The Azimuth Blog is where the Azimuth Project publicizes its work. You can see it here.
This page is an index of articles on the Azimuth Blog. The sections are for series, or other topic categories, and are listed alphabetically. For other articles, there is a section called Authors, with one subsection per author.
The index is up-to-date through 8 Oct 2014. Also see Blog articles in progress.
If you want to write your own blog article, please do! But there are some stylistic and formatting issues to think about. So, please start by reading How to write a blog entry.

These are notes for a course taught by John Baez in the winter quarter of 2013:
By John Baez. The web version is a bit more nicely formatted, but the blog version has comments, and of course you can post your own comments there:
Part 1 - the Fisher information metric from statistical mechanics. (website version)
Part 2 - connecting the statistical mechanics approach to the usual definition of the Fisher information metric. (website version)
Part 3 - the Fisher information metric on any manifold equipped with a map to the mixed states of some system. (website version)
Part 4 - the Fisher information metric as the real part of a complex-valued quantity whose imaginary part measures quantum uncertainty. (website version)
Part 5 - an example: the harmonic oscillator in a heat bath. (website version)
Part 6 - relative entropy. (website version)
Part 7 - the Fisher information metric as the matrix of second derivatives of relative entropy. (website version)
Part 8 - information geometry and evolution: how natural selection resembles Bayesian inference, and how it’s related to relative entropy. (website version)
Part 9 - information geometry and evolution: the replicator equation and the decline of entropy as a successful species takes over. (website version)
Part 10 - information geometry and evoluton: how entropy changes under the replicator equation. (website version)
Part 11- information geometry and evolution: the decline of relative information. (website version)
Part 12 - information geometry and evolution: an introduction to evolutionary game theory. (website version)
Part 13 - information geometry and evolution: the decline of relative information as a population approaches an evolutionarily stable state. (website version)
