Can the Schrödinger dynamics explain measurement?

Abstract The motion of a ball through an appropriate lattice round obstacles models the behavior Brownian particle and can be used to describe measurement on macro system. On another hand, such is chaotic known conjecture asserts that Hamiltonian corresponding quantum system must follow random matrix statistics ensemble. We use represented by in Gaussian unitary ensemble study Schrödinger evolution non-stationary states. For states representing classical system, describes under obtained. general states, Born rule for probability transition between derived. It then shown with macroscopic microscopic systems, provides explanation bodies irreversibility measurement, identifies boundary micro worlds.
