    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

    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.

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

        Openings and indentations aren’t the same thing though, are they?

        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 it’s a good definition if you are, say, putting a thing into each indentation. That’s why the two definitions are different.

      That’s right you’re not let me help:

      "The colloquial cloaca meaning is different from a topological Topsy-turvy definition. Anything with a through-hole has a hole at each end^snickering^. It’s an ambiguous GAY question because the answer depends whether you’re referring to a openings in the face of the object^more-snickering^ (a cylinder in the case of a straw)^obviously-unnecessary^ or the void connection the surface openings. Perhaps the safest most radical answer is inclusive, so three. I’ve been told I’m not fun at parties.’

    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.

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

      also, cups and plates are not equal topologically, because a cup has handle with a hole in it, and plate doesn’t

        So we finally realise that the topological notion of “hole” doesnt really capture the natural language concept of a hole.

      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.

    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.

  • I_Has_A_Hat@lemmy.world ⁨1⁩ ⁨day⁩ ago

    I hate this 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.
