...linear accelerator, a large cobalt-60 source, or a generator that puts out 2,000,000 electron volts. To protect the patient from radiation sickness and to spare normal tissue, healthy parts of his body must be shielded. At Memorial Hospital, said Dr. Nobler, an X ray with a grid background is made of the body area involved. On this X ray the radiologists mark the vital organs, such as lungs, which must be shielded. A template is made, and then engineers cut out lead shields 21 inches thick to this pattern. The shields, placed in the head...
...mechanism was triggered by a series of hidden photoelectric cells paired with infra-red light projectors, which together created an invisible light grid. The cells were located directly beneath the light bulbs; when the viewer's body intercepted an infra-red light beam, the cell triggered a relay switch to the bulbs above. Haacke's Photoelectric Viewer Programmed Coordinate System furnished little to look at, but lots to ponder at the coffee shops. Does a tree make a noise when it falls in the forest if nobody is there to hear it? Does a work of art cease...
Core Samples. SAC Major General Richard Hunziker's team-now grown to some 400 men-is using surveyors' transits to mark off a grid pattern around the crash site. As each piece of wreckage is found, it is plotted on the grid to establish the debris pattern that resulted from the crash, and detonation of the conventional explosives in each bomb. The collected debris will be shipped to the U.S. .in sealed containers for burial. The freight will be substantial. "Every piece of debris we've found so far is contaminated," reports Hunziker...

Another approach is the British "grid," calling for the creation of several self-contained neighborhoods-complete with schools, theaters, shopping centers and parks. Along these lines, Mayor John Lindsay's task force on urban design suggests that New York City, rather than pack even more skyscrapers into midtown Manhattan and Wall Street, should create a major business district along Harlem's 125th Street. Governor Nelson Rockefeller, in fact, has encouraged the move by ordering the construction of a 23-story state office building for Harlem. But New York, typically at odds with itself, is also building...
