Unsong is one of my favorite books ever, and the newly released print edition has some nice changes to the "base model" that I enjoyed a lot. The book honestly changed the way I thought about religion. It's fantastic.

(also, I liked Antimemetics, but not Ra, so I will just say I think unsong is leaps and bounds better than Ra)

I think Unsong is less math/physics and more just mega nerd. But it has a very very similar vibe. I love it so far (on chapter 20 or so right now).
