...none too soon when news came that Moroccan natives 1,000 strong had risen at Khemisset with knives and guns, were besieging the French garrison which had barricaded itself. Ten planes followed by troops from Rabat forced the Insurrectionists to submit and a French court-martial working at top speed sentenced 70 arrested persons to prison terms of from one to ten years, restored quiet...
...cyclotron of Ernest Orlando Lawrence neatly finesses such troubles by making a comparatively small voltage act on a particle repeatedly until it attains a speed corresponding to extremely high voltage, thus dispensing with a discharge tube altogether. Most conspicuous feature of the apparatus is an 85-ton electro-magnet whose poles face each other vertically across an 8-in. gap. In the gap is placed a shallow cylindrical tank, pumped out to a high vacuum so that particles inside may move freely without interference from air molecules. Ions such as deuterons (nuclei of heavy hydrogen...
...start to move outward. The effect of the big magnet is to pull them in circles. Just as they complete a half-circle the voltage is reversed, so that they get a kick of 50,000 volts to boost them around the other side of the circle at higher speed. After another half-circle the reversed voltage hits them again, and so on. The deuterons go spiraling outward, faster and faster, toward the rim of the tank. After being kicked 100 times by 50,000 volts, they attain speeds of 5,000,000 electron-volts. As they approach...
...bullets. Japanese aircraft, zooming up from a field the Chinese were bombing, got busy in mad efforts to save themselves and retaliate with as much damage to Chinese as possible, proceeded to fly over the neutral foreigners in the International Settlement with full cargoes of bombs, released these at speed over the Settlement, aimed them, of course, to fall in a slanting trajectory on Chinese positions a few yards outside...
...thousand miles of Autobahn (speed-limitless motor roads) have now been built by the Nazis, who continue to open more at the rate of 650 miles yearly, have projected a total of 4,500 miles...
