...microphone as small as a pinhead? It is on its way. A Raytheon Co. scientist has discovered that transistors, which are far smaller than any ordinary microphones, have areas that can detect fantastically faint mechanical forces and translate them into sizable changes of voltage -just as a microphone does...
Dropping his regular research to investigate, Dr. Rindner led a Raytheon task force in painstakingly devising a tiny bit of metal shaped like a thumb tack and mounting it so that its stem pressed on a transistor's sensitive spot. This device, smaller than a pinhead, performed as an excellent microphone. It can be made to transmit music faithfully, and can even pick up ultrasonic sounds to which the human ear does not respond...
From some newborn mice he cut out the pinhead-size thymuses. For three to four months, these mice seemed to get along as well as their unoperated litter mates...
...pinhead in this case is a young aristoclot called Freddy Widgeon. Poor Freddy. He has been enrolled by his wealthy, tyrannical uncle, Lord Blicester (pronounced Blister), as "a wage slave in a solicitor's firm, as near to being an office boy as makes no matter." Freddy is limply determined to escape to Kenya and become a "coffee king," but he has to earn a few beans before he can plant any, and this involves 246 pages of wild but cheerful complications. Among them: a girl named Sally, whom Freddy considers "the biggest thing since sliced bread," a lady...
...current to flow through the coils from a battery. The energized coils react with the magnets and keep the fork vibrating at a steady 360 cycles per second, giving a musical note a little higher than F above middle C. Each vibration pushes a jewel-tipped spring against a pinhead-sized wheel whose rim has 300 microscopic ratchet teeth. The turning of this wheel moves the hands of the watch through a conventional gear train. Bulova guarantees that its electronic watch, which it calls the Accutron. will not gain or lose more than one minute per month. Price of present...
