...factories, and the other fruits of modern technology often cause as many problems as they solve, Fighting Progress has been an honorable American pasttime. One of the most active current crusaders on this front is William A. Shurcliffe, whose role at Harvard is senior research assistant at the Cambridge Electron Accelerator, but whom Congressmen and airplane builders know better as the muckraking director of the Citizens League Against the Sonic Boom...
What do these diseases of man and beast have in common? Probably, says Dr. D. Carleton Gajdusek, a top researcher at the National Institute of Neurological Diseases and Blindness, they are all caused by extraordinarily slow-acting viruses-none of which has yet been definitely seen, even with the electron microscope...
...Hahn were on the verge of achieving nuclear fission. When Hahn sent her the details of his experiments with uranium some months later, she completed the immensely complex mathematical calculations proving that he had indeed split the atom and, in the process, released a fantastic 200 million electron volts of energy...
Different Shapes. The target of all medications that suppress organ rejections is what the experts call "the transplant antigens," protein molecules that are too small to be seen even with the electron microscope. Apparently they sit on the outside of the body's cells, ready to trigger an antibody reaction and rejection phenomenon if the cells are transplanted, as part of a kidney or heart, into another person...
Schumacher aims his electrons through a series of chambers from which pumps are continuously evacuating the air. By simply blowing a steady stream of inert gas past the final hole-the muzzle of the gun - he stops dirt and debris from being sucked back into the vacuum. No wider than a sixteenth of an inch, the electron beam, says Schumacher, can cut iron bars, granite blocks or slabs of concrete. Only requirement is that the gun be kept virtually on top of its target. From a half inch out, it can burrow up to four inches into the toughest stone...
