a mug cannot function when upside down and yet when you change the arbitrary orientation of a map it can still function the same
you literally missed the point of the _title_ of the article, quite impressive
You can change your entire system of reference and the setup still makes sense. Same with the map.
A drinking mug is a large, cylindrical cup with a handle, typically made of earthenware, used to hold hot beverages like coffee or tea. The orientation relative to gravity is fundamental to the functioning of the mug. It is not arbitrary.
I suspect I don't have this thing the article mentions where I associate the bottoms of things with badness, so I don't get this effect where the bad bottom suddenly becomes the good top if I flip it or myself over. There's just no effect except perhaps getting dizzy.
Yes. Changing your system of reference fixes this too. Just get upside down glasses, gravity now goes "up" and the mug is upside down. Works perfectly. You can live like this if you want.
