6.2 Oh Mandy! You gave us your set without taking

We spend our days mentally measuring two metres.  When we need something more accurate, we use a ruler or a tape measurer.  Strangely, when we measure the length of our coastline, we have to take into account the length of the "ruler".  This observation takes us into a world of fractals, butterfly wings and measuring weather patterns and climates.  Caveats anyone?
