Stare, who stepped down as chairman this year under a School of Public Health ceiling on the age of those performing administrative duties, sees no danger that his concern with raising money for the department might color his writing, teaching and testimony on nutrition. All corporations can expect from him, he says, is the truth...
...science and language courses where lectures are devoted to special presentations and discussions peripheral to the course matter, a single text may be the sole source of information on a subject. In the less exacting social science and humanities courses, a book selling a certain point of view may color and distort a student's perspective in a field to which he plans to devote his entire life. Despite all the sneers, chuckles and snide remarks from students who discover their professor's books on the list, the books penned by course teachers--whether required or supplemental--always leave empty...
...laymen. Yet recently two University of Illinois mathematicians announced a breakthrough of such widespread interest that even the reticent American Mathematical Society issued a rare press release. The news: after more than a century of futile brain racking, one of mathematics' most famous teasers-the so-called four-color conjecture-has finally been proved...
First stated in 1853 by a London graduate student named Francis Guthrie, the conjecture is simple. It says that no more than four colors are needed to shade any map so that no two adjoining countries are the same color. Though the experience of countless cartographers over the years supports the truth of this statement, mathematicians have never been able to prove it for all cases. Hence there remained the gnawing feeling that there just might be one instance where, say, five colors were needed instead of only four. Indeed, when Scientific American's puckish columnist Martin Gardner last...
...least one of 1,936 basic forms-or, in the jargon that helps keep mathematics mysterious, reducible configurations-that they had identified. Then they fed the forms into a computer and asked, in effect, whether all possible maps containing these configurations could indeed be made with only four colors. The electronic brain wrestled with the question for some 1,200 hours, during which it made some 10 billion separate, logical decisions. Finally the machine replied yes, and the four-color conjecture turned from theory into fact...
