The starting point for the installation is the so-called Bogen-Lipmann cage, an object to measure spatial-visual intelligence, which is used in career counseling even today. One of the names of the device comes from Otto Lipmann, a significant German psychologist of Jewish origin, who was laid off in 1933, and after his journal was banned by the National Socialists and the Department of Applied Psychology was destroyed, he committed suicide. The installation made for the exhibition “[silence] – A Holocaust Exhibition” in 2014 on the one hand commemorates the outstanding scientist, and on the other hand, it presents a construction that, in addition to a historical approach, examines the nature of spatial-visual thinking. In ÁDÁM ALBERT’s conceptual art, scientific thinking, scientific and philosophical theories, as well as the models and diagrams that illustrate them play an important role.
