Children usually find orthodontics* easier than do adults, as their growing bones are more malleable. What many adults suffer from is the tendency of teeth to shift after a few have been removed because of decay. The shift changes the bite, and this in turn may lead to erosion of bone as far back as the hinge of the jaw. Just as damaging in the long run, is the weakening of the gums that results from a bad bite. Far more adult teeth are lost to gum and bone disease than to decay, dentists...
...Charlestown, the Cattons detect "a faint but undeniable whiff of decay" under the city's genteel tradition." Brierfield, Davis's estate, is said to have been in the Scarlett O'Hara tradition, and governors' messages are said to have "popped and rattled across the Gulf states like a chain of firecrackers." The authors also claim that "no two men in all the nation held views about the [Kansas-Nebraska] crisis with firmer conviction than did Abraham Lincoln and Jefferson Davis." And to everyone but the reader, "it was obvious, from almost every angle, that the [1860 Republican] party...
...tragedy, and his works are both noble and enervating. Since he does not believe in life after death, he cherishes existence as a singular event: he is a fatalist taking arms against despair. "Life itself is a tragic thing," he says. "We watch ourselves from the cradle, performing into decay. Man now realizes that he is an accident, a completely futile being, that he has to play out the game without reason...
...echoed by James M. Dunning '26, assistant clinical professor of Public Health Dentistry and director of the University's Dental Health Service. Dr. Dunning, who serves as vice-chairman of the Citizens' committee, maintained that the value of fluoride in preventing tooth decay is "very, very great when it has had time to show its effects." He added that there is no danger in a one part-in-a-million concentration of fluorine in Cambridge's climate, although he acknowledged that about 15 per cent of children, who are raised on fluoridated water develop mottling--"inconspicuous" white spots on their...
...obvious on a macroscopic level and has been verified on an atomic level. Physicists tacitly assumed that parity conservation also held on the subatomic level. In 1957 an experiment was performed which showed that parity was not conserved on the subatomic level. (The electrons emerging from the radioactive decay of cobalt were spinning more in one direction than in the other.) Physicists had assumed a law to be true in a situation where they had no right to. This was the second such faulty assumption which has been corrected in the twentieth century. Until 1926 physicists assumed that Newtonian mechanics...
