assuming its coastline is given by a (fractal) nowhere differentiable but continuous function...so the expresion for distance integral ds**2=1+(y´)**2 is not valid?..in fact..how do you meassure a fractal distance, surface or volume?.(adsbygoogle = window.adsbygoogle || []).push({});

-Can you assign a metric to define distances if curves are fractals?...could we construct with that metric integrals or derivativess?.
