Those who detect a pervasive, low-grade child-aversion in the U.S. find it swarming in the air like pollen. They see a nation recoiling from its young like W.C. Fields beset by Baby Leroy. Of the 50,000 parents who responded to a query by Advice Columnist Ann Landers a while ago, a depressing 70% said...
...time as well. The number of learned papers on general relativity has risen from only a handful a few years ago to some 600 or 700 a year. The relativistic revival can also be seen in the spirited competition by scientists around the world to be the first to detect the gravity waves, which, Einstein said, are the vehicle by which gravitational force is transmitted, just as light or radio waves are the carriers of electromagnetic force...
...impossible to detect. Putting the theory into elegant mathematical form, the Dutch physicist Hendrik Lorentz added another idea: permeating the structure of all matter, the ether would also slow down clocks traveling through it?in fact, just enough so light's speed would always seem constant...
Einstein boldly disregarded the notion of the ether. Then he went on to state two postulates: 1) An experiment can detect only relative motion, that is, the motion of one observer with respect to an other. 2) Regardless of the motion of its source, light always moves through emp ty space at a constant speed (this seems to violate common sense, which suggests that light projected forward from a moving spacecraft, like a bullet fired from a plane, would travel at a speed equal to its velocity plus that of the craft). From these statements, using thought experiments and simple...
...personnel will tour non-residential buildings to detect any trouble early. "When buildings are unoccupied, over the weekend, we're much more vulnerable," Norman Goodwin Jr., B & G utilities manager, said yesterday...
