It’s not often that you find a math book that opens with a joke. I mean, literally in the opening, just before the preface:
Question: How many months have 28 days?
Mathematician’s answer: All of them.
(Okay, it’s no ‘man from Nantucket’ but I got a chuckle out of it.) I also found one of my favorite footnotes:
….use or like mathematics are considered geeks or nerds*
* Add your own favorite term of abuse for the intelligent but unstylish.
This was just in the preface (ProTip: always read the preface, kids!).
The author, Kevin Houston, teaches at the School of Mathematics at the University of Leeds. His dry British wit is evident throughout this very readable text. But this isn’t just a math-oriented joke book. It’s a solid collection of mathematical ideas and skills starting with sets and functions through proof techniques and equivalence relations. Houston wraps up with a discussion of how to recognize true mathematical understanding.
