TECHNOLOGY: In his State of the Union message Nixon proudly described a new program in which the Government will cooperate with private industry in developing a series of ultrahigh-technology projects to "improve our everyday lives." These include new mass transit systems and fire-fighting techniques employing helicopters. Unfortunately, Nixon had more new ideas than new funds: the Government will spend only a modest $700 million on new civilian research programs in 1973, with another $800 million going to military research...
...generated in much the same manner as the beam inside a home TV picture tube. Injected into a nickel-size hole that runs the length of the copper tube, the beam's electrons are immediately accelerated by 6,000,000-watt microwave pulses generated by 245 klystrons-giant, ultrahigh-frequency radio tubes spaced evenly in the structure above the entire length of the tunnel. Riding the crest of the moving radio wave produced by the klystrons, the electrons move only a few feet before they approach the universal speed limit-the velocity of light...
...ultrahigh-frequency television stations that are gradually spreading across the country may be reaching an unexpected audience. UHF transmissions, says Institute of Electrical and Electronics Engineers President Bernard Oliver, may have already provided the first evidence to extraterrestrial civilizations that intelligent, or anyway TV-producing life exists on earth...
...named the Texas Broadcasting Corp., renamed the LBJ Co., then changed back to Texas Broadcasting after Johnson became President. It has expanded considerably, now includes real estate holdings and shares in other broadcasting companies. In 1954, when Lyndon was Senate minority leader, the Johnsons bought KANG, a foundering UHF (ultrahigh frequency) television station in Waco. The FCC had just given a VHF license to a proposed Waco TV outlet, KWTX. CBS, which had been negotiating with KWTX, quickly decided to award its contract to KANG instead. Shortly thereafter, so did ABC. Then, with FCC approval, the Johnsons increased the transmitting...
...often occurs where two air masses, moving in opposite directions, grind together. Unlike storm fronts, which present a large, moist target for regular storm-tracking radars, this abrupt change of wind direction, or "wind shear," usually goes unremarked by electronics. Last year RCA technicians tracking swift Army missiles on ultrahigh-frequency (above 5,000 megacycles) C-band radar noticed that they were receiving considerable "backscatter"-unexpected, and apparently unexplainable, echoes-during a clear-sky exercise. They wondered if they were on the track...
