Here is a great work of high scientific content. This is not a popular book. It is aimed therefore at serious players with a background in higher mathematics. The spectacular images it offers a perfect illustration of its title "The beauty of fractals." For cons, the text of comments is awful moment. This is likely an Anglo-American translation made from the original text written in the native language of the authors. Moreover, we find here and there German words "forgotten" in the English text. Some phrases are all simply incomprehensible. Only for advanced players, philistines, abstain.
