Got it, a CD has 2 holes as well.
What the heck is a CD?

At step 4 it is not a straw anymore…
at step 2 it’s not a staw anymore, that’s a narrow funnel.
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 connection the surface openings. Perhaps the safest answer is inclusive, so three. I’ve been told I’m not fun at parties.
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.
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.
You seem to not be getting that words can have multiple (even if related) meanings. When some science or other discipline takes a common word and defines it really precisely for their purposes, that doesn’t change the definition of the common word for all usages and mandate that all lay people use it only with that discipline’s more precise definition.
It’s ok, the people who tell you that weren’t invited to any of the parties either.
That’s right you’re not let me help:

Great now I need a new folder.
hehe kinky
A straw has 1 hole that goes all the way through.
The disk has two holes separated by a lesser distance
Not if it’s 2D
Sure but THIS hole isn’t 2D because it’s a compressed 3d object.
Holes are arguably 0D.
Idk if you can measure what area a hole takes up it has dimensions doesn’t it?
I’m being tongue in cheek of course and this is more a matter of philosophy and ontology than math and physics, but one could claim that the hole itself does not exist, it is the absence of matter, so what you are measuring is not the hole but rather the distance between any two points of matter. Otherwise one could point to nothing and claim that it is a hole of any size (like pointing to the sky and simply defining some part of it a hole of a certain size- it would effectively be a meaningless proposition in some sense).
But again, it is truly just silly semantics. :)
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.
That’s what my uncle said.
The mother of all holes.
The motherhole if you will.
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.
The Ödipus hole
Tell that to my wife

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.
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.
I was making a minnow net to catch baitfish for my son. To make a cone you need a half circle of material out of mesh.
Now in a 2D world the where there is no thickness this would be correct, if material can be added to fill gaps.
In a 3D world, any round object with a hole and some thickness could be a straw. A washer is a straw by this logic
if you food poisoning you will be exiting out of both holes.
Fun fact: the alimentary canal is one long tube, like a straw. At one end of the alimentary canal is your mouth. At the other end is your asshole.

Who the fuck thinks that a straw has 2 holes?
How many holes do you got @[email protected]?
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.
you are forgetting the oropharynx. nasal area to the throat.
That’s included in both nostrils (they both end up there).
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).
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.
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.

If a flat disc has no holes, how many holes does the surface of a sphere have?
A straw has zero holes. It’s just a flat piece of plastic wrapped around and attached to itself. Ain’t nobody drilling holes through plastic to make straws.
Try that argument with your local topologist
Vsauce, Michael here.
So, I kinda just woke up from a nap and my still confused mind thought the meme said the straw had four holes.
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.
Fields dont need to be that isolated. In the end its arbitrary, so why not accept arguments of all perspectives?
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.
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?
All spheres are hollow (mathematically)
is x²+y²+z²<=r² not considered a sphere then?
Technically, the digestive system (i.e., the full gastro intestinal tract) is considered as part of the “outside” of the body, acting as an external surface similar to the skin. The space that an object can travel through without crossing a cell membrane or entering blood or tissue is called “lumen”. So the same intuition as in the meme actually holds true here, too.
