What Is Entropy?

Entropy is a complex concept explored in a book draft by an author on Azimuth. The book delves into the idea of entropy as the amount of unknown information in a situation that could potentially be learned. It covers various topics such as information theory, Shannon entropy, Gibbs entropy, and the Boltzmann distribution. The author avoids delving into the second law of thermodynamics and the role of entropy in biology and black hole physics. While the book contains mathematical content, it aims to keep physics prerequisites low. Planck's constant plays a role in defining the entropy of classical systems like hydrogen gas. The book emphasizes making concepts precise and exploring subtle physics issues. Readers are encouraged to focus on the key points highlighted in boxes throughout the text. The author's approach provides a detailed and structured entry point into understanding the fundamental concept of entropy in physics.

At first glance it's authoritative, comprehensive and very readable. But then what else would you expect from John Baez?

I look foreward to reading in detail. And I don't expect to find errors (if only I were that bright). :-)
