Benjamin Roberts examining Model of Momentum

Model of Momentum, machined from aluminum with 14 concave faces being examined by Dr. Roberts at the General Electric Research Laboratory in Schnectady, New York.  In the background is a diagram illustrating how measurements of the momenta of conduction electrons are made (represented by the calipers), as sound waves (q) are sent into a metal sample, in which their direction of movements is controlled by a magnetic field (H)., Credit Line: AIP Emilio Segrè Visual Archives, Physics Today Collection
