Vse o shifrakh i kodakh: v mire matematiki i kriptografii - Dushkin Roman Viktorovich

Summer holidays are usually a time under the sign of idleness and recreation, where there is rarely a place for new knowledge and hobbies. But even summer in the village can be turned into an amazing adventure, when there is always a mystery around you - whether it's a mysterious message on the wall and ciphers from the past or a case closed to a code lock, hiding its secrets. You and the main character Cyril will find a fascinating quest on the world of mathematics and cryptography, where knowledge of arithmetic, the basics of encryption, geometry and even geography will help to find a solution, at first glance, extremely complex tasks and puzzles. You will find a mysterious suitcase with a lock without a key, where you first need to pick up a cipher, then - to unravel a secret message, find and collect the keys to the whole encoded matrix, and then even make your own encryption machine and find a real treasure! You will see an old record from the 19th century, which will turn out to be a real map, pointing to hidden treasures! The main thing is to apply your knowledge of physics, logic and mathematics to correctly solve all the riddles and not to deviate from the right path. Knowledge of mathematics, logic and cryptography is not only a boring theory, but above all a practice that applies to all areas of our lives!
