I feel I've been neglecting the Azimuth Project a bit for the last week, so here's my apology and my plans for the future.
I've been talking about entropy, information theory and a bit of biology and economics with a group of people here — I call it the 'Entropy Club'. In the process I got distracted by 'Rényi entropy', an obscure idea from thermodynamics which, I'm happy to report, turned out to be an incredibly well-known idea in disguise: namely, free energy. I put a short paper about Rényi entropy on the arXiv and blogged about it, and the comments I got quickly led to dramatic improvements in the paper. It's a great example of how working online speeds up progress.
But now I want to do these things, roughly in this order:
finish writing week309, about a Hopf bifurcation in a predator-prey model.
write a blog post about 'Petri net field theory' - some work I'm doing with Jacob Biamonte, which applies quantum field theory and category theory to Petri nets. This overlaps a lot with week309, but I'll separate them out somehow.
write the final blog post on Stabilization wedges.
On Friday I'm going to Angkor Wat for a week (it's right nearby), so I'll be quiet from the 18th to the 25th of February. I'll see how many of the above items I can do be Friday!
