Virtual reality: Ralph Hollis, IBM, NY "Feeling" Gold Atoms working with a scanning tunneling microscope (STM) (at right) linked to a tele-robotic manipulation system with atomic scale force-feedback. The minute movements of the STM's probe as its traverses the gold sample surface is linked to a force-feedback magic wrist, enabling the scientist, whose hand is in contact with the magic wrist, to feel the texture of the gold atoms. In background is a false-color STM image of the gold surface, revealing the cobbled pattern of individual atoms. The photo was taken at IBM's Thomas Watson Research Centre, Yorktown Heights, New York. Model Released (1990)
