Measurement uncertainty, as described in ISO/IEC Guide 98, is a “parameter, associated with the result of a measurement, [which] characterizes the dispersion of values that could reasonably be ...

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.

Quantum measurement and uncertainty relations lie at the heart of quantum mechanics, delineating fundamental limits on the precision with which non-commuting observables can be simultaneously ...

Accurately tracking atmospheric greenhouse gases requires not only fast predictions but also reliable estimates of ...

Based on the EURAMET Calibration Guide No. 18 “Guidelines on the Calibration of Non-Automatic Weighing Instruments” 1–3 (represented as “EURAMET cg-18”), this QApp function offers a dynamic display of ...

Scientific progress has been inseparable from better measurements. Before 1927, only human ingenuity seemed to limit how precisely we could measure things. Then Werner Heisenberg discovered that ...

Scientists find a 'measure and remeasure' approach is a feasible method of verifying soil carbon storage in croplands for climate mitigation. Directly measuring soil carbon rather than relying on ...
