After a short introduction to some of the conundrums afflicting Quantum Mechanics, we study the effective quantum dynamics of systems interacting with a long chain of independent probes, which, afterwards, are subject to direct (projective) measurements and are then lost. This leads us to develop a theory of indirect measurements of time-independent quantities, so-called non-demolition measurements. Subsequently, the theory of indirect weak measurements of time-dependent quantities is outlined, with emphasis on the description of Markov processes whose state spaces are spectra of quantities to be measured.
