"Think of all the different dynamic laws that might make topological sense, in terms of the propagation of various kinds of particles that are defined as patterns embedded in a graph ... now imagine a new set of vectors that consist of equal amounts of all these dynamic-law vectors, and which are all orthogonal to each other. These vectors represent definite values of a variable that's complementary to the law vectors. Branco calls them law-momenta-which is a bit sloppy, because their not true Lagrangian conjugates, but never mind ... now picture a state vector which has equal components when written as superpositions of the old set, or the new"
