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 ...

The rules of statistical physics address the uncertainty about the state of a system that arises when that system interacts with its environment. But they've long missed another kind. In a new paper, ...

Every year an increasing number of laboratories using OES (Optical Emission Spectroscopy) spectrometers get accredited according to DIN EN ISO 17025. Compliance with DIN EN ISO 17025 has elevated the ...

For almost a century, Heisenberg's uncertainty principle has stood as one of the defining ideas of quantum physics: a particle's position and momentum cannot be known at the same time with absolute ...

Two studies published in 2022 demonstrate machine learning techniques employed to reduce uncertainty in atomic force microscopy (AFM). Making AFM more accurate with artificial intelligence (AI) could ...

The Heisenberg Uncertainty Principle, formulated by physicist Werner Heisenberg in 1927, reminds us that there are fundamental limits to what can be known simultaneously about certain pairs of ...

Improvements to the SI are helping to evolve the science of accuracy and measurement. Democratization of the SI creates a traceability calibration chain accessible to anyone, anywhere. Digitization of ...
