"Tilting of the real time axis. Remarks on the reversibility of the uncertain" is set apart from the artistic work that can be expected: Boden, with his scientific training, creates parallel worlds in which he takes urban planning, social and historical situations as the starting point for his research and questions. Unbelievable but forgotten inventions are brought to light from various archives. Like a person of a different faith who rings our doorbell unprepared, Boden convinces us of his results and leaves us alone with last doubts, which he juggles back and forth before our eyes with irony and humour. Based on real circumstances, such as known places or situations, Roland Boden assembles detailed inventions and imaginary familiarities, but also meticulously researched material to feed his "research" with the necessary content. In various real archives he finds evidence to back up his incredible discoveries, which are compiled in this book project. The artistic work is so precisely translated into the book form here that one cannot imagine any other implementation. It is the ideal form for Roland Boden's nostalgic stories, because such assertions have their home in books. The publication is rich in detail and designed with the same scientific implicitness: Linen binding, foil embossing, chapter volume and classic working paper give the book bibliophilic value.
