Well, everything starts conceptually. It is part of my new
   belief system that 1) everything is is understandable via an
   analogy 2) analogy says how it works completely perfectly from a
   particular zoom level, but to get more precision, to zoom in
   more closely, one most look at other processes (inner or outer
   loops) that modify the initial analogy. 3) #2 doesn't take away
   from #1. They are both equally valid. It's absolute vs relative.
   Same thing, different perspectives. "
