According to an early theory, the strain may have been caused when the mild Hog Flu virus, which sickened hogs but not humans, combined with a relatively harmless bacillus to produce a virulent man killer. But in 1918, 25 years before the electron microscope made it possible to see viruses at all, there was no way to discourage advances from the Spanish Lady. Paranoia often took the place of ineffective remedies. There were those who thought the bug was the Kaiser's secret weapon, despite the losses his own troops suffered. In Poland, the source of infection was said...
...bulky picture or cathode-ray tubes used in conventional TV sets, a beam of electrons originates in the stem of the tube and sweeps rapidly to and fro across the tube face. Its intensity is controlled by the signal from the TV station. As the beam hits dots of phosphorescent material in the tube face, they glow with a brightness proportional to the strength of the beam. This rapid action produces at least 25 still pictures per second on the screen, creating the illusion of moving images. In the new Westinghouse system, the images are also formed by producing glowing...
Tentatively called a "J" particle by Ting's team, which used the 33 billion-electron-volt accelerator at the Brookhaven National Laboratory, and a "Psi" particle by Richter's group at the two-mile-long Stanford Linear Accelerator, it was the heaviest atomic fragment ever found-almost 3% times more massive than the proton. It was also, by nuclear standards, extremely long-lived. It survived a full one-hundred billionths of one-billionth of a second, or 1,000 times longer than other massive particles...
Prior to that time, cells were still largely scientific terra incognita. By using the electron microscope, which had recently been developed, Claude taught scientists to explore these miniature worlds and to map them. He also developed techniques for separating cell components in a centrifuge in order to help determine their functions...
...stereo system is so effective that the Canadian subsidiary of Britain's Cambridge Instruments Ltd., the world's leading manufacturer of scanning electron microscopes, plans to market the Chatfield 3-D adapter in the near future for about $6,500 (the microscopes themselves run from $40,000 to $80,000). Chatfield's new technique might even be based on a bigger scale-as the basis for 3-D television...
