My 9.25" x 12.5" linocut portrait of physicist Harriet Brooks (1876 - 1933) in a gradient of turquoise to green, shows her and her discovery of atomic recoil in gold (Radon gives off an alpha particle and daughter nucleus goes in opposite direction). A series of diagrams at the bottom shows how the Rutherford research group understood chains of radioactive active transmutations at the time.
