This past August, scientists at the National Institute of Standards and Technology (NIST) unveiled a development that could deliver a thousand-fold performance improvement over the quartz crystal ...
As a species, we are obsessed about time. Our technological exploits rely on an increasingly exact knowledge of time. For example, some communications systems require frequency uncertainty 10-11 ...
The temperature dependent characteristics of quartz crystals prevent time keeping also with state-of-the-art real time clocks from being highly accurate over a wide temperature range, unless ...
IF TIME waits for no man, then neither does human ingenuity in measuring its passing. Throughout history, more stable and accurate clocks have led to advances in communications and navigation. Now a ...
