  • Bernoulli’s explanation and Newton’s explanation are the same explanation made from different frames of reference. They’re equal, I don’t understand why people insist that one or the other is incomplete or that they somehow both have different contributions to an airplane’s flight. They’re the same. The airplane flies because the air pushes it up turning some of the energy from its substantial forward movement through said air into enough upward acceleration to counteract gravity. That happens both due to pressure differential AND the sum of the deflection of air in exactly the same measure, they are directly linked and have to be equal. Bernoulli’s explanation is one particularly nuanced and clever way of looking at and understanding the exact mechanics of how that happens and if you plug the resulting values into Newton’s math it matches perfectly. The zero “angle of attack” for a cambered airfoil shape is actually measured this way not by measuring the angles of the physical surfaces or anything like that. The Newtonian explanation is just another way of looking at it. Either way it requires intense computations to come to exact numbers, but the numbers are the same either way. The pressure differential of the air IS the mechanical force of the air, happening as an equal and opposite direction to the deflection of the volume of air the plane is flying through, either of which is what we call lift. They’re all the same thing, happening at the same time and yes you can look at them from different perspectives but that doesn’t mean one perspective is wrong and the other is right. They’re all accurately describing the same thing. It is useful to know both, but not necessary and it does not make either of them incorrect.

    This discussion always reminds me of the “airplane on a treadmill” argument where both sides read the premise differently and scream at each other that only their way of interpreting the question is right.




  • Clearly Russia has no idea how to censor different things in different ways to create a specific narrative for people to buy into. They’ve never done anything like that before, they aren’t masters of the craft of disinformation or anything.

    Totally unrelated joke, how do you know if a Russian is lying? You don’t, sometimes he could be telling the truth just to trick you.

    And I’ll throw in one of my favourite exchanges between two characters:

    “Of all the stories you told me, which ones were true and which ones weren’t?” “My dear Doctor, they’re all true.” “Even the lies?” “Especially the lies.”

    Trusting something coming out of Russia to be true is foolish, just as foolish is trusting it to be false. Nothing that say is reliable in the slightest or should be used to make any useful conclusion about the real world.


  • It is. The web was eventually corporatized and the corporations sucked all the air out of the room suffocating anything too small to compete. The fediverse is, if not taking it back, at least opening a space for those who don’t want to consume from a fully corporatized web. These include many of the people who used to make “websites” instead of “apps” or “platforms”. When people complain that it doesn’t have as much content as say, Reddit, I look at that as a benefit, it’s helping solve the (massive) discovery problem by self-curating thoughtful people who can curate content intelligently and provide real opinions and meaningful thoughts. The signal to noise ratio is much higher, and it’s refreshing.




  • Nuclear weapons in the current era of mutually assured destruction are strictly a deterrent, only useful in a hypothetical retaliatory strike but not as a realistic offensive weapon. The hypothetical situation where this would hypothetically be used would be after Seoul has fallen to the enemy and defeat is inevitable. By having such an ability, this makes it very unattractive for any enemy to try to conquer and fortify Seoul or put any existential pressure on South Korea by any means, since doing so enables the use of a retaliatory nuclear strike, since in such a hypothetical situation there is no chance of regaining Seoul left for South Korea to worry about. Therefore, as a consequence, Seoul is protected in a very material sense by a weapon that will never have to be used in any actual strike ever.

    They may only be a deterrent but they continue to be an extremely convincing and effective one.
