I don't have a clue about the math, but I liked the puns in the preface to Knuth's "Concrete Mathematics": "When [Knuth] taught Concrete Mathematics at Stanford for the first time, he explained the somewhat strange title by saying that it was his attempt to teach a math course that was hard instead of soft. He announced that, contrary to the expectations of some of his colleagues, he was not going to teach the Theory of Aggregates, nor Stone's Embedding Theorem, nor even the Stone-Čech compactification. (Several students from the civil engineering department got up and quietly left the room.)" https://en.wikipedia.org/wiki/Stone%E2%80%93%C4%8Cech_compactification https://en.wikipedia.org/wiki/Stone%E2%80%93%C4%8Cech_compac...
