The most recent installation by the internationally acclaimed artist Alicja Kwade (b. 1979), who comes from Katowice, explores the French physicist Léon Foucault’s (1819–1868) proof that the world rotates and develops the experiment further. The present volume illustrates the playful exploration of space and time using recent pictures from the Schirn rotunda. The Berlin-based artist Alicja Kwade’s scientificlooking experimental setups are reminiscent of surreal and phantasmagorical constellations and objects. The fascination of her work, which cannot be explained by reason alone, is rooted in the skilful superimposition and sometimes paradoxical nature of scientific and social realities. Things that are generally taken to be established facts are called into question and disproved. Here the artist explores the true movement of time, which will have an immediate effect on both space and the viewer.
