The first NYE countdown can arguably be traced to the final seconds of 1957, when prominent radio correspondent Ben Grauer counted down the New Year’s Eve ball drop in New York City’s Times Square, ...

Atomic clocks, such as those used on the Global Navigation Satellite System network, are accurate, but only up to a point. Moving to even more precise navigation tools would require even more ...
