Light from the most distant of the external galaxies, when broken up into its component colors by a prism or grating, is shifted toward the red end of the spectrum, indicating that the galaxies are retreating in all directions.* For them, the apparent velocity is roughly proportional to the distance. But among the nearest galaxies, this ratio does not hold. The Milky Way appears to be approaching some, receding from others. To isolate this motion, Dr. Hubble had to allow for and discount the sun's own movement within the Milky Way-since he was perforce using the solar...
...look twice their age. In Wilde's long stage joke of what happens when one young man invents an invalid friend and another young man invents a dissolute brother, there are still pleasant stretches. Lady Bracknell, "a monster without being a myth," is still an amusing snob. Miss Prism is still a funny old maid. And Wilde is still the most brilliant epigrammatist in the modern theatre, though for sustained comic dialogue he cannot hold a candle to Shaw...
...gastroscope is over two feet long. The upper half of the tube is steel and connects with the lower half which is rubber lined with a metal coil. At the lower end there is a flexible guide to ease the tube's passage, a small light and a prism which protrude on one side. Inside the tube, one above the other, are set more than 40 lenses. No matter which way the tube is bent within the patient, the lenses diffract the image at the bottom of the tube so that the physician has a clear view...
Properly impressed by the dramatic fact that people who were children in 1903 had barely reached middle age by the time Franco's bombers were pounding Barcelona, Director Wellman, who helped concoct his own story, tried to reflect the whole bright saga of flying through the prism of a conventional triangle plot. When Pat Falconer, Scott Barnes and Peggy Ranson are moppets, sailing kites in imitation of the airship Peggy's inventor father is trying to rig up in his workshop, the device succeeds brilliantly. By the time the children have grown up into Fred MacMurray, Ray Milland...
...such a simple development-like putting an eraser on the end of a pencil," said Inventor Valentine. Since it costs only $200 to equip a camera with the prism, the price is negligible by Hollywood standards and Mr. Valentine expects that his improvement will come into general...
