Measurements and time reversal in objective quantum theory /
Measurements and Time Reversal in Objective Quantum Theory is a three-chapter book that begins with a discussion on the fundamentals of conventional quantum theory. The second chapter focuses on the time arrow of quantum theory. It specifically presents a schematized account of the results of an int...
