Meanwhile, there were outcries from the political fringe. Both the Dixiecrats and the Progressives, certain that they would poll sizable votes, were aroused; they were far from amiable, and the issues they raised might be serious enough to cause some permanent political realignments. But between now and election day, those minor voices would recede into a distant, thin scream which would be pretty well drowned out. The major candidates would occupy the center of the stage...
...electrical energy passes along their interconnecting fibers. When it reaches the "synapses" where the fibers touch those of other nerve cells, it may pass the impulse along. Or it may not. This "yes-or-no" response of the neurons, Dr. Hoagland believes, is the basis of brain operation. Certain calculating machines work the same way, their vacuum tubes or relays responding or not to the electrical impulses that reach 'them...
Waves of Memory. But how does the brain call up these "memories" when it wants them? Neurologists have known for many years, said Dr. Hoagland, that under certain conditions (when a person is awake with his eyes closed) waves of electricity, about ten a second, pass rhythmically over the top of his brain. These "alpha waves" have been used to diagnose various brain conditions, but for a long time no one understood their function. Now, said Dr. Hoagland, many neurologists believe that they are "scanning devices" like the electron beam that scans the image in a television transmission tube...
...suicide, but next day Columnist Pearson hinted that it might have been murder. The circumstances, he said darkly, "are strange indeed, including the fact that Porter jumped-or was pushed-through a window screen. This is not an ordinary act of suicide." Pearson said Porter had told him that certain people had been trying to force him to return to Scotland (he was a British subject), because "apparently some people believed he knew too much." Porter had told some friends of attempts to blackmail him, and he was sure he was being shadowed. Other friends of Porter said...
Titanium was once regarded as a chemical curiosity. When it turned up as an impurity in certain iron ores, it was reclassified as a chemical nuisance. Then chemists learned how to remove titanium from iron ore, and found that its oxide is intensely white. So titanium dioxide got a job as a pigment for white paints. But until recently no one had much hope for the pure element as a metal. Getting it out of its ores in metallic form was very difficult...
