...hours later 20,000 people seated in the stands of the State Fair Grounds heard Miss Agnes Samuelson, State Superintendent of Public Instruction, introduce Alf Landon. The candidate however was nowhere to be seen. Suddenly great spotlights sought out the west gate of the race track. Riding down the beam came Alf Landon in the tonneau of his car, waving to the crowd. In a moment he was on the platform. When a five-minute demonstration had subsided he began...
Thus Dr. Fermi holding a ball of paraffin in his hand symbolizes a matter of immense importance to biology. Organic substances are rich in hydrogen. Professor Ernest Orlando Lawrence of the University of California, whose huge apparatus produces a beam of 10,000,000 neutrons a second, finds that on the white blood cells of rats neutrons exert ten times the destructive effect of X rays of equal intensity. As laid down last month in the American Journal of Roentgenology and Radium Therapy, the biologic neutron problems now confronting science are these...
...possible, the engineers were soon told, because the "windshield" through which they looked was made of a recently developed material called Polaroid, and the headlight lenses were backed by plates of the same stuff. Polaroid polarizes light. Reduced to simplest terms, polarization is a process of "combing out" a beam of light so that it vibrates in one plane only. Laymen understand polarization more readily if they imagine that a beam of light, vibrating in all directions, is a flight of straws blown along helter-skelter by the wind. If the straws collide with a picket fence, some will pass...
...laboratory practice, a light beam's "fence" is a crystal, and the gaps which comb light are a crystal's parallel planes of cleavage. Polaroid is a suspension of crystals. The dazzling headlights at last week's demonstration were dimmed because the Polaroid in the lenses and in the windshield was aligned in conflicting directions. The light could thus pass through one but not through both...
United's system embodies no new principle, is merely a new combination of two well-known mechanisms - the robot pilot and the landing beam system designed in 1933 by the Bureau of Air Commerce. As the plane approaches the airport, it leaves the flying beam and picks up two new beams by means of a special cross-shaped antenna on the plane's nose. One of these is a vertical directional beam about five feet wide at the airport. The other is a lateral, curved landing beam which slants down onto the field from one side, almost vertical...
