Precision can be defined as the closeness in agreement of results during a series of repeat measurements under presumed identical conditions. These results are often expressed as a standard deviation.

Many people use the words “accuracy,” “precision,” and “resolution” as if they were synonyms, even though they are all very different. For example, datasheets for products as diverse as test & ...

Precision measurements in atomic and ion physics have become a cornerstone for testing the limits of our understanding of quantum electrodynamics (QED) and the Standard Model. By harnessing ...
