...Tandem Tubes. To get gamma rays to rush as fast from his tube as they do from radium, Dr. Coolidge would need about 2,000,000 volts of electricity. To get beta rays as penetrating as those from radium, he would need 3,000,000 volts. If he could create such voltages and if he could direct them properly, he would be, according to Philosopher Henri Bergson, at the heart of the world. Dr. Coolidge has succeeded in using 900,000 volts effectively. How he worked, he described to the engineers at Manhattan last week after receiving his latest medal...
...joined three of his vacuum tubes in tandem and in the connecting necks placed hollow metal cylinders. From a tungsten filament cathode in the first tube, 300,000 volts of electricity shot cathode rays into the first metal cylinder, which functioned as anode to the first and cathode to the second. There 300,000 more volts kicked the speeding electrons into the next similarly acting cylinder, where 300,000 more volts gave a final kick. The rays cascaded out of the apparatus at 175,000 miles per second-almost as fast as light, 350,000 times faster than a rifle...
...natural cavalryman. Theodore Roosevelt resigns to organize a volunteer corps. The Rough Riders gather in San Antonio-cowboys, jailbreakers, sheriffs, wealthy young clubmen from Manhattan. Ladies in long skirts, with trim shirt-waists that betray an underpinning of steel corsets, straw-hatted, ride to the scene of mobilization on tandem bicycles. Among them is Mary, "San Antonio belle and sweetheart of the regiment" (Mary Astor). For her love, poor timid, countryboy, Bert Henley (Charles Emmett Mack), and wealthy Manhattan clubman, Stewart Van Brunt (Charles Farrell), rival, quarrel, then fight. Their private scrap is too puny, decrees Colonel Roosevelt. Let them...
...extraordinary athletic event is scheduled for sometime in the near future in the form of a Tandem bicycle race. Not only is this unique contest unprecedented since the days of the "high wheelers," but it will determine the supremacy, in this particular activity, between the college and the graduate schools...
...fabric-covered, are also metal in their structure. Two huge Packard engines of 800 horsepower each revolve at 2,200 times a minute-hence their large power for comparatively small weight-while the propellers are geared down and therefore work more slowly and efficiently. The engines are placed in tandem, with a propeller at front and rear end. Thus, if one motor ceases functioning, there still remains sufficient power to sustain flight, and there exists no dangerous tendency to slew the airplane violently around-as is the case when there are two motors, one on either wing. Nothing illustrates progress...
