...Players' excellent production gives them just the right sense of serene, oblivious seriousness--like the hint of a flute obligato at the first entrance of an almost entirely irrelevant character called Mad Margaret, or the "Alas, poor ghost" with which the hero, for no reason in particular, greets his spectral uncle...
...about the size and character of the nucleus). M.I.T.'s Haystack Radio Observatory will try a similar experiment in reverse: it will study radio waves from a far-off radio source (possibly a quasar) after they pass through the comet's tail, in hopes of finding the spectral "signatures" of water or ammonia. If they succeed, the M.I.T. astronomers will have gone a long way toward confirming Whipple's icy-snowball theory...
Some other experts consulted by TIME are confident that the skills of scientists in detecting tape alterations run well ahead of the talents of all but the most ingenious tamperers. Particularly through the use of spectral analysis techniques, in which various sound frequencies on a tape can be separated and studied, these experts believe that any heavy handed deception can be exposed...
...scientists at the University of Arkansas reports in a paper that "any alteration of the White House tapes could be detected in a timely fashion." The ear can be fooled and so can the oscilloscope (a device that can depict sound waves as electronically-generated graphs). But the spectral analysis may well determine whether a given recorder produced a specific recording, whether a tape has been cut or edited, whether it is an original or a copy. Any change in microphones or acoustical conditions would be suspect. Since a recorder gradually heats up as it plays, any sudden shift...
...Athens, a city where "everybody knows everybody else," almost everybody has heard of Brigadier General Dimitrios loannidis (pronounced Ee-o-ahn-ee-dis). A spectral, Beria-like figure who commands Greece's military police force-the feared ESA-loannidis was not seen by the public even at the swearing-in ceremony of Phaedon Gizikis, the colorless army general who is Greece's new President. He did not really have to, since it is loannidis and not Gizikis who runs the junta...
