Austin-

In your diagram, I think we see the essence of the difference in 
expression between you and Martin.

The key element being the smallest unit.

It sounds to me as though you stand for the proposition that the 
smallest measurement is range comes from the existence of a "small 
unit of change" whereas it sounds as though Martin believes that the 
unit of change derives from ones ability to MEASURE change...with the 
implication that the regress of change are really infinite.

Certainly with the quality of printers most of us are using, the size 
of the unit of steps must be measurable in some fashion (which tends 
to favor Austin's case) yet the measurements mentioned here, at 
least, seem to tend to show something approaching infinite (or more 
than can be measured?).

Have I missed something?
