In the middle of Buckminster Fuller’s Radôme, Céleste Boursier-Mougenot presents clinamen v4: “In a pool half filled with water, some forty bowls float and move about. An immersed water pump produces a slight diametrical flow, causing the objects to drift and collide gently and to produce sounds as they do so. The temperature of the water is maintained at about 30 degrees Celsius by a system of heating elements, in order to ensure optimum resonance of the objects. Each of these objects has been chosen for its unique sound, for the note it produces when it chimes.” (Céleste Boursier-Mougenot). In Epicurean physics, ‘clinamen’ is the unpredictable swerve (literally, a ‘decline’) of atoms in their fall into the void; the swerve that causes atoms to collide.
