Since the encyclopedia contains addresses of research organizations and advice for beginners, in fact this book is an invitation to readers to deal with the identified scientific problems through joint efforts. What is the difference between telepathy and empathy and teleportation from chronoportation? Where does poltergeist come from? What is the most dangerous place in Russia for humans? Why, in our enlightened age, cannot scientists figure out what was considered obvious to a medieval citizen? This encyclopedia is about all this and much more, which contains articles about mysterious, unusual, strange places and facts directly or indirectly related to the problem of studying SL.
