A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
This is a science community. We use the Dawkins definition of meme.
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.
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.
It’s ok, the people who tell you that weren’t invited to any of the parties either.
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.
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.
Two people kissing make a single continous tube going from one anus to the other
Great now I need a new folder.
hehe kinky
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:
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.
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
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.
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.
Vsauce, Michael here.
A straw has 1 hole with two ends... this is dumb
So, I kinda just woke up from a nap and my still confused mind thought the meme said the straw had four holes.
Got it, a CD has 2 holes as well.
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.
that meme format makes me feel old... I used to see it in like 2008 👴
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.
How about the digestive system? I'm pretty sure the stomach forms a break
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
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
