...Association for the Advancement of Science was holding its annual meeting, and informed the whole scientific world 1) that a virus was a huge molecule composed basically of nitrogen, carbon, hydrogen and oxygen, weighing 17,000,000 times as-much as a hydrogen molecule, and measuring one seven-hundred-thousandth of an inch in diameter; 2) that he had crystallized a typical virus (which causes mosaic diseases in tobacco plants) by chemical treatment; 3) that he had modified the virus molecule chemically and produced other types of plant disease; 4) that he had made the molecule inactive. All this proved...
Darrah made his identification by a new process he has perfected, and through which it is possible to peel from a specimen a transparent cross-section, one twenty-five thousandth of an inch thick for microscopic study...
Still another question which it is hoped 1937 will uncover is that of the tiny dust particles floating through space, which account for many of the unusual qualities of light. They range in size from one ten thousandth of an inch to one ten millionth...
...each side of each intersection Engineer Dorsey removed the straight white stripe, substituted a stripe with a snake-like wriggle. In the white paint are millions of glass beads one twenty-thousandth of an inch in diameter, making the wavy line a streak of fire in the headlights. Observing that 64% of California crashes occur at night, he explained that it would take time to test his signal's efficiency. Typical driver reaction was that of Fire Chief Ralph Scott. Encountering the wriggle for the first time, he snorted to his wife: "You know, I'm not drunk...
...examine their products. In Pierce Hall is a Cathode Ray Oscillograph machine which measures a movement taking place in forty-millionths of a second, the first high-voltage transmitter in the country, and massive soil testing engines whose four foot beams are knife-edged to the accuracy of a thousandth of an inch...
