Conceived in 1941 as a way for the deaf to "read" speech, the voice-print machine analyzes patterns of frequency and amplitude, transcribing each variation into a spectrogram. One of the chief developers, Physicist Lawrence Kersta, claims that everyone's voiceprint is as unique as his fingerprints, and that any skilled technician can identify a voiceprint with more than 99% accuracy. Other scientists have disputed his claims...
...Government began drastically cutting back on its large wartime orders from Haloid, and Wilson started a search for new products. His chief of research. Dr. John Dessauer, showed him a 25-line abstract in a Kodak company journal describing a dry copying process that had been invented by Physicist Chester F. Carlson in the 1930s but never commercially developed. Wilson studied Carlson's equipment-which had been unsuccessfully offered to Kodak, A.B. Dick and IBM-then decided to buy the rights...
Gravel's motion arises from a grand jury subpoena served on Leonard S. Rodberg, a physicist at the Institute for Policy Studies whom Gravel hired as an administrative aide to help publish his edition of the Pentagon study...
...have sought to disprove it. They have even used the paradox in an effort to challenge all of relativity; for Einstein himself admitted that if only one part of his theory proved wrong, its whole finely structured mathematical edifice would crumble. In the September issue of Physics Today, Physicist Mendel Sachs takes a different tack. He contends that the Einstein theory and equations are correct, but that Einstein misinterpreted the equations in stating the clock paradox. A relativity theorist himself at the State University of New York in Buffalo, Sachs argues that the equations suggest that the difference between...
...concept was developed by Physicist John S. Rinehart of the National Oceanic and Atmospheric Administration, who has been comparing the past activities of Old Faithful and two other famous geysers-Yellowstone's Riverside and Old Faithful in Calistoga, Calif.-with earthquake records dating back more than a century. He found that although geysers are commonly thought to erupt with clocklike regularity, their timing begins to change as the stresses that lead to quakes begin increasing in the earth around them; Yellowstone's Old Faithful speeds up any time from two to four years before a major quake within...
