Dynamic Root Rectangles Part Two: The Root-Two Rectangle and Design Applications

  • Rachel FletcherEmail author

“Dynamic symmetry” is the name given by Jay Hambidge for the proportioning principle that appears in “root rectangles” where a single incommensurable ratio persists through endless spatial divisions. In Part One of a continuing series [Fletcher 2007], we explored the relative characteristics of root-two, -three, -four, and -five systems of proportion and became familiar with diagonals, reciprocals, complementary areas, and other components. In Part Two we consider the “application of areas” to root-two rectangles and other techniques for composing dynamic space plans.
