Linvill's "Opticon" (for Optical Tactical Converter) reflects an enlarged image of each letter onto a disk of light-sensitive transistors. The transistors, energized by the image, trigger a corresponding group of pins that vibrate in an outline identical to the printed letter. By lightly fingering the pins, the blind person can "see" the letter...
...days after the Indianapolis disaster, the very same flight-Allegheny 853-came perilously close to another mid-air collision with a light plane while departing Greater Cincinnati Airport. Fortunately, in this instance the unidentified light plane suddenly showed up on airport radar when the two craft were within five to ten seconds of crashing-just enough time to warn the jetliner away...

By the 1950s, when as many as 125,000 people were visiting the site annually, the French had installed an elaborate air-conditioning system in an attempt to restore the original conditions of humidity, temperature and carbon-dioxide concentration in the cave. Nonetheless, the precautions failed...
Like other algae, Palmellococcus thrives on light, moisture, mineral salts and carbon dioxide. Yet when it can feed on such organic substances as sweat, pollen and bacteria-which were also brought into the grotto-it will multiply well even in dim light. If enough of these nutrients are present, it can survive without any light at all. In fact, it was this steady buildup of organic matter, Lefevre and Laporte say, that enabled Palmellococcus to proliferate even when the cave was shut down and left in total darkness...
