...with three nuclear warheads that could reach London in twelve minutes. The U.S. had withdrawn its last INF missile from Europe more than a decade earlier. In 1979 we and our NATO allies agreed that our objective in response to the SS-20s was to get the Soviets to pull them out. Failing that, we should counter these missiles with NATO deployments...
...many atoms, particularly those of metallic conductors, the outer shell has a number of empty slots, and the electrons that it does contain are not bound as tightly to it as those in the inner shells. Just as the sun's gravitational pull is weaker on distant Pluto than on nearby Mercury, the hold of an atomic nucleus is also weaker on electrons in the outermost layers...
...currents in the guideway coils, which then themselves become electromagnets. As power is increased, the opposing sets of magnets repel each other and lift the train into the air. Two other rows of electromagnets, one on each wall of the U- shaped guideway, repeatedly reverse polarity to push or pull on the coach's magnets and thus move the train forward...
...superconducting magnets in 1979. They opted to use conventional electromagnets instead. The German system is based on magnetic attraction, not repulsion. The magnets are on assemblies attached to the cars' undercarriages that curve around and under the crossbar of a T-shaped track. When the magnets are energized, they pull themselves up toward the crossbar's metallic underside and the car is lifted into the air; magnets in the track provide propulsion. Which technique is better? Both have advantages. The German maglev is simpler and less expensive to operate. But so far the Japanese trains are about 100 m.p.h. faster...
...convicts killed all four family members who had been in it, including a two-year-old. After fleeing a shoot-out with police, the father died of exposure in the desert. The sons were eventually convicted of murder and sentenced to die, even though they did not pull the trigger...
