Who wants to do geometry constructions?
No, well we’re gonna anyway.
A bit of backstory. Way, way back in the late aughts I had a crappy phone support job and watched a lot of anime. Fullmetal Alchemist was a favorite of mine, and I’d often doodle the various alchemy seals from the show while listening to customers blather on. In the course of my drawing I became intrigued by one of the shapes, and I posed myself a brain teaser that took me several years of poking at during bored moments until I finally solved it. Now I pose it to you:
Select a point, then create a circle centered on that point. Now, using only straightedge and compass, construct a 3x3 square grid so that it intersects with that circle thusly:
This is real easy if you start with the grid, but deceptively hard if you start with the circle. Until you know the trick anyway.
Good luck, math nerds!
If you'd like to work on a solution and post it, this site has a nice tool for drawing geometrics.
Solutions
Clipse: A coordinate system? Madness! And the proof.
Hirocon: A trisection and projection.
Surfpossum: A circle and a quartered inscribed square.
My solution:
No, well we’re gonna anyway.

Really don't look if you're interested in solving, I'd like to see if anyone else comes up with it.
life's a game that you're bound to lose / like using a hammer to pound in screws
fuck up once and you break your thumb / if you're happy at all then you're god damn dumb
that's right we're on a fucked up cruise / God is dead but at least we have booze
bad things happen, no one knows why / the sun burns out and everyone dies

What a ahitty, bodunk league.
I honestly think you're seeing racism where there is actually misanthropy in those people who were like "take the risk and tranq the gorilla."
I hilarious seeing something so widespread and popular on the Internet that companies can't appropriate for profit
there's no way you could have Brands Saying Harambae
A bunch of toddlers could beat Dundee FC or whatever is the name of that cursed team
No, it's a mathematical construct
"We believe in the people and their 'wisdom' as if there was some special secret entrance to knowledge that barred to anyone who had ever learned anything." - Friedrich Nietzsche
on the subject, everyone should check out the numberphile vids by this guy.
(unfortunatly the sound tracking is off in this vid but it is the best so just listen)
Thus it is a quantum construct.
It's unfortunate people have been enjoying Kellog's for the last century or so...
It's not
but that's also now how you use those words
everyone stop it

@spool32
stopping it is impossible because time is a circular construct
we should just ban kids under 10 from going out in public
ayn rand taught me that reason can be man's only sovereign, selfishness his primary virtue
aaaaaaaaaaaaaah
so many things wrong with the math here
1) a limit can never equal infinity. If a limit approaches infinity (technically: diverges) then the limit does not exist
2) Even if you ignore #1 that limit wouldn't exist because it approaches either +infinity or -infinity depending on which direction you approach 8 from. And the definition of a limit for real numbers requires that the limit be the same regardless of direction.
yeah but in standard calc you totally write limits as if they = infinity or -infinity
well, no you can't. In common english you can. It is usually understood as a sloppy shorthand for "limit does not exist". But in no form of rigorous mathematics is that acceptable.
are they? it strikes me more as someone weary after years of being exposed to game communities for mmos and the like knowing that most players don't know what the fuck they want or even if they did, they want something that would be bad for them, and having to answer questions along the vein "why don't you do this" again and again
Since coming back to wow, I have found that it is the current popular meme in general chat, and yep, that is about the appropriate quality.
They aren't wrong though.
Since it is possible there are infinite solutions, but I think mine is fairly elegant.
