But this is a different concept I believe. What I call direction is what you ussually refer to as "degree of freedom" (DOF). I believe that a dimension has to directions (degrees of freedom), but doesn't "go" one way or another, I mean, how can a dimension "move"? NO, objects move in dimensions, but not dimensions. If dimensions would move, or have a direction, then it would mean that there are dimensions for the dimensions, and this owul dbe very confusing...
