Oh let's get pedantic!

The curved edges technically have infinite "side".

[–] PeriodicallyPedantic@lemmy.ca 7 points 1 day ago (1 children)

Hey, that's my job!

Also I don't think that's technically the technical classification. I think that sidedness is an attribute that simply doesnt apply to curves.
You can approximate curves with some number of sides, and the approximation gets more accurate as the number approaches infinity, but it doesn't actually have the infinite sides.

Very cool! I'm always happy to learn something new!

[–] PeriodicallyPedantic@lemmy.ca 2 points 1 day ago* (last edited 1 day ago) (1 children)

I mean, I'm just pedantic; double check with a mathematician, to be sure lol

[–] YiddishMcSquidish@lemmy.today 1 points 1 day ago (1 children)

I'm genuinely curious, what is your job that requires arithmetic?

[–] PeriodicallyPedantic@lemmy.ca 2 points 1 day ago (1 children)

I feel like most jobs require arithmetic.
But it is not my career to be a pedant, just my role in life 😜

....and a square has four interior 90 degree angles.

...and based on the infinite number of sides for a curved line aspect, the "90 degree" angles would all be +/- the limit as it approaches zero, so never truly 90 degrees but always an infinite fraction away.

[–] jwmgregory@lemmy.dbzer0.com 2 points 1 day ago

the angles are interior if you go into the scary world of high level maths and their weird fucking geometries.

this is a square, from a certain point of view

[–] olafurp@lemmy.world 5 points 2 days ago (2 children)

Yeah, we gonna need more rigor on this one.

"A square is a shape made up of four equally long lines a, b, c, d where a is perpendicular to c and d and parallel to b. Each of these lines meet exactly two other lines at it's ends."

I'm not a mathematician so there might an odd case somewhere in there. Maybe it has to be confined to a shared plane?

[–] sneezycat@sopuli.xyz 2 points 2 days ago (2 children)

Lines are infinitely long... do you mean line segments?

Wikipedia has a good enough definition: "It has four straight sides of equal length and four equal angles." Nice and simple.

[–] olafurp@lemmy.world 4 points 1 day ago

Pentagon fits that definition also since it doesn't specify "it has four and only four" sides

[–] hansolo@lemmy.today 1 points 2 days ago (1 children)

So you're saying this is the outline of a square in the astral plane? Because it sounds like you're saying this is a square in the astral plane.

[–] olafurp@lemmy.world 2 points 1 day ago

No, just a 2d plane

[–] YiddishMcSquidish@lemmy.today 5 points 2 days ago (1 children)

Someone knows more calculus than they are letting on...

[–] hansolo@lemmy.today 4 points 2 days ago (1 children)

Hey, I failed the highest level of calculus possible. Twice.

I'll have you know that I passed the two lowest levels of calculus required for my degree. So you know, I'm something of an expert.

[–] danhab99@programming.dev 11 points 2 days ago (1 children)

Not if this square is a projection of a curved surface

[–] YiddishMcSquidish@lemmy.today 5 points 2 days ago (1 children)

If it is a projection, then there are more than two curved sides, which also begs credence to the interpretability of the angles they intersect.

[–] danhab99@programming.dev 3 points 2 days ago (2 children)

Well angles between 3 points are always going to be angles. If your choose a different configuration of dimensional parameters you can effectively project a square from the 2D plane into this exact shape, then logically the angles would follow.

[–] YiddishMcSquidish@lemmy.today 3 points 2 days ago

You lost me at 3 points. Could you dumb it down a bit?

Yo bro let's downscale everything to 2D then upscale it to infinity or something, everything is possible when you project to this demonic crystal justttt this way /s
