<BPlayer> Hi!
<Ellied> hi!
* UmbralRaptor stares at homework.
* UmbralRaptor probably needs those signs.
<Ellied> I just fixed the last one a little because the wording could be interpreted as "you're not unique at all and everyone thinks the same way" which is the opposite of what the third sign says and could be confusing.

<Ellied> UmbralRaptor: I'm imagining the package containing a vial and a micropipette. you extract however many µL you want and put it in your diluent of choice (or straight down your gullet)
<UmbralRaptor> Heh.
<Ellied> the vials themselves would probably indeed cost a lot less than packaged tablets with the same amount of active ingredient!
<Ellied> I guess pills are a lot like ICs, where the same chip costs much less in WLCSP than in DIP.

<FluffyFoxeh> nice door signs Ellied
<Ellied> thanks
<Ellied> people often say things like "I don't get what you're saying, but that's alright, I think it's just too complicated for me to understand" when I'm trying to answer questions about electronics, and that just kills me
<Ellied> like it's totally fine if you want me to stop trying to explain it but damn, give yourself some credit?
<soundnfury> Ellied: umm, there is such a thing as intrinsic intelligence. It's not totally determinative or anything — http://slatestarcodex.com/2017/09/27/against-individual-iq-worries/ — but it's there.
<whitequark> drink every time someone posts a slatestarcodex link
<Ellied> yknow, I thought about that, but I found that I don't really care. Every time I hear intelligence as a measurable one-dimensional quantity brought up, it's by someone who's about to say something shitty. If objective measurable intelligence does exist, it doesn't vary enough between the people who are going to read those signs to matter, at any rate.
<Ellied> I suppose it might just be a matter of varying definition. Maybe your brain is better than average at solving certain kinds of logic puzzles, but I have no reason to believe that's going to affect your ability to learn physics. It might mean you're better with certain types of math, but there's a lot more to physics than just pure math.
<Ellied> furthermore, I remain unconvinced that any kind of mental ability cannot be expanded through practice, or that anyone has some sort of predisposition - other than disinterest or lack of motivation - that makes them incapable of learning physics.
<Ellied> I guess it's easily possible that the line between interest and capability is blurrier than I'm giving it credit for, but I feel like I've never seen "I can't think in this way" so much as "I don't like thinking in this way" when it comes to people who don't succeed in STEM
<BPlayer> https://imgur.com/gallery/IBb776g I think this was a recurring xkcd theme, was it not?
<Ellied> there's also a huge self-fulfilling prophecy with that whenever someone gets the idea that they aren't smart enough to do physics, because it's really hard to believe in yourself when someone you look up to doesn't believe in you. The faculty in my department have been extremely supportive of me, particularly my research prof, and I credit that especially for my success learning electronics.
<Ellied> That's why I put that on a sign on my door, because *I'm* willing to believe in anyone who tells me they want to get good at anything at all.
<BPlayer> Ellied: I disagree. You either have that way of thinking (and like physics) so you do physics, or you don't.
<BPlayer> Perhaps it's a thing that gets learned in early childhood or something, but once you're adult, I've never heard of a person never being able to make sense of physics and later in life suddenly start understanding concepts significantly more than before
<BPlayer> In contrast, I often realize I just don't get things a non-scientifically "engaged" person does, and I think I am not the only one
<BPlayer> It is just a different "frame of mind". Maybe you can even train that, but I am certain that some think this way from childhood and some don't, and it's not easy to change it just like that
<Ellied> I couldn't make much sense of physics in high school. Now I'm about 80% of the way through a BS in it.
<BPlayer> Also notice a strong correlation between this "frame of mind" and professions and hobbies - people who do either maths or physics or programming are more likely to do either of the other two than the average person. As for the hobbies, I noticed a lot of chess players like maths and/or physics and/or programming
<BPlayer> Ellied: I am certain you at least had a solid foundation in logic thinking, then, and simply no interest for physics, perhaps
<Ellied> The first, perhaps (after all, my mother is a scientist as well) but I definitely had an interest in it then.
<Ellied> anyway, I changed the sign again; my main point is that there's no magic intrinsic number you have that says if it's possible for you to be good at physics or not, so I changed it to "your IQ doesn't matter."
<BPlayer> Maybe your teacher was bad at explaining... I don't know, really. But I am convinced that some people are more suited to do science (and less suited to do other things instead) and some are more suited to do other things, and less to do science
<Ellied> I also think I disagree with the common notion that you can only learn when you're young, so maybe that should be its own sign, or replace another
<BPlayer> As for "you only learn when you are young"... No, certainly not. But you have to agree, that's the time when you learn best ;-)
<Ellied> I agree that you can have a lot of skills in one field and hardly any in another, not disputing that at all. I do, however, think that what you're good at (and what you're not good at) is something you can change if you put in the time.
<BPlayer> Probably, yes. The human mind and body seems to have evolved very well to adapt to changes. But the question is how much time you have to put in to change that
<Ellied> It's the time when you learn best just because there's so much institution set up to teach you efficiently and effectively
<BPlayer> And I claim that some people, by predisposition, need to put in less time than others
<BPlayer> I am talking even younger. Less than 10 years, perhaps even less than 5. That's when you learn first breathing, then eating, then walking and talking... And all those complex things in the very first few years of your life
<Ellied> and I claim that, in the grand scheme of things, that ultimately matters very little. People tell me all the time that I'm really good at electronics, but I think I'm only good because I stay late at the lab every day and come in on the weekends to tinker with stuff, and not because I have any real predisposition for it. It took me a longass time to figure out how current and voltage actually
<Ellied> work and how to work with transistors.
<BPlayer> And then it just slows down, your body is never changing as fast as when you're very young, and with that it does not learn as fast
<BPlayer> I guess whether you believe in one "theory" or in the other is a matter of philosophy...
<Ellied> I spent a lot of time being wrong about all those things when I was little, so I came into university electronics with very little actual knowledge but a lot of passion for the subject, and I learned how to do those things the right way very fast because I was willing to put in the time.
<Ellied> I think it is a matter of philosophy, or at least as good as one, so my philosophy is that anyone can do this stuff if they really want to.
<BPlayer> I shall accept that :-)
<Ellied> and I, perhaps, do not concern myself with what actually causes people to want or not to want to do things; I'm sure that's very complicated as well.
<Ellied> I'm not here to convince people who hate electronics that they should study it, I just want to be here for the people who like electronics but think it's overwhelmingly complicated, which is most of my peers here.
<BPlayer> Anyway, I'll be back later. And no matter the philosophy, predisposition or lack thereof, I think most people are great and deserve to learn things if they want to. Having said that, thanks for teaching me that bit of electronics you taught me! :-)
