Do you shudder when you remember your school math lessons? That's normal, because you didn't have Ben Orlin, the author of this book, as your teacher. However, even he didn't immediately think of explaining to his students that, in fact, mathematics underlies everything in the world: from the lottery to Star Wars, from the recipe for chocolate pies to elections. And that those who have mastered the basics of exact science get the opportunity to understand the nature and structure of the things and phenomena that surround us. Orlin acts not only as a teacher, but also as an illustrator: his funny little men and squiggles have captivated thousands of schoolchildren, and they will captivate you too. Elegant puns and funny associations, mind games and numerical riddles (for each of which you will receive an elegant and ironic solution) and, of course, the famous signature drawings (which, despite the title, are not so stupid) allow Orlin to easily and wittily convey the most complex and profound mathematical ideas and convince us that even mathematics can be terribly interesting.
