摘要

This book is largely based on my doctoral research at Lingnan University, Hong Kong, and my research as an Ernst Mach fellow at the University of Salzburg. It develops a detailed account of the emergence of for all practical purposes (FAPP) continuous, quasi-classical world histories, containing FAPP-continuous macroscopic phenomena, from the discontinuous, stochastic micro dynamics of Tychistic Bohmian Mechanics (TBM). TBM is a non-relativistic quantum theory, recently put forward by Patrick Dürr and me. It results from excising the guiding equation from standard Bohmian Mechanics (BM) and reinterpreting the quantum equilibrium hypothesis as a stochastic guidance law for the random actualization of configurations of Bohmian particles. On TBM, there are no continuous trajectories linking up individual configurations. Instead, individual configurations are actualized independently of each other, carving out the decoherence-induced branching structure of the universal wave function. Yet, by contrast to the Everett interpretation, branches of the universal wave function are not actualized in parallel, i.e. all at the same time. Rather, world branches, on TBM, are actualized sequentially.
