You must be pretty long, if you reach both ends of the spectrum.

Fucking A indeed!

Or the spectrum is actually a donut

[-] CrazyLikeGollum@lemmy.world 3 points 4 months ago

Fun fact: humans are geometrically a donut.

I'm sure most people have more (topological) holes than one

Both nostrils, for example

[-] CrazyLikeGollum@lemmy.world 3 points 4 months ago

The nostrils are connected to the throat through the sinuses as are the ear canals. Topologically making them all part of the same mouth-anus throughole.

Not true, topolgically the route

left nostril -> sinus -> right nostril

is another hole. So is

any nostril -> sinus -> mouth.

ears have the eardrum, so they don't count.

For the more formal definitions of topological holes, look up Betti numbers, I think there's a VSauce video about it? For humans, the number of holes is at least 3 (but I'm sure I'm missing many more holes). Unless you're missing the entire septum.
