What if we just assume current flows from negative to positive?
Negatrons and Positrons would have been so much better names

Title text: Sure, we could stop dictators and pandemics, but we could also make the signs on every damn diagram make sense.
Well obviously the robots would be good instead of evil that way
Unrelated, but what is the origin of this image? I feel like I’ve seen it often over the years and don’t know where it came from originally.
It looks like a super genetic stock image, and I always assumed that’s what it is.
What, and live with negativity at the heart of every atom?
Benjamin Franklin’s ultimate prank
this would also be society if counterclockwise and clockwise were swapped. it’s the universal way to talk about 2d rotations but pretty much nothing (except a clock) ends up turning clockwise. it didn’t have to be this way
that’s not arbitrary - the hour hand of a clock mimics the shadow of a sundial.
it makes sense, in the northern hemisphere, where 90% of people live.
Ummm… Have you ever used a screw? Bottle cap? “Right tighty, lefty loosey”? A car wheel when going forward? Literally 99% of things tighten clockwise.
You’re the person people have to say “no, your other left” a lot to, aren’t ya?
Also 99% of things loosen anticlockwise. So why preffer tighten over loosen?
i don’t ever use bottle caps or cars. but in the case of screws (and bottle caps), the choice to make them tighten clockwise and loosen counter clockwise is entirely arbitrary.
my main point is that i think it’s confusing that clockwise is negatively oriented and counterclockwise is positively oriented (in the mathematical sense). and the mathematical definition of orientation is ultimately dependent on trigonometry. and it just feels wrong that clocks are negatively oriented.

no.
Just wanna say, a car tire moves a different direction based on your perspective.
If you’re looking at the driver side of the car, the tires move counterclockwise, whereas if you’re looking at the other side, the tires appear to rotate the other way.
Perspective changes a lot of things, it’s pretty cool.
I thought you messed up the sides but then realised driver side is not the same on every country
You can get a clock that is set up counter clockwise to mess with people

I recognise the grandstand from the Marylebone Cricket Club, but they tore down the rest of the stadium. I guess that’s a good thing?
