...Night (Ealing-Universal) is an unusual, British-made thriller which Universal is hawking in the U.S. with an unusual ad campaign. "The everyday phrases and superlatives of ballyhoo," say Universal's ballyhoo experts, "are completely inadequate to capture the mood, the depth, the excitement of this oddly stirring motion picture...
University students will have an opportunity to break into motion pictures next week, when March of Time photographers go into action on a forthcoming scientific film at the Semitic Museum. The shooting was originally scheduled for this morning but was postponed last night...
...tumult set a yeasty, young Assistant Naval Secretary named Theodore Roosevelt in motion. Spain's best colony, he reasoned, was not in the Caribbean. It was practically under the guns of Commodore George Dewey's Pacific Fleet. Promptly, and without any authorization, Teddy Roosevelt ordered Dewey to attack the Philippines if war came. Dewey's response was an overwhelming victory. Suddenly, although nobody yet realized it, the U.S. had an empire...
This assumption was the heart of Relativity. When properly developed, mathematically, it led to astonishing conclusions, some of them (like many scientific facts) "contrary to common sense." Suppose, for instance, that the earth is moving at many feet per second toward a star. This approaching motion does not increase the arrival speed of the star's light, which strikes the earth at exactly the same speed (186,000 miles per second) as if the earth were at rest. Expressed in an equation, it looks like this...
...even Relativity does not abolish simple arithmetic. Einstein's daring conclusion was that only the speed of light is invariable. When the speed of a body changes, its dimensions and its mass and its time also change. As it speeds up, it shrinks (in the direction of the motion); its clocks slow down; its matter grows heavier. If the earth were to reach a speed of 161,000 m p s, every pound of matter in it would double in weight...
