18: Undulation (or Undulatority)
About the title: according to the verb “undulate” is defined as “to move with a wavelike motion”. Also, as used in this book, “Complementarity” is basically a discussion of the verb to “complement”. So, can “Undulatority”, which is hereby defined to mean discussions of wavelike motion, pair with “undulate” in the same way that “complementarity” pairs with “complement”? Why not?…
