Stocks & Candy. Western Union has already gone a long way toward shedding its 19th century image. It operates a nationwide system for the Air Force designed to detect nuclear bomb explosions, an automatic teleprinter network that serves 9,129 customers in 2,000 U.S. cities and a private telephone system for the Philadelphia-Baltimore-Washington Stock Exchange. Its 30,000-mile facsimile-data-voice net serves the National Aeronautics and Space Administration, and a bigger hookup works for the Pentagon. In September, it opened a "broadband exchange service" to 19 cities that not only combines telephone, teletype and facsimile communication...
...this world that I was depicting. The crux lies not in the quality of such gifts as I have, but in spiritual hastiness, in the fact that we were blinded by tremendous events, deafened by cannonades, by roaring, by intensely loud music, so that at times we ceased to detect the nuances, hear the heartbeats, and so lost the habit of discovering that spiritual detail which is the living tissue...
...industry spends $35 billion a year on quality control-almost all of it to detect and correct mistakes after they occur. If Z.D. can continue to motivate people to better craftsmanship, it could save much of that...
Underground tests, such as the one that the U.S. conducted last week in a salt dome near Baxterville, Miss., are much more expensive and not as convenient to observe. They are also harder to detect and might well be carried out in secret...
...were also alert. Any nuclear explosion sets off a great variety of electromagnetic waves, some of which are in the radio segment of the spectrum. They travel great distances, guided around the curve of the earth by ionized layers in the upper atmosphere, and they are not difficult to detect. The explosion-born pulse of radio waves disappears quickly, but another radio effect lingers on. As the mushroom cloud climbs into the stratosphere, its radioactivity releases a vast number of electrons that ionize a mass of air and turn it into a radio wave reflector. This air mass shows...
