...under the rim of the hull, and emerges in jets that point inward, forming a kind of wall. Inside this wall a cushion of air builds up and lifts the Hovercraft off the surface. Forward propulsion is obtained by diverting part of the air flow through horizontal ducts (see diagram...
...Alamos' plasma thermocouple, the solid metals of a bimetallic thermocouple are replaced by a tiny (finch long) rod of uranium suspended inside a vacuum-sealed can that contains liquid cesium. The uranium is enriched with U-235. Around the cesium is a circulating coolant (see diagram). When the device is lowered inside a reactor, the uranium is bombarded by the neutrons generated by the reactor, causing the U-235 to fission and give off intense heat...
...shoot, bossed by the National Aeronautics and Space Administration, worked almost exactly as planned. The launching vehicle was a Chrysler-built Army Jupiter beefed up with extra fuel for extra range. Mounted on its massive shoulders were 15 small, solid-fuel rockets arranged to fire in three stages (see diagram). Perched on the nose of the final rocket was the gilded cone itself, Pioneer...
...words to the President of the U.S., then gave him the lapel pin worn by 40 finalists in the 18th annual Westinghouse Science Talent Search. Minutes later, unflustered by the company he had just kept, John Seymour Letcher Jr. sat jackknifed in a bus seat, lost in a scientific diagram he was sketching. Next day Letcher, who had won his Washington trip by building a particle accelerator, learned that he had won again. His prize: the $7,500 top award in the Westinghouse contest...
...r.p.m. The spin made it act like a gyroscope, keeping its axis always pointing in the same direction in space. At its perigee, the axis is parallel to the earth's surface. But a quarter of a revolution later the axis points vertically at the earth (see diagram). At apogee, the axis is parallel again...
