...described a bolometer to top them all. Its sensitive surface is columbium nitride cooled by liquid hydrogen to minus 432° F. At this temperature-close to absolute zero-columbium nitride becomes "superconductive"; its electrical resistance almost vanishes. When a heat ray hits it and warms it only one millionth of a degree, it gives a clear electrical signal...
...receiving end, the mingled snatches are sorted out by another special cathode-ray tube and distributed to 24 listening telephones. Each set of one-millionth-of-a-second pulses blends into a smooth, clear voice, for the pulses come so close together that the ear cannot note the silences between them...
...same reason that a man roaring incessantly at a cliff would get back only a confusing noise. To get a clear, time-able echo, he must utter a short, sharp shout. That is exactly what radar does. It sends staccato "pulses" of electric energy, each less than a millionth of a second in length, at a rate of about 1,000 a second. Each pulse has time to make a round trip (about a thousandth of a second for a target 100 miles away), and record its message without interference from the next...
...world's greatest geniuses, no question about it." The Stretch. When, in March 1941, the process was discovered for manufacturing the atomic explosive, chemists feared it would take years to perfect a method of making it in quantity. Measurements accurate to 3% of one microgram (about one two-millionth the weight of a human breath) had to be established...
...millionth French repatriate returned from Germany to Paris last week. Most of the million wore ragged clothes and battered shoes. At first they stood gossiping, joking, exchanging experiences and sharing cigarets in front of the Maison des Prisonniers (Prisoners' Reception Center) in Paris' Quartier de l'Europe. But soon small raiding forces, guided by individual "reconnaissance units" of ex-prisoners, peeled off to obtain by "peaceful infiltration" of food and clothing stores the necessities promised (but still unprovided) by the Government. Minister of Prisoners & Deportees Henri Frenay and Food Minister Paul Ramadier had good intentions but lacked...
