This book contains unique facts on physics and geography, chemistry and biology, history and economics, religion and mythology, literature and art. Its main task is not so much to inform the reader as to arouse interest in a particular area of ​ ​ knowledge. Questions and answers will give him the opportunity to think about the amazing diversity of the world around him and about the amazing ability of a person to know him, about the limitless power of reason and his humiliating dependence on ridiculous prejudices, about the nobility and baseness of the human soul and much, much more.
