An interesting book is out: Information, Physics and Computation by Andrea Montanari and Marc Mézard. See this blog post for more detail.
I like this book and have already got myself lost in it. The title is confusing; they should've called it "Phasetransitionology" like the awesome Generatingfunctionology.
Here's our place to discuss Less Wrong topics that have not appeared in recent posts. Have fun building smaller brains inside of your brains (or not, as you please).
