  • 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.




  • So the bar for you is generally knowing a non-zero amount of things about mental disorders but for others in this thread it’s having to know the person from the article?

    Setting yourself up for an easy win by default there, smart. What’s not smart is apparently assuming you’re the only one in this thread that is even faintly familiar with mental disorders and therefore others must bow to your subjective opinion.

    You don’t have to know any particular person to know that having a mental disorder doesn’t magically un-asshole them or shield them from all criticism; origin from disorder is an explanation, not an excuse. I know I’d never expect, or frankly want, anyone to suffer my presence if one of my many oddities caused them some kind of significant distress.
