Linocut print of Chien-shiung Wu in indigo wearing a lab coat and holding a schematic diagram of her famous violation of parity experiment (in blue and indigo) on the left side. The right side shows the mirror image except in the schematic diagram. The left side schematic shows a C shaped electromagnet open to the left. The top is labeled S, the bottom is labeled N and the middle is wrapped in wire drawn as a circuit diagram schematic with parallel lines to indicate a power source and left arrow on top wire, right arrow on bottom. Between the poles of the magnet is a big blue dot to designate Cobalt-60 with many tiny dots as beta-decay electrons, the majority going downwards to N pole. On the right, everything is flipping except most electrons go upwards (and and N and S poles are flipped).
