...continuing problem. Because of friction in the bearings of their spinning wheels, they tend to drift slowly away from the proper direction, and so give false readings. This annoying weakness may soon be corrected. Scientists at Republic Aviation Corp. are hard at work for the U.S. Navy developing a gyro with no wheels, no bearings, and no friction at all. Its only moving parts will be subatomic protons...
...changes direction, it tries to pull the protons around with it. But protons have a mysterious property called "spin" that makes them react like small spinning wheels. When the magnetic field changes direction, they do not follow obediently. Instead, they resist the turning motion, just as if they were gyro wheels...
...monitor shows red. Circuitry reads out of continuity. Gyro out of specs on countdown group...
...accuracy was no longer good enough. A master standard must be at least ten times more accurate than the practical measuring systems that are derived from it, and modern industry began to call for tolerances expressed in millionths of an inch. An error of this infinitesimal order in a gyro guidance system might send a space probe to the wrong planet, millions of miles off the track...
...withstand the pounding seas and polar ice of the wildest stretch of the North Atlantic Ocean, off the barren shores of Greenland. She had a double steel bottom, an armored bow and stern, and was divided into seven watertight compartments; she carried the most modern instrumentation, from radar to gyro, from Decca Navigator to radio-equipped life rafts. Her veteran captain, P. L. Rasmussen, 58, declared: "This ship means a revolution in Arctic navigation." Boasted a government official: "Now we can sail to Greenland all year round...
