PHONOGRAPH RECORDS RADIO PROGRAM

You can make a phonographic record of your own voice or record your favorite radio program through an attachment on a new combination radio and phonograph. The attachment does not interfere with the ordinary use of the instrument for playing a record or program.

For record making, a microphone picks up voices and transmits them to a blank record through an electric “pick-up” similar to the reproducing arm of a standard electrified phonograph.

Wanted: Science Talent

Scholarships await promising students who hurdle series of brain-busting tests.

By David O. Woodbury

MARINA PRAJMOVSKY came to this country from Finland when she was four. Her father was a Russian-born machinist, her mother a seamstress. While in high school at Farmingdale, N. Y., in 1942 she entered the first Science Talent Search, a competition held by the Science Clubs of America. Out of some 15,000 entrants Marina tied for first place.

The Search’s $2,400 scholarship got her started at Radcliffe. She graduated as the only sum ma cum laude in biology in the history of the college. In four years more she had a medical doctorate from Yale and now at 27 is doing research on eye diseases at Columbia-Presbyterian Medical Center in New York. Along the way she did highly secret work for the Navy and carried out outstanding research on DDT.

Aviation Novelties

Novices Learn Flying On the Roof
GROUND flying has been practiced for years, it is true, and some old-timer used to try starting from a roof; but the British invention at the left stays right on the roof, to which it is fixed by a pivot. All the controls of the plane can be operated by the student, under instruction.

The new Whitley “Hoverplane”, a device for the instruction of unfledged aviators, being demonstrated on the roof of London’s largest department store.

Highways of Speech

Necessity made the United States a nation of pioneers. Development came to us only by conquering the wilderness. For a hundred and fifty years we have been clearing farms and rearing communities where desolation was—bridging rivers and making roads—reaching out, step by step, to civilize three million square miles of country. One of the results has been the scattering of families in many places—the separation of parents and children, of brother and brother, by great distances.

Automatic “Prodder” Keeps Driver Awake

Falling asleep at the wheel is just about impossible when an automatic “prodder” is worn by the driver. The prodder consists of an alertness indicator developed at Tufts College of Psychology. The driver wears a headband containing electrodes that measure alertness. When drowsiness sets in and sleep threatens, the electrodes signal to the indicator which sets off a warning buzzer that instantly arouses the driver.

Full-Length Sleeping Cot Rests on Top of Automobile Seats

Now the traveler can install a relief bunk in his car — an aluminum cot that extends above the seats from front to rear. While one person drives the other can sleep in full-length comfort. Made of lightweight tubing, the cot is supported by legs resting above the instrument panel, on top of the two seats, and on the rear-window ledge. It is quickly removed or installed and can be folded for storage. When folded, it is easily packed into place along with any reasonable amount of luggage. The bed can be adjusted for use as a regular cot.

Engineering the Magic Carpet’s Flight

Problems in Mechanics that Make the “Movie” Engineer’s Profession Recall the Magician’s Miracles

BUILD me a magic carpet on which I can ride; a flying horse like Pegasus and arrange a set so that I can disappear in a whirlwind.”

The “boss” of the moving-picture lot, without more ado, walked out of his chief engineer’s office, leaving that hard-working individual the three problems which he mentally added to the score or more of similar commands he had executed since the actual “shooting” of the scenes in the huge spectacle had begun months ago. For the engineering staff of the larger moving-picture producers is used to facing and conquering problems that for sheer unusual-ness are perhaps unrivaled.
