A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    • 3.1) NEW RULE as of 5 Nov 2024, trying it out
    • 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    • 3.3) Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

It's crazy that a 60 ton metal airplane can just fly (lemmy.world)

I flew for the first time on a plane last week and I've seen planes take off at the airport. It looks crazy. But being on one is totally different like holy shit. The thing just FLIES. It just.... Soars... Through the sky! Like whoa man. Wtf... It's crazy. With how much these things weigh, it's insane to me the thing can just go up and bam, there we are, we're flying now. Like wow... Dude crazy.

I'm partial to the Newtonian explanation myself, I was explaining my interest the first time I saw an illustration of the Bernoulli principle.

in fact, I just wrote about The Newtonian explanation a few minutes ago:

"the Newtonian makes more practical end complete sense to me sense to me as an explanation for a lift.

maybe the confusion comes from calling the motion of pushing air down "lift"

push-off.

hm. what the heck is an appropriate antonym for lift...

spring-hold.

oh, buoyancy?

maybe we should switch our talk from lift to buoyancy.

rather than generating lift, velocity through the air generates aerodynamic buoyancy due to the increase in downward pressure, or rather the compressed air beneath the airfoil."

Sorry, as an engineer, this whole "shape of a birds wing makes air move faster over it" pisses me off to no end.

Airfoils are shaped the way they are for drag purposes, not whatever crazy things they say, we could make them like massive triangles and they would still work.

sure, i get it.

he did come up with that half explanation 250 what years ago, so I'll give him a pass.

kind of a bummer that a half explanation is his most famous 'discovery" even though he did so much

No, yeah, Bernoulli was a genius who did a lot otherwise, he should be remembered for all his other scientific contributions..

But you fuck one goat...
