  The counterexamples to RCT offered in  §§4.3–4.4  suggest strongly that the appeal of RCT depends on our curious tendency to take independent identically distributed trials, like the Bernoulli process of fair coin tossing, to be paradigms of chance processes. Yet when we widen our gaze to encompass a fuller range of chance processes, the appeal of the right-to-left direction of RCT is quite diminished. It is now time to examine potential counterexamples to the other direction of RCT. There are a number of plausible cases where a random sequence potentially exists without chance. Many of these cases involve interesting features of classical physics, which is apparently not chancy, and yet which gives rise to a range of apparently random phenomena. Unfortunately some engagement with the details of the physics is unavoidable in the following.
