摘要

The chapter examines through a number of simple examples the thread along which an observer is pushed to build a theoretical probabilistic model to describe the physical world. It is found that complexity is always a root of the indeterminacy of the results of experiments; this can manifest itself by the instability of the theoretical model and the impossibility to control the conditions under which the experiment is conducted.
