Re: Tenkan and Centrifugal Force
When I tenkan, I think that the initial movement (kai ten maybe) is going have some forces acting inside my body acting towards center, and as I complete that rotational movement (stepping back so to speak) that movement is going to have some forces acting inside my body going away from center (my foot resulting in stepping back away from my center for one).
I totally agree that semantics are important if they are actually causing a misunderstanding as opposed to using them to put someone down just to try to establish/assert dominance. Everyone makes mistakes. I wouldn't consider the usage of that term a mistake since everyone knew what was meant - which is the purpose of having a common language. Some people consistantly make the mistake of trying to put themselves on pedastols at the expense of others. The bottomline is that no one has rank in a forum.
