Abstract: Abstract To begin with, some of the conundrums concerning Quantum Mechanics and its interpretation(s) are recalled. Subsequently, a sketch of the “ETH-Approach to Quantum Mechanics” is presented. This approach yields a logically coherent quantum theory of “events” featured by isolated physical systems and of direct or projective measurements of physical quantities, without the need to invoke “observers.” It enables one to determine the stochastic time evolution of states of physical systems. We also briefly comment on the quantum theory of indirect or weak measurements, which is much easier to understand and more highly developed than the theory of direct (projective) measurements. A relativistic form of the ETH-Approach will be presented in a separate paper.
