Welcome to the discussion of US Politics!

Rules:

  1. Post only links to articles, Title must fairly describe link contents. If your title differs from the site’s, it should only be to add context or be more descriptive. Do not post entire articles in the body or in the comments.

Links must be to the original source, not an aggregator like Google Amp, MSN, or Yahoo.

Example:

  1. Articles must be relevant to politics. Links must be to quality and original content. Articles should be worth reading. Clickbait, stub articles, and rehosted or stolen content are not allowed. Check your source for Reliability and Bias here.
  2. Be civil, No violations of TOS. It’s OK to say the subject of an article is behaving like a (pejorative, pejorative). It’s NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
  3. No memes, trolling, or low-effort comments. Reposts, misinformation, off-topic, trolling, or offensive. Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
  4. Vote based on comment quality, not agreement. This community aims to foster discussion; please reward people for putting effort into articulating their viewpoint, even if you disagree with it.
  5. No hate speech, slurs, celebrating death, advocating violence, or abusive language. This will result in a ban. Usernames containing racist, or inappropriate slurs will be banned without warning

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

That's all the rules!

There was a British comedian I remember from a while back.... Matt something... that talked about meeting a Texan couple on a plane once and the wife expressed her amazement at the marvel of flight, which is fair because flight is pretty amazing. But instead of just being amazed, she then said something like, "we'll never know how it all works". Like a collective we, like everyone. Like she thinks that aerospace engineers are just guessing, trying out throwing shapes into the sky until something doesn't drop to the ground. "Nope. Sphere didnt do it. Probably shouldn't have filled that one with people, either. Let's try the cube next!"

Some people are so stupid they don't realize that they are stupid and that plenty of people, MOST people, in fact, are smarter than them and understand a lot of stuff they don't. Like it's not even Dunning-Kreuger because they dont know the first thing about the subject at all, and they will even admit that often times. Just unadulterated hubris to assume their ignorance is universal.

Everything is simple if you don't know anything about it.

Isn't there some question about the specifics of the mechanism of lift itself? Not like "this shouldn't be possible!" but more "it's easier to explain than it is to understand"

[–] kryptonianCodeMonkey@lemmy.world 35 points 1 week ago (1 children)

No, the science and engineering is well understood and can be calculated entirely in models that use this knowledge to precisely predict thinks like lift and drag. There is no guess work or mystery about it.

However the common "facts" that we are often taught as explanation to children and the layperson for lift are wrong and/or incomplete. The Equal Transit Theory, i.e. the idea that when a wing splits the air, the air above and below must meet at the same time on the back of the wing causing the air on top to have to move faster due to the greater distance to travel, is just not true.

However that lower pressure above the wing that doesnt actually result from the Equal Transit Theory, that part is true. It is caused by the deflection of air on the underside of the wing causing the higher pressure underneath and lower pressure over the top. Lower pressure over the wing does in fact cause a component of lift due to Bernoulli's Principle. But it is also not the entirety of the source of lift. Other components include the Coanda Effect from the curvature of the wing redirecting air downward, as well as the just simple propulsion caused by the propeller(s)or jet(s) and downward deflection of air hitting the underside of the wing, which is basic Newtonian motion (3rd law).

Huh, okay. I don't really keep up with all of the little fandoms, so thanks for that!

Like she thinks that aerospace engineers are just guessing, trying out throwing shapes into the sky until something doesn’t drop to the ground.

Having worked in my checkered past in aerospace for a decade or so, there's a very small grain of truth in that. While there is a lot of enginneering that goes back to first principles (physics and math), there are also what are euphemistically called "empirically determined constants." That's because, even when the equations are known, they can sometimes be a pig to actually compute ("ill-conditioned"), requiring absurd amounts of computer power.

So if I were on the plane next to that couple, I'd have said "Yep, we're flyin' on a wing and a prayer and there's a non-zero chance we could auger into the ground at any time. But don't fret, it doesn't happen all that often."

The God Emperor of man wills it, that's how flight works
