Construct a phase space where every point is center to a circle of radius h, Planck's constant. Particular to such a given point, outside its radius lies conventional phase space and inside, conventional phase space inverted through h - together potentially doubling the effective dimensionality. Their mirror symmetry enables quantum measurement to compactify microscopically the entire range of macroscopic phase space. Quantum mechanics is thus determinable, manifesting as a one-to-one correspondence between a global phase point and its twin, accessible locally by measurement. Concealed within the quantum scale resides the correlate to uncertainty, reciprocal through h: classical dynamics. Inverted phase space and its corresponding wavefunction that predicts a spectrum of virtual particles are direct consequences of the conventional quantum wavefunction, de Broglie's and Einstein's postulates, and the linearity of Schroedinger's equation (article #1). The dual wavefunctions interfere to generate familiar particles and complete the phase space landscape with the extra information needed to coincide quantum with classical causality.
