The Monsters and Magic of Entropy

I just came to and realized that I have toppled head first down the rabbit hole of information theory. I have only a vague sense of how I got here. I remember reading Umberto Eco, typing out a quote, looking up a term. I might have clicked on a hyperlink. But now I’m face to face with the monsters and magic of entropy, black holes, transinformation, and Kullback-Leibler divergence and have no idea how to extricate myself without triggering a quantum data loss or a disequilibrium resulting in certain theoretically-posited molecular annihilation.
