I read cozy and historical mysteries, a bit of Paranormal/UF, and to mix it up, I read science and gardening books on occasion.
Chapter 3 is, for me, the best description of surface tension I've yet to read. She explains it so well I can picture all the little H2O molecules pulling and tugging on each other in every direction - except for the molecules on top; they're only being tugged on sideways and downwards, and that's why a water drop looks like a drop.
Chapter 4 is all about the incessant march of everything - living or not - towards equilibrium. No stand out anecdotes in this chapter, but I can't help wondering if humans aren't an exception tooth's law of thermodynamics; we seem intent on knocking everything in our path out of equilibrium.
