Known Unknowns


Final year Design Interactions students Steffen Fiedler and Jonas Loh, studying at London’s Royal College of Art, presented the first part of their collaborative project, Known Unknowns, at the interim ‘work in progress’ show.

With random numbers used on a daily basis for security encryptions, Known Unknowns questions our relationship with randomness by delivering two different methods to generate truly random numbers.

The Random Event Harvester is a portable device that detects radioactive particles to generate numbers based on geographical location, with data visualised as three-dimensional etchings and millings.

Meanwhile, The Cosmic Ray Detection Chamber is based on a cloud chamber (which is used for detecting particles of ionizing radiation) to visualise the track of sub-atomic cosmic rays originating from outer space to generate true random numbers.

The Design Interactions Work in Progress show ran from February 2-7 2011.
The Royal College of Art Show will take place from June 24 to July 3 2011.
