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?
A cup is essentially a self-contained hole that we pour stuff in, but if I say there’s a hole in my cup you’d know what I meant
From a topology perspective, a cup does not have a hole. A mug does, but its the hole that the handle makes, not the area containing liquid.
