THE TRANSISTOR'S 20th ANNIVERSARY
The nuts and bolts of modern electronics, transistors lie at the heart of our rockets, computers, radar, radio, TV, and a thousand other devices By W. STEVENSON BACON The time: December, 1947. The place: Bell Telephone Laboratories at Murray Hill, N.J. The event: the invention of a new kind of electronic "valve" that can amplify signals—an invention so basic that it will virtually remold all science and technology. Unlike the vacuum tube, it will not need a power-consuming hot filament, nor will it require a vacuum. Is it an impractical dream? Many skeptics think so. After years of experimenting, Bell scientists, faced with repeated failures, have turned back to basic research.

Amazing New Picturephone
A step closer to in-person By W. Stevenson Bacon There’s a brand-new Picturephone in the works that will one day give you instant total communication with anyone you call. What makes it fascinating is the amazing versatility of the delicately engineered unit that holds both picture and camera tubes. Unlike the old Picturephone, this one gives you a choice of wide-angle picture, long-range shot, or electronic close-up. Pull a lens out and aim it downward, and you can send pictures, drawings, or printed documents. If you wish, you can push a button to see what you’re sending. And if a call catches you in the shower you can simply switch over to three-bar test pattern. Bell Telephone Laboratories packed all this into an 8-by-11-by-14-inch box by using tiny integrated circuits that incorporate hundreds of transistors and other components on small chips of silicon. In fact, the only vacuum tubes used are the picture and camera tubes. And even the camera tube makes use of semiconductors. The camera tube is a revolutionary new type that uses a target (the part of the tube that converts incoming light to electrical charges) made of silicon and containing 300,000 light-sensitive diodes formed on it by integrated circuit techniques. It’s the first time that semiconductors and vacuum tubes have been combined to make one device.

Scariest Recruitment Ad Ever
Basically they are saying: “Choose the Army before the Army chooses you.” This reminds me of mafia thugs demanding protection money and saying: “We can do this the easy way, or we can do this the hard way.” He just lost his chance to make a choice. His induction notice caught him with his decisions […]
