No, since you have a nose. Topologically, people have 3 holes.

[-] chuckleslord@lemmy.world 18 points 1 month ago

7, if the cut-off is 60 microns (tear ducts). Smaller than that, we're essentially Swiss cheese.

Tbh, I was kinda hoping for someone with better biology knowledge than me to correct me. Thanks.

What are the the 7?

[-] coffee_whatever@lemmy.world 7 points 1 month ago* (last edited 1 month ago)

Important note, if you take a straw that separates into two split straws (kinda in a "Y" shape) that from a topological point of view is two holes, because one is for one of these paths, and the other is an extruded hole on the side of the first path. In topology you can't break or mend material, but you can pull, stretch, squeeze and move it all you want. So you can move one of the split straw "legs" to the bottom of the whole straw, getting a shape similar to a "V", it would look pretty much like a pair of pants. And topologically speaking it would be exactly the same. So... One straight hole for your mouth all the way down to your anus. Another two are there for your nostrils, that's 3 already. The rest are for your tear ducts, which have two holes on the edge of your eye, (so four in total) which merge and then connect to your nose.

So a human, from a topological perspective, is just a seven holed doughnut. Also Vsauce made a great video about that, with pretty great animations.

I am well aware that people have three topological holes. Matter of fact, I proved that years ago.

In this case, I only referred to one topological hole, from mouth to anus.

I never mentioned the nose, nor was that part of the topic in question.

Yum.

why is the nose only one hole?

[-] accideath@lemmy.world 6 points 1 month ago

Nose is two. Your butt isn’t one. Or rather, your mouth and nostrils would be the entrance and your butt is the combined exit of those three holes. If you don’t count the nostrils, you only have one hole. A hole always goes through something, otherwise it’s just a cavity. And also, holes only count from one side. Your butt and mouth are the same hole, just from different ends.

Kissing with open mouths creates a hole from one butthole to another.

[-] match@pawb.social 2 points 1 month ago

oh! but then why is it three holes and not nostril-to-mouth as a hole and other-nostril-to-butt as another hole, or some other combination

Butthole:

That is 3 holes in total because you can "connect" any opening with 3 different one's.

thank you!!

[-] over_clox@lemmy.world 2 points 1 month ago

Nose is only one hole, topologically speaking. You can run a string from one nostril to the other.

One topological hole.

[-] chuckleslord@lemmy.world 5 points 1 month ago

No, all 7 holes (nostrils, mouth, tear ducts) have a common cavity, so they're 7 holes not one.

This is a Wendy's. We only offer nostrils, mouths and anuses here.

[-] over_clox@lemmy.world 2 points 1 month ago

Nose is only one hole homie, runs from one nostril to the other. It takes the mouth to add a secondary orifilce. And it takes the anus to add a third orifice.

Topology for ya.

[-] accideath@lemmy.world 3 points 1 month ago

Doesn’t matter which way you turn it, the result is the same. As you count it, your first hole is nostril to nostril. I count mouth to anus as hole one and then add the left and right nostrils as secondary and tertiary orifices. Having a nose ads two holes to the total count. If you had no nose, you‘d have one hole, if you only had a nose, you’d also only have one hole.
