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 ...

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 ...

How does Thermo Fisher Scientific's analytical software support the calculation of measurement uncertainty? Wilhelm Sanders: According to DIN EN ISO 17025, it is necessary to calculate the measurement ...

In order to use the result of a chemical analysis for other purposes, its quality must be assessed. One important quality feature is the probability that the result coincides with the ‘true’ value. It ...

Researchers have captured and controlled quantum uncertainty in real time using ultrafast squeezed light pulses (CREDIT: Light Science & Applications) In a stunning leap for quantum optics, scientists ...

By using something called a quantum grid, scientists have found a clever way to simultaneously measure momentum and position ...

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 ...

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.

Though the principle is not violated, a new way of fudging its restrictions could lead to improvements in ultra-precise ...

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 ...

In a stunning leap for quantum optics, scientists have generated ultrafast light pulses whose quantum uncertainty can be directly controlled and observed in real time. The achievement pushes the ...
