Good Thursday Morning to you all. Today's picture shows Robert Oppenheimer and Leslie Groves. Oppenheimer was one of the main physicists on the Manhattan Project, and Leslie Groves was the military man in charge. In the picture above, they have returned to ground zero after the successful test of the gadget.
The location of the test was the Trinity Sight in southern New Mexico. After the blast, the sand in the area was turned to glass. The glass ground had a greenish hue, and the little pieces of green glass were given a new name . . . Trinitite. The glass is still slightly radioactive to this day. While the material can no longer be picked up at the Trinity sight, it is collected and traded by rock hounds and mineral collectors.
