Seem pretty cut and dried to me. Time to bomb Winnipeg!

Well I know people who go for this shit in earnest, so it’s good satire.
Reddithas a sub called r/peopleliveincities, I’m sure they’d be happy to accept this one as well.I’d argue that’s why it’s not good satire. this just goes straight into another conspiracy theory now. satire doesn’t really work when it straight up contributes to what it’s supposed to be satirizing.
that’s like satirizing the US culture by shooting up a school.

Are you okay?
Fact checking satire makes for even better satire.
Guys, I went to the center of the circle, and there was a completely normal looking tree there. Maybe too normal. What could it mean?
We need to dig deeper and get to the root of this.
I dug it up, and found some bugs, worms and roots. Some kind of code?
I knew it! The libs bugged our phones to infect us with their brain worm! Smash your phone and chuck it in a lake!
Guys, look at this mushroom! All these little frills!
What were we doing?
Put that down that’s a deep state mushroom!
The mushrooms are safe from intervention, for there is no government above the Council of Fungi. They are the real Illuminati, spread across the world beneath our feet. A collective unconscious with a singular, defiant will.
Now that is a BIG mushroom!
If you start digging there and go all the way to the other side, you will end up in China! Check mate libtards. /s
I can’t beleave you made that pun
Ceenote is branching out into comedy.
I connected the three trees at the middle and they made a triangle!!! How deep does this thing go?’
A triangle? Oh no…
Why is nobody mentioning that any point you choose just happens to be in an EXACT STRAIGHT LINE from the others!? And this just happened by chance? I’ve got some ocean-front property in Arizona I’d love to sell you.
co-linear points can also be on a circumference, if you don’t mind infinite radius
I was about to ask whether you can have three colinear points on a sphere, but then I remembered that the Earth is flat.
Which brings me to another question. What does a circle on a Mercator projection looks like on a sphere?
You can test this at home. Draw a circle on a paper, wrap it around a ball.
If you want the edge cases, draw the circle on a sheet of rubber (or maybe a plastic bag?) and stretch it over a ball.
Non-euclidean planes say what?
Hold up! You can even make a triangle out of those 3 points! Illerminaty confirmed.
Aka “the strongest shape.” Think about it.
The next one will be in the Arctic.
Also didn’t know we were calling this the UWU shooting.
Winnipeg was the shooter! I knew it!
Winnipeg was the inspiration for Winnie the PoohWinnie the Pooh is the code for Xi Jinping
China was behind the grassy knoll
That’s a big grassy knoll.
It’s always fucking Winnipeg. People need to find a new punchline…
Winnipeg sounds like some kind of bear furry porn.
Could be a coincidence. Only way we’re going to know is if we occupy Winnipeg.
For at least 5 months of the year no one wants to occupy Winnipeg. That value increases slightly for the other 7 months.
Be nice to Canada, they have the worst neighbors
Fucking Alaskans, man.
Can you do that for any 3 points on a surface?
it definitely works for planes and spheres. my intuition says it wouldn’t work on all surfaces though, and in particular would probably break down around saddle points.
Flat earth confirmed
Oh right, this only works in 2D. You would need to have a sphere. Checkmate atheists
So long as they’re not in a straight line, yeah (as it says as at the bottom of the post).
Whoa whoa whoa…
There is a bottom of the post?
I wonder what size the circle would be if you took in to account the earth’s curvature.
Are there any map projections that allow for accurate projection of circles across arbitrary points?
Stereographic projection is the one (and only) thatballows that. You can draw any circle (or a straight line) on a stereographic map and it will remain a circle on the globe.
https://en.wikipedia.org/wiki/Stereographic_map_projection#Properties
All map projections are arbitrary. The only way to do this is on a globe.
Different projections preserve different properties. From memory there are ones that leave circles circular, so would allow this.
Edit: It’s stereographic projection that maps circles to circles.
Looking at the stereographic projection, there is a longer distance between points the father you get from the center of the map. Although the latitude lines remain circular in a polar projection, the map scales to avoid distortion father from the constant growth of the map once you leave the projected hemisphere. The northern hemisphere in an artic projection still must distort, making geometry a mess.
Goode homolosine projection is closer to keeping that distortion down, but all maps are an estimate due to the way a 3d curve is translated to a flat surface.
All that said, and I know I’m being pedantic, you could come really close by calculating the center of the circle in a sphere, then projecting the map stereographically from the center. That specific projection would come the closest, given the irregular shape of the Earth.
There are projections where infinitesimal circles stay circles, e.g. our dear Mercator projection, but that doesn’t hold for finite sized circles, i.e. circles would still be distorted in north-south direction.
Tissot indicatrixThat’s a general metric holding for lots of projections. I think the specific projection that works for finite sized circles is stereographic projection.
On a stereographic map you should be able to draw a circle that stays a perfect circle (“small circle”) on a globe.In addition, in its spherical form, the stereographic projection is the only map projection that renders all small circles as circles.
By small circles they mean circles on a sphere that are not an equator (great circle), not infinitessimally small circles. So basically they just mean circles.

