@ivalbor @Geezer185 @mathelirium Nothing was overlooked, never said a board makes a very good wing (it doesn't). ;-) That was just to illustrate the basic principle.

@MariusReinecker @Geezer185 @mathelirium Мариус, вы правы. Плоское крыло действительно работает. Но Вы упускаете параметр стабильности процесса. Плоское крыло стабильно, как шарик на вершине пирамиды по отношению к шарику у её перевернутого основания. Надеюсь, понятно объяснил.

It is often said that the lift on a wing is generated because the flow moving over the top surface has a longer distance to travel and therefore needs to go faster. This common explanation is actually wrong.
English
@tripvvire @mathelirium Yes, basically Newton's 3rd law. There's a little more to why this applies here, but it does.
English
@almosnow @mathelirium The reason why this works like that is a little less obvious, the long and short of it is, because real air is viscous. If it weren't, at all, this wouldn't ... "fly". ;-)
English
@MariusReinecker @mathelirium This. This is so obvious it hurts, yet some "scientists" miss it.
English
@Rolando_tillit @mathelirium Correct, but that being the case doesn't make the Newtonian explanation wrong. The vorticity field is the cause for the deflection. But that's probably not what this is about, seems to be more about how you feel.
English
@MariusReinecker @mathelirium Wrong, it's the vorticity that generates lift. The vorticity creates the down/up/sidewash that redirects the airflow.
English
@Geezer185 @mathelirium It's quite interesting, actually. Bulge of the wing is called camber, the straight distance from leading to trailing edge cord. Any wing, ever, is a compromise between drag and lift, at a given speed the plaine is supposed to operate the most. And altitude (density, friction).
English
@MariusReinecker @mathelirium Thanks. Yes, makes sense. I was not disputing flat wing would not work - I was thinking of a simple paper plane.
English
@Geezer185 @mathelirium I does. Nevertheless, a flat wing still works. Aircraft build for speed have barely curved profiles. Reduces drag, too. Strongly bulging profiles you'll find f.i. on gliders (short profile, long wing), or any plane optimized for slow speeds.
English
@MariusReinecker @mathelirium Having top surface curved more than underside adds to lift?

@Jesii_ca_M Of course. Those women are the victims and had no choice in the matter, getting forcefully exploited by men. They are completely free of any responsibility, whatsoever.

@LisaBritton I intensely dislike tattoos, particularly on women. I can appreciate the art, if well executed with an overall aesthetic concept I can appreciate. But especially on an attractive woman, it's like gang graffiti on a Greek temple, making them look like a public toiletstall wall.
English
Women are now more tattooed than men. Thoughts?
Alex@notcomplex_
Tattoos have become far more popular over time, especially among women, who are now more tattooed than men.

@MarkN1038 @dom_lucre I do know who he is, though. It's the Archangel Gabriel!

@dom_lucre I googled her and now know less about her than I did before, which was nothing.

🔥🚨JUST IN: Hollywood actress Laura Benanti was in complete disbelief as not nobody recognized her on a plane.
Benanti: “Not a single one of them recognized me and I could not tolerate that obviously.”

@40kARTdotcom Defo need A gender, otherwise you suck.

@kmcnam1 ... the robots probably are the one exception I usually don't argue with. They're mostly pretty polite and helpful, actually. Some too much so, the weasly slimy sycophants can be pretty draining. Not Grok tho. It can occasionally really walk the line to brutal.

@venturetwins That is VERY context-dependent. That the LLM can actually look at pictures and help you craft descriptions is fantastic. For me, half the time, LLMGrok's edited prompts ..suck. But it's a great learning tool for how Imagine imagines, and why the prompt sucked, so you get better.
English
The new Grok Imagine model is particularly good when you use the LLM to help write or refine prompts ✨
I often start with something simple, take the output to Chat, and ask for help iterating on an edit or enhancement.
You end up with something much more detailed!

Grok can help you come up with great prompts for images and videos

@elonmusk ... also, you should rename it to "Imengine". Like, Imagination Engine, contracted. Way more cringe, maximum uniqueness and recognizability.

@kmcnam1 All those inkjets also check their ink level and refuse to print when they're still, like, a quarter full, because "else we can't guarantee print quality"🙄 and you have to buy new cartridges when the old ones still had like 100 prints in them. 😠

@elonmusk Were you aware of the parenting trick to check on your kids, telling them to immediately send them a selfie in some random pose you told them?
Yeah. You just murdered that in its sleep.
Grok is awesome, I work with it all the time, but ... y'know.
