then whatever string of text to find something in the man page (because it uses less to paginate the output) would be useful for some of what you said. So you can do /-a and press Enter to start searching for “-a”. And the reason for it being so far is because it is in the “OPTIONS” section.

    I now feel like someone who reads a lot of legal documents would be fine with man pages. Was this format made by someone in that field?


  • Other than stuff like ffmpeg - which has so many features that a man page just can’t cut it; and sed - which doesn’t have a simple hyperlink saying “you go here to learn sed regexp”, most man pages do what I need them to do.

    You just need to learn the basics of how the man page is organised and what the brackets in the SYNOPSIS section mean and that makes using them much easier.

    We also have man man for that purpose.
