In statistical terms, information theory entropy measures the probability of a system arriving at its present state, thus the higher the entropy, the higher the probability. Because the second law of thermodynamics is also statistical in nature and deals with probability, it is necessary to discuss the semantics of communication, and the element of uncertainty present in both theories. This sensory information allows for a more accurate description of the structure of a system, and helps to decrease the uncertainties, and the probability and entropy of the system that our message will enter into. Oedipa expends most of her mechanical energy running around California, trying to gather information about Tristero, the unstable structure. Thus for Oedipa, the more information that she gains about Trystero, the more confused and disorderly are her thoughts, pushing her to the point where reality and fantasy butt heads.
Repetition is helpful so long as it serves as a reinforcement, and establishes recognition.
Otherwise, signals would push a variety that borders randomness and noise. Conversely, monotonous redundancy in messages can also reach a point of banality and stagnation. The Crying of Lot 49 flirts with the entropy suicide that words have committed in V. . It is difficult not to draw parallels between the two theories, especially the way Nefastis does through Maxwell's demon. It was a coincidence.
