...side are those who are drafted, or who enlist under pressure. Few of them ever go to Vietnam, and only a fraction of the soldiers in Vietnam ever see combat. But the experience of serving in the military during wartime, like the experience of war itself, changes all of them--cramming a large piece of hell into a few short years, ignoring the shelters provided in civilian life by education and wealth...
...that Adam Clayton Powell is "a Negro who has managed to outplay Whitey at his own game" [Dec. 9] is to encourage the useless emotions of race rivalry. Blaming Adam on the small fraction of Negro heritage he claims and abuses is as inappropriate as blaming the "game" you speak of on Caucasians, for Powell cannot sensibly be considered Negro any more than he can sensibly be considered truly American. The sensitive person of Nordic, African or whatever stock you please places men like Powell in the simple category, "moral garbage," which is a totally integrated system...
...slickly packaged Broadway sentimentality, shrewdly calculated to flatter middleaged, middle-class couples into thinking that their cup is brimming with sunshine and moonglow. The show becomes palatable for two surpassingly good reasons-Mary Martin and Robert Preston. They are charmers of seismic force and theatrical perfectionists to the fraction of a nuance. They complement each other's temperaments. Preston hisses energy. He is as restless and agile as a panther. There is no repose in him, and the world is a woman to be won. Mary Martin exists to be wooed. She focuses light, as a magnifying glass brings...
...been encouraging the use of safer X-ray machines for years, many devices of antique design still adorn countless offices. Some have not even been equipped with an electronic timer, available since 1955, to go with the use of high-speed film and cut the exposure time to a fraction of a second. The vast majority still have, at their business end, a plastic cone three or four inches long. This makes aiming easier, but, unless specially insulated, it permits secondary radiation to scatter in all directions...
What the U.S. Public Health Service recommends, and the A.D.A. approves, is a machine that delivers an X-ray beam 2¾ in. in diameter. Extra-heavy aluminum filters weed out useless rays, and lead shielding keeps all radiation within bounds. The patient gets only a small fraction of the radiation that was sprayed out of pre-1958 machines...
