I won't claim the author is mathematically illiterate. I don't know. But this is where math shines. Show the equation and how it it models the phenomenon. Match it against measurements. If it doesn't match, make another model. Without that, talking about entropy as if it isn't a useful way of conceptualizing phenomena is just word soup.
