This suggests the reverse is true, that every hole is at minimum a tube.
I’m throwing out all my cups today. I’ll jut drink from my plates.
A straw has one hole that is open to two entrances. Like a single tunnel. We never say that a tunnel has two holes.
I got a T shaped cat tunnel. It’s got two holes. I think. Topology can go suck a lemon
Still one hole unless there’s isolated sections
A straw has 1 hole with two ends… this is dumb
Topologically, people are toroids.
It still has two holes compared to a sphere, and that is our usual frame of reference.
A straw has 1 hole that goes all the way through.
So, infinite holes. Just like a line has infinite points. And, a longer straw has a bigger infinite number of holes.
So do you
This is Crohn’s erasure.
No I got more. My anatomy is special
The disk has two holes separated by a lesser distance
Not if it’s 2D
Holes are arguably 0D.
Idk if you can measure what area a hole takes up it has dimensions doesn’t it?
Sure but THIS hole isn’t 2D because it’s a compressed 3d object.
So, I kinda just woke up from a nap and my still confused mind thought the meme said the straw had four holes.
The colloquial meaning is different from a topological definition. Anything with a through-hole has a hole at each end. It’s an ambiguous question because the answer depends whether you’re referring to a openings in the face of the object (a cylinder in the case of a straw) or the void connecting the surface openings. Perhaps the safest answer is inclusive, so three. I’ve been told I’m not fun at parties.
I love the unabashed sharing of topical knowledge, so you’re welcome to my party.
It’s ok, the people who tell you that weren’t invited to any of the parties either.
You could make infinite indentations in an object with zero holes. That’s a very poor definition for a hope topologically.
I’ll give it a try and get back to you
And yet each indentation could hold something, like cheese or a kitten, so each indentation in functionally different from a smooth surface.
Deforming a shape changes it, thus topology is a special case of specifically ignoring most aspects of a shape.
But more importantly, calling any indentation a “hole” is a case of specifically ignoring the special significance of actual holes. You can’t pass through an indentation.
Guess I can’t dig holes either
Sure you can, they just gotta come out the other side. Otherwise it’s just a fancy divot
ill put a fancy divot in yah dome wit my 9 millie brah
Watch out, we got a badass over here
If you were to tell an average English speaker that you were going to dig an indentation, chances are high that they would misinterpret your meaning.
On the other hand, if you told them that you were going to dig a “blind hole,” I imagine they would have a much better understanding of your meaning and you would still be technically correct.
That’s part of why I try not to talk to average English speakers
Haha fair enough
That’s why we have the compound word “through-hole”.
90% of important parts on living things are pockets and manipulations of surface area, two things completely ignored by topology. Topology is interesting mathematically, and has meaning for traversal and knot problems, but it’s not really useful to describe reality.
but it’s not really useful to describe reality.
This is just not true.
What topology does for people practically, is it allows them to do a rough kind of geometric reasoning in a wide variety of cases. Further, the geometric notions defined via topology subsume many of the more intuitive notions you might already know of from the number line or the plane.
For example, continuity of functions, convergence of sequences, interiors and boundaries of sets, connectedness and many other things are inherently topological notions that any person who has taken a typical calculus sequence should have some intuitive idea of.
One of the biggest difference between actual pure topology and analysis is that analysis is just done in the context of really nice types of topological spaces called metric spaces in which notions of distance are available.
Any time people are using results of calculus in the sciences, under the hood they are using details about topology on R^n.
Topology is immensely useful to describe reality.
That’s why we have a diverse set of words such as “divot,” “indentation,” “pit,” “well,” and so much more!
Topology is a component of the language called “mathematics” we use to understand, describe, and model reality in concrete terms.
But it’s a good definition if you are, say, putting a thing into each indentation. That’s why the two definitions are different.
Right, those wouldn’t be holes.
That’s right you’re not let me help:

We have a pee hole and a poo hole and a mouth hole and a nose hole do really we’ve got a few holes going on there
We have a massive amount of holes in our bodies. Those are just the most major holes. It comes down to what you consider a hole. Is a mouth a hole okay but what about small pours that open and close? Tear ducts would be in the definitely hole category you never think of those.
Sometimes I tell my girlfriend I’m going to use every hole she has, then try to stick it up her nose. Now I realize I can get way more creative.
Oh god we’re just flesh sieves
Beautiful imagery.
I mean no matter how you look at it it’s just the one hole.
In fact, all holes are the same hole.
If you think about it.
I like to think that all our holes are connected in a way
Not like a human centipede though
Tell that to my wife

That’s what my uncle said.
The mother of all holes.
The motherhole if you will.
The Ödipus hole
This, too, is a great bandname.
The Motherhole
I was in a band called that!
We mostly played blues standards and industrial metal and our live shows prominently featured custom inflatables.
So oral and anal are fucking the same hole and pussy is not a real hole.
The pussy’s more of a pit than a hole.
But yes, anal and oral are the same hole.
I can tell you haven’t watch the hole documentary starring Rainier Wolfcastle
Vaginal canal -> cervix -> uterus -> oviducts ->abdominal cavity
I’d say the pussy is a hole.
Yes, but that’s not all, I claim that ALL anal and oral holes are the same hole.
I could agree with you, but first we’d need a species wide human centipede.
Ehh. I’m not sure it’s very constructive to make a topological argument from a debate people usually think about as a linguistic one.
But saying that to make a hole in a sphere, you need to make two holes in the sphere is funny.
Very good observation. Now what about a hollow sphere?
In germany we say alles hat ein Ende nur die Wurst hat zwei
I like to think of this particular example as a sort of reminder that we need to be specific on what grounds we are arguing. Colloquially, and for the sake of practicality, the straw has two holes. You would one hole or the other is in the drink, or clogged. But topologically, yes, there is only one hole.
Except maybe to illustrate the necessity of various disciplines, as this is a maths problem and not a linguistics one.
Arguing the linguistics of this is like arguing over astrology.
How about the digestive system? I’m pretty sure the stomach forms a break
There’s valves before and after the stomach yeah. Are we donuts when those are open or jelly donuts when they’re closed? When am I a cruller or cronut?
duodenum
Nah it doesn’t
Who the fuck thinks that a straw has 2 holes?
How many holes do you got @NachBarcelona@piefed.social?
I think topologically I have only those:
- Mouth to ass (oh yeah)
- Left nostril
- Right nostril
- Left Eustachian tube
- Right Eustachian tube
- Right tear duct
- Left tear duct
No piercings or anything, so that’s it.
Nostrils and mouth are connected, topologically you could therefore have ass to left nostril with the mouth being an own opening!
That said I really really hope you forgot your uthera at least. Which is a curious question back to the subject: is it a topological hole if the opening is only to the insides of the corpus? (Thinking about the reproductive parts of either sex specifically).
I think topologically they don’t count, that’s why I didn’t count the urether/urethra.
Skin pores.
I didnt include them for the same reason I didn’t include the ears or the urinairy tract (they’re not “holes” as in tunnels, topologically speaking), but if your definition differs from mine then you’re right.
They go all the way thru the skin, but not all the way thru the body, so I guess you’re right.
Plus a hole for peeing i hope
Peeings over rated
That’s topologically not a hole, your bladder like you lung is on the outside/surface.
is the ok symbol 👌 a hole?
what about membranes, pores?
The ok symbol is rather temporary but topologically that would count. I wouldn’t count pores or membranes here (I mean by my arbitrary definition).

Am I…Hole?
Well, pretty much every animal is merely a digestive tract with ever more elaborate ways of funneling food in one end and get rid of the waste at the other.
No, you are hansolo, with holes.
