...Womb at the Top." To abandon a foundering spacecraft, the astronaut dons extravehicular activity (EVA) gear, seals himself in the lifeboat and vents carbon dioxide and excess oxygen from his EVA suit to power the craft's attitude-control system. Face pressed against the porthole, he aligns his lifeboat with the horizon by firing the attitude-control jets. After sighting a landmark on earth with the reticle marked on the porthole, he aims and fires the retrorocket for 100 seconds, thus braking the lifeboat to a de-orbiting speed of 16,500 m.p.h. Then the retrorocket is jettisoned...
...hastened by cigarette smoking. Quite apart from the cancer question, said Gardner, smoking is the most important cause of broncho-pulmonary disease, is linked to stomach ulcers and heart disease (in which the death rate is 70% higher for smokers). Many researchers argue that the carbon monoxide, aldehydes and phenols contained in cigarette smoke are also pernicious-and are not stopped by filters. Moreover, some tars and nicotine still get through the Strickman filter. According to Dr. Stewart, "full protection can only come through giving up cigarettes altogether or not taking up the habit in the first place...
...North American Electronics Engineer Edward Flint devised a compact infrared sensor that can be mounted atop a plane. While scanning 45° to either side of the aircraft's flight path, the sensor can detect temperature variations as small as a fraction of a degree Fahrenheit in atmospheric carbon dioxide at a range of from 24 to 48 miles. These variations register on three side-by-side cockpit gauges that show the pilot whether a temperature gradient lies directly ahead or 45° to the left or right of his flight path...
...Beeps. In Viet Nam, the ammonia is produced by groups of perspiring men. Urea, a component of perspiration, is attacked by bacteria on the skin and decomposed into odorless carbon dioxide and ammonia gas. Thus the air in the vicinity of a large group of men-especially in hot and humid climates-contains high concentrations of ammonia. To detect the ammonia, the E63 scoops up air, passes it over a wick saturated with hydrochloric acid and into a humidifying chamber. If the air contains any ammonia, a fog forms, changing the amount of light shining on a photoelectric cell...
...first-week foul-ups was the magnitude of its success. No one had come even close to gauging the fair's capacity for drawing crowds. Indeed, so big and so eager were the early Expo hordes that they did not spin the turnstiles far enough to allow carbon brushes to make the contacts necessary to send electrical impulses to the computers Counting attendance. At one point, officials had to send people down to "eyeball" the entrants. Because of the tangle in counting arrivals, Air Canada had to cancel its plan to reward Expo's 1,000,000th visitor...
