Do you remember your school math lessons with a shudder? This is normal, because Ben Orlin, the author of this book, did not teach you. However, he did not 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 have the opportunity to understand the nature and structure of the things and phenomena around 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. Clever puns and amusing associations, mind games and digital riddles (each of which will give you an elegant and ironic solution) and, of course, the famous signature drawings (which, contrary to the title, are not so stupid) allow Orlin to convey the most complex and witty with ease and wit. deep mathematical ideas and convince us that even mathematics can be terribly interesting.
