Probability, Entropy, and the Foundations of Physics

Instead of the more traditional view of physics as a direct description of reality, our goal is to formulate physics as a set of models or tools to make probabilistic inferences about reality. The development of such an “Entropic Physics” requires the development of Bayesian and entropic methods in order to clarify the interpretation of the concepts of probability, information, entropy, and information geometry. This material together with its application to the foundations of statistical mechanics and of quantum mechanics is presented in the (still unfinished) book "Entropic Physics.”
