...Projective Tests," given at the final section meeting, asked each student to interpret a picture. Interpretations will be studied for reactions to the method of instruction...
...scientist; his selection of material was excellent; he knew what was important and what was not. By November the FBI had another lead: the Harwell informant probably had worked in the U.S. because he knew the "mechanics" as well as the physics of the bomb. (The method of detonating the bomb has always been the gravest U.S. secret.) The field was thus sharply narrowed and the closest surveillance set up over a handful of scientists. Of those, the one most closely watched was Fuchs because, in cross-checking, investigators recalled that his name had turned up in a notebook belonging...
...ingredient tritium (hydrogen 3) is radioactive and is excessively rare in nature, but it is not hard to make. One method is to bombard lithium 6 with neutrons in a uranium pile. The reaction yields tritium and helium, which can be separated by simple chemistry. This job could be done in the plutonium-making piles at Hanford, but probably will be done in a special pile built without difficulty for the purpose...
...Aeply method could not be patented; it was mostly a matter of loving care in the use of old crafts. Most art-reproduction firms, Janine explained, "concentrate on color alone. But a painting has texture as well. To simulate that we use dozens of materials: cardboard, paper, stencils, canvas, silk screens . . . Sometimes we use as many as seven different processes to reproduce one original." Janine and Jean had built each blob of pigment up to the same thickness as that in the original paintings. They made as many as 600 facsimiles of each painting, sold them...
...Mexico experiments were done by Project Cirrus (sponsored by the Army Signal Corps and the Office of Naval Research in consultation with General Electric Research Laboratory), and the experimenters tried a more subtle method...
