THE JAP NAVY is one of the enigmas of the war in the Pacific. Just how good would it be in a full-dress, showdown fight with our surface fleets? Are its vaunted secret superdreadnoughts a match for our mighty Iowa-class battlewagons? Alden P. Armagnac gives you an up-to-the-minute appraisal of Japanese sea-power as the curtain rises on the last act of the battle for Asia.

DOWN here in St. Petersburg, Fla., we are celebrating the twenty-first birthday of the land version of deck shuffleboard. Since the game is one in which science figures as well as skill, it seems to me that P.S.M. should recognize its coming of age as a game that is not restricted to the deck of a ship.

DEVON FRANCIS
OUT of three years of air warfare ranging over much of the 63,000,000 square miles of the Pacific, a new pattern of Japanese defensive tactics is developing. They bode harder going for the United Nations as they approach the core of Jap resistance.

TED STEELE
AT THE end of its sector, a lone Navy search plane turned away from home. For six hours the pilot had flown his Liberator over a huge, empty, and beautifully monotonous pie-slice of ocean trying to find any Japanese movement by submarine, surface craft, or plane.

ALDEN P. ARMAGNAC
Bzz . . bzz . . bzzz—” The 45,000-ton U.S.S. Iowa, mightiest battleship ever built, cleaves gray-green Atlantic waters at top speed. A red flag surmounting a signal halyard tells fishing smacks to stand clear. And through wads of cotton stuffed in the ears of sailors and landlubbers, bunched near the prow, filters the penetrating sound of a buzzer.

A HOT reception is guaranteed enemy fighter planes attacking U. S. heavy bombers, thanks to the K-8 electronic gun sight. Invented by Erwin Hale and Irving Doyle, of the Fairchild Camera & Instrument Corp., New York, the new sight is said to extend the effective range of a .50 caliber machine gun from 600 to above 1,000 yards.

NOW a stranded man can be snatched off the ground by an airplane in full flight. The equipment needed to pick him up without stopping has been perfected by Army Air Forces, and four men have experienced this new thrill. The apparatus is similar to that used to lift gliders off fields where planes cannot land.

One victim, in fact, was found still standing in a pub with a drink in his hand, but dead.

You Can See Blast

PROF. A. M. LOW
"TO SEE blast, appears at first to savor of spiritualism. In fact, it is a very simple phenomenon and illustrates a principle which has been used for many years by some architects to discover the acoustics of a building before it is erected. Like other forms of noise or sound, blast is usually propagated by alternate waves of compression and rarefaction in the air.

EXCEPTIONAL resistance to heat characterizes silicone rubber, an entirely new synthetic product developed by General Electric research engineers. Rings of the material now replace asbestos to cushion the glass of naval searchlights and blinker signal lamps against the terrific shock of gunfire, materially reducing breakage.

During 11 months’ operation at The Glenn L. Martin Co., Baltimore, Md., the saving of 1¼ seconds on each of the 3,000,000 parts that went through the machine added up to more than 1,040 man-hours.

IN THE Far East, a formidable ally of Japan confronts our armed forces. On the home front, a fifth-column agency kills 3,000 Americans and inflicts 2,000,000 casualties a year. The same potent menace may well have caused the downfall of the ancient Greek and Roman civilizations.

Nineteen U. S. Inventions That Changed the World
YANKEE GENIUS has improved the lot of the whole human family and altered the course of history. We asked Miles Henninger, patent lawyer and close student of American invention, to name the U. S. patents that he considers most momentous in world progress. Eight of his choices are described here, and 11 more will be covered in a later installment. Mr. Henninger is associated with the law firm of Lecher, Michael, Spohn & Best, of Milwaukee, Wis. His selection is based on material collected for an article in the Allis-Chalmers Electrical Review.

CYRUS McCORMICK perfected the reaper after his father abandoned experiments begun in 1816. McCormick had a grade-school education plus experience on his father’s farm and in his father’s sawmill, grist mill, and black-smith shop. When the father dropped its development, the reaper had a reel for pressing grain against rotating knives; the cut grain fell on a platform from which it had to be raked by hand and then bound.

FRICTION IS RESISTANCE to the movement of one object or substance over or through another. When we walk, row a boat, pull a sled, drive a car, or fly a plane, we encounter friction either as a help or a hindrance. If we want something to move readily, we seek to reduce friction; if we want an object to grip another, we try to increase friction.
