The work is a Carrara marble sculpture engraved with traces derived from still frames taken from a one-second recording of a Wilson cloud chamber. The engraved shapes correspond to particle trajectories observed within that precisely delimited temporal interval. The traces are transferred onto marble through precise sandblasting and refined through manual engraving.
The title 9192631770 refers to the scientific definition of one second, defined as the duration of 9,192,631,770 cycles of radiation corresponding to the transition between two hyperfine energy levels of the ground state of a caesium-133 atom.
The sculpture functions as an individual record within the series 9192631770. It is produced through the same procedure as the other works in the series and operates as a single, partial inscription of a measured fragment of subatomic particle movement.
