Their cause: a question from a richer structural level posed in the vocabulary of a simpler one, i.e. level incompleteness.\n  This monograph makes the levels explicit, constructing a canonical tower of nine categorical levels from stoichiometry through thermochemistry, equilibrium, kinetics, electron-pushing mechanisms, stereochemistry, potential energy surfaces, and electronic structure to all-particle quantum mechanics.
