I previously talked about measurements (some) when I looked at the uncertainty in the distance to the Sun. One of the simple ways of determining the uncertainty of a calculated quantity is to use the ...
Monte Carlo methods have emerged as a crucial tool in the evaluation of measurement uncertainty, particularly for complex or non-linear measurement systems. By propagating full probability ...
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 ...
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 ...

Measurement precedes prediction (I): Why data is not enough: Measurement as strategic infrastructure
Although most modern organisations possess extensive data, a subtler challenge persists: a lack of understanding regarding ...
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.
Hewlett-Packard (now Agilent Technologies) once offered a useful little cardboard slide rule for calculating the uncertainty in RF measurements stemming from VSWR (voltage-standing-wave-ratio) ...
What is the meaning of Heisenberg’s analogy? (Courtesy: German Federal Archives) A row has broken out among physicists over an analogy used by Werner Heisenberg in 1927 to make sense of his famous ...
