ABSTRACT
As pointed out in chapter 2, in the conventional interpretation of the quantum theory (which is basically epistemological in nature) measurement plays a key role in the sense that without it the mathematical equations would have no physical meaning. In our ontological interpretation, however, we have started with a treatment of the individual, actual process, e.g. a particle penetrating a barrier, undergoing transition between stationary states etc. Evidently it is necessary to deal with the measurement process in essentially the same way; i.e. as a special case of quantum processes in general. What is particularly significant in a measurement process is that from a large scale result that is observable in a piece of measuring apparatus, one can infer the state of the observed system, or at least the state in which it has been left after the measurement process is over.
