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.
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.
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 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.
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.
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.

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 can you measure something that doesn't exist? Can the absence of something be something in and of itself? Is it the hole you are measuring, or the object around the hole?
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 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.
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.
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.
You're right! But from what I could find, the fake version started circulating less than a year after the original, so I honestly can't remember which one I've seen more over the years. I didn't even notice there were multiple versions lol.
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.
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.
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?
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.
No, that's a punctured disk, you're thinking of a torus.
Edit: After dusting off my old-ass-hasn't-been-in-uni-for-10-years-brain, I've concluded the straw shown in the image is NOT a punctured disk, it's a closed annulus. It's still not a coffee mug and you're still thinking of a torus but I don't wanna go around spreading wrong math.
I hate this faulty logic. Of course there are two holes. Look, plug one end and do the unfold method in the comic again so instead of one hole in the center, it's just a solid disk. Does that mean if the straw is plugged at one end there are zero holes? Of course not.

You could make infinite indentations in an object with zero holes. That's a very poor definition for a hope topologically.

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.

at step 2 it's not a staw anymore, that's a narrow funnel.

It still has two holes compared to a sphere, and that is our usual frame of reference.

Nah, there’s like 11 to 14 macroscopic holes in my body. You just can’t get a dick in most of them.

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.

After it's flat it's ready to be made into a coffee cup

No, that's a punctured disk, you're thinking of a torus.
Edit: After dusting off my old-ass-hasn't-been-in-uni-for-10-years-brain, I've concluded the straw shown in the image is NOT a punctured disk, it's a closed annulus. It's still not a coffee mug and you're still thinking of a torus but I don't wanna go around spreading wrong math.

I hate this faulty logic. Of course there are two holes. Look, plug one end and do the unfold method in the comic again so instead of one hole in the center, it's just a solid disk. Does that mean if the straw is plugged at one end there are zero holes? Of course not.

I mean, you plugged the hole..

When companies drill for oil, are they not drilling holes because only one end is open?
Hule@lemmy.world · 4 pts · 235d
They drill to get through.
