Nevertheless, however impractical it may sound at times, the yearning for a United States of Africa is real. Last month's creation of the Mali Federation -loosely encompassing the four former French territories of Senegal, the Voltaic Republic and the Republics Dahomey and Sudan-seems likely to be the pattern of things to come. The tide now running in Black Africa is toward independence, regional groupings, and a sort of African authoritarianism that pays its respects to Western democratic forms but rests on older habits of strong rule...
...proper for a democracy, is it not?" The "best seat" is a living room sofa facing a wall equipped with two speakers six to eight feet apart. If listener and speakers are positioned correctly, there seems to issue from the wall a wave of what is known as stereophonic sound. Nothing has so excited listeners and record makers since, more than a decade ago, the long-playing disk ushered in the Age of High Fidelity. Stereophony's extra clarity and depth have not had the immediate impact on the public that high-fidelity sound...
...most record buyers were concerned, just a year ago stereo sound was little more than a whisper in a laboratory echo chamber. By the beginning of this year, the stereo disk (usually $1 more than a comparable monophonic) accounted for roughly 10% of total LP sales; by year's end, it may represent a third of the total. But stereo disks are not likely to make the old monophonic disks entirely obsolete, since a well-engineered old-style LP sounds fine when played on stereo. While the sale of monophonic equipment has dwindled to almost nothing, many...
...Equipment. Stereo disks are made by feeding sound through three or more separate microphones, with the signals recorded on three separate channels that are later reduced to two. On the record, a single needle picks up separate impulses from each channel by moving both up and down and sideways in a single groove. The two signals from the needle must be played through two separate amplifiers and speakers. Despite the necessary additional equipment, the cost can be far lower than that of a genuine monophonic hi-fi rig, because stereo achieves impressive reproduction with relatively small speakers and low-wattage...
...already cluttered American living room, manufacturers also offer "self-contained stereo"-units with both speakers housed in a single cabinet. But two-speaker cabinets, unless they are six to eight feet long, can give only an illusion of stereo depth and definition (what one manufacturer calls "stereotype" sound...
