Despite its brevity, the life line of the lightning flash has been accurately measured by the cathode ray oscillograph. This is an instrument developed by the General Electric Company at Schenectady and makes use of a beam of electrons which, acting as a pointer, measures- the rise & fall, or wave shape of the voltages. When a wave of lightning encounters an obstruction it builds up to twice its power, just as a wave of water breaking on a wall will splash about twice its height. Therefore a direct voltage of 3,000,000 traveling along a line will suddenly jump...

Coolidge Tube. In x-ray tubes the electrons popping from the cathode are imprisoned within the tubes. How to get them outside became a problem for scientists. Philip Lenard, Nobel prizewinner for 1905 and now professor at the University of Heidelberg, solved it by placing a thin aluminum "window," one eighth of an inch in diameter, at one end of a tube. Electrons passed through it, but feebly. He used only 30,000 volts of electricity...

Lloyd Hahn, runner, had not lost a race for two years. Last week in Kansas City Ray Conger beat him and beat his record for 1,000 yards with a time of 2:11. Hahn stopped running. He walked to the tape with a disgusted expression and said that Conger stuck an elbow in him at the turn. None of the officials...
