  • 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.





  • I mean… just about everything that’s old-world, north of Africa, west of the Urals, and north/west of Istanbul is considered Europe.

    The extent of Europe is very broad, with even Iceland being considered a part of it; and it isn’t bound politically. For example, Denmark is considered to be in Europe but Greenland (a territory of Denmark) isn’t, but then again, the Faroe Islands (another territory of Denmark) is.

    You might be thinking more along the lines of the EU (European Union) which is the third iteration of the dominant political/economic entity in much of Europe, born in 1993 when it legally became a person. Where the EU actually reaches across the entire globe due to overseas regions, collectives, and municipalities.
