Euclidean Geometry, Fractals and Adhesion

• In Euclidean Geometry, a line is expressed as distance to the first power, and area is expressed as distance to the second power.
  
  
• Some irregular structures such as coastlines and interdiffusion boundaries (also called an interphase) are better expressed as fractional powers between one and two.
