At work we somehow landed on the topic of how many holes a human has, which then evolved into a heated discussion on the classic question of how many holes does a straw have.
I think it’s two, but some people are convinced that it’s one, which I just don’t understand. What are your thoughts?
So what you are saying is, if I dig a hole that doesn’t go anywhere, then that’s not really a hole?
In topology, yes. It must go through to count.
That’s fascinating. So most of what I would call “holes” are what, in topographical terms, hollows? Depressions?
I don’t even know if they have a name for that since it can simply be undone by stretching the object, which is allowed under topological rules.
Topologically, yes. Coincidentally, “Hole to Nowhere” is the best Talking Heads parody album.
Heh I will have to check that out!
