...more from the recession and a falling off in the import of heavy capital equipment from the U.S. than from any government action. The Tories, who succeeded in their 7 4-months in office in doing something for almost everybody, will ask the Canadian voters for a parliamentary majority solid enough to ensure them the usual four years in power. As the campaign opened, they seemed to have a better than even chance...
...County Superintendent Jim Cherry: "Less than half the white children in Georgia are completing the present high school program. Less than 20% of the Negroes graduate. A great majority of high schools offer no chemistry and physics, and others offer it only in alternate years. Advanced algebra, trigonometry and solid geometry are not available in the great majority of Georgia high schools. Science and libraries are limited. Vocational courses such as mechanical drawing and mechanics are not available...
...theater at Manhattan's projected Lincoln Center for the Performing Arts, the Metropolitan Opera is busy with another building program. Aside from the great names on its roster-Maria Callas. Victoria de los Angeles, Richard Tucker, Mario Del Monaco, Leonard Warren, Cesare Siepi-it is adding to its solid second rank by bringing in exciting newcomers who, more than the established stars, are making this a memorable season. Some of the best of the new voices...
...pupils to the new things they have learned. But the major lesson of the Portland project is that if more cities do not do something similar soon, U.S. teachers will find themselves dismally unprepared for a curriculum in which the barriers between algebra, geometry and analysis are crumbling, solid geometry and trigonometry may disappear as separate subjects, and algebra will deal with such topics as groups, rings and fields. As one Portland student put it: "Even the concept of the line has changed. In geometry you may have learned that a line is the shortest distance between two points...
...When deuterium atoms get hot enough, they hit each other so hard that they "fuse," forming helium 3 (and a neutron) or tritium (and a proton), and give off energy. This process happens explosively in H-bombs, but to control the reaction, the deuterium must be confined. Since ordinary, solid walls cannot hold the gas at the necessary temperature of many million degrees, fusion reactors use walls of magnetic force. They are strong, do not cool the gas and are not damaged by it. But the machines' complexity proves that magnetic walls are hard to handle...
