PHOTONIC WIND | 2013 | installation Shining into a vacuum chamber, a laser beam levitates and propels diamond micropowder. Forming starry jets and languorous vortical clouds, the diamond dust evokes light’s pervasive flow, insuppressibly transforming everything in its wake. Photophoresis (light-induced migration of matter) has recently been proposed as the phenomenon responsible for planet formation: light-propelled rotation of cosmic dust gradually snowballs into a planetesimal, the seed of a planet. Simultaneously revealing the slow motion birth of a planet and the rapid dynamics of photo-molecular interactions, Photonic Wind decisively extends the viewer’s sense of spatial and temporal scale. img video  © 1998 - 2023 Domnitch Gelfand |
