Der Sprung, 2017 (detail of the diptych)
Der Sprung (How the Earth shakes when I jump)Performance, Berlin 2014Inkjet print / drawing diptych, Berlin 2014Publication 'Der Sprung (How the Earth shakes when I jump', Berlin 2014IBB Preis für Photographie 2014In an elaborate calculation Felix Kiessling illustrates how the planet's celestial mechanics cushion his impact – the moment he jumps up and falls back onto ground again. The effect is incredible small, still mathematically feasible: 'When I jump, the Earth slows down by 1.674032409267443 x 10-22 meters per second. (At this velocity, both masses cover a distance of 1 meter in 189421613394216 years.) When I jump, the Earth‘s elliptical orbit decreases in its semi-major-axis by 0.3 mm and in its semi-minor-axis by 0.2 mm' 'Wenn ich springe, verlangsamt sich die Bewegung der Erde um 1,674032409267443 x 10-22 Meter pro Sekunde. Wenn ich springe, verkleinert sich die elliptische Erdumlaufbahn in ihrerHalbhauptachse um 0,3 mm und in ihrer Halbnebenachse um 0,2 mm.'
