Heisenberg Uncertainty, Sign-Dual Pair Geometry, and the Emergence of Two-Body Quantum Dynamics Research Draft Heisenberg Uncertainty, Sign-Dual Pair Geometry, and the Emergence of Two-Body Quantum Dynamics A self-published paper that treats the paired system—not the isolated marginal particle—as the primary object, then threads that structure through uncertainty, curvature, Hamiltonian dynamics,…
