This is suddenly an I interesting question, given these responses. I especially like the answers which relate one coordinate system to another system, either in mathematics or other computer software. I wonder if there are any hardware solutions choosing one coordinate system over another…reminds me of photography in a darkroom. A corner is cut off of the film so you can orient the film emulsion in the dark. In that case it’s useful to choose a system, though any orientation would suffice. This discussion gives me the idea that if your curriculum crosses over to require different coordinate systems, then a new lesson might emerge about how different models are used in different contexts. Like choosing Imperial or Metric, it’s part convention and part utility.
