A Brief Review of the "ETH-Approach to Quantum Mechanics"
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 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.
