If the reader enjoyed this chapter, then he might want to ask what lies further ahead and how he might prepare himself for a life of randomness. If so, I would advise him first to rebuild the foundations of his knowledge of probabilities by studying a book such as NEVEU [1]; then study the general theory of stochastic processes through a book such as DELLACHERIE [1]; then read the theory of Markov processes in a general setting, say through BLUMENTHAL and GETOOR [1]. And this is a most straightforward Christian piece of advice.
