New RCA electron tube gives today's amazing computing machines an indispensable memory. Tuke wifh ar memory keeps a05nes/ 0on n/e So complex are present scien tific studies-such as in atomic research-that just working out the "arithmetic" could take all of our scientists' time. A short cut is found in elec tronic computers, capable of add ing or multiplying numbers as large as one thousand billions in millionths of a second. But such speed is valueless unless-with comparable speed-the results of countless computations can be kept "on file" and taken out again. Such a "file" now exists in the Selectron tube, developed at RCA Laboratories. Electronically it retains figures fed into calculating machines, holds them in storage while it memorizes new ones speeds intelligent solutions through mazes of mathematics. Uses of RCA's Selectron tube are many. It will help atomic scientists acquire new and needed knowledge ... provide new infor mation on supersonic flight ... even help make rapid weather predictions! It is an invaluable in strument in the scientist's cam paign to penetrate the unknown. For your benefit: Development of the Selectron tube is just one example of the many basic advances pioneered at RCA Laboratories. Continued leadership in science and engi neering adds value beyond price to any product or service of RCA and RCA Victor.
