Tom Apostol is well known as the author of books on calculus, analysis, and analytic number theory. He is also becoming known for his interest in creating mathematics videos, in particular through his Project MATHEMATICS! series. Here he shows us another side of his talents. In the introduction, he tells us that he has been constructing acrostic puzzles, off and on, for more than twenty years. This large size booklet gives us ten of his puzzles, in which all the clues have to do with mathematics. The subtitle says the book is "for those who are amused by words." In my experience, that includes many (maybe even most) mathematicians. So, if you'd like to spend some time having fun with mathematical words, grab a copy of this one.
