How Not to Be Wrong: The Hidden Maths of Everyday Life - by Jordan Ellenberg

Although this is essentially a technical book, it kept me engaged and it was not a hard read. There are lots of memorable stories [that are easy to re-tell], including “the missing bullet holes”, “the Baltimore stockbroker”, 2 states claiming 125% of the employment increase one month and a technique to send self-correcting data messages by repeating bits/characters [which is very analogous to safety critical system design]. The author is clearly enthusiastic about his topic and that is somewhat contagious.

Although I am totally OK with reading US English, I did find the extensive use of American football and baseball as examples tedious, as these games are a complete mystery to me. There is the odd bit of sloppy writing. For example, a reference to “3 alternatives” - surprising for a mathematician.
