Two people kissing make a single contunous tube going from one anus to the other

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.

[–] untorquer@lemmy.world 13 points 5 hours ago (2 children)

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.

[–] CheesyFox 1 points 33 minutes ago (2 children)

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

[–] titanicx@lemmy.zip 1 points 8 minutes ago

Not all cups have that. I would consider that more a mug.

welcome to topology

[–] Rhoeri@piefed.world 22 points 10 hours ago (1 children)

A straw has one hole that is open to two entrances. Like a single tunnel. We never say that a tunnel has two holes.

[–] HeyThisIsntTheYMCA@lemmy.world 6 points 6 hours ago (2 children)

I got a T shaped cat tunnel. It's got two holes. I think. Topology can go suck a lemon

[–] Rhoeri@piefed.world 1 points 1 hour ago

Which is why I said SINGLE tunnel.

[–] Natanael@infosec.pub 1 points 3 hours ago

Still one hole unless there's isolated sections

[–] Earthman_Jim@lemmy.zip 12 points 11 hours ago

A straw has 1 hole with two ends... this is dumb

[–] gedaliyah@lemmy.world 14 points 13 hours ago (1 children)

Topologically, people are toroids.

[–] Kolanaki@pawb.social 43 points 18 hours ago (3 children)

A straw has 1 hole that goes all the way through.

[–] anzo@programming.dev 1 points 2 hours ago

So, infinite holes. Just like a line has infinite points. And, a longer straw has a bigger infinite number of holes.

This is Crohn's erasure.

[–] HeyThisIsntTheYMCA@lemmy.world 1 points 6 hours ago

No I got more. My anatomy is special

[–] DragonTypeWyvern@midwest.social 13 points 18 hours ago (4 children)

The disk has two holes separated by a lesser distance

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.

[–] Akasazh@lemmy.world 1 points 3 hours ago

I love the unabashed sharing of topical knowledge, so you're welcome to my party.

So, I kinda just woke up from a nap and my still confused mind thought the meme said the straw had four holes.

[–] someacnt@sh.itjust.works 4 points 12 hours ago* (last edited 12 hours ago)

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

[–] tomiant@piefed.social 36 points 19 hours ago (9 children)

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.

[–] RagingRobot@lemmy.world 2 points 9 hours ago

I like to think that all our holes are connected in a way

Not like a human centipede though

That's what my uncle said.

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

[–] CovfefeKills@lemmy.world 2 points 8 hours ago* (last edited 8 hours ago) (2 children)

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.

[–] SkyezOpen@lemmy.world 3 points 6 hours ago (1 children)

Sometimes I tell my girlfriend I'm going to use every hole she has, then try to stick it up her nose. Now I realize I can get way more creative.

[–] comrade19@lemmy.world 4 points 7 hours ago (1 children)

Oh god we're just flesh sieves

[–] CovfefeKills@lemmy.world 1 points 7 hours ago

Beautiful imagery.

[–] halvar@lemy.lol 15 points 18 hours ago (4 children)

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.

[–] stevedice@sh.itjust.works 3 points 7 hours ago (1 children)

But saying that to make a hole in a sphere, you need to make two holes in the sphere is funny.

[–] halvar@lemy.lol 1 points 3 hours ago

Very good observation. Now what about a hollow sphere?

[–] knatschus@discuss.tchncs.de 2 points 11 hours ago

In germany we say alles hat ein Ende nur die Wurst hat zwei

[–] Derpenheim@lemmy.zip 7 points 17 hours ago

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.

How about the digestive system? I'm pretty sure the stomach forms a break

[–] HeyThisIsntTheYMCA@lemmy.world 3 points 6 hours ago

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?

Who the fuck thinks that a straw has 2 holes?
