...probability of particle interaction. Even more important, circular accelerators cannot impart energies of more than about ten BEV to electrons which radiate away much of their energy when traveling in a circular path. Synchrotrons and other circular accelerators such as cyclotrons and betatrons are usually used to accelerate much heavier particles such as protons and deutrons...
...only the second time in the air war, the MIGs cut loose with air-to-air missiles-two Russian ATOLLs, rockets similar to the U.S. heat-seeking Sidewinder. They fared no better than the SAMs: both missed, and the MIGs fled, despite their tactical superiority over the heavier F-105 in air combat...
...tuck back at high speed and open out for landings. Called the Boeing SST 733, it could achieve the same speed and stratospheric altitude as Lockheed's 2000. Boeing is building a mockup, plans to display it around September. The plane has just undergone major modifications, making it heavier (300 tons v. Lockheed's 250 tons), longer (298 ft. v. 273 ft.) and more capacious (300 passengers, six abreast instead of five...
Rheumatic disorders vie with the various heart diseases as a cause of handicapping illness, and they are second only to mental illness as a cause of lasting disability. They take a heavier toll of work days lost in industry than do accidents. Even so, total U.S. outlays for arthritis and rheumatism research come to little more than $15 million a year-as against $300 million poured down the drain in desperation for quack "remedies," ranging from diets to sitting in old uranium mines, from bee venom to honey and vinegar. The troubles are classified in four major groups...
...highest energy), they aimed a beam from the grating through a Pyrex cylinder containing hydrogen and deuterium iodide gas, which breaks down when exposed to light. When molecules of deuterium iodide were struck by photons in the light beam, they split into fast-moving atoms of deuterium and sluggish, heavier atoms of iodine. Some of the speeding deuterium atoms in turn collided with hydrogen molecules in the cylinder, knocking off one of the hydrogen atoms and combining with the other to form deuterium hydride...
