If scale is a physical continuum, then shouldn’t there be situations we must use a cross-scale approach?  What sorts of problems might require such a cross-scale approach? Consider attempting to determine the combined velocity of a small object (on earth) […]

We do consider scale as part of our reality.  We even consider it to be a continuum of reality, if not part of our 3-D model of space.  However, we experience objects as appearing differently at different scales.  Our bodies […]

To understand how basic this concept of scale is, consider specifying a point in space.  We need a reference system for this, traditionally thought of as a three-dimensional set of axes.  One axis exists for each dimension and locating a […]
