Explain the profound connections between thermodynamic entropy (Boltzmann, Clausius) and information entropy (Shannon). Discuss (1) the mathematical foundations of each form of entropy, (2) Maxwell's Demon paradox and its resolution, (3) Jaynes' principle of maximum entropy as a bridge between the concepts, (4) Landauer's principle and the thermodynamic cost of information processing, and (5) the implications of these connections for understanding the relationship between information and physical reality. Conclude with reflections on how this unification influences our understanding of both disciplines.
