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.

Measurement uncertainty represents a fundamental parameter in analytical chemistry, encapsulating the range within which the true value of a measurement is expected to lie. This concept is integral to ...

The technique which is recommended by the regulatory bodies ISO (International Organisation for Standardisation) and BIPM (Bureau International des Poids et Mesures) is one of the most comprehensive ...

GUM, the internationally approved technique for calculating measurement uncertainty, is reliant on the availability of a certified reference sample. Likewise, to find any repeatable offset (systematic ...

An important non-classical feature of quantum measurements is the celebrated uncertainty trade-off, namely that the uncertainties in the outcomes of measurements performed on distinct yet identically ...

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 ...

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 ...

So, you spend a good portion of your working hours making measurements, but how do you explain measurements to non-engineers, especially young ones? Here’s something to try with a child. Get a ruler.
