 Riemann for AntiDummies Part 12 
  Those magnitudes that are measurable directly by the diameter of the circle, have the first degree of knowability, those measurable by a part of the diameter, have the second degree, and those whose squares are measurable by the diameter, have the third. 
  But to divide it into three parts, that is, to inscribe a triangle in it, requires the generation of a magnitude of the second degree of knowability. 
  But, to divide the circle into five parts, requires the generation of a magnitude of the third degree of knowability, specifically, the golden section.
