Description:
One of the most successful physicists of the generation immediately before Hugh Everett III, E. T. Jaynes shared both Everett's interest in applications of information theory to physics and his foundational orientation. But whereas Everett focused on quantum mechanics, much of Jaynes' work concerned how to use information theory in thermodynamics. This letter is a response to comments Everett made on Jaynes' paper "Information Theory and Statistical Mechanics," Physical Review, 106, 620-630 (1957). Jaynes claims his theory of information in statistical mechanics Is similar to Everett's theory (Everett seems to have included a preprint of his forthcoming Reviews of Modern Physics article with his letter to Jaynes). Everett is not convinced, as is clear from his marginal comments on the letter.
