...Pathologist Coleman de Chenar said that it was "certainly not the cause of the headaches" and "could not have had any influence on his psychic behavior." A number of Dexedrine tablets?stimulants known as "goofballs" ?were found in Whitman's possession, but physicians were not able to detect signs that he had taken any before he died...
Newtonian or Quantum? After exposing the cylinder to light of a uniform wave length for periods ranging from half an hour to ten hours, the scientists analyzed its contents to detect molecules of deuterium hydride. The process was repeated, each time with a light beam of longer wave length and lower energy, until they failed to find molecules of deuterium hydride in the cylinder-no matter how long the gases had been exposed to the light. At this particular wave length, it seemed clear, the deuterium atoms had not been given enough velocity to split the hydrogen molecules and combine...
...better solution than the uncertain safeguard of self-regulation would be the bill now before Congress authorizing the Secretary of Commerce to set mandatory minimum safety standards. The customer himself can hardly detect weak door latches or lance-like steering columns whose deadlines might show up only in a crash. But federal inspectors could locate the hidden killers and require manufacturers to eliminate them. Just as significantly, the government could insure continuing progress in automotive safety by demanding that technical innovations such as the collapsible steering column be installed as soon as they are developed. Then foot-dragging on features...
With a surface machined to within a tenth of an inch, the new dish will also greatly broaden the range of radio wavelengths which the telescope can detect...
Radiation from charged pairs of carbon and hydrogen atoms. Lilley said, could be especially significant. Finding evidence of this material could indicate that vast quantities of organic compounds are being formed naturally in space. So far, however, astronomers have been unable to detect such radiation...
