Magnified 47,500 times, the head of a pin would cover about --; as much area as a football field. Its apparently smooth surface would show irregularities as startling as these
Electron micrography can produce magnifications even greater than this. The electron microscope, by itself, magnifies as much as 10,000 times and records images on photographic plates. And these images are so sharp, so well defined, that photog- raphy can enlarge them even more-often as much as 20 times more . .
Because it plays this dual role in electron micrography.. because it both records and enlarges... photography is an integral part of the new technic that is adding knowledge of tremendous value to many branches of science.

Telet-an pictui-es- air traffic conti-ol by raclar Iglus television.
Teleran-radio eyes"for bind flying! Teleran (a contraction of TELE- vision - Radar Air Navigation) collects all of the necessary infor- mation on the ground by radar, and then instantly transmits a television picture of the assem- bled data to the pilot aloft in the airplane.
On his receiver the pilot sees a picture showing the position of his airplane and the position of all other aircraft near his altitude. This is superimposed upon a ter- rain map complete with route m,Ir1kLincs XX711_h-br ofnnrlifionn.
and unmistakable visual in- structions to make his job easier.
Teleran-another achievement of RCA-is being developed with Army Air Forces co-operation by RCA Laboratories and RCA Victor. Moreover, when you buy any product bearing the RCA or RCA Victor monogram, you get one of the finest instruments of its kind science has yet achieved.
