The purpose of Event Enhanced Quantum Theory (EEQT) is to allow for a precise meaning to the concepts of “event”, “experiment” and “measurement” Within EEQT one obtains not only Lionville equations describing the continuous dynamics of statistical ensembles but also a unique minimal piecewise deterministic random Markov process (PDP) than can be used for computer simulations of real time series for experiments on individual quantum systems. EEQT is therefore particularly relevant to today's experimental Quantum Physics since new technology needs new laws and its range of applications is rather wide. As an example a cloud chamber model will be discussed. In a particular, homogeneous, case this model contains GRW spontaneous localization model. All probabilistic interpretation of Standard Quantum Theory can be derived from the formalism of EEQT. Moreover EEQT has no need for observers or minds. EEQT is a precise and predictive theory not only giving enhanced answers but also inviting asking new questions for example on the grand vision of a Quantum Theory of history à la Gell Mann-Hartle or on Connes' version of the Standard Model. In conclusion EEQT is a minimal extension of the Standard Quantum Theory that accounts for events and satisfies the needs of human experience and modern technology.
