In vain do we think that we live in a world that everyone has known everything about for a long time. In fact, we are surrounded by unknown, unexplored, misunderstood. You just need to want to see these miracles, rejecting laziness, disbelief, rejection of the alien and unusual. The encyclopedia, compiled by V.A. Chernobrov and his colleagues in the search for the unusual, reminds us that we are not alone in the Universe, that sometimes miracles are next to us just as people live and work next to us, who, once touching the unusual, devote their whole lives to studying it.
