...task of exposing the claims of speed reading quacks. First of all, even though such things as the fixation time could be reduced in practice by ten per cent, the carryover to natural reading situations was disappointingly small. Also, it was shown that the part of the retina sensitive enough to see the printed line can accommodate clearly only about one-half inch of any printed line. Optometric research has proven that letters one-half inch from the exact point of fixation are seen with only fifty per cent acuity. (In 1951, John Kennedy rounded...
...English estimation than Sir John Gielgud and Sir Laurence Olivier. Lady Redgrave, who plays as Rachel Kempson, is accounted a superb supporting actress. And over the last year a new generation of Redgraves, who might well be known as "Michael's bloody marvels," has spangled the marquees with a retina-rocking glitter of new talent. Corin, 27, played his first big part (Sir Thomas More's son-in-law) in a big picture (A Man for All Seasons) and charmed the critics with a witty portrait of a political noddy. Lynn, 24, hit the top with a gloriously vulgar clang...
Seldom in these days of coast-to-coast screens and retina-wrecking color is a play so tastefully transformed into a film. Scene after scene is played in sober old Tudor houses glozed by candlelight, or by the warm green verges of the New Forest. The costumes are rich, not gaudy, and the actors are borne lightly on the lucid stream of language that flows throughout the film. Even more mesmerically than he did in the play, Paul Scofield pulls all eyes toward himself by the abundance and subtlety of what seems to be happening inside him. Seen close...
...professors is whether subject or student comes first?and the verdict usually favors those who stress the subject. Harvard Biologist George Wald, 59, shows why. As a researcher, he has made one of the most enlightening finds of recent decades: his discovery of the Vitamin A molecule in the retina goes a long way toward explaining the physiology of eyesight. Light, it seems, makes this crooked molecule straighten out and signal the optic nerve. The very originality of such work also makes Wald a frontiers-of-research lecturer, and his "Nat Sci 5," in the Harvard Crimson's judgment...
Using his new method, Wald and his associates were able to examine the pigments without removing them from the human retina. Eventually, the experimenters were able to measure the pigments in single light-sensitive cones of the retina, Wald said...
