    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’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. :)

              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?

        I think topologically I have only those:

        1. Mouth to ass (oh yeah)
        2. Left nostril
        3. Right nostril
        4. Left Eustachian tube
        5. Right Eustachian tube
        6. Right tear duct
        7. 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 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.

          Christmas is just another form of control, from the matrix.

          it pushes massive consumerism and the idea to kids must do as told to be “nice,” cause we can watch them all the time like a cia state.

          Is that less forbidden?

    This suggests the reverse is true, that every hole is at minimum a tube.

    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.

      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.

            is x²+y²+z²<=r² not considered a sphere then?

              Nope. That’s a ball. A closed ball to be precise. “Sphere” refers specifically to the “=” part.

    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.

        Depends whether or not you consider the fastening of a surface to itself to be a real change to the topology.

    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.
