"SHAKEDOWN" LABORATORY for Navy Ordnance
ON HIS birthday, Rear Admiral Frank E. Beatty was given a crosscut saw by officers, bluejackets and civilian scientists of the Naval Ordnance Laboratory in Washington, D. C. "What's this for?" he asked. "A professional joke," said a spokesman. "We figured that you'd need something to help cut up those knotty problems we're going to run into at White Oak." White Oak—938 acres of rolling Maryland countryside 12 miles north of Washington, D. C.—is one of the Navy Bureau of Ordnance's newest research centers.

COPS ON THE CAMPUS
At the Traffic institute, veteran officers —finest in the country—are pumped full of facts on how accidents happen and how to help motorists behave By Clifford B. Hicks SEVENTEEN HUNDRED police officers from every section of the country have been learning the finer points of traffic enforcement at Northwestern University's Traffic Institute since 1936. It's not entirely coincidence that the national death rate per 100,000,000 vehicle miles has been cut more than half—since 1936. Even faculty members don't suggest that the institute is solely responsible for this startling reduction in fatalities. Yet during the past 12 years those 1700 officers, crammed with knowledge of how accidents happen and what to do to prevent them, have taken over key positions on traffic police forces throughout the country. And the institute's sister organization, the Traffic Division of the International Association of Chiefs of Police, has probed traffic enforcement in 60 cities, counties and states and made recommendations that invariably have brought surprising slashes in the accident rate.

Radios in Your Hair
RADIO receivers, tinier than a penny matchbox have been developed by Paramount sound men in Hollywood. These replace the megaphones that directors used in the days of silent pictures to shout instructions to their stars. The resulting confusion on crowded sets was nerve racking to both the director and members of the cast. When sound was added, the megaphone had to go. It was then replaced by intricate signaling systems and many necessary interruptions and expensive retakes. Now this tiny inductive-type receiver, that uses no batteries or tubes, is concealed on the actor's person. It is claimed that it can pick up signals as far as 300 feet away from the transmitter which is placed near the movie studio stage.

Trial by "Sound Jury"
Trial by “Sound Jury” After Bell Laboratories engineers have designed a new talking circuit, they measure its characteristics by oscilloscopes and meters.

The Story of Rope
By Andrew Hamilton THE OLD INDIAN rope trick has amazed and mystified people for generations. A fakir throws a rope above the stage where it stands without apparent support, as stiff as a rod. The trick is simply this: an unnoticed four-pronged hook at the end catches a taut piano wire in the dim light above the stage. This vaudeville stunt is not half as amazing as the miracle of rope itself—one of mankind's most useful tools.
