Cuando el tic-tac se convirtió en zumbido, la medición del tiempo revolucionó
Abstract
In the early 1960s, a technological development emerged that revolutionized time measurement, radically increasing the accuracy of watches. Although it became famous for its use in wristwatches, it appeared at an epoch when the space industry, and even the operation of espionage and Cold War-related satellites and aircraft, benefited from it. In wristwatches, the timekeeping element, that is, the system that divides time into intervals as constant as possible, was the balance wheel with hairspring; that small ring that even today moves endlessly in mechanical watches. The system described here is totally different: it is based on the vibrations of a tuning fork, like those used in music, but tiny and vibrating with a surprisingly high frequency, so that the second hand on the watch jumps 360 times per second; a “tick-tock” too fast to tell apart.
