“What if a counter proof makes any proof an illusion? deals with photography as a means of proof and how it is and has been used to prove and support hypotheses and theories. Furthermore, the book explores the question of the extent to which aesthetic impulses influence the formation of theories, why a theory is ascribed a greater (scientific) truth content due to its elegance. Understanding beauty as a property of the (scientifically) true has a long tradition and this is not only to be critically questioned, but also to be made visually useful for the book. The book is symmetrically structured: Photographs from various urban contexts, each taken from slightly shifted perspectives, are followed by repro photographs of pairs of snow crystals. The book refuses to provide the viewer with explicit answers, but does give hints through text fragments (on supersymmetry, among other things) as to how the book might be read. The aim is to lure the viewer visually onto a trail, to tempt him to look at the photographs attentively in order to search for possible evidence himself. In this sense, the book illuminates different levels of observation and the relationship to the observer, which is referred to in the insert, both with the photograph from CERN and with Miek Zwamborn’s text ‘Amalgam’.”
