It is one of the great debates albeit a schism in twentieth century physics arose over the interpretation of the quantum phenomenon. On the one hand was the so called 'Copenhagen School' with Neils Bohr as its high priest and on the other were the objective realists under the leadership of Albert Einstein. The former stressed the role of the nature of measurement as the source of the quantum phenomenon, while the latter attributed it to some underlying 'Objective cause'. The attempt of this book is to present a self consistent treatment of quantum phenomenon using one of the most promising 'Objective realist' approach, namely, the stochastic formulation of quantum mechanics which a whole school of physicists who were and are votaries to the objective realist world view, have tried to develop over the last several decades. There are many facets of this scheme that are rich areas for further pursuit by young and enthusiastic physicists, and this book, hopefully, will induce many to pursue this vision.
