“Knowledge of Meanings” is a new, fundamentally revised edition of “Conversations with Dzhemal”, a book that contains all the television programs on the “Radio Mediametrics” channel with the same name. The releases of these programs were conducted by the channel’s journalist Oleg Druzhbinsky. The programs began recording in January and ended in October 2016. Almost every week, on one specific day, Heydar Dzhemal went on air to reveal, to one degree or another, for an hour, a topic that he himself determined for this program. In the first edition, the book contained many inaccuracies and errors, and several topics were missing. Therefore, it was decided to re-raise all the primary video material, rework it and compile it for its re-release. A lot of work was done to restore the video material that is available on the Radio Mediametrics channel, since some programs had technical glitches in the sound. Everything was deciphered as much as possible and transferred to “paper” from the very first program to the last. The publishing design was preserved in PDF A4 format.
