A kind of weapons educational program for readers and writers of all science fiction (and not only!) schools, styles, trends. Heroes of modern science fiction are much more likely to grab a sword than a blaster; and they are dressed in armor much more regularly than in spacesuits. Another question is what is the degree of reliability... So, if you read this book, you will find out in which pocket a catapult is carried, what button the armor should be fastened with, and how to properly shoot an anti-aircraft crossbow at a dragon! This is a collection of articles published in the magazine "The reality of fiction."
