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?
I disagree. A rubber band and a donut do not have an ‘in’ and ‘out’.
A straw does? What are you, the straw police?
Stick your finger through a donut, does it go in one side and out the other?
Giggidy.
A straw’s “in” and “out” are completely arbitrary. You can flip a straw either way and it’d still work.
Anything with a hole through it that isn’t perfectly 2D could have a “in” and “out” side. Your rubber band your doughnut only don’t have one because nobody ever thought to define one.
