You do need fancy swash plates that'll stand up to the stress. So if your helicopter's not powerful to do aeros, there's no need to build them so they can, right? So now they have good engines, rotor heads are built to take the stress and do the combined blade control that you need to perform stuff like rolls and loops and so on and to make it even easier, there's flight computers controlling all the moving parts these days.
their wings generated lift from the vortexes
Like Concorde landing. It doesn't have flaps, but the vortexes generated on the leading edge of the wing at high angles of attack make the wing appear bigger (longer camber) to the rest of the air flowing over it and so it can generate more slow speed lift. Downside is it creates drag and so it needed lots of thrust to land.
Has anyone mentioned the effect that gravity has on time?? If not why not??
I guess that's maybe because its not self evident. And as far as I'm concerned its beyond magic.
As you were.
photography related. Mrs McMad has recently got into cyanotype. Interesting and just about explainable, but she has just had a play with wet cyanotype. Watching the image change over a few hours is total magic.
If only uploading photos was easy. Here is an insta link for anyone interested

So not only do people in the C-suite on the top floor get paid more, they also work shorter hours. Double bastards!
can bumble bees loop the loop?
can bumble bees loop the loop?
The amount of bumble bees I find lying on their back and needing help to flip over would suggest not, but they do try.
But they could if they had titanium rotor heads.

That’s what happens when bumblebees do a victory roll having managed a loop, they’re so exhausted they can’t land properly.
It's lack of sunshine. Bumblebees are fueled by pollen, nectar, and sunshine.

Despite knowing exactly how they work, how can a metal needle in a plastic groove sound that good?
Dark arts.

NASAs recent strategies for doing stuff in space.
"So when we get to Mars we're going to use our pixie duat to let us hover while the lander is lowered on a thread of unicorn hair, then once it's down a baby lander will unfurl it's own wings and go off to explore"
Or
"we'll fly a long way from earth, then say the magic word and a tiny box will grow and grow until it's a massive solar panel, then we'll squish our eyes around until we can somehow see clearly and then we'll look at tiny bits of space send back some amazing photos"

Old lighthouses used to float the entire lighting apparatus on a bath of mercury so that it could be spun round smoothly
There is still one in existence, the only hand wound, kerosene powered lighthouse in the world, Elbow Reef light station in the Abacos.
Wind turbines, they turn so slowly but that tip can be travelling at 300mph.
Atoms visualised in diagrams are not to scale, not even close, they are drawn like that for ease of explanation, in reality it would look more like the solar system, with vast expances of space between the nucleus and electrons, etc. They are mostly empty space.
That desk or armrest you are leaning on is not as solid as you might imagine!

Flying birds. No way that’s possible, especially the little fat ****ers.
The fact that atoms are full of nothing. Great expenses of empty space but literally empty in this case.
Spoked bike wheels. They’re in tension for gods sake. Even understanding the physics of it I’m still convinced it just actually be witchcraft.

Is that some sort of weird abbreviation for Timmy Mallett? Cos if so, I don't think he's either 'science' or 'magic'. He probably belongs in the Disproportionate Annoyance thread, in truth.
I recently read that water isn’t actually wet. It has the ability to make other things wet but isn’t wet itself. Blew my mind and if true is clearly the work of a magician hellbent on breaking my tiny, fragile, eggshell mind.
I’m another one that can’t understand how planes fly or big boats don’t sink. I understand the principles and have had it all explained to me. However, my brain immediately places them under magic/witchcraft when I see them in real life.
When I watch these factory programmes about making buttons or bog roll or tinned soup, I just think ‘**** that shit’ what a lot of effort.

Dunno, he seems quite a decent guy on his Strava account. It's been a long time since I had to suffer British TV on a regular basis, though.

And the G-forces at the end of the tip, why it doesn't just rip itself to bits is beyond me.
