Abstract: The Ergodic Theorem serves as a link between dynamical systems and random processes. In this lecture, we will illustrate the theorem by developing a case study of continued fractions. As a corollary, we will obtain the celebrated theorem of Khinchin: for "almost every" positive irrational number x, the geometric means of the continued fraction expansion of x converge to the limit K=2.6854520010653064453...
