“Inventory” by Carey Young. The artist was weighed on June 27 2007, the date on which this art work was commissioned. In consultation with two scientists, Dr. John Emsley (University of Cambridge) and Dr. Ilya Eigenbrot (Imperial College London), calculations were made as to the mass and current market value of each chemical element present in the artist’s body at the time of weighing. The total market value of these elements (expressed as a graphic on the wall) plus a print of the calculation data constitute the form of this piece. The calculated market value also represents the initial sale price of this piece.
