and portable, and it.s service will be Kreatly increased. In addition. RCA Laboratories has succeeded in de- veloping an electron micro-analyzer, which, incorporating an electron micro.scope. enables atomic identifi- cation of the chemical elements comprising submicroscopic parti- cles of matter. For example, if there is iron in the nucleus of a bacter- ium, the micro-analyzer detects it. Because of spectacular wartime developments, radio apparatus will be adapted for collision prevention to aircraft, ships, railroads and pos- sil)ly automobiles. All this will be part of the new service of radio in an era of sight control made pos- sible by the development of electron tubes in the field of microwaves. New Tubes Foreseen As new electron tubes always serve as keys to major advances, so in broadcast reception, new and tiny tubes—smaller than acorns— nia\- introduce "personalized" radio. Small, compact receivers, and even transmitters may be built in a little case that will slip into a pocket. The uses to which such "stations" may be put gives the imagination much to play upon. All these new developments will not be realized in 1944, but with 1944 as the year of expected deci- sion in the European war, they will date from it, as radio broadcasting dated from 1919. The new ideas, tools and instru- ments of progress that emerge from the war may well give us 1960 radio in 19.50. War shrinks the lapse of time between invention and its practical use. The merit of a dis- covery is quickly appraised and harnessed. While we can see all these signs of progress, we must not lose sight of the losses suffered to the world through the casualties of battle. The boy who fell in the jungles of Guadalcanal, on the sands of Africa, on the road to Rome, who vanished in the Atlantic or Pacific or parachuted into the realm of missing warriors, may well have carried with him a revolutionary idea. When we review a year of war we wonder what might have been tiie fate of wireless had war taken the lives of such men as Maxwell, Ilei'tz, Marconi, deForest, Alexan- derson. Armstrong and Zworykin. in their youth. But the young men, lost to the world and to science in this war, have, in their supreme sacrifice, made it possible for the civilized world to progress: they have con- tributed far more than invention. They have made future invention possible by the defense of a civiliza- tion in which men can think, study. work and achieve for the welfare of mankind under freedom and justice. We may look forward to 1944 with high hopes, bulwarked by a determination never to break faith with those who have fallen, or with those who are marching with the Stars and Stripes, on the bomb- infested road to Victorv. RADIO-ELECTRONIC DEVICES. SUCH AS THE RIVET DETONATOR (RIGHT), HAVE GREATLY SPEEDED UP PRODUCTION FOR WAR IN NUMER- OUS BRANCHES OF INDUSTRY.