This only applies to the circles perpendicular to the axis of projection, i.e. usually the circles of latitude (parallels), though. The Tissot indicatrices still show increasing sizes of the circles from the center of the map to its outside. Thus, any circle that isn’t coaxial with the parallels is distorted on the map.There is no qualifier on wikipedia and I do remember seeing some neat geometry tricks you can do with the property long ago.
The Tissot thing to me looks like a visualization for the jacobian, so the factor by which the area at that point is scaled, plus the gradient.
The circles in the stereographic projection are scaled, they are essentially pulled outwards, when further away from the center. This matches an increasing jacobian. But they stay circular, the stretching happens in the right way for that to hold true.If you wait a bit I’ll see if I can find some further things relying on this property, or at least stating it more unambiguously.
The Tissot thing to me looks like a visualization for the jacobian, so the factor by which the area at that point is scaled, plus the gradient.
Essentially, the tissot indicatrices are a visualization of the eigenvalues and eigenvectors of the projection in any point. So, in 2d, the areas of these ellipses correspond to the Jacobi determinant, the product of the two eigenvalues of the Jacobian at that point.
The circles in the stereographic projection are scaled, they are essentially pulled outwards, when further away from the center. This matches an increasing jacobian.
Exactly. The Jacobi determinant increases in radial direction (longitudinal on the globe).
But they stay circular, the stretching happens in the right way for that to hold true.
If you draw a circle on a globe, that is not coaxial to the parallels and apply the projection, the radius of said circle becomes elongated in outward direction in the same way the circles of the Tissot indicatrices increase in size.
Or in other words, any slice oncrement of the circle along a fixed degree of latitude changes in size depending on the value of the Jacobi determinant at that degree of latitude.
Thus, the circle on the globe becomes somehow like a rounded triangle on the map.Edit: That shifts only the center of the mapped circle towards the outside of the original, but the circle remains a circle.
If you drew in on a globe, it would look deformed in this projection. I think the radius wouldn’t change, but it would look “wider” towards the north
That theorem only applies 2d from my understanding
I never thought about it, but now I’m gonna have some fun with this.
The center of that circle is the Northwest Angle, and it’s populated by turmpers. It was created by a “survey error”. This tells me that Canada killed JFK because they knew Turmp would happen if they did. This was a Canadian attack all along.
I got in trouble in my friend group meme chat for drawing a Star of David connecting the points in this meme
That’s almost the plot of the rdj Sherlock Holmes movie. Just, you know, different star.
Fuck is this not satire?
Don’t take all this stuff too seriously, most of it is either performative content revenue farming or manipulation of public opinion by some actor. This ticks all boxes, could be anything; a person honestly that dense or deep into conspiracy theories isn’t even the most likely one. Unfortunately neither is satire.
look at the body of the post
In my defense, it was 3 AM.
Shit I’m stupid.
