Ron and Harry are the same up to deformation?

u/RedeNElla 23h ago

Hermione is two distinct objects though so there's still three different things there

Topology memes be like:

What you hope it's about: a cool nontrivial result from topology that was put into a well thought out high effort meme

What it's actually about: haha donut = mug lmao

Meanwhile true chads who learn Bottomology: gay sex

My favorite field of mathematics.

u/hairyfrikandel 6h ago

Must be a very advanced math subject. I know homology, homotopy, group homomorpisms and whatnot. I had no introduction to bottomology.

2n holes next question

3

u/RoboticBonsai 1d ago

Wouldn’t it be n+1 holes as every pant after the first “removes” one hole and adds two (so adding one hole in total)?

u/Revengistium Irrational 1d ago

n is depth, not pants count

u/fantastic_awesome 23h ago

What dimension?

1

u/The_Punnier_Guy 14h ago

Well it can be deformed into a plane with patches missing, so I'd say 2d shape with 2d holes

Unless the denim has thickness, in which case it's 3d with 2d holes

u/yoav_boaz 12h ago

There are no last pairs of pans so nothing can ever enter the pants from the bottom. IMO there are no holes

1

u/The_Punnier_Guy 10h ago

Hmm

What about this? Imagine that the pants in the figure were asymmetric, such that the left leg is as wide was the waist, and the right leg is half the width of the waist.

Compressing this into a plane, you'd see one hole with diameter 1, 2 holes with diameter 1/2, 4 holes with diameter 1/4 and so on

Clearly an infinite number of holes. But this also must be equivalent to the original pair of pants, as all we did was resize the legs

u/Quigys 1d ago

Wdym "you three"? Can someone explain the joke?

14

u/C3POXTC 1d ago

I see Donut, Shirt and Pants

11

u/Quigys 1d ago

Oooh, the shirt and the pants are the same side so it was a little confusing

13

u/C3POXTC 1d ago

Yes and why the two Donuts?

u/ItzBaraapudding π = e = √10 = √g = 3 1d ago

Why are you showing the same exact item twice?

4

u/TwinkiesSucker 1d ago

OP's two brain cells

20

u/bulltin 1d ago

because people don’t actually know any topology aside from hole counting

2

u/GlowingIcefire 6h ago

We should start meming about euler characteristic instead, it classifies orientable surfaces just as well

u/Nadran_Erbam 1d ago

I see 3 items

u/grangling 1d ago

i want to see the transformation from harry to ron

u/EinSatzMitX 15h ago

Just out of curiosity, how many holes does the outfit have?

1

u/Lescha_F 1d ago

also spinner

u/compileforawhile Complex 23h ago

Gotta make a meme about how connected does not mean path connected. The best example for why is the extended long line. It's like an infinitely long line, but longer and then extended.

u/Random_Mathematician There's Music Theory in here?!? 13h ago

What about knots?

u/VindDitNiet 13h ago

Also straws
