From top quarks to the blues
Library of Congress-sponsored research will help Berkeley Lab physicists digitize audio data encoded in the hill-and-valley surface of Edison wax cylinders. This three-dimensional scan of a portion of a cylinder was acquired with a non-contact confocal optical probe, and provided by STIL SA of Aix-en-Provence, France.
