Cinemascope uses a distortion and rectification principle: a wide-angle distortion lens fitted to a regular 35-mm. movie camera produces distorted images on the film; a compensation lens, fitted on a " regular out the 35-mm. images movie on the projector, screen. "straightens" out the images on the screen...
...Speed Camera. University of California scientists described their new camera that needs less than a three-millionth of a second to click off a single picture. Unlike conventional motion-picture cameras with moving rolls of film the U.C. camera has two stationary strips of film and a bank of lenses. A thin mirror, spinning at 10,000 r.p.m., flashes the moving image from lens to lens down the film strips. As many as 100 snapshots can be taken in 1/120,000th of a second. Probable purpose of the superspeed camera: to photograph the luminous, super sonic shock wave from...
Conventional spectacles, Dr. Feinbloom explained, are simply magnifying glasses with lenses shaped like part of a sphere. No matter how much they magnify, they do not have enough "resolving power" to project a sharp image on the retina (the screen at the back of the eyeball) if the retina is damaged. Most partially sighted patients have retinas like a coarse-grained photographic plate: they can record a sharp image only if they are fitted with a lens of unusually high resolving power...
...student has three alternatives. If he brings his complaints to the Hygiene Building, he is steered toward a list of Boston optholmologists. These men have M.D. degrees, and may be of help of those with eye disease, but most students just need a power increase in their present lenses--so optholmologists are an expensive luxury. He might instead patronize the handful of opticians around the Square. Here, however, the student is helpless before the log-rolling collusion of examiner and lens grinder. This combination rarely fails to produce bills of less than twenty dollars...
Tuataras are not only ancient, but odd. They have three eyes, one in the middle of the forehead. In humans, who may be descended, like the lizards and snakes, from something very like a tuatara, this third "pineal" eye has become the pineal gland deep inside the head. The tuatara...
