...GHETTOS are now leading the movement to reform urban education, but the awakening snarl of the core-city has obscured the growing power of a very different type of reformer: the educational academic. Though ghetto residents hold no affection for their cloistered allies, the two communities are linked by the logic of reform. Harried politicians run from encounters with angry ghetto voters to cry for help in the arms of academics. This winter's Harvard Educational Review lets the layman eavesdrop on what those experts are telling each other, and what they are probably telling their worried political friends...
...Hard-core U.S. sports buffs might scoff at the game of curling - that is, if they've even heard of it. Imagine grown men playing a sort of shuffleboard on ice, with brooms and a big rock. One man slides the rock down the ice and his teammates charge ahead of it, sweeping furiously as it approaches a series of concentric circles with a bull's-eye in the middle. Even the name sounds slightly nutty. Wasn't that something women did to their hair...
...ridges and faults associated with earthquake activity. Furthermore, most of the 19 points on the earth's surface where three Rouse belts intersected coincided with areas of major earthquake or volcanic activity. Significantly, the planes of the belts passed through the boundary between the earth's molten core and its solid mantle, each being approximately tangent to the core...
...What causes the stress in the plane of a Rouse belt, resulting in quakes, volcanism and mountain building? In the Mines Magazine, the Colorado scientists suggest that both interplanetary and glactic magnetic fields interact with the earth's magnetic field, thus tugging on the earth's iron core. But the core is prevented from responding to extraterrestrial magnetic pull by the inertia of the rotating mantle that surrounds it. The resulting conflict sets up stresses in the boundary between the mantle and the core that are released in planes tangent to the core...
...rudimentary demonstration of their theory, Rouse and Bisque used children's Modeling Dough to mold a mantle around a solid core. The core was attached to a spindle that the scientists used to spin their model earth, accelerating it to simulate the effects of tugging magnetic fields. When the modeling compound dried and formed a thin crust, its larger cracks clearly defined major stress planes that were tangent to the core...
