'Maps are a human thing. They like to make simplified models in which things are labelled, placed on grids and details are glossed over. I assume it is because their minds are spatial and not mathematical. Things to the human mind are defined by there relation to other things. That is why they need two points to draw straight line, whatever that is. Sincerely, though I don't understand the utility of it, but I don't fight it. The Captain says go to grid space 10-K, and I can discern what he means.'
