...means of a cloud chamber they are now able to see and photograph the stream of protons from their machine. The effect looks like a stubby shaving brush with bristles 1.6 in. long. Each bristle is the path made by a proton only one 10,000th of null millionth of an inch in diameter...
Last week, at the end of the infantile paralysis season, three Stanford University men announced that they had isolated and measured an organism which they were certain caused infantile paralysis. The organism measures less than one-half millionth of an inch. The investigators- Drs. Charles Eglof Clifton, Edwin William Schultz and Louis Philipp Gebhardt-figured the size by filtering material from a case of infantile paralysis through the pores of unglazed, fine porcelain. They knew the size of the pores. The filtrate caused the active disease in monkeys. That confirmed the doctors' belief that they possessed the cause...
...weigh an electron, others which weigh bridges. They bend steel girders at the bureau and blow up steel tanks. One device, an interferometer, indicates how far a 40-in. brick wall is deflected by the pressure of one hand. They have an ultramicrometer which measures a movement of one-millionth part of an inch. But it is "too sensitive for any known...
...means of an instrument so sensitive as to register a variation of one-one-millionth in an assigned wave length a 1,000 mi. away, the staff of ten at Grand Island will check between 300 and 400 wireless and broadcasting stations during a 24-hour working day. Not only will the wave wobbling of U. S. stations be detected but those in Canada and Mexico will be watched to see they do not creep out of the channels allotted them by international agreements. Entertainment programs will be brought in to evaluate their public worth, though no censorship will...

Through that taper the earth's atmosphere very, very slowly escapes into universal chaos, a millionth part in a million years...
