...grow. Now even Deryagin has washed his hands of polywater. In a recent scientific paper, reports Chemical & Engineering News, the Soviet researcher admits that it is nothing more than ordinary water contaminated by silicon. Where did the silicon come from? Apparently it was picked up in the hair-thin quartz tubes that he and other scientists used to produce the stuff from condensing water vapor. Comments Chemical & Engineering News...
...negotiation between the Chinese and French governments, begun by ex-Culture Minister André Malraux and finished in detail by a group of orientalists headed by Vadime Elisseeff, chief curator of the Musée Cernuschi in Paris. Encyclopedic in scope-the objects on display range from rudimentary quartz and flint scrapers used by Peking Man in 500,000 B.C. to the exquisite porcelains and silver toilet articles of the Yuan dynasty, which ended in A.D. 1368-it is intelligently mounted, with unobtrusive panels of photos, documents and information: an ideal teaching show, in fact. But unlike most didactic exhibitions...
...Bronze Age artists used a curious technique; with a tool made from hard rock, possibly quartz, they hammered or scraped groups of closely spaced small holes, 1 mm. to 5 mm. in diameter. Significantly, the most painstakingly executed samples of valley craftsmanship are found in the earliest engravings. Later artists were content with fewer and larger holes, and their work became blurred and uneven...
There are a number of disadvantages to quartz watches. They must be returned to the factory to be serviced or repaired, and they are not shockproof. Some, like the Timex, are bulky. Quartz watches are selling regardless, but they are expected to remain too costly for many years to compete in the low-priced market, which accounts for most of the sales. Four-fifths of all watches marketed in the U.S. are priced under $40, while only one out of 20 costs $ 100 or more...
...canny Swiss, while expanding in the quartz field, are moving to get a bigger hold as well on the low-priced market. Tissot is test marketing a lightweight watch under another brand name made almost entirely of mass-produced lightweight, durable plastic parts, and selling it for about $20. Pierre Waltz, president of one of the biggest Swiss horological groups, proudly wears a plastic watch, and he says, "This might be as important a development as the electronic watch." Because the plastic case is sealed and cannot be opened for repairs, the new product will be the industry...
