  • To be pedantic: It’s not necessarily an equal amount of mass, it just has to accelerate (this includes deceleration which is acceleration opposing a component of a vector of travel) any amount of mass along and opposite to the vector of the plane’s acceleration due to gravity so long as the amount of mass (and the averaged amount of that mass’ acceleration in the aforementioned direction i.e. force) is in ratio with the planes mass and it’s acceleration due to gravity.

    There’s a lot of other pedantic caveats but they’d make this comment far too long. The main thing I want to convey is that mass doesn’t necessarily matter but rather force (m*v) and also that the “suction” and thereby acceleration that a plane’s airfoil experiences is also it causing an acceleration on the air around it by decelerating it along the path that it wants to flow. It all depends on frame of reference.

    I suck at explaining things, this video might do a better job at getting the idea across.

    Male is literally the same kind of word just for the opposite sex/gender; the term specifically points out the ability to produce sperm (in many dimorphic species) for the purposes of reproducing with the opposite sex. It’s literally just saying “your distinguishing characteristic is your ability to inseminate another of your species” and is just as dehumanizing.

    The reason you would use it in that context is because it’s “[gender specific noun] of all ages.” Where if you were to say “boys of all ages” or “men of all ages” it would imply either all ages under 18 or all ages at or over 18.

    This is the same context in which you would use female as a noun, as girl/woman implies a restricted age range, just as boy/man, when you specifically don’t want one.



  • I’m a young queer man(-ish) and after voting for Kamala have never felt more at fault for literally every problem the US has than whenever I open Lemmy. The blue party that I’ve been registered to and campaigned for since day one seems exceedingly good at making sure I know that, despite everything, somehow I’m the problem.

    Like fuck, I finally get why people suddenly get the urge to be ‘the fucking problem’ after being told they are the problem for so long.
