...Russia: The Unfinished Revolution." On the 50th anniversary of the Bolshevik Revolution, NET Reporter Colette Shulman goes to Moscow to take a long, thoughtful look at the strong points and growing pains of the Russians. Included are talks with Poet Andrei Voznesensky, the late writer Ilya Ehrenburg, Nobel-Prizewinning Physicist Igor Tamm and Economist Alexander Birman...
...both a sunset and a sunrise, which occur 59 earth days apart. When it was high in the sky, the sun would appear as a familiar disk-if it could be seen through the murky Venusian clouds. But as it set, according to Stanford University Engineer and Physicist Von R. Eshleman, the disk would gradually diffuse itself around the entire horizon as a glowing band for the remainder of the night; sunlight is so bent, or refracted, by the dense atmosphere that it circles around to the dark side of the planet. At dawn, nearly two earth months later...
...cycle until they liquefy and eventually solidify. As the gases approach absolute zero, a sophisticated magnetization process extracts their remaining reservoir of heat. Because there will always be slight thermal motion of the atomic particles, scientists will never actually achieve absolute zero. But last July, Naval Research Laboratory Physicist Arthur Spohr reported achieving a record low temperature by chilling helium to within a millionth of a degree of absolute zero-3/10 of a millionth of a degree colder than the lowest temperature previously achieved...
...their physics from M.I.T. and their theology from Union Theological Seminary." Another hindrance to exchange is the proliferation of incompatible television systems-a tape produced at one school may not fit the equipment of another. Despite such obstacles, Berkeley is finding off-campus use for its videotapes of Physicist Edward Teller's introductory course. Plans to link campuses by television are proceeding in several regions, including California, New York and Indiana...
...scientists are impressed, and hope to stage similar tests in the Great Plains hail belt. Physicist Byron Phillips, a hail expert for the U.S. Environmental Science Services Administration at Boulder, suggests that inexpensive ; rockets might be even more efficient. Eight rocket stations, he says, could protect the entire state of Kansas...
