»Traces«, 2007. The Traces series is a number of 14 photographs that document the numerous traces of cosmic and terrestrial radiation, which ionize the gaseous ethanol steam inside a cloud chamber.
»334 m/s«,2007, is a room installation, which is meant to visualize the speed of sound (c = λ ⋅ ƒ), which is about 334 m/s. Two translucent tubes are filled with propane gas, which is set on fire to cause a chain reaction. A flame is burning from one side to the other, slowly accelerating to the point where it hits the end of the tube. Due to the ratio of the gas-oxygene mix the flame there causes a rapid explosion, which can be heard as a sonic boom. By Carsten Nikolai.
