Despite neat formulas and equations in textbooks, chemistry is still an inexact science. At best, scientists only partly understand some of the turbulent processes that occur during chemical reactions; often they cannot accurately predict the end results. Now a California scientist has devised a method for making chemistry more exact: he mixes chemicals in a computer instead of a test tube...
Compounding the confusion, marijuana itself is an inexact term. All marijuana comes from the female hemp plant, Cannabis sativa, which grows worldwide. As the plants ripen, their flower and seed heads exude a resin that contains the highest natural concentration of active cannabis chemicals. The pure resin is hashish, a combination of powerful chemicals. Hashish, by Giordano's own testimony, rarely reaches...
Yale's action reflects a widespread dissatisfaction over trying to apply numbers, or letters with pluses and minuses, to something as inexact as student performance. Explained Professor William Kessen, chairman of the committee that recommended the changes: "Whether a man gets a 72 or a 74 just doesn't reflect his performance, his knowledge, or anything." The new system, however, presents Yale students with one potential problem: in competing for entrance to graduate schools, they will have neither class rankings, nor point averages to present, will have to depend heavily on faculty recommendations and interviews...
Their Pleasure. The two ads are effects of the same trend: the pleasure reserved for adults is more and more a woman's pleasure as well as a man's. Of some 65 million U.S. women over 18, probably six out of ten, by the inexact statistics of the liquor industry, drink at least occasionally. That represents a one-third increase in women drinkers in only ten years. Moreover, women now make about 45% of all liquor purchases, usually for the family. To win over to particular brands this rising number of sippers and shoppers, the industry...

The pollsters, of course, point out that the two differing polls were taken at different times by different methods, but their appearance in the same week is proof that polling is an inexact and erratic procedure. The pollsters have become so entrenched on the political scene in the past few years, snaps Maryland's Republican Representative Charles Mathias, that "they've reached a position where they're almost a new kind of priesthood." Last week's results fed an increasing skepticism about the value and methods of the polls...
