Because reading this textbook should be fun - but as a side effect the reader should also learn the basics of mechanics without suffering to much! Or to say it more officially: The scope of the textbook is to teach mechanics by means of simple examples from everyday life instead of sophisticated scientific approaches. The examples, supported by a lot of cartoons, should help to learn by associations and practical experiences. A similar textbook has not existed before - the terms 'mechanics' and 'fun' have always been contradictious.
